Renton Roofing: Article About Composite Roof Shingles
Millions of homeowners order the installation of traditional asphalt shingles for their homes not realizing the beneficial differences of composite shingles. Lightweight, fire safe and fade resistant, composite roofing materials are made from poly-based products and other materials that are commonly used on roofs. Although they are newer to the roofing industry, Renton roofing experts have the knowledge and experience to install them properly.
One aspect of composite shingles that wins over homeowners is that they can be manufactured to look like other types of roofing material. Several manufacturers have developed varieties that mimic wood, laminate and slate. They are also available in nearly any size, shape and color. Some composite shingles look so realistic that they are approved for historic preservation projects. Additionally, high quality manufacturers boast high impact resistance for their composites.
Traditional asphalt shingles have been popular for many years and come in fiberglass or organic varieties. The fiberglass type contains a mat made from fiberglass and an asphalt layer added to the top. The organic type has a paper backing or mat and an asphalt layer on top. Composite shingles are made from several materials such as wood, shake, slate, laminate, tar paper and asphalt. It's the combination of materials that makes these shingles more durable and stronger.
Traditional organic asphalt shingles are considered less damaging to the environment than fiberglass, but fiberglass is more popular because it is more durable.

Composite shingles are more environmentally friendly and durable than both of the traditional varieties because they are made from recycled materials. Manufacturers typically use post-industrial plastics, used roofing materials and hemp fibers to reduce waste.
There are also differences in the features that traditional and composite shingles provide. Asphalt shingles have a layer of mineral granules that contains leachable copper to help with the resistance of algae growth. The granule coat also helps with reflecting the sun's UV light to reduce weathering that eventually causes the shingles to crack and fade in color. Composites have inhibitors that prevent the formation of moss and algae. They have a coating that reflects UV light, but composites do not crack, warp, blister, split or peel. Additionally, the color of composite shingles does not fade more than one shade over their full life expectancy.
The longevity of traditional asphalt shingles is between 15 and 20 years. This depends on the weather in the location of the home and how well the homeowner maintains the roof. Manufacturers generally offer five to 20 year warranties on traditional shingles. Composite roofs last anywhere from 30 to 50 years, and manufacturers generally offer warranties for that amount of time.
