New London County, Connecticut Roofing Permit Requirements
In Connecticut, building permit requirements are primarily enforced at the local municipal level, rather than by county. This means that the specific rules and regulations for obtaining a roofing permit will depend on the town or city within New London County where your property is located. The state follows the Connecticut State Building Code (CSBC), which serves as the foundation for local ordinances.
For properties in unincorporated areas, it's essential to identify the governing municipality or authority responsible for building code enforcement. Typically, even areas not formally incorporated into a city or town will fall under the jurisdiction of a nearby municipality or a county-level administrative body for permit purposes. You will need to contact the building department of the closest incorporated town or the relevant county office to determine the specific requirements.
Generally, a building permit is required for most construction, alteration, or demolition projects that affect structural integrity, safety systems, or the use of a building. For roofing projects, a permit may be necessary if the work involves structural changes, such as replacing rafters or beams, or if it's a complete tear-off and replacement of the roof deck. Minor repairs or simple re-shingling might not require a permit, but it's always best to confirm with the local building official.
To obtain a permit, you will typically need to submit an application form, construction drawings or a site plan, and potentially documentation regarding energy code compliance. If a contractor is performing the work, their license and insurance information will also be required.
The City of New London's Building Inspection Division, for example, is the regulatory authority for the Connecticut Building Code and handles permits for new construction, repairs, and alterations.

Connecticut State Building Code and Roofing Legislation
As of March 2026, the state of Connecticut is in a transition period regarding its building codes. The current enforceable code is the 2022 Connecticut State Building Code, which is based on the 2021 International Building Code (IBC) and the 2021 International Residential Code (IRC). However, the state is in the process of adopting the 2026 Connecticut State Building Code, which will be based on the 2024 editions of the International Code Council (ICC) model codes. These new codes are expected to take effect in mid-2026.
Roofing requirements in Connecticut are governed by these state-adopted codes, which include specific amendments to address the state's climate, such as snow loads, ice dam prevention, and ventilation. Key requirements often include the mandatory use of ice and water shield membranes at eaves and valleys, specific underlayment standards, and proper attic ventilation to prevent moisture buildup.
Primary State Agencies
The adoption and administration of building codes in Connecticut are managed by the following entities:
- Office of the State Building Inspector (OSBI): This office, in conjunction with the Codes and Standards Committee, is responsible for the adoption and interpretation of the Connecticut State Building Code. It provides guidance, reviews modification requests, and ensures that state buildings comply with established standards.
- Codes and Standards Committee: This committee works directly with the Office of the State Building Inspector to develop, review, and approve the state's building code requirements.
- Local Building Departments: While the state sets the overarching codes, local building officials in each municipality are responsible for enforcing these codes, issuing permits for roofing projects, and conducting necessary inspections to ensure compliance.
