Climate notes for Washington
Moss and algae thrive in the long wet season, especially on shaded roofs. The driest weather west of the Cascades is usually July to September, which is the best time for staining and sealing because most products need several dry days. Moss treatments are often done in spring or early fall.
What makes surfaces get dirty faster
- Shade and moisture: algae, mold and mildew need surfaces that stay damp. North walls, shaded roofs and decks under trees grow back first.
- Trees: leaves, pollen, sap and seed pods stain surfaces and fill gutters.
- Salt air: near the coast, salt film dulls windows, metal and paint and holds moisture.
- Traffic and dust: busy or unpaved roads coat siding, windows and solar panels.
- Sprinklers: they keep walls wet and leave mineral and rust spots.
These are general guidelines. If you see growth or streaks coming back sooner, clean sooner; waiting lets stains set in and organic growth damage the surface.
