How does El Cajon's climate affect this service?
El Cajon is one of the hottest residential zones in San Diego County. 100-115°F summers, hard-water sprinkler overspray on aging tract stock, I-8 corridor traffic film, and post-fire ash from East County wildfire events drive quarterly cleaning as the working baseline. Arrays here lose production fast without consistent cadence.. East County residential cleanings often catch hard water etching from sprinkler overspray that homeowners didn't realize was happening.
Do you walk on my roof?
Almost never. The standard process uses a ground-based water-fed pole that reaches 24 to 45 feet. The pro only accesses the roof when the geometry of the array makes it physically necessary, and the pro uses roof-safe footwear and harness.
What if my panels are on a steep tile roof?
Tile roofs are exactly why the pole method is used: no walking on tile means no cracked tiles and no slips. If the array is so steep the back row can't be reached from the ground, a pro may use a small cherry picker for that portion.
