Lonnie Currier called us to have us bid a greenroof restoration. What sets this one apart is the original install dates back to the 1970’s! Lonnie’s dad was a real do-it-yourselfer. He used sand as a drain layer and native soil from the back yard. He waterproofed it himself with what we call a hot-mop roof; it’s a system that’s not really meant for subsoil applications. And it started leaking in the 1980’s, so they removed the soil and plants. Lonnie is going to see if he can find photos of the original greenroof. I’ll post them here if any turn up.
