Do You Need a Permit to Replace a Roof in Indiana?

It Depends on the Scope of Work

Roof replacement permit requirements in Indiana vary significantly by jurisdiction and by the type of work being done. The key distinction most building departments make is between a like-for-like replacement and a structural change.

When You Likely DO Need a Permit

Changing the roof structure — Adding dormers, changing the pitch, raising the roofline, or modifying trusses
Adding a new roof layer over multiple existing layers — Most codes limit the number of shingle layers (typically 2 maximum)
Converting roof type — Switching from shingles to metal, tile, or other materials that change the structural load
Commercial roof replacement — Commercial properties almost always need a permit for roof work
Roof repair after storm damage — If the repair involves structural work beyond just replacing shingles

When You Might NOT Need a Permit

Like-for-like shingle replacement — Tearing off old shingles and replacing with the same type of roofing material, with no structural changes
Minor repairs — Patching a small area, replacing a few damaged shingles, fixing flashing

County-Specific Examples

Carroll County explicitly states that same-roofline roof replacements are exempt from building permits. If you’re replacing shingles with shingles and not changing anything structural, no permit is needed.

City of Sullivan requires a building permit only if you’re changing the roof pitch or slope. A straight replacement with the same roofline is exempt.

Indianapolis — The Department of Business & Neighborhood Services generally does not require a permit for residential re-roofing (like-for-like), but does require one for commercial roofing and any structural changes.

Evansville/Vanderburgh County — Contact the Building Commission at 812-436-7885 to confirm whether your specific roof project needs a permit.

What a Roofing Permit Costs

When a permit is required, fees are typically on the lower end of the residential schedule:

Jurisdiction	Typical Roofing Fee
Floyd County	$40-$100 (based on scope)
Evansville / Vanderburgh County	$0.06/sq ft (minimum $100)
Parke County	$50 flat fee
Washington County	$50-$500 (based on scope)

Many jurisdictions roll roofing into their standard residential building permit fee. Call your local office for the exact amount.

Hiring a Roofing Contractor

Contractor Licensing

Indiana does not have a statewide roofing contractor license. However, many cities and counties require contractor registration:

Evansville requires a $25,000 surety bond, $1,000,000 liability insurance, and 3 hours/year continuing education
Fort Wayne / Allen County requires contractor registration with the ACBD
City of Gary has a specific Roofing contractor license category
Many rural counties have no contractor licensing requirement at all

What to Verify Before Hiring

Even in jurisdictions without licensing requirements, protect yourself by checking:

Insurance — General liability and workers’ compensation. Get a certificate of insurance naming you as additional insured.
References — Ask for recent local projects you can verify.
Written contract — Include scope of work, materials, timeline, payment schedule, and warranty terms.
Permit responsibility — Clarify in writing who is pulling the permit (if required). Most reputable contractors handle this.

The Inspection Process

When a roofing permit is required, inspections are typically simpler than for new construction:

Pre-work inspection (sometimes) — Inspector verifies the existing roof condition
Final inspection — Inspector checks the completed work for code compliance: proper underlayment, flashing, ventilation, and material installation

Some jurisdictions allow roofing inspections to be combined into a single final inspection after the work is complete.

Common Roofing Code Requirements

Regardless of whether a permit is required, Indiana building code sets standards for:

Ice and water shield — Required in valleys, around penetrations, and at eaves in cold weather zones
Underlayment — Required under all shingle installations
Ventilation — Attic ventilation must meet code minimums (typically 1:150 ratio)
Flashing — Proper step flashing at walls, chimney flashing, and valley flashing
Maximum layers — Generally limited to 2 layers of shingles. If you already have 2 layers, you must tear off before re-roofing.

Tips for Roof Replacement in Indiana

Call before you assume — A 5-minute phone call to your building department can confirm whether you need a permit. Don’t guess.
Get multiple quotes — Roofing prices vary significantly. Get 3 quotes and compare scope, materials, and warranty terms — not just price.
Check your insurance — Contact your homeowner’s insurance before starting. Some insurers require notification, and storm damage claims may cover part of the cost.
Timing matters — Roofing is seasonal in Indiana. Spring and fall are peak seasons with longer wait times. Plan ahead.
