Expert Verdict — Reviewed by the SuperArbor Pro Desk
Synthetic underlayment like Palisade has largely replaced #30 felt on steep-slope jobs because it is lighter, stronger and lays flatter with less wrinkle and tear risk. One roll per square makes takeoffs simple: a 25-square roof needs about three rolls plus a spare for laps. In HVHZ and Miami-Dade jurisdictions, keep the approval documentation (ESR-1847, NOA, FL-5325) on site for inspection.
Synthetic underlayment can be slippery when wet or dusty; wear slip-resistant footwear, use roof anchors per fall-protection requirements and follow the manufacturer's installation instructions and local code.
Order the SDP Palisade 10-square synthetic underlayment roll for lightweight, code-listed roof protection.
