Better Roof – Better Warranty

When we retrofit your entire roof with our unique silicone roof coating system, you won’t have to worry about costly leaks for two decades!

We cover your roof with a watertight seal that is so strong and effective, we include an industry-leading, full 20-year, parts-and-labor warranty. We don’t pro-rate your warranty. If you have a roof leak in the next 20 years, we cover the entire cost of resealing it!

We want to be your roofing company for life. Our silicone roof sealant is designed to last 20 years. And after 20 years, hire us to add another layer of silicone and you’ll get another 20-year warranty – without tearing off and replacing the original roof!

(Note: Small roof patches and partial repairs do not include a warranty.)
