Do I need a permit for roof replacement in
New Albany, Indiana?

New Albany roof replacement permits — the key details

The rulebook is IRC R907 (reroofing and roof repairs), which New Albany adopts by reference in its local code. The critical threshold is 25% of roof area — anything over that, or any full tearoff-and-replace, requires a permit. What does 25% mean in practice? A typical single-story residential home is roughly 1,200–1,500 square feet of roof, so 25% is about 300–375 square feet (roughly 3–4 'squares' in roofing shorthand, where one square = 100 sq ft). If you're patching a section of damaged shingles over 15 squares, you need a permit. If you're doing 5 squares of spot repairs, you're likely exempt. The key: if you're tearing off the old material (not overlaying), you need a permit, period. New Albany Building Department will ask for a roof scope form showing dimensions, existing layer count, proposed material, and underlayment spec before they issue a permit. The city does NOT allow overlaying a third layer under any circumstance — IRC R907.4 states no more than two layers before tearoff is mandatory, and New Albany enforces this strictly.

New Albany's local climate context makes certain specifications non-negotiable. At 36-inch frost depth and Climate Zone 5A, ice-and-water-shield (also called ice-and-rain shield or self-adhering synthetic underlayment) must extend from the eave up the roof to at least 24 inches above the interior wall line of the building, per IRC R905.1.1 amendments for cold climates. This prevents ice dam leaks, which are extremely common in Indiana winters. Inspectors will check for this specification in your permit drawings and will verify it during the deck inspection before shingles go down. If you're using asphalt shingles, they must be rated for high wind (ASTM D3161, with proper fastening — typically 6 nails per shingle, placed 5/8 inch from the butt, or per manufacturer specs). Metal roofs are growing in popularity in the area, but a material change to metal triggers a structural evaluation (metal is lighter than asphalt, but the city wants engineering confirmation that your trusses and deck are adequate for the fastening load). Tile and slate changes require even more scrutiny because of the added dead load — expect 2–3 weeks for review.

Exemptions exist, but they're narrow. Repairs using the same material (shingle-to-shingle, metal-to-metal) under 25% of roof area do not need a permit — you can patch without filing. Gutter and flashing replacement alone, without touching the roof deck or shingles, is exempt. Reroofing a detached structure under 500 square feet (like a garage or storage shed) is often exempt if the structure is non-habitable and under 200 sq ft of living area. But the moment you're replacing more than one or two small sections, or you're doing a full tearoff, or you're changing materials, pull a permit. New Albany inspectors are reasonable and responsive, but they will catch unpermitted work during a property sale inspection or a neighbor complaint, and the cost to remediate is always higher than the permit fee upfront.

The permit process in New Albany is streamlined for straightforward like-for-like reroofs. You file online through the city's permit portal (accessible via the City of New Albany website — search 'New Albany Building Permit Portal' to find the link), or in person at City Hall. You'll need: your address, a scope form or PDF showing roof dimensions and existing layer count, proposed material (shingle grade/color, underlayment type, fastening pattern), and the name of your roofing contractor (if hired) or a statement that you're the owner-builder. The permit fee is typically $150–$300 for a standard asphalt shingle re-roof on a 1,500 sq ft roof (calculated at roughly $0.10–$0.20 per square foot of roof area, or a base fee plus $/square). For material changes or structural questions, add 1–2 weeks to the review. Once issued, your permit is valid for 180 days; you must obtain a pre-tearoff deck inspection before you remove the old roof, and a final inspection after all materials are installed and fasteners are countersunk/covered. The city typically schedules inspections within 2–3 business days of request.

Owner-builder work is allowed in New Albany for owner-occupied homes. If you're hiring a contractor, they typically pull the permit; if you're doing the work yourself, you can pull it as the owner. Either way, confirm that your roofing contractor is Indiana-licensed (if required for your scope — New Albany doesn't mandate a license for all reroofing, but many insurers and lenders require it). Have the contractor sign the permit as the 'responsible party' or you sign as owner-builder, and be present for both inspections. If you're planning a storm-related re-roof (hail, wind damage, insurance claim), coordinate with your adjuster early — the city will not issue a permit until the damage is documented, and your insurer may require a licensed contractor.

