Expert Verdict — Reviewed by the SuperArbor Pro Desk
Synthetic underlayment like FT SILVER is the modern default for steep-slope jobs: one 10 square roll covers what used to take multiple pallets of felt, and it stays flat in the wind during install. Keep laps within the printed overlap marks and don't exceed the 90-day UV window before covering. On very steep pitches or during hot-weather metal installs, check fastening patterns to match the deck type.
Even with a slip-resistant surface, synthetic underlayment is not a walking platform on steep roofs; use proper fall protection.
Order the FT Synthetics Silver 10 Square Underlayment roll for fast, reliable steep-slope coverage.
