Expert Verdict — Reviewed by the SuperArbor Pro Desk
Match plate size to the fastening pattern in your roofing system's FM or system spec; 3 in. plates are a common choice for through-fastened insulation attachment. Drive fasteners flush so the plate seats flat against the board without dimpling. Keep a spare bucket on hand for large insulation crews since plate counts run high per square.
Handle plates with gloves and drive fasteners with appropriate tools and eye protection on the roof.
Stock your next insulation job with TRI-BUILT 3 in. galvanized ribbed seam plates in a 1,000-count bucket.
