Does the Building Permit Fee Cover a Roof Materials List Change?
You’ve picked out the perfect shingles, your contractor is ready to go, and then you realize you want a different material—but you’ve already paid the permit fee, so does that cover the change or are you on the hook for more?
TL;DR
The short answer is no—the building permit fee you already paid generally does not cover a change in roofing materials. Permit fees are typically calculated based on the project’s total valuation or a fixed rate, not the specific type of material. However, changing materials can trigger a whole new round of permit reviews because it affects structural load, fire ratings, and code compliance. Some jurisdictions require a new permit application or a revised plan review if the change is significant. The good news is that minor “like-for-like” changes often don’t require extra fees, but switching from asphalt shingles to heavy tile or metal will likely involve additional costs and inspections.
Key Takeaways
- Permit fees aren’t material-specific: Fees are usually based on project value or a fixed rate, not the type of shingles you choose.
- Material changes trigger code reviews: Switching materials often requires structural load verification and fire rating checks, which may involve extra plan review fees.
- “Like-for-like” is the exception: If you’re replacing the same material with the same material, no additional fees are typically needed.
- Plan check fees are separate: Many jurisdictions charge a plan check fee (often a percentage of the building permit fee) that covers reviewing your material specs.
- Always check before you change: Your contractor or local building department can tell you if a material change requires a revised permit application.
The Complete Guide to Building Permit Fees and Roof Material Changes
If you’re planning a roofing project, understanding how permit fees work is essential. Many homeowners assume that once they pay the permit fee, they’re free to change materials mid-project without any extra cost. That’s not quite how it works. Let’s break down what the permit fee actually covers and how changing your material choice affects your wallet and your compliance timeline.
How Building Permit Fees Are Actually Calculated
Building permit fees are rarely tied to the specific type of roofing material you choose. Instead, most local jurisdictions use one of two common methods:
- Project valuation method: The fee is based on the estimated cost of the entire project, including materials, labor, and equipment. For example, the City of Montreal charges $9.80 for every $1,000 of work, with a minimum fee for residential buildings [Ville de Montréal].
- Fixed fee method: Some jurisdictions charge a flat rate based on the type of work. Ohio, for instance, has a $275 processing fee plus a square footage fee for re-roofing permits [Ohio Department of Commerce].
The permit fee covers the administrative cost of reviewing your application, issuing the permit, and conducting inspections. It doesn’t include the cost of the materials themselves—that’s a separate expense you pay to your supplier or contractor.
When Changing Materials Costs You More
At first glance, you might think switching from one material to another shouldn’t matter since the permit fee is based on project value. But here’s where things get interesting: when you change materials, you’re changing the scope of the project from a code perspective. That’s where additional fees can creep in.
Structural Load Verification
One of the most common reasons a material change requires extra review is structural load. If you switch from lightweight asphalt shingles to heavy clay tile or metal, the existing roof structure may not be designed to handle the additional weight [Ohio Building Code]. Your building department may require a design professional to evaluate and certify that the structure is adequate for the new materials [Ohio Department of Commerce]. This review often comes with a fee or requires you to submit revised plans, which may trigger an additional plan check charge.
Fire Rating and Code Compliance
Different materials have different fire ratings. If your jurisdiction requires specific fire classifications for roofing materials—especially in wildfire hazard zones—changing materials means your plans need to be re-evaluated [City of Bend]. The construction documents must show the roof materials and assembly classification in accordance with local codes [Ohio Building Code]. This can result in additional plan review time and fees.
Plan Check Fees Are Separate
Many jurisdictions separate the plan check fee from the building permit fee. The plan check fee covers the cost of reviewing your construction documents to ensure they comply with codes. For example, one California city charges 85% of the building permit fee as a plan check fee [City of Lawndale]. If you change materials, your plans need to be reviewed again, which may incur an additional plan check fee.
“If the roof materials and assemblies are changed, the design professional shall evaluate and certify the structural load design of the existing roof is adequate for the new roof materials and/or assemblies.”
When Changing Materials May Not Cost Extra
There is one scenario where changing materials likely won’t cost you extra: when you’re replacing like-for-like. If your permit application specified asphalt shingles and you switch from one brand of asphalt shingles to another, or from one color to another, that’s typically considered a minor change that doesn’t require additional review or fees.
Many homeowners are surprised to learn that a “like-for-like” replacement—even if the new material looks different—often doesn’t trigger additional permit costs as long as it’s the same material type and weight.
