Roofer installation and assembly
Roof top is frequently called “roofing pie” rather than without reason – indeed, any rooftop contains several elements, which, form of stratifying on every other, create strong safeguard for housing. 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 it is important to pay particular care about the sequence 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 type of “pie”, which at the final stage is covered with cladding or thatching, and, if required, is painted. Material selection to discover the desired hermeticity and durability is conducted 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 amount of loadings imposed by snow, winding along with other atmospheric phenomena.
Assembly of flat-deck and inclined roofs, other roofing activities require different approaches, equipment and appropriate familiarity with installers. Let’s take expose 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 using a slope less than 2.5 degrees are arranged by means of fusion-bonded reel-fed materials or polymeric membranes. These stuffs are made particularly for terraced-roof option, customized in light of its profile, that 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 pad 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 applied for flat-deck roofs’ winterization. Installation technologies and insulation’s options are dependant on roofing type and loads intensity on it.
Pitch roof installation notes
Pitched roofs using a slope of above 8-12 degrees are covered with different roofing materials, among that your most popular are clay roofing shingles, metal tile, profiled sheeting, flexible bituminous shingle and cement-sand tiles. In many instances selection of suitable option id driven by customer’s personal preferences and size budget allotted for housetop arrangement.
Corrugated sheets and metal shingles are set up by laying on lathing and fastening with special self-drilling screws. Folded covering assembly necessitates the usage of specialized equipment, in which galvanized steel sheets are bonded in seams (single or double). 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 (in some cases – asphalt coating compound), or by using nails. Species 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 produced using fiberglass or mineral-based materials having density from 35 to 125 kg / cubic meter. Determined by whether attic or mansard will be arranged, heaters are attached down the slope or on ceiling slab respectively. Qualitative doing of preps roofing weatherization can substantially reduce electricity consumption for heating and improve toughness for your entire roof top.
Roof repair
Despite the fact that installing performed by professionals ensures housetop’s trustability and its primary function – protection against atmospheric precipitation, nevertheless sooner or later essential of repair arises. Roof repair, irrespective of 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, installation of thermal insulation, setting up new coverage and painting (if needed).

Range of material and type of the drainage elements is dictated by customer’s financial resources and aesthetic preferences. In many instances, installing PVC gutters is cheaper, speculate of their properties to improve under influence of temperature, plastic pipes and gutters can result in leakages. Modern rainwater systems’ manufacturers for this reason 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 provide an excellent performance and will serve for years. “General Builder” also offers 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 ought to be carried out with clear correspondence to requirements specified in regulatory documents, taking into consideration structure’s slope, dimensions, and a lot of additional factors.
