Flat roofs with a slope significantly less than 2.5 degrees are arranged by indicates of fusion-bonded reel-fed components or polymeric membranes. These stuffs are created especially for terraced-roof option, customized in light of its profile, that offers them maximum protection against weathering, ultraviolet exposure, and so forth. Assembling rolled supplies is achieved by welding sheets of roll composition roofing using hot air. Numerous mastics enable reaching waterproof membrane's excellent impermeability.



Assembly of membranous rooftops is executed by attaching the fabric to roofing's screed; membrane sheets are fastened in between one another by hot-air welding method. Extruded heat retainers, mineral wool rigid insulants and expanded plastics are applied for flat-deck roofs' winterization. Installation technologies and insulation's option is determined by roofing form and loads intensity on it.



Pitch roof installation notes

Mounting versatile bitumen plates is executed overlapping or on self-adhesive tile layer (in particular cases - asphalt coating compound), or by implies of nails. Species of slate are laid on ready lathwork; shingles are attached using stating nails with rubber gasket and anticorrosion cap. Holes for nails in sheets of slate are drilled ahead of time. Thermal insulation of inclined roofs, implying the presence of loft (or mansard), is made using fiberglass or mineral-based supplies possessing density from 35 to 125 kg / cubic meter. Based on irrespective of whether attic or mansard are going to be arranged, heaters are attached along the slope or on ceiling slab respectively. Qualitative carrying out of performs on roofing weatherization can substantially minimize electricity consumption for heating and boost reliability of the complete roof structure.

Roof repair, regardless of its type, is divided into present and capital. Current repairing incorporates eliminating little defects in coating (cracks, bumps, depressurization of joints), and if vital, elements' partial replacement. Main overhaul implies replacing roofing material, comprising dismantling of old covering, restoration of roof structure, installation of thermal insulation, installation of new coverage and painting (if needed).

Adequately organized water disposal shields facade and basement from premature destruction upon exposure to moisture and, moreover, enables giving the house additional finished eye-catching look.



Selection of material and shape with the drainage elements is dictated by customer's financial resources and personal aesthetic preferences. In most cases, installing PVC gutters is much less expensive, but due to their properties to adjust under influence of temperature, plastic pipes and gutters can result in leakages. Modern rainwater systems' suppliers for this objective create special sealants delivered with PVC gutters, which can drastically prolong their lifespan.



Copper cunettes are regarded to be the most sturdy, but other metallic watercourses also have a superb performance and can serve for decades. "General Builder" also offers solutions for flat roofs, where internal runoff systems, such as spillway funnels, pipes and connectors, are organized. Professionals' participation is important for optimal calculation of load, imposed on drainage system. Works needs to be carried out with clear correspondence to needs specified in regulatory documents, taking into account structure's slope, dimensions, and many other variables.
