Does a metal roof need a vapor barrier?
Metal roofs and buildings require specific insulation and vapor barrier to meet the demands of condensation and breath-ability. Depending on whether your building is sheeted or not, or if you require insulation, we have it all, including the necessary tapes for installation.
