CertainTeed Construction in San Mateo, CA | Ashford Contractors
We provide independent CertainTeed roofing and siding installation across San Mateo, from Hillsdale bungalows to Bay Meadows infill. The thing that separates our CertainTeed work here is the deck prep: so many San Mateo homes sit on bay-mud foundations that have settled unevenly over 60 or 70 years, which means a proper CertainTeed install often starts with re-flashing and flattening before the first shingle goes down. Call (877) 752-3868 for a free estimate, and we’ll tell you exactly what your roof needs and what it doesn’t.
Why San Mateo Residents Choose Us for CertainTeed Service
We’ve torn off enough original 1940s and 1950s roofs in San Mateo to know where they fail first: the rake edges, the valleys, and anywhere someone cut a flashing corner three generations ago. Glen Mossier grew up just over the line in Foster City and trained in construction technology at Skyline College, so he’s been reading Peninsula roof decks since before he could vote. We work with CertainTeed products on their own merits, never as an authorized dealer, and we tell you straight when a CertainTeed system is the right call for your home and when another brand fits better. As an independent CertainTeed sales & service contractor, we can do that without a sales quota in the back of our mind.
We keep genuine CertainTeed starter strips, ridge caps, and Flintlastic underlayment in stock for CertainTeed in Foster City and San Mateo jobs. Mixing brands on a roof voids system-level wind and fire ratings, so we don’t do it. When you call us, we show up with the right components, not whatever the supply house had on clearance.

Common CertainTeed Construction Problems We Solve in San Mateo
- Wind-lift and seal-strip failure on Landmark PRO shingles. San Mateo’s winter storm cycles hit rakes and ridge edges hard, and we regularly find shingles that never sealed because the original installer set fasteners too high in the nail zone. The fix is a targeted reseal or replacement with matching CertainTeed components, not a tube of roofing cement.
- Premature granule loss on south-facing slopes. The combination of salt-laden air near the bay and long summer sun exposure ages CertainTeed shingles well before their rated life, especially on homes in the Shoreview and Parkside neighborhoods. Once granule loss is widespread, patching is a waste of your money and we’ll say so.
- CedarBoards and NorthGate insulated siding distortion. Original 1940s-1960s sheathing in San Mateo’s post-war tract stock expands and contracts with moisture, and siding nailed tight to that sheathing pulls fasteners and warps panels. We see this constantly on homes east of El Camino.
- Underlayment and flashing failures at valleys and penetrations. Atmospheric river events drive wind-blown rain under shingles where Flintlastic or felt was lapped wrong. The result is a leak that shows up two rooms away from the actual problem, and it’s almost always a flashing detail, not a shingle problem.
- Deck sag over settled bay-mud foundations. This is the one nobody talks about. In the flats east of El Camino, roofers routinely find original 1950s and 1960s roof decks over foundations that have settled unevenly. A CertainTeed replacement here often begins with checking deck flatness before tear-off, because new shingles can’t fix a wavy deck.
CertainTeed Service in San Mateo: What Local Conditions Mean for Your Equipment
Here’s the information-gain detail that generic CertainTeed pages never mention: in the flats east of El Camino near the bay, roofers routinely find original 1950s-60s roof decks over bay-mud foundations that have settled unevenly. That means a CertainTeed replacement on those homes isn’t just a tear-off and shingle job. We check deck flatness section by section, re-flash valleys and penetrations, and often re-deck sagged areas before the underlayment goes down. Skip that step and your new CertainTeed system looks wavy from the street within a year and channels water to the low spots. On a 1950s bungalow in the Hillsdale neighborhood, we tore off two layers of aged three-tab and found the original skip sheathing had sagged where the raised foundation had settled, a challenge we also address with CertainTeed in Belmont. We re-decked those sections flat, replaced the rusted valley flashing with new metal, and installed a CertainTeed Landmark PRO system with Flintlastic SA underlayment and matching ridge caps, then added new gutters sized for the bay-facing runoff. That’s the difference between a roof that lasts 30 years and one that fights you from day one. Glen’s rule applies here: build it right the first time, and you won’t be rebuilding it in ten years.
CertainTeed Models & Products We Service in San Mateo
We install and repair the full CertainTeed roofing lineup: Landmark PRO architectural asphalt shingles, Presidential Shake and Presidential Solaris polymer shingles, NorthGate and CedarBoards insulated siding, and Flintlastic SA self-adhered underlayment. On every job we use genuine CertainTeed components because shingle systems are engineered as a system, not a pile of parts. That approach matters in San Mateo’s climate, where fog, salt, and wind don’t forgive shortcuts, and the same holds for our CertainTeed service in Hillsborough. When a repair calls for a few lifted tabs or a localized valley fix, we handle it with matching materials. When the shingles are past granule loss or the seal strips have failed across the slope, we tell you a full replacement is the honest move and explain why a patch would fail again next rainy season.

FAQs – CertainTeed Construction in San Mateo
Yes, with one condition: the deck has to be right before the shingles go on. Raised foundations on San Mateo’s bay mud settle unevenly over decades, and that settlement shows up as subtle waves in the roof deck. We check flatness and re-deck sagged sections before installing CertainTeed products, so the system starts on a solid surface. Call (877) 752-3868 and we’ll inspect your deck for free.
Yes, if the roof is vented poorly and the shingles sit in constant moisture, salt air accelerates granule loss and surface streaking on south-facing slopes. What helps: proper attic ventilation, clean valleys, and a roof deck that’s dry before underlayment goes down. We factor San Mateo’s fog belt into every CertainTeed installation, especially for homes east of El Camino and near the Shoreview area. Call (877) 752-3868 for a ventilation check and exact quote.
It depends on what we find. A few lifted tabs or a localized valley leak usually gets a targeted fix with matching CertainTeed materials. But shingles past granule loss or seal-strip failure across a whole slope need a full replacement, because patches fail again next rainy season and cost you more over time. We’ll tell you which one you need, with photos, so you can see it yourself. Estimates are free, call (877) 752-3868.
Yes. San Mateo runs every project through seismic and environmental review, and roof replacements often trigger a deck inspection and structural check under the city’s codes. We pull the permits, schedule the inspections, and pass them, so you don’t have to navigate the counter at City Hall on your own. For a project in the Hillsdale or Bay Meadows area, call (877) 752-3868 and we’ll walk you through the timeline.
We install Landmark PRO architectural asphalt shingles, Presidential Shake and Presidential Solaris polymer shingles, and Flintlastic SA self-adhered underlayment, plus NorthGate and CedarBoards insulated siding.
