Santa Clara, CA · Roof Repair
Roof repair fixes leaks, missing or damaged shingles, flashing, vents and the decking under them before water damages the attic and ceilings.

The work
We find where the water actually gets in, which is often not right above the stain. Then we replace damaged shingles, reseal or replace flashing around chimneys, vents and skylights, and replace soft decking.
Because A1 also works on chimneys, we fix the flashing and the chimney together when that is where the leak starts.
See the full roof repair page for every detail of the work.
Why it matters here
Northern California has mild, wet winters and long, dry summers. The ground moves, the sun is strong, and wildfire season brings embers.
Strong sun dries out composition shingles and underlayment, and clay tile slips or cracks where people walk on it. Most leaks show up with the first heavy rain of the season.
