Correct and high-quality construction of the roof of a house does not mean that upon completion construction work you can forget about it. In the future, the roof requires special and regular care, inspection or repair. You will need a convenient and quick exit to it. In addition, this is often the only way to get out of the house in case of emergency evacuation. The location for access to the roof through a hatch must be included in the project before construction begins. Next we will talk about how to choose the right one and what types of exit devices are available on the roof and under its space.
Types of hatches and why they are needed
Surely you have heard that there are dormer windows, light windows, fire windows and attic windows - all these functions can be performed by a hatch. Yes, this is no longer just a cover, but rather a stylish and functional addition to the attic space. After all, it is often used as a full-fledged room - an attic.
Important: for those buildings whose area is less than 100 sq.m, the presence of a hatch is not strictly recommended. In other cases, where the area is larger than the norm, this is a mandatory measure enshrined in SNiP 21-01-97.
Firstly, the roof is a complex structure. Over time, damage to or under the roof covering may occur. Leaks, holes, cracks, etc. To figure out what's going on and fix the problem, you need to get on the roof.
Secondly, security measures. If a fire occurs, you can get out through the hatch on the roof when this cannot be done through the door. Indispensable for removing smoke.
Thirdly, on the roof there is a ventilation system, lighting elements, television antennas, a chimney, etc. This all requires periodic repairs, cleaning, and routine inspection. In addition, there is such a banal, but important thing how to remove debris from the roof.
Since the attic space turned into a residential attic, manufacturers began to produce beautiful and stylish hatches. They serve not only as an exit to the roof deck, but also as lighting and ventilation of the attic. It is both functional and original in terms of design.
Common types:
Dormer windows.
Luke-window.
Operational.
On sale you can mainly find standard sizes– 1200x1200 and 450x450. If your size is not available and the desired shape, then it can be made to individual order. But it will cost 30% more. Let's take a closer look at the popular options.
As mentioned above, there are roof windows. Some of them act as a hatch. Their advantage is that they not only fulfill their functional purpose, but also decorate the attic space with a play of light and shadow. They look just as impressive from the outside. The disadvantage of this type is its high cost and complex installation. As a rule, installation is carried out by specialists. No one takes the risk of producing it on their own, lest it result in wasted money.
A simple and inexpensive option is a hatch-window for a non-residential attic. It simultaneously serves as an exit to the roof and illuminates the room. Easy to install, does not require specialist assistance. Reinforced glass unit, polyurethane or wooden frame. It looks stylish in appearance and opens outwards. There are no obvious shortcomings. The only thing is that it is only suitable for unheated rooms and requires an extension ladder.
Wooden hatches have certain advantages. They represent a kind of transformer. This is a wooden lid, when you open it, you get a ladder, and when you close it, the ladder folds and hides under the lid. Such hatches do not provide lighting, but they are easy to install and practical to use. In terms of design, it is completely laconic and aesthetically pleasing. Mainly used for small private houses. The disadvantage is that the lid is not protected from the outside. It is imperative to take measures to shelter from weather influences that destroy the wood.
To organize access to flat roof service hatches are used. It is immediately worth noting that they are not distinguished by beauty and originality. Basically, this is a solid metal cover, equipped with a ladder also made of metal. Usually the lid does not allow light to pass through, but sometimes it is made from transparent material. Of course, in terms of design, they don’t really benefit from this. But if you consider that they are used for outbuildings or industrial facilities– such criteria as beauty and aesthetics in this case play the last role.
Which option you need depends on where the hatch will be installed. If this residential attic, then you should spare no expense on high-quality insulation of the exit, as well as on its design. For a non-residential attic, which is used as a storage for old things and household items, there is no point in overpaying for beauty. It is better to choose a simple but functional type of hatch.
How to get to the roof from outside the house
To climb onto the roof or reach the same hatch, use stepladders or external ladders. Manufacturers made sure that they not only provide practical benefits, but also combine with the design of the house. You can easily choose a high-quality and stylish item.
Most convenient option a steep external staircase is considered. Expensive models are made from of stainless steel. Its polished appearance gives the building a beautiful and rich look. Cheaper options are made of steel pipe with welded brackets into which corrugated steel steps are inserted. Railings can be made of cables, rods, pipes, etc.
The steps are not always steel - they can be made of any hard rocks tree. For example, ash or beech. Wood must be impregnated with special mixtures. Outdoor stairs are popular not only for their efficiency, but also for their attractive appearance.
