CertainTeed Construction in Redwood Shores, CA | Ashford Contractors
We provide independent CertainTeed roofing and siding service across Redwood Shores, from full replacements to targeted repairs. The thing that sets our CertainTeed work apart here is knowing how salt fog and engineered fill interact with specific CertainTeed products, not just how those products look in a showroom. Call (877) 752-3868 for a free estimate. As an independent contractor, we bring product expertise without any manufacturer affiliation.
Redwood Shores sits on reclaimed bayfront land, built mostly in the 1980s and 90s when Mediterranean-style homes with tile roofs and stucco walls went up over former salt ponds. That history shapes every Home Remodeling – Redwood Shores project we do here, and it’s why our approach differs from a generic CertainTeed service call.
Why Redwood Shores Residents Choose Us for CertainTeed Service
We’ve installed and repaired CertainTeed systems across the Peninsula long enough to know what fails in this specific microclimate. CertainTeed sales & service is one of the six roofing manufacturers we work with regularly, which means we’re not pushing a single product line. If CertainTeed is genuinely the right material for your Redwood Shores home, we’ll use it. If another brand suits the conditions better, we’ll tell you that too.
Glen Mossier, who owns Ashford Contractors, trained in construction technology at Skyline College and grew up watching CertainTeed in Foster City homes get rebuilt after water damage. That background taught him how Bay Area moisture works its way into a house, and it’s why our CertainTeed work in Redwood Shores always starts with a careful look at what water and salt have already done. We also stock CertainTeed OEM flashings and accessories locally, which shortens repair timelines for Redwood Shores homeowners who can’t wait weeks for parts.

Common CertainTeed Construction Problems We Solve in Redwood Shores
- Corroded flashings and fasteners. Salt-laden air off San Francisco Bay accelerates corrosion on CertainTeed metal flashings and fasteners, especially at roof edges and penetrations. In Redwood Shores, we routinely find valley flashing that has rusted through within fifteen years, far sooner than the shingles themselves. We replace these with corrosion-resistant OEM components sized for salt-air exposure.
- Cracked shake and slate-profile shingles from deck movement. Redwood Shores is built on engineered fill over former salt ponds, and bay mud settlement causes roof decks to shift unevenly. CertainTeed Presidential Shake TL and Symphony Slate are rigid profiles, and when the deck moves beneath them, the shingles crack at stress points. We diagnose whether the deck itself needs reinforcement before installing new material.
- Warped CertainTeed Cedar Impressions siding. Winter rain combined with the shallow attic ventilation typical of 1980s Mediterranean-style homes pushes moisture into siding. CertainTeed Cedar Impressions is a polymer product, but if it was installed without proper vapor management, salt-heavy condensation causes it to warp and buckle. We fix the ventilation first, then replace the affected sections.
- Blistered, granule-shedding shingles from fog. Older CertainTeed organic-mat shingles don’t hold up in Redwood Shores’ persistently damp microclimate. Fog settles on the roof in summer, and the shingles blister and shed granules faster than they would inland. When this happens, we usually recommend a full replacement with a modern fiberglass-mat CertainTeed line like Landmark PRO.
- Leaks at valleys and roof-to-wall junctions. Minor deck settlement pulls flashing away from walls and creates gaps at valleys. In Redwood Shores, these leaks are often not obvious from outside, and we have seen homeowners chase them for years. Our inspections look for the settlement pattern that causes them, then we fix the root issue, not just the visible opening.
CertainTeed Service in Redwood Shores: What Local Conditions Mean for Your Equipment
Most CertainTeed installation guidance is written for stable inland soil. Redwood Shores is not stable inland soil. The entire community sits on engineered fill over old salt ponds, and the ground beneath your roof deck has been settling since your home was built. When a roof deck moves even a quarter inch, rigid CertainTeed profiles like Symphony Slate and Presidential Shake TL respond differently than flexible asphalt shingles. They crack, or the seams open up just enough for wind-driven rain to find a path through. That’s why our CertainTeed installations in Redwood Shores regularly include reinforced underlayment and adjustable flashing details that allow for continued minor movement without breaking the roof’s water barrier. We see this pattern most often in the older neighborhoods near Redwood Shores Elementary and along the canals, where the fill has had more decades to consolidate and where soil conditions vary noticeably from one lot to the next. A roofer who treats this as a standard asphalt job will be back in five years. We build the roof to stay put.
CertainTeed Models & Products We Service in Redwood Shores
We work on the full CertainTeed roofing and siding range installed across Redwood Shores: Presidential Shake TL for luxury shake profiles, Landmark PRO for the heavy-duty architectural shingle line most common in local re-roofs, Symphony Slate for rigid slate-look roofs, and Cedar Impressions Siding for exterior facades that need the look of wood without the rot. On every repair, we use CertainTeed OEM flashings, ridge caps, and starter strips where system integrity depends on them. For generic components like fasteners and sealants, we select high-quality aftermarket equivalents rated for salt-air exposure. We’ll always give you a straight repair-versus-replace assessment, because sometimes a targeted repair with the right OEM parts is smarter than a full tear-off.

FAQs – CertainTeed Construction in Redwood Shores
Salt fog from San Francisco Bay accelerates corrosion on metal flashings, fasteners, and edge details. It doesn’t harm the shingles themselves as quickly, but the metal components that keep water out rust years earlier than the roofing material fails. In Redwood Shores, we recommend corrosion-resistant flashing and periodic inspections every three to five years. Call (877) 752-3868 to schedule one.
Yes, when it’s installed with proper vapor management behind it. The product itself is polymer and won’t rot, but Redwood Shores’ winter rain and shallow attic ventilation can trap moisture behind the siding, which causes warping and buckling. We fix the ventilation and moisture barrier first, then reinstall or replace the siding so it stays flat for decades.
A CertainTeed architectural shingle roof in Redwood Shores typically lasts 20 to 25 years if the underlayment and flashing are done for salt-air conditions. That’s shorter than inland because the fog and salt accelerate metal component wear, not because the shingle fails first. If your roof is in that age range, call (877) 752-3868 for an inspection to see what’s actually degrading.
Yes. Redwood Shores is within the BCDC jurisdiction, and roof replacements can trigger floodplain and Bay-front development rules that don’t apply a few miles inland. We handle the permit paperwork as part of our project scope, and we’ll tell you upfront what’s required before any work starts.
Valley leaks in Redwood Shores are usually caused by roof deck settlement from the engineered fill your home sits on. As the deck shifts, valley flashing pulls away from the shingles and leaves a gap. Patching the shingles won’t fix it permanently because the movement continues. We install adjustable flashing and reinforced underlayment that absorb the movement. Call (877) 752-3868 for an exact diagnosis and quote.

We recently replaced a CertainTeed Landmark PRO roof on a 1980s two-story in Redwood Shores where salt fog had eaten through the valley flashings and deck settlement had cracked the old shingles. After new corrosion-resistant flashing, fully adhered underlayment, and Landmark PRO in a color that matched the stucco, that roof is ready for the next rainy season. If your CertainTeed roof or siding is showing the same signs, call (877) 752-3868 and we’ll come take a look. Build it right the first time, and you won’t be rebuilding it in ten years.
