Do-it-yourself corrugated roof. Installation of the end overhang assembly, ridge assembly and junction bar. Forming the adjoining of the roof to the wall

Properly performed installation of roofing will protect your home from leaks and collapses, providing a comfortable and cozy stay. Today, most specialists opt for an environmentally friendly product, which, moreover, guarantees the durability of the roof - this is corrugated board. For those who doubt, we recommend watching: do-it-yourself corrugated roof video. We hope that after watching the video tutorial, you will finally be convinced of your own abilities and proceed with the installation of the roof from corrugated board on your own.

If you have decided to do the installation of a corrugated roof with your own hands, then initially you need to measure all the necessary dimensions of the roof.

A little advice: when measuring the roof, be sure to keep in mind that the edge of the sheet of material will protrude 40-50 mm beyond the edge of the eaves.

There are a huge number of options for how to install a roof with corrugated board today. Familiarize yourself with them in the product catalog, only then choose the one you like best.

Expert advice: when buying corrugated board, it is better to order its sheets, the length of which will cover the entire roof from the ridge to the eaves. At the same time, do not forget that to connect the sheets to each other, you still need to add 40-50 mm, then the quality of the roof will be much higher.

But, if the roof is too long, then before you raise the corrugated board to the roof, in order to make it convenient to transport and install, divide the large sheets into parts.

The main stages of the technology of installation of corrugated roofing

Despite the fact that do-it-yourself roofing with corrugated board has a simple installation technology, nevertheless, you do not need to relax and carefully follow all the recommendations from the instructions for corrugated board step by step.

Expert advice: be sure to ask the seller for instructions. Know: every manufacturer is interested in having more people buy his products.Therefore, a certified product always has an installation manual, especially since such a product is guaranteed to be reliable and of high quality.

So, step number 1 - waterproofing

Neglecting waterproofing is more expensive for yourself. Properly executed waterproofing will protect the roof and the whole house from condensate formed when the ambient temperature changes.

Buy waterproofing material in hardware stores, you will be prompted by its parameters and properties. It is necessary to place the waterproofing material even before installing the roof between the rafters on the roof sheathing.

A little tip: lay the waterproofing material with a slight sag perpendicular to the slope.

Important: observe a uniform step on the crate, sheets of corrugated board will be attached to them.

Step #2 - Ventilation

The simplest option for arranging ventilation is to place wooden slats directly on the waterproofing layer.

Experts do not recommend neglecting the arrangement of ventilation, since a certain amount of moisture will still fall between the roof and waterproofing.

Step number 3 - installation of corrugated board

Before you make a roof from corrugated board, carefully read the instructions for its installation again.

Scheme of installation of corrugated board

So, at the level of the crate under the valley plank, make a dense flooring of boards on both sides not at a distance of 60 cm from the groove. Moreover, the bottom boards of the valley must be installed with an overlap of 200 mm, no less.

First, attach the bottom plank with a few nails from the edges, finally fix it at the same time as the entire roof.

A little advice: if the roof slope is gentle, then use sealing mastic.

We install the bottom (lower) bar of the valley. To do this, its upper ridge must be bent over the ridge of the roof or made a flanging.

Remember: the bar must go under the ridge by 250 mm or more. Between the corrugated board and the bottom plank of the valley, it is best to install an additional profiled or universal seal.

When installing a rectangular-pitched roof, experts recommend starting the installation of a corrugated roof only after installing the end boards. So it is much more convenient and easier to stir sheets of corrugated board on the roof.

Moreover, the end top board must be installed above the crate, since further it will be necessary to attach the end plate to it. Thus, you will equip the so-called wind corner.

Installation of the end overhang assembly on the roof

The filing of the roof with corrugated board begins after the cornice strip is installed. It can be attached with both nails and screws.

Important: the cornice strip must be lower than the waterproofing carpet. Only then will the condensate, which rolls down the waterproofing, fall onto the cornice strip and, breaking off from it into the catchment area, falls onto the blind area or simply onto the ground.

In the case when the cornice strip is under the corrugated board, it is necessary to additionally provide ventilation of the under-roof space.

This measure helps to remove water vapor. Also, under the corrugated board, in this case, it is not superfluous to install a seal (it must be breathable).

