 to that surface. RoofMax does something very similar for asphalt roofs, only they use this revolutionary new technology that soaks into old brittle shingles and it adds millions of microbeads of all natural bio oil to restore the flexibility and prepare them to better protect your home. I saw this for myself at a home that we were trying to sell in Florida and we thought we were going to have to replace the roof, but after the RoofMax treatment, all the shingles became very flexible once again and it was totally good to go for at least another five years.
