Expert Verdict — Reviewed by the SuperArbor Pro Desk
Synthetic underlayment like MaxFelt 30 replaces heavy felt, laying flat and staying walkable in heat. Roll it with the printed side out, maintain code-required laps, and use plastic cap fasteners rather than bare staples on exposed exposures. Order 5-square rolls for steep or small roofs where a 10-square roll is awkward to handle.
Synthetic underlayment can be slippery when wet or dusty; wear fall protection and non-slip footwear when walking on rolls.
Order MaxFelt 30 synthetic underlayment rolls for cooler, safer installations and proven weather protection.
