Expert Verdict — Reviewed by the SuperArbor Pro Desk
For steep-slope crews, FelTex offers the walking traction and deck grab that lighter synthetics often lack, making it a strong choice on pitches where slips and blow-off during exposure are concerns. Because one roll covers 10 squares, a mid-size roof takes only a few rolls, which speeds staging. Order per the 3/8-inch head nail requirement and check exposure limits in the current FelTex installation instructions before leaving it uncovered.
Synthetic underlayment surfaces can still be slippery when wet, frosty, or dusty, so use fall protection and follow OSHA roof work practices.
