We know how Portland rain hits. If your green roof is pooling or your terrace planters are leaking into the floor below, we’re the folks to call. No corporate jargon, just honest work.
We don't do everything—we just do these really well.
When the moss takes over and the water stops moving. We clear those specialized filters and get your roof breathing again.
Most PopularBig architectural planters are beautiful until they leak. We find the breach in the waterproofing without digging up all your plants.
Aggressive Portland moss is a killer for drainage. We don't just blast it; we carefully remove it to protect the membrane underneath.
Most companies see a roof as a project. We see it as a delicate, living system that’s constantly battling the Pacific Northwest drizzle.
We started as two friends with a truck and a specialized interest in why so many 'perfect' green roofs were flooding in the first winter. Ten years later, we’re still those same two guys, just with a few more tools and a lot more moss under our fingernails.
We don’t do mass-market roofing. We do boutique, high-precision cleanup for the buildings that make Portland beautiful. We treat every planter like a sculpture and every drainage membrane like a work of art.

"The best time to fix a leak was yesterday. The second best time is right now—especially in Oregon."
