Roof Repair in New Orleans, LA: Leaks, Storm Damage and Historic Roofs

Water finds the weak point. In New Orleans it gets plenty of chances, with 60 inches of rain or more in a normal year and a hurricane season that runs for six months. A slipped slate, a cracked ridge tile or a few lifted shingles can sit unnoticed until the next hard rain puts a stain on the ceiling.

This page explains roof repair in New Orleans, Louisiana: why roofs here leak, what to do in the first days after storm damage, where leaks start, how each kind of roof is repaired, when repair stops making sense, which repairs need a permit or historic district approval, what a named cost guide publishes, and what the Department of Insurance tells policyholders about a roof claim. The rules and figures come from the City of New Orleans, the Louisiana Department of Insurance, the U.S. Army Corps of Engineers, the National Weather Service and the National Hurricane Center.

Roofer New Orleans is a referral service, not a roofing contractor. We connect you with an independent local roofing contractor, and that contractor looks at the roof, prices the repair and does the work. The call is free.

Why roofs in New Orleans leak

Start with the volume of water. The National Weather Service’s 1991 to 2020 normals show 60.12 inches of precipitation a year at New Orleans Lakefront Airport, inside the city, and 63.35 inches at New Orleans International Airport in Kenner, west of the city. At the International Airport station June brings 7.62 inches, July 6.79 and August 6.91. Even the driest month there, October, brings 3.70 inches, so a roof here has no dry season.

Wind does the sudden damage. The City’s storm preparedness guidelines say some of the greatest damage to a building in a tropical storm or hurricane comes from high winds that compromise the roof by uplift, taking off the whole roof or components such as slates. The National Hurricane Center’s wind scale says that even a Category 1 storm, with winds of 74 to 95 mph, could damage the roof and shingles of a well-constructed frame home.

The slow causes are less dramatic. The City’s roofing guidelines list them material by material: fasteners that loosen or corrode, asphalt shingles that curl, lose their mineral coating or turn brittle, moss on slopes that stay damp, and tree limbs that crack tile. On a flat roof the usual trouble is standing water and poor drainage.

First steps after storm damage

The Louisiana Department of Insurance set out these steps for policyholders after Hurricane Francine in 2024.

1. Photograph first. Before you begin cleanup, take pictures or video of the damage inside and outside the house.
2. Stop further damage. Make temporary repairs to prevent more loss, such as placing plastic tarps over holes in the roof. Keep receipts for materials and a record of the repairs for the adjuster.
3. Keep what was damaged. You can pull wet items out of the house to prevent mold, but do not throw anything away until an adjuster has seen it.
4. Call your insurer. Contact your agent or company as soon as possible, and find out how long you have to file a claim.
5. Wait on permanent repairs. Do not begin permanent repairs until your insurance adjuster has told you to.

A roofer’s part in those first days is the temporary work and the record: a tarp or a patch, photos of the damage and a written description of what failed. The permanent repair follows the adjuster’s visit. The Department says an adjuster should be sent out within 30 days of a claim being filed in a catastrophe.

Blue roofs and who qualifies

Operation Blue Roof is managed by the U.S. Army Corps of Engineers for the Federal Emergency Management Agency. When FEMA assigns the mission after a disaster, at the request of the affected state, the program covers damaged roofs with fiber-reinforced sheeting until permanent repairs can be arranged, at no cost to the homeowner. It does not run after every storm. The Corps says on its Blue Roof page whether a mission is active.

The Corps’ conditions matter in New Orleans. The home must be a primary residence with no more than 50 percent of the roof framing damaged, and the roof must be standard shingles or a similar material that a tarp can be nailed to. Metal roofs and mobile homes are considered case by case. Contractors cannot cover roofs made of materials such as slate, asbestos or clay tile, so the owner of one of those roofs should plan on a roofer’s temporary repair instead.

Where roof leaks start

The Vieux Carre Commission’s roofing guidelines describe flashing as thin sheet metal formed to keep water out at a joint, an intersection or a change of pitch. It is installed around chimneys, parapets, dormer windows, roof valleys and vents, and where porches, galleries and additions meet the building. The guidelines add that flashing often fails before the roofing material, leaking indoors, particularly on durable roofs such as slate and tile. Those joints are the first places to look.

The same guidelines suggest a starting point that needs no ladder: look at the underside of the roof from the attic for signs of moisture or daylight, paying particular attention to roof penetrations such as a chimney. The City’s guidelines for its other historic districts recommend checking the attic after a storm, to catch small leaks early. A roofer will want to know what you found, so note these things before you call.

• When it leaks. In every rain, only in heavy rain, or only when wind drives the rain from one side.
• Where the stain is. Which room, and what stands on the roof above it: a chimney, a vent, a valley, a ridge or a wall.
• What the attic shows. Damp or dark wood, or points of daylight.
• Photos. The stain, the attic and the roof as seen from the ground.

Ask the roofer to photograph the point where the water gets in and to describe it in the written estimate.

