Why La Mirada Residents Choose Us for CertainTeed Service
CertainTeed shingles cover a lot of roofs in La Mirada, and we know them the way you know your own street. Rick Dunnigan, our owner, grew up in Buena Park CertainTeed service territory and cut his teeth patching ranch-style homes along Orangethorpe Avenue before spending two-plus decades on roofs across Orange County. That background means we don’t read CertainTeed specs from a manual; we’ve handled the specific failure patterns these shingles develop after decades of inland heat and Santa Ana wind. We’re an independent CertainTeed service provider, not manufacturer-authorized, and we’d rather tell you what your roof actually needs than push a scope you don’t need. That’s the whole point: repair when possible, replace when necessary.

Common CertainTeed Roofing Problems We Solve in La Mirada
- Granule loss on Landmark shingles after inland heat exposure. La Mirada summers bake roofs, and CertainTeed Landmark 30-year shingles that have been up for 20+ years often shed granules to the point where the fiberglass mat dries out and cracks. We see this constantly on the original 3-tab and early architectural roofs throughout the 90638 tract grid.
- Santa Ana wind lift on east-facing slopes. Santa Ana winds hit east slopes hard, and when the seal-down strip on CertainTeed shingles is already aged and dusty, whole tabs lift or crease. This is the most common wind-related call we get in La Mirada after a strong Santa Ana event.
- XT 25 and XT 30 three-tab shingle keyway failure. Older La Mirada homes that were never re-roofed often still carry XT 25 or XT 30 three-tab shingles. When tabs break at the keyway and expose fasteners, water gets in. We’ll patch these when the surrounding shingles still have life; we’ll tell you to replace when they don’t.
- Failed underlayment masquerading as shingle failure. On CertainTeed roofs in La Mirada, water often reaches the deck long before a visible leak shows indoors because the underlayment beneath the Landmark courses has heat-aged and split. If the shingles look okay but you have ceiling stains, that’s often the culprit.
- Original skip sheathing under wood shake complicating a CertainTeed re-roof. Many La Mirada homes built in the 1950s-60s still carry spaced skip sheathing under their original wood shake. You can’t lay CertainTeed shingles over that, so a re-roof becomes a decking conversion, not a simple overlay.
CertainTeed Service in La Mirada: What Local Conditions Mean for Your Roof
Here’s the thing most roofers won’t tell you until they’re already tearing your roof off: in La Mirada, a CertainTeed re-roof often isn’t a re-roof at all. It’s a decking rebuild. The 1950s-60s tract homes that fill this city were largely built with spaced skip sheathing under wood shake, and that construction was never designed to take a modern architectural shingle like CertainTeed Landmark directly. When you pull the old shake, you find gaps between boards, not a solid nailing surface. Putting Landmark over that would void the install before it’s done. So the scope changes: we pull the spaced boards, sheath solid, add new underlayment, then lay the CertainTeed courses. That change of scope is also what sends the job into La Mirada City Hall for permit review, because you’re altering the roof structure, not just re-covering it. On a mid-1960s single-story in the 90638 tract grid, our crew found exactly this: original skip sheathing beneath worn wood shake the homeowner wanted swapped for CertainTeed Landmark. We pulled the spaced boards, re-decked solid, then installed new underlayment and Landmark courses. The homeowner mentioned the east slope had been lifting after a prior wind event, so we secured it with fresh starter and hip-and-ridge while we were up there.
CertainTeed Models & Products We Service in La Mirada
We work on the full range of CertainTeed roof systems you’ll find across La Mirada: Landmark architectural shingles, XT 25 and XT 30 three-tab shingles, Presidential Shake luxury shingles, and Flintlastic SA self-adhered modified bitumen on the city’s many low-slope roofs. We install genuine CertainTeed shingles, starter, hip-and-ridge, and underlayment so the system and any remaining material warranty stay intact. We don’t swap in mismatched bargain bundles to save a few dollars. Our work with seven manufacturers, including CertainTeed sales & service, means we match material to the job, not to what’s left in the warehouse.

AfterCertainTeed Service Pricing in La Mirada
CertainTeed service costs in La Mirada depend on what we find once we’re on the roof. A simple shingle replacement runs lower; a decking conversion on an original skip-sheath roof runs higher because of the structural work and permit requirements. Here’s what you’ll see in an estimate:
- Shingle repair or replacement: priced per square of certainTeed material plus labor and access
- Decking replacement: added per sheet when sheathing or skip sheathing is compromised
- Underlayment replacement: included when the deck is opened, quoted separately when the shingles are being matched
- Permit fees for decking conversions: passed through at cost, no markup
Your free estimate includes a written, line-item quote and our honest read on whether you need a patch or a full replacement. Call (866) 282-5070 to schedule one, and we’ll tell you what the roof actually needs.

FAQs – CertainTeed Roofing in La Mirada
Yes, we can match your existing CertainTeed Landmark shingles when the surrounding courses are still sound. We stock common Landmark colors locally for fast La Mirada turnaround, and for less common colors we order direct so the match is correct rather than approximate. If the decking underneath is failing, though, a patch won’t hold, and we’ll tell you that plainly. Call (866) 282-5070 for an exact quote; estimates are free.
No, you cannot install CertainTeed shingles directly over spaced skip sheathing. The gaps between boards don’t give the shingles a solid nailing surface, and any install over that would fail. What we do in La Mirada is convert the deck: pull the spaced boards, sheath solid, add new underlayment, then lay the CertainTeed courses. It’s a structural change that goes through La Mirada City Hall permit review. Call (866) 282-5070 for a free decking inspection.
The lifted shingles on your east slope after a Santa Ana event are very often a seal-down issue, not a CertainTeed product defect. The seal-down strip ages and gets dusty over years of inland heat, and once it loses adhesion, wind gets under the tabs and lifts or creases them. We repair this by cleaning the seal-down area and re-securing the tabs with genuine CertainTeed material. When the shingles are beyond resealing, patch replacement makes more sense. Call (866) 282-5070 for an assessment.
We install CertainTeed shingles, starter, hip-and-ridge, and underlayment to the manufacturer’s installation specifications, which is what allows the material warranty to apply. We’re an independent service provider, not manufacturer-authorized, so we don’t sell the extended CertainTeed warranty programs. What we do provide is our own workmanship warranty on the install. Ask us about specifics when you call (866) 282-5070.
Yes, we service GAF, Owens Corning, IKO, Atlas, Tamko, and Boral roofs as well as CertainTeed.
