roof repair is a targeted fix, not a full tear-off. We open only the failed section, replace the damaged rows, and hand-seal the seam with fresh sealant or roof cement.

Failed pipe boots, vent boots, and step flashing cause most of the leaks we find. So does counterflashing behind a chimney, and caulk that dried out on a valley or ridge cap two summers ago.

Where a roof meets a wall, a dormer, or a skylight, the metal does the waterproofing and the shingle does not. Get that detail wrong and water wicks sideways into the sheathing.

If the shingle field is sound, we mend it. If water has already reached the decking, we cut out rotted plywood or OSB and install new sheathing before anything goes back down.

Your house decides the details. Mid-century ranch homes from the 1950s and 1960s often carry three-tab shingle over roofing felt, while Spanish Colonial Revival roofs hide flashing behind stucco.

Contemporary suburban homes built since 2000 usually have architectural shingle over synthetic underlayment. Replacements use a matching profile from GAF, Owens Corning, or CertainTeed so the patch blends into the roofline.

Dry summers and intense sun bake the asphalt and drive granule loss. Winter rain storms test every flashing joint at once. Low humidity and shade let algae and moss cling to a north slope.

What's Included

A roof inspection with photo documentation of every problem area, so you see the flashing failure or granule loss before you approve anything.

Matching shingles for three-tab, architectural shingle, wood shake, or cedar shake roofs, plus metal panel, standing-seam panel, slate, and tile patch work.

Targeted tear-off of the failed field course instead of the whole roof, so you keep the sound shingles you already paid for.

New underlayment and self-adhered ice-and-water shield beneath any patch, which stops water from wicking back into the decking.

Replacement pipe boots, vent boots, and step flashing wherever a roof plane meets a wall, dormer, or skylight.

Rebuilt chimney flashing and counterflashing, bedded in roof cement or mastic, since chimney joints leak in nearly every winter storm.

Fresh sealant at the drip edge, ridge cap, valley, and rake, plus a bead of caulk around any exposed fastener.

Low-slope porch and garage sections resealed with modified bitumen, TPO, or EPDM, where ponding water and UV degradation do more damage than sun on a pitched shingle roof.

Our Roof Repair Process

What Happens During a Roof Repair, Step by Step

Step 1: We set a ladder or scaffold, clip in with a safety harness, walk the roof from the ridge down, then check the same areas from inside the attic.
Step 2: You get a written estimate that separates labor, shingle, underlayment, and flashing, and notes any building code items such as ventilation or a vapor barrier.
Step 3: We set a dumpster, stage materials, and protect the landscaping so the crew is not crossing your driveway all afternoon.
Step 4: Damaged shingles come off with a pry bar and roofing shovel. We skip a full overlay or recover unless the decking is already flat, dry, and sound.
Step 5: New self-adhered ice-and-water shield and synthetic underlayment go down before any shingle, never after.
Step 6: Replacement shingles are fastened with ring-shank nails, aligned to the existing starter course, and staggered across the field course so the patch disappears.
Step 7: We reseal the drip edge, ridge cap, valley, and chimney flashing, then run a magnet sweep and haul the old shingle and debris away.

Signs You Need Roof Repair

Signs Your Roof Needs Repair Before the Next Rain

Granule loss shows up as grit in your gutters, and asphalt shingles that shed grit are close to end-of-life wear.
Brown ceiling stains, or a sag in the drywall below the attic, mean water has already seeped past the underlayment.
Moss and algae streaks on a shaded north slope, which low humidity and long dry spells let spread across a shingle field unnoticed.
Curled, cracked, or missing shingles after a winter storm pushed wind under the field course.
Rusted valley metal and grit piling up where two roof planes meet, a classic sign the flashing has started to peel.
Cracked or dried sealant around a pipe boot, vent boot, or skylight frame that you can spot from the ground.
Daylight or damp rafters visible from inside the attic, which usually means decking rot has begun.
Peeling paint on a chimney, or a fascia board that feels soft, both of which point to a slow leak behind the counterflashing.

Roof Repair — Frequently Asked Questions

How much does roof repair cost in San Jose?

Roof repair pricing follows the scope: how many shingles need replacing, how much flashing is involved, and whether the decking is soft. A single pipe boot is a small job; rebuilding chimney flashing takes longer. Parts and labor are listed separately on every estimate.

How long does a roof repair take?

Roof repair usually takes one day for a simple patch, and two to three days when flashing, decking, and shingles stack up. Summer work moves fast because the shingles seal in the heat. Winter jobs wait for a dry window.

Can you repair a roof instead of replacing it?

Roof repair is the right call when the shingle field is sound and the damage sits at the flashing, a valley, or one slope. If a third of the roof shows granule loss or curling, replacement usually costs less over the next decade.

Do you help with insurance claims after storm damage?

Roof repair after a storm often starts with an insurance claim, and we help document it with photos and a written scope of work. We will meet the adjuster on the roof and point out flashing, decking, and shingle damage that is easy to miss from the ground.

Does the local climate change how long a roof lasts?

Roof repair schedules shift with the weather here. Dry summers and intense sun bake the asphalt in your shingles, so granule loss shows up years before a leak does. Winter rain storms then test every flashing detail at once.

What should I check after a heavy rain?

Roof repair after heavy rain usually starts at the valleys, the ridge cap, and anything the wind could lift. Check the yard for shingles, the gutters for grit, and the attic sheathing for damp spots.

“We had a stain spreading across the ceiling in Willow Glen and figured the whole roof was gone. They found one failed pipe boot and a cracked vent boot, patched both, and showed me photos of the dry decking underneath. Free estimate, no upsell.” — Maria R., Willow Glen

“After a winter storm, water was dripping into our kitchen in Almaden Valley. They replaced the step flashing at the sidewall, resealed the valley, and cleared debris out of the gutters and downspouts. One day, start to finish.” — Dan K., Almaden Valley

“Our rental near Downtown San Jose had a chimney leak nobody could trace. They repacked the counterflashing and ran new chimney flashing, then walked me through the attic to show the dry sheathing. Honest about what did not need replacing.” — Priya S., Downtown San Jose
