Roofing Permit Required Documents in Los Angeles

Documents and information needed to apply for a Los Angeles LADBS roofing permit.

What Documents Are Required for a Los Angeles Roofing Permit?

When applying for a roofing permit in Los Angeles, you must provide documentation that describes the scope of the roofing project and confirms that the materials and installation will meet LADBS and code requirements. Submitting complete and accurate documentation the first time helps avoid corrections, delays, and additional review cycles.

The specific documents required for your Los Angeles roofing permit depend on whether the project qualifies for an express permit or requires a plan check. Zermit AI helps prepare your permit documentation package so it is ready for LADBS submission.

Basic Information Required for All Roofing Permit Applications

All Los Angeles roofing permit applications — whether submitted online through PermitLA or in person at an LADBS district office — require the following basic project information:

• Property address and assessor parcel number (APN)
• Description of the roofing work being performed (e.g., full re-roof, partial replacement, new sheathing)
• Total roof area being replaced or re-roofed, measured in squares (100 sq ft each)
• Type of existing roofing material being removed
• Type of new roofing material being installed and its fire rating classification (Class A, B, or C)
• Applicant name and contact information (contractor or owner-builder)
• California Contractors State License Board (CSLB) license number if a licensed contractor is

performing the work

• LADBS permit application form (available through PermitLA or at LADBS district offices)

Roofing Material Documentation

LADBS requires documentation confirming that the roofing materials meet the required fire rating and any applicable energy code standards.

• Manufacturer specifications or product data sheet for the proposed roofing material
• Fire classification listing confirming the material's Class A, B, or C rating
• Cool Roof Rating Council (CRRC) certification for the proposed material, if Cool Roof requirements

apply to the project

• Underlayment specifications confirming compliance with the Los Angeles Building Code

Roof Plan Requirements

For most express permit roofing projects in Los Angeles, a detailed roof plan showing the module layout is not required. However, for projects that require a plan check — including those with structural modifications, new sheathing over open framing, or roof-mounted solar — a roof plan is required.

• Roof plan showing the overall dimensions and shape of the roof
• Location of all roof penetrations, skylights, and equipment
• Roof framing plan if structural modifications are involved
• Sheathing layout and fastening schedule if new sheathing is being installed
• Solar module and anchor layout if solar panels are being installed concurrently

Structural and Engineering Documentation

Projects that involve changes to the roof structure — such as replacing roof framing, modifying rafters, or installing heavy roofing materials — may require structural engineering documentation.

• Structural calculations prepared by a licensed engineer (if required by LADBS)
• Details for connections at ridge, eaves, and load-bearing walls
• Soils report if foundation modifications are involved
• Seismic and wind uplift calculations where applicable

Preparing Your Los Angeles Roofing Permit Application

Organizing your roofing permit documentation in advance helps ensure a smooth submission experience at LADBS. Confirm whether your project qualifies for an express permit — which requires less documentation and can be submitted entirely online — or whether a plan check is required.

Licensed roofing contractors familiar with the Los Angeles permit process often handle documentation preparation and permit submission on behalf of property owners. Zermit AI can also help identify exactly what documents your roofing project requires before you begin the application process at LADBS.
