The use of innovative technologies in the production of building materials contributes to the fact that from year to year there is an increasing number of materials that can be used not only by specialists, but also by people far from construction. One of these materials is corrugated board. If you decide to build a country house with your own hands, then you can have no doubts about the choice of roofing material - choose corrugated board. We hope that the video lesson do-it-yourself corrugated roofing video will help you make a decision in favor of corrugated roofing.In our article we will tell you some of the details of the delivery and installation of this material.
In the construction of private buildings and cottages as a roof covering, an increasing number of developers prefer modern roofing profiled sheet. This decision is often made due to the good technical characteristics of the material.
The main characteristics of corrugated board
The professional flooring has many advantages. Let's consider some of them:
- Profiled sheets have a high bearing capacity.
- The material is quite light, so it is easy to work with it.
- When laid, the sheets do not form joints, therefore they reliably protect the roof from all types of precipitation.
- The roof covered with a professional flooring is durable, it does not give in to corrosion thanks to a polymeric covering.
The list of materials and tools necessary for the installation of corrugated board
Do-it-yourself installation of corrugated roofing at first glance is not difficult, but it is important to remember that the construction of a roof is a crucial moment in the construction of any house. Therefore, there should not be any inaccuracies and flaws in the installation of corrugated board.
Advice! Before proceeding with the installation of corrugated board, prepare all the necessary materials and tools in advance and keep them at hand, as it is not recommended to walk on corrugated board.
Transportation of corrugated board
It is important to properly transport the corrugated board to the site.To do this, you need to know that the sheets can only be laid horizontally, it is advisable to pull them together with slings and lay them on a hard surface.
If you neglect this rule, then you can completely and irrevocably spoil the material. It is better to transport corrugated board at low speed, without making sudden braking and turns.
How to properly raise the corrugated board to the roof?
It is necessary to apply corrugated board to the roof in several sheets, using logs.
Important: logs must have a length from the ground to the roof. In windy weather, it is impossible to apply corrugated board to the roof.
Necessary materials:
- Electric shears or a hacksaw (it should be with fine teeth).
- Screwdriver.
- Self-tapping screws.
- Screwdrivers.
The main types of corrugated board
It is important to know: before you make a roof from corrugated board, you need to think about the right step on the crate and choose the corrugated board that will be the perfect cover for the area.
Today, the following types of corrugated board are offered on the market:
- The professional flooring of brand C has a trapezoidal or sinusoidal shape. This type is best chosen for decorative roofing or the construction of a light roof.
- The professional flooring of the RS brand is most often used for mounting walls and roofs.
- The professional flooring of the H brand has additional stiffening ribs. This type can be used for capital roofing and for interfloor ceilings.
How to correctly predict the angle of the roof
Each manufacturer develops instructions for the installation of their products. Important: when buying a material, demand from the seller the instructions attached to the product, it is called like this: installation of a roof from corrugated board instruction.
It is also important to consider the angle of inclination of the roof.This indicator must be known in order to perform the necessary overlap of profiled adjacent sheets.
Consider the options for the angle of the roof:
- At an angle of inclination less than 15 degrees, provide an overlap of 20 cm more.
- At an angle of inclination of 15-30%, the overlap can be 15-20 cm, no more.
- If the angle of inclination is less than 12 degrees or the roof is flat, then additional sealing of the joints and seams with a special sealant will be required. If this measure is neglected, then the roof will not be able to fulfill its functional load and will begin to leak.
If you follow this instruction step by step, then the installation of the roofing corrugated board will be carried out correctly and, accordingly, a high-quality roof will be installed.
Such a roof will delight with its functionality for several decades, without requiring additional repairs and financial costs.
How to properly lay corrugated board
Installation of roofing corrugated board experts advise starting after laying the waterproofing layer. Such a measure will protect the entire truss structure from moisture and condensation. To do this, the waterproofing membrane must be laid on the rafters strictly horizontally.
Important: start laying the hydro barrier from the roof overhang. The membrane must be fixed between the rafters with an overlap of 15 cm without overtightening, using small brackets for fastening. We even recommend leaving a small sag of waterproofing material.
It is necessary to fix the hydro-barrier with the help of a counter-rail. Do not forget to leave some gap between the hydrobarrier and the insulation - it will provide ventilation.
The design of the roof from corrugated board involves the arrangement of the crate. If you decide to use a trapezoidal profile, then it is best to use wooden bars for the crate and follow the crate step - from 90 to 120 cm.
Each type of corrugated board has its own rules for arranging the crate, look for them in the manufacturer's instructions.
After the top end board has been installed above the crate, you need to attach the end strips. Pay close attention to the arrangement of the groove.
You can provide a dense wooden flooring, or you can build it from galvanized steel, overlapping at least 20 cm.
It is important to know: fastening of roofing corrugated board on sloping roofs should be done only after the joints of the groove have been sealed with a special sealing mastic
After that, using self-tapping screws, attach the bottom plank of the groove, first along the edges, and finally fix it when you begin to fasten the roofing. This measure will avoid inaccuracies and curvature.
Before proceeding directly with the installation of corrugated board, carefully read again: roofing corrugated board instructions. So, we begin the installation of corrugated board, and from the lower edge of the roof.
Important: profile sheets must be laid with the necessary overlap (we talked about this above) and fixed on wooden beams with special roofing screws. A feature of these self-tapping screws is that they have rubber seals.
Features of the technology of laying corrugated board on different types of roofs:
- When laying corrugated board on a structure such as do-it-yourself flat roof made of corrugated boardand, its installation must begin from the right end of the roof.
- When installing a hipped roof, the corrugated board must be laid on both sides simultaneously from the highest point of the slope. First, you need to install the cornice strip and fix it with self-tapping screws, after that, a profile-shaped seal must be inserted between the roofing sheet and the eaves strip. Also, do not forget that the cornice strip should protrude 3.5-4 cm beyond the edges of the overhang.
- If the slope of the roof is not too large, then at the longitudinal seams it is necessary to additionally provide a seal or overlap the sheets in two waves.
Some elements of corrugated roofing provide the roof with its reliability. So, on one edge of the profiled sheet there is a gutter.
Important to know: when installing a profile sheet, the profile groove must be located at the bottom of the sheet. Also, when laying a profiled sheet, it must be aligned along the overhang, and not along the joint.
The device of a roof from a professional flooring the instruction contains the following postulates:
- When installing the roofing sheet, temporarily attach it with self-tapping screws at the ridge and at the overhang. Do not forget that the sheet must be lowered over the roof overhang by 3.5-4 cm
- All the following sheets are fixed in the same way.
- Complete fastening of the sheets to each other must be carried out on the crest of the wave in increments of 50 cm in the direction from the overhang to the roof ridge.
- Best for styling SNiP: corrugated roofing.
Only the correct installation of corrugated board will protect the owner of the house from the need to repair the roof from corrugated board.
