The StratoShield Promise: If it doesn’t stay clean for 2 years, we come back free.
StratoShield™ — Two-Year Warrantied Cleaning
StratoShield is our flagship single-application service — one drone-applied pass that cleans and protects in the same step. No pre-wash. No second visit. We back it with a written 2-year warranty: if biological staining returns within 24 months, we re-treat at no cost.
How It Works
StratoShield is built around a quaternary-ammonium active — the same chemistry class used by Wet & Forget and Bio-Shield (the leading outdoor biocides in Australia and New Zealand). It’s a positively-charged molecule that’s attracted to the negatively-charged cell walls of mold, algae, mildew, and lichen. Once attached, it disrupts the cell membrane — the microbes leak their contents and die at the cellular level, killing the colony from the outside in.
In the same drone-applied pass, the formulation leaves a long-acting hydrophobic barrier on the surface that repels water, salt, and airborne spores at the chemical level for the next 30–36 months.
What to Expect — Timeline
StratoShield does not produce an obviously clean result on day one. The biocide kills the biofilm at the cellular level, and the dead biomass weathers off over the following weeks. For a typical Miami roof (where the dominant growth is surface algae rather than the thick moss and lichen mats common in cooler climates):
- First visible improvement: within 1–2 weeks, especially after rainfall.
- Most streaking gone: 4–8 weeks.
- Full clean: roughly 6–12 weeks, depending on sun exposure, wind, and rain.
Roofs with significant moss or lichen present (denser cell structures, more biomass to break down) typically take several months to fully clear.
Application Window
Once StratoShield is applied, the formulation needs about 12 hours of dry weather to bond and set. After that, rain accelerates the process — it carries dead biomass off the surface and reactivates a small amount of the residual coating with each rinse, which is part of how new spore germination is suppressed for 2+ years.
Works on Every Florida Exterior
Asphalt shingle and tile roofs. Concrete walls and stucco. Brick and natural masonry. Metal roofing and architectural panels. Painted and natural surfaces. Single chemistry, single visit, every common Florida exterior substrate.
What StratoShield Delivers
- 2-year written warranty. Free re-treatment if staining returns within 24 months. Actual re-treat rate under 6%.
- 30–36 months real-world life in Florida — replaces 3–6 standard wash cycles.
- No exclusivity. No multi-year lock-in. Cancel any time. Per-job POs accepted.
Standard Soft Wash vs. StratoShield
| Standard Soft Wash | StratoShield™ | |
|---|---|---|
| Visits | One | One |
| Cleans biological growth | âś“ | âś“ |
| Long-acting protective barrier | — | ✓ |
| Written warranty | — | 2 years |
| Typical real-world life | 6–8 months | 30–36 months |
| Best for | Recurring scheduled maintenance | Replaces 3–6 wash cycles |
Both services use manufacturer-warranty-compliant chemistry (GAF, CertainTeed, Owens Corning, Carlisle TPO, GenFlex EPDM). Both are FAA Part 107 drone-applied with a 2-meter sensor buffer. The difference is the StratoShield blend — and the warranty.
Is It Safe?
- Non-fluorinated, biodegradable formulation. Zero PFAS, zero fluorine, zero chromium, zero heavy metals.
- Quaternary-ammonium-based active — same chemistry class used by Wet & Forget and Bio-Shield (the leading outdoor biocides in Australia and New Zealand). The positively-charged molecules attach to the negatively-charged cell walls of mold, algae, mildew, and lichen and disrupt their cell membranes, killing the colony from the outside in.
- Plant-safe and pet-safe with post-rinse protocol. Drone delivery reduces overspray drift ~30% vs ground-pump. Pets return once dry (2–4 hours).
- Manufacturer-warranty compliant (GAF, CertainTeed, Owens Corning, Carlisle TPO, GenFlex EPDM). ARMA-endorsed for asphalt shingle.
- Approved for environmentally-sensitive properties — coastal preserves, reservoir-adjacent communities. SDS filed with property management before work.
What It Doesn’t Do
- It is not paint. It does not change the color or appearance of your surface.
- It is not a fix for damaged surfaces. If shingles are at end-of-life or stucco is cracked, address the underlying issue first.
The Warranty in Writing
- Covered: mold, algae, mildew, black streaks, pink bacteria, and lichen regrowth on StratoShield-treated surfaces
- Not covered: physical damage, hurricane debris, jet fuel exposure, or surfaces not treated under the StratoShield service
- Claim process: call or text us with a photo. Re-treatment visit scheduled within 14 days.
Backed by Licensed Expertise
StratoClean is led by Marcelo Pena, a State of Florida licensed mold expert. Every StratoShield treatment protocol — chemistry concentration, dwell time, surface compatibility — is calibrated by someone state-licensed to make those calls, not just by drone operators reading manufacturer pamphlets. And StratoClean is the only drone-cleaning operator in the US with a proprietary customer app for booking, scheduling, and job tracking.
