Supplements and Estimating
Code Upgrade Supplements: Prove What the Code Requires
3 min read · updated July 2026 · MESHA Team
Who this is for
Public adjusters and independent adjusters who write, supplement, or defend repair estimates, and anyone tired of watching drip edge, ice barrier, and deck re-nailing lines disappear in desk review with the note "not required."
The problem
The problem is rarely the code. It is the proof. "Required by code" is an opinion until the file shows which code edition the jurisdiction adopted, which section applies to a repair of this scope, and who confirmed that it is enforced. Reviewers delete opinions. They pay documented requirements. The difference between the two is about an hour of verification work, done in the right order and saved in the right place.
