CertainTeed Construction in Pomona, CA

CertainTeed Construction in Pomona, CA | San Mateo Construction

We provide independent CertainTeed roofing and exterior installation, repair, and replacement across Pomona, and the one thing that separates our CertainTeed work here from a generic reroof is how we approach Pomona’s older housing stock first. Before a single bundle goes up, we’re checking what’s underneath the shingles: raised foundations, skipped sheathing, unpermitted citrus-era additions, and tight-to-the-line lot conditions that change what the roof assembly actually has to do. If you’re in 91766, 91767, 91768, or 91769 and considering CertainTeed, call (855) 901-7266 and tell us what the roof is doing right now.

Why Pomona Residents Choose Us for CertainTeed Service

We’ve installed and repaired CertainTeed roofing and siding across Pomona’s 1920s – 1950s bungalows and post-war tracts, as well as handling CertainTeed repair in Montclair, long enough to know how Landmark shingles, WinterGuard underlayment, and Cedar Impressions siding actually behave here – on 90-year-old raised foundations, under 100°F+ inland summer heat, and on lots where the original builder worked tight to the property line. Noel Carrington, our owner, has spent the better part of three decades in residential construction, and he runs our CertainTeed work the way he’d want it run on his own house: with material-level honesty about what the existing assembly can and can’t do. We’re an independent CertainTeed contractor. Not authorized, sponsored, or warranty-backed by CertainTeed. That independence matters because we’ll tell you plainly when a repair buys you another decade, and when it just buys you one more Pomona summer before the leak comes back.

Common CertainTeed Construction Problems We Solve in Pomona

• Valley and step flashing failures on Landmark shingles over old citrus-era additions. Pomona’s pre-war homes were frequently added onto – rear rooms, enclosed porches, lean-tos. Where the original roof plane meets the later addition, rafter movement over decades has opened the deck seams, and the shingle itself is rarely the problem. The flashing detail is. We re-flash the valley and step flashing rather than layering new shingles over a seam that’s already moving.
• Granule loss and premature aging on south- and west-facing slopes. Pomona’s inland San Gabriel Valley heat – often well over 100°F in July and August – is brutal on shingle surfaces, especially where attic ventilation was never upgraded during an earlier reroof. We see Landmark shingles shedding granules on the same slope that gets the afternoon sun, and the fix usually involves both new shingles and a ventilation correction, or that slope fails again.
• Cedar Impressions and vinyl siding wicking at the bottom of pre-1940 wall assemblies. Original Pomona stucco-and-wood homes have no drainage plane. When a later owner added Cedar Impressions or vinyl siding over that assembly, end-grain and nail heads started wicking moisture. We pull the failing runs, assess the original wall substrate, and install with the drainage detail the original builder never had.
• Cracked shingle tabs and popped fasteners where deck sheathing was skipped. On raised-foundation bungalows, undersized or skipped sheathing telegraphs movement directly into the shingle layer. It shows up as cracked tabs and fasteners that work themselves loose. We re-deck the section before re-shingling, because new shingles over a deflecting deck is a guaranteed repeat failure.
• Low-slope rear roofs that were never meant for architectural shingles. Some older Pomona rear additions were built at slopes that are marginal for shingle performance. We add WinterGuard underlayment across those low-slope sections and adjust the assembly, which matters more here than in newer tract homes where every slope was engineered for the product.

CertainTeed Service in Pomona: What Local Conditions Mean for Your Equipment

Pomona sits at the eastern edge of LA County, where a lot of the original pre-1940 housing stock was built tight to property lines, and a meaningful share of those homes now carry unpermitted additions from decades of citrus-era and owner-builder work. That’s the detail most reroof estimates skip, and it’s the one that drives cost, schedule, and whether the job passes inspection. A CertainTeed reroof here routinely starts with as-built verification and permit research, because you can’t assume the roof plane you see matches what’s on the permit at the City of Pomona. On a 1928 craftsman off West Holt Avenue in 91767, the homeowner’s Landmark roof was shedding granules on the south slope after only a dozen years. Tear-off revealed skipped sheathing over the original rafters, plus a rear addition roofed at low slope with no underlayment. We re-decked, added WinterGuard over the low-slope section, and re-shingled with Landmark Solaris to handle the afternoon heat load. The valley leak stopped, and the attic temp came down noticeably that first summer. That’s the kind of thing you only find when you’re actually looking at what’s under the shingles, not just measuring squares from the ground.

CertainTeed Models & Products We Service in Pomona

We work across the CertainTeed line: Landmark architectural shingles, Landmark Solaris for cool-roof reflectance, Presidential Shake and Presidential Solaris luxury shingles, Cedar Impressions and polymer siding, WinterGuard waterproofing underlayment, and DiamondDeck underlayment. On the parts side, we use genuine CertainTeed underlayments, ridge, and starter components where the assembly depends on them – WinterGuard over low slopes, DiamondDeck where deck protection matters. For fasteners and vents, we’re comfortable using quality aftermarket options without compromising the system. What we won’t do is chase a repair that only buys a season. If the deck or flashing is compromised, you need to replace the failing section now, not layer shingles over a problem that’s still moving underneath. We keep common CertainTeed accessories local for faster Pomona turnaround, and we order the rest directly rather than substituting whatever’s on a warehouse shelf.