This option is the cheapest and most convenient for accessing a flat roof, and this does not detract from its reliability at all. Nothing superfluous or pretentious. For fans of minimalism and practicality, this is a great option.
Important: the stepladder is attached to the wall of the house so that the last step from the bottom is at a distance of a meter from the ground. This is a safety measure for small children to prevent them from climbing up.
To use such a stepladder, you need to attach an extension ladder to it, and when you go back down, remove it. Pay attention to what your stepladder is made of. Metal elements must be coated with varnish or polymer mixtures - this will protect against rust. Steps should be either corrugated steel or rebar that has projections. This is important so that they are not slippery.
Brief installation diagram:
The first step is to select a location for the future hatch.
WITH inside The exit area is marked on the roof.
Insulation and waterproofing are carefully removed from it.
Then nails are driven into each corner where the hatch will be located.
Marks are made on the rafters.
Where the hatch goes out, they nail it wooden blocks so that the nails pierce through the sheathing. This will help you cut out the roof covering evenly from the outside, focusing on the nails.
When the cut is ready, the location of the reinforcing bars is noted.
Jambs are nailed at the top and bottom of the opening instead of rafters. They will increase support.
5x10 wood beams are nailed to the location of the beams.
To ensure that the sawn beams hold securely, two additional jambs are nailed into the ceiling from the inside.
The finished frame is covered with waterproofing and covered with plasterboard to protect it from moisture.
The hatch frame is secured to the frame using screws or nails, depending on the model.
Joints must be covered mineral wool or a special sealant.
You can carry out the installation work on installing the hatch yourself, but it is better to entrust it to a specialist. Simple types are easy to arrange yourself if you have the necessary skills. Models complex design It’s better to leave it in the hands of a master who will do everything efficiently and according to the rules.

Surely, many people who are involved in construction are interested in many topics related to roofing. The topic of this article has a slightly different perspective than the choice of roofing material and its installation. Today we will touch upon such an issue as access to the roof through a hatch and other systems of exits through the roof of the necessary passage elements.
A complete roof consists of more than a base structure, base sheets and drainage system elements.
A safe and functional roof includes various exit elements. These could be passages:
- ventilation systems;
- antennas;
- roof hatches;
- pass-through elements;
- roof vents and fans.
Modern elements of roof space exits are high quality products.
They have the following properties:
- easy to combine with roofing covering;
- have an elegant appearance;
- durable;
- reliable;
- provide ease of installation;
- easy to use.
Application area
Exit elements are used on those roofs where a technical and technological exit to the roof is required.
Technological exits to the roof are provided at the following construction sites:
- mansions;
- residential multi-storey buildings;
- terraced houses;
- kindergartens and school institutions;
- during the reconstruction of ancient buildings;
- public buildings;
- non-residential premises.
Technical outputs (ventilation elements and antennas) are applicable in functioning buildings of any type and with various types roofs. The modern range of products allows you to select components for technical outlets that match the roofing.
Attention. The presence of exits must be provided for at the roof design stage.
Exit methods
Let's look at the technological outputs that are required to carry out the following actions:
- roof repair work;
- roofing cleaning;
- fire extinguishing;
- roof operation.
There are several ways to reach the roof plane, which depend on the purpose of the under-roof space and the slope of the roof slope.
These include:
- stepladder located vertically along the wall;
- external staircase;
- folding ladder;
- roof ladder;
- roof window;
- not insulated hatch window.
Characteristics of hatches
Exit to the roof - hatch, installed in multi-storey buildings on the top floor above staircase. The location of the hatch in roofs with slopes depends on the pitch of the rafter beams.
According to building codes, the distance between the rafters and the hatch frame should be no higher than 70 mm. On roofs with a large area, several hatches are installed. Traditional hatch sizes include designs measuring 45x55 cm and 120x120 cm.
The roof hatch has a cover, the surface of which is treated with a primer and paint composition. To ensure that the manhole cover does not stand out from the entire roofing carpet, it is lined with the main material.
Hatches can open in two directions: to the side and up. Gas springs secure the lid in the open position.
When installing a hatch, great importance is given to its thermal insulation properties if it is installed in a heated room. Exit through the hatch is via a fixed metal structure.
Advice. If the roof design does not allow compliance with the installation requirements, then the designer’s conclusion must be provided for the implementation of another option for arranging the hatch.
Properties of roof windows
A roof window, as an exit to the roof, is installed in the attic. Manufacturers of roof windows now offer products for pitched and flat roofs.
