Why Los Altos Residents Choose Us for CertainTeed Service
We’re a full-scope general contractor, which means the same team managing your CertainTeed roof is also the team that framed the second-story addition beneath it. That single-contract accountability removes the finger-pointing that happens when a roofer blames the framer and the framer blames the roofer. Ken Stafford grew up near the Milpitas BART station and built his construction career starting with formal training at Evergreen Valley College in San Jose, so he reads plans the way a finish carpenter reads grain: he sees where the framing, flashing, and shingle field all have to agree. If you’re in Los Altos and want a CertainTeed roof that integrates cleanly with an existing ranch home or a new ADU, we’re the General Contractor in Los Altos who specs materials by name and installs them as a system.

Common CertainTeed Construction Problems We Solve in Los Altos
CertainTeed makes a solid product line. But in Los Altos, the failure is rarely the shingle itself. It’s what’s underneath and around it.
- Wavy shingle courses over original skip sheathing: Most 1950s – 70s Los Altos ranch homes were framed with skip sheathing and thin deck boards. Once we tear off the old shingle field, we routinely find the deck is the real problem. New CertainTeed Landmark shingles need a solid, flat substrate. Without re-decking, you get wavy courses and fasteners that pull out within a few seasons.
- Sealant-strip failure at rakes and ridges: Los Altos’s dry-summer heat cycles followed by a wet winter put real stress on shingle sealant strips. We see it most where a second-story addition reduced attic ventilation, trapping heat under the CertainTeed field. The shingles at the edges lose their bond first.
- Leaks at wall-to-roof tie-ins on second-story additions: When a new second story goes up and ties into the existing CertainTeed shingle field, the valley and wall flashings are the weak point. We find them inadequately integrated on a regular basis. The leak shows up at the tie-in, not out on the open field.
- Ember intrusion near the foothill edges: Homes on the western edges of Los Altos sit closer to wildland areas. Open eave vents and ridge vents, plus missing fire-rated underlayment, leave an otherwise sound CertainTeed roof short of a Class A assembly. That’s a code issue and an insurance concern.
- Mismatched repair components: We see roofs where a previous repair used generic starter or ridge vent instead of CertainTeed Integrity System components. Mixing brands voids the assembly logic and complicates any future manufacturer claim.
CertainTeed Service in Los Altos: What Local Conditions Mean for Your Equipment
Los Altos planning runs every addition and second-story remodel through discretionary design review. The city has no standard subdivision tract pattern, so what gets built on one street won’t necessarily fly on the next. That means a new CertainTeed roof on a legacy ranch home is frequently the last visible piece of an entitlement process where massing, shadow, and neighbor sightlines were already litigated before the material ever arrived on site. On a 1960s single-story ranch off a wide lot near downtown Los Altos, the owner’s permitted second-story addition left the old CertainTeed shingle field tying into a new wall with a valley that leaked through the first winter, prompting a call for CertainTeed repair in Los Altos Hills. Our crew tore off to the original skip sheathing, re-decked with solid plywood, installed a Class A CertainTeed Landmark assembly with new starter, ridge vent, and properly integrated wall and valley flashing, and the roof has stayed dry through two wet seasons. The point is that in Los Altos, the roof is not just a roof. It’s the cap on a process. And the contractor who understands the process makes better roofing decisions.
CertainTeed Models & Products We Service in Los Altos
We install and repair the full CertainTeed roofing line you’re likely to find on Los Altos homes: Landmark and Landmark Pro architectural shingles, Presidential Shake and Presidential Shake TL, plus NorthGate and Monogram siding. Our crews use genuine CertainTeed Integrity Roof System components, including starter strip, ridge vent, and matching underlayment. We don’t swap in aftermarket parts because the assembly logic breaks and future claims get complicated. For Los Altos homeowners, the most common question is whether a torn-off roof needs re-decking. If the deck is thin or skip-sheathed, the answer is yes, and we’ll show you the boards before we cover them. For full details on the brand, see our CertainTeed sales & service page.

FAQs – CertainTeed Construction in Los Altos
Not always. If the existing shingle field is sound and the deck underneath is solid plywood, we can often integrate the new wall and valley flashings into the current roof. But if the deck is thin or skip-sheathed, and especially if the architectural style review already required changes to the roof geometry, a full tear-off with new CertainTeed Landmark shingles is usually the cheaper long-term move. Call (877) 752-4194 and we’ll tell you which situation you’re in.
Because the shingles were installed over 1950s – 70s era skip sheathing and thin deck boards. CertainTeed repair in Mountain View often starts with the same issue: shingles perform well when the substrate is flat. On these older Los Altos homes, the deck moves and flexes, which causes wavy courses, popped fasteners, and premature wear. The shingle rarely fails first. The deck does.
If your home sits near the western foothill edges of Los Altos, yes, it’s worth upgrading to a Class A assembly. That means the right underlayment, properly designed eave and ridge vents, and CertainTeed shingles rated for the assembly. We’ll check your local code and insurance requirements during the estimate.
Sometimes. Los Altos design review cares about massing, materials, and neighbor sightlines, and depending on your project, the panel or commission may push for a specific profile, like Presidential Shake instead of standard Landmark. We coordinate with the process and can provide the material specifications the city asks for, similar to how we handle CertainTeed repair in Stanford.
For most Los Altos homes, architectural shingles like Landmark Pro are the practical choice. Metal roofing makes sense if you’re chasing a longer service life, a specific architectural look, or better fire resistance on a foothill-adjacent property. We install both. Call (877) 752-4194 for a straight comparison based on your roof.
