Moss removal on a roof
Roof moss
Shaded roofs stay damp for months, and moss lifts shingles and holds water against them.
Our tip: Treat in early fall each year, before it gets thick.

Your Vancouver home exterior guide
Long, damp winters and big evergreens are why we love it here, and why moss and algae grow on everything. Here's what we see most, and how to stay ahead of it.
What we see most
Common problems on Vancouver homes
Soft-washing siding
Green siding
North-facing walls and anything near trees or sprinklers grow green algae and mildew.
Our tip: A yearly soft wash stops it before it stains.
A freshly cleaned home
Black roof streaks
Dark streaks running down shingles are usually algae, not dirt or age.
Our tip: A gentle treatment removes them. No scrubbing needed.
Driveway being cleaned
Slick walks & decks
Moss and algae turn concrete steps and wood decks into a fall risk all winter.
Our tip: Clean and post-treat in fall, before the rains set in.

Neighborhoods
From Esther Short to Minnehaha
We know these streets: the craftsman homes in Hough and Arnada, the shady lots in Felida, the newer neighborhoods out by Fisher's Landing. Every home gets a different amount of sun, shade and moss, and we clean for that.
Good to know in Vancouver
Only rain belongs in storm drains. They flow to local streams and the Columbia River. We keep wash water with cleaners and debris out of them, directing it to landscaping or collecting it.
