Langford's housing boom means plenty of roofs that are under 15 years old and still holding valid shingle warranties. Those newer roofs are not immune to moss: north-facing slopes in Westhills, Bear Mountain, and the Latoria corridor stay shaded long enough for growth to take hold within a few years of construction. We use soft-wash technique on every roof we touch, low pressure and a biodegradable solution that kills spores at the root without scouring the shingle surface underneath.

Low-pressure application of a biodegradable solution. Kills moss and algae at the root instead of blasting spores sideways across the shingle surface.
Pressure washing strips granules and voids most manufacturer warranties. Our process does neither, which matters on newer Langford homes still under coverage.
Some Langford builds used cedar shake. Different solution mix and dwell time for cedar; we do not run the same recipe on every roof regardless of material.
Anything the rinse pushes into the gutters gets bagged and removed before we leave.
Each slope photographed before and after. Notes on anything worth watching, sent that afternoon.
Add a top-ridge zinc strip after the clean for slow ongoing moss control. Slows regrowth on shady slopes.

Heavy lichen, steep pitch, or post-storm debris may add a small surcharge. We confirm everything in writing before we start.

Soft washing, done right, does not. Pressure washing often does. Most manufacturers actually require regular cleaning to keep the warranty active. We work to a low-pressure spec that leaves the granules in place and keeps your coverage intact.
Yes, especially on north-facing slopes or anywhere with tree cover overhead. Moss can establish on a new asphalt shingle within three to five years in this climate. Catching it early is cheaper than removing it once it has lifted the shingle edges and started trapping moisture against the wood beneath.
A typical Langford home takes two to four hours depending on size and how heavy the growth is. Adding a zinc strip extends the visit slightly for the application and dwell period before rinsing.
In Greater Victoria's climate, expect two to four years without a preventive treatment. With a zinc or copper ridge strip, many homes go three to five years before a full re-clean is needed. Shade, tree cover, and roof pitch all push that number one way or the other.
No. Roof work is exterior only. Point us at the access path on quote day and we will send the photo report when we are done.
