We built a Northwest Modern home that consists almost entirely of four elements; stone, glass, copper, and bamboo. Another unique feature is a vegetated rooftop cover installed over a waterproof membrane, known as a living roof (or green roof). This roof can retain sixty to one hundred percent of incoming rainfall which helps protect the delicate bluff top setting where the house is situated.
The green roof was installed by Xero Flor. Xero Flor is the same company that installed a ten acre green roof at the Ford Motor Company Dearborn Truck Plant which is recognized by the Guinness Book of World Records as the largest living roof in the world. Xero Flor green roofs consist of sedum, moss, and native perennial vegetation on a flexible textile carrier. Xero Flor pre-vegitatived mats are grown at regional farms across the country to ensure regionally adapted plant communities. The mats are rolled up and installed just like sod.
Xero Flor featured our Northwest Modern home on their website to showcase how a vegetated rooftop can be used on varying roof slopes and unique shapes.
We recently installed a Xero Flor living roof on one of the floating homes we are building in the Port Townsend Shipyard.
You can see many examples of green roofs at the National Geographic’s Green Roof Photo Gallery.
