Selma roof cleaning without the pressure washer

Look at a few rooftops around Selma and you’ll notice a pattern. North-facing slopes and sections under trees are darker than the rest, often with black streaks running down from the ridge. Those streaks are usually algae, not plain dirt. In winter, tule fog and rain keep shaded parts of the roof damp for days, giving algae, moss and lichen the moisture they need. Through the dry months, dust from surrounding vineyards and orchards settles into the texture of the tiles and dulls the color even more. Over the years, a perfectly sound roof can start to look old and worn out.

The fix isn’t high pressure. Blasting a tile roof can crack or loosen tiles, and on asphalt shingles it strips away the granules that protect them. We soft wash instead. A cleaning solution is applied at low pressure so it can break down algae, moss and lichen, then given time to work before the roof is gently rinsed. Thicker lichen may keep loosening and fading for a few weeks afterward as the weather rinses it away. We pre-rinse your landscaping, rinse the gutters, walls and windows below, and keep foot traffic on the tiles to a minimum.

Selma has plenty of concrete tile roofs on stucco homes, along with older shingle roofs near downtown and on farmhouses outside town. Both respond well to a soft wash. A clean roof also makes it easier to spot cracked or slipped tiles that a roofer may want to look at, and it’s a good step before listing a home or adding solar.
