Products / Perma-Tite Expansion Joint

A prefabricated metal roof expansion joint cover in roof-to-roof and roof-to-wall versions that allows thermal movement between two roof systems, insulates against interior temperatures to limit condensation and uses a continuous cleat against wind-driven rain. An articulating cleat allows four-way movement, and it is supplied in 12-foot lengths with fasteners, attaching to wood framing on new or existing roofs. Covers are made in 22 or 24 ga. galvanized steel or .040, .050 and .063 in. aluminum. The product page prints a 20-year, 120 MPH Perma-Tite wind warranty.
