Roofer installation and assembly

Roof structure is often called “roofing pie” and not without reason – indeed, any rooftop includes several elements, which, sort of stratifying on each other, create strong safeguard for housing. 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 attention to the succession of coats 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 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 carried out with due regard to climate characteristics, building’s designation and architectural peculiarities, roof’s structure (flat or pitched). In addition, you should consider amount of loadings imposed by snow, winding and also other atmospheric phenomena.

Assembly of flat-deck and inclined roofs, other roofing activities require different approaches, equipment and appropriate understanding of installers. Consider an in depth examine different roofs’ specificities, while focusing on such important operational aspects as repairing, maintenance and mounting of rainwater systems.

Popular features of flat roofs installation

Flat roofs having a slope lower than 2.5 degrees are arranged by using fusion-bonded reel-fed materials or polymeric membranes. These stuffs are made particularly for terraced-roof option, customized considering 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 heat. Various mastics allow achieving waterproof membrane’s perfect impermeability.

Assembly of membranous rooftops is executed by attaching the material 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 applied for flat-deck roofs’ winterization. Installation technologies and insulation’s choices driven by roofing type and loads intensity into it.

Pitch roof installation notes

Pitched roofs which has a slope of above 8-12 degrees are engrossed in different roofing materials, among that your most common are clay tiles, metal tile, profiled sheeting, flexible bituminous shingle and cement-sand tiles. Generally choice 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, by which galvanized steel sheets are bonded in seams (single or double). Flexible bitumen tiles are laid on roof’s substructure, that’s preliminary required 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 means 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 presence of loft (or mansard), is made using fiberglass or mineral-based materials having density from 35 to 125 kg / cubic meter. Depending on whether attic or mansard is going to be arranged, heaters are attached over the slope or on ceiling slab respectively. Qualitative performing of works on roofing weatherization can substantially reduce electricity consumption for heating and improve reliability of the complete roof structure.

Roof repair

Roof repair, regardless of its type, is divided into current and capital. Current repairing includes eliminating small defects in coating (cracks, bumps, depressurization of joints), of course, if necessary, elements’ partial replacement. Major overhaul implies replacing roofing material, comprising dismantling of old covering, restoration of roof structure, setting up thermal insulation, setting up new coverage and painting (as appropriate).

Selection of material and type of the drainage elements is dictated by customer’s savings and aesthetic preferences. Typically, installing PVC gutters is cheaper, speculate of their properties to change under influence of temperature, plastic pipes and gutters can result in leakages. Modern rainwater systems’ manufacturers for this function develop special sealants delivered with PVC gutters, which may significantly prolong their lifespan.

Copper cunettes are believed is the most durable, but other metallic watercourses also have a fantastic performance and can serve for many 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. Works must be carried out with clear correspondence to requirements specified in regulatory documents, taking into account structure’s slope, dimensions, and lots of additional factors.
