FAQs - Frequently Asked Questions

Roof Sheathing Code Requirements

What are roof sheathing codes?

Roof sheathing codes are the standards adopted by your local authority having jurisdiction that dictate what deck material, thickness, span and fastening a roof must have. These requirements ensure the sheathing can withstand snow loads, wind uplift and live loads specific to the location.

Why do roof sheathing codes matter when writing an estimate?

Using the wrong sheathing specification in your estimate, whether the wrong thickness, material or span, risks a supplement, a warranty dispute or a carrier rejecting the claim. The exact sheathing code gives adjusters and contractors a shared standard to work from and ensures the homeowner's roof is built correctly.

How can I use the OneClick Code Sheathing Report in my estimate?

Enter the property address and OneClick Code returns the local sheathing requirements automatically. Attach the report to your estimate to show both the AHJ's code requirements and how your estimate aligns with them, making your documentation defensible for carriers and accelerating review.

Is 7/16 OSB acceptable for roof sheathing?

It depends on the span rating and local code requirements. IRC Table R503.2.1(1) and APA Table 33 govern allowable spans and load capacities for different thicknesses. OneClick Code's report identifies the exact minimum thickness and span requirements for your specific jurisdiction so you know what qualifies before you spec the job.

What sheathing criteria does the OneClick Code report include?

The report covers material type (plywood or OSB), minimum thickness, allowable span between supports, fastening pattern and any special requirements, so you are working from verified code requirements rather than anecdotal numbers from past jobs.

How often does OneClick Code update its sheathing code data?

The system continuously monitors changes in building code editions and local amendments. When a jurisdiction revises its sheathing requirements, OneClick Code's team updates the database so you are always working with current information.
