Parapet Wall Repair

What This Service Involves

Parapet walls take a beating from wind-driven Puget Sound rain, and their coping joints and counterflashing rank among the most common leak sources on commercial buildings. Failing coping, cracked masonry, and lifted flashing let water track down inside wall cavities where it goes unnoticed until damage is significant. We rebuild these transitions with proper counterflashing, sealed coping, and membrane terminations that shed water back onto the roof. Correcting the parapet often resolves chronic leaks that repeated interior patching never fixed.

Benefits

Stops hidden water intrusion inside wall cavities; rebuilds coping and counterflashing to shed wind-driven rain; protects masonry from moisture-related cracking; integrates cleanly with the existing roof membrane

Our Process

1) Inspect coping, flashing, and the wall-to-roof junction; 2) Remove failed coping and deteriorated sealant; 3) Install new counterflashing and membrane terminations; 4) Seal and cap the parapet for a watertight finish

What Affects the Cost

Length and height of the parapet run; coping material and condition; extent of masonry or substrate repair; access and staging requirements

Best Time of Year

Dry summer weather is best for sealant curing and masonry work, though targeted repairs can address active leaks any time of year.
