About

About Expandothane ExpandoThane™ was created in 2004 and designed to provide property owners and facility managers with an affordable and guaranteed long-term solution to roof leaks and common water-related roofing problems. We introduced our rubberized hail-proof roof coating system because the industry just kept falling short on a guaranteed long-term solution that was cheaper than the cost of a installing new roof. Our customers choose ExpandoThane™ for superior protection, cost savings and peace-of-mind knowing that our roof coating system is backed by a 15-year guarantee. With a proven track record, ExpandoThane™ has been failure-fee since its introduction. If you are looking for a high-quality, cost-effective roof coating that will protect your structure many years to come, then ExpandoThane™ is the best product for you.
