FAQ: Can I Pressure Wash My Roof?

Short Answer: No — pressure washing can seriously damage your roof and void its warranty.

Why Pressure Washing Your Roof Is a Bad Idea

While it might seem like a quick fix to remove mold, algae, or stains, using high-pressure water can:

  • Strip off protective granules from asphalt shingles

  • Tear or loosen shingles and flashing

  • Force water under the shingles, leading to leaks or wood rot

  • Void manufacturer warranties

According to the Asphalt Roofing Manufacturers Association (ARMA), high-pressure cleaning can degrade the integrity of shingles and compromise long-term roof performance.

The Safer Alternative: Soft Wash Roof Cleaning

Soft washing uses low-pressure water combined with cleaning solutions specifically formulated to remove:

  • Algae

  • Mildew

  • Lichen

  • Moss

  • Dirt and stains

This method is approved by roofing manufacturers and is safe for asphalt shingles, tile, and metal roofing systems.

Should You Clean the Roof Yourself?

We strongly recommend you don’t. Walking on a wet roof is dangerous, and using the wrong technique can do more harm than good. Let licensed roofing professionals or trusted soft-wash contractors handle it.

At Roof Nuts, we’re happy to recommend reliable roof cleaning pros across Florida — from Jacksonville to Miami.

FAQs

How often should I clean my roof in Florida?
Every 2–3 years, or whenever you notice algae streaks or buildup. Florida’s humid climate makes roofs prone to organic growth.

Will algae or mildew damage my shingles?
Yes. Algae can eat away at shingle materials over time and trap moisture, shortening your roof’s lifespan.

Can I use bleach or vinegar instead?
Only with the right dilution and rinsing — and even then, it's risky. Some chemicals can damage roofing components or landscaping if not applied correctly.
