Flat Roof Repair

What This Service Involves

Flat and low-slope roofs on Washington additions, garages, and mid-century homes struggle when our winter rain has nowhere to run. Ponding water, split seams, and failed drains let moisture sit until it finds a path into the structure below. We identify whether the trouble is a membrane seam, a flashing detail, or a drainage problem, then repair the actual cause rather than flooding the area with coating. Proper slope correction and seam work restore a low-slope roof that can handle the volume our climate throws at it.

Benefits

Resolves ponding that our heavy rains leave behind; Repairs the true source at seams, flashings, or drains; Restores positive drainage on low-slope surfaces; Prevents slow deck rot from standing moisture; Works across membrane, built-up, and coated systems

Our Process

1) Survey the roof for ponding, seam splits, and drain issues; 2) Determine whether membrane, flashing, or slope is failing; 3) Repair seams and flashings or add tapered drainage as needed; 4) Flood-test or water-test to confirm the leak is resolved

What Affects the Cost

Type of low-slope system already in place; Severity of ponding and any slope correction required; Condition of drains, scuppers, and interior drainage; Square footage of the affected membrane area; Accessibility and rooftop equipment in the work zone

Best Time of Year

Dry summer stretches give membranes and adhesives the best cure, but we respond to active flat roof leaks year-round.
