Roof Cleaning in Lodi, CA
Grime Getterz cleans Lodi roofs with soft washing only: low pressure and a sodium-hypochlorite-based mix that kills the algae, moss, and lichen at the root. We never put high pressure on a roof, because it strips shingle granules, cracks tile, and voids manufacturer warranties.
Why Lodi roofs streak and grow moss
The black streaks running down comp shingle roofs across Lodi are Gloeocapsa magma. It's an algae that feeds on the limestone filler in the shingles themselves. Winter Tule fog off the Mokelumne River gives it months of steady moisture, and north-facing planes shaded by Lodi's mature trees never dry out, which is why moss takes hold there. Left alone, the growth holds moisture against the roof and eats away at shingle life.
Soft wash: the only correct method
High pressure on a shingle roof blasts off the protective granules and shortens its life; on the tile roofs common in east Lodi's newer tracts, it cracks tiles and drives water under them. Soft washing works differently: we apply the detergent at low pressure, let it kill the growth, and rinse gently. The streaks disappear and the organisms are dead, not just knocked back, so the roof stays clean far longer.
What to expect on wash day
We protect landscaping, control runoff, and rinse everything down after. On tile roofs we work from ladders and ridge lines rather than walking the field of the roof, because foot traffic cracks tile. Most Lodi roofs are done in half a day, and the remaining treated growth continues to weather off over the following weeks.
Questions We Actually Get
Are the black streaks on my roof just dirt?
No. They're a living algae called Gloeocapsa magma that feeds on your shingles' limestone filler. It has to be killed with detergent, not blasted with pressure, or it comes right back.
Will you walk on my tile roof?
As little as possible. Tile cracks under foot traffic, so we work from ladders, ridge lines, and extended equipment. It's part of why soft washing is the right method for tile.
How long does a roof cleaning last in Lodi?
Typically several years. Because the soft wash kills growth at the root, regrowth is slow, although homes under heavy tree shade or in low fog-collecting spots near the river may see it return sooner.
Does roof cleaning help before selling a house?
Significantly. A streaked roof reads as an old roof to buyers and inspectors. A soft wash makes an aging-but-sound roof look exactly like what it is: sound.
