FAQs - Frequently Asked Questions

Roof Sheathing Code Requirements

Q: What are Roof Sheathing Codes?

Roof sheathing codes refer to the specific standards adopted by your local authority having jurisdiction (AHJ) that dictate what type of deck material, thickness, span, and fastening a roof must have. These regulations dictate what sheathing specifications and requirements are compliant, acceptable for manufacturer warranties, and ensure roofs are constructed properly to withstand various types of severe weather including snow and ice.

Q: Why do roof sheathing codes matter when writing an estimate?

When you include incorrect sheathing specification in your estimate—thickness, material, or span—you risk a supplement, a warranty dispute, or a carrier rejecting the estimate you submitted for your roofing job. Using the exact sheathing code allows adjusters and contractors to agree on installing to the right standard and ensuring the homeowner’s roof replacement is constructed properly

Q: How can I use the OneClick Code Roof Sheathing Codes Report in my estimate or claim review?

Using OneClick Code, you simply enter the project’s property address, and the report indicates the local sheathing requirements automatically. You attach the report to your estimate or claim, showing both the code requirements enforced by the authority having jurisdiction and how your estimate aligns with it. This makes your documentation defensible for carriers and accelerates the review time, so you can close roofing jobs out faster.
