EPDM Roof Repair

What This Service Involves

EPDM rubber membranes hold up well on Northwest flat roofs, but the adhesive seams and lap joints are where age and weather usually let go. Shrinkage over years can pull the membrane taut at corners and flashings, opening gaps that our winter rain exploits. We clean and prime the rubber, then apply cover tape or splice patches engineered for EPDM so the repair bonds instead of lifting. Addressing seams, pipe boots, and terminations restores a rubber roof that keeps performing without a full tear-off.

Benefits

Rebonds seams with EPDM-specific splice materials; Corrects shrinkage stress at corners and terminations; Reseals pipe boots and flashing details prone to failure; Avoids premature tear-off of a sound rubber field; Handles our wet climate with properly primed bonds

Our Process

1) Inspect seams, laps, boots, and terminations for failures; 2) Clean and prime the EPDM at each repair location; 3) Apply cover tape or splice patches and roll for full bond; 4) Reseal terminations and water-test the finished repair

What Affects the Cost

Age and shrinkage level of the existing membrane; Linear footage of seams requiring re-splicing; Condition of flashings, boots, and edge terminations; Whether ballast must be moved to reach the membrane; Overall roof size and complexity of penetrations

Best Time of Year

Dry, moderate weather gives primers and adhesives the best bond, favoring the summer months for planned EPDM repairs.
