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.
Use Marco’s RE2 instead of wood spacers to solve common re-roofing problems. Manufactured with quality, high-density polyethylene foam, RE2 is lightweight, strong and won’t decay or corrode the metal roof installed over it. In addition, RE2 will not warp, which causes the metal to crease.
