Why San Jose homeowners choose us
Not every symptom means the same repair or the same urgency. Pick what you’re seeing and get a straight answer before you ever pick up the phone.
Typically repairable
Grit collecting at your downspouts means the asphalt mat is now exposed to San Jose’s UV load. Isolated areas can be replaced now cheaper than the leak it turns into. If it’s across the whole roof, we’ll be honest about replacement.

The plain-English version
Fixing localized damage cracked, curling, or missing shingles, failed flashing, or an isolated leak without tearing off the whole roof.
On a typical San Jose repair, our crew pulls the damaged shingles, checks the underlayment and deck underneath for rot, renews any failed flashing, and weaves in new color-matched shingles so the patch is watertight and close to invisible from the street. That’s different from a full re-roof, where the entire shingle field, underlayment, and often the flashing get replaced at once, and a big part of our job is telling you honestly which one you actually need.
Know before it leaks
Staining near chimneys, skylights, and valleys is almost always a flashing failure and still needs a shingle repair to access and reseal.
A roof 15–20 years old? Isolated damage at this age is normal wear old enough to show problems, young enough that a targeted repair still makes financial sense.
What we actually find up there
01
Heavy loss exposes the fiberglass mat and shortens shingle life fast. Isolated areas get replaced; widespread loss points toward replacement.
02
We replace affected shingles and check attic ventilation poor airflow is often the root cause, not just the symptom.
03
Winter gusts break the factory seal. We reseal or replace and install matching starter strip and field shingles where they're missing.
04
Most "shingle leaks" are actually failed flashing. We renew flashing at every penetration caulk-only fixes fail again within a season.
05
Improper nailing lets shingles lift and buckle. We re-secure or replace with the correct fastener pattern for the manufacturer's spec.
06
The ridge takes the most wind and foot traffic. We replace with cap shingles rated for your warranty never mismatched cut-up 3-tab.
07
Rubber collars dry out and crack after 8–10 years in San Jose sun one of the most common, most overlooked sources of a slow attic leak.
08
Older skylight kits deteriorate before the shingles do. We renew the curb flashing and re-integrate it with the surrounding courses.
Straight answers, no upsell
Usually the smarter call
We inspect the roof’s age, condition, and structure before recommending either one. If a repair would run close to half the cost of a new roof, we’ll tell you.
How a new roof goes in
1
We get on the roof and find the true source of the leak checking the deck and ventilation, not just the visible shingles.
2
A clear scope of work and price before anything starts. No surprise add-ons mid-job.
3
Damaged shingles removed, deck checked for rot, ice-and-water shield and flashing renewed, matched shingles woven back in.

Answered honestly
The questions Sunnyvale homeowners ask us most, answered straight.
Most leaks trace back to failed flashing at chimneys, valleys, and wall intersections not the shingles themselves. Cracked vent boots, wind-lifted shingles, and skylight flashing are the next most common causes we find.
Most single-area repairs are done in a few hours to one day. Larger repairs involving multiple leak points or deck replacement may take longer we’ll give you a time estimate with your quote.
Sometimes, wind and storm damage is often covered, while normal wear from age or UV typically isn’t. We provide photo documentation and a written estimate you can submit with a claim.
Yes. Active leaks get priority scheduling. Call 888-336-2115 and we’ll get someone out to stop the water intrusion and assess the damage.
