Step 1
Simply roll RE2 across the old shingled roof.
Step 2
Tack down RE2 with the 50 nails included.
Step 3
Install the metal roof on top.
Our RE2 spacers remove the re-roofing danger, expense, and hassle of wood furring for metal roofing retrofit projects. RE2 acts as a spacer between the old shingles and the new metal roof, providing efficient airflow and ventilation. It’s easy to handle and install, and it saves time and effort by eliminating tear-off—all at a price comparable to wood.

This vent keeps your system performing at its best by promoting efficient airflow to reduce lint buildup and excess heat, helping prevent moisture damage inside the home. Its enclosed design works to keep out insects, critters, and rain, while the removable cap makes cleaning and maintenance simple and fast. With leak-prevention features built into the design, it helps reduce customer call-backs and gives installers a dependable solution they can trust on every shingle roof application.
