Concrete and clay tile roofs are one of the most popular roofing choices in Florida — and for good reason. They're durable, energy-efficient, and well-suited to the state's climate. But tile roofs are not maintenance-free. In Florida's humid, warm environment, they develop algae, mold, moss, and lichen growth that degrades the tile surface, clogs the valleys between tiles, and creates a visually striking — and damaging — discoloration that spreads across the roof over time.

If you have a tile roof anywhere in Central or Northeast Florida — Volusia, Flagler, St. Johns, or Orange County — this guide covers everything you need to know about professional tile roof cleaning.

How Tile Roofs Get Dirty in Florida

Tile roofs in Florida face a specific combination of biological threats:

Algae (Gloeocapsa magma) — the same cyanobacteria that causes black streaking on asphalt shingles also colonizes tile roofs. On tile, it appears as dark gray or black discoloration that spreads from the ridge down toward the eaves.

Moss — thick green or brown moss growth is common on tile roofs in shaded areas, particularly in neighborhoods with mature tree canopy. Moss holds moisture against the tile surface and can lift tile edges as it grows, creating leak pathways.

Lichen — a combination of algae and fungus, lichen forms crusty gray or green patches that bond tightly to the tile surface. It's the most difficult biological growth to remove from tile and requires professional treatment.

Mold and mildew — dark patches and streaking, particularly on north-facing roof sections and in valleys where moisture accumulates.

Why You Should Never Pressure Wash Tile Roofs

High-pressure washing is one of the most common — and damaging — mistakes homeowners make with tile roofs. The problems with pressure washing tile include:

• Cracked and broken tiles — walking on a tile roof without proper training and equipment cracks tiles; high-pressure water can also crack or chip tile surfaces
• Damaged underlayment — water forced under tiles at high pressure saturates the underlayment, leading to leaks and deck damage
• Displaced ridge caps — high-pressure water can dislodge the mortar holding ridge cap tiles in place
• Stripped tile coating — many concrete tiles have a factory-applied coating that provides color and UV protection; pressure washing strips this coating, accelerating fading and surface degradation

The correct method for cleaning tile roofs in Florida is soft washing — low-pressure application of professional cleaning solutions that kill biological growth at the root without any of the mechanical damage risks of pressure washing.

The Soft Wash Process for Florida Tile Roofs

A professional soft wash tile roof cleaning follows a specific process:

1. Pre-inspection — assessing tile condition, identifying cracked or displaced tiles, checking ridge cap mortar, and evaluating the degree of biological growth
2. Dry debris removal — clearing leaves, pine needles, and debris from valleys and gutters before applying solution
3. Solution application — low-pressure application of a professional-grade sodium hypochlorite solution that kills algae, moss, lichen, and mold
4. Dwell time — allowing the solution to penetrate and kill biological growth; heavier growth requires longer dwell time
5. Gentle rinse — low-pressure rinse that removes dead growth and cleaning solution residue
6. Post-cleaning inspection — confirming complete coverage and identifying any tiles that need repair

How Long Do Results Last on Florida Tile Roofs?

A professionally soft-washed tile roof in Florida typically stays clean for 2–4 years. Coastal properties in Volusia and Flagler counties — where salt air and higher humidity accelerate biological growth — may see results closer to 2 years. Inland properties in Orange and St. Johns counties often see results lasting 3–4 years.

Applying a post-cleaning algae inhibitor treatment can extend results by an additional 1–2 years by creating a surface environment that's hostile to new algae growth.
