Roof Cleaning Fresno, CA

Roof Cleaning Fresno, CA Residents Trust

Fresno is a two-roof city, and the difference shows from the street. Head north toward Woodward Park, Bullard and the Clovis line and you are looking at clay and concrete tile on newer builds. Drop back into Old Fig Garden, the Tower District, Sunnyside and the older southeast neighborhoods and it is mostly asphalt shingle under a mature tree canopy. Both surfaces grow the same black algae, they just fail in different ways, and that is why we quote a roof after we have looked at it rather than off a price list.

What makes Fresno roofs streak faster than most of California is the winter. Tule fog settles onto the valley floor for days on end between December and February, and a roof under that fog never fully dries. Gloeocapsa magma, the airborne algae behind those black streaks, gets exactly the standing moisture it needs, and it spreads downslope from the ridge. North-facing slopes and anything shaded by the big ash, sycamore and liquidambar trees that line the older Fresno streets stay damp the longest and always look the worst. Then summer flips the switch: weeks of triple-digit heat bake the growth, the ag and road dust, and the residue from the surrounding farmland into a hard crust that a garden hose will never touch.

Left alone, that growth stops being a looks problem. Lichen anchors into the face of concrete tile and into the granule layer of asphalt shingle, so when it finally lets go it takes roof material with it. Moss holds water against the surface and pushes it under the courses. Valley Wash Pros is family owned, licensed and insured, and based right here in northwest Fresno, and we handle every roof the same way: low pressure, the right cleaning solution, and the whole roof, not just the slope the neighbors can see.
