Roof Maxx is a safe, easy, proven and affordable alternative to a complicated, expensive and life-disrupting asphalt roof replacement. Asphalt shingles aren't what they used to be. In fact, they include less asphalt than they once did, so they dry out and fail faster than ever before. Fortunately, Roof Maxx's revolutionary new technology uses natural plant based bio-oil to restore shingles' flexibility and instantly add five years of life to a roof.
