5. Polyvinyl Chloride (PVC) Roofing
PVC roofing is a single-ply membrane known for its strength, fire resistance, and energy efficiency.
Pros:
- Highly durable with a lifespan of 25+ years.
- Resistant to chemicals, grease, and fire.
- Strong seams prevent leaks and water damage.
Cons:
- Higher installation costs.
- It can become brittle in extremely cold weather.

7. Modified Bitumen Roofing
Modified bitumen roofing consists of asphalt-based materials reinforced with fiberglass or polyester for added durability.
Pros:
- Flexible and resistant to cracking.
- Easy to install and maintain.
- Good waterproofing capabilities.
Cons:
- Less energy-efficient compared to white or reflective roofs.
- Prone to punctures and tears over time.
- Shorter lifespan (10-20 years) compared to other options.
