Pressure washing is a powerful cleaning method, but when used on roofs, it can cause more harm than good. Many homeowners assume it’s the best way to remove dirt, moss, and algae, but improper cleaning can lead to costly damage. Before blasting your roof with high-pressure water, here’s what you need to know.

1. High-Pressure Water Can Damage Shingles
Roof shingles, especially asphalt ones, have a protective layer of granules that shield them from sun and weather damage. Pressure washing can:
- Strip away these granules, shortening the roof’s lifespan.
- Loosen or dislodge shingles, leading to leaks.
- Force water under the roofing materials, causing moisture buildup and mold growth.
Instead of pressure washing, a gentler cleaning method like soft washing is recommended to protect your roof. Waterworks Pressure Cleaning specializes in safe, effective roof cleaning.
2. Increases the Risk of Leaks
Roofs are designed to shed water, not withstand it being blasted at high speeds. Using high pressure can:
- Push water under the shingles, leading to interior leaks.
- Soak the underlayment, causing long-term moisture damage.
- Lead to costly repairs from water infiltration.
A low-pressure soft washing technique is a much safer way to clean your roof without causing water damage.
3. Promotes Mold and Algae Growth if Done Incorrectly
While pressure washing may remove visible algae and moss, it doesn’t always eliminate the root problem. If moisture seeps into the roof’s structure, it creates a perfect breeding ground for:
- Mold and mildew, which can spread to your attic and walls.
- Algae that reappears quickly, leaving unsightly black streaks.
- Weakened shingles, making your roof more vulnerable to damage.
A professional soft wash treatment from Waterworks Pressure Cleaning effectively removes algae and prevents regrowth.
4. Voiding Your Roof Warranty
Many roofing manufacturers do not recommend pressure washing and state in their warranties that high-pressure cleaning can void coverage. If your roof gets damaged due to improper washing, your warranty may no longer apply. Always check with a professional before attempting any DIY cleaning.
Hiring trained experts like Waterworks Pressure Cleaning ensures your roof is cleaned safely and in compliance with manufacturer recommendations.
5. The Safe Alternative: Soft Washing
Instead of pressure washing, soft washing is the preferred method for roof cleaning. This process:
- Uses low-pressure water combined with specialized cleaning solutions.
- Kills mold, algae, and moss at the root for long-lasting results.
- Preserves the integrity of your roof while restoring its appearance.
