Roof Replacement in New Orleans, LA: Materials, Permits and Fortified Roofs

Replacing a roof in New Orleans is three projects in one. There is the roof itself. There is the paperwork: a City permit backed by sixteen photographs and, in a historic district, an approval before the first slate comes off. And there is a question worth settling early, which is whether to build the new roof to the FORTIFIED standard that Louisiana’s grants and insurance discounts are tied to.

This page covers roof replacement in New Orleans, Louisiana from the first decision to the final certificate: when replacement is warranted, how the materials compare, what the FORTIFIED Roof standard requires, how the state grant program and the insurance discounts work, the City’s re-roofing permit step by step, the extra rules in historic districts, what happens on the roof, and what a named cost guide publishes. Each rule comes from the agency that sets it.

Roofer New Orleans is a referral service, not a roofing contractor. We connect you with an independent local roofing contractor, and the estimate, the permit, the contract and the new roof are that contractor’s work. The call is free.

When replacement is the right call

A roof does not have to be replaced because it has leaked. The City’s historic district guidelines suggest that replacement might be warranted when more than 20 percent of the slates, tiles or shingles on a roof are damaged or missing. They give an asphalt shingle roof an expected life of 15 to 25 years, with architectural shingles lasting longer. Slate and tile are another matter: the guidelines give slate 60 to 125 years and tile over 100, and urge owners to deal with local problems as they appear. The guidelines and the state grant program name three other signs.

• Asphalt shingles that have curled, turned brittle or lost their mineral coating
• A metal roof that is generally rusting, splitting, pitted or badly buckled, with many open seams
• A plan to apply for a Fortify Homes grant, which does not fund patching or partial repairs

If the damage is local, read the roof repair page first. Where both are possible, ask the roofer to price both.

Choosing the material

The choice comes down to four things: what the house had, what the historic rules allow, how the roof stands up to wind, and cost. The table sets the City’s lifespan figures beside the installed costs per square foot in HomeAdvisor’s national roof replacement guide, as updated on June 17, 2026.

Material	Life in the City’s guidelines	HomeAdvisor’s national cost per square foot	Historic district notes
Asphalt shingles	15 to 25 years, longer for architectural shingles	$3 to $7	Where the HDLC reviews the roof, the color should simulate slate, typically grays. Shingles are not on the French Quarter’s list of permissible sloped roofing.
Metal	No figure given	$7 to $13	The HDLC approves standing seam for all building types, but says metal is typically not appropriate on highly visible slopes or where the roof was historically slate.
Tile	Over 100 years	$10 to $20	Replacing tile with matching tile is reviewed by staff. The HDLC does not approve red asphalt shingles as a substitute.
Slate	60 to 125 years	$15 to $30 (slate or stone)	Replacing slate with slate is reviewed by staff. On a Significant or Contributing building, removing it for another material goes to the Commission.

HomeAdvisor’s figures are national. They are not New Orleans prices and they are not quotes.

Asphalt shingles

Asphalt shingles are the least expensive covering in the published figures. On a shingle roof in this climate, the parts you cannot see deserve the questions: how the deck is fastened, whether the deck is sealed, and how the edges are finished. Those are the items the Fortified standard addresses, and they are covered below.

Metal roofing in New Orleans

Metal became a popular roofing material after sheet metal production expanded in the mid-19th century, and the City’s guidelines describe several kinds found in New Orleans. Standing seam, with long raised seams running down the slope, suits steeper roofs. Flat seam metal, soldered at the joints, covers low-pitched galleries and porches. Corrugated and other paneled roofing was common on commercial and industrial buildings, sheds and garages.

Where no historic commission reviews the roof, the choice of panel is yours. Where the Historic District Landmarks Commission (HDLC) does review it, the Commission approves standing seam for all building types, 5-V crimp only for sheds, garages and some residential buildings, corrugated for sheds, garages, commercial buildings and overhangs, and R-panel or rib-panel only on non-contributing commercial buildings. Its guidelines favor natural metal or copper, or painted finishes from silver to gray or muted green, and say red metal roofs are generally not appropriate in the city. In the French Quarter, painted standing seam has to be formed on site.

