The Microclimates of the Lower Mainland and Your Cleaning Schedule
People talk about the Lower Mainland as one place, but for exterior cleaning it is really many microclimates, and where your home sits changes how fast it fouls and how often it needs attention. A home under the North Shore mountains and one on the sunny Delta flats live in genuinely different conditions. Here is how local microclimates should shape your cleaning schedule.

One region, many climates
Rainfall and exposure vary enormously across the region. The North Shore and the forested hillsides of Coquitlam, Port Moody and the Fraser Valley slopes are the wettest and shadiest, so they grow moss fastest. Coastal areas like White Rock, Tsawwassen and Richmond deal with salt air and humidity. The river valleys of Pitt Meadows and Maple Ridge sit in persistent damp. Sunnier, more open and drier pockets foul more slowly.
On top of the regional differences, every property has its own microclimate, tree cover, shade, aspect, drainage, that can matter as much as which city it is in.
How it should shape your schedule
The practical upshot is that there is no single right cleaning frequency for the whole region. Homes in the wettest, shadiest, most tree-covered pockets need roof, gutter and house cleaning more often, sometimes two to three times a year for gutters and every couple of years for the roof. Homes in sunnier, drier, more open spots can often stretch the intervals.
Rather than a generic schedule, the right rhythm follows your local conditions and your specific property, how much rain, shade, tree cover and exposure it actually gets.

Reading your own conditions
The simplest guide is to watch your own home. If the roof greens up, the gutters mat quickly, the north walls film over fast and the walkways go slick, you are in a demanding microclimate and should clean more often. If things stay clean longer, you can stretch the intervals. The home itself tells you.
A local company that knows the region's microclimates can recommend a sensible schedule for your specific area and property rather than a one-size number. That local knowledge is part of the value of hiring someone who works these conditions every day.
