Call 6504145505What You Get Before We Touch Your Roof
- A written roof estimate — line items for tear-off, materials, and labor, plus what we are not doing.
- A licensed and insured crew — no unknown labor showing up at your door unannounced.
- Photos of the deck — every soft or rotted board documented before new material covers it.
- Real fall protection — scaffold and a safety harness on two-story work, with ladders set so they aren't leaning on your gutters.
- Clean sites — old shingles pried with a roofing shovel and hauled straight to the dumpster, then a magnet sweep for nails and screws.
- Correct fastening — nail guns set to the right depth, ring-shank nails where wind uplift matters, and hand-sealing anywhere a torch or mastic would fail.
- Honest pricing — if a repair, a reseal, and new caulk hold for a few more years, we won't push a replacement.
- Insurance claim help — a documented scope and photos you can hand an adjuster.
- Ordered by the roofing square — material counted properly, so you don't pay for extra bundles.
Roofing in Gilroy
Gilroy sits in Santa Clara County at roughly 150 feet elevation, and the year splits cleanly in two for a roofline. Dry heat bakes the shingles from spring through fall, then winter fog and heavy rain test every seam and fastener.
- Weeks above 95°F — dry heat cooks asphalt shingle and causes granule loss, and attic temperatures climb until insulation, a ridge vent, and soffit vents are what keep the second floor livable.
- Winter fog and hard rain — water wicks under a lifted drip edge, seeps past the eave and soffit, and rots fascia behind the gutter before you notice anything inside.
- Low humidity and year-round UV — sealant and caulk flake and crack at pipe flashing and counter-flashing, so we reseal boots early instead of chasing a leak later.
- 1960s and 1970s ranch homes in Downtown Gilroy and Rossi — plywood sheathing under three-tab shingle, low pitch, and roof deck boards gone soft near the valley.
- Mid-century farmhouses on larger lots in Leavesley and Uvas — long rake and overhang lines, cedar shake or wood shake on the main roof, and outbuildings where an overlay beats a full tear-off.
- Homes built since 2000 near San Ysidro and Aromas — architectural shingle over synthetic underlayment on hip and gable roofs that shed well until a builder-grade vent boot splits.
- Metal and tile roofs — a standing-seam panel or clay tile roof handles UV far better, and recoating or resealing fasteners costs less than replacement.
What roof-maintenance Includes
A roof inspection starts at the eave and works up. The roofer checks drip edge, soffit, fascia, and every valley for wear.
- Inspect flashing at chimneys, skylights, and dormers
- Test sealant and mastic at pipe boots and counter-flashing
- Clear debris from gutters and downspouts
- Check attic ventilation, soffit vents, and ridge vent airflow
- Re-nail loose fasteners and replace lifted shingles
Repairs follow the scope of work. Crews set a ladder or scaffold, pull damaged shingle with a pry bar, and check the felt beneath.
Synthetic underlayment and ice-and-water shield get replaced where torn. New pipe flashing gets seated in roof cement. Cleanup means a dumpster and a magnet sweep for nails.
Quality & Materials Standards
Material choice tracks the pitch and the substrate. Low-slope sections need membrane — TPO, EPDM, or modified bitumen over a clean deck. Steep gable and hip roofs take architectural shingle or standing-seam panel.
Old farmhouse roofs sometimes carry wood shake or cedar shake. Those demand careful decking inspection before any overlay.
Building code governs every layer here. Ice-and-water shield belongs at the eave and valley. Drip edge protects the rake. Ridge cap and ridge vent close the top.
Honest claims matter more than speed. When storm damage hits, document it with photos before tarping. Your insurance claim needs claim documentation the adjuster can verify.
Know the difference between replacement cost and depreciation. A deductible still applies. A supplement may follow if hidden damage surfaces.
Common Roofing Issues in Gilroy
Roof Problems Gilroy Homeowners Actually Call About
Two things drive most roof trouble here: a dry season that bakes shingles from April through October, and winter fog that keeps a north slope wet for days. Older ranch homes and shaded lots take the worst of it.
- Ceiling stains in a bedroom corner — water intrusion at step flashing or the valley, usually ten feet uphill of the stain; ignore it and the sheathing rots.
- Granules in the gutter and downspout — UV degradation and end-of-life wear on asphalt shingle; the mat dries, splits, and stops shedding water.