Windows perform the following functions:
- ventilation of the attic;
- emergency exit to the roof.
When installing dormer window on a flat roof load-bearing elements a box is mounted, the upper part of the slope of which is 19 degrees. Then a window is placed on the body.
Typically, roof windows designed for heated attic spaces have the following dimensions: 66x118 cm, 94x140 cm.
Sealing collars are placed on the edges of the windows where they adjoin the roofing sheet, which prevents water from leaking in and provides thermal insulation.
Attention. To ensure better thermal insulation properties and high-quality styling seal, the opening for the roof windows should be 6 cm larger than its frame.
Vertical stepladder
The easiest way to the roof is a stepladder located vertically outer wall. To prevent children from being lifted onto the roof, the lower edge of the structure should be 1 m away from the ground.
When arranging a stepladder, it is important that the surface of the steps does not slip. To make them take:
- corrugated steel;
- crescent-shaped fittings.
As a rule, to extend its service life, a stepladder is coated with an anti-corrosion coating using a powder composition or paint and varnish material.
Construction of an external staircase
Many people prefer to use an external ladder instead of a stepladder for flat roofs. As a rule, the design of such stairs contains metal and wooden elements that require anti-corrosion and antiseptic treatment, respectively.
To make external stairs as an exit to the roof, you can use:
- corrugated steel;
- polished steel;
- stainless steel;
- impregnated oak, ash or beech wood.
Application of folding stairs
Folding stairs for access to the roof are used if there is an internal cover in the hatch, which helps hide the staircase structure. As a rule, such exits facilitate access to the roof from the interior of the structure.
The internal hatch covers, hiding them, are up to 6.6 cm thick and have a dense layer of thermal insulation.
There are several types of folding stairs:
- scissor;
- sectional.
The sectional allows users to safely ascend and descend the sunroof. They consist of several segments and are more popular than accordion-style scissor designs.
Advice. The use of hatches with an internal cover and folding stairs is recommended between rooms with different temperature conditions(residential and non-residential).
Roof drains
The exit is provided by a roof ladder, movement along which is similar to movement on a stepladder, with the difference that the ladder is located on the surface of the roof.
The ladder can consist of single steps or several, making up a single structure. A ladder located along the ridge, as a rule, leads from the hatch structure to the chimney, which facilitates the work of cleaning the chimney.
With a small slope of the roof, the steps of the ladder are installed at a distance of 70 cm from one another; with a slope of more than 30 degrees, the distance is reduced to 35 cm.
Steel ladders do not always match the roofing, so in most cases they are made from wooden blocks.
Mount any option from the above-described roof exits, and you will be able to carry out all the full-scale work on the roof surface for its long-term operation and safety of residence.
In order to be able to fully monitor the integrity of the roof, as well as for the purpose of carrying out repair work, convenient and safe access to it must be provided. This problem can be solved in several ways, each of which is selected depending on the slope of the slopes and the type of attic. This article will discuss how to arrange access to the roof so that it is safe and free of obstacles.
As an option, the roof can be equipped with insulated and non-insulated hatches, which will allow easy access to any roof elements. In addition, the roof can be accessed through the attic through attic and dormer windows. The number of exits to the roof is determined by its area and building regulations. On houses with one floor, the roof of which has an area of up to 100 square meters, it may not have access to the surface.
Access to a flat or used roof
The easiest way to arrange access to a flat roof is to install a stepladder on external wall Houses. Its lower step should be located 1 m from the ground. This will prevent small children from getting onto the roof without assistance. Adults, by placing a ladder, can easily climb to the roof.
It is worth noting that the steps of the stepladder should not slide. For this purpose they are made of corrugated steel. In addition, all its metal parts must be covered with some kind of polymer material that prevents them from rusting.
If you plan to install a balcony or terrace on the top floor, then a stepladder can be placed there too. Climbing onto the roof will be somewhat easier and less dangerous, but you will need to make your way through the house, which in some cases may be inconvenient.
Installation of an external staircase on a slope
A more attractive option would be to use a steep external staircase, which will connect the lower floor terrace with any platform located at roof level. Not only does it look beautiful in appearance, it is also more convenient to use than a stepladder. For its production are used steel pipes, to which brackets are welded for subsequent fastening of the corrugated steps. The steps can be made of treated hard wood: oak, ash or beech. To make it easier to climb and descend stairs, railings are made of rods, pipes or other materials.
It is worth noting that if you have the means, it is better to make an external staircase from polished stainless steel. This design looks perfect in appearance and will last much longer.
