Proper and high-quality construction of the roof of the house does not mean that at the end construction works 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 access to it. In addition, often the only way to get out of the house in case of an urgent evacuation. A place for access to the roof through the hatch must be included in the project before construction begins. Next, we will talk about how to choose the right one and what are the devices for exits to the roof and under its space.
Types of hatches and why they are needed
Surely you have heard that there are dormer windows, skylights, fire 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. 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.
First, the roof is a complex structure. Over time, damage to or under the roofing can occur. Leaks, holes, cracks, etc. To figure out what's wrong and fix the problem, you need to get on the roof.
Secondly, security measures. If there is a fire, then through the hatch on the roof you can get out when this is not possible through the door. Indispensable for removing smoke.
Thirdly, on the roof there is a ventilation system, lighting elements, television antennas, a chimney, etc. All this requires periodic repair, cleaning, scheduled inspection. In addition, there is such a banal, but important thing how to remove debris from the roof.
Since the attic turned into a residential attic, manufacturers began to produce beautiful and stylish hatches. They play the role of not only access to the roof area, but also lighting and ventilation of the attic. Both functional and original in terms of design.
Common types:
Skylights.
Luke window.
Operational.
On sale, you can mainly find standard sizes- 1200x1200 and 450x450. If your size is not available desired shape, it can be made to order. But it will cost 30% more. Let's take a closer look at popular options.
As mentioned above, there are skylights. 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. From the outside, they look just as impressive. The disadvantage of this type is high cost and complex installation. As a rule, installation is carried out by specialists. Nobody risks to produce it on their own, so that it does not turn into wasted money.
A simple and inexpensive option is a hatch window for a non-residential attic. It also serves as an exit to the roof and illuminates the room. Easy to install, does not require the help of a specialist. Reinforced double glazing, polyurethane or wooden frame. Outwardly looks stylish, opens outward. There are no obvious shortcomings. The only thing that is only suitable for unheated rooms and requires a ladder.
Wooden hatches have certain advantages. They are a kind of transformer. This is a wooden lid, opening which you get a ladder, and closing it, the ladder folds up 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 - complete conciseness and aesthetic appearance. They are mainly used for small private houses. Of the shortcomings - the insecurity of the cover from the outside. It is imperative to take measures to protect from weather conditions that destroy the wood.
To arrange access to flat roof use hatches. It is immediately worth noting that they do not differ in beauty and originality. Basically, this is a deaf metal cover, equipped with a ladder also made of metal. Usually the cover does not let light through, but sometimes it is made of transparent material. Of course, in terms of design, they do not really benefit from this. But given that they are used for outbuildings or industrial facilities- such a criterion 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 not spare money for high-quality insulation of the exit, as well as for its design. For a non-residential attic, which is used as a storage of old things and household items, it makes no sense to overpay for beauty. It is better to choose a hatch of a simple but functional type.
How to get to the roof outside the house
To climb onto the roof or get to the same hatch, use stepladders or outdoor ladders. Manufacturers made sure that they were not only practical, but also combined with the design of the house. You can easily find a quality and stylish thing.
Most convenient option considered to be a steep external staircase. Expensive models are made from of stainless steel. Its polished appearance gives the building a beautiful and rich look. Cheaper options made of steel pipe with welded brackets into which grooved steel steps are inserted. Railings can be made of cables, rods, pipes, etc.
The steps are not always steel - they can be from any hard rock tree. For example, ash or beech. Wood must be impregnated with special mixtures. The outdoor staircase is popular not only for its efficiency, but also for its attractive appearance.
This option is the cheapest and most convenient for access to a flat roof, and this does not detract from its reliability at all. Nothing extra or fancy. For fans of minimalism and practicality - a great option.
Important: the stepladder is attached to the wall of the house in such a way 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 so that they cannot climb up.
To use such a stepladder, you need to attach a ladder to it, and when you go down, remove it. Pay attention to what your ladder 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 with ledges. This is important so that they are not slippery.
Brief installation scheme:
The first step is to choose a place for the future hatch.
WITH inside the roof is marked with an exit area.
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 outside are nailed wooden bars so that the nails pierce through the skin. This will help to evenly cut the roof covering from the outside, focusing on the nails.
