Leaks & Repair

The Roof Leak Guide: Find It, Stop It, Fix It

If you're reading this because there's water where water shouldn't be, take a breath. Most leaks look worse than they are, almost none of them are emergencies in the next ten minutes, and nearly all of them are fixable without replacing the whole roof.

We're French Roofing, a family roofing company in Damascus. We've chased leaks through every kind of Oregon storm since 2014, and this guide is the conversation we'd have with you on your porch: where leaks come from, how to find the source, what to do right now, and what the fix usually involves.

First: is this urgent?

A roof leak is urgent if water is actively dripping into the living space, spreading across a ceiling, or anywhere near electrical fixtures. Urgent means: contain the water tonight, call a roofer in the morning (or call us now at 971-376-8722 and leave a message; we prioritize active leaks).

It's not urgent if you've found an old stain that isn't growing, a damp spot in the attic after weeks of rain, or exterior wear you spotted from the yard. Those deserve attention soon, not panic now. We sorted the whole list in emergency roof triage: what to do tonight, what can wait.

Where do roof leaks actually come from?

Here's something that surprises most homeowners: leaks rarely come from the middle of a shingle field. Water gets in at the seams and penetrations, the places where the roof is interrupted by something. The usual suspects, roughly in the order we find them:

Why the drip is rarely below the hole

Water is sneaky. It enters at one spot, runs down the underside of the roof deck or along a rafter, and drops onto your ceiling somewhere else entirely. A stain in the hallway can come from an opening ten feet upslope. That's why DIY leak-hunting from inside often points you at the wrong patch of roof.

When we trace a leak, we start at the stain and work upslope, checking every penetration and seam along the water's possible path. Bring a flashlight to the attic during heavy rain and you can sometimes catch the trail shining on the underside of the deck. Follow it up; the entry point is at the top.

What to do tonight (before anyone gets on the roof)

If water is coming in right now:

  • Contain it: bucket under the drip, towels around it, move furniture and electronics out of the way.
  • Poke a small relief hole. If a ceiling is bulging with water, a screwdriver hole in the center of the bulge lets it drain into your bucket instead of collapsing the drywall. Counterintuitive, correct.
  • Take photos and video of everything: the drip, the stain, the date. If this turns into an insurance conversation, you'll be glad you did.
  • Stay off the roof. A wet Oregon roof at night is how homeowners get hurt. Nothing on the roof needs you up there tonight.

Repair, patch, or replace?

Most leaks end in a repair, not a new roof. If your roof is under 15 years old and the problem is isolated (one flashing point, one run of shingles, one pipe boot), a targeted repair is the smart money. If the roof is 20 plus and the leak is one symptom among many (bald shingles, multiple stains, repairs every season), it's worth an honest conversation about replacement instead of paying for the same fix twice.

And patches? A patch has a real job: stopping water fast while the weather or budget catches up. It's a bridge, not a destination. We wrote up when patches work and when they don't.

What a proper leak repair involves

A real repair starts with finding the actual entry point, not just the wet spot. Our crew inspects, photographs, and explains what we found in plain English. Then the fix: replacing the damaged shingles or flashing, sealing the penetration correctly, and checking the decking underneath for moisture damage while we're in there.

You get a written estimate before any work starts. If we find something bigger than expected under the surface, you hear about it right away, with photos and options. That's been the deal since Sean started this company in 2014.

What do leak repairs cost?

Roof repairs in our area range from a few hundred dollars for minor fixes (a pipe boot, a small flashing repair, a few shingles) to several thousand for bigger jobs involving decking or large areas. The honest answer for your roof requires eyes on it, which is why our assessments are free.

We put together a full breakdown of repair costs, including what makes the number go up and down, so you can walk into any contractor conversation knowing the landscape.

After the fix: keeping leaks from coming back

Almost every leak we repair had a warning sign somebody could have caught a season earlier: a cracked boot, a lifted shingle, a mossy valley. Twice-a-year eyes on your roof is the cheapest leak insurance there is. That's what our maintenance program does, and every visit includes an inspection.

Prefer the one-off version? A free roof assessment anytime, no strings. We'd rather catch your next leak while it's still a small fix.
