CertainTeed Construction in Sunnyvale, CA | Workshop Contractors
We provide independent CertainTeed roofing, siding, and trim service across Sunnyvale – from full Landmark re-roofs on 1950s ranches in 94086 and 94087 to siding and addition tie-ins on the city’s growing number of two-story rebuilds. What makes our CertainTeed work different here comes down to one thing: Sunnyvale’s teardown-and-rebuild economy means most of what we do involves tying new CertainTeed assemblies into older mid-century homes beside brand-new builds, and that’s a detailing problem most contractors never see. Call (844) 384-3361 to talk through your project and get a free estimate.
Why Sunnyvale Residents Choose Us for CertainTeed Service
Workshop Contractors isn’t a manufacturer rep or a single-line shop. We’re an independent general contractor whose crews install and service CertainTeed Landmark, Presidential Shake, Cedar Impressions, Monogram, and Restoration Millwork systems every week on Silicon Valley remodels and re-roofs. That independence means we recommend a repair when a repair makes sense, and a full replacement only when granule loss, deck condition, or flashing failures across the whole roof plane demand it.
Noel Figueroa, our owner, learned framing and finish work the hard way: on job sites before he could rent a truck, with a tradesman grandfather who built the family house in Pomona with his own hands. That background matters when your CertainTeed project involves matching a modern addition to a mid-century slab foundation or re-flashing an open valley that’s been backing up winter rain for years. We don’t guess at intersections. We have built enough of them to know where they fail. For CertainTeed sales & service across Silicon Valley, we’re the crew that documents cleanly for Santa Clara County and Sunnyvale plan review.

Common CertainTeed Construction Problems We Solve in Sunnyvale
Here are the issues we see most often on CertainTeed installations around Sunnyvale, and what actually causes them on these specific blocks.
- Granule loss on west- and south-facing Landmark slopes. Sunnyvale’s old ranch rooflines rarely shade their own southern exposures. A Landmark roof on a 94086 bungalow takes full summer sun from 11 a.m. to 7 p.m., and over 15-20 years the granules erode unevenly and the asphalt beneath begins to oxidize. We assess whether the wear is localized enough for a repair or whether the whole plane needs replacing.
- Winter-rain ponding at flat and low-slope transitions. Many original 1950s ranches in 94087 have composition shingles on the main slopes but near-flat sections over carports or sunrooms. Winter rain pools there, and when the underlayment or sheathing was never properly flashed, it rots from the top down. A CertainTeed repair that ignores the ponding zone just buys a year or two.
- Buckling Cedar Impressions and Monogram siding at addition tie-ins. When a new two-story contemporary home goes up next to an original single-story ranch, the older wall now sits in the shadow line of a taller structure, and without a proper expansion joint the CertainTeed siding at the transition buckles or pulls fasteners. We correct those joints and match the siding profile.
- Wind-driven rain backing up at open valleys and wall/roof tie-ins. Sunnyvale storms come off the Santa Cruz Mountains in short bursts, and on a home with an original valley flashing that was never upgraded, the wind pushes water up under the shingle courses. Landmark roofs need the valley and wall tie-in flashed to current code, not to what was acceptable in 1962.
- Delaminated sheathing under tired Landmark roofs. On a tear-off, our crews frequently find soft decking where rain penetrated at an open valley or a failed boot flashing. The shingle was often fine; the decking wasn’t. We replace the deck, not just the surface layer.
CertainTeed Service in Sunnyvale: What Local Conditions Mean for Your Equipment
Sunnyvale’s 94086 and 94087 orchard-tract blocks now mix original 1950s ranches with brand-new two- and three-story builds next door, sometimes on the same parcel line. That’s not a cosmetic fact. It changes how a CertainTeed re-roof or addition has to be detailed. The new build creates a shadow line that alters how fast the older roof dries after rain. It also raises the property-line setback and height questions that Sunnyvale’s planning process cares about, because the city sees these blocks as a teardown-and-rebuild market and holds both the old home and the new one to current code. So when we tie a new CertainTeed roof plane into an original mid-century slab foundation, we’re not just matching shingles. We’re re-flashing wall and valley intersections, checking shear-wall connections, and making sure the new roof plane drains into a system that handles the neighbor’s shadow and the winter rain together. On flat, uniformly aged tracts in other cities, that level of detail never comes up.
A Field Example
On an original ranch in the orchard tracts of 94087, our crew tore off a tired Landmark roof that was shedding granules on the south slope. Underneath, we found soft sheathing where winter rain had been backing up at an open valley. We replaced the decking, re-flashed the valley and the wall tie-in to the neighbor’s new three-story build, and installed a CertainTeed Landmark assembly with fresh underlayment and ridge vent so the roof documented cleanly for Santa Clara County inspection.
CertainTeed Models & Products We Service in Sunnyvale
We work across the CertainTeed product families most common on Sunnyvale homes. The Landmark series – Landmark, Landmark Pro, and Landmark CertainTeed IR shingles – makes up most of the re-roof work we do in 94086 and 94087. We also service Presidential Shake and Presidential TLI on larger contemporary builds where the homeowner wants dimension without the weight of clay. For siding, we install and repair Cedar Impressions and Monogram profiles, plus Symphony and Restoration Millwork trim and fascia.
On the parts front, we use genuine CertainTeed accessories: the manufacturer’s own underlayments, ridge vent, starter strip, and hip-and-ridge. Matching those to the shingle line keeps the manufacturer’s published installation requirements intact. Where decking and flashing perform better as aftermarket products than OEM trim, we say so and install the better part. We stock the common Landmark colors and accessory lines locally so most Sunnyvale projects don’t wait on a shipping lead.

