CertainTeed Roofing in La Mirada, CA | Select Roof Repair
We provide independent Roof Repair – La Mirada and CertainTeed roofing service across the 90637, 90638, and 90639 ZIP codes. Our crews know the Landmark, XT 25, Patriot, and Presidential Shake lines well, but what sets us apart here is understanding how La Mirada’s clay soils and mid-century tract construction actually stress those shingles over time. Call (855) 382-0485 for a free estimate. If your roof is leaking or shedding granules, we’ll figure out exactly what’s going on before recommending any work.
Why La Mirada Residents Choose Us for CertainTeed Service
We’re a roofing-only shop, which means every call we take is about shingles, flashing, underlayment, and decking. Not gutters, not windows, not “and also roofs.” That focus matters when you’re dealing with a specific product line like CertainTeed. Noel Carrasco, our owner, grew up in Midway City and spent 25 years fixing roofs across this part of LA County. He has pulled apart enough failing CertainTeed roofs in La Mirada to know the difference between a granule-loss problem that needs another five years of service and a decking situation that’s done. We stock common CertainTeed Landmark colors locally so repairs on La Mirada’s ranch-style and split-level homes don’t stall waiting for material. Need an inspection before committing to anything? CertainTeed sales & service starts with an honest diagnosis, not a pitch.

Common CertainTeed Roofing Problems We Solve in La Mirada
- Granule loss and accelerated aging on south and west slopes. Many original Landmark installations from the 1990s across La Mirada have baked under direct summer sun and periodic Santa Ana winds. The granules wear away, exposing the asphalt layer underneath. You might notice bare patches or find granules collecting in gutters. If caught early we can replace damaged sections; if the whole slope is failing, a targeted replacement makes more sense.
- Ridge shingle cracking from roofline shifting. Homes near the Puente Hills sit on expansive clay that moves with moisture and seismic activity along the Whittier Fault. That movement doesn’t stay in the foundation. It travels up through the framing, and the first place it shows on a roof is the ridge line. Cracked and lifted ridge shingles aren’t random wear, they’re structural movement, and re-nailing alone won’t fix the underlying cause.
- Flashing corrosion and sealant failure at valleys and penetrations. The original galvanized flashing on mid-century La Mirada tract homes has now survived fifty to seventy winters. Concentrated rainstorms in December through February find weak points where sealant has dried and metal has corroded. These leaks can be fixed with proper flashing replacement, but we’re honest when a patch would just postpone the next leak.
- Thermal cracking on low-slope patio and addition roofs. Many of the original tract homes in La Mirada had patios enclosed or rooms added during the 1970s and 80s. Those low-pitch sections often got minimal attic ventilation, and CertainTeed shingles installed over hot, under-ventilated spaces become brittle early. We regularly see thermal cracking in shingles on these additions even when the main roof still looks decent.
- Improper repairs from previous contractors. Because so many La Mirada roofs are hitting the end of their service life at the same time, we see a lot of patch jobs where someone nailed new shingles over old failed flashing or mismatched the shingle profile. Repair when it makes sense and replace when it doesn’t. That’s how we work, and fixing someone else’s shortcut usually costs more than doing it right the first time.
CertainTeed Service in La Mirada: What Local Conditions Mean for Your Equipment
Here’s something you won’t find on a generic CertainTeed page. La Mirada was built as a master-planned suburb in the 1950s and 60s, concentrated in original tract neighborhoods. Those homes share framing techniques, roof pitches, and, more importantly, the same underlying clay soil. The city straddles the Whittier Fault at the base of the Puente Hills. Expansive clay expands and contracts with moisture, and when it does, roof planes settle unevenly. We have seen this play out on Ashgrove Drive in the original tract near the hills in a 1962 ranch-style home. The homeowner called us about a persistent leak. We found ridge shingles cracked and lifted from roof-plane settlement, then discovered the original 1×6 skip sheathing had separated from the trusses due to soil movement. We re-secured the deck, installed new CertainTeed Landmark shingles in a matching color, and reinforced the ridge with high-wind nailing. The leak stopped, and the roof plane stopped shifting. That’s the kind of diagnosis that only comes from working in this specific part of La Mirada service area long enough to know what the soil does to a roof.
CertainTeed Models & Products We Service in La Mirada
We install and repair all of the CertainTeed lines still standing on roofs around the city. Landmark and Landmark Pro are the most common architectural shingles we see in La Mirada. XT 25 shows up on older homes, many from the late 1990s and early 2000s. We also service Patriot and Presidential Shake for homeowners who want a heavier, more dimensional profile. When a repair involves shingle replacement, we use CertainTeed OEM shingles to maintain warranty eligibility and color matching. For flashing and underlayment, we often source high-quality aftermarket products that meet or exceed OEM specs, because those components don’t affect the shingle warranty and the right aftermarket flashing often outlasts the original. For fast turnaround on La Mirada repairs, we keep common Landmark colors on hand locally. If your roof is past 20 years or the decking is showing widespread problems, we’ll tell you that full replacement beats repeated patching.

FAQs – CertainTeed Roofing in La Mirada
Look at the ridge line and the south-facing slopes first. If ridge shingles are cracked or lifting, especially on a 1950s or 60s tract home near the hills, that’s a sign of roof-plane movement, and full replacement with re-secured decking is usually the right call. If the issue is isolated to one slope, a few missing shingles, or a single flashing point, repair may serve you for years. We won’t charge for the inspection. Call (855) 382-0485 and we’ll tell you which path fits your roof and budget.
In La Mirada, the most common cause is soil movement. The clay-rich soils along the Whittier Fault expand and contract with moisture levels, moving the roof framing and cracking ridge shingles under the stress — a pattern we also address with our CertainTeed in South Whittier work. If that’s what’s happening on your roof, simply replacing the cracked shingles will fail again. The decking and framing need to be secured first.
Yes. We stock common Landmark colors locally and can order specific colors for less common CertainTeed profiles. Keep in mind that your existing shingles have weathered, so even the correct color will look slightly different for the first few months until the sun blends it in. We’ll show you the closest match before any work starts.
Yes, and those patio and addition roofs are exactly where we see thermal cracking and flashing failures on this housing stock, because the ventilation under them was often never right from the day they were built. Proper flashing replacement is the second most common service we provide in La Mirada after shingle replacement, and we offer the same expertise through our Buena Park CertainTeed service. Call (855) 382-0485 and we’ll inspect your patio roof as part of the free estimate.
Inland heat and Santa Ana winds in this part of southeast LA County shorten the lifespan of a typical CertainTeed architectural shingle to roughly 18 to 22 years. South- and west-facing slopes tend to age out around year 15 or 16. If your roof is approaching that age and you’re seeing granule loss or cracked shingles, replacing the failing slopes now often costs less than continuing to patch. Call (855) 382-0485 for a straightforward estimate.
