Most modern homes have aluminum cladding installed over bare wood fascia boards (where the eavestroughs are secured to), and on the under-hangs (soffits), under the roof structure.
Many older homes are retrofitted with such materials to eliminate the need for painting and to preserve bare wood surfaces beneath. The installation of such materials can freshen and modernize the appearance of homes, in addition to reducing the maintenance requirements.
Relative to the cost of preparing and painting such surfaces, aluminum installation and capping represent a far more economical, and often safer, choice for home owners.
Avenue Road Roofing will first correct any deficient wood work to insure structural integrity prior to cladding these areas.
Aluminum cladding materials come in a variety of colours. Cladding work is custom bent on site to fit the structure. Soffit materials are pre-formed by the manufacturer, and cut to width on site by the installer.
Installation of such materials requires metal profiles designed to secure such materials in place. J- trim is used to secure soffit where it adjoins wall surfaces. J-trim is also used around perimeters of windows and doors with drip cap flashings being used to shed water from the tops of windows or sills.
Special attention must be given to areas such as recessed pot lights, light fixtures and wall protrusions, such as on porch under-hangs.
Siding is used to clad large wall surfaces, gable ends, and dormer walls. This highly durable material is available in a variety of materials such as aluminum, vinyl, fibrous cement and wood. Various profiles exist in each of these categories, with vinyl and aluminum representing the most popular and most cost effective options.
ARR’s trained installation technicians first prepare wall surfaces which are to receive such siding materials. The first step involves insuring a true wall surface. If underlying structural lumber or sheeting requires replacement, the carpentry will be completed. Charges for wood repair are at a fixed linear or square foot price as detailed in our estimate forms.
Level wall insulation is a product which may be used over existing surfaces such as insul-brick to help account for variations in a walls existing surface. When conducting siding work, there is an opportunity to increase the thermal efficiency of the home by adding rigid styrene insulation. Differing R values may be achieved depending on the thickness of the insulation used. When installing thermal wall insulation on the exterior of a building, it is required to install a vapour retarder layer such as Tyvek builders wrap, and tape the overlapping joints. This helps to resist exterior moisture and migrant cold air from entering the structure. Insulation may then be added over top.
Various profiles of siding are available in horizontal and vertical configurations. Decorative profiles for gable ends and dormer applications, are designed to compliment traditional siding profiles and create architectural interest. Such designs include scallops, dentil moldings, and the appearance of cedar shakes. Trim components such as manufactured exterior corner posts and trim flashings are used to provide the finished appearance of the installation.
It is key to secure siding correctly to avoid buckling, oil canning, or popping of the materials. Fasteners must not be so tight as to prevent the natural expansion and contraction of the structure. Proper staggering of siding laps and level placement are hallmarks of a superior installation.
Vinyl is the most popular choice for siding as it is more thermally efficient, resists impact dents, and fading, as a result of the colour being integrated throughout the extrusion, as opposed to painted on such as with aluminum or steel.
Aluminum siding is often specified to be used in circumstances where houses are in close proximity to one another to being compliant with fire code requirements. Certain customers prefer the look and feel of such material, particularly if being mated to existing house areas or neighbourhood character.
When securing siding to an existing wall, the surface determines what method of attachment is required. On concrete or masonry surfaced, wood strapping is installed on two foot centres. In the case of wood, the siding may be directly secured if no insulation is present.
Cleaning Up After The Job Is Done
All debris is removed and legally disposed of off site. An impeccable clean up of the grounds is performed, along with a magnetic sweep to vet stray fasteners. All required areas are caulked with professional grade sealant.
When completing such work, steps to insure the safest possible work conditions must be factored into the cost of the investment. Scaffolding, installing roof jacks & planks, blanketing hydro wires which are near or attached to the building can be requirements to protect workers and limit liability for the client.
The estimator will advise their client of such hazards, and factor in the proper requirements to produce the job safely and efficiently.
