Portland Composite Roofing

Composite roofing shingles are covered with a layer of weather-resistant mineral granules that act as UV protection for the underlying asphalt or fiberglass product. If the granule coating comes off failure of the roof is imminent as the harmful rays of the sun dry, crack and peel the remaining product on the roof.

This roof is in danger of that process. Notice the layer of granules in the rain gutter. This roof is actually a 30 year product, but at the time of this picture the product is only 7 years old. This product failure was caused by poor or improper attic ventilation. Professional installation by trained composite roofing professionals with the ability to foresee the unique challenges of your individual roof project is imperative for maximum roof life.


Legacy® is an architectural shingle line fortified with durable NEX™ polymer modified asphalt technology to promote superior granule adhesion and extreme weather protection, including Class 4 impact resistance. This product line includes the optional Scotchgard™ Protector from 3M for added protection against black streaks caused by algae.
