Replacing Old Decking

In this Ask A Roofer minisode Henry the Arizona Roofer answers a homeowner’s question about installing new sheathing over old plank decking. Can you lay OSB on top or is full replacement the better move? Henry explains what to look for in your existing deck like rot, splits and loose boards and shares how to prep and tighten everything before adding new material. He also covers proper fastening, staggering joints for added strength and making sure your new sheathing lines up with the roof trusses.

Listen to the minisode.
