Over time, the roof exhausts the safety margin and there is a need to replace the coating. To perform high-quality roof overlap, compliance with some professional nuances. On how to overlap the roof yourself, the video at the end of the article will show clearly. Technology laying hard roofing sheets has general principles.

It is quite realistic to overlap the roof with your own hands. To dismantle the old coating and installing a new roof, no less than two people will be required. Before the start of roofing work, calculate the roof area and choose a suitable roofing material.
The order of dismantling the old roof and preparatory work
Dismantling the old roof begins from the skate. Mounted or nail-holder is undermined for broad hats roofing nails. Duck, drainage chute and other component roofs are removed. The top number of old roofs liberated from nails, is tied and smoothly descended on the ground.
- The following rows can be dismantled while in the attic room. The skeleton of the rafting construction liberated from the old roof is carefully examined. Damaged or rotten skeleton beams are replaced by new ones.
- Maurylalat, rafter legs, a hat and a doomer are tested on a plane matching, and if necessary, aligned. The skeleton is installed a waterproofing film and insulation.
- The waterproofing film not only protects against the occurrence of condensate, but also prevents the incidence of rain and melting heat. Modern materials for waterproofing are equipped with a microporphorized coating, which provides free circulation of steam and wet air through an attic room, thus, the presence of a hydrocker contributes to the formation of a dry and "breathable" atmosphere under the roof.
- It consists of a waterproof film of three layers. The average mesh reinforcing layer consists of intertwined polyethylene fibers. On both sides of which laminating layers and microperphoration are applied to ensure free air movement.
It is properly equipped with a roof with insulation and a whole complex of protective agents, prevents the appearance of icicles and snow landslides with a steep pitched roof. Special stoppers are used to combat landslides, they not only break the snowy layers, but also divided into small jets of storm flows.
Arrangement of the roof of metal tile
Metal tile - modern and practical material. It is made on the basis of galvanized steel and covered on both sides by a protective polymer layer. Easy and thin roof has low heat resistance, which contributes to the occurrence of condensate.
- The board of the crate under the roof of the metal tile is taken by 10x2.5 cm in a step of 35 - 45 cm. The exact distance of the step is evaporated depending on the roofing sheet parameters. Laying the roof of metal tile starts from the edge of the skate. The first sheet of the first sheet is 25 - 35 cm.
- The outer surface of the metal tile is covered with a protective layer of quartz sand. The horizontal edge causes a bitumen adhesive layer protected by film. After mounting and installing the roof under the influence of solar heat, the layers of the roof are sintered into a monolithic waterproof layer.
- The tightness of the arrangement of the roof from the metal tile is checked from the attic room on the lumen. The gaps and gaps arising from the roof covering are eliminated using bitumen mastic.
Metal tile imitates a real tiled roof. A wide selection of color gamut and a flexible structure of roofing material makes it possible to implement any design fantasies and overlapping the roofs of complex reliefs.
Roofing from Profile
The profiled galvanized sheet has a metal thickness from 0.4 to 1 mm. The form and number of ribs rigidity vary depending on the manufacturer and destination of the professional flooring.
- The roof from the corrugated floor is desirable to use for direct uncomplicated two-tight or single-sided flat roofs. The cutture is stuffed on the rafting legs in such a way that there are no roofing sheets. Step half meter is quite enough.
- Major braified with self-draws for the roof of the hats, which are selected by the color of the coating in the lower wave of professional flooring. Under the screws of the screws are installed rubber or plastic washers. In places docking, the sheets are fixed by self-drawing.
- The first sheet of professional flooring is set at the lower end part of the rafter skeleton and is fixed by self-drawing. On him in the direction of the skate of the Machine 15 - 20 cm, the next sheet of roof is installed and aligned along the edge of the skate.
Horizontal sheets of professional flooring are mounted in a shaft with a step in one wave. Direction of laying sheets from left to right or vice versa, no values.
Installation and arrangement of slate roofing
The usual asbestos cement roof has a significant weight. Before arranging the roof of the slate, pay attention not only to the crate, but also on the racks, soils and rafters. The state of wood should not inspire concern.
- For the convenience of mounting on the top crown of the house there is made of roofing iron or galvanized. The first slate sheet is attached to the atmosphere and fixed with brackets. The following sheets are stacked in approximately 20 cm to the skate and fixed with slate nails.
- Slaft nails are made of galvanized iron with large rounded hats. Nails are driven by rhythmic and not strong hammer blows into the top wave of slate sheet.
- The order of laying slate sheets is no different from the installation of professional flooring or metal tile.
Fastening components for roofs
Located with new roofing material, the roof is equipped with a skate, end straps, end and drainage.
- The horse is selected by the corner with the desired degree of discrepancy of planes or semicircular. The side planes of the skate overlap the upper joint of the bartal roof is at least 15-20 cm. Boots bumps with screws with a step 25 - 30 cm into the top wave of the roof crest.
- To protect against the winds of the wind and undermining the roofing fasteners, an end plank is installed. The bar is installed from the skate to the eaves and mounted a mustache with a pitch of 45 - 50 cm. The end plate is overlapped with a duplex roof section, preventing strangling under the roof of wind and rainwater.
- Endow - is installed from the inner part of the roof along the top joint of the bartal roof. The longitudinal plank of Endov is performs the functions of the moisture drop in the roof. UNDOVES are installed in all places of geometric roof fuses. When installing, it is important not to damage the waterproofing by self-draws.
- In the cornice board around the perimeter of the house, hooks are screwed for hanging the drainage gutter. The markup of the places of fastening of hooks is made taking into account the slope for the waterproof of the half-meter on the traffic point meter. At the bottom point of the drain attached a funnel and a drainage tube.
The drain tube is fixed on the wall of the house, and the lower edge, equipped with the knee, does not reach the level of soil 20 cm.
