What is Roof Deck Preparation?
Roofing Glossary · Installation
Definition
The process of inspecting, repairing, and preparing the sheathing surface before installing new roofing materials. This includes replacing rotted or delaminated decking panels, re-nailing loose sheathing to code specifications, installing H-clips at panel edges, and ensuring the deck is flat, dry, and structurally sound. Skipping deck preparation is a leading cause of premature roof failure and warranty voidance.
