Keeping a flat or low-slope roof watertight and cool doesn’t require a specialty contractor—it requires the right coating. Gardner STA-Kool SK-7705 is a traditional acrylic elastomeric roof coating built to seal, protect, and reflect heat away from your roof surface, and this 5-gallon pail covers a substantial area in one application.
Made in the United States, this white coating goes on as a liquid and cures into a flexible, rubber-like membrane that expands and contracts with temperature swings instead of cracking. That elasticity is what separates a true elastomeric coating from a basic paint-like sealant—it stays intact through freeze-thaw cycles and summer heat, reducing the chance of new leaks forming at seams, flashing, and fastener points.
Who Is This For?
This product is aimed at homeowners, property managers, and roofing contractors dealing with metal, single-ply, modified bitumen, or built-up roofs that need a protective, reflective topcoat. It’s a practical choice for anyone trying to extend the life of an aging roof without a full tear-off and replacement, or for new roof installations where a reflective white finish helps cut cooling costs. DIYers comfortable with roller or sprayer application on ladders and roof surfaces will find this a manageable weekend project, while contractors will appreciate the consistent, professional-grade formulation in a job-ready 5-gallon size.
Bottom Line
Gardner STA-Kool SK-7705 delivers what it promises: a flexible, weather-resistant, reflective coating that helps stop leaks and reduce heat buildup on suitable roof types. The 5-gallon pail is sized for real coverage, not small touch-ups, making it a cost-effective option compared to buying multiple smaller containers. If you’re maintaining or protecting a roof and want a proven acrylic elastomeric formula rather than an unproven off-brand alternative, this is a straightforward, no-nonsense choice worth adding to your roofing supplies.
