BEEST RV Roof Coating White, 3.5 Gallon Covers up to 175 sqft (2 Coat)

- 3.5 gallon pail
- Covers up to 175 sq ft
- Water-based, solvent-free
Our take
Application is by brush, roller or quality sprayer after cleaning dust and debris off the surface, and the listing describes it as suitable for trailer roofs, metal roofs and flat roofs around the house.
Why it made the shortlist
This 3.5 gallon pail is a water-based, solvent-free liquid rubber coating sized for a whole roof rather than a patch. The listing states coverage of up to 175 square feet across two coats, and the maker's recommended minimum finished thickness works out to one gallon per 50 square feet, so the pail suits a mid-size rig.
Stepping up from the one gallon BEEST can in this guide buys volume at a lower cost per gallon, plus a single batch of material so the whole roof matches in sheen and thickness. It is the most expensive pick on the page, and the extra money goes entirely into quantity.
What works
- Whole-roof volume in a single pail
- Matching batch avoids visible patch lines
- Brush, roller or sprayer application
- Covers metal and trailer roofs alike
Watch out for
- Most expensive pick in this guide
- Heavy pail to carry up a ladder
