Roof Leak Repair Boise
A ceiling stain is almost never directly under the hole. Water enters at a penetration, runs along the underside of the decking or down a rafter, and drops wherever it finds the low point. That can be twenty feet away.
Which is why roof leak repair is mostly a diagnosis job. Patching the visible stain fixes nothing.
Where Boise leaks actually start
In rough order of how often we find them:
Pipe boots. The rubber collar around plumbing vents. Cracks from UV and thermal cycling — Boise’s dryness and 70-degree annual swing are brutal on them. The most common single source we see.
Flashing. Chimneys, skylights, sidewalls, dormers. Often the metal is sound and the sealant behind it has gone brittle.
Valleys. Where two roof planes meet, carrying the most water on the roof. Debris packs in — particularly under the North End and East End tree canopy — and holds moisture against the roof.
Nail pops. Fasteners backing out through thermal cycling, each one a small hole.
Ice dam backup. Winter-specific. Meltwater refreezes at the cold eave and backs up under the shingles. This is a ventilation and eave-protection problem, not a shingle problem.
Wind-lifted shingles. Tabs that lifted in a spring gust and resealed out of position, leaving a channel.
Roof-to-wall transitions. Where a lower roof meets an upper wall — step flashing done badly is a persistent leak.
How we find it
Interior first. Where the stain is, what’s above it, what direction the framing runs.
Attic second. This is where the truth is. Daylight, staining on rafters and decking, wet insulation, and the actual water path. Most leaks are solved in the attic, not on the roof.
Then the roof. With the attic evidence, we know roughly where to look rather than guessing.
Water testing if it’s still not obvious — running water systematically over sections while someone watches from inside. Slow, but it’s the only reliable way on a stubborn leak.
What roof leak repair costs in Boise
Diagnosis is included in the free inspection. You pay for the repair, not for us finding it.
What to do before we arrive
Put something under the drip and move what you can
If the ceiling is bulging, keep people and valuables out from underneath it. Don’t puncture it or stand beneath it — tell us immediately.
If you can do so safely, turn off power to any circuit near the water
Photograph everything while it’s wet — useful if a claim follows
Don’t go on the roof
Will insurance cover a roof leak?
It depends on cause, not on the leak itself. Sudden and accidental — wind, a tree strike, storm damage — is usually covered. Gradual wear or deferred maintenance usually isn’t.
The grey area is large, and how the damage is documented matters. If the leak followed a storm, photograph before anything is covered or repaired, and consider a claim. Our insurance claims page covers ACV vs RCV and what actually determines your payout.
FAQs
01 How quickly should I fix a roof leak?
Quickly. Water reaches insulation and drywall within hours and framing within days. Mould becomes a real risk within about 48 hours in a warm attic.
02 Why is my ceiling stain not under a hole in the roof?
Because water travels along decking and rafters before dropping. This is normal and it’s why diagnosis matters more than patching.
03 Can you fix a leak in the rain?
We can tarp it in the rain. Permanent repairs need a dry deck — sealants and adhesives won’t bond otherwise.
04 How much does it cost to find a leak?
The inspection and diagnosis are free. You’re paying for the repair.
05 My roof is new and it’s leaking. What now?
Usually a workmanship or detail issue rather than a material failure — flashing, a penetration, or a valley. Worth checking your installer’s workmanship warranty first. If they won’t come back, we will.
