CertainTeed Roofing in Los Angeles, CA | Brennan Roofing
CertainTeed roofing service in Los Angeles means working on roofs engineered for sun and fire exposure, not snow load. We’re Brennan Roofing, an independent CertainTeed service provider, and we install and repair CertainTeed asphalt shingle and tile systems across Los Angeles County. The difference here: we know how CertainTeed products behave under brutal summer UV, Santa Ana wind lift, and Chapter 7A hillside fire codes. For a written free estimate, call (361) 320-9467.
Why Los Angeles Residents Choose Us for CertainTeed Service
We’ve spent years working on CertainTeed roofs throughout Los Angeles as a trusted Los Angeles Roofing Company, from shake conversions in the Santa Monica Mountains to tile repairs in the San Gabriel Valley. Our technicians are background-checked and arrive in uniform. The price goes on paper before any work starts, and it doesn’t move at the door. That’s The Garrison Standard, and it’s the same on every job.
Travis Oakley grew up in the San Fernando Valley and trained at Los Angeles Trade-Technical College before spending the better part of two decades doing production and repair work across Los Angeles County. He still pulls his own inspections. When we tell you a repair is the right call instead of a full replacement, that’s a real assessment, not an upsell. A roof that’s squared away doesn’t need a sales pitch.
Common CertainTeed Roofing Problems We Solve in Los Angeles
- UV granule loss on Landmark shingles. Los Angeles summer sun bakes the granules off 15-to-20-year-old CertainTeed Landmark and XT 25 shingles faster than you’d see in a snow-belt city. South-facing slopes go first, exposing the asphalt and fiberglass mat underneath. Once granules are gone across a whole slope, the shingles are done.
- Thermal cracking on Presidential Shake TL and Grand Manor. Undersized attic venting on south-facing slopes cooks the shingles from both sides. The seal strips release, the shingles curl and slip, and we see it most on stucco tract homes from the 1950s through the 1980s where ridge venting was never added.
- Santa Ana wind lift at rakes and hips. CertainTeed field shingles lift and peel when the original install used a 4-nail pattern instead of the 6-nail high-wind pattern. We see this after every major Santa Ana event, particularly on hillside homes in the Hollywood Hills and above the Cahuenga Pass.
- Dry-rot at fascia, parapet, and eave edges. Winter rain intrudes at stucco transitions where underlayment has aged out. The underlayment stays wet, the stucco and fascia rot, and the shingles themselves look fine. Los Angeles’s short but violent rainy season exposes every weak flashing detail this way.
- Tile underlayment failure on Spanish Revival homes. Original clay tile on 1920s and 1930s Spanish Revivals often sits over underlayment that’s decades past its service life. The tile stays intact, but a ceiling stain after a winter storm tells you the underlayment is done.
CertainTeed Service in Los Angeles: What Local Conditions Mean for Your Equipment
Because the Hollywood Hills and Santa Monica Mountains sit inside Very High Fire Hazard Severity Zones, most hillside CertainTeed re-roofs here have to go back as a Class A fire-rated assembly with ignition-resistant edge and vent detailing. A shingle-only swap that would pass in most of the country won’t pass LAFD brush clearance review. That means even a straightforward CertainTeed shingle replacement on a hillside bungalow turns into a Chapter 7A detailing job at the ridge, eave, and vents. The shingle choice matters, but the assembly detail is where the permit lives or dies.
Los Angeles roofing also has to handle stucco over wood-frame construction on nearly every home built before the 1960s. Re-roofs here almost always involve stucco repair at the fascia and parapet, because the old stucco cracks and spalls when the old roofing is torn off. We schedule for that on the front end, not as a surprise change order. No-hassle upfront pricing means the stucco work is in the written estimate before we start.
CertainTeed Models & Products We Service in Los Angeles
We service and install the full CertainTeed asphalt shingle line: Landmark architectural shingles, Landmark TL, Presidential Shake TL, Grand Manor luxury laminates, and Symphony Slate. We also handle CedarLux and CedarImpression siding-to-roof tie-ins, and we use CertainTeed-branded or approved starter, ridge, and underlayment accessories to keep the system warrantable.
On the parts side, we match CertainTeed shingles by profile and color run number rather than swapping in a GAF or Owens Corning lookalike. That’s a real difference. The color run number is printed on the wrapper, and matching it means the repaired section won’t look like a patch. For faster turnaround across Los Angeles, we stock common Landmark colors locally and source specialty Presidential and Grand Manor profiles direct from our suppliers.

CertainTeed Service Pricing in Los Angeles
Los Angeles Roof Repair for CertainTeed systems typically runs $350 to $950 for flashing, valley, or sectioned shingle work. Tile underlayment replacement on a Spanish Revival roof usually lands between $3,500 and $8,500 depending on decking condition and access. A full CertainTeed Landmark re-roof on a standard 1,400 to 1,800 square foot post-war stucco home runs $9,000 to $16,000, and a Presidential Shake TL or Grand Manor re-roof runs $16,000 to $28,000. Hillside homes in the Very High Fire Hazard Severity Zone add Class A detailing, staging, and access costs that can push the total higher.

FAQs – CertainTeed Roofing in Los Angeles
Yes. We match CertainTeed Landmark shingles by profile and color run number, not by eyeballing the color. The run number is on the original wrapper, and matching it keeps the repaired section from looking like a patch. If the original run is discontinued, we’ll tell you before we start and show you the closest current match. Call (361) 320-9467 for a free inspection and exact quote.
In most Los Angeles Spanish Revivals we see, the clay tile is still solid and the underlayment is shot. The underlayment had a 20-to-30-year design life, and most original tile roofs are now 80 to 100 years old. We lift and set aside the tile, replace the underlayment with CertainTeed WinterGuard or RoofRunner, and relay the same tile. You don’t buy new tile, and you get a watertight system. Call (361) 320-9467 for an exact quote – estimates are free.
CertainTeed Landmark and Presidential shingles are Class A fire-rated products, but the zone above Hollywood has additional Chapter 7A requirements for the assembly, not just the shingle. The ridge, eave, and vent details must be ignition-resistant, and LAFD brush clearance review will check those details. We build those assemblies to pass the first time. Call (361) 320-9467 for a free hillside compliance assessment.
Most likely, the original install used a 4-nail pattern instead of the 6-nail high-wind pattern CertainTeed specifies for high-wind zones. Under sustained Santa Ana gusts, the seal strips release at the exposed edges first. We re-secure lifted shingles to the 6-nail pattern and add sealant at the rake edges. If the lift is widespread, we’ll give you an honest assessment on repair versus re-roof. Call (361) 320-9467 for a free inspection.
We install CertainTeed roofing systems using CertainTeed-branded or approved accessories, so your manufacturer warranty is honored according to CertainTeed’s terms and your registration. We’re an independent service provider, not manufacturer-affiliated, and we won’t compromise the system with off-brand parts that void the warranty. Every Brennan Roofing job also comes with our 365-Day Done Right Promise: in writing, for one full year, and we come back for free if it fails. Call (361) 320-9467 to schedule your free estimate.
