Call 6504145505What We Bring to Every Cupertino Roof
- Licensed & insured, with the paperwork available before any ladder goes up on your roof.
- A free, written roof estimate that lists the tear-off, the underlayment, and each flashing line separately so nothing hides in a single lump sum.
- A building code check before materials are ordered, including the ventilation and eave protection your roof is required to have.
- Self-adhered ice-and-water shield at every eave and valley, ring-shank nails on the starter course, and hand-sealed valleys rather than sprayed sealant.
- A roofing square count and a material list matched to your actual roof area, so you are not paying for a square that never gets installed.
- Photo documentation at the roof inspection, from the anchor point to the ridge, so you see what we see above your ceiling.
- Full debris hauling to the dumpster plus a magnet sweep of the lawn and driveway at the end of each workday.
- One point of contact from the first roof inspection through the final walkthrough, and a straight answer about when a repair beats a replacement.
Roofing in Cupertino
Cupertino sits on a weather split that shows up the moment we open a roof deck. Summers run dry with almost no rainfall and hard sun on the west slope. Winter storms arrive fast and drop a lot of water in a short window. Marine layer fog keeps the mornings damp long enough for algae to grab hold on north-facing planes.
- Mid-century ranch homes from the 1950s-1960s — shallow roof pitch, three-tab shingle surfaces near end-of-life wear, and fascia boards that have already been caulked twice.
- Contemporary suburban single-family homes built in the 1970s-1980s — original tar paper underlayment beneath the field course, plus pipe boots that have cracked and started to seep.
- Modern luxury estates and newly renovated properties — low-slope sections over garages and dormers where the membrane detail, not the shingle above it, decides whether the roof leaks.
- Vallco and the Tantau Avenue district — older roofs with parapet walls, scuppers, and coping that need resealing before the rains return.
- De Anza and the Stevens Creek area — mature tree cover drops debris into gutters and downspouts, so water backs up at the eave and wicks into the sheathing.
- Sunnyvale-Saratoga Road corridor and the Homestead Road area — a mix of concrete tile, clay tile, and standing-seam panel roofs where fasteners and flashing fail long before the field does.
Same city, four different repair plans. We write the estimate to match the house, not a template.
What roof-maintenance Includes
A real maintenance visit is a roof inspection with a written scope of work, not a sales pitch. We walk the rooftop, check the attic for daylight and moisture, and photograph every defect before anyone quotes a roof estimate.
Then the work itself: reseal chimney flashing and counter-flashing, replace cracked pipe flashing, re-bed ridge cap, clear debris from valleys and gutters, and re-nail any lifted shingle or metal panel edge.
- Inspection of ridge, hip, valley, rake, and eave conditions
- Attic check for ventilation, insulation, and vapor barrier issues
- Sealant and roof cement repair at flashings and penetrations
- Gutter and downspout clearing, plus drain flow check
- Photographic claim documentation for storm damage
Cleanup matters as much as the repair. We tarp the landscaping, run a magnetic sweep for nails, and haul debris off in a dumpster — no fasteners left in the grass.
Quality & Materials Standards
Material choice should match the slope, the substrate, and the exposure. Steep gable and mansard sections handle architectural shingle, wood shake, or clay tile well. Low-slope and flat areas need membrane — TPO, EPDM, or modified bitumen over a sound roof deck.
We check the substrate before we cover it. Rotted plywood or OSB sheathing gets replaced, not buried. Synthetic underlayment and ice-and-water shield go down at valleys and eaves, because felt and tar paper alone won't survive a heavy winter storm cycle.
Every repair is built to current building code, with drip edge, proper fasteners, and ridge vent or soffit vent airflow so the attic breathes. Poor ventilation cooks a roof from underneath and shortens its life regardless of material.
On insurance claim work, we document wind damage and hail damage with photos and measurements, then meet the adjuster on site. You pay your deductible; we handle the supplement and proof of loss paperwork so depreciation and replacement cost are argued correctly.
Common Roofing Issues in Cupertino
Cupertino roofs take a hard one-two punch. Months of dry sun bake the mat under the granules and dry out the sealant at every penetration, then winter storms push water into each opening that sealant was holding shut. Add fog-damp north slopes and mature tree cover, and the failures we find are predictable.
