MODIFIED BITUMEN

COMMERCIAL MODIFIED BITUMEN ROOFING IN NEWNAN, GA

OUR BELL MODIFIED BITUMEN SYSTEMS

At Bell Roofing, we install the ModBit 10 system, a commercial modified bitumen roof for Newnan businesses that includes a 10-year warranty covering materials and labor. This system is an excellent choice for commercial roofs with a 1/12 pitch or steeper, ensuring efficient water runoff. It's built using two key components from the GAF Liberty System: a securely fastened base sheet and a durable asphaltic top layer. GAF, the manufacturer of the modified bitumen membrane, meticulously inspects every ModBit 10 roof. We designed this system to provide businesses with a cost-effective and dependable flat roof solution that prevents leaks—without the high price tag of single-ply membranes.

Businesses can also opt for the Bell ModBit 15 system for their commercial roofing needs. This system comes with a comprehensive 15-year warranty on materials and labor. It is ideal for roofs with a slope of 1/12 or more, facilitating effective water drainage. The ModBit 15 system incorporates effective insulation and a robust two-layer design from the GAF Liberty System. This includes a tightly attached base sheet and a resilient asphaltic top layer. GAF, the manufacturer of the modified bitumen used in this system, conducts a thorough inspection of each installation. With the Bell ModBit 15, we provide businesses in Newnan with a modified asphalt roofing system that is durable and budget-friendly and provides superior leak protection without the premium cost of single-ply membranes.

For maximum protection and longevity, we offer the Bell ModBit 20 system, which includes a 20-year materials and labor warranty. This system is engineered for flat and low-slope roofs with a pitch of 1/12 or higher to ensure effective water drainage. It features high-quality insulation and a three-layer design based on the GAF Liberty System. This system incorporates two staggered base sheets for enhanced strength and a long-lasting asphaltic top layer. To ensure top-notch quality, every ModBit 20 roof undergoes a rigorous inspection by GAF, the company that manufactures the modified bitumen membrane. With this system, Bell Roofing delivers a premium, leak-proof commercial modified bitumen roof for Newnan businesses that desire a high-performing, long-lasting roof that offers cost savings compared to single-ply membrane options.
