Roof Cleaning for Nanaimo Homes
Nanaimo climbs from the harbour to the bench under Mount Benson, which means roof slopes here face every direction and get very different amounts of sun. A roof that looks fine from the street can be carrying most of a winter on the side nobody drives past.
Why Nanaimo Is Its Own Problem
Six Months Without Sun on the North Slope
A true north slope here does not dry out from late September to late March — at this latitude the winter sun never swings north of the roofline, so that side of the house goes roughly six months without a direct hour on it. That is why moss on a Nanaimo roof is usually a north-and-west-slope problem while the south face still looks fine. The city adds its own version of the same thing: Mount Benson stands 1,023 metres high nine kilometres due west, so the western side of Nanaimo loses the low afternoon sun behind a mountain rather than to the horizon, and slopes facing that way get fewer drying hours than the same slope would on open ground. None of it changes the rule: asphalt shingle gets soft washed, never pressure washed.

Roof Cleaning Questions
Once a year is enough almost nowhere in Nanaimo, and the reason is the mix of trees rather than the amount of rain. If your lot has fir or cedar on it, needles come down all year and heaviest through August and September, so the gutters are part full before the deciduous drop even starts. Clean once in October and you catch the needles and miss the leaves; clean once in December and the needles sat there all autumn. Twice is the honest answer for a treed lot. Once is genuinely fine for an open lot in the north end with nothing overhanging it.

Nanaimo and Nearby
Nanaimo is the largest service area on this list and the least uniform. A job in the Old City Quarter and a job in Linley Valley are twenty minutes and a hundred and thirty years apart, so quoting here leans harder on the address than it does anywhere else on this list.
