Common Flat Roofing Materials
Flat roofs have different needs than pitched roofs, especially when it comes to waterproofing. Here are some of the most common materials:
1. EPDM (Rubber Roofing)
A durable synthetic rubber membrane, EPDM is widely used due to its affordability, flexibility, and resistance to weather.
2. TPO (Thermoplastic Polyolefin)
TPO is a single-ply membrane known for energy efficiency and strong resistance to UV rays and chemicals.
3. PVC (Polyvinyl Chloride)
PVC roofing is highly durable and often used in commercial applications. It resists fire, moisture, and chemicals.
4. Modified Bitumen
This asphalt-based material comes in rolls and is applied with heat or adhesive. It’s known for being tough and weather-resistant.
5. Built-Up Roof (BUR)
A traditional method using layers of tar and gravel, BUR is extremely durable but heavy and labor-intensive to install.
