Use Marco’s RE2® instead of wood spacers to solve common re-roofing problems. RE2 acts as a spacer between the old shingles and the new metal roof, providing efficient airflow and ventilation. 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.