When the cut is ready, the location of the reinforcing bars is marked.
Jambs are nailed on top and bottom of the opening instead of rafters. They will increase support.
Wooden beams 5x10 are nailed to the location of the beams.
In order for the sawn beams to hold securely, two additional jambs are nailed from the inside in the ceiling.
The finished frame is covered with waterproofing and covered with drywall to protect it from moisture.
The hatch frame is fixed to the frame with self-tapping screws or nails, depending on the model.
Joints must be covered mineral wool or special sealant.
Installation work on the installation of the hatch can be carried out independently, but it is better to entrust a specialist. Simple types are easy to make yourself if you have the necessary skills. Models complex design it is better to give it into the hands of a master who will do everything efficiently and according to the rules.

Surely, many people who are engaged in construction are interested in many topics related to the roofing device. The topic of this article has a slightly different angle than the choice of roofing material and its installation. Today we will touch upon such an issue as access to the roof through the hatch and other systems of exits through the roof of the necessary passage elements.
A complete roof consists of more than just a substructure, base sheets and gutter elements.
A safe and functional roof includes various exit elements. These can be passages:
- ventilation systems;
- antennas;
- roof hatches;
- passing elements;
- roof valves and fans.
Modern elements of exits to the roof space are high quality products.
They have the following properties:
- easy to match with roofing;
- 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 high-rise buildings;
- houses of tape building;
- kindergartens and schools;
- during the reconstruction of old buildings;
- public facilities;
- non-residential premises.
Technical outputs (ventilation elements and antennas) are applicable in any type of functioning buildings and with various types roofs. The modern range of products allows you to choose components for technical outlets that correspond to the roofing.
Attention. The presence of outlets must be provided at the design stage of the roof.
Ways out
Let's focus on the technological outputs that are required to carry out the following actions:
- repair work on the roof;
- 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:
- a stepladder located vertically along the wall;
- outdoor staircase;
- folding ladder;
- roof ladder;
- roof window;
- not insulated hatch-window.
Characteristics of hatches
Exit to the roof - a hatch, equip in multi-storey buildings on the top floor above stairwell. The location of the hatch in roofs with slopes depends on the pitch of the rafters.
According to building codes, the distance between the rafters and the hatch box should not exceed 70 mm. On roofs with a large area, several hatches are installed. The traditional sizes of hatches include structures of 45x55 cm and 120x120 cm.
The roof hatch has a cover, the surface of which is treated with a primer and paint and varnish composition. In order for the manhole cover not to 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 mounted on a room that is heated. The exit through the hatch is carried out along a fixed metal structure.
Advice. If the roof design does not allow compliance with the installation requirements, then the conclusion of the designer must be made for the implementation of other options for arranging the hatch.
Roof window properties
The roof window, as an exit to the roof, is installed in the attic. Now manufacturers of skylights offer products for pitched and flat roofs.
Windows perform the following functions:
- ventilation of the attic;
- emergency exit to the roof.
When installing roof 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 cuffs are laid on the edges of the windows at the points of contact with the roofing sheet, which prevents water from flowing and provides thermal insulation.
Attention. To ensure the best thermal insulation properties and quality styling the opening for the roof windows must be 6 cm larger than its box.
Vertical ladder
The easiest way out to the roof is a ladder, located vertically. outer wall. To prevent children from climbing onto the roof, the lower edge of the structure must be 1 m away from the ground.
When arranging a ladder, it is important that the surface of the steps does not slip. For their manufacture take:
- corrugated steel;
- crescent-shaped reinforcement.
As a rule, to prolong the service life, the ladder is coated with an anti-corrosion coating using a powder composition or paintwork material.
External staircase device
Many people prefer to use an external ladder instead of a ladder for flat roofs. As a rule, the design of such stairs contains metal and wooden elements that require anti-corrosion and antiseptic treatment, respectively.
For the manufacture of 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 ladders
Folding ladders for access to the roof are used if there is an inner cover in the hatch, which helps to hide the ladder structure. As a rule, such exits contribute to getting on the roof from the internal space of the structure.
The inner hatch covers that hide are up to 6.6 cm thick and have a dense layer of thermal insulation.
There are several types of folding ladders:
- scissor;
- sectional.