Installation of extensions for access to the roof
To access the flat roof, special superstructures are installed, which are placed above the stairs. They are also called booths - their shape can vary greatly.
A superstructure is made to access the roof in use, usually from brick, after which the structure is covered with a roof. An opening is made in the wall to install a door on the roof. To get into the superstructure from the house, you need to use the hatch, to which there is a ladder.
Requirements for access to the roof through the hatch
The use of hatches installed above landings on upper floors is considered universal option roof exit devices, both flat and pitched type. On pitched roofs, the placement of the hatch box is determined by the pitch of the rafters. It must be borne in mind that the gap between the rafters and the hatch structure should be less than 7 cm. If the gap is large, then 2 transverse beams are installed between the rafters, after which one is fixed vertically to them. And it is to this last block that one side of the hatch box is attached. If the gap to the rafters is less than required, then you will have to make a certain cutout from some rafter leg. After this, the cut edges are fixed using transverse frontal beams to nearby rafters to evenly distribute the load.
It is worth noting that if such access to the roof was not intended at the planning stage, then you will need to contact the designer for a solution to correct this nuance with all the ensuing work on intervention in the roof rafter system.
On those pitched roofs that have a large area and where there are several smokers and other devices that require systematic maintenance, it is advisable to install several hatches. It is important to note that in this case there is no need to install walkways on the roof.
The length of one side of a standard hatch ranges from 45 to 120 cm. Hatches with other sizes are made to order, and their price increases by 30%. According to the design, the hatch covers can be opened both to the sides and to the top. The lid is held open by gas springs. Hatches, which are produced commercially, are equipped with a protection system against accidental closing of the lid. There are also products with burglary protection. Manhole covers are given the same style as the surrounding roof. Great view They also have transparent lids, which are made of glass or polycarbonate.
It is worth noting that those hatches that will be installed above living spaces with heating must also be insulated. And those that will be located above the attic, which is used extremely rarely, do not need to be insulated.
Access to the pitched roof through the attic windows
Residential attics are equipped with dormer windows, which are installed in the open under-roof space. They are designed not only for lighting, but also to provide access to the roof. Manufacturers offer many window models designed for installation on pitched or flat roofs. On roofs with flat slopes minimum slope, will need to be built wooden frame, whose top should have a slope of 19 degrees. It is important that the dimensions of the frame exceed the dimensions of the window by approximately 50-70 mm. A finished window will be installed in it.
According to the requirements, the exit to the roof must be reliably sealed, which is achieved by installing special sealing collars. On reverse side a special plastic mixture is applied to the cuffs, which will prevent moisture from entering the cracks and also increase thermal insulation properties hatch. Cuffs are made of copper, aluminum, and a zinc-titanium alloy.
Application of folding stairs
Exit to pitched roof using folding stairs will allow you to disguise the exit and expand the usable area of the room without disturbing its interior. Thanks to the internal hatch cover, it is possible to hide the entire staircase structure. The thickness of the internal covers, taking into account the installation of the insulating layer, can reach up to 66 mm.
Folding stairs are:
- multi-sectional;
- scissors.
Due to their design, multi-section stairs are easier to use. Compared to scissor ladders, they are easier to fold and unfold.
Installation of ladders and steps for roofing
Whatever roof access is used, it is better if it is equipped with additional roof steps and ladders. In this case, you should ensure that they are corrugated or perforated. Such special devices will make moving on a sloping roof easier and safer. It is worth noting that the steeper the design of the ramps, the ladder steps should be placed more often. To make the steps, take strip steel 4 mm thick and 40 mm wide.
Please note that installing roof drains will make it possible to protect roofing material from mechanical damage, which quite often arise during the maintenance of smokers and other elements located on the roof surface.
In order to fix the steps, special fasteners for tiles are used, which have a concrete or aluminum overlay. This part, together with the step, is attached to the block using two bolts. After this, the block is nailed to the rafter legs.
Standard steel ladders have a width of 250 mm, and their length can range from 40 to 300 cm. Long ladders are fixed along the entire length of the ridge. Wooden ladders are made from bars with a cross-section equal to or greater than 4 cm.
The construction of roofs with access to the roof can be accompanied by a large number of difficulties and nuances, which sometimes only experienced specialists who fully master all the intricacies of roofing craftsmanship can cope with. If the owner turns to specialized companies for help, then he can count on the fact that all technologies during the construction process will be taken into account, so that the finished structure will be of the highest quality and durability.
