Roof Drain Maintenance

What This Service Involves

Clogged roof drains cause ponding that overloads roof structures and drives leaks into public buildings. We clear drains, strainers, and internal downspout lines, then verify free flow from roof to storm system. Debris common to Western Washington sites, from conifer needles to moss, is removed and hauled off. Regular service protects the roof membrane and the building assets beneath it through the region's heavy wet season.
