Asphalt Shingles
Asphalt shingles are one of the most common roofing materials used in Ontario homes, and indeed around the country. They offer many years of performance at a lower initial cost than other roofing materials and are a solid choice for any homeowner on a budget. There are two main categories of asphalt shingles: organic and fiberglass. Over the last several years, organic shingles have been replaced by fiberglass shingles, a preferable shingle used by Home Vision. Fiberglass shingles are lighter, less expensive, more heat resistant and more durable than the organic ones. Organic shingles are more resistant to high winds and tearing.
Components
– Granular surface layer provide color and UV protection, reflect heat and keep the roof temperature cool.
– Asphalt coating is the waterproof agent. The asphalt thickness defines the quality and the performance.
– The base it’s the element that holds the other layers together. At organic shingles it’s made of felt paper, whereas the fiberglass shingles are reinforced with a fiberglass mat.
