What Sacramento Homeowners Need to Know (2025 Cost Breakdown)
You're standing in your driveway in El Dorado Hills, looking up at your tile roof covered in black streaks and moss. Your neighbor just paid $950 for professional roof cleaning, but you're thinking:
"How hard can it be? I'll just rent a pressure washer and do it myself this weekend."
I get it. A thousand dollars feels like a lot of money.
But here's what I've learned after cleaning 200+ tile roofs across Sacramento County and cleaning up after dozens of DIY disasters:
DIY tile roof cleaning usually costs MORE than hiring a professional when you factor in equipment, time, mistakes, and risk.
Let me break down the real numbers so you can make an informed decision.