Similarly, if the jurisdiction allows you to make the change and simply notifies the inspector on-site, you may avoid extra fees. However, this varies widely by jurisdiction, so it’s always best to check.
What the Permit Fee Covers (and What It Doesn’t)
To really understand the question, it helps to know what you’re paying for. The building permit fee typically covers:
- Administrative processing of your application
- Initial plan review to ensure code compliance
- Inspections during and after the work
- Issuance of the permit and certificate of occupancy (if applicable)
What it doesn’t cover:
- Additional plan reviews triggered by material changes
- Structural engineering assessments required for material changes
- Re-inspection fees if the work doesn’t pass inspection
- Permit extensions if the project takes longer than the validity period
One detail many homeowners overlook is that some jurisdictions require a permit for changing roofing material even if the structural work is minor. For instance, the City of Bend requires a building permit if you’re changing the type of roofing material—say, from shingles to metal—even without structural modifications [City of Bend].
Always discuss any material changes with your contractor before work begins. A good contractor will know whether the change affects your permit and can guide you on the process.
Common Material Change Scenarios and What They Cost
To help you plan, here’s a quick reference table comparing typical material changes and their likely permit implications.
| Change Scenario | Likely Permit Impact | Potential Extra Costs | Notes |
|---|---|---|---|
| Asphalt shingles to different asphalt shingles (like-for-like) | None—no permit revision needed | $0 (no extra fees) | Considered a minor change; inspector can be notified on-site |
| Asphalt shingles to metal roofing | Permit revision likely required | Plan check fee (85% of permit fee in some areas) + engineering review if needed [Ohio Building Code] | Weight change triggers structural review; fire rating may differ |
| Asphalt shingles to clay/concrete tile | Permit revision and structural certification required | Plan check fee + structural engineering fees ($300–$2,000+) [Wellbuilt Florida] | Significant weight increase; often requires engineer certification |
| Shingles to cedar shakes | Permit revision required in fire hazard zones | Plan check fee + fire rating review | Fire resistance concerns; may be restricted in wildfire zones [City of Bend] |
| Color change only (same material) | None—no permit revision needed | $0 | Considered a cosmetic change; no structural impact |
Frequently Asked Questions About Permit Fees and Material Changes
Does the building permit fee cover a change from shingles to metal roofing?
No. Changing roofing materials typically triggers a permit revision because of structural load and fire rating considerations. Your permit fee covers the initial review and inspections, but a material change may require a new plan check and additional fees [City of Bend].
Will I have to pay the full permit fee again if I change materials?
Usually not the full fee, but you may have to pay additional plan check fees or revision fees. Many jurisdictions charge a percentage of the original permit fee for revised plan reviews, such as 85% of the building permit fee [City of Lawndale].
Can I change my roofing material after the permit is issued without notifying anyone?
That’s risky and generally not recommended. If the inspector shows up and sees material different from what’s on the approved plans, you could fail inspection and be required to redo the work or apply for a revised permit [Ohio Building Code]. Always notify your building department first.
Does the permit fee depend on the cost of the roofing materials?
Not directly. Permit fees are usually based on the total project valuation (materials + labor) or a fixed rate. Higher-cost materials can increase the project valuation and therefore the permit fee, but the fee isn’t specifically “for” the materials [Ville de Montréal].
What if I change from asphalt shingles to a material with a different fire rating?
This almost always requires a permit revision. Fire-rated roof assemblies are a code requirement, and your construction documents must show the assembly classification [Ohio Building Code]. The building department needs to verify the new material meets the required fire rating for your area.
If I already paid the permit fee, can I get a refund if I don’t change materials?
Permit fees are generally non-refundable once the permit is issued. Some jurisdictions may refund a portion if the project is canceled before plan review begins, but this varies widely [Ville de Montréal].
Can my contractor handle the material change and permit revision for me?
Yes—a good contractor will manage the permit process and can notify the building department of material changes. However, be prepared for potential delays and additional fees if the change is significant. Always ask your contractor to clarify any additional costs before making a material change [Ohio Building Code].
Planning ahead is the best way to avoid unexpected permit costs. When you submit your initial permit application, think carefully about the materials you want to use. While you can change your mind later, doing so often means more time, more paperwork, and more money. A little extra thought upfront can save you a lot of hassle down the road.
Before you commit to a roofing material, check with your local building department to understand how a future change might affect your permit and your budget.
