AfterCertainTeed Roofing in San Francisco, CA | Brennan Roofing
CertainTeed roofing service in San Francisco typically costs $350 to $1,400 for repairs and $12,000 to $28,000 for a full replacement, depending on whether you have a flat Flintlastic membrane or shingle roof. We’re Brennan Roofing, a San Francisco Roofing Company and independent CertainTeed service provider working across the city, and the one thing that makes our work different here is simple: we know parapet flashing is usually the real problem, not the membrane. If your roof is leaking or nearing the end of its life, call (361) 320-9467 for a free estimate.
Why San Francisco Residents Choose Us for CertainTeed Service
We’ve torn off, repaired, and reinstalled every major CertainTeed line that shows up on San Francisco’s Victorian and Edwardian row houses: Landmark architectural shingles, XT 25 three-tabs, Flintlastic modified bitumen, and Preserve metal roofing. We know how they fail here, in this city, under fog that never fully burns off and rain that comes in sideways from October through March. Travis Oakley, our owner, built Brennan Roofing on a straightforward idea: show up on time, use materials worth putting your name on, and never hand a homeowner a bill that surprises them. That discipline flows through every CertainTeed repair and replacement we do in San Francisco. We use OEM accessories and membranes when they match the existing system, and quality aftermarket flashings and fasteners when an exact match isn’t available and the substitution won’t compromise the roof.
Every job starts with a written price in hand. Before any work begins, you have the number on paper, and it does not move at the door. Our technicians are background-checked and arrive in uniform. You know exactly who’s on your roof. And if something isn’t right, the 365-Day Done Right Promise covers it in writing for one full year, with a free return visit at no charge. We also answer our phones with a live person around the clock. No voicemail, no automated system. For more on how we handle CertainTeed work, see our CertainTeed sales & service page.
Common CertainTeed Roofing Problems We Solve in San Francisco
- Landmark shingle curl and granule loss. On steep cottage roofs in Noe Valley and Bernal Heights, Landmark architectural shingles lose granules and curl at the edges after years of fog moisture that never fully dries. Once the edges curl, wind-driven rain from October storms gets underneath and finds the decking.
- XT 25 three-tab cracking at the tabs. Older additions and detached garages often have XT 25 three-tab shingles. The tabs crack when the underlying decking flexes, which is common in pre-1950 wood-frame structures with skipped sheathing. You see this all over the Mission and the Richmond.
- Flintlastic ponding water and parapet flashing failure. Flat Flintlastic modified bitumen roofs in the Sunset and Richmond pond water at low spots. The real leak is almost always at the parapet flashing, where cracked sealant and a clogged drain let water sit against the termination bar until it finds a way through.
- Preserve metal fastener back-out and rust at cut edges. Preserve metal roofing panels on rooftop decks and light wells develop fastener back-out and surface rust at cut edges because of year-round dampness and poor ventilation. Leaks track along the panel seams and show up inside far from the source.
- Multiple layers of old roofing on narrow lots. Most San Francisco roofing work means tearing off multiple old layers on a narrow lot with party walls. When old tar and shingle layers are stacked three deep, a localized patch won’t hold, and a full tear-off is the only durable option. We’ll tell you that straight.
CertainTeed Service in San Francisco: What Local Conditions Mean for Your Equipment
San Francisco roofing is dominated by flat, low-slope roofs hidden behind ornate street-facing parapets, and those parapets, not the roof membrane itself, are the most common failure point and code-inspection trigger. That changes how CertainTeed work plays out here. In most cities, a flat roof patch means addressing the field of the membrane. In San Francisco, it means coordinating with historic facade rules that don’t apply in Sacramento or Fresno. Our CertainTeed work here is as much about preserving ornate street-facing cornices and light-well details as it is about waterproofing the roof. After the first big November storm, our crew got a call from a homeowner on 24th Street in the Mission whose CertainTeed Flintlastic flat roof was leaking into a back bedroom. We found the parapet flashing had cracked and pulled away from the ornate cornice, with ponding water sitting on the membrane because a roof drain was clogged with eucalyptus leaves. We patched the Flintlastic, replaced the flashing with a compatible termination bar and sealant, cleared the drain, and the leak stopped, without touching the historic street-facing parapet finish. That’s the kind of detail that matters here.
CertainTeed Models & Products We Service in San Francisco
We service every major CertainTeed line you’ll find on San Francisco roofs. Landmark architectural shingles are the most common on steeper cottage roofs. XT 25 three-tabs show up on older garages and additions. Flintlastic modified bitumen membranes cover the thousands of flat and low-slope roofs across the Sunset, Richmond, and Mission. Preserve metal roofing appears on rooftop decks, light wells, and occasional modern additions. We stock common CertainTeed OEM accessories locally for fast turnaround, and when an exact OEM match isn’t available, we use quality aftermarket flashings and fasteners that won’t compromise the system. For repairs, we tell CertainTeed owners honestly when a localized fix will hold, especially at parapet flashings and roof drains, and when multiple layers of old material mean a full tear-off is the only option that will last.

FAQs – CertainTeed Roofing in San Francisco
Yes, if the curling and granule loss is limited to a few shingles and the underlayment is still intact. A localized repair runs $350 to $900. If the decking is soft or multiple shingles have lifted across a whole slope, a full replacement is the honest answer. Call (361) 320-9467 for an exact quote, estimates are free.
Leaks at the parapet happen because that’s where the membrane terminates and the sealant degrades first. Add a clogged drain and ponding water, and the first big November storm finds the crack. We repair the flashing, clear the drain, and patch the Flintlastic, usually for $650 to $1,400. Call (361) 320-9467 and we’ll take a look.
Most repairs don’t need a permit, but if the work touches an ornate street-facing parapet or cornice, the city’s historic facade rules may kick in. We’ll tell you what applies before work starts. Full replacements do require permits, and we handle that paperwork. Call (361) 320-9467 and we’ll walk you through it.
The first dry week after that storm is the busiest of the year, because roofers can’t tear off in the rain. We schedule replacements in the order calls come in and we hold to the written schedule. A full tear-off and replacement usually takes three to six working days, depending on layers and parapet work. Call (361) 320-9467 to get on the schedule before the next system rolls in.
It can be, but in San Francisco, Preserve metal needs attention to fastener back-out and rust at cut edges because of year-round dampness. Proper panel sealing and ventilation at the deck level make the difference between a leak-free roof and one that tracks water along the seams. We’ll give you a straight answer on whether Preserve fits your building. Call (361) 320-9467 for a free estimate.
