Seattle’s weather makes it worse. Months of steady rain keep the roof wet, moss and fir needles hold water against the shingles and in the valleys, and clogged gutters back water up under the roof edge. A small gap gets weeks of water to work with.
So our roof leak repair begins up top. We follow the water back to its entry point, photograph it and repair that spot properly.
Rubber boots harden and split, and rain runs straight down the pipe.
Flashing
Lifted or rusted metal around chimneys, walls, skylights and valleys.
Moss and debris
Moss and needles that wick water under shingle edges and clog valleys.
Wind damage
Creased or lifted shingles that let sideways rain underneath.
Gutters and eaves
Clogged gutters overflowing behind the fascia and into the roof edge.
Flat roofs
Open seams, blisters, blocked drains and water sitting on low-slope sections.

Roof types
Cedar shake and flat roof leaks
Cedar shake roofs are common around Seattle, and they leak in their own way. Shakes split, cup and wear thin with age, moss fills the gaps between them, and water finds its way to the layer underneath.
Flat and low-slope roofs leak at seams, around drains and anywhere water sits after days of rain. We check the whole surface, not just the spot above the stain.
FAQs
Roof leak repair questions
Straight answers to the questions we hear most. Don’t see yours? Give us a call.
Drizzle runs off. Driving rain gets forced under lifted shingles, loose flashing and split boots, and overflowing gutters push water in at the eaves. We check those first.
Can moss cause a roof leak?
Yes. It holds rain on the roof and lifts shingle edges until water runs under them. We clear it, repair what it damaged and can talk about slowing the regrowth.
Can you repair a leak without replacing the roof?
Usually. Most leaks come from one or two spots. If the whole roof is worn out, the photos will show it and we’ll say so.
