How to block the roof with your own hands

Over time, the roof exhausts the margin of strength, and there is a need to replace the coating. To perform a high -quality roof overlap, some professional nuances are required. About how to block the roof on your own, the video at the end of the article will show clearly. The technology of laying hard roofing sheets has general principles.

It is quite possible to block the roof with your own hands. To dismantle the old coating and installing a new roof, at least two people will be required. Before the start of roofing, calculate the roof area and select the appropriate roofing material.

The procedure for dismantling the old roof and preparatory work

The dismantling of the old roof starts from the skate. Roofs of roofing nails are blown up by a mount or nail with a nail. The horse, drainage and other components of the roofs are removed. The upper row of the old roof freed from the nails, tied and smoothly on the cables descends to the ground.

1. The following rows can be dismantled while in the attic. A rafter structure, freed from the old roof, is carefully examined. The damaged or rotten beams of the skeleton are replaced by new ones.
2. Mauerlat, rafter legs, horseback and crate are checked for planar compliance, and are aligned if necessary. A waterproofing film and insulation are installed on the skeleton.
3. The waterproofing film not only protects against condensation, but also prevents the entry of rain and meltwater on the insulation. Modern materials for waterproofing are equipped with a microphorized coating, which provides free circulation of steam and wet air through the attic, thus, the presence of a hydraulic tank contributes to the formation of a dry and “breathing” atmosphere under the roof.
4. A waterproofing film of three layers consists. The average mesh reinforcing layer consists of intertwined plastic fibers. On both sides of which laminating layers and microphorization are applied to ensure free movement of air.

Properly equipped roof with insulation and the entire complex of protective agents, prevents the appearance of icicles and snow lands with a steep pitched roof. To combat landslides, special stoppers are used, they not only break snow layers, but also divide storm streams into small jets.

Arrangement of roofing from metal tiles

Metal tape is modern and practical material. It is made on the basis of galvanized steel and covered on both sides with a protective polymer layer. Light and thin roofs have low thermal conductivity, which contributes to the occurrence of condensate.

1. The blackboard board under a roof of metal tiles is taken 10x2.5 cm in steps 35 - 45 cm. The exact distance of the step is verified depending on the parameters of the roof sheet. Laying a roof of metal tile begins from the edge of the slope. The attached release of the first sheet is 25 - 35 cm.
2. The outer surface of the metal tile is covered with a protective layer of quartz sand. On the horizontal edge, a bitumen adhesive layer protected by a film is applied. After the installation and installation of the roof under the influence of solar heat, the layers of the roof are softened into a monolithic waterproof layer.
3. The tightness of the arrangement of the roof from the metal tile is checked from the attic to the lumen. The gaps and gaps that arose when covering the roof are eliminated using bitumen mastic.

The metal tile imitates a real tiled roof. A wide selection of color scheme and the flexible structure of roofing material allows you to realize any design fantasies and block the roofs of complex reliefs.

Roofing from corrugated board

The profiled galvanized sheet has a metal thickness from 0.4 to 1 mm. The shape and number of stiffness ribs vary depending on the manufacturer and the purpose of the corrugated board.

1. It is advisable to use the roof from corrugated board for direct simple gable or single -sloping flat roofs. The crate is stuffed on the rafter legs so that there are no triggers of the roof sheet. A half -meter step is enough.
2. The corrugations for the roof of the hat, which are selected under the color of the coating in the lower wave of corrugated board, are attached with self -tapping screws. Rubber or plastic washers are installed under the hats of screws. In places of docking, the sheets are recorded by self -tapping screws.
3. The first sheet of corrugated board is exhibited in the lower end part of the rafter skeleton and fixed with self -tapping screws. On it in the direction of the skate, an overlap of 15 - 20 cm is installed the next sheet of the roof and aligned along the edge of the ramp.

The horizontal sheets of corrugated board are mounted overlapping in one wave. The direction of laying sheets from left to right or vice versa, does not matter.

Installation and arrangement of slate roof

The usual asbestos -cement roof has significant weight. Before arranging the roof from the slate, pay attention not only to the crate, but also to racks, struts and rafters. The condition of wood should not inspire fears.

1. For the convenience of installation on the upper crown of the house, an overhang of roof iron or galvanizing is made. The first sheet of slate is attached on the overhangs and fixed with brackets. The following sheets are laid about 20 cm to the skate and fixed with slate nails.
2. The slate nails are made of galvanized iron with large rounded hats. Nails are driven by rhythmic and not strong beats of the hammer into the upper wave of slate leaf.
3. The procedure for laying slate sheets is no different from the installation of corrugated board or metal tiles.

Fastening components for roofing parts

Covered with new roofing material, the roof is equipped with a skate, end strips, end and drains.

1. The horse is selected corner with the desired degree of the discrepancy between the planes or semicircular. The side planes of the ridge overlap the upper joint of the gable roof at least 15 - 20 cm. The horse is attached with self -tapping screws with a step of 25 - 30 cm into the upper wave of the roof of the roof.
2. To protect against gusts of wind and undermining the roof mounts, a end bar is installed. The bar is installed from the ridge to the cornice and is overlapped with a pitch of 45 - 50 cm. The end bar overlaps the cut of the gable roof, preventing blowing under the roof of wind and rainwater.
3. Endova - installed from the inside of the roof along the upper joint of the gable roof. The longitudinal bar of the Endov performs the functions of a moisture removal that fell under the roof. Ends are installed in all places of geometric fractures of the roof. During installation, it is important not to damage waterproofing by self -tapping screws.
4. Hooks are screwed into the cornice board around the perimeter of the house for hanging the gutter. The marking of the hook mounting places is made taking into account the slope for the drain of half a centimeter per linear meter. At the lower point of the drain, a funnel and a drain pipe are attached.

The drain pipe is fixed on the wall of the house, and the lower edge equipped with a knee does not reach the soil level of 20 cm.
