Do I Need a Permit to Replace My Roof in New Jersey?

If you’re planning to replace your roof in New Jersey, you might be wondering whether you need a permit to get started. The answer can vary based on the type of property, the scope of the roofing work, and your local municipality’s requirements. This article will break down when a permit is necessary, the relevant regulations in New Jersey, and what homeowners need to know to ensure their roofing project goes smoothly.

Permit Requirements for Roof Replacement in New Jersey

As of March 5, 2018, New Jersey’s Department of Community Affairs (DCA) updated its guidelines to classify certain types of roofing work as “ordinary maintenance.” For single-family and two-family homes, roof replacement falls under this category, which means homeowners do not need a construction permit to replace or repair their roof on these types of residential properties. However, this exemption applies primarily to work that does not alter the structure or framework of the building.

When Permits Are Not Required

For single-family and two-family dwellings, the following types of roofing work generally do not require a permit:

• Replacement of Roofing Materials: Replacing shingles, tiles, or other roof coverings is considered ordinary maintenance.
• Repairs Without Structural Changes: If you’re simply repairing damaged shingles or tiles without modifying the roof’s structure, no permit is needed.
• Underlayment Replacement: Replacing the underlayment beneath the shingles typically does not require a permit for these types of homes.

Situations Where a Permit May Be Required

While many types of roofing work for residential homes do not require a permit, there are certain cases where one might still be necessary. These situations include:

• Commercial Properties or Multi-Family Residences: If your property is a commercial building, an apartment complex, or a multi-family residence with more than two units, the roofing work may require a permit. Replacing more than 25% of the roof covering for these types of buildings generally mandates a permit.
• Structural Changes: If your roofing project involves structural alterations, such as changing the roof’s pitch, adding dormers, or modifying load-bearing elements, you will need a permit, regardless of the property type.
• Extensive Re-roofing Projects: Some municipalities have specific ordinances that require permits for roofing projects above a certain size or scope, even for single-family homes.
