Preparation of the roof structure to put a new cover usually takes up to 70% of the time spent on implementation of the new coverage. To improve the truss, which is in poor condition, you usually spend seven or ten days. Therefore, before starting work necessarily representative of the company executive should carry out a conversation with the owner of the house, which needs to be aware of what work is necessary. Chimney Repair The new cover is laid over many years. Well, that as long as there was no need to go after him. Especially in order to perform the work, during which the roof may be dirty or damaged. Therefore, before laying the new coverage it is necessary to address the repair of the chimney. Ideally, the work will be started from the chimney sweep to check the patency of chimney smoke and ventilation systems. You can then proceed to repair work. Most is destroyed the upper part of the chimney, which was most exposed to the water and it contains chemicals and gases. Sometimes you only need a small repair, which usually takes days, sometimes you need re-brick chimney - and it takes nearly two days. Pre-mating-to-measure cover After you repair and protect rafter can join the pre-mating roof. Choice of solution depends on the covering material. Film pre-mating. It can be arranged directly on the rafters where the roof will be indoors rigid material - such as a roofing sheet, sheet metal, tiles, bituminous, cement or ceramic tiles. Belts foil are stacked on the roof forever, so that subtitles appear on top of the page. Then it will be guaranteed the right direction of movement of water vapor. They are arranged in 10-15-inch plant (usually the facility is marked on the film) and attached to the rafters. They are then nailed and perpendicular to these patches. While dimensions are not very important, that the patches are quite different. As a rule, are cross 2.4 x 4.8 cm. However, cross patches depends on several factors. Adjusted to the angle of the roof, climate zone, and above all the rafter spacing and the burden of coverage. For example, for rafter spacing up to 100 cm (often occurring in the past roofs) and the covering a relatively light material, such as bituminous roofing sheet or plate, patches may have a cross section of 5 x 4 cm. If you are going to be applied heavier material, such as roof tiles or cement, patches should be cross 6 x 4 cm. Information on the spacing of patches, depending on the covering material, and stretches the length of the slope angle is provided by the manufacturer's coverage. Just keep in mind that the distances between the patches must always be equal to and after docking patches on the calculated distance, you can begin attaching them to the selected coverage. Remember Pre-mating of the film is not recommended for roofs with a low angle of inclination of surface - 10-20 °. Then you better check, plus a complete formwork shingles.
