How to cover the roof metal tile

How to cover the roof metal tile Metal — today one of the most popular materials used for the construction of the roof. Among other advantages it — ease of installation, allowing homeowners to cover the roof yourself. However, in order to make this work properly, you must still have certain knowledge and skills. We hope our article will help you to form an idea of ​​how the installation of metal.

Metal usually cover pitched roofs with a simple geometry and slope of 14 degrees. If the roof is made up of straight surfaces, but has at the same complex form, it is possible to cover the metal tile, but the material would have to be cut. The result will be a lot of scraps and spending on the purchase of the material will increase.

So, first you need to purchase a sufficient number of sheets of material. For this it is necessary to measure the length and width of the roof slope. The length of the sheet metal must be 4 cm longer than the slope of the roof, because the sheet is fixed to the upper base of the roof so that one side is overlapped cornice. Thanks to this arrangement of the material on the ridge creates a ventilated space. The last thing you want to measure roof slopes diagonally to make sure that the roof has the correct geometric shape. If the roof slope has distortions – they need to be corrected. If the correction of defects of the roof is not possible, then the laying of metal will have to do so that the bottom edge of the batten coincided with the line of the eaves sheets of material.

To lay the metal, you will need special tools: metal scissors, hacksaw, electric saw, electric drill and other roofing tools. Take care of their purchase in advance.

Rafter system called « the skeleton of the roof ». It must withstand the wind gusts, the weight of the roof and the snow accumulating on the roof, so, according to the modern requirements, the roof must withstand a load of 200 kg per 1 sq. meter regardless of the weight of the roofing material. Incorrect installation of the roof system could lead to the collapse of the roof, so the construction of the rafters can not make mistakes. Before the installation of truss system, it is necessary to align the surface of the load-bearing walls tie, then put waterproofing mauerlat (longitudinal beams) and sill. Next, you need to collect from the girders, columns and struts podstropilnuyu support system. This system will take on the weight of truss system. Next set rafter – first the extreme and then the intermediate.

The roof was never put directly on the rafters, so you first need to install the crate. Crate is performed either from metal profiles or wooden planks – the second option is more often used. Batten boards are attached to the rafters with nails. Lathing parameters (width planks, the distance between them, etc.) depend on the choice of roofing material. To take the crates under the metal board width of about 100 mm. The thickness of the boards may vary and is normally calculated by experts who design the roof. The thickness of the boards lathing, overlooking the eaves, must be less than the thickness of the remaining boards about 10-15 mm. The distance between the boards must be equal to the cross-step profile (350 or 400 mm), though the distance between the ledge overlooking and the accompanying board must be less than the standard distance of 50 mm (ie, it will be 300 or 350 mm).

How to cover the roof metal tile Sheet metal fastened to the furring. If the roof gable, then start from the end of the installation, if the roof is hipped – Sheets is first secured to the highest point, and then slowly lowered on all sides of the roof. Each sheet metal should be covered in the following list. The sheets are attached to the roof ridge using screws and connected to each other with screws.

Socket strips mounted from the bottom up on the pediment, while covering the edge of the sheet metal. End slats fastened with screws to the bottom of batten and to extreme waves sheet metal. After placing all the sheets and end brackets are installing ridge bars. These strips are attached with screws to the upper point of the wave of metal (for each second wave). When installing the strips along the length of the overlap should be 10 cm.

Installation is performed valley at the junction rays. The lower valley is installed on top of the crate Cornice strip and the upper valley – sheet metal on top of the wave. Installation of the drain system (pipes, gutters and hooks) must be done according to the manufacturer of the system. Note: the hooks for attaching gutters must be installed on the crate to the installation of sheet metal.

Installation of the drain system is one of the final operations of stacking sheets of metal. These operations also include the installation of safety features and maintenance of the lightning protection of the roof.
