Expert Verdict — Reviewed by the SuperArbor Pro Desk
Synthetic underlayment like MaxFelt XT is the right pick when crews will be exposed on the deck or when a roof will sit exposed between tear-off and shingle install. Overlap per the printed roll guide and step overlaps at rakes to keep water shingled downward. Choose the 10-square roll to cut changeovers on large reroofs.
Synthetic underlayment surfaces can be slippery when wet or frosty; wear proper footwear and tie off on steep slopes.
Order MaxFelt XT 48" x 125' synthetic underlayment for traction and reliable secondary protection.
