CertainTeed Roofing in Redlands, CA | Oakmont Roof Repair
We provide independent CertainTeed roofing service across Redlands, from downtown Craftsman bungalows to the 92374 tract subdivisions east of the 10. The thing that sets our CertainTeed work apart here is the split housing stock: half of Redlands wears original clay tile while the other half carries baked asphalt shingles now in their second or third cycle. We know exactly how CertainTeed’s product lines age under Inland Empire heat, and we’ll tell you whether a repair or a replacement is the honest call. Call (866) 942-0875 for a free estimate.
Why Redlands Residents Choose Us for CertainTeed Service
We’ve spent years tearing into CertainTeed shingle roofs across Redlands, so we can diagnose a baked, brittle Landmark or a leaking underlayment beneath a preserved tile field faster than a generalist ever could. We also provide CertainTeed service in Mentone. Because we’re independent, we don’t have a manufacturer’s quota to hit. If the fix is a repair, we’ll say so. Noel Fierro, our owner, grew up watching San Bernardino County build itself out and learned early that the roof is the one thing you can never ignore. That’s why we carry seven major roofing brands, including CertainTeed, and match the material to the home rather than pushing one product line. We use OEM shingles where the profile is still available, and proven flashing and underlayment when OEM isn’t justified. Redlands homeowners call us because we give them a straight answer, not a sales pitch.

Common CertainTeed Roofing Problems We Solve in Redlands
- Landmark and Presidential shingles baked brittle on east-side tract homes. Repeated 150°F-plus summer cycles turn architectural shingles into something closer to potato chips. The first Santa Ana wind event granule-sheds or creases tabs and exposes fasteners. We see this constantly in the 92374 subdivisions.
- XT 25 and XT 30 three-tab shingles cracking along tab lines. On 1960s-1980s tracts near the 92374 area, the original 1970s underlayment has dried out beneath the shingles. The tabs curl at the rakes and split. The shingles aren’t always the root problem, the dead underlayment underneath is.
- Leaks masked by layered-over roofs. Redlands homes on a second or third roof often have old shingles layered over the original. Once we strip a second or third roof, we find the original underlayment failed and deck rot at the eaves and valleys. The leak was hiding behind two generations of material.
- Sun-baked sealant and flashing at clay tile valleys and penetrations. On tile roofs where CertainTeed shingles were tucked at valleys and penetrations, the sealant dries out and the flashing separates. The dry months hide it. The first winter rain finds it.
- Granule loss and exposed fasteners after Santa Ana wind events. Fall winds in Redlands test every fastener and flashing on a roof. Architectural shingles that have been cooked all summer shed granules fast when the wind hits.
CertainTeed Service in Redlands: What Local Conditions Mean for Your Equipment
Redlands’ historic overlay around downtown and Smiley Heights means a lot of original clay tile is still sitting over its first underlayment. That underlayment wasn’t designed to last 80 or 100 years, and when it fails, the fix is lifting and resetting the tile rather than replacing it. So a CertainTeed shingle repair often turns into a tile-underlayment job at a valley or penetration. We were called out to a Smiley Heights Craftsman where a ceiling stain showed up after the first November rain. The field tile looked fine, but the CertainTeed shingles tucked at the valleys were baked brittle and the sealant had failed. We lifted the original, replaced the failed underlayment and flashing, and reset the tile without disturbing the field. On an east-side 92374 tract home we found only original XT 25 three-tab and 1970s underlayment, so we stripped the failed valley, went back with CertainTeed Landmark architectural shingles matched to the existing exposure, and walked it dry before the next Santa Ana wind test. CertainTeed sales & service means knowing both worlds of Redlands roofing, not just one.
CertainTeed Models & Products We Service in Redlands
We work on the full CertainTeed residential lineup: Landmark architectural shingles, Presidential Shake luxury shingles, XT 25 and XT 30 three-tab shingles, and Grand Manor luxury slate-look shingles. For the lines still in production, such as Landmark and Presidential, we match profiles and colors with OEM shingles. When OEM isn’t justified, we use quality flashing, underlayment, and vent boots from proven suppliers. We keep common Landmark colors stocked for fast turnaround on Redlands repairs and CertainTeed repair in Loma Linda, especially the east-side tract homes. If the shingle field is sound, we repair rather than sell you a whole CertainTeed replacement. That’s the honest call.

AfterCertainTeed Service Pricing in Redlands
CertainTeed repair pricing in Redlands depends on what we find once we get on the roof. A valley or penetration repair on an architectural shingle roof typically runs less than a full tile-underlayment replacement at a historic Craftsman, which involves lifting and resetting original clay tile. The condition of the existing underlayment, the number of layers we need to strip, and the deck repair at the eaves all drive the final number. A free estimate includes a full roof inspection, a written line-item quote, and an honest recommendation on repair versus replacement. Redlands service area homeowners can call (866) 942-0875 to schedule theirs.

FAQs – CertainTeed Roofing in Redlands
Yes. The leak is almost always in the failed underlayment or dried-out sealant at the valley, not in the tile itself. We lift and reset the original tile, replace the underlayment and flashing beneath it, and leave the field undisturbed. Call (866) 942-0875 for a free inspection and exact quote.
The shingles have likely baked brittle after decades of 150°F-plus summers, and the original 1970s underlayment beneath them has dried out. The Santa Ana winds expose fasteners and the first rain gets through. We’ll strip the failed section and assess whether the deck and underlayment are sound or need replacement before we re-shingle. Estimates are free, call (866) 942-0875.
They hold up better than three-tab, but repeated extreme heat cycles still granule-shed and crease tabs over time. We see this in Colton CertainTeed service calls too. The underlayment beneath them often fails first, and that’s what causes leaks. We inspect the full system, not just the visible shingles.
Yes. We match Landmark and Presidential profiles with OEM shingles where the line is still available, and we match XT and Grand Manor profiles as closely as the current market allows. You won’t get a patch that looks like a patch.
It depends on the deck condition and how widespread the failure is. If the rot is confined to a valley or eave, a repair makes sense. If the underlayment has failed across the whole field, a full CertainTeed replacement is the honest call, and we’ll show you why. (866) 942-0875 will get you a straight answer.