Two technical points come from the same guidelines. Dissimilar metals corrode each other, so fasteners, flashing and panels have to be compatible. For storms, the City’s advice is double-lock seams and edges with closely spaced, high-strength fasteners.

Slate and tile

If the house has a sound slate or tile roof, the City’s guidance is to keep it going. When replacement cannot be avoided, owners in historic districts are strongly encouraged to match the original patterns and colors, and it is often possible to reuse salvaged tile. The guidelines also describe a storm measure for these roofs: a secondary, self-adhered roofing layer on plywood under the slate, tile or metal, which protects the house if the primary roof is damaged. Products that imitate slate exist, and the guidelines advise care with them, since they might not have the longevity promised.

Flat and low-slope roofs

Roofs pitched below 3:12 need a watertight roofing system: built-up roofing, single-ply roofing, modified bitumen or metal. The guidelines tell owners to check that the design deals with the building’s drainage, its substrate and its weight limits, and to weigh the system’s expected life in New Orleans’ climate and its hurricane resistance.

The Fortified Roof standard

FORTIFIED is a voluntary construction and re-roofing program of the Insurance Institute for Business & Home Safety (IBHS). The Louisiana Department of Insurance, which runs the state’s grant program, describes it as based on decades of IBHS research and sets out what the FORTIFIED Roof level requires.

• Stronger edges. A wider drip edge and a fully adhered starter strip, so wind cannot get under the roof edge and rip it away.
• A sealed roof deck. The deck is sealed to prevent the water damage that typically comes through exposed wood decking when the roof covering is blown off.
• Better attachment. Ring-shank nails in place of common smooth nails. The Department says this nearly doubles the strength of the roof against wind.
• Wind and rain resistant attic vents. IBHS lists these among the requirements.
• Impact-resistant shingles, as an option. A hail supplement calls for shingles that can withstand hail up to two inches in diameter.

A roof is not Fortified because a roofer says so. The designation is issued by IBHS after a FORTIFIED Evaluator, an independent third party, documents the work from start to finish. The Department says an evaluator is needed even when the owner pays for the roof without a grant. A designation lasts five years, is renewed by a re-inspection, and passes to the buyer when the house is sold. The roof covering can be shingle, metal or tile.

The Louisiana Fortify Homes Program

The Louisiana Fortify Homes Program (LFHP) is run by the Louisiana Department of Insurance. In the Department’s words, it grants up to $10,000 for homeowners to upgrade their roofs to the FORTIFIED Roof standard. Orleans is on the Department’s list of eligible parishes.

• Only primary residences with a homestead exemption qualify. New construction, condominiums and mobile homes do not.
• The home needs an active policy with wind coverage, and flood insurance if it is in a FEMA Special Flood Hazard Area.
• The grant covers construction costs only and is paid directly to the contractor when the work is complete and the FORTIFIED certificate has been issued. The owner pays everything above the grant, along with the evaluator’s fees, permits and inspections.
• During the grant process the homeowner submits at least three bids from contractors for the program’s review. The Department publishes a list of approved contractors.
• Patching and partial repairs are not eligible. The entire contiguous roof covering has to be replaced.
• Do not start early. A homeowner who selects a contractor and begins work before the program approves the project is not eligible.
• Open or past roof claims must be disclosed. The Department says the grant can be used to pay the difference between an insurance claim payment and the cost of an upgraded Fortified roof.

Insurance discounts, the endorsement and the tax credit

Once the work is complete, the homeowner receives a certificate that can be shared with the insurer for a discount on the premium, and the Department publishes a guide to Fortified roof discounts by insurance company. A newer rule firms this up. The Department’s Regulation 136 requires insurers to give premium discounts to residential properties with a FORTIFIED designation, applied to the hurricane portion of the premium, and the Department set January 1, 2027 as the latest date for insurers to have the discounts in place. Its benchmark table for the South zone, which takes in the parishes of the Louisiana Coastal Zone, lists 29 percent for a FORTIFIED Roof, 43 percent for Silver and 49 percent for Gold. The state’s coastal management office names Orleans among the coastal zone parishes.

