Shingle Roof
Roof leak repair that starts by finding the actual source, not the nearest stain
Water travels before it shows up as a ceiling stain. We trace leaks along the roof deck and flashing to find where water is actually entering, then repair that — not just the drywall underneath.

Why leak location and stain location are often different spots
Water entering at a flashing gap or a cracked shingle can travel several feet along the decking or rafters before dripping through the ceiling. In a region with freeze-thaw cycling, that path can shift seasonally as ice forms and melts. A repair aimed only at the visible stain often misses the entry point entirely.
Ice damming causes leaks in places you wouldn't expect
Backed-up meltwater from an ice dam can push under shingles well above the eave line, showing up as a stain on an interior wall far from where you'd assume the roof failed.
Flashing failures are the most common real cause
Chimney, vent stack, and valley flashing account for a large share of the leaks we trace — far more often than a simple missing shingle.
A patch without tracing the source is a temporary fix
Sealing the visible gap without finding the true entry point often means the same leak returns in a different spot on the ceiling next season.
Attic access speeds up accurate tracing
Where we can get into the attic, we can often see the water trail directly on the underside of the decking, which tells us exactly where to repair on top.
A quick caulk-and-patch quote is guessing, not diagnosing
We've seen leaks 'fixed' three times by different contractors because each one sealed the visible symptom instead of tracing the source. That's an expensive way to solve nothing — the homeowner pays for a patch each time and the leak just reappears with the next thaw.
We trace first, then repair the actual entry point
Our leak repair quotes are based on tracing the water path — through the attic where accessible, along flashing and valleys, and around penetrations — before we quote the fix. That means the repair addresses the cause, and we can tell you honestly if the real fix is bigger than a patch.

Roof leak repair questions
The stain is on my ceiling but not near an exterior wall — how can that be a roof leak?
Water travels along the decking and rafters before it shows up inside, especially with ice damming. The stain location often doesn't match the entry point directly above it.
Can a leak be fixed without going on the roof in winter?
Sometimes, if the source is traceable from inside or the weather allows safe access. For active winter leaks we'll assess what's safely possible and explain the plan.
Will you tell me if it's actually a bigger problem than a leak repair?
Yes — if tracing the leak reveals decking rot or a ventilation problem driving repeated ice damming, we'll explain that rather than just patching the surface symptom.
How fast can you respond to an active leak?
We prioritize active leak calls and aim to get out quickly — email us with the details and we'll confirm timing.
Do you repair leaks around skylights and chimneys?
Yes, flashing around penetrations like skylights and chimneys is one of the most common leak sources we trace and repair.
