Roof Hugger offers two retrofit systems for existing metal roofs.

Roof Hugger, Lutz, Fla., offers two retrofit systems for existing metal roofs. The one-piece “nesting” attachment system goes on fast and meets all codes. The sub-purlin allows any style of new metal roof panel to be quickly installed as if it were a new building. Webtherm™ thermal isolating spacers are designed for cold climates where efficient insulation is essential. This product eliminates “cold bridging,” which causes interior frost and condensation, by completely isolating all metal-to-metal or metal-to-fastener conductive contact.
