During roof’s installation you will need to pay particular attention to the sequence of coats in order to ensure effectiveness of these 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 coming of this kind of “pie”, which at the final stage is covered with cladding or thatching, and, as appropriate, is painted. Material selection to get the desired hermeticity and sturdiness is completed with due regard to climate characteristics, building’s designation and architectural peculiarities, roof’s structure (flat or pitched).

Assembly of flat-deck and inclined roofs, other roofing activities require different approaches, equipment and appropriate expertise in installers. Let’s take a detailed 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 using a slope lower than 2.5 degrees are arranged by way of fusion-bonded reel-fed materials or polymeric membranes. These stuffs are made specifically for terraced-roof option, customized considering its profile, which gives them maximum protection against weathering, ultraviolet exposure, etc. Assembling rolled materials is accomplished by welding sheets of roll composition roofing using heat. 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 requested flat-deck roofs’ winterization.

Flexible bitumen tiles are laid on roof’s substructure, that is preliminary required to be carefully prepared – cleaned and dried. Mounting versatile bitumen plates is executed overlapping or on self-adhesive tile layer (in some instances – asphalt coating compound), or through nails. Varieties 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 upfront. Thermal insulation of inclined roofs, implying the presence of loft (or mansard), is produced using fiberglass or mineral-based materials having density from 35 to 125 kg / cubic meter. Based on whether attic or mansard will probably be arranged, heaters are attached over 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 entire roof structure.

Copper cunettes are considered is the most durable, but other metallic watercourses also provide a fantastic performance which enable it to serve for several years. “General Builder” also provides solutions for flat roofs, where internal runoff systems, including spillway funnels, pipes and connectors, are organized. Professionals’ participation is necessary for optimal calculation of load, imposed on drainage system.
