RafterDrafterTM is an innovative new design in

roof venting technology.

​

This new Patent Pending design promotes a fundamental resistance to the development of ice dams on your roof, by allowing maximum proper air flow under and through your roof's rafter bays, and by also allowing any extra heat that may leak up through your ceiling or attic floor into the attic and rafter bays to escape up through your roof's ridge vent without reaching the roof deck and shingles.