Three New Albany roof replacement scenarios

Climate and underlayment specs: why New Albany's cold winters matter

New Albany is in Climate Zone 5A with a 36-inch frost depth and winter temperatures regularly dropping below freezing for extended periods. This climate is ideal for ice dam formation — when melting snow refreezes at the eaves, it creates a dam that forces water back up under the shingles, causing interior leaks. The IRC code for cold climates (R905.1.1) mandates that reroofing jobs include ice-and-water shield extending 24 inches above the interior wall line (roughly the width of typical eaves overhang). New Albany Building Department inspectors will verify this specification is in your permit drawings and will check that the underlayment was actually installed before shingles go down — they do a pre-installation walkthrough, not just a final sign-off. Standard asphalt felt (30-lb) does not meet the ice-dam requirement; you must use a self-adhering synthetic (ice-and-water shield, or equivalent) rated for cold climates. This adds ~$0.25–$0.50 per square foot to your material cost but is non-negotiable and will save you thousands in water damage repairs down the road.

If you're installing metal roofing, the cold-climate requirement is different but equally critical. Metal roofs require a fully adhered vapor barrier or vented underlayment (depending on the metal roof system design) to prevent condensation buildup in attic spaces during freeze-thaw cycles. The city will require the metal roof manufacturer's technical data sheet showing the underlayment specification; a generic 'metal roof-rated synthetic' won't cut it. Metal roofs also require proper thermal expansion gaps and fastening patterns that account for expansion and contraction — materials expand and contract roughly 0.1 inches per 10 degrees Fahrenheit change, and Indiana winters can swing 60+ degrees in a week. Get this wrong and you'll have fastener pops and leaks within a few years. The city's inspector will ask to see the installation manual during the pre-installation inspection and will check fastening spacing and expansion gaps during the final walk.

Drainage and ventilation are also climate-specific. If your home has a low-slope roof or an attic with inadequate ventilation, roof rot and mold are common in New Albany's humid summers. The city's inspectors will ask about soffit/ridge vents during the permit review. If you're doing a full tearoff, it's an ideal time to add or upgrade ventilation (soffit vents, ridge vent, or power vent fan). This isn't strictly required for the permit, but it will extend your roof's lifespan and reduce moisture-related claims.

The two-layer rule and structural deck inspection: why tearoff timing matters

IRC R907.4 states plainly: no more than two layers of roof covering shall be installed on a roof at any time. If your inspection reveals two or more existing layers, you must tear down to the deck. New Albany enforces this strictly. Many older homes in New Albany (built in the 1950s–1980s) were reroofed without tearoff, so there are plenty of homes with hidden second or third layers. If your inspector (or the city, during pre-tearoff inspection) finds three layers, the permit is automatically modified to require a full tearoff. This delays your timeline by 1–2 weeks and increases costs by $1,000–$2,000 in additional labor and disposal. To avoid surprise, hire a qualified roofer who will do a thorough inspection and provide a written layer count before you pull a permit. Ask for photos or a video of the probe holes — documentation helps the city approve the scope without delays.

The pre-tearoff deck inspection is a critical step that many homeowners skip or rush through. The city WILL NOT approve a new roof on a rotted or undersized deck. If your inspector (or the city) finds structural issues during the pre-tearoff walk, you'll need to hire a structural engineer or a contractor to repair the deck before the city signs off. This can add $500–$3,000+ depending on the scope. New Albany's Frost depth of 36 inches means foundations can shift seasonally, and old homes sometimes develop roof rot in framing due to poor drainage or flashing. Have your roofer probe the deck thoroughly (at least every 2–3 feet along the perimeter and at any soft spots) and provide a damage map. If rot or inadequate fastening is found, get a written repair estimate upfront so there are no surprises.

Deck inspection also checks fastening. Asphalt shingles require fastening to solid substrate — plywood or boards at least 1/2 inch thick. Old homes sometimes have 1x6 wooden sheathing, which is adequate if properly spaced and fastened to the trusses, but loose or rotted boards will be flagged by the inspector. Metal roofs often require fastening to solid deck (not just purlins or straps), which is more expensive than asphalt shingles. Ask your contractor about deck fastening requirements for your chosen material and clarify costs upfront. The city's pre-tearoff inspection will confirm the deck is adequate before you remove the old roof.
