Frequently Asked Questions

How much does roof repair or replacement cost in San Jose?

Nobody can price a rooftop from a phone call. Most of the number depends on whether we can overlay your existing roof or need a full tear-off down to the deck.

Pitch, the count of roofing squares, and whether the roof deck, plywood, or OSB sheathing has soft spots all move the price. We pull permits and work to San Jose building code, then hand you a free roof estimate with line items.

What happens on install day, and how long does a roof replacement take?

Most single-family homes take one to two days once we start, and winter rain is the real variable here. Dry summers help; storm weeks push schedules.

• We stage a dumpster in the driveway, climb with a ladder and scaffold, and tie a safety harness to a roof anchor on every slope.
• Tear-off comes first, using a roofing shovel and pry bar to strip old shingle, underlayment, and any rotted decking.
• Synthetic underlayment goes down next, with ice-and-water shield along the eaves and valleys, the same detail that guards against an ice dam up in the hills.
• Drip edge, then staggered courses of shingle set with a nail gun off an air compressor and squared up with a roofing square.
• Ridge cap and ridge vent close the top, and flashing goes in at the chimney, step walls, pipe flashing, and boot flashing.
• We sweep for nails, screws, and stray fasteners with a magnet, then haul the debris away.

That underlayment is your waterproofing. The flashing is the weatherproofing at walls and penetrations, and both matter more than shingle color.

Does homeowners insurance cover storm damage on my roof?

Storm damage is often covered. Wear and tear, end-of-life granule loss, and neglected rot usually are not.

We photograph hail damage and wind uplift, note the storm date, and meet your adjuster inspection. If the insurance scope misses decking or flashing, we file a supplemental claim and explain the proof of loss form and reserve release in plain language.

What warning signs mean I should call a roofer?

Walk the yard after a windy night. These are the ones worth a roof inspection:

• Granule loss that leaves bald patches on asphalt shingle and dark grit in the gutter or downspout.
• Curled, blistered, or missing shingles on south-facing slopes that take the worst of the sun.
• Rot and decay in the fascia, soffit, or rake boards where water wicks behind the drip edge.
• Rust or cracked sealant around a pipe boot, vent boot, or chimney flashing.
• Sag in the roofline or a ceiling stain, which can mean a rafter, joist, truss, or ridge beam is wet.
• Loose shingles along the hips, gable ends, and verge edges where wind gets underneath.

Small repairs beat a full roof replacement. Water that seeps into the attic grows mold, so timing matters.

Which roofing materials hold up in San Jose's sun and dry summers?

Dry summers with intense sun and low humidity are hard on anything that oxidizes. Here is what we install most:

• Three-tab shingle for tight budgets, and architectural shingle when you want a heavier, longer-wearing asphalt shingle.
• Wood shake and cedar shake, which breathe well but need steady maintenance and rot faster in shaded yards.
• Slate, clay tile, and concrete tile, heavy systems that often need a purlin, batten, counterbatten, and substrate check first.
• Metal panel, standing-seam panel, and corrugated panel shed water fast and reflect heat; snow guards matter on Mount Hamilton, not in the valley.
• Flat assemblies: TPO, EPDM, PVC membrane, modified bitumen (sometimes torch-applied), and built-up roof over a clean deck.

We also repair older tar, asphalt, and bitumen surfaces, plus felt, roofing felt, and tar paper underlayment on vintage homes where the decking has settled.

Do you handle gutters, skylights, and ventilation too?

Yes. Those details are where most leaks start, and they matter as much as the field of the roof. A licensed & insured roofing contractor should treat them that way.

• Gutter and downspout repair or replacement, with drainage routed away from the foundation.
• Chimney flashing, step flashing, counter-flashing, and apron flashing sealed with mastic or roof cement where metal meets masonry.
• Skylight replacement, plus resealing at a dormer or parapet on a mansard or gambrel roofline.
• Ventilation work such as a ridge vent, soffit vent, or attic fan, plus insulation checks that cut summer heat gain and improve energy efficiency.
• Coating and vapor barrier options on flat sections where ponding water sits near a scupper or coping edge.
• Twice-a-year maintenance that clears debris, checks caulk and adhesive joints, and keeps algae and moss prevention on track.

Deeper repairs get done right: a canopy, awning, or deep overhang all move water somewhere, and we walk through greener roofing choices when a homeowner asks about sustainability.
