Roof leak repair
Roof leak repair means tracing water back to where it actually enters, usually flashing, a vent boot, a damaged shingle or a valley, and sealing or replacing that part. The stain on the ceiling is rarely directly under the hole.

Water travels along decking, rafters and the top of insulation before it drips, so a leak over the living room may start near a chimney or a pipe vent several feet away. A roofer checks the attic for wet decking and stains, then inspects the matching area outside.
The most common sources are cracked rubber boots around plumbing vents, loose or rusted flashing at chimneys and walls, lifted or missing shingles after wind, and worn valleys. If the ceiling is already wet, see storm damage repair or emergency tarping to stop more water first.

Process
What the crew does
- 1
Trace the leak
The roofer checks the attic and the roof above it, often after or during rain, to find where water enters.
- 2
Check the decking
Soft or stained decking around the source is probed; rotted sections are cut out and replaced.
- 3
Repair the source
Flashing is resealed or replaced, vent boots swapped, and damaged shingles replaced and sealed.
- 4
Confirm it's dry
The area is rechecked after the next rain, and interior drying is arranged if the ceiling got wet.
Cost
What affects the price
Every job is scoped on site. These are the factors that move the number.
- Where the leak is (chimney, valley, vent, skylight or open field)
- Roof pitch, height and access
- Whether decking under the leak has rotted
- Matching existing shingles or other materials
- Interior drywall or insulation damage, often handled separately
Before the crew arrives
What you can do, and when to stop
Safe to do
- Put a bucket under the drip and move belongings away
- Turn off the circuit if water is near a light fixture
- Photograph the stain and any visible roof damage from the ground
- Look in the attic with a flashlight for the wettest spot
Stop and call if
- The ceiling is sagging or bulging with water
- The roof is wet, icy or steep; don't climb on it
- Water is near the electrical panel
- The leak keeps spreading after the rain stops
FAQ
Roof Leak Repair questions
Can a roof leak be fixed in the rain?
A roofer can usually tarp or temporarily seal a leak in the rain, but permanent repairs need a dry roof. Tarping first prevents more interior damage.
Why is the leak not directly under the stain?
Water follows the decking, rafters and insulation downhill before it drips, so the entry point is often a few feet up-slope from the stain.
Is a roof leak covered by insurance?
Leaks caused by sudden damage, like a windstorm, are commonly covered. Leaks from worn materials or poor maintenance usually aren't. Check your policy.
