Polycarbonate roofing panels are made from lightweight, affordable and highly durable thermoplastic material that can withstand almost any climate and weather. The poly roofing that we use most often is a “clear tinted” product that works similar to the way a tinted car window does. It’s 100% waterproof and blocks 99% of the sun’s harmful UV rays while still allowing some natural light to come through. This durable and practical roofing material is perfect for pergolas, carports, pavilions and other outdoor covered structures. Poly roofing panels can be installed for an additional $5 per square foot.
