Do you need a permit to replace or repair your roof? In many cases, a full roof replacement or reroof requires a building permit, while small repairs may not. The exact requirements depend on where the property is located, the scope of the work, and the type of roofing project being performed.
For properties in the City of Los Angeles, the Los Angeles Department of Building and Safety (LADBS) has specific requirements for reroofing, including rules covering roofing materials, existing roof layers, fire ratings, roof sheathing, and inspections.
If you are planning roof work, it is important to confirm the requirements with the building department that has jurisdiction over your property before work begins.
Do You Need a Permit to Replace a Roof?
A full roof replacement will generally require a building permit. Roof replacement involves substantially more than routine maintenance and may include removing existing roofing, inspecting or replacing roof sheathing, installing underlayment, and installing a new roof covering.
A permit allows the local building authority to verify that applicable building and safety requirements are being followed. These requirements can involve the roofing material itself, fire classification, structural conditions, installation methods, and inspections.
Requirements vary between cities and counties, so homeowners should not assume that the rules in one jurisdiction apply everywhere.
Do Roof Repairs Require a Permit?
Whether a roof repair requires a permit usually depends on the extent and nature of the work.
Small maintenance projects, such as replacing a limited number of damaged shingles or repairing a minor leak, may be treated differently from a reroof or major repair. More extensive work may require a permit, particularly when the project involves a significant portion of the roof or affects structural components such as roof decking, rafters, or framing.
Because the line between maintenance and work requiring a permit varies by jurisdiction, contact your local building department when you are unsure.
Do You Need a Permit to Replace Roof Shingles?
Replacing a few individual shingles as part of routine maintenance may not be treated the same as replacing shingles across an entire roof.
If the project involves reroofing a substantial portion of the building or replacing the existing roof covering, a permit may be required. The amount of existing roofing that can remain in place and the types of materials that can be installed over an existing roof can also be regulated by local building codes.
Do You Need a Permit for a New Roof?
New roof construction generally falls within the permitting process for the building being constructed. This includes the roof on a new home as well as roofs constructed as part of additions, garages, and other permitted structures.
The plans and inspections associated with new construction allow building officials to verify that the roof assembly complies with applicable structural, fire, weather protection, and other building requirements.
Do You Need a Permit for a Roof Overlay or Layover?
A roof overlay, sometimes called a roof layover, involves installing a new roof covering over an existing roof rather than completely removing the old material.
Whether an overlay is permitted depends on the existing roofing material, the number of existing layers, the condition of the roof deck and structure, and local building requirements.
In the City of Los Angeles, LADBS allows existing roof coverings to remain under certain circumstances when the roof structure can support the additional weight, the sheathing is structurally sound, drainage is adequate, the existing roofing is securely attached, insulation is not water-soaked, and applicable fire requirements are maintained.
However, LADBS does not allow reroofing over existing wood shakes or wood shingles. Those materials must be removed before a new roof covering is installed.
You can review the current City of Los Angeles reroof requirements on the LADBS reroof information page.
Do You Need a Permit When Changing Roofing Materials?
Changing from one type of roofing material to another can create additional building-code considerations. Roofing materials vary in weight, fire classification, installation requirements, and the type of roof deck or structure needed to support them.
For example, replacing asphalt shingles with a substantially heavier roofing material may require evaluation of the existing roof structure. Local requirements may also regulate the fire classification of roofing materials, particularly in areas with elevated wildfire risk.
If you plan to change roofing materials, confirm that both the material and proposed roof assembly are approved for the property before ordering or beginning installation.
Do You Need a Permit to Replace Your Roof Yourself?
Doing the roofing work yourself does not automatically eliminate permit requirements. If the project requires a permit, performing the work as a homeowner rather than hiring a roofing contractor does not by itself make the project exempt.
Depending on the jurisdiction and project, a property owner may be able to obtain a permit as an owner-builder. Owner-builders can also have additional responsibilities under California law, so it is important to understand those requirements before choosing to perform or manage the work yourself.
