CertainTeed Construction in Palo Alto, CA | Ashford Contractors
We provide independent CertainTeed roofing and exterior construction service across Palo Alto, from full Landmark and Presidential tile and shingle replacements to flashing, underlayment, and gutter repair on homes in every ZIP from 94301 through 94304, and we also handle CertainTeed repair in West Menlo Park. The one thing that makes our CertainTeed work different here is that we plan every job around Palo Alto’s tree protection ordinance, which means a protected coast live oak can dictate staging, debris handling, and even how we sequence the roof itself before a single bundle comes off the truck. If you need CertainTeed work priced correctly for your Palo Alto home, call Ashford Contractors at (877) 752-3868 and we’ll walk the roof with you.
Why Palo Alto Residents Choose Us for CertainTeed Service
We work with CertainTeed’s published installation details and product specifications on every job, and we’ve installed and repaired these systems on Palo Alto homes long enough to know how they actually behave under Bay Area sun and winter rain. That credibility comes from job-site experience with CertainTeed’s steep-slope and low-slope assemblies, not from a manufacturer badge we don’t hold. We’re an independent CertainTeed service provider, which means we answer to you and your roof, not to a corporate rep, and we bring that same independence to our Los Altos Hills CertainTeed service.
Glen Mossier, our owner, grew up in Foster City’s Marlin Cove neighborhood watching lagoon-side homes get rebuilt after water damage. That’s where he learned what happens when flashing and waterproofing details get skipped. He trained in construction technology at Skyline College and has spent two decades applying that to structural remodels and roof assemblies across San Mateo County. When we re-roof a Professorville Tudor or a Barron Park ranch, Glen’s the one checking the deck and the nailing pattern before the first shingle goes down. For CertainTeed sales & service that treats your roof as a system rather than a surface, call us at (877) 752-3868.

Common CertainTeed Construction Problems We Solve in Palo Alto
These are the failures we see most often on CertainTeed roofs in Palo Alto, and each one ties back to a local condition rather than a manufacturing defect. Here’s what we fix:
- Accelerated granule loss and asphalt crazing on west- and south-facing exposures. Palo Alto’s long summer dry season means unshaded south and west roof planes on Landmark and Presidential shingle fields take UV load that grinds the protective granule layer down years ahead of the shingle’s nominal life. You’ll see granules in your gutters and a roof surface that looks dry and cracked. We can assess whether the field still has serviceable life or whether it’s time for a full replacement.
- Flashing and valley failures at chimneys, skylights, and wall transitions. On the 1920s and 1930s Tudor and Craftsman homes in Professorville and downtown Palo Alto, original roof details were never rebuilt to modern CertainTeed flashing standards. Water tracks back under the field, rots the deck, and shows up as ceiling stains inside. We strip the affected area, rebuild the flashing to CertainTeed’s current published details, and re-set the shingle field around it.
- DiamondDeck and Flintlastic low-slope membrane blistering in 94306. Eichler-style and ranch homes in south Palo Alto often carry low-slope roof sections where ponding at drains wasn’t corrected. After enough seasonal wet-dry cycling, the membrane blisters or wrinkles at the seams and splits. We identify where the water is actually sitting, correct the slope where the structure allows, and install Flintlastic SA with proper seam laps.
- Shingle buckling where re-roofs were laid over skip-sheathing without re-nailing. A lot of Palo Alto homes have had one or two re-roofs over the original deck, and if the previous crew laid new shingles over old skip-sheathing or an existing layer without re-nailing to CertainTeed’s current pattern, the field buckles within a few years. We strip to deck and re-nail properly when the deck is sound, which prevents the wave pattern from returning.
- Ridge vent, starter, and hip-and-ridge failures after mixed-part installation. When someone installs CertainTeed field shingles but substitutes aftermarket accessories, the assembly loses its published performance. We see this as premature lifting at the ridge, wind-driven rain entry, and uneven wear along hips. We only install CertainTeed OEM accessories so the assembly works as designed.
CertainTeed Service in Palo Alto: What Local Conditions Mean for Your Equipment
Palo Alto’s tree protection ordinance is the one local variable that changes how CertainTeed work gets done here, and it’s the kind of thing you won’t read on a generic roofing page. The city’s dedicated arborist review means a protected coast live oak on your lot can dictate your roof line before we ever touch a shingle. Overhanging canopies in Professorville and Crescent Park create a staging problem most contractors never face: we have to hand-carry CertainTeed bundles around root-zone exclusion fencing, and debris that would normally fall straight to a tarp and get dragged away has to be netted off the canopy instead. On a Tudor-era home off Bryant Street in Professorville, a protected coast live oak overhung the rear slope, so we staged our CertainTeed Presidential TL bundles by hand outside the arborist’s root-zone fencing and netted debris off the canopy. The old Landmark field on the south slope had lost most of its granules and the chimney flashing had rusted through, so we stripped to deck, re-nailed to CertainTeed’s pattern, rebuilt the flashing and set new Presidential TL with matching hip-and-ridge. That’s the difference between knowing CertainTeed products and knowing how to install them in Palo Alto.
CertainTeed Models & Products We Service in Palo Alto
We install and repair the full CertainTeed roof product range across Palo Alto homes and offer CertainTeed in Emerald Lake Hills. That includes Landmark architectural asphalt shingles on ranches and mid-century tracts, Presidential Shake and Presidential TL luxury shingles on larger custom homes and Professorville rebuilds, and Grand Manor luxury shingles where the architecture calls for a heavier profile. On low-slope sections, we work with Flintlastic SA self-adhered modified bitumen over DiamondDeck underlayment, which matters on Eichler-style roofs in 94306 where the slope is too shallow for shingles.
When it comes to accessories, we use CertainTeed OEM ridge vent, starter, hip-and-ridge, and matching underlayment. Why? Because mixing aftermarket flashing or vent with CertainTeed field shingles voids the assembly’s published performance. A cheap aftermarket ridge vent under a Landmark field might save a few hundred dollars on the front end and cost you a service call and a re-work within two seasons. We don’t take that shortcut, and we won’t recommend you pay someone else to take it either. For Palo Alto service area coverage that respects how CertainTeed systems are designed to work, call us.

