Green Roof Installation

What This Service Involves

A green roof layers waterproofing, root barrier, drainage, and growing medium beneath hardy vegetation, and in our rain-heavy region its stormwater retention is a genuine advantage for managing runoff. We start with a robust, root-resistant membrane and leak-test it thoroughly before a single plant goes down, because access is difficult once the assembly is complete. Plant selection favors sedums and other species that thrive in the Puget Sound climate, tolerating both soggy winters and our drier late summers. The finished roof cools the building, extends membrane life by shielding it from UV, and softens the urban landscape while quietly handling the water our skies deliver.

Benefits

Vegetated layers retain and slow stormwater runoff; Living surface insulates and cools the building below; Plant cover shields the membrane from UV to extend its life; Root-resistant waterproofing leak-tested before planting; Habitat and greenery enhance dense urban settings

Our Process

1) Verify structural capacity for the saturated system weight; 2) Install and flood-test a root-resistant waterproofing membrane; 3) Layer drainage, filter fabric, and engineered growing medium; 4) Plant climate-appropriate vegetation and set up irrigation as needed

What Affects the Cost

Structural capacity to carry the saturated roof weight; Depth of growing medium and the plant palette chosen; Waterproofing and root-barrier system specified; Drainage, irrigation, and edging components required; Roof access and how materials are hoisted into place

Best Time of Year

Late spring to early summer lets new plantings establish roots during the warm, drier stretch before winter rains arrive.
