CertainTeed Construction in Mountain View, CA | Ashford Contractors
We install and repair CertainTeed roofing systems across Mountain View and provide Sunnyvale CertainTeed service as an independent contractor. That means we work with the brand’s full product range and spec sheets without being tied to any manufacturer program. If you’re dealing with a leaking flat roof in 94041 or granule loss on a Landmark roof near downtown, call (877) 752-3868 for a straight answer and a free estimate.
Why Mountain View Residents Choose Us for CertainTeed Service
Our crews have torn into enough CertainTeed low-slope and steep-slope assemblies in the 94040 and 94041 postwar stock to know exactly how their membranes, underlayments, and shingle lines behave under our sun-then-atmospheric-river cycle. We’re authorized to work with 50+ name-brand manufacturers, but CertainTeed is one we know at the failure-point level, not just from a catalog. Glen Mossier, our owner, grew up in Foster City’s Marlin Cove watching lagoon-side homes get rebuilt after water damage. He learned early that good construction is what keeps a house standing through decades of Bay Area weather, and that’s the standard he brings to every Mountain View roof we touch.
We carry CertainTeed OEM accessories: ridge vent, starter strips, Flintlastic primer, DiamondDeck underlayment. Mixing underlayments and adhesives across brands is where most flat-roof callbacks originate, so we don’t do it. When a Landmark field is otherwise sound, we repair and re-flash rather than tear off the whole roof. When a low-slope assembly has aged out, we tell you plainly that patching only buys one more season. That’s the kind of honesty Mountain View homeowners deserve when they’re pricing a multi-thousand-dollar roof decision.

Common CertainTeed Construction Problems We Solve in Mountain View
- Flintlastic SA seam lifting on flat and low-pitch Eichler-style roofs. The self-adhered membrane laps and fishmouths where ponded water sits through winter storms. Mountain View’s mid-century flats are especially prone because original drainage was never sized for today’s atmospheric-river rainfall. We re-prime and re-lap seams, then add tapered drainage detail so water sheds instead of standing.
- Landmark shingle granule loss on south- and west-facing slopes. After months of rainless summer sun, the seal strips bake and granules start sloughing. The first wind-driven storm pushes water under the shingle course. In Mountain View’s 94040 ranchers, we see this on the same west-facing elevations every autumn.
- DiamondDeck and RoofRunner underlayment wrinkling on post-and-beam decks. Original mid-century open-beam framing moves more than modern sheathed roofs. The underlayment telegraphs through the shingle course and eventually cracks at the wrinkles. This shows up as visible ridge lines on otherwise clean Landmark roofs across Mountain View’s Eichler neighborhoods.
- Flashing failures at skylight curbs and low parapets. The original single-pane glazing units from the 1960s and 1970s were rarely detailed for concentrated storm runoff. Where CertainTeed membrane meets those curbs, water finds the gap. We re-flash with modern CertainTeed-compatible metal and membrane details.
- Valley failures where low-slope meets steep-slope transitions. Mountain View homes built before current code often have valleys that funnel more water than they were designed to carry. When the CertainTeed membrane in those valleys delaminates, the leak travels far from where it enters.
CertainTeed Service in Mountain View: What Local Conditions Mean for Your Roof
Mountain View construction runs through two parallel worlds: the older single-story Eichler and rancher stock south of El Camino and in the 94040 and 94041 neighborhoods, where remodels mean bringing decades-old framing and flat or low-slope roofs up to current Title 24 and seismic rules, and the constant rebuild cycle tied to the North Bayshore tech campus economy. The first world is where most of our CertainTeed work lands, though we also handle CertainTeed in Los Altos Hills. Those flat roofs pond water and fail at seams when the first atmospheric-river storms hit, so roof drainage and flashing detail matter as much as the membrane or shingle you choose.
Because Mountain View permitting runs through the city’s planning and building divisions and land values are so high, roof replacements on the mid-century flats here often get pulled into a broader Title 24 and seismic scope. A CertainTeed re-roof frequently has to document insulation values, drainage calculations, and structural attachment, not just shingle color. We handle that documentation as part of the job because skipping it means the permit stalls and your roof sits open through the next storm. On a postwar rancher off a downtown Mountain View street in 94041, we opened up a Landmark roof with granule loss on the west slope and found the real problem two feet away: ponding at a low parapet where the Flintlastic SA lap had lifted, sending water back under the DiamondDeck underlayment. We re-lapped and re-primed the membrane at the parapet, re-flashed the skylight curb, replaced the failed shingle courses, and added drainage so the next atmospheric river sheds instead of standing.
CertainTeed Models & Products We Service in Mountain View
We install and repair the full CertainTeed roofing catalog, but these are the products we specify and service most often in Mountain View:
- CertainTeed Landmark architectural asphalt shingles, the standard steep-slope choice for ranchers and new infill builds alike.
- CertainTeed Presidential Shake and Presidential TL luxury shingles for homeowners who want a heavier, more dimensional profile.
- CertainTeed Flintlastic SA self-adhered modified bitumen for low-slope and flat roofs, the workhorse membrane on Mountain View’s Eichler-style stock.
- CertainTeed DiamondDeck and RoofRunner underlayments, which we stock locally for fast turnaround on re-roofs and repairs.
We use OEM accessories across the board. When a roof has a CertainTeed membrane, it gets CertainTeed primer, CertainTeed flashing details, and CertainTeed-compatible venting. No mixing, no “equivalent” substitutions that void your material warranty and create callback headaches.

FAQs: CertainTeed Construction in Mountain View
If the membrane is less than 10 years old and the seams are lifting but not torn, a targeted repair is usually the right call: re-prime the laps, re-adhere the membrane, and add drainage detail. If the Flintlastic has been ponding for multiple seasons and the underlayment is wet, patching becomes a stopgap. We’ll inspect and tell you which side of that line your roof sits on. Call (877) 752-3868 and we’ll walk it with you.
Frequently, yes. When you re-roof in Mountain View, you’re required to bring the roof assembly up to current energy code, which often means documenting insulation values and verifying structural attachment. On some mid-century homes, the city also requires seismic upgrades if you’re already into the framing. We handle the documentation and the upgrades as one scope so the permit doesn’t stall.
Long rainless summers bake the seal strip and the granule adhesion layer on south- and west-facing slopes. Once the granules slough off, the asphalt underneath oxidizes and the shingle loses its water-shedding surface. This isn’t a CertainTeed defect; it’s what Mountain View’s specific climate pattern does to any asphalt shingle. The fix is often isolated course replacement before the next storm season. Call (877) 752-3868 for an exact quote – estimates are free.
Yes. CertainTeed color availability from our local suppliers is strong, and because we work with Landmark and Presidential lines directly, we can match both the product and the weathering pattern. On older roofs where the original color has been discontinued, we’ll show you the closest current match and flag it before we order. Matching is a sourcing discipline, not a guessing game.
Roof repair typically runs $400 to $1,800, replacement $8,000 to $20,000, and gutter work $400 to $1,800. Gutters are a separate line item unless we’re already replacing the roof, in which case we usually recommend doing them together so drainage matches the new membrane.
