They sound like the same job. They're not — different growth, different method, different stakes. Plenty of homeowners around Orlando and Clermont have paid a "wash guy" who put a pressure wand on the roof. That roof lost years of life that day. Here's what each service actually is.
Two different services
House washing is your home's walls — siding, stucco, soffits — cleaned with a low-pressure soft wash that removes the green algae, mildew and grime Florida humidity grows.
Roof cleaning treats the roof surface itself, almost always for black streaking, with an even gentler soft wash. It's the one service where pressure isn't just wrong — it's destructive.
Side by side
| House washing | Roof cleaning | |
|---|---|---|
| Targets | Green algae, mildew and grime on walls and soffits | Black streaks (Gloeocapsa magma algae), lichen and moss |
| Method | Soft wash — low pressure + solution | Soft wash only, even gentler application |
| Pressure allowed? | Never on siding or stucco | Never, period — pressure strips shingle granules |
| How often in FL | About once a year | Every 1–2 years, sooner under heavy shade |
| Why it matters | Curb appeal and paint life | Shingle life — and how your roof photographs for insurance |
Those black streaks are alive
The dark streaking on Florida roofs is Gloeocapsa magma — an algae that feeds on the limestone filler in shingles and loves our humidity. It spreads, holds moisture against the roof, and degrades what it's eating. We wrote the full story in why Florida roofs turn black. The short version: it's an organism, so it has to be killed, not blasted.
The insurance angle
Anyone dealing with Florida homeowners insurance lately knows roof condition drives everything — inspections, underwriting, renewal. A sound roof buried under heavy algae staining photographs terribly. A soft wash restores its appearance without touching its integrity. What you never want is pressure damage on a roof an inspector is about to photograph.
Do them together
If your roof needs cleaning, pair it with a house wash. The crew and landscaping protection are already in place, and roof rinse water runs down the walls — so roof first, house second leaves everything spotless in one visit. That's the standard combo we run across Orlando, Clermont, Windermere, Dr. Phillips, Horizon West and Winter Garden.
Quick answers
Can you pressure wash a shingle roof? No. Pressure strips the protective granules and shortens roof life. Soft washing is the only safe method — and the industry standard.
How often should I do each? Most Central Florida homes: house wash yearly, roof soft wash every 1–2 years, sooner under oaks or heavy shade.
