Strafford County, New Hampshire, does not have a county-level building and safety division that issues permits for construction projects, including roofing. Instead, permitting authority rests with individual cities and towns within the county. This means that even for properties in unincorporated areas, you will need to contact the specific municipality where the property is located to inquire about and obtain the necessary permits. There are thirteen such jurisdictions within Strafford County.

- Rochester
- Somersworth
- Barrington
- Durham

For unincorporated areas, the general rule is that you must identify the specific town or city that governs that area and contact its building department directly for all permit requirements and application procedures. New Hampshire has very few unincorporated areas, with most land falling under a municipal jurisdiction.
When applying for a permit, typical requirements across New Hampshire municipalities include a completed application form, a site plan showing property boundaries and setbacks, construction drawings, and contractor information. Specific requirements can vary significantly from one town to another.

The following statewide building codes and regulations apply universally to all jurisdictions within New Hampshire:
New Hampshire Roofing Legislation, Codes, and Guidelines
New Hampshire State Building Code and Roofing Legislation
The State of New Hampshire mandates compliance with the New Hampshire State Building Code for the construction, alteration, and repair of buildings. As of the most recent updates, the state has adopted the 2021 editions of the International Code Council (ICC) model codes as the base standards. Specifically, residential roofing projects are governed by the 2021 International Residential Code (IRC), while commercial roofing projects fall under the 2021 International Building Code (IBC). These model codes are adopted by reference under New Hampshire Revised Statutes Annotated (RSA) Chapter 155-A, and they include specific New Hampshire amendments that must be followed.
The primary agency responsible for these standards is the New Hampshire State Building Code Review Board (BCRB). The BCRB is tasked with reviewing model codes, recommending legislation to adopt or amend them, and ensuring consistency in the application of building regulations across the state. While the state sets these minimum standards, enforcement is typically handled at the local municipal level by building officials. In municipalities that do not have a local building official or enforcement mechanism, the State Fire Marshal's Office holds authority for enforcement.
