Snoop's Take

The Gardner-Gibson Sta-Kool 15-Year Turbo-Dri Elastomeric Roof Coating is designed to provide a protective and reflective finish for roofs, helping to keep them cool and durable against environmental wear. Customers have praised its quick drying time in warm weather, with one user noting that it dries in just about an hour in 80+ degree weather, allowing for immediate resistance to rain and other elements. Many users appreciate the long-lasting results when the coating is properly applied, with comments like, "A properly applied coating lasts for a long time." However, there are concerns about its effectiveness on pitched roofs and its compatibility with aluminum coatings, as some reviewers suggest that a new roof might be more beneficial than a coating. Overall, while the product has its drawbacks, particularly in specific applications, it is generally recommended for its category due to its benefits in temperature reduction and durability when applied correctly.
