Composite Roofing is the lightweight alternative to traditional roofing products such as asphalt shingles, wood shakes, natural slate and cement or clay tile on the market. Composites or Synthetics can be made of either a base of rubber or plastic along with fillers or other additives. Composite roofing is made to look like the natural products in mainly three categories; Wood Shakes, Slate and Barrel Tile.
About the Composite Roofing Market:
Polymer Composites makes up less than 1% of the total residential roofing market with a value of approximately $159 million dollars. Composites are typically installed on higher end homes in distinctive neighborhoods for either new construction or re-roofs. The biggest advantage with composite roofing is that the roof does not need to be re-enforced. Many times the natural products require the trusses to be re-enforced to handle their weight, which can be 800-1,000 pounds per roofing square (100 square feet). Composite materials weigh in around 300-400 pounds per roofing square and do not need to be reinforced. The advantage of composite roofing is that it has the natural look without the weight challenges.
Composite Roofing Benefits:
- Lightweight – Most composites are 1/3 the weight of natural products – This makes roof loading & installation easier.
- Durability – More durable than the natural products. Less job site breakage.
- Natural Appearance – Most composites are designed to look just like the real thing.
- Most composites have the rich deep texture of natural slate, the authentic look of concrete or clay tiles and the natural splendor of cedar wood shakes.
- Colors – Composite shingles are available in a variety of colors and styles that replicate the look of the traditional products. To the naked eye many people will not be able to tell that it’s a composite.
- Performance – Many composites are tested to different building code standards such as ICC (International Code Council).
- Some composites have a special additive that makes them resistant to mold and algae growth.
- Composites can be installed with standard roofing tools (circular saw, drills, coil nail guns).
- Warranty – Composite Shingles generally have a 30-50 year warranty. Traditional shingles have a life span of 15-20 years.
- Fade resistant – Composites are made with UV stabilizers, meaning they will stand the test of time. Composites if made correctly will not fade to a different color, but they may have a slight change similar to that of siding.
An Eco-Friendly Roofing Alternative:
Composite shingles have a green message, not only are most of them made of recycled or eco-friendly material, they also are lighter weight which means better energy efficiency. Some items in composites would be land filled if they were not used to make the composite shingles. Most composite shingles are also recyclable at the end of their life.
