CertainTeed Roofing in Downey, CA | Birchbark Roofing Long Beach
Our Roofing Company in Downey provides independent CertainTeed roofing service across the city, from shingle repair to full replacements on homes built mostly between 1950 and 1965. What makes our CertainTeed work different here is that we plan every job around two Downey realities other roofers tend to skip: the city’s pre-1980 asbestos testing requirement for tear-offs, and the wind patterns that hit those Santa Ana seasons hard. If you need CertainTeed shingles repaired, matched, or replaced, call us at (562) 512-7366 for a free estimate with a written price before anyone climbs a ladder.
Why Downey Residents Choose Us for CertainTeed Service
CertainTeed shingles show up on a lot of Downey roofs, particularly Landmark and XT 25 lines on the 1950s and 60s tract homes south of Firestone. Our crews know these profiles well enough to spot a failing nail pattern before the wind does. Erik Lindgren, our owner, started roofing through the construction trades program at Los Angeles Trade-Technical College, and he has spent the better part of two decades walking roofs across the area, including older homes where the original shake still hides under a newer CertainTeed layer. That background matters when the job involves a tear-off on a mid-century Downey house. We’re an independent CertainTeed service provider, not a manufacturer-authorized dealer, which means we recommend what the roof actually needs rather than what a warranty program pushes.

Common CertainTeed Roofing Problems We Solve in Downey
- Granule loss and curling along south-facing eaves. Downey summers deliver long stretches of direct sun, and Landmark shingles on southern exposures shed granules faster here than on shaded slopes. We see the earliest cupping right along the eave line, where reflected heat from the gutter edge stacks on top of ambient heat.
- Wind-lifted tabs after Santa Ana events. Older XT 25 installations with nails placed too high in the shingle slot are the first to lift when a Santa Ana comes through. The shingle holds until the seal strip weakens, then a whole tab folds back. We re-nail or replace those sections before the next wind season, not after.
- Corner cracking on Grand Manor shingles. Low-slope sections in north Downey get more thermal expansion than steeper pitches. Grand Manor shingles have a thicker, stiffer profile, and on roofs below 3:12 we find cracks starting at the corners where the shingle can’t flex enough to absorb the movement.
- Hidden asbestos-containing layers under older CertainTeed re-roofs. Plenty of Downey homes had CertainTeed shingles applied directly over original 1950s built-up roofing or wood shake with asbestos felt. Tearing off a roof like that without testing first creates a disposal problem and a health one. We coordinate the testing and abatement before we strip anything.
- Flashing failures at side walls and chimneys on mid-century homes. The original flashing on many Downey homes is the same age as the house. When a newer CertainTeed roof gets installed but the old flashing isn’t replaced, leaks show up at the wall line within a few seasons. We inspect the flashing every time, even when the job quote is just for shingles.
CertainTeed Service in Downey: What Local Conditions Mean for Your Equipment
Downey’s municipal code requires asbestos testing and special handling for any tear-off from buildings constructed before 1980, and since most of the housing stock dates to the 1950s, nearly every full replacement we bid touches this rule. That’s the information most generic roofing pages miss. A house in Long Beach or Lakewood might need a testing step occasionally. In Downey, on a full CertainTeed re-roof over an original wood shake layer, it’s nearly a given. Our tech just finished stripping a 1954 ranch on Firestone Boulevard where the homeowner had Landmark shingles installed over the original wood shake. The hidden shake layer had asbestos felt beneath it, so we brought in a licensed abatement crew before installing new decking and Grand Manor shingles with wind-resistant nailing for the next Santa Ana season. The code step adds a day or two to the project but it’s not optional, and any roofer who skips it leaves you holding a disposal violation and a liability you never asked for. For homes in the older section of Downey service area, we quote the testing and abatement coordination up front, in writing, so the number you approve is the number on the final invoice.
CertainTeed Models & Products We Service in Downey
We work on the full range of CertainTeed roofing lines common in Downey: Landmark Series, XT 25 Series, Grand Manor Series, and Presidential Shake Series. For active lines, we use genuine CertainTeed shingles and accessories when matching an existing roof so the color and profile blend cleanly and any remaining warranty terms stay intact. For older, discontinued lines, we source quality aftermarket equivalents that match in profile and color. Our supplier network across the Long Beach and Downey area keeps common Landmark and Presidential Shake stock available for fast turnaround, so a small repair doesn’t turn into a two-week order-and-wait. We recommend repair where the decking is sound and the shingle line can still be matched. We recommend replacement when granule loss exceeds roughly 40% across the field or the underlayment has begun to fail.

AfterCertainTeed Service Pricing in Downey
What drives cost on a CertainTeed repair or replacement in Downey varies with three things: the pitch and accessibility of the roof, whether a tear-off triggers the city’s asbestos testing and abatement step, and whether you’re matching an active shingle line or sourcing a discontinued equivalent. Small shingle repairs and flashing fixes typically run lower than full replacements, and the pre-1980 testing requirement adds a known, fixed line item when it applies. The estimate itself is free. You’ll see exactly what we’ll do, what materials go on, and the total number in writing before you approve anything. Erik’s rule is simple: a written price before anyone climbs a ladder, that’s where we start. Call (562) 512-7366 to schedule your free estimate.

FAQs – CertainTeed Roofing in Downey
Santa Ana winds find the weakest fastening pattern on your roof and exploit it, usually lifting tabs on older XT 25 installations where nails were driven too high in the shingle slot. The fix is a re-nail or sectional replacement with wind-resistant nailing before the season starts. Call (562) 512-7366 and we’ll inspect your fastening pattern for free.
Yes, if the building was constructed before 1980 and the tear-off will reach the original layers. Downey’s code requires testing and certified handling for asbestos-containing materials. We coordinate the lab test and licensed abatement so you don’t have to manage the process yourself. The coordination is included in every full replacement quote we write for mid-century Downey homes.
Grand Manor and Presidential Shake hold their granules longer than lighter architectural lines under Downey’s hot, dry summers, mainly because their thicker construction resists the thermal movement that loosens the granule bond. But the right product also depends on your roof’s pitch and whether the decking is original. We’ll tell you what your specific roof needs after walking it, not before.
Usually yes. We source aftermarket shingles that match the profile and color of discontinued CertainTeed lines, and we install them in the least visible section when a perfect dye-lot match isn’t possible. You’ll see the match against your existing roof before we order, and the written estimate will say exactly what we’re using. Call (562) 512-7366 for a free match assessment.
Low-slope roofs absorb more heat per square foot and expand more through the day than steeper pitches. Grand Manor shingles, with their thicker, stiffer profile, can develop corner cracks when the thermal expansion outpaces the shingle’s ability to flex. It’s a known failure mode on low-slope sections across north Downey, and our Roof Repair in Downey usually means a fix with proper fastening and underlayment, not a full replacement. We’ll tell you which one after a roof walk.
