Do You Need a Roofing Permit in Plano? What the City Checks on a Re-Roof

Do you need a permit to replace your roof in Plano? For almost any full replacement, yes. The rule is short, but the details around it decide how the job is scheduled, who signs what, and what a city inspector will want to see in your attic before the work is closed out.

This guide covers the Plano roofing permit from the homeowner's side: where a repair ends and a permitted re-roof begins, which code applies, what the inspections cover, and who should pull the permit. Each point links to the City of Plano document it comes from.

When Does a Plano Roof Job Need a Permit?

A Plano roof job needs a permit once it goes beyond a quarter of the roof. The city's Re-Roof Residential Permit Requirements handout states that re-roof work not exceeding 25% of the roof does not require a permit, which means anything larger does. A full tear-off and replacement is always on the permitted side of that line.

In practice, the 25% figure separates two kinds of work. Replacing a handful of wind-lifted shingles, resealing a pipe boot or rebuilding one small valley is ordinary roof repair and normally stays under the threshold. Replacing whole slopes after hail, or the entire roof at the end of its life, does not.

The grey zone is a partial replacement, such as redoing the two slopes that faced a storm. Measure it against the whole roof rather than guessing. If the work is close to a quarter, a call to Building Inspections before the crew arrives costs nothing and settles the question.

Which Building Code Applies to a New Roof in Plano?

A new roof in Plano is held to the 2024 International Residential Code as adopted, with local amendments, by Ordinance No. 2025-6-15. That ordinance repealed the city's previous residential code ordinance, which had adopted the 2021 edition, so a roof installed today answers to the newest version of the model code the city has taken on.

The city's amendments to the roofing chapter are narrow. The main one, to Section R902.1, allows non-classified roof coverings only on small one-story detached accessory structures, such as a tool shed or playhouse of 120 square feet or less. A house roof does not get that exception, so the covering on your home has to carry a fire classification.

The re-roof handout itself cites an older code edition, so some of its section numbers may not match the current book. Your contractor should work from the code in force when the permit is issued.

What Material Rules Does Plano Spell Out for a Re-Roof?

Plano's re-roof handout lists a short set of material and installation rules that apply on top of the general code. They are worth reading before you choose a product, because a few of them change the scope and the price of the job:

• Shingles or shakes must be rated at least Class C for fire resistance.
• Unpackaged shingles, sold as seconds, are not allowed.
• Rotten decking or rafters have to be replaced as needed, not covered over.
• Where the existing roof is wood shake, slate, clay or cement tile, or asbestos-cement tile, it must be removed before the new covering goes on.
• Metal roofing, whether panel or shingle, and concrete and clay tile need a non-combustible underlayment.
• Wood shingle and shake roofs require solid wood decking beneath them.
• Roof systems in place before January 18, 1988 fall under a separate City of Plano amendment.

That last point matters on Plano's older streets, such as those near Los Rios Boulevard, where some homes predate 1988. If yours is that age, ask up front how the older roof system will be handled, because the answer can add a full tear-off and new sheathing to the scope.

What Does the City Inspector Check?

The city inspector checks that the new roof was installed correctly and that the work did not disturb anything else in the house. The re-roof handout describes two inspections, and which ones you get depends on the material.

The partial final inspection

A partial final inspection is required on metal panel, metal shingle, and concrete and clay tile roofs. It happens before the finished covering hides the underlayment, so the inspector can confirm the non-combustible layer is in place. For those materials, the crew has to pause at the right stage and the inspection has to be booked into the schedule, not added at the end.

The final inspection and the attic

Every permitted re-roof gets a final inspection to verify that the materials were properly installed and comply with code. Since June 1, 2003, the city has also required an attic check as part of that final. According to the city's Certification of Final Roof Installation form, the inspector looks at vent piping through the roof, confirms the rafters are in position, and checks that water heater and furnace exhaust vents were reinstalled properly.

That attic step exists for a reason. Tearing off a roof means removing and resetting the flue caps and vent pipes that pass through it, and a gas appliance vent left loose or disconnected can spill exhaust into the attic instead of carrying it outside. Nothing about it shows from the street, which is why the city goes up the ladder to look.

Can a Homeowner Waive the City's Final Inspection?

Yes, a Plano homeowner can waive the city's final roof inspection, but the permit is still required. The Certification of Final Roof Installation form lets the owner certify that the roofing contractor performed the final inspection instead. The form asks for the project address, the permit number, your printed name, signature and phone number, and it can be emailed or faxed to Building Inspections.

Signing it means you are vouching for your contractor's check, not the city's. Before you do, ask for photographs of the vent pipe connections, the water heater and furnace flues, and the rafters from inside the attic. If the contractor cannot produce them, booking the city inspection is the safer choice.

Who Should Pull the Permit, You or the Roofer?

In most cases the roofer should pull the permit, because Plano expects roofing companies to be registered with the city. The city's Contractor Registration Requirements handout places roof companies under the general contractor category, lists a current driver's license as the requirement, and sets an annual registration fee of $100. A roofer working regularly in Plano should be able to tell you they are registered without hesitation.

The exception is narrow. The re-roof handout says a homeowner who is performing the work personally, on a property that is their homestead, does not have to register as a general contractor. That allowance is for owners doing their own roof, not for a contractor who would rather the permit sit in your name.

If a roofer suggests you apply for the permit yourself while their crew does the work, treat it as a warning sign. The permit holder is the party the city looks to when an inspection fails, and you want that to be the company doing the installation.

How Does the Permit Fit Into a Storm-Season Replacement?

After a major hailstorm, the permit becomes one of the simplest ways to separate an established contractor from one passing through. Crews arriving from outside the area after a storm still have to register and permit their work in Plano like anyone else, and a request for the permit number before the tear-off is a quick test of whether that has happened.

Insurance work does not change the rules. An adjuster's scope decides what the policy pays for; it does not replace the city's permit or inspections. If the claim covers decking, the handout's requirement to replace rotten sheathing and rafters lines up with what a careful storm and hail damage roof repair scope should already include.

Permit fees come from the city's fee schedule, not the contractor, so ask for the fee as its own line on the estimate. The handout also reminds homeowners to check HOA deed restrictions and covenants, a separate approval from the city permit.

The Question to Ask Before Anyone Tears Off a Shingle

Ask for the permit number, in writing, before the first bundle goes up the ladder. That one request tells you the contractor is registered with Plano, the job was sized correctly against the 25% line, and an inspection or a waiver you chose will close it out.

Then decide how the final will be handled. Leaning toward the waiver? Agree in advance on the attic photographs you will receive. Metal or tile? Confirm the partial inspection is scheduled. Keep the permit record with your home's paperwork for a future buyer.