- Curled or missing shingles at the rake and eave — wind uplift lifting the starter course; the field course above loosens next.
- A sagging roofline over the garage — overdriven or missed nails, or a rafter that has soaked up moisture, so the decking settles and holds water.
- Moss and algae on the north slope — oak shade plus fog keeps shingles damp, and growth erodes the mat and lifts the tabs.
- A leak at the chimney or skylight — failed counter-flashing covered with mastic that has peeled; water wicks into the framing behind it.
- Soft spots around a pipe boot — cracked rubber and loose fasteners, which drip straight onto insulation and drywall.
- An ice dam along the eave after a hard freeze — rare here, but Mount Hamilton foothill roofs do get it, and we handle ice dam removal and steam ice without prying up good shingles.

- Roof inspection and roof maintenance — a fall check of caulk, sealant, fasteners, and gutter hangers before the rain.
- Emergency roof repair and storm damage repair — tarping and water stops the same day a storm tears a section loose.
- Gutter repair and gutter installation — resealing seams, resetting hangers, and new downspouts where fascia has rotted.
- Chimney flashing and skylight installation — new counter-flashing, apron flashing, and a curb sealed with roofing cement.
- Metal roofing and roof coating — standing-seam panel, corrugated panel, and reflective coating that cuts attic heat.
- Slate, cedar shake, and commercial roofing — flat membrane work in TPO, EPDM, and modified bitumen over occupied buildings.
- Insurance claim assistance — photos, a line-item scope, and a walk-through at the adjuster inspection.
Recent Roofing Projects Near Gilroy
Drip edge and eave — the metal strip at the roof edge that throws water clear of the fascia and gutter; when it lifts, everything behind it gets wet.
Valley and step flashing — where two roof planes meet, or where shingles die into a wall; this is where most Gilroy leaks begin.
Chimney and counter-flashing — masonry moves, metal doesn't, so we cut new flashing and seal it rather than smearing mastic over a gap.
Ridge cap and ridge vent — caps close the top of the roof while the vent lets hot attic air escape; both fail at the same nails.
Pipe boot and boot flashing — the rubber collar around a vent pipe cracks in the sun, and water runs straight down onto insulation and drywall.
Ice-and-water shield and underlayment — the self-adhered layer at eaves and valleys that backs up shingles where snow or ponding water sits.
Skylight and dormer curbs — curbs need apron flashing and a sealed sill; a dormer face takes wind and rain on two sides at once.
Parapet, coping, and scupper — flat and low-slope roofs shed water through a scupper, and cracked coping lets it into the wall instead.
Gutter and downspout — a loose hanger or a clogged downspout pushes water back under the eave and into the fascia board.
Rafter, truss, and ridge beam — the framing under the sheathing; a wet rafter or joist will sag, and a sagging roofline means decking that ponds water.
Purlin, batten, and counterbatten — the grid under tile and slate; rot there drops tiles and opens the roof to water intrusion.
Snow guard and roof anchor — hardware we install for foothill winters and for tying off a safety harness during roof work.
Gilroy Roofing — Frequently Asked Questions
Does San Jose Roof Repair serve Gilroy?
Yes. We're a licensed, insured San Jose roofing contractor that runs crews into Gilroy, from Downtown Gilroy out to Uvas and Aromas. Call 6504145505 and we'll schedule a free roof inspection and a written roof estimate.
What drives the cost of a roof repair in Gilroy?
Access, roof pitch, and how much decking has rotted under the leak. A flashing reseal and a valley rebuild sit at opposite ends of the range, so we hand you a line-item estimate before any work starts.
How long does roof replacement take on a Gilroy ranch home?
Most single-story ranch homes here are a two-day tear-off and install when the sheathing is sound. Replacing rotted plywood or OSB boards adds a day, and we never cover a soft substrate.
Will insurance cover storm damage to my roof?
Often, if the damage came from one dated storm. We photograph the damage, write the scope your adjuster needs, and walk the roof with them during the inspection. Ask us before you file, not after.
When is the best time of year to schedule?
Late spring through early fall is easiest, when the dry season lets underlayment and adhesive set properly. Winter fog and rain still allow repairs, and active leaks get priority.
Can you work on apartments and commercial buildings?
Yes. For occupied buildings we contain debris, protect cars and walkways, and keep loud tear-off work inside reasonable hours. Emergency leaks get handled first.