Those are benchmarks applied to one part of the premium, not a promise about any bill. Ask your own insurer or agent what your policy would save before you count on a figure.

Two other state measures are worth knowing. The Department says Louisiana law requires insurers to offer a FORTIFIED endorsement on homeowners policies, which helps cover the added cost of rebuilding a roof to the standard after a covered loss. Act 404 also created a Fortified roof income tax credit. The Department describes it as a nonrefundable state credit covering up to $10,000 of qualified expenses incurred on or after July 1, 2025, with a statewide cap of $10 million a year issued first come, first served. It cannot be combined with a grant, and the Louisiana Department of Revenue handles the details.

The New Orleans re-roofing permit, step by step

The City requires a separate residential re-roofing permit whenever 50 percent or more of the roof on a single or two-family home is replaced, under Ordinance 30,235 MCS, which it announced in May 2025. The Department of Safety and Permits says the permit gives the owner a formal, independent record of the completed replacement, meant to help in qualifying for reduced insurance premiums or meeting the requirements of roofing grants.

1. Sign the estimate or contract. The City wants a copy signed by both the homeowner and the contractor. Its guide asks for both printed names, a list of labor and materials, and the total cost.
2. Photograph the house. The application needs a geotagged photo of the exterior and the existing roof. The City suggests a geotagging camera app with location services switched on.
3. Apply in the One Stop App. Processing takes 2 to 4 days. Properties in the HDLC or Vieux Carre Commission districts need that commission’s sub-permit first, which can take longer.
4. Pay the fee. It is $60, plus $30 in the historic districts, and it is paid after the application is approved. The permit is issued after payment and has to be posted where it can be seen at the work site.
5. Photograph each stage. Four wide-angle photos, from the front, left, right and rear, at each of four stages: the old roofing removed, the water-resistant underlayment on, the drip edge and flashing on, and the shingles or metal panels on. That makes sixteen. The City’s guide wants each set taken before the work is covered, so that the decking, the underlayment and the nailing can be seen.
6. Upload and notify. The photos go into the permit’s documents in the One Stop App, and the City’s inspectors are told by email that they are ready.
7. Keep the certificate. When the permit is closed the City issues a Certificate of Completion. File it with your insurance papers.

The City’s guide also carries technical lines a contractor has to meet. A drip edge is required at the eaves and rakes of a shingle roof. The underlayment has to be 30-pound felt or a synthetic of the listed standards, and 15-pound felt is not allowed. Shingles have to carry one of the listed wind test ratings or a Miami-Dade approval, and six fasteners per shingle is given as the standard.

State law backs the City’s rule. The state licensing board has told contractors that Act 239 of 2025 requires permitting and inspection of roof construction and reroofing for projects beginning on or after August 1, 2025, and that starting work before a permit is issued is a violation. The City’s guide to building permits sets the fee for work begun without a permit at two times the building permit price plus the regular permit fees. Buildings with three or more units or with business uses take a renovation permit instead. The City’s re-roofing permit page has the current steps.

Replacing a roof in a historic district

In the French Quarter, and in the districts where the HDLC has full control, the commission’s review is part of the permit. On the HDLC’s chart, full control covers Bywater, Faubourg Marigny, Holy Cross, Algiers Point, the Irish Channel, the Lower Garden District and St. Charles Avenue, along with the part of Treme between North Rampart Street and North Claiborne Avenue and the properties along Esplanade and Carrollton avenues. In Uptown, Mid-City and Parkview the HDLC’s jurisdiction is limited to demolition, although individual landmarks are reviewed wherever they stand. Ask the HDLC what applies at your address before you choose a material.

Where review applies, replacing a roof with the same material is the short route: HDLC staff can approve in-kind replacement, and in the French Quarter staff can approve traditional slate of the same quality, color and size as the existing roof. Changing the material is the long route. Under the HDLC’s guidelines, taking off slate or tile for something else goes to the Commission when the building is rated Significant or Contributing.

Details count too. The HDLC wants ridge tiles, cresting and finials kept, approves ridge vents only where there are no ridge tiles, and its staff give final approval of roofing colors. The strengthening work underneath is another matter: the City’s storm guidelines say connectors concealed within a building’s structure are not subject to HDLC review. The roofing contractor page lists the districts and covers both commissions’ rules, and the HDLC’s contact page lists the staff for each district.