Cornice overhang: device option

The drainage gutter, which is on the corrugated board, must be covered with a subsequent sheet. Moreover, installation can be done both from left to right and from right to left. In fact, the sheet must either be superimposed on the previous one, or slipped under it.

When covering the roof with a corrugated flat roof, use a sealing longitudinal gasket and overlap the sheets in one wave.

In the case when the gasket is not used, it is better to overlap in two waves. When installing steep slopes, the longitudinal seal can be omitted, the overlap should be done on one wave.

The structure of the corrugated roof predetermines the laying of profiled sheets. So, on a gable roof, it starts from the end of the roof.

When installing a hip roof, the laying of the flooring begins from the center of the hip.

Important: align the sheets along the cord, which is pulled along the eaves. Many mistakenly align to the end of the slope.

We offer you to view the roof from corrugated board video. After reviewing it, you will be convinced that the sequence of installation of corrugated board is identical to the sequence of installation of metal tiles.

At the same time, one should not forget that the cornice overhang should be 35-40mm. When installing the first roofing sheet, temporarily fix it with a screw in the center.

Lay 3-4 more sheets in the same way. Between themselves, the roofing sheets can be connected at the crest of the wave using self-tapping screws for the roof (their size is 4.8 × 19 mm), performing a uniform step of 500 mm. Only after you align the sheets along the line of the roof overhang, you need to finally fix them.

Attach roofing sheets on the ridge and at the overhang through the bottom of the profile to the crate, fastening in every second wave. At the end, fasten along the bottom of the profiled sheet to each lath.

Depending on what thickness of corrugated roofing is used, you need to fix the middle part of the sheet in a checkerboard pattern: screw 4-5 screws into each square meter.

Methods for laying profiled sheets in multi-row laying:

1. Vertical laying. The first sheet is laid on the bottom row, temporarily attached. Then the first sheet of the second row is laid in the same way. Then the second sheet is laid on the first row and the second sheet on the second row. A whole block consisting of 4 sheets comes out. Repeating the previous sequence, the next block is docked. This method is best used when you need to close the roof with corrugated board with a drainage (drainage) groove.
2. In the second version, the block consists of 3 sheets: two sheets are stacked on the first row, fastened together, one sheet of the second row is attached to them and docked. The block is finally fixed after it is aligned with the cornice. After that, they begin to fasten the same block of 3 sheets. This installation option is suitable for sheets that do not have a gutter.

Covering the roof with corrugated board - the video will convince you of the correctness of the actions. We draw your attention to the fact that profiled sheets are quite light, therefore, high loads are strictly prohibited, including walking on a roof made of corrugated board.

How to properly install the end and ridge trim?

The end plank should have a length of 2 m; when building up 50-100 mm, it is necessary to overlap the planks one on another.Experts recommend laying end strips from the side of the roof overhang, directing them to the ridge.

If there is an extra length, then at the ridge it can be easily cut off. The end plank must cover at least one wave of the roofing sheet. The bar is attached not only to the end board, but also to the profiled sheets using self-tapping screws, following a step of no more than 1 meter.

To mount the ridge strip, it is better to use ridge smooth elements. Between them and sheets of roofing material that have trapezoidal profiles, we recommend laying an additional ventilated seal.

If the sheets have a fine corrugation, then lay the ridge seals.

Installation of the ridge knot

Ridge planks should be laid with an overlap of 100 mm or more. Fasten them to profiled sheets with self-tapping screws, in increments of up to 300 mm.

Mounting the junction bar

The length of the junction plank is 2 m, the planks must be laid with an overlap of 200 mm or more. On the side where the junction bar joins the roofing sheets, we fasten it with 4.8 × 19 mm self-tapping screws, performing a step of at least 400 mm.

Fastening to the wall must either be hidden under its lining or performed using a strobe.

Making the junction of the roof to the wall

The construction of a corrugated roof requires special care and step-by-step instructions.

So, in order to connect the end of the roof to the wall, a ridge seal is used. It is laid between the joint strip and the upper edge of the corrugated sheet.

When the sloping roof is attached to the wall at the side, we recommend using a longitudinal seal. This measure will protect against clogging of cracks with snow. When installing a steep roof, this measure is inappropriate.

In our article, we talked about the fact that it is quite possible to cope with the installation of a corrugated roof on our own, for this you need to get acquainted with some of the rules and secrets of its installation.