The sectional provides users with a safe ascent to the sunroof and descent. They consist of several segments and are more popular than accordion-like scissor designs.
Advice. The use of hatches with an internal cover and folding ladders is recommended between rooms with different temperature regime(residential and non-residential).
Roof ladders
The exit is provided by a roof ladder, the movement along which is similar to the movement along the ladder, with the difference that the ladder is located on the surface of the roof.
The ladder may consist of single steps or several steps that make up a single structure. A ladder located along the ridge, as a rule, leads from the hatch structure to the chimney, which makes it easier to clean 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 exits to the roof, and you will be able to carry out all full-fledged work on the roof surface for its long-term operation and safety of residence.
In order to be able to fully control the integrity of the roof, as well as for the purpose of carrying out repair work, convenient and safe access to it should be provided. There are several ways to solve this problem, each of which is selected depending on the slope of the slopes and the type of attic. This article will discuss how to equip the exit to the roof so that it is safe and has no obstacles.
Alternatively, the roof can be equipped with insulated and non-insulated hatches, which will make it easy to get close to any elements of the roof. In addition, you can get to the roof through the attic through the dormers and dormer windows. The number of exits to the roof is determined by its area and building codes. On houses with one floor, the roof of which has an area of \u200b\u200bup to 100 square meters, it may not have exits to the surface.
Exit to a flat or exploited roof
The easiest way to equip an exit to a flat roof is by installing a ladder on outer wall Houses. Its lower step should be placed 1 m from the ground. This will prevent small children from getting on the roof without someone's help. Adults, by attaching a ladder, can easily climb to the roof.
It is worth noting that the steps of the ladder should not slip. To do this, they are made of corrugated steel. In addition, all its metal parts must be opened with some kind of polymer material that prevents them from rusting.
If it is planned to install a balcony or terrace on the top floor, then a stepladder can be placed there as well. Climbing to the roof will be somewhat easier and not as dangerous, but you will need to make your way through the house, which in some cases can be inconvenient.
The device of an external staircase with a slope
A more attractive option would be to use a steep external staircase that will connect the terrace of the lower floor to any platform located at roof level. It not only looks beautiful on the outside - it is also more convenient to use than a stepladder. For its manufacture are used steel pipes, to which brackets are welded for subsequent fixing of corrugated steps. Steps can be made of impregnated hard wood: oak, ash or beech. To facilitate the ascent and descent of the stairs, railings are made of rods, pipes or other materials.
It is worth noting that if funds allow, it is better to make an external staircase from polished stainless steel. This design looks perfect externally, and will last much longer.
Installation of superstructures for access to the roof
To access a flat roof, special superstructures are installed, which are placed above the stairs. They are also called booths - their shape can vary greatly.
They make a superstructure for access to the roof in operation, as a rule, of brick, after which the structure is covered with a roof. An opening is made in the wall for installing 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 the landings of the upper floors is considered universal option roof access devices, both flat and pitched. 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 turns out to be large, then 2 transverse beams are installed between the rafters, after which one is fixed vertically to them. And already to this last bar, one side of the hatch box is attached. If the gap to the rafters is less than the prescribed one, then you will have to make a certain cutout from any rafter leg. After that, the cut edges are fixed with the help of transverse frontal beams to nearby rafters to evenly distribute the load.
It is worth noting that if such access to the roof was not expected 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 interfering with the roof rafter system.
On those pitched roofs that have a large area, and where there are several smokers and other devices that need systematic maintenance, it is advisable to install several hatches. It is important to note that in this case it is not necessary to install running ladders on the roof.
The length of one of the sides of a standard hatch is in the range from 45 to 120 cm. Hatches with other dimensions are made to order, and their price increases by 30%. By design, the manhole covers can open both to the sides and upwards. The lid is held open by gas springs. Hatches, which are produced in series, are equipped with a system of protection 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 quarters with heating must also be insulated. And those that will be placed above the attic, which is used extremely rarely, do not need to be insulated.
Access to the pitched roof through the skylights
Residential attics are equipped with skylights, which are installed in an open under-roof space. They are designed not only for lighting, but also to provide access to the roof. Manufacturers have proposed many models of windows designed for installation on pitched or flat roofs. On roofs with flat slopes minimal slope, it will be necessary to build 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 mounted into it.
