Composite Roofing

Frequently Asked Questions


What is Composite Roofing?

Composite roofing shingles are made of recycled plastics and other sustainable materials. The plastic materials used to produce composite materials may include fiberglass, recycled paper products, and asphalt. Essentially composite roofing materials are plastic shingles. These composite shingles are fire resistant and do not have problems with moisture. Some manufacturers produce a shingle that is resistant to algae and mold growth. Most composite roofing shingles do not crack, peel, split or warp and come in a variety of colors, which makes them a desirable option for homeowners looking to upgrade their roof.

How does composite roofing compare to asphalt shingles?

Asphalt shingles are the most popular roofing material in the United States. They are affordable and widely available. Composite roofing materials provide a longer warranty and more realistic look than asphalt shingles. Composite materials can be manufactured to mimic the look of most roofing materials (slate, tile, cedar shake). Asphalt shingles are also more heavy than composite materials, so composites are easier for your roofing contractor to install and transport on the job site.

How does composite roofing compare to genuine slate or cedar roofing?

With advancements in technology, composite materials are now able to provide the same natural beauty and aesthetic appeal of real slate or real cedar without the weight issues or organic degradation. Real slate provides a home with stunning beauty, however it is very heavy. Depending on the thickness of a real slate roof, you can expect slate to weigh 5.5 – 7.3 pounds per square foot. By comparison, a composite CeDUR roof weighs just 1.7 pounds per foot. If you are thinking about putting real slate on your roof it is best to consult with a structural engineer prior to installation to ensure that your building can withstand the weight of a new slate roof.

The problem with real cedar is organic degradation over time. While chemical treatments and preservatives are commonly used on real wood roofs, a wood roof is still susceptible to algae and mold growth, rotting, cupping, curling, warping, nail popping, splitting, cracking, water absorption, insect and debris build up, UV damage, splintering and graying / fading. In addition, real wood is extremely flammable. If you live in a high fire danger area, an area with a wood shake ban, or you live in a mountainous community, it is recommended that you do not put on a real cedar wood roof. Instead you should look at a composite alternative like CeDUR. CeDUR will not degrade over time, our composite synthetic manufacturing process provides lasting beauty, and our proprietary fire retardant technology will self-extinguish flame spread in the event of a fire and keep your home safe in the event of a fire. CeDUR Roofing Shakes are perfect for any region or climate in the world. Other plastic composite shingles may become brittle or break in freezing climates. CeDUR can withstand the coldest and hottest climates. All of our products feature a 50 Year Limited Material Warranty.

How long does composite roofing last?

Composite roofing materials are recognized for their long-term durability. While other roofing shingles last on average 15-20 years, most composite roofing materials are warrantied anywhere from 30-50 years.
