CertainTeed Construction in Hillsborough, CA | Ashford Contractors
We provide independent CertainTeed service in San Mateo County, including Hillsborough, handling everything from single-plane repairs to full roof replacements on the town’s large-lot estates. The thing that makes our CertainTeed work different here is that we plan for what Hillsborough’s review process and terrain actually demand: hillside grading, tree root-zone protection, and drainage tie-ins often decide the budget before the first shingle goes down. We buy direct from CertainTeed’s product lines and follow their published installation specs, and we’re an independent contractor, not manufacturer-affiliated or authorized. Call (877) 752-3868 for a free estimate.
Why Hillsborough Residents Choose Us for CertainTeed Service
Our team has installed and repaired CertainTeed Landmark, Presidential Shake, Monogram, and Cedar Impressions systems across the Peninsula for years, so we know how these products hold up on Hillsborough’s wooded, sloped lots. We’re not learning on your roof. Glen Mossier, our owner, trained in construction technology at Skyline College and spent two decades on structural remodels and additions around San Mateo County. He knows that a roof system lives or dies by its substrate, flashing, and ventilation, not just the shingle. Hillsborough homeowners call us because we treat every CertainTeed job as a system: decking condition, underlayment, starter course, ridge vent, gutters, and drainage all get checked before we quote. We use genuine CertainTeed shingles, siding panels, and accessories where the brand system matters for warranty coverage, and quality aftermarket flashing and fasteners where spec allows. If you’re weighing repair versus replacement, we’ll give you the honest call, not the upsell. Our full CertainTeed sales & service work covers everything from single ridge repairs to complete tear-offs.

Common CertainTeed Construction Problems We Solve in Hillsborough
CertainTeed makes solid products, but Hillsborough’s specific conditions expose predictable failure modes. Here’s what we see most often:
- Landmark granule loss and curling on south- and west-facing ridge slopes: Hillsborough’s dry summers bake those exposures, and many older custom homes have undersized attic venting. The shingles lose granules, then curl at the ridge. We strip and re-nail to current specs, add ridge vent, and the problem doesn’t return.
- Presidential Shake tab lift and fastener back-out on steep pitches: Tree-covered lots drop debris that traps moisture, and wind uplift concentrates at the ridge. On steep Hillsborough roofs, that means tabs lift and fasteners work loose. We see it regularly on the lower Greensborough-area ridges.
- Cedar Impressions and Monogram siding panel buckling: Sun-exposed gable ends on Hillsborough homes expand and contract hard. Panels butt tight against fascia with no expansion gap, and they buckle. The fix is re-installation with proper gaps, not just caulk.
- Moisture wicking and algae streaking at the eave line: Heavy tree shade plus clay-heavy soil splash keeps the lower courses wet long after winter rains end. The roof isn’t failing, but it looks bad and holds moisture. We clean, assess, and rebuild gutters and downspouts to move water off the slope.
- Undersized or failing gutter systems on sloped lots: Hillsborough’s hillside lots shed water fast. When gutters can’t handle it, water backs up under the eave and rots the fascia. We install full CertainTeed gutter accessories sized for the actual roof area, not a generic 5-inch standard.
CertainTeed Service in Hillsborough: What Local Conditions Mean for Your Equipment
Here’s the thing about Hillsborough that doesn’t show up in a product brochure. The town’s Planning and Architecture review can approve a rebuild while excavation still stalls on hillside grading, tree root-zone protection, and drainage. On the wooded ridges, the roof-over-structure and gutter tie-in often decide the budget before a single shingle is laid. We’ve seen this on lots off the lower Greensborough ridges: an approved design, a signed contract, and then a stop-work because a heritage oak’s root zone extends under the proposed downspout run. For CertainTeed owners, that means your roofing contractor has to think like a site contractor. We sequence the work so drainage is resolved before roofing starts, we coordinate with the arborist when trees are near the eave line, and we spec gutter and downspout runs that move water away from clay slopes, not onto them. On a steep, oak-shaded lot we handled recently, our crew stripped a failing Landmark roof, re-nailed to current specs, added ridge vent, and rebuilt the gutters to carry water off the clay. The homeowner avoided a full siding replacement because the shaded eave streaking was surface-only. That’s the sequence Hillsborough demands: drainage first, roof second, and no surprises at excavation.
CertainTeed Models & Products We Service in Hillsborough
We work with the full CertainTeed residential line: Landmark and Landmark Pro architectural asphalt shingles, Presidential Shake TL and Solaris, Monogram vinyl siding, and Cedar Impressions polymer shake siding. For repairs, we use genuine CertainTeed shingles, siding panels, and accessories including ridge vent, starter, and ice-and-water membrane. We stock the common Landmark colors locally so Hillsborough repairs don’t wait on a distribution order. For hail or tree-damaged roofs, we repair if the field shingles are sound and the damage is localized. Once granule loss or tab failure spreads across whole planes, replacement is the honest call. We also handle tile roofing and full gutter and accessory systems, which matters on Hillsborough lots where roof drainage and slope stability are the same conversation.

CertainTeed work in Hillsborough runs a wide range because lot conditions vary so much. A straightforward ridge repair on a flat, accessible roof is a different job from a steep, tree-shaded tear-off that needs drainage coordination and tree protection. Here’s what we typically see across the Hillsborough market:
| Service | Price Range |
|---|---|
| Roof Replacement | $8,000 – $20,000 |
| Roof Repair | $400 – $1,800 |
| Tile Roof Repair | $600 – $2,500 |
| Metal Roof Installation | $15,000 – $40,000 |
What drives the cost: roof pitch, number of planes, decking condition, whether we’re coordinating with tree protection or drainage work, and which CertainTeed line you choose. A free estimate includes a full inspection, written line-item breakdown, and an honest repair-versus-replace recommendation. Call (877) 752-3868 to schedule yours.

FAQs – CertainTeed Construction in Hillsborough
Yes, and we do it regularly. The key is sequencing: we resolve drainage and tree root-zone protection before roofing starts, and we coordinate with your arborist when heritage trees sit near the eave line. Landmark is a good choice for Hillsborough slopes because it handles steep pitches well when properly fastened and vented. Call (877) 752-3868 to walk through your lot’s specific constraints.
We install to CertainTeed’s published specs, so the manufacturer warranty applies to the materials. As an independent contractor, we are not authorized or sponsored by CertainTeed, and we don’t administer their warranty program. What we do offer is a workmanship warranty on our installation, and we’ll document everything so your CertainTeed material claim is clean if you ever need to file one.
Curling and granule loss at the ridge, especially on south- and west-facing planes, is almost always a ventilation and fastening problem. Hillsborough’s dry summers bake those exposures, and older custom homes often have undersized attic venting. The shingle overheats, granules slough, and the tab curls. We re-nail to current specs and add ridge vent, which usually stops the failure in place before it spreads.
That panel buckling is typically thermal expansion, not a product defect. Hillsborough’s sun-exposed gable ends expand hard during dry summer stretches, and if the panels were originally installed tight against fascia with no expansion gap, they have nowhere to go. The fix is removing and re-installing with proper gaps, not caulk. Call (877) 752-3868 for an exact diagnosis on your home.
No. Dark streaking on shaded Hillsborough roofs is algae growth, usually where tree canopy and clay-heavy soil splash keep the lower courses damp long after winter rains. It’s cosmetic, not structural, and it isn’t a CertainTeed material failure. We can clean it and rebuild gutters and downspouts to keep water moving off the slope, which is the actual fix. A free estimate will tell you if it’s surface-only or something deeper.
