Asphalt is a sticky, black, and semi solid-liquid form of petroleum. It can be found naturally in deposits. Asphalt is used in roof shingles. The topcoat of organic asphalt shingles contains solid granules while the base mat contains cellulose, waste paper, and wood. Fiberglass asphalt shingles consist of a base layer containing fiberglass bonded with urea formaldehyde resin. Asphalt shingles are widely used and reputed all over the world.

Asphalt shingles have a high quality which can withstand winds, storms, fires and discolorations due to external factors.

• Asphalt shingles have high wind resistance due to the bond strength of seal adhesive, high quality fasteners and proper nailed techniques.

They have excellent heat insulation and fire resistance properties that help prevent damages to your roof caused by accidental fires, lightning strikes, or nearby forest fires. Class A, Class B, and Class C have high resistance, medium resistance and light resistance, respectively. Choose the class by considering environmental conditions of the area, as well as security needs and the associated cost.

When the roof becomes wet, copper and zinc are released to protect your roof covering. For further maintenance, you can follow an accepted treatment plan for your roof to prevent algae stains. So, it is possible to maintain a clean and clear roof without stains and discolorations.
