Roof cleaning in Sanger, without the pressure washer

A roof that looks old isn’t always a roof that’s worn out. Around Sanger, plenty of concrete tile, clay tile and asphalt shingle roofs are simply carrying years of dust, pollen and organic growth. The dark streaks running down a slope are usually algae. Winter rain and long, gray stretches of tule fog keep shaded and north-facing sections damp for days at a time, and that’s where algae, moss and crusty lichen take hold. Homes under big shade trees or beside an orchard also collect leaves in the valleys, which hold moisture against the roof and feed more growth.

Pressure washing a roof can crack tiles, knock pieces loose and strip the protective granules off shingles, so we don’t do it. Instead, we pre-rinse your plants and apply a cleaning solution at low pressure, covering the stained areas evenly. It’s given time to work into the growth and break it down, then the roof is rinsed gently. Thick lichen sometimes keeps loosening and fading for a few weeks afterward as the weather rinses it away. We keep foot traffic on tile to a minimum and rinse the gutters, walls, windows and landscaping below before we leave.

Late spring and early fall are comfortable times to schedule in Sanger, ahead of the rains or after the worst of the summer heat. A clean roof also makes cracked or slipped tiles easier to see, and we’ll point out any we notice so you can have a roofer take a look. If you’re thinking about adding solar or listing the house, washing the roof first is a smart move. Many homeowners pair it with gutter cleaning and a house wash so the whole exterior looks consistent from the street.
