CertainTeed Construction in Placentia, CA | Square One Builders
We provide independent CertainTeed construction service across Placentia, focusing on roof replacement, roof repair, and the roof tie-ins that come with ADU conversions on older lots. What makes our CertainTeed work different here is simple: almost every job in Placentia is a tear-off or re-roof over an existing structure, not new construction. That changes how we spec underlayments, flashing, and shingle lines. Call (877) 688-9930 for a free estimate.
Why Placentia Residents Choose Us for CertainTeed Service
We’ve spent years installing and tearing out CertainTeed roofing, siding, and trim systems on Placentia’s pre-war and mid-century homes. We know how Landmark architectural shingles behave on shallow-slope, re-decked roofs here, and how Flintlastic underlayment performs when Santa Ana winds push embers and debris across the 92870 core. We’re an independent CertainTeed service provider, not authorized or warranty-endorsed by the manufacturer. We spec and install the brand because it works, and because we can match it to Placentia’s specific housing stock.
Brent Calloway, our owner and general contractor, grew up in the Midway City pocket off Bolsa Avenue and has spent nearly three decades working on Orange County homes. He learned framing, concrete, and finish work through Golden West College’s Construction Technology program, then earned his reputation on whole-home remodels and additions where the structural work holds up as clean as the finish. When we take on a CertainTeed roof in Placentia, the same standard applies.

Common CertainTeed Construction Problems We Solve in Placentia
- Wind-lift and tab loss on Landmark shingles at ridges and rake edges. Placentia sits in the Santa Ana wind corridor, and we regularly see architectural shingles peeled back where re-roofs over older decking left nail placement uneven. We re-secure, replace damaged tabs, and detail the edges so the next wind event doesn’t repeat the damage.
- Granule loss and premature aging over under-ventilated mid-century attics. The low-pitch 1950s roofs in Placentia’s older core often have original gable vents that don’t move enough air. Summer heat bakes the shingles from below, and CertainTeed granule surfaces erode years early. The fix is usually ventilation first, then shingle replacement where the mat is exposed.
- Flashing and underlayment failures around detached-garage-to-house tie-ins. When a Placentia homeowner converts a detached garage to an ADU, the new wall intersections meet 60-year-old roofing. We see water intrusion right at those transitions because the original flashing was never designed for a structural connection. We detail those tie-ins and refit with CertainTeed accessories before drywall goes up.
- Winter rain intrusion at valleys and drip edges. Older Placentia homes with deferred gutter maintenance let water back up under Flintlastic underlayment and shingle courses. We trace the leak to its actual source, which is often a clogged valley or a drip edge that’s rusted through, not the shingle field itself.
- Shallow footing problems that surface during garage-to-ADU roofing. We’ve torn off roofs on detached Placentia garages and found the slab has settled or cracked. Before we tie a new CertainTeed roof into a garage that’s becoming living space, the footing has to be checked. It’s the difference between a roof that lasts and one that flexes with every seasonal soil shift.
CertainTeed Service in Placentia: What Local Conditions Mean for Your Equipment
Placentia is fully built out. There is essentially no new-subdivision roofing work here. Every CertainTeed job is a tear-off or re-roof over existing structure on narrow old-core lots, and the detached single-car garages that make prime ADU conversion targets often sit on shallow footings. Before we can tie a new roof into those garages, we have to check the slab and the setback. The city’s history as a citrus-packing town means crews work around a mix of pre-war and mid-century homes with later infill pressed in alongside. Matching existing conditions matters here more than in Yorba Linda or other neighboring new-build cities. So does knowing which CertainTeed assembly will hold up on a low-pitch 1950s roof with original framing and tight side yards. We plan every Placentia roof job around those constraints, not around a catalog photo.
CertainTeed Models & Products We Service in Placentia
We install and repair CertainTeed Landmark architectural shingles, including Landmark Pro and Landmark Solaris. For luxury profiles, we work with NorthGate and Presidential Shake. On the siding side, we handle Monogram and CedarBoards insulated vinyl. Underneath, we use Flintlastic self-adhered underlayment and RoofRunner where the deck calls for it. We stock genuine CertainTeed starter strips, ridge vent, and specified underlayments locally for fast Placentia turnaround. Mixing aftermarket accessories with CertainTeed shingles voids the wind and fire ratings, and we won’t do it. When an older Placentia deck is too far gone for a targeted repair, we’ll tell you that a full tear-off is the smarter spend.

FAQs – CertainTeed Construction in Placentia
Landmark architectural shingles can work on low-slope roofs down to 2:12 pitch, but only with the right underlayment and deck preparation. Many 1950s Placentia homes have original skip-sheathing or uneven decking that needs re-decking first. We’ll inspect the slope and deck condition and tell you straight whether Landmark is appropriate or if you need a low-slope system instead. Call (877) 688-9930 and we’ll check it in person.
Yes, it can. When a detached garage becomes living space, the roof tie-in to the main house gets stressed in ways the original assembly wasn’t designed for. We’ve seen flashing failures at those transitions within a year or two when they weren’t re-detailed during the conversion. We handle both the CertainTeed roof and the ADU build in Placentia, so the tie-in gets done right the first time. Call (877) 688-9930 to scope it.
Landmark architectural shingles carry a 110 mph wind warranty when installed with the full CertainTeed system, including starter strips and proper nail placement. But that rating assumes the deck underneath is solid and the nailing pattern is correct. On older Placentia re-roofs where the deck is uneven, wind-lift at ridges and rake edges is the most common failure we fix. We re-deck where needed and detail the edges so the shingles hold. Call (877) 688-9930 for a wind-damage inspection.
It depends on the deck condition and how much of the shingle field is failing. A targeted repair on a 20-year-old Placentia roof can buy you three to five years if the underlayment is intact and the deck is solid. If the granules are gone across large areas or the Flintlastic is tearing, a full tear-off is the smarter spend. We’ll give you an honest read either way. Call (877) 688-9930 and we’ll look at it together.
Both. Square One Builders is a general contractor, not a roofing-only shop. We can re-roof your Placentia home with CertainTeed and build the detached garage ADU conversion under one contract, and we bring the same approach to CertainTeed in Anaheim. That means one team checks the footings, sets the setbacks, details the roof tie-in, and finishes the interior. No separate specialists to coordinate. Call (877) 688-9930 for a free estimate.