If you are planning a DIY roof replacement, contact the building department responsible for your property before beginning demolition or purchasing materials.
Who Gets the Roofing Permit?
When a licensed roofing contractor is performing the work, the contractor will often obtain the required permit as part of the project. Homeowners should confirm who is responsible for obtaining the permit before work begins.
Ask for the permit number and verify that the permit accurately describes the work being performed. Do not assume a permit is unnecessary simply because a contractor says one is not required.
If you are acting as an owner-builder, obtaining the necessary permit may be your responsibility.
Do You Need a Roof Replacement Permit in Los Angeles?
If the property is located within the City of Los Angeles, reroofing is regulated by LADBS. The city provides a reroof permitting process and specific requirements for roof coverings, sheathing, existing roof layers, fire classifications, and inspections.
One important distinction is that the City of Los Angeles and Los Angeles County are not the same permitting jurisdiction. Properties in incorporated cities within Los Angeles County may be regulated by their own city building departments, while other properties may fall under county jurisdiction.
Before relying on Los Angeles-specific requirements, verify which building department has jurisdiction over the property’s address.
Roofing Material Requirements in Los Angeles
LADBS requires approved roof coverings and establishes additional requirements for properties located in designated fire areas. Certain reroof projects in these areas must use an approved Class A roof covering.
LADBS also has rules governing how much existing roofing may remain in place, the condition of the underlying sheathing, and the installation of new roofing over existing materials.
If you are purchasing materials for a Los Angeles roofing project, make sure the roofing system you select is appropriate for the applicable building requirements and the specific property.
Does a Roof Permit Require an Inspection?
Permitted roofing work may require one or more inspections, depending on the project and the condition of the existing roof.
For City of Los Angeles reroof projects, LADBS states that when existing solid sheathing can be readily verified, only a final inspection may be required.
When the existing sheathing cannot be easily verified or new solid sheathing is installed, two inspections may be required. The first allows the inspector to verify the sheathing before roofing material or underlayment is installed. The second takes place when the reroof installation is complete.
The inspection requirements for your particular project should be confirmed with the building department or inspector responsible for the permit.
What Happens if You Replace a Roof Without a Permit?
Performing work without a required permit can create problems beyond the roofing project itself. Depending on the jurisdiction and circumstances, a property owner may be required to obtain a permit after work has begun, expose completed work for inspection, correct work that does not comply with applicable codes, or pay additional fees.
Unpermitted work can also become an issue when a property is sold or when future permitted improvements are made.
If roofing work has already been completed without a permit and you believe one may have been required, contact the local building department to determine the appropriate next steps rather than assuming the work cannot be corrected.
How Do You Find Out if Your Roofing Project Needs a Permit?
The safest way to determine whether a roofing permit is required is to contact the building department with jurisdiction over the property.
Before contacting them, have basic information about the project available, including:
- The property address
- Whether the project is a repair, partial reroof, or complete replacement
- The approximate amount of roofing being replaced
- The existing roofing material
- The new roofing material you plan to install
- Whether existing roofing will be removed or covered
- Whether roof decking or structural framing will be repaired or replaced
Providing these details can help the building department determine which requirements apply to the project.

Doing the work yourself does not automatically exempt a roofing project from permitting requirements. Homeowners may be able to obtain a required permit as an owner-builder, depending on the project and jurisdiction.
Do I need a permit to replace roof shingles?
Replacing a few damaged shingles may be considered maintenance, while replacing shingles over a substantial portion or all of the roof may be considered reroofing and require a permit. Check the rules that apply to the property.
Do I need a permit to put a new roof over an existing roof?
Roof overlays are regulated by local building requirements and may require a permit. The number and type of existing roof layers, structural capacity, condition of the sheathing, and proposed roofing material can all affect whether an overlay is allowed.
Who is responsible for getting a roofing permit?