- Granule loss and end-of-life wear — asphalt shingle and three-tab shingle surfaces thin and flake, exposing the asphalt and bitumen underneath to UV. Ignore it and the next wind event tears the shingle loose.
- Cracked pipe boot and vent boot collars — the rubber collar around a pipe flashing splits after years of sun, water wicks down the pipe, and a ceiling stain shows up two rooms away.
- Lifting chimney flashing and counter-flashing — where masonry meets the field course, the apron flashing pulls away and water seeps behind it, rotting the rafter tails and fascia below.
- Backed-up gutters and downspouts — leaf debris dams the gutter, water ponds at the eave, and even a properly laid ice-and-water shield can only hold so much.
- Soft roof deck and sheathing — sag and decay show up as a spongy step in the attic. By then the plywood or OSB panels need replacing, not a patch over the top.
- Valley and rake erosion — the valley carries the heaviest water load on the roof, and worn valley metal gives out first, eroding the decking beneath the field course.
- Parapet and scupper leaks on low-slope sections — flat areas over garages pond water. Once a TPO or EPDM membrane has oxidized, it needs a recoat or full replacement before the next rainy season.
Our Roofing Services in Cupertino
Every job in Cupertino starts the same way: a free roof inspection on the roof and in the attic, then a written, line-item roof estimate you can read without a translator.
- Roof repair — we mend cracked flashing, reset lifted courses, and reseal valleys and roof cement joints before the next storm front.
- Roof replacement — full tear-off to the deck, new synthetic underlayment, then architectural shingle, standing-seam panel, or concrete tile depending on pitch and budget.
- Roof inspection — we check ridge vent and soffit vent airflow, attic fan function, and insulation moisture, because ventilation problems rot the deck from the inside out.
- Emergency roof repair — tarp and stabilize after storm damage, then schedule the permanent fix instead of living under a blue tarp all winter.
- Gutter repair and gutter installation — reseal seams, reset hangers, and extend downspouts so runoff clears the fascia and foundation.
- Metal roofing — standing-seam panel and corrugated panel for low-slope sections, awnings, and canopy roofs that shingle cannot handle.
- Slate, cedar shake, and tile roofing — wood shake and cedar shake replacement, slate repair, and clay tile or concrete tile resetting with proper breakage allowance.
- Roof coating and commercial roofing — reflective coating over a built-up roof or modified bitumen surface, plus TPO and EPDM membrane work on flat rooftops.
- Insurance claim assistance — photo documentation, adjuster inspection support, and help assembling a supplemental claim when the first scope misses damage.

Cupertino Roofing — Frequently Asked Questions
How much does a roof replacement cost in Cupertino?
It depends on square footage, roof pitch, and what is hiding under the old surface. Tearing off three-tab shingles on a simple gable costs far less than replacing clay tile on a roof with dormers and three valleys. We hand you a free, itemized estimate so you can see where the money actually goes.
How long will a roof repair take?
Most repairs, like flashing, pipe boots, or a handful of cracked field courses, finish in a single day. A full tear-off and replacement on a mid-century ranch usually runs two to four days when the weather cooperates. We keep the dumpster staged so your driveway stays usable.
Will my insurance cover storm damage?
Sometimes. Wind uplift, hail damage, and leaks traced to one storm event are often covered. Wear, rot, and end-of-life failures usually are not. We photograph what we find and can walk your adjuster through the roof when they come out.
When is the best time to schedule roof work here?
Late spring through early fall, while the dry season gives us a clean window and predictable cure times. That said, we run emergency roof repair year-round. If water is coming in during a winter storm, call 650-414-5505 and we will tarp it.
Do you work on tile, slate, and cedar shake roofs?
Yes. We reset clay tile and concrete tile, mend slate, and replace wood shake and cedar shake where it has decayed. Tile and slate need a different footing, fastening plan, and breakage allowance than asphalt shingle, and we price them that way.
What is the first sign my roof needs attention?
Granules collecting in the gutter, a brown stain spreading on a ceiling, or a soft spot underfoot in the attic. Any one of those means it is time for a roof inspection, well before the next rain arrives.