What drives the cost on a Palo Alto CertainTeed job? The roof’s square footage, the number of penetrations (chimneys, skylights, vent stacks), whether tree canopy forces hand-carrying and debris netting, and the condition of the deck once we strip the old field.

FAQs – CertainTeed Construction in Palo Alto
Yes, and it changes things before installation even starts. A protected coast live oak triggers Palo Alto’s arborist review, which means root-zone exclusion fencing, canopy debris netting, and often hand-carrying of CertainTeed bundles to the staging area rather than driving a truck or lift across the root zone. We plan the entire roof sequence around the tree, not around the easiest access path. Call (877) 752-3868 and we’ll walk the lot with you and tell you exactly how the tree affects your job.
Realistically, no, not on a fully unshaded south or west exposure. Palo Alto’s summer UV load accelerates granule loss and asphalt crazing on Landmark fields, and we routinely see shingles showing significant wear at fifteen to twenty years that would look much better on a shaded north slope. You’ll still get a solid service life, but the rated life assumes conditions Palo Alto’s sun doesn’t provide. If you want maximum longevity on a brutal exposure, we’ll talk to you about Presidential TL or Grand Manor options. Call (877) 752-3868 for an exact quote on your roof plane.
Yes, and we do it regularly. Eichler and ranch homes in south Palo Alto’s 94306 ZIP often have roof sections with slope too shallow for shingles, which is exactly what CertainTeed’s Flintlastic SA self-adhered modified bitumen over DiamondDeck underlayment is made for. The critical step is correcting ponding at the low-slope drains before we install the membrane, because no product handles standing water forever. We’ll assess your current drainage and tell you if the membrane alone will solve it or if you need slope correction first.
We install new CertainTeed OEM ridge vent, starter, hip-and-ridge, and matching underlayment on every full replacement, and we don’t reuse what’s coming off. On a repair, we match the existing accessories where we can and flag it clearly if the previous crew used aftermarket parts. Mixing aftermarket flashing with a CertainTeed field voids the assembly’s published performance, so we won’t do it. Call (877) 752-3868 and we’ll tell you what’s actually on your roof right now.
It depends on how far into the field’s service life you are. If the flashings are failing on a Landmark or Presidential field that’s twenty-plus years old, a targeted repair might buy you a few years, but you’re paying for scaffolding and staging twice when the field itself goes. If the field is still in its prime and it’s just a chimney or skylight flashing that failed, a repair makes complete sense. We’ll give you both numbers and our honest read on which one is the better spend. Call (877) 752-3868 for a free estimate either way.
