A roof valley is the channel where two roof planes meet, and it carries more water than any other part of your roof. Valley leak repair Aberdeen WA means finding where that channel has failed, whether it's worn flashing, a torn underlayment, or shingles that have pulled apart. We open up the valley, inspect the metal or membrane lining, and rebuild it so water flows to the gutter instead of into your attic.
Aberdeen's wet winters and moss growth push roof valleys hard. If you've noticed ceiling water stains or damp insulation, valley leak fixing in Aberdeen WA is usually the fix. We use a moisture meter and infrared thermal camera to trace the leak back to the valley before we start tearing anything apart. That saves you money and gets the repair done right the first time.
Every valley leak repair we do includes a thorough inspection, a written estimate, and a hose test to confirm the fix. Here's what's covered.
We inspect the entire valley, including underlayment, flashing, and surrounding shingles or tiles. We also check gutters and downpipes for blockages that could cause water to back up.
We use a moisture meter and infrared thermal camera to trace the leak path. This tells us exactly where water is entering, so we don't waste time or materials on guesswork.

If valley flashing is cracked or rusted, we replace it with new metal flashing. We also repair step flashing and counter-flashing around chimneys and walls.
After the repair, we run water through the valley to confirm it's leak-free. Then we clean up all debris and nails. You get a written warranty on the workmanship.
