Modified Bitumen Roofing

Modified bitumen offers improved flexibility and durability compared to traditional BUR systems. It is often heat-welded or self-adhered for installation.

• Pros: Durable, flexible, relatively easy to install.
• Cons: Can be punctured by sharp objects, may require periodic maintenance.

EPDM Roofing (Rubber Roofing)

EPDM is a popular choice for its flexibility and resistance to weathering. It’s often used on low-slope roofs.

• Pros: Flexible, weather-resistant, relatively low cost.
• Cons: Can be punctured by sharp objects, limited color options.

TPO Roofing

TPO is a highly reflective material, making it an energy-efficient choice. It’s also known for its resistance to chemicals and UV radiation.

• Pros: Energy-efficient, durable, resistant to chemicals and UV radiation.
• Cons: Can be more expensive than some other options, potential for seam failure if not properly installed.

Metal Roofing

Metal roofing offers exceptional longevity and aesthetic appeal. It’s available in a wide range of colors and styles.

• Pros: Long-lasting, durable, aesthetically pleasing.
• Cons: Can be expensive, noisy during rain, can dent under impact.

Green Roofing

Green roofs provide numerous environmental benefits, including reduced stormwater runoff and improved air quality. They also offer added insulation.

• Pros: Environmentally friendly, provides insulation, reduces stormwater runoff.
