Questions & Answers

Can it be used on mobile home ?

Asked by: JJ
Hello, Weather Watch is intended for use on a steep slope roof underneath asphalt shingles. It is not intended for use on flat roofs or as the primary roof covering. You may want to consider Liberty Self-Adhering Roof Roofing as an alternative.
