Open seams, punctures, and ponding on white membrane
Western Washington rain pools on low-slope decks and finds the weakest lap, curb, or drain. These are the membrane problems we see most often across Greater Seattle—before a small weld failure becomes a wet ceiling after the next system.
1
Active leaks under a flat section
Water entering below a low-slope deck, wet ceiling tiles, or stains after heavy rain. We trace failures at seams, penetrations, and drains—not only the visible drip. If water is pouring in now, call (425) 758-9982 for after-hours stabilization.
2
Lifted laps, HVAC punctures, or chronic ponding
Separated field seams, foot-traffic punctures around rooftop units, shrinkage at curbs, or standing water that accelerates wear. We assess whether a targeted heat-weld or a membrane section replacement is the better value.
3
Written membrane scope managers can forward
Scope lists seam work, patch materials, drain corrections, and timeline before you approve. Property managers get photos and line items for tenant or board review.
Heat-weld and drain scopes we quote
Flat and low-slope membrane work we quote across King, Snohomish, and Pierce Counties—from lap restoration through partial field replacement.

When a seam patch still beats a new field
We repair when laps, punctures, or isolated sections can be heat-welded or patched without replacing the entire field. When shrinkage, widespread seam failure, or saturated insulation requires a new membrane, we explain options with photos—not pressure to sign the same day. Broader flat-building scopes beyond a single membrane system belong on commercial roof repair.
On qualifying membrane work we offer a 5-year labor warranty and a 30-year material warranty on eligible products. Terms are described on your written estimate before you approve.
