Enviroscapes Greenroofs

Enviroscapes Northwest specializes in greenroof construction for residential, commercial, institutional, or other types of properties. We have experience with all types of greenroof systems including field planted, pre-grown vegetated mats, and modular systems, so whichever the appropriate greenroof solution for a project may be, Enviroscapes Northwest is able to install and maintain it competently and professionally.

Due to their environmental benefits, a variety of public incentive programs exist to promote greenroof installation. Enviroscapes Northwest will identify which subsidies your project is a candidate for, and at no additional charge will lead the effort to secure whatever funding is available for our clients.

Key Greenroof Benefits

Extends roof life - A greenroof provides an average of 4" to 6" of protective cover to rooftop waterproofing, shielding it from UV radiation and exposure to the elements. Protecting the waterproof membrane with a greenroof extends the life of the roof at least twice that of a conventional roof, saving replacement costs and reducing building cost of ownership.

Stormwater management and watershed health - A greenroof captures and evaporates from 10% to 100% of the precipitation that falls on it. Stormwater shed from a greenroof is greatly reduced in volume and speed, as well as cooled and improved in chemical quality. These combined benefits minimize the contribution to the public stormwater infrastructure, and protect and improve downstream river and watershed health.
