Roof Washing in Victoria, BC

It gets soft washed, never pressure washed. The whole point of the service is a cleaning solution doing the work at low pressure, because anything strong enough to blast algae off shingle is strong enough to take the granules with it.

When discussing a Victoria wash, explain the appearance you hope to improve: streaks along several rows, patches around a chimney or staining on an extension. Also flag leaks, cracked shingles or displaced flashing. These require a roofer’s attention independently of cosmetic work. Removing marks cannot restore missing material, mend flashing or prove that a roof is watertight.

There is no fixed clean-roof lifespan tied to the month you book. Algae discoloration may return after cleaning. Ask about suitable scheduling for the actual roof and weather, rather than expecting a November wash to last two weeks or a summer wash to stay clear for a set number of months.

The first decision is whether the roof needs washing or moss removal. Flat black or grey film that follows the shingle courses is a washing problem. Growth with height that can be lifted or brushed is moss, and washing over it skips the part that matters: removing the growth and treating what is rooted under the edge.

Useful photographs show both the marked area and its surroundings. Label an existing picture as the front, rear, garage or extension so the intended cleaning area is clear. There is no need to collect a sample of the stain or access the shingles yourself. If you cannot identify the mark safely, describe it without guessing.

A roof can have both conditions at once. In that case the sequence matters: deal with the moss first, clear what it drops into the gutters, and then decide whether the remaining staining justifies a wash. Selling every dark roof the same treatment is simpler for the contractor, but it is not a useful diagnosis for the homeowner.