According to the requirements, the exit to the roof must be reliably sealed, which is achieved by installing special sealing cuffs. On reverse side cuffs are applied with a special plastic mixture, which will prevent moisture from entering the cracks, and also increase thermal insulation properties hatch. Cuffs are made of copper, aluminum, as well as zinc alloy with titanium.
Application of folding ladders
Exit to pitched roof by means of folding ladders it will allow to disguise the exit and expand the usable area of the room without violating its interior. Thanks to the inner hatch cover, it is possible to hide the entire structure of the stairs. The thickness of the inner covers, taking into account the installation of an insulating layer, can reach up to 66 mm.
Folding stairs are:
- multi-section;
- scissors.
Multi-section ladders are easier to use due to their design. Compared to scissor ladders, they are easier to fold and unfold.
Installation of ladders and steps for the roof
Whatever access to the roof is used, it is better if it is equipped with additional roof steps and ladders. At the same time, it is worth making sure that they are corrugated or perforated. Such special devices will make moving on a sloping roof base easier and safer. It is worth noting that the steeper the design of the slopes, the theme of the steps of the ladders should be placed more often. To make steps, take strip steel 4 mm thick and 40 mm wide.
Please note that the installation of roof drains will provide an opportunity to protect roofing material from mechanical damage, which quite often occur during the maintenance of smokers and other elements on the roof surface.
In order to fix the steps, special fasteners for tiles are used, which have a concrete or aluminum lining. Such a part, together with a step, is attached to the bar with two bolts. After that, the bar 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. Longer 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 are fully versed in all the intricacies of roofing skills can cope with. If the owner seeks help from specialized companies, then in this case he can count on the fact that all technologies in the process of construction will be taken into account, so that the finished structure will be of the highest quality and durable.
To monitor the condition of the roof and carry out repair work, it is necessary to provide a convenient and safe access to the roof. There are several ways to solve this problem, from which the most 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 ladders 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 the dormers 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 \u200b\u200bwhich does not exceed 100 square meters. m, you can not equip access to the roof at all.
Flat roof access
The easiest way to build an exit to a flat roof is with a ladder attached to the outer wall of the house. In this case, the lower step is located a meter from the surface of the earth. This will prevent small children from trying to climb onto the roof on their own. Adults, as necessary, substitute a ladder to the fixed ladder and easily climb up.
No matter how beautiful, durable and reliable your roof is, it will still need inspection and maintenance. You can do such work if it has a special exit to the roof through the hatch. The most important thing is that it be comfortable, reliable and ensure the safety of people on the roof. This article will talk about various options access to the roof with the help of hatches and other systems and passage elements.
The exit device will be determined by the purpose of the attic space 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 arranged inside the house. Helps you reach your goal ladder or a stepladder, which is attached to the hatch inside the house attic floor. From the attic you can get to the roof with the help of a dormer or dormer window.
When talking about a complete set of roofs, it means not only the structure, which includes the base, the material finish coat And drainage system. If you carefully look at it from the side, then, even without professional knowledge, you can notice the antennas and ventilation outlets located on it. In addition to them, on the roof are placed:
- roof hatches;
- valves and fans;
- passing elements;
- skylights;
- chimney pipes and more.
Existing elements of exits to the surface of the roof are of high quality and are modern products. Among their advantages are:
- attractive appearance;
- reliability and durability;
- ease of use;
- harmonious combination with the finish coating;
- ease of installation.
Application of roof outlets
It is necessary to use various exit elements on roofs that need technological and technical inspection of this important construction Houses.
The following construction projects need a technological exit to the roof:
- mansions;
- residential multi-storey buildings;
- preschool and school institutions;
- houses of tape building;
- public buildings;
- non-residential buildings and structures;
- old houses during reconstruction.
A technical access to the roof, provided for antennas and elements of the ventilation system, is required for all buildings in operation, regardless of the type and type of roofing. At present, thanks to a wide range of products, it is possible to select components for technical outlets for the desired finish.
The presence and number of exits to the roof is determined during design work on the installation of the roof.
Methods for accessing the roof
The objects that need technological outputs were listed above. You need to have them when you need to do the following:
- produce repair 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.
