All of coating construction’s layers performs its very own designated role, whether that be moisture-proofing, noise insulation, or defense against heat loss. During roof’s installation you will need to pay particular care about the succession of coats in order to ensure effectiveness of the functions. Basic elements are:
– damp-proof membrane and vapor sealing pellicle;
– warmth-keeping lagging;
– protection against wind;
– roof-boarding material;
– ventilation arrangement;
– other components.
Roof installation implies creation of a real “pie”, which at the final stage is included with cladding or thatching, and, as appropriate, is painted. Material selection to search for the desired hermeticity and durability is carried out with due regard to climate characteristics, building’s designation and architectural peculiarities, roof’s structure (flat or pitched). Moreover, you will need to consider level of loadings imposed by snow, winding and other atmospheric phenomena.
Assembly of flat-deck and inclined roofs, other roofing activities require different approaches, equipment and appropriate expertise in installers. Let’s take expose take a look at different roofs’ specificities, and focus on such important operational aspects as repairing, maintenance and mounting of rainwater systems.
Popular features of flat roofs installation
Flat roofs with a slope lower than 2.5 degrees are arranged through fusion-bonded reel-fed materials or polymeric membranes. These stuffs were created specifically for terraced-roof option, customized in light of its profile, that provides them maximum protection against weathering, ultraviolet exposure, etc. Assembling rolled materials is accomplished by welding sheets of roll composition roofing using hot air. Various mastics allow achieving waterproof membrane’s perfect impermeability.
Assembly of membranous rooftops is executed by attaching the information to roofing’s screed; membrane sheets are fastened in between each other by hot-air welding method. Extruded heat retainers, mineral wool rigid insulants and expanded plastics are sent applications for flat-deck roofs’ winterization. Installation technologies and insulation’s option is based on roofing type and loads intensity on it.
Pitch roof installation notes

Generally collection of suitable option id driven by customer’s priorities and size budget allotted for housetop arrangement.
Corrugated sheets and metal shingles are installed by laying on lathing and fastening with special self-drilling screws. Folded covering assembly requires the usage of specialized equipment, through which galvanized steel sheets are bonded in seams (double or single). Flexible bitumen tiles are laid on roof’s substructure, that is preliminary necessary to be carefully prepared – cleaned and dried. Mounting versatile bitumen plates is executed overlapping or on self-adhesive tile layer (in certain cases – asphalt coating compound), or by using nails. Type of slate are laid on prepared lathwork; shingles are attached using stating nails with rubber gasket and anticorrosion cap. Holes for nails in sheets of slate are drilled beforehand. Thermal insulation of inclined roofs, alluding to presence of loft (or mansard), is made using fiberglass or mineral-based materials having density from 35 to 125 kg / cubic meter. Based on whether attic or mansard will likely be arranged, heaters are attached across the slope or on ceiling slab respectively. Qualitative performing of creates roofing weatherization can substantially reduce electricity consumption for heating and improve reliability of the whole roof top.
Despite the fact that installing done by professionals ensures housetop’s trustability and its primary function – protection against atmospheric precipitation, nevertheless eventually essential of repair arises. Roof repair, no matter its type, is split into current and capital. Current repairing includes eliminating small defects in coating (cracks, bumps, depressurization of joints), and if necessary, elements’ partial replacement. Major overhaul implies replacing roofing material, comprising dismantling of old covering, restoration of roof top, installing thermal insulation, installing new coverage and painting (as appropriate).

Copper cunettes are thought is the most durable, but other metallic watercourses have an outstanding performance which enable it to serve for decades. “General Builder” also offers solutions for flat roofs, where internal runoff systems, including spillway funnels, pipes and connectors, are organized. Professionals’ participation is important for optimal calculation of load, imposed on drainage system. Works needs to be through with clear correspondence to requirements specified in regulatory documents, considering structure’s slope, dimensions, and many other factors.