A roof repair on a Landmark roof in Sunnyvale typically lands between $400 and $1,800 depending on how many courses, valleys, and flashing points need attention. A full replacement moves on deck condition: if the sheathing is sound, the cost stays toward the lower end of the range; if we’re tearing off delaminated decking on a flat transition, it climbs. Every estimate we write is a line-item scope, not a single number, and the estimate is free. Call (844) 384-3361 to get one.

FAQs – CertainTeed Construction in Sunnyvale
Yes, in most cases we can match the original Landmark color closely enough that a partial repair on one slope blends with the existing roof, assuming the existing shingles haven’t weathered so far that the color has shifted. When the roof has 15-plus years of full sun exposure on the west or south slope, we may recommend replacing the whole plane rather than trying to match a badly faded section, because a visible patch looks wrong and fails faster. Call (844) 384-3361 and we’ll take a look.
Yes, it typically does. The new two-story build creates a shadow line across your roofline and changes how winter rain drains and dries, and if your property line is close, the addition’s wall and roof tie-ins now interact with theirs. We check the flashing at the property-line wall, look at the valley drainage, and make sure the new roof plane or addition is detailed for our Mountain View CertainTeed service and Sunnyvale’s setback and height codes before we pull the permit. A simple re-shingle won’t solve the bigger interaction.
Often, no. Landmark shingles are designed for sloped roofs, and on a near-flat section over a carport or sunroom in Sunnyvale’s older ranches, the water ponds long enough to penetrate even a fresh shingle assembly. Those sections usually need a low-slope product or a proper underlayment and flashing detail underneath the shingles. We’ll tell you if the low-slope section needs a different approach before we quote the shingle work. Call (844) 384-3361 for an exact scope.
Yes. We install and repair Cedar Impressions and Monogram siding, including the expansion-joint and fastener corrections needed when a new two-story addition sits beside an original single-story wall. The siding part of a Sunnyvale remodel is usually simpler than the roofing interaction, but we do both under one contract as CertainTeed specialists, which means you’re not coordinating a siding contractor and a roofer separately.
Yes. Our installations are documented to pass Sunnyvale plan check and Title 24 review, and we keep the manufacturer’s published installation requirements intact by matching the shingle line to its own underlayments, starter, and ridge vent. We don’t claim any manufacturer authorization for our Santa Clara CertainTeed service – we’re independent – but our paperwork supports what the inspector needs to see.
