It is difficult to imagine roof care, gutter cleaning, antenna repair, solar collector maintenance, chimney renovation or chimney cleaning without access to the roof, a good solution will also be appreciated by a chimney milling company. The choice of the method of access to the roof depends on the angle of inclination of its slopes and the purpose of the space below it. Access to the roof is provided by a wooden vertical ladder or externally mounted, a folding ladder with wooden treads, an internal ladder with a hinged cover, as well as various types of roof exits – insulated and non-insulated. Steps and ladders installed on the roof make it easier to move comfortably on the roof. The road to the roof must be reliable.

Ladder on the wall (variant for flat roofs)
The simplest solution is vertical, reinforced on the outer wall. The bottom edge of the ladder should be about 1 m from the ground, this will prevent children from climbing to the roof, and adults can use a regular ladder in this case. A similar solution is the sectional staircase, consisting of two parts. Its lower part is about 1.5 m high, it is used when necessary.
It is important that the surface of the stair treads is not slippery. To do this, they are made of corrugated steel or periodic profile rebar (with sickle-shaped protrusions).
A ladder mounted on the floor wall, leading to the roof from the balcony or terrace, is safer. The only drawback is that you have to go through the interior of the house to get to the roof. Stairs made of metal structures must have an anti-corrosion coating with paints and varnishes or compositions of polymer powders.
Exterior Stairs (For Flat Roofs)
More comfortable and visually attractive compared to wooden vertical stairs are steep external stairs, which lead from the lower floor to the terrace (or landing) located at the level of the roof supported by rafters (good rafters – Sawmill Strzybnica). The structure of such a staircase is made of a steel pipe with brackets welded to it – for mounting steps. Their steps are made of corrugated sheet metal or impregnated wood (oak, beech, ash). And the railing can be made of pipes, rods, etc. Usually, the surfaces of all steel elements of the stairs are protected against corrosion with paints and varnishes. But such a ladder can be made of polished or brushed stainless steel.
The components of the metal ladder leading to the roof can be coated with polymer powder or stainless steel compositions.
Use
Usually, roof hatches are placed above the upper landing of the staircase. The location of manholes in pitched roofs depends on the slope of the rafters. The distance between the manhole box and the adjacent rafters to which it is attached should not exceed 7 cm, if this gap is larger, two cross beams and one vertical beam should be installed between the rafters (one of the sides of the manhole box). When the roof hatch is wider than the distance between the rafters, cut a section of the rafter leg and reinforce its cut edges to the transverse end beams transferring the load to the adjacent rafters. On a sloping roof with a large area with several chimneys, it is better to install two roof hatches. Then there will be no need to use escalators for the chimney sweep. The hatches should be located next to the chimney. There are several sizes of manholes available on the market: the smallest – 45 x 55 cm, the largest – 120 x 120 cm It is also possible to order a custom-made manhole. But the price of such a hatch will be 20-30% higher than the cost of a mass-produced hatch of similar dimensions. The chimney casing is usually finished with a galvanized steel roof, its surface is primed and covered with paints and varnishes or powder varnish. Then there will be no need to use escalators for the chimney sweep.
To prevent the chimney cap from being visible on the roof surface, it is lined with the material used to make the roof. It is easier to finish the chimney covering on the roof made of bituminous shingles or steel sheet. But it is better to entrust it to a professional roofer who will do the job better. The lid can be transparent, filled with glass or polycarbonate. The hatch opens upwards or to the sides. In the open position, the cover can be fixed with two cylinders (gas springs). Mass-produced manholes are equipped with devices that prevent uncontrolled closing of the cover. If the manhole is installed above a heated room (stairs, dressing room, utility room), its thermal insulation properties are of great importance. Some manufacturers offer insulated roof hatches, the structure of which can have resistance to heat transfer R=1.5m2K/W (the polycarbonate lid has R=0.45m2K/W). The sleeves supplied with the manholes allow them to be installed in roofs with a layer of various materials, both flat and corrugated, having both regular waves and high profile waves.
Sometimes roof hatches are equipped with anti-burglary protection, their cap is additionally reinforced from the inside, and the hinge pins will not allow them to be removed with the cover closed. The manhole can be equipped with a lock grille located at the bottom of the manhole box. It is possible to order a hatch with a three-bolt lock with a bolt or with a bolt equipped with a certified lock cylinder.
Roof Treads and Ladders (Suitable for pitched roofs)
The freedom of movement of people on the surface of the sloping roof is ensured by steps and ladders mounted on the roof. On roofs with a slope of less than 30°, the steps should be installed at a distance of 70 cm between them (in every second row of tiles). If the slope of the roof slope is greater than 30 °, the steps are installed 35-40 cm each (in each row of tiles). Escalators are usually 25 cm wide and 40 to 300 cm long.
The step base is made of a flat steel bar (40 x 4 mm) and the handle is made of 2 mm thick steel sheet. On the steps located in every second row of tiles, they move like a ladder. A long ladder along the ridge serves as a horizontal path leading from the manhole to the chimneys. The steps and platforms of navigation ladders are made of galvanized steel sheet, the surface of which is varnished or powder coated in color. Roofing.
Steel stairs do not always blend in visually with the roof, as bitumen shingles do. An alternative to a typical metal ladder is a platform ladder made of pressure-impregnated wooden rods with a cross-section of 40 mm. These bars are attached above the brackets at the base of the stairs. The base of the stairs and steps can be supported by rods attached to the rafters with bolts. Basic supports are selected depending on the type of roofing: ceramic tiles, cement tiles, metal roofing tiles, flat or profiled steel roofs, roofing or bituminous shingles.
The distance between the ladder consoles must not exceed 80 cm. If the chimney is high, brackets are installed that rise to its mouth.
Wooden and steel steps and ladders must have a corrugated or perforated surface to prevent slipping
For the installation of steps on the roof, special tile elements with aluminum or concrete cladding are used. These elements are selected depending on the type of tiles used in the roof. A single-step tile element is attached to the beam with two screws (e.g. 4.5 x 45 mm) and the beam is fixed to the rafters with nails.
Types of roof exits
The most common design solutions are the following options:
- Horizontal. It is used in situations where it often needs to be lifted to the attic. You can do this yourself by cutting out the ceiling and installing a ladder.
- Vertical. It is suitable for multi-storey buildings. If one of the rooms does not have an attic and is connected to the roof. Such a hatch is built into the wall that separates the living and non-residential spaces. Very rarely used in private construction.
- Strych. Właz połączony z wejściem na dach. Projekt trudny do zrealizowania, który zazwyczaj trafia do wyspecjalizowanych pracowni. Funkcjonalne i dobre rozwiązanie dla domów z poddaszem użytkowym.
- Rewizja. Przy niewielkich spadkach połaci dachowych trudno jest wejść na strych. Jeśli nadal musisz sprawdzić przestrzeń nad pokojami, zrób mały właz. Zwykle używa się drabiny składanej lub przenośnej.
- In the classic version , access to the attic is a square with a white sash. If you want, you can make or order a design that matches the color of the interior of the house. Large dormers are equipped with two wings, and in some cases, it is enough to tilt half of the hatch to enter the attic.
If the attic is not heated, you should take care of the proper insulation of the house. Ready-made options are sold in stores, so there is no need to calculate the thickness of insulation and install a manhole.
