Commercial TPO Roofing
OAKLAND, CAInstallation of a GAF TPO membrane roofing system on a commercial building.
Commercial Division
Flat and low-slope roofing solutions for commercial buildings, retail locations, office parks, and multi-family buildings in Northern California.

Commercial Solutions
Commercial properties require specific fire ratings, chemical resistance, and installation techniques designed for low-slope drainage.
Thermoplastic Polyolefin membranes offer heat-welded seams and high solar reflectivity for lower cooling costs.
Liquid-applied restoration systems that seal minor leaks and restore reflectivity without a full tear-off.
We plan, schedule, and isolate work areas to prevent traffic interference or noise disruption for active tenants.
Strict OSHA safety standards, perimeter safety warning lines, and heat-welding safety protocols.
We specialize in flat-roof assemblies using manufacturer-tested materials.
A properly installed and maintained GAF TPO membrane system can last 20 to 30 years depending on the thickness of the membrane and regional weathering conditions.
Yes. If the underlying insulation layers are dry and the system is structurally sound, a liquid silicone coating can extend the roof life by 10 to 15 years at a fraction of the cost of a full replacement.
Why The Badge Matters
GAF invites a select group of roofing contractors in North America to become GAF Master Elite® Contractors. It isn't awarded for volume — it reflects a track record GAF is willing to stand behind with its own warranty.
That backing means qualifying roofs installed by ABC Builders Group can carry enhanced, manufacturer-issued warranty coverage — not just a contractor's workmanship guarantee.
