How to properly lay corrugated board on the roof

Roofing is a responsible matter and requires full compliance with technological nuances. On the Internet there is a detailed description of how to properly lay corrugated board on a pitched roof. Let's talk about the features of the process, possible errors. You can choose high-quality roofing products in the Almet online store. A large assortment, individual selection will allow you to purchase exactly what you need.

Which side to join the corrugated board?

If a galvanized profiled sheet is used, then both sides are the same. For polymer analogues, the front side is considered to be the side that is painted in a certain color. The left and right side borders end with different edges. As for the joints, the correct connection is considered to be one where a wave is on top, the edge of which is bent down. This ensures that there are no leaks and maximum protection against moisture ingress into the under-roof space.

How much should the corrugated board on the roof protrude?

The optimal size of the cornice overhang is 35-40 mm. This is a regulated norm. The main function of the overhang is to protect the walls of the house from slanting rain, the removal of melting snow at a certain distance from the basement of the building.

How to fix corrugated board on a shed roof?

General mounting points include:

• overlapping vertical stripes;
• docking of the 1st and 2nd rows to a width of at least 10 cm;
• fixation along the lower edge (on the cornice) in each wave, namely in the middle of the depression;
• the size of the overlap is determined by the angle of the roof slope;
• to align the sheets by means of an overhang.

After finishing work on one side of the roof, move on to the other. At the end, finish the skate with additional elements.

What should be the overlap of the corrugated board?

Sheets are mounted with partial overlap. The size of the overlap is determined by the steepness of the roof. What recommendations should be followed:

• if the roof slopes no more than 15°, an overlap of 20 cm is sufficient;
• for an angle of 15-30, the parameter will change down (15-20 cm);
• when the slope is over 30 °, it is necessary to join adjacent sheets with an overlap of 10-15 cm.

By adhering to these parameters, you will ensure sufficient tightness of the future design.

Proper laying of corrugated roofing how to do it right

The key to a reliable roof is the observance of laying technology. It is recommended to watch a training video on how to properly lay the corrugated board on the roof. This is a visual instruction that will demonstrate the installation process better than any words.

Let's describe the general steps:

1. Safe transport of material to the roof with homemade lags.
2. Accounting for overlap in a particular case.
3. Reliable fixation of the flooring with the help of special self-tapping screws.
4. It is necessary to measure the dimensions of the cornice overhang.
5. If the laying is done in two rows, then the sequence is as follows: the sheets are placed vertically. The first is in the lower corner of the roof end, the second is on top. Fix to the crate. Next, the lower one is attached in the 1st row, then the upper one in the 2nd row.
6. Do not forget about additional elements and design of the ridge.
7. After work, the roof is cleaned of debris. Fasteners can be sprayed with anti-corrosion liquid.

With the appropriate skills, the availability of a tool, operations can be performed without the involvement of a professional team.

Rules for choosing a brand of corrugated board

When choosing, we focus on the following characteristics:

• profile mark. The optimal steel thickness for private construction is 0.5 mm. Suitable profiled sheet type NS with a corrugation height of 35-60 mm;
• type of coverage. It is better to use materials with a polymer layer. Large selection of colors. Reliable protection against corrosion and other factors;
• sheet length. Choose products from 3 to 7 m;
• additional structural properties capillary groove, reinforcement with stiffeners, profile geometry, corrugation repetition period;
• weight;
• unit cost.

To make an informed decision, it is advisable to consult with experts.

Features of mounting sheets of corrugated board

Installation work is carried out in stages. Before laying the flooring, it is necessary to carry out a number of preparatory work:

1. Lathing installation.
2. Laying boards under valleys, drains and other roofing elements. The size and shape must correspond to the additional components.
3. Fixing side boards from the end of the building.
4. Installation of a roofing pie. Layers are stacked one after another, starting from the interior decoration of the house. Vapor barrier (done with a slight sag of the film to organize ventilation), selected insulation, waterproofing layer, control lathing, lathing.

The next step is direct installation of the roof.

Fastening and laying profiled sheets on the roof

To begin with, it is important to read the instructions on how to properly lay the corrugated board on the roof. Tools, personal protective equipment, fasteners are prepared in advance. The lifting of the material is carried out by means of construction lags.

Laying to produce transverse belts. Fasten corrugated steel to the crate in several places along the perimeter, in the middle, at the joints. Along the eaves, self-tapping screws are screwed into each depression. Make an overhang of about 35-40 mm. The screws should enter the base perpendicularly with a moderate amount of tension. For each sheet you will need 6-8 fasteners. Observe the overlap between rows (10 cm) and at the joints with adjacent parts.

How to lay a professional sheet on the roof with your own hands

The do-it-yourself roof installation scheme is simple and straightforward. First you need to choose the side from which you will begin the coating. Next, begin to fasten according to the scheme 1 sheet of the bottom row, 1 sheet of the top, 2nd at the bottom, third at the top. You can also first lay 3 sheets at the bottom, then 4 and 5 at the top. In both cases, geometric accuracy is checked using a plumb line stretched along the eaves. Having finished both slopes, they decorate the ridge, snow holders, ebbs, corner strips with additional components.

If you want to know how to properly lay the corrugated board on the roof of the garage, then the process is similar to installing the roof of a private house. The only difference is in the type of material. You can choose the usual galvanized version. Since the roof area is small, it is possible to cover in one row. With metal scissors, you can cut the material to individual sizes.

Technology for fastening corrugated board to the roof

Here are the main technological processes that you should pay special attention to:

• choice of overlap, taking into account the angle of inclination of the slope;
• correct fastening and docking;
• use of suitable screws;
• for trimming the use of scissors for metal;
• reliable insulation of the structure;
• laying insulating materials before installing the flooring.

If you disassemble the process point by point, then everything becomes very clear. To purchase the desired version of the profiled material is available from Almet.
