Asphalt shingles are perhaps the most commonly used material for roof replacement due to their color selection, styles, warranties, and relatively low cost, providing excellent protection in a wide range of environments. A professional Virginia contractor will install Asphalt shingles in layers. Shingles installed in layers are then traditionally trimmed with three tabs with each subsequent row overlapping the previous layer by one third. This provides a small gutter effect on each layer of the shingles that helps water and melting snow run off the roof without seeping underneath. Each shingle usually has a thin bead of tar on the underside, which will adhere to the upper layer further sealing them from leaks. An advantage of asphalt shingles is that most Virginia licensed contractors usually offer a guarantee for 20 years and in some instances, 30 years.
Wood Shake Shingles
Wood shake shingles are also popular with many VA contractors and over time tend to weather to a gray color, or silver depending on the type of wood used. Shake shingles, made of cedar, weather well and are cut thicker than other types of wood shingles and are typically split from logs rather than evenly cut. An important installation aspect of wood shingles is their need to breath and they are not mounted over a solid substrate, like asphalt shingles. Pressure treated lattice or newly-developed plastic materials are often used as an underlayment that provides for a flat surface while still allowing air to circulate under and around the wood shingles.
Regardless of the material used, flashing will need to be installed around chimneys, vents, pipes, and any other type of protrusions through the roof to prevent leaks. Sunshine Contracting uses only the best flashing metals and exterior caulk so you can rest assured your roof will not leak.