Ways to get to the surface of the roof 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 get to it using some devices and objects:
- stepladder installed vertically to the wall;
- vertical outdoor stairs;
- insulated and cold hatches;
- folding ladders;
- roof ladders;
- skylights;
- sliding stairs.
Distinctive features of hatches
Roof hatch in multi-storey buildings residential buildings arrange on the top floor in the ceiling above the last stairwell. IN this option the metal vertical staircase going to it is attached to the floor of the landing, the edge of the hatch and the railing enclosing the landing.
When accessing 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 such sizes of these structures - 45x45 cm and 120x120 cm.
The surface of the roof hatch cover is treated with primer and paints and varnishes. The roofing carpet should have the same appearance over its entire surface, so the manhole cover is lined with the material that is used for the finish coat. In some cases, manhole covers may represent a translucent structure.
It should be borne in mind that when designing such an exit to the roof, SNiP requires compliance with a certain distance between the hatch box and the rafters. The piping of the hatch and the nearest rafter should be at a distance of about 7 cm from each other.
Hatches should open in two directions - up and to the side. Gas springs hold the lid in the open position. For the safety of the residents of the house, 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 attention must be paid to its thermal insulation properties. It is necessary to exit through the hatch opening using a fixed metal structure.
In the case when during the installation of the hatch it is not possible to exactly comply with the design conditions, then another version of it 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 can be attributed to the option in which the exit hatch is located next to the chimney pipe. In this case, it will not be necessary to install additional ladders for the purpose of servicing chimneys.
When the attic is turned into an attic living space, the hatch, in this case, is combined with the window. Non-residential attic spaces have simple non-insulated hatches.
Access to the roof through the roof window
In the case when the attic is used as a living space, then it is quite possible to use a dormer window to access the roof. Today, the production of skylights has been established, both for pitched roofs and for flat ones. They are used for emergency exit to the roof, as well as ventilation of rooms located in the attic space.
With flat roofs, before a skylight is placed, 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, can be different. In most cases, they have dimensions - 66x118 cm, 94x140 cm. All of them are equipped with sealing elements (cuffs) that prevent moisture from entering the interior. Seals simultaneously play the role of 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 box. This will also improve the quality of the seal.
Access to the roof with a ladder
To one of the most simple ways that you can get on the roof is the use of a ladder. It is located vertically along the outer wall. Such access to the roof, the norms of which prohibit the lifting of children, has limitations. The bottom of the structure must be raised above the ground to a height of 1 meter.
The stepladder should have such a surface of the steps that would not be slippery, and, therefore, safe during the lifting of people. They are made from materials such as:
- corrugated steel;
- reinforcement having a sickle-shaped protrusion.
Because the ladder is often on outdoors, for prolongation of its service life the anticorrosive covering is made. It is made using powder formulations or paints and varnishes.
Access to the roof via an external staircase
To exit to a flat roof, instead of a ladder, they often use outdoor stairs. In most cases, its design consists of metal and wooden elements that need 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 wood (oak, ash, beech).
All stairs must be equipped with railings and securely fastened to the walls of the building for safety reasons. Fire escapes made of metal angle or corrugated steel are mandatory in buildings above 2 floors.
Stair structures should be subject to periodic inspection. The strength test is reflected in the documents of the organization serving a particular building. These stairs are used to access flat roof fire brigades.
Climbing to the roof with a folding ladder
The use of folding ladders to access the roof is possible when the hatch has an inner 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 they get to the roof from the interior.
Among the types of folding stairs can be distinguished
- scissor,
- sectional.
With the help of sectional roof ladders, you can safely climb to the hatch and descend. They include several segments. They are more popular than accordion-like scissor designs.
Hatches with an inner cover and folding ladders that provide access to the roof, GOST recommends using them to connect rooms with different temperature, i.e. residential and non-residential.
Use of roof drains
A roof ladder is used to access the roof. You can move along it in the same way as on a ladder. 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 leads, as a rule, towards the chimney. This arrangement facilitates access to the chimneys during their cleaning and other maintenance.
When the slope of the roof is small, the slope steps are set in increments of 70 centimeters. With a roof slope of 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 bars.
Roof ladders made for the movement of a person along pitched roof, have such 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 finish.
If you mount 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 of residents.