What happens on the roof

Every contractor runs a job in their own way, and Roofer New Orleans does not direct their work. The City’s four photo stages make a fair outline of the work.

1. Tear-off. The old roofing comes off. The City’s guidelines tell owners to verify whether removal is required before new roofing goes on, because too much weight can damage structural elements.
2. Deck check. With the wood exposed, rot and decay can be found and repaired, in the sheathing or lath and in the structure. This is where the decking allowance in the contract gets used.
3. Underlayment. The water-resistant layer goes over the deck. On a Fortified roof the deck is sealed.
4. Edges and flashing. Drip edge, valley metal and the flashing at chimneys, walls and vents. The guidelines advise flashing with a life span similar to or longer than the roofing.
5. The covering. Shingles, metal, tile or slate, fastened for wind. The guidelines call for appropriate fasteners for New Orleans’ hurricane-strength winds.
6. Ridge, vents and gutters. Ridge tiles are reset, vents fitted, and gutters and downspouts fastened securely.
7. Cleanup and close-out. Debris is removed, the final photos are uploaded and the certificate follows.

A re-roof is also the moment for work that cannot be done later. The City’s storm guidelines note that some improvements are only possible when a roof is replaced. They list added bracing at roof framing and gable ends, and hurricane straps or clips at the framing connections, and say an architect or engineer may need to be consulted.

What a new roof costs: published figures

Roofer New Orleans sets no prices. For orientation, HomeAdvisor’s roof replacement guide, updated June 17, 2026, gives a national average of $9,609 and says most homeowners spend between $5,903 and $13,377, or $4 to $11 per square foot. By material it lists $3 to $7 per square foot for asphalt shingles, $7 to $13 for metal, $10 to $20 for tile and $15 to $30 for slate or stone.

These are HomeAdvisor’s national figures. They are not New Orleans prices, and only a contractor’s written estimate is a quote. When a local price differs, these are the things behind it.

• Size. The guide prices by the square foot, so the measured roof area sets the base.
• Layers and decking. How much has to come off, and how much wood has to be replaced once it is exposed.
• Material. The published ranges put slate at several times the cost of asphalt shingles per square foot.
• The Fortified standard. A sealed deck, ring-shank nails and upgraded edges are extra work, and the evaluator’s fee is paid by the owner.
• Historic review. Matching materials, resetting ridge tiles and the approval step.
• The permit. The City’s re-roofing permit is $60, or $90 in a historic district.

Compare written estimates for the same scope. The roofing company page shows how to line them up.

If insurance is paying for the roof

If a storm is the reason for the new roof, the claim shapes the budget. The Department of Insurance explains that insurers often pay actual cash value first, with the balance of a replacement cost policy paid when you file receipts. The named storm deductible, typically 2 to 5 percent of the amount the home is covered for, is yours to pay, and state law bars a contractor from paying or waiving it for you without the insurer’s consent. If more damage is found after work begins, the Department’s advice is to document it and file a supplemental claim before it is repaired.

Timing a re-roof around hurricane season

The Atlantic hurricane season runs from June 1 to November 30 and peaks on September 10, with most activity between mid-August and mid-October. Rain is a factor all year: at the National Weather Service’s New Orleans International Airport station June averages 7.62 inches and October, the driest month, 3.70. A roof cannot be left open to the weather, so ask the contractor how much of the roof is opened at a time and how it is covered overnight. Allow for the calendar too. The permit takes 2 to 4 days, historic review takes longer, and a grant project has to be approved before any work starts.

The license a replacement needs

Under Louisiana law, residential roof work with a project value of $7,500 or more can only be quoted and performed by a contractor holding the Residential Roofing or Residential Construction classification. A full replacement will often pass that figure: the national average HomeAdvisor publishes is $9,609. The roofing contractor page explains the rule and how to look a contractor up. For a grant project, confirm as well that the contractor is on the Fortify Homes Program’s list of approved contractors. The roofers page explains which roofers suit which material.
