Frequently Asked Questions

Roof cleaning typically costs about $0.25 per square foot of roof area. For a standard Fort Lauderdale single-family home, that translates to $350-$900 depending on roof size. We provide free estimates with exact pricing after assessing your roof.

No. High-pressure water erodes tile surfaces, strips color, cracks tiles, and can force water under the tile layer. The ONLY safe method for concrete tile roofs is soft washing — low-pressure chemical application that kills organisms without mechanical damage.

Dark streaks are caused by Gloeocapsa magma, a cyanobacterium that feeds on calcium carbonate in concrete tiles. It produces a dark melanin sheath for UV protection, creating visible staining. It requires chemical treatment (soft washing) to eliminate.

Every 18-24 months for most homes. Properties with heavy tree coverage or in shaded areas may benefit from annual cleaning. Regular maintenance prevents heavy buildup and costs less per cleaning.

We pre-wet all plants before treatment and thoroughly rinse after. Landscaping protection is built into our standard process. We've never had a landscaping damage claim.

Most single-family home roofs take 1-3 hours depending on size and accessibility, including chemical application, dwell time, and rinse.

Yes — dramatic improvement immediately. Some residual staining clears over 2-4 weeks as dead material washes away naturally with rainfall.

Absolutely. Biological growth accelerates tile deterioration. Regular cleaning allows concrete tile roofs to reach their full 50+ year design lifespan, potentially saving $15,000-$40,000+ in premature replacement.
