Fungal Shield

Save Your Tiles — Florida's Clear Anti-Fungal Roof Tile Sealer & Anti-Algae Coating

Overview

Fungal Shield (RP1) is RoofProtect's clear anti-fungal roof coating, available exclusively through The Roof Store — the answer to South Florida's most common roof complaint: black streaks, green algae patches, and mold colonies that make a perfectly sound roof look like it needs replacing. These aren't cosmetic issues — they are living biological organisms actively breaking down your roofing substrate.

Fungal Shield starts from a clear elastomeric base, to which additional active ingredients are added to create its biocide formula. It penetrates and bonds to clay tile, concrete tile, metal, and flat roof surfaces, killing existing biological growth while creating a long-lasting barrier against future infestations. It sheds water away from the tile surface, prevents staining, and provides UV protection — all in a clear finish that preserves the original look of your roof.

Manufactured by RoofProtect at their Davie, Florida facility as a true liquid rubber coating — 100% without water, fillers, thickeners, or extenders. Every batch is the same proprietary formula refined over 30 years. The 5-Year Product Warranty is included standard. As our own slogan says: "Save Your Tiles."

Many homeowners search for a "roof painting" solution when they notice black streaks or algae — Fungal Shield is that idea taken to a professional level: a biocide-active clear formula engineered specifically to kill and prevent biological growth, not just cover it up.

Key Benefits

Active Biocide Formula
Kills algae, mold, and fungus at the cellular level — eliminates black streaking caused by Gloeocapsa magma bacteria.
Prevents Re-Infestation
Creates a permanent biological barrier that inhibits future mold, mildew, algae, and fungal growth.
Sheds Water & Prevents Staining
Waterproofs the tile surface and prevents biological staining from taking hold after application.
UV Protection
UV-stable formula protects tile surfaces from sun degradation under Florida's intense solar exposure.
Mildew Resistant — Guaranteed
Less cleaning required. Guaranteed mildew resistance is written into the product warranty.
Clear Finish
Preserves the original appearance of your tiles — no color change, no visible coating, just a protected roof.
Doubles as a Clear Metal Roof Coating
Bonds to metal roof panels the same way it bonds to tile — a clear, protective metal roof coating that stops rust-driven staining and biological growth without changing the panel's finish.

Frequently Asked Questions

Is Fungal Shield the same as bleach or pressure washing?

No — pressure washing and bleach treatments kill surface growth temporarily but provide no lasting protection. Fungal Shield bonds to the tile surface and creates a permanent barrier against re-infestation. It also doesn't risk the tile damage that high-pressure washing can cause on aged tiles.

Will Fungal Shield change the color or appearance of my tiles?

Fungal Shield is a clear coating. Your tiles will look the same — just cleaner and free of biological staining. The coating is not visible to the eye after curing.

How long does the 5-Year Warranty cover?

The 5-Year Product Warranty covers the mildew resistance and waterproofing performance of the Fungal Shield coating against defects in the product. Actual biological protection performance in Florida conditions typically runs beyond the warranty period.

Can Fungal Shield be combined with Smart Shield or Roof Shield?

Yes — Fungal Shield is frequently applied as a base treatment before Smart Shield or Roof Shield, particularly on roofs with a history of biological growth. All three systems share compatible base chemistries and are designed to work together.

Do you need to come out and inspect before applying?

Yes — we provide a free over-the-phone or on-site evaluation to assess the condition of your roof, identify the biological growth present, and confirm Fungal Shield is the right product for your situation.
