Deck Armor Underlayment
Deck Armor Premium Breathable roof deck protection protects your home while reducing trapped moisture at the same time. While this should be the goal of any underlayment material, many similar products do not actually fulfill this important requirement. Deck Armor, however, is guaranteed to do both and is backed by the Good Housekeeping Seal of approval.
Deck Armor is a better option than conventional organic felts because, unlike felts, it never absorbs moisture. Products that do absorb moisture can buckle and wrinkle, causing serious structural and decorative issues to the roof above. Because Deck Armor does not ever wrinkle or buckle, it ensures that shingles lay flat, increasing the protection they give to the home.
