SBS Roofing FAQs

Common questions about SBS modified bitumen roofing.

What does SBS stand for?

SBS stands for Styrene-Butadiene-Styrene, a rubber polymer that's added to asphalt to create a more flexible, durable roofing membrane. This modifier gives the membrane excellent cold-weather performance.

Is torch-applied roofing safe?

Yes, when performed by trained professionals with proper fire safety protocols. Our crews follow strict hot-work procedures including fire watches and safety equipment. For sensitive buildings, we offer cold-applied alternatives.

How does SBS compare to TPO or EPDM?

SBS offers superior puncture resistance and is easier to repair than single-ply membranes. It's often preferred for roofs with heavy foot traffic or equipment. Single-ply options may be more cost-effective for simpler applications.

Can SBS be installed in cold weather?

Yes—SBS is one of the best cold-weather roofing options. Torch-applied systems can be installed in temperatures that would prevent adhesive-based products from bonding properly.
