How to cover the roof with your own hands

Over time, the roof exhausts the safety margin, and there is a need to replace the coating. To perform high-quality roof overlap, certain professional nuances are required. On how to block the roof yourself, the video at the end of the article will show clearly. The technology of laying rigid roofing sheets has general principles.

It is quite possible to cover the roof with your own hands. At least two people will be required to dismantle the old covering and install a new roof. Before the roofing work, calculate the roof area and select the appropriate roofing material.

The order of dismantling of the old roof and the preparatory work of

The dismantling of the old roof begins from the ridge. Mounting or nailing undermine for wide hats roofing nails. The horseshoe, gutter and other components of the roof are removed. Released from the nails of the upper row of the old roof, tied and smoothly on the cables descends to the ground.

1. The following rows can be dismantled while in the attic. The skeleton of the rafter structure, freed from the old roof, is carefully inspected. Damaged or rotten skeletons are replaced with new ones.
2. Mauerlat, rafter legs, skate and lath are checked for flat alignment, and if necessary aligned. On the skeleton is installed a waterproofing film and a heater.
3. Waterproofing foil not only protects against condensation, but also prevents rainwater and melt water from entering the insulation. Modern materials for waterproofing are equipped with a microperforated coating, which ensures free circulation of steam and moist air through the attic space, thus, the presence of a hydrobaryar promotes the formation of a dry and "breathing" atmosphere under the roof.
4. Consists of a waterproofing film of three layers. The middle mesh reinforcing layer consists of intertwined polyethylene fibers. On both sides of it are laminated layers and microperforation to ensure free air movement.

Correctly equipped roof with insulation and the whole range of protective equipment, prevents the appearance of icicles and snow landslides from a steep pitched roof. To combat landslides, special stoppers are used, they not only break the snow layers, but also divide the torrents into small streams.

Roofing from metal roofing

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

1. The board of the roof under the roof made of metal tiles is taken 10x2.5 cm in increments of 35 - 45 cm. The exact step distance is verified depending on the parameters of the roofing sheet. The laying of the roof from the metal tile begins from the edge of the ramp. The hinged output 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. The bitumen adhesive layer is protected by a film along the horizontal edge. After installing and installing the roof under the influence of solar heat, the roof layers are sintered into a monolithic waterproof layer.
3. Tightness of the arrangement of the roof from metal tiles is checked from the attic to the lumen. Slots and gaps, which arise when the roof is closed, are eliminated with bitumen mastic.

Metal tile imitates a real tiled roof. A wide range of colors and flexible structure of roofing material allows you to realize any design fantasies and cover the roofs of complex terrain.

Roofing of profiled sheeting

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

1. Roof from corrugated board is desirable to use for straight simple gable or single-pitch flat roofs. The lining is packed on the rafter legs in such a way that there are no deflections of the roofing sheet. A step in a half-meter is enough.
2. The corrugated board is equipped with self-tapping screws for the roof of the bonnet, which are selected for the color of the coating in the lower wave of corrugated board. Under the hats of self-tapping screws, rubber or plastic washers are installed. In places where the lap joints overlap, the sheets are fixed with screws.
3. The first sheet of corrugated board is exposed in the lower end part of the rafter's skeleton and is fixed with screws. On it in the direction of the ridge overlap of 15 - 20 cm, the next sheet of roof is installed and aligned along the edge of the ramp.

Horizontal sheets of corrugated board are lapped in one-wave increments. The direction of laying the sheets from left to right or vice versa does not matter.

Installation and construction of slate roofing

Conventional asbestos-cement roofing has significant weight. Before the construction of the roof of slate, pay attention not only to the crate, but also on the racks, struts and rafters. The condition of the wood should not cause concern.

1. For easy installation on the top crown of the house is made overhang of roofing iron or galvanized. The first sheet of slate is attached to the eaves and fixed by staples. The next sheets are laid in overlapping approximately 20 cm to the ridge and fixed with slate nails.
2. Slate nails are made of galvanized iron with large rounded hats. Nails are driven by rhythmic and not strong blows of the hammer into the upper wave of the slate sheet.
3. The order of laying slate sheets does not differ from the installation of corrugated board or metal roofing.

Fastening of accessories for the roof

Covered with new roofing material, the roof is equipped with a ridge, end slats, end and gutters.

1. The tail is selected with the angular with the required degree of divergence of planes or semicircular. The side planes of the ridge overlap the upper joint of the gable roof by no less than 15-20 cm. The skate is fastened with screws in increments of 25-30 cm to the upper wave of the crest of the roof.
2. For protection against gusts of wind and undermining of fastenings of a roof the end bar is established. The bar is installed from the ridge to the cornice and is lapped in steps of 45 to 50 cm. The end plate overlaps the slope of the gable roof, preventing wind and rainwater from blowing under the roof.
3. Endowa - installed from the inside of the roof along the upper joint of the gable roof. The longitudinal strip of the valley has the function of removing the moisture that has fallen under the roof. The Endovs are installed in all places of geometric fractures of the roof. When installing, it is important not to damage the waterproofing with self-tapping screws.
4. Hooks are hung into the cornice board along the perimeter of the house to suspend a gutter. The marking of the fixing points of the hooks is made taking into account the slope for a drain of half a centimeter on the running meter. At the bottom point of the drain, a funnel and a drain pipe are attached.

The drainpipe is fixed to the wall of the house, and the bottom edge, equipped with a knee, does not reach the ground level of 20 cm.
