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.

GET THE BENEFITS OF USING AN EXPANDING MODIFIED POLYUREA ROOF COATING SYSTEM

The EXPANDOTHANE roof coating system much more than just water-resistant protection. It is a two-step application of a hybrid polyurea base coat and a UV resistant top coat that provides an unmatched level of waterproofing.

The base coat is a proprietary blend of polyurea that expands up to 7 times in volume filling cracks and voids forming a self-flashing, seamless 1/4″ waterproof membrane. This membrane adds structural integrity to any roofing substrate and is resistant to harsh chemicals, environmental damage, severe weather events and provides an unmatched level of protection for decades.

The top coat provides UV protection from the harsh rays of the sun and helps reduce roof temperatures up to 30 – 50 degrees. There are several material options and color choices available for top coating applications. Please consult with your sales representative to determine which product and color is best for your installation.
