Every one of coating construction’s layers performs its designated role, whether that be moisture-proofing, noise insulation, or defense against heat loss. During roof’s installation you will need to pay particular focus on the sequence of coats in order to ensure effectiveness with their 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 advance of a real “pie”, which on the final stage is protected with cladding or thatching, and, if needed, is painted. Material selection to get the desired hermeticity and sturdiness is carried out with due regard to climate characteristics, building’s designation and architectural peculiarities, roof’s structure (flat or pitched). In addition, it is important to consider a higher level loadings imposed by snow, winding as well as other atmospheric phenomena.
Assembly of flat-deck and inclined roofs, other roofing activities require different approaches, equipment and appropriate knowledge of installers. Let’s take expose have a look at different roofs’ specificities, while keeping focused on such important operational aspects as repairing, maintenance and mounting of rainwater systems.
Options that come with flat roofs installation
Flat roofs with a slope less than 2.5 degrees are arranged by means of fusion-bonded reel-fed materials or polymeric membranes. These stuffs are designed especially for terraced-roof option, customized in light of its profile, that offers 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 between each other by hot-air welding method. Extruded heat retainers, mineral wool rigid insulants and expanded plastics are requested flat-deck roofs’ winterization. Installation technologies and insulation’s option is based on roofing type and loads intensity on it.
Pitch roof installation notes
Pitched roofs which has a slope of above 8-12 degrees are covered with different roofing materials, among that this most frequent are clay asphalt shingles, metal tile, profiled sheeting, flexible bituminous shingle and cement-sand tiles.

Corrugated sheets and metal shingles are installed by laying on lathing and fastening with special self-drilling screws. Folded covering assembly necessitates the utilization of specialized equipment, in which galvanized steel sheets are bonded in seams (double or single). Flexible bitumen tiles are laid on roof’s substructure, which is preliminary necessary to be carefully prepared – cleaned and dried. Mounting versatile bitumen plates is executed overlapping or on self-adhesive tile layer (sometimes – asphalt coating compound), or by way of nails. Types 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 in advance. Thermal insulation of inclined roofs, implying the existence of loft (or mansard), is produced using fiberglass or mineral-based materials having density from 35 to 125 kg / cubic meter. According to whether attic or mansard will be arranged, heaters are attached across the slope or on ceiling slab respectively. Qualitative carrying out of conditions roofing weatherization can substantially reduce electricity consumption for heating and improve longevity of your entire roof structure.
