CertainTeed Construction in San Francisco, CA | Ashford Contractors
We provide independent CertainTeed installation, repair, and full replacement work across San Francisco, from reroofs to siding and fence reconstruction, including Mission District CertainTeed service. The thing that makes our CertainTeed work here different is simple: we know which of their products hold up in the fog belt and which fail early. City-wide coverage, honest OEM-vs-aftermarket guidance, and one project manager for every job. Call (877) 752-3868 for a free estimate.
Why San Francisco Residents Choose Us for CertainTeed Service
CertainTeed makes a wide product line, but it doesn’t all age the same way on a Victorian rowhouse three blocks from the ocean. We have torn off enough 20-year-old Landmark roofs in the Sunset and the Richmond to know exactly where the weak points are. That’s what you’re buying when you call us: product knowledge that only comes from working with the material in this specific climate.
Glen Mossier, our owner, learned early that good construction is what keeps a house standing through decades of Bay Area weather. He grew up watching lagoon-side homes in Foster City get rebuilt after water damage, and he’s spent two decades since then focused on structural integrity, square framing, and material selection that actually performs. Build it right the first time, and you won’t be rebuilding it in ten years. That’s how we approach every CertainTeed job in San Francisco.
Call (877) 752-3868 and we’ll put an inspector on your roof or fence line, usually within the week.

Common CertainTeed Construction Problems We Solve in San Francisco
- Landmark shingle granule loss and algae streaking on north-facing roof planes. In San Francisco’s fog belt, north planes stay damp for weeks at a time. We regularly see Landmark roofs where the south side looks almost new and the north side is bare of granules and streaked black. The fix is localized replacement when it’s a few shingles, full replacement when it’s widespread.
- Presidential Shake tab cracking and seal failure on low-slope additions. Victorian rear additions and flat-roof dormers often have just enough slope for shingles but not enough for good drainage. Repeated wet-winter/dry-summer cycling cracks tabs and breaks seals. We reflash and repair where damage is isolated, and we tell you honestly when the roof’s geometry calls for a different product.
- Bufftech vinyl fence posts bowing and panels yellowing. San Francisco’s persistent marine moisture combined with real UV exposure is hard on vinyl. We see Bufftech sections abandoned mid-install or completed by someone who skipped concrete depth. Post replacement, panel matching, and full fence rebuilds are all in our scope.
- Monogram siding caulk-joint failure and hidden rot at the sheathing. On Edwardian walls with no housewrap behind the siding, water gets in at failed caulk joints and sits against old growth redwood sheathing. By the time you see cracking at the surface, the rot behind it is usually worse. We remove, inspect, and repair the envelope, not just the siding face.
- Gutter and downspout failure tied to dense rowhouse conditions. Closely built San Francisco homes shed water into narrow side yards and onto neighbor foundations. CertainTeed roofs need properly hung gutters to move water off the structure, and we install and repair them as part of every roof job.
CertainTeed Service in San Francisco: What Local Conditions Mean for Your Equipment
Most San Francisco homeowners never think about geology until it changes their project. But because much of the city, including the Marina, South of Market, and the eastern waterfront, sits in mapped Liquefaction Zones under the Seismic Hazard Mapping Act, a reroof or addition that adds real weight up top can trigger a geotechnical look at the foundation below. That changes how we sequence CertainTeed roof work here. Before we add a third layer of shingles or upgrade to heavier Presidential TL, we check whether the site is in a mapped hazard zone. If it is, we sequence the project so any foundation or shear-wall work gets done before the new roof load goes on. It saves homeowners from doing the roof twice. On a 1908 Edwardian where we handled CertainTeed repair in Noe Valley, that sequencing mattered: we tore off a 20-year-old CertainTeed Landmark roof that had streaked and lost granules on its fog-shaded north plane while the sun-facing side still looked fine. We replaced it with new Landmark shingles over a fresh synthetic underlayment, rebuilt the rotten fascia at the rear addition, and hung new gutters. Because the block was densely packed, we scheduled the tear-off around the rain windows the owner’s neighbors were also watching. That’s what construction in San Francisco actually looks like.
CertainTeed Models & Products We Service in San Francisco
We work on the full CertainTeed residential line: Landmark architectural asphalt shingles, Presidential Shake and Presidential TL luxury shingles, Monogram siding, and Bufftech vinyl fencing. For repairs, we match CertainTeed OEM shingles, ridge caps, and siding accessories whenever the manufacturer’s color and profile integrity matter. Where the original product isn’t available or a better option exists, we use quality aftermarket underlayment, fasteners, and flashing rather than forcing an OEM match that won’t outlast what’s already failing. Given San Francisco’s rain and fog windows, we keep common Landmark colors and Bufftech replacement components staged locally for faster turnaround, and our broader CertainTeed sales & service capability means we are not starting from zero on any job.

FAQs – CertainTeed Construction in San Francisco
Yes, in most cases. Sitting in a mapped Liquefaction Zone doesn’t stop a reroof, but it can trigger a geotechnical review if the new roof adds significant weight or if the project includes a rear addition. We check the hazard mapping on every San Francisco job and sequence the work so the foundation gets looked at before new load goes on. Call (877) 752-3868 and we’ll check your address.
Granule loss on one side of your roof is almost always exposure. In San Francisco, north-facing planes stay damp in the fog belt and algae takes hold, breaking down the shingle surface while the south side dries out and stays intact. It’s not a manufacturing flaw. It’s the local climate, and it means the wet side will fail years before the dry side. We’ll give you an honest read on whether repair or replacement makes sense.
We can do either, depending on condition. Yellowed panels that are structurally sound can sometimes be cleaned, but bowed posts usually mean the concrete footing was too shallow or the post wasn’t sleeved properly. We replace posts where the structure failed and match replacement panels where the manufacturer’s color profile is still available. If the fence is 15-plus years old and failing across multiple sections, replacement is usually the better spend.
It shortens the workable window. San Francisco’s wet winters confine roof tear-offs and replacements to breaks in the rain, and we schedule around forecast windows rather than committing to dates that could leave your decking exposed. We build our San Francisco calendar around the dry stretches from late spring through early fall. Call (877) 752-3868 to get on the schedule before the season fills up.
A full CertainTeed Landmark roof replacement in San Francisco typically runs $9,440 to $23,600, depending on roof size, slope, access for tear-off, and how much decking and fascia needs rebuilding. Densely packed rowhouses and rear additions drive access costs up. The estimate is free, written, and line-itemed, so you’ll know the exact number before any work starts.
