Expert Verdict Reviewed by the SuperArbor Pro Desk

The 4 in. length suits re-roof recover jobs where thick polyiso sits between panel and deck. Verify total fastening depth before ordering so the screw engages the deck properly, and use a depth-adjustable driver to avoid stripping or overdriving.

Drill point screws leave sharp tips and swarf; wear eye protection and cut-resistant gloves during installation.
