Roofer installation and assembly
Roof structure can often be called “roofing pie” instead of without reason – indeed, any rooftop consists of several elements, which, type of stratifying on every other, create strong safeguard for housing. Every one of coating construction’s layers performs its own designated role, whether that be moisture-proofing, noise insulation, or defense against heat loss. During roof’s installation it is very important pay particular focus on the sequence of coats to guarantee 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 this type of “pie”, which with the final stage is included with cladding or thatching, and, if needed, is painted. Material selection to get the desired hermeticity and durability is completed with due regard to climate characteristics, building’s designation and architectural peculiarities, roof’s structure (flat or pitched). Furthermore, it is important to consider level 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 understanding of installers. Let’s take a detailed examine different roofs’ specificities, and focus on such important operational aspects as repairing, maintenance and mounting of rainwater systems.
Top features of flat roofs installation
Flat roofs using a slope below 2.5 degrees are arranged by way of fusion-bonded reel-fed materials or polymeric membranes. These stuffs are designed particularly 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 hot air. 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 option is determined by roofing type and loads intensity into it.
Pitch roof installation notes
Pitched roofs using a slope of above 8-12 degrees are engrossed in different roofing materials, among which the most popular are clay asphalt shingles, metal tile, profiled sheeting, flexible bituminous shingle and cement-sand tiles. Generally choice of suitable option id driven by customer’s selections 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 involves the using 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 important 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 by means of 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 existence of loft (or mansard), is made using fiberglass or mineral-based materials having density from 35 to 125 kg / cubic meter. Determined by whether attic or mansard is going to be arranged, heaters are attached across the slope or on ceiling slab respectively. Qualitative carrying out of works on roofing weatherization can substantially reduce electricity consumption for heating and improve robustness of the complete roof structure.
Roof repair
Although installing done by professionals ensures housetop’s trustability and its primary function – protection against atmospheric precipitation, nevertheless ultimately an absolute necessity of repair arises. Roof repair, irrespective 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 top, installation of thermal insulation, installation of new coverage and painting (if necessary).
Timely conduction of current repairs allows to keep up the roof in excellent condition with minimal resources and efforts. Permanent maintenance done by professionals is essential to detect and fix defects.
Roofing maintenance
In order to extend roofing’s service life and eliminate the requirement of major repairs, attendance is carried out, implying thorough inspection and removal of existing defects. Various kinds of covering require individual approach and professionalism. Examination carried out at least two times 12 months for timely detection of potential problems. Roofing service could also include roofing cleaning spillway chutes and pipes, sealing elements of roofing system, cleaning debris, ice and snow through the roof, painting factors that have lost their original appearance and several other pursuits.
Drainage systems arrangement
Organization of gutters is necessary action in building any rooftop. For pitched roofs exterior drainage product is used, comprising pipes and gutters fabricated of metal or PVC. Properly organized water disposal shields facade and basement from premature destruction upon exposure to moisture and, in addition, allows giving the house more finished attractive look.
Selection of material and form of the drainage elements is dictated by customer’s savings and aesthetic preferences. Typically, installing PVC gutters is less costly, but because of the properties to change under influence of temperature, plastic pipes and gutters can bring about leakages. Modern rainwater systems’ manufacturers for this function develop special sealants delivered with PVC gutters, that may significantly prolong their lifespan.
Copper cunettes are considered 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 essential for optimal calculation of load, imposed on drainage system. Works ought to be carried out with clear correspondence to requirements per regulatory documents, taking into consideration structure’s slope, dimensions, and a lot of variables.