To monitor the condition of the roof and carry out repair work, it is necessary to provide a convenient and safe exit to the roof. There are several ways to solve this problem, from which the most suitable one is selected. suitable option taking into account the angle of inclination of the roof slopes and the purpose of the attic space. To provide access to the roof, ladders installed outside the house or vertical stepladders are used. Inside the cottages, folding stairs equipped with a hinged lid are used.
In addition, insulated and non-insulated hatches can be built into the roof structure, providing reliable access to all roof elements. Also, access to the roof can be provided from the attic through attic and dormer windows. The number of exits to the roof depends on its area and is regulated by building codes. On one-story buildings with roofs, the area of which does not exceed 100 square meters. m, you don’t have to equip an exit to the roof at all.
Exit to flat roof
The easiest way to build an exit to a flat roof is with a stepladder attached to the outer wall of the house. In this case, the lower step is located a meter from the ground surface. This will prevent small children from trying to climb onto the roof on their own. Adults, if necessary, place an extension ladder on the fixed stepladder and easily climb up.
No matter how beautiful, durable and reliable your roof is, it will still need inspection and maintenance. Such work can be done if it has a special exit to the roof through a hatch. The most important thing is that it is comfortable, reliable and ensures the safety of people on the roof. This article will talk about various options access to the roof using hatches and other systems and passage elements.
The exit device will be determined by the purpose of the attic and the slope of the roof plane. It can be done in several ways - climb the familiar wooden or metal stairs located outside the building. This can be done using the stairs, which are located inside the house. Will help you achieve your goal ladder or a stepladder, which is placed against the hatch inside the house attic floor. You can get to the roof from the attic using a dormer or dormer window.
When they talk about a complete roof package, they mean not only the structure, which includes the base, material finishing coating And drainage system. If you look at it carefully from the outside, then, even without professional knowledge, you can notice the antennas and ventilation outlets located on it. In addition to them, the following are placed on the roof:
- roof hatches;
- valves and fans;
- pass-through elements;
- skylights;
- chimney pipes and so on.
The elements of roof exits that exist today are of high quality and are modern products. Among their advantages are:
- attractive appearance;
- reliability and durability;
- ease of use;
- harmonious combination with the finishing coating;
- ease of installation.
Application of roof outlets
It is necessary to use various exit elements on roofs that require technological and technical inspection of this important design Houses.
The following construction projects require technological access to the roof:
- mansions;
- residential multi-storey buildings;
- children's preschool and school institutions;
- terraced houses;
- public buildings;
- non-residential buildings and structures;
- ancient houses during reconstruction.
A technical exit to the roof, provided for antennas and elements of the ventilation system, is required on all buildings in use, regardless of the type and type of roofing. Currently, thanks to the wide range of products, it is possible to select components for technical outlets for the desired finishing coating.
The presence and number of exits to the roof are determined during the design work on the roof installation.
Methods for accessing the roof
Listed above are objects that require technological outputs. You need to have them when you need to carry out the following actions:
- produce renovation work on the roof;
- clean the roof covering from snow, branches, etc.;
- carry out fire extinguishing work;
- do everything related to the operation of the roof.
The methods of accessing the roof surface to perform these actions will depend, first of all, on the purpose of the attic space, as well as the angle of inclination of the roof slope. You can reach it using some devices and items:
- a stepladder mounted vertically to the wall;
- vertical external stairs;
- insulated and cold hatches;
- folding stairs;
- roof ladders;
- skylights;
- sliding stairs.
Distinctive features of hatches
Hatch for access to the roof in multi-storey buildings residential buildings arranged on the top floor in the ceiling above the last staircase. IN this option the metal vertical ladder leading to it is attached to the floor of the landing, the edge of the hatch and the railings enclosing the landing.
When constructing an exit to a pitched roof, the hatch is positioned taking into account the pitch of the rafter legs.
Roofs with large areas require the installation of several hatches. Traditionally, manufacturers offer the following sizes for these structures: 45x45 cm and 120x120 cm.
The surface of the roof hatch cover is treated with primers and paint and varnish compositions. The roofing carpet must have the same appearance over its entire surface, so the manhole cover is lined with the material used for the finishing coating. In some cases, manhole covers may have a translucent structure.
It should be borne in mind that when designing such an exit to the roof, SNiP requires maintaining a certain distance between the hatch frame and the rafter beams. The hatch trim and the nearest rafter should be at a distance of about 7 cm from each other.
