EPDM rubber roofing
The ethylene propylene diene monomer (EPDM) creates a single layer rubberized roof that is long lasting and UV resistant. EPDM roofing systems do not require a mineral coating, which makes them much lighter than tar and gravel roofs. It should be noted that a rigid insulation is recommended for this type of roof.
Pros:
- Energy Efficient
- Can be used with a wide variety of roof shapes
- Cleaner application than many low slope options
- Performs well in high wind and hail
- Good long-term performance for a low slope roof
Cons:
- Not intended for high rain or snow areas
PVC membrane roofing systems
PVC membrane is a roof membrane composed of only one layer of material, polyvinyl chloride. PVC roofs are specially designed to withstand ponding water- PVC membrane is welded together with hot air (no open flame) to eliminate all seams so moisture can not pass through. PVC roofing systems also reflect nearly 90% of the heat of the sun, thus lowering energy costs substantially, especially in high-heat areas such as the southwestern United States.
Pros:
- Fire safe material
- Energy Efficient
- Good weather resistance
- Good long-term performance for a low slope roof
Cons:
- Not intended for high rain or snow areas
