GAF Roofing in Century City, CA | Marquis Roof Repair
We provide independent GAF roofing service across Century City, specializing in the low-slope commercial membranes and high-rise terrace detailing that dominate this district’s towers. The work here is almost never shingle work, it’s EverGuard TPO seams, Ruberoid modified bitumen parapets, and Liberty self-adhered base plies on buildings where a single failed flashing can send water fourteen floors down. If you manage or own property in Century City and need GAF membrane diagnosis, repair, or replacement, call (866) 705-2978.
Marquis Roof Repair has spent years working the dense blocks between Avenue of the Stars and Century Park East, where GAF commercial systems live on nearly every rooftop. We’re an independent GAF service provider, never authorized or manufacturer-affiliated, which means our recommendations come from what your roof actually needs, not what a brand program tells us to push. From first inspection to final seam, we handle the full roof lifecycle under one name. Call (866) 705-2978 for a free estimate.
Why Century City Residents Choose Us for GAF Service
Century City property managers and HOA boards don’t have time for a roofer who’s learning on the job. They need someone who knows exactly what a GAF EverGuard TPO seam looks like when ponding water has started to compromise it, or what UV brittling on a Ruberoid cap sheet means for the next winter storm. That’s the work we do here, and it’s why our GAF service in Century City — and GAF service in West Hollywood nearby — gets calls from building engineers and condo association presidents alike.
Ron Thibodeau, our owner, cut his teeth in the San Fernando Valley and studied building construction technology at Los Angeles Valley College before spending more than two decades on commercial and residential roofs. He built Marquis Roof Repair around a methodical diagnostic approach, we investigate before we recommend, and that’s especially true when a Century City penthouse starts leaking through a terrace-door threshold. He’ll tell you a roof done right the first time is the only version worth doing.

Common GAF Roofing Problems We Solve in Century City
- Ponding water at GAF EverGuard TPO seams. Century City’s flat membranes are prone to low spots where undersized drains or scuppers let water sit. That standing water softens the seam adhesive on TPO and eventually opens fishmouths that leak during the first real December rain.
- UV-brittled Ruberoid SBS cap sheets at parapets. Our near-coastal sun beats on Century City parapet flashings year-round. The heat cycling and UV exposure make the modified bitumen brittle, and wind-driven water tracks behind the wall termination into penthouses and mechanical rooms.
- Clogged roof drains and scuppers backing up Liberty base plies. High-rise roofs collect debris, and Century City’s rooftop equipment screens and amenity decks add to the problem. When drains clog, water backs up at mechanical curb penetrations, saturating the deck and showing up as ceiling stains in units below.
- Foot traffic damage on TPO walkway areas. Rooftop amenity decks on Century City condo towers get real use. Unprotected GAF TPO walkway areas grind embedded dirt into the membrane, accelerating seam wear and creating pinhole leaks near terrace door thresholds.
- Terrace-door threshold flashing failures. On a Century Park East condo tower, we traced a December leak from a luxury unit fourteen floors down to a failed GAF Ruberoid flashing at a terrace-door threshold. UV-brittled cap sheet had pulled away from the parapet, and water had been traveling through the penthouse for weeks before it surfaced.
GAF Service in Century City: What Local Conditions Mean for Your Equipment
Here’s the thing about Century City that changes how GAF roofing work actually plays out here. This district was built on the old Twentieth Century Fox backlot, and today it’s governed by strict design-review and view-corridor standards on Avenue of the Stars towers. That means a replacement GAF membrane color, or a parapet height modification, often has to clear building design review before we can set a single roll. A roofer from North Hollywood or Burbank, or one used to GAF repair in Culver City, never faces that hurdle. We do. If your building’s GAF membrane needs replacement and you’re on a design-review-protected tower, plan for that approval step, and we’ll help you navigate it. It’s part of why GAF service in Century City requires a contractor who’s worked through those approvals before, not just someone who can weld a seam.
GAF Models & Products We Service in Century City
Our crew works on the GAF commercial lines that dominate Century City rooftops: EverGuard TPO membrane, EverGuard PVC, Liberty SBS self-adhering systems, and Ruberoid modified bitumen. For repairs, we specify GAF-manufactured membrane, flashing, and accessory components wherever the assembly is still serviceable, and we pair them with quality aftermarket fasteners and sealants when OEM lead times would stall a winter leak repair. We stock common GAF TPO and SBS seam materials and edge-metal components locally, which keeps turnaround fast for Century City buildings that can’t wait through a supply chain delay.

FAQs – GAF Roofing in Century City
Drains are the low points on flat Century City roofs, so water ponds there longest. That standing water sits directly on the TPO seam adhesive, softening it over time and causing fishmouths that open during winter rain events. Clear the drains and scuppers before the rainy season, and have the seams inspected. Call (866) 705-2978 for a free drain and seam assessment.
Yes, when the field membrane and substrate are sound, a Ruberoid parapet flashing can be replaced with new GAF Ruberoid membrane and edge metal without touching the rest of the roof. We honestly patch when the seam and base ply are still serviceable, and we’ll tell you when they aren’t. Call (866) 705-2978 to schedule an inspection.
Yes. Because Century City was built on the old Fox backlot and is governed by strict design-review and view-corridor standards, replacement GAF membrane colors and parapet heights on Avenue of the Stars towers often must clear building design review before installation. Your property manager or HOA can confirm the specific requirement for your building, and we’ll coordinate with the review board.
For heavy foot traffic on a Century City rooftop deck, we typically recommend GAF EverGuard TPO with a walkway membrane or pavers over the membrane surface. Unprotected TPO grinds embedded dirt into the membrane and accelerates seam wear near terrace door thresholds. Call (866) 705-2978 for a free amenity deck assessment and material recommendation.
The marine-influenced, near-coastal climate means Liberty self-adhered base plies stay coated in moisture for longer stretches during winter. If drains are clogged or scuppers blocked, that moisture sits against the adhesion layer and can compromise the bond at mechanical curb penetrations. Clear the drains, and call (866) 705-2978 for an inspection before the wet season starts.