Hatches must open in two directions - up and to the side. Gas springs are used to secure the lid in the open position. For the safety of house residents, hatches can be equipped with a lock or have a metal grill with a shutter.
If the hatch is installed in a heated room, then it is necessary to pay attention to its thermal insulation properties. You need to exit through the hatch hole using a fixed metal structure.
If, when installing a hatch, it is not possible to strictly comply with the design conditions, then another option will additionally require the conclusion of the designer.
In part fire safety the number of exits to the roof is regulated by SNIPs. TO the best option We can include an option in which the exit hatch is located next to the chimney pipe. In this case, there will be no need to install additional drains to service the chimneys.
When the attic is turned into an attic living space, the hatch, in this case, is combined with a window. Non-residential attic spaces have simple, uninsulated hatches.
Exit to the roof through the attic window
In the case when the attic is used as a living space, it is quite possible to use a dormer window to access the roof. Today, the production of roof windows has been established, both for pitched roofs and for flat ones. They are used for emergency exit to the roof, as well as for ventilation of rooms located in the attic space.
For flat roofs, before installing a roof window, a box is made under it. In relation to the roof, it has a slope of 10-20 degrees.
Size standard windows, which can serve as an exit to the roof in heated attic rooms, may be different. In most cases, they have dimensions of 66x118 cm, 94x140 cm. All of them are equipped with sealing elements (cuffs) that prevent moisture from entering the interior space. The seals simultaneously act as a heat-insulating material.
You can ensure the best thermal insulation properties of a roof window if you make the window opening 6 centimeters larger than the frame. This will also allow for better installation of the seal.
Exit to the roof using a stepladder
To one of the most simple ways The way to get onto the roof is to use a stepladder. It is located vertically along the outer wall. Such access to the roof, the norms of which prohibit lifting children, has limitations. The bottom of the structure should be raised above the ground to a height of 1 meter.
The stepladder must have a surface that is not slippery and therefore safe when lifting people. They are made from materials such as:
- corrugated steel;
- reinforcement having a crescent-shaped protrusion.
Since the stepladder is often on outdoors, to extend its service life, an anti-corrosion coating is produced. It is made using powder compositions or paints and varnishes.
Exit to the roof via an external staircase
To access a flat roof, instead of a stepladder, they often use external staircase. In most cases, its design consists of metal and wooden elements, which require appropriate antiseptic and anti-corrosion treatment.
External stairs used to access the roof are made of the following materials:
- corrugated steel;
- of stainless steel;
- polished steel;
- impregnated wood (oak, ash, beech).
To ensure safety, all stairs must be equipped with railings and securely attached to the walls of the building. Fire escapes made of metal angle or corrugated steel are mandatory in buildings above 2 floors.
Staircase structures must be subject to periodic inspection. The strength test is reflected in the documents of the organization servicing a particular building. Such staircases are used to access flat roof fire crews.
Climbing to the roof using a folding ladder
The use of folding ladders to access the roof is possible when the hatch has an internal cover that can hide the ladder structure. It has a thickness of up to 66 mm with a dense layer of thermal insulation. With the help of folding ladders one gets to the roof from the interior.
Among the types of folding stairs are:
- scissor,
- sectional.
Using sectional roofing ladders, you can safely climb to the hatch and descend. They include several segments. They are more popular than accordion-like scissor designs.
GOST recommends using hatches with an internal lid and folding stairs that provide access to the roof to connect rooms with different temperatures, i.e. residential and non-residential.
Using roof drains
A roof ladder is used to access the roof. You can move along it in the same way as on a stepladder. The only difference is that the ladder is located on the roof surface.
The ladder can be made in the form of single steps, as well as in the form of a single structure, which includes several steps. A ladder placed along the ridge usually leads towards the chimney. This arrangement makes it easier to access the chimneys during cleaning and other maintenance.
When the roof slope is small, the slope steps are installed in increments of 70 centimeters. When the roof slope is more than 30 degrees, this distance is reduced to 35 centimeters.
Steel ladders are not always in harmony with the roofing. For this reason, they are mainly made from wooden blocks.
Roof ladders made for human movement pitched roof, have the following dimensions - width 25-30 cm, length 40-300 centimeters. To avoid that the appearance of the roof will deteriorate from the placement of such additional elements, they are painted to match the existing topcoat.
If you install an exit to the roof according to one of the options described above, then you can do everything on the roof necessary work, which will ensure its long-term service and comfortable living for residents.