Repairs by roof type

The City’s roofing guidelines, written for its historic districts, list the typical local problems for each material and the usual fix.

Roof	Typical problem	Usual repair in the City’s guidelines
Slate	Loose or corroded fasteners, split or cracked slates, missing slates	Reattach or replace the fasteners or fit a slate hanger. Slip sheet metal under a cracked slate, or replace it. Replace missing slates to match the original.
Clay and concrete tile	Loose fasteners, cracked tile, missing tile or ridge pieces	Reattach or replace the fasteners. Fit sheet metal under the tile, or reattach the broken piece with tinted roofing cement. Replace to match, preferably with salvaged tile of the same dimensions.
Asbestos-cement shingles	Splits and punctures, corroded fasteners, missing shingles	Sheet metal under the shingle and a cement grout fill, new fasteners, and non-asbestos shingles that match the originals.
Asphalt shingles	Splits or punctures, moss, missing or damaged shingles	Sheet metal under the shingle and roofing cement. Trim back trees so the roof can dry. Replace shingles to match.
Metal	Worn paint or coating, slipped sheets and open seams, isolated rust or holes	Repaint, refasten or re-solder, and replace the damaged section to match.
Flat and low-slope	Splits, punctures or cracking, standing water or poor drainage	A patch compatible with the roof material, and a check that the roof slopes to its drain and the drain is clear.

Slate and tile: repair first

Slate and tile are the roofs where the guidelines lean hardest toward repair. They note that problems with a slate roof are typically local, because the fasteners and accessories do not last as long as the stone. They add that individual missing or damaged slates can often be replaced, extending the life of the roof and postponing costly replacement. Owners are urged to deal with local problems as they appear, using a qualified slate roofer. The same holds for tile, with one caution: tiles are relatively fragile, so the repair belongs with someone who knows how to cross them without breaking more.

Ridge tiles and flashing

Ridge tiles turn up on slate, terra cotta, asbestos-cement and asphalt roofs alike in New Orleans, either as English-V tiles with mortar between the joints or as overlapping Spanish tiles. The City’s storm advice includes securing ridge tiles, cresting and finials with mortar and repointing chimneys. Flashing is the other usual suspect. The Vieux Carre Commission’s guidelines say a qualified roofer can replace failed flashing without replacing the entire roof, and both commissions advise choosing a metal with a life span similar to or longer than the roofing.

Repair or replace: the 20 percent guide

The City’s guidelines give a working rule for pitched roofs. If over 20 percent of the slates, tiles or shingles on a roof are damaged or missing, replacement might be warranted. Below that, the guidelines point toward repair. For metal the test is condition: general rusting, splitting, pitting, severe buckling or many open seams.

Points toward repair	Points toward replacement
Damage in one area, which the guidelines call a localized problem	Over 20 percent of the slates, tiles or shingles damaged or missing
One failed part: a flashing, a ridge tile, a handful of slates or shingles	Asphalt shingles that have curled, lost their mineral coating or turned brittle
Slate or tile that is still sound, on a roof built to last a century	A metal roof that is generally rusting, splitting, pitted or badly buckled, or has many open seams

Two local rules sit on top of that judgment. Once a job covers 50 percent of the roof on a one or two-family home, the City requires a re-roofing permit. And the state’s Fortify Homes grant program does not fund patching or partial repairs: the entire contiguous roof covering has to be replaced. If a repair is growing toward half the roof, ask for a roof replacement price alongside it.

Does a roof repair need a permit in New Orleans?

Usually not a building permit. The City’s permit guide lists replacing less than 50 percent of the roofing on a one or two-family dwelling as exempt, although a permit can still be required where the work involves hazardous or complex conditions. Roofs over otherwise unenclosed porches, along with their framing, are not exempt.

Historic districts are different. The same guide warns that exempt work may still need approval from the Vieux Carre Commission or the Historic District Landmarks Commission (HDLC). In the HDLC’s full control districts, which include Bywater, Faubourg Marigny, Holy Cross and Algiers Point, the guidelines say all exterior repairs, no matter how minor, are subject to review when they can be seen from a public right-of-way, and that in-kind repairs matching what is there can be approved by staff. Uptown, Mid-City and Parkview are different again: there the HDLC controls demolition only. In the French Quarter a Vieux Carre Commission permit comes before any exterior work. The roofing contractor page lists the districts and explains both processes.

Larger buildings follow other rules. The exemption applies only to one and two-family dwellings, so ask the City’s Department of Safety and Permits, through its contact page, about a repair on a building with three or more units or a business use.

When a repair needs a contractor with the state roofing license

Louisiana’s roofing license rule starts at a project value of $7,500. From that figure up, anyone who quotes or performs roof work on a residential structure must hold the Residential Roofing or Residential Construction classification from the Louisiana State Licensing Board for Contractors. The typical repair range HomeAdvisor publishes sits well below that figure, but a larger repair can pass it. The roofing contractor page explains the rule and how to look a contractor up, which is worth doing whatever the size of the job.

What roof repair costs: published figures

Roofer New Orleans sets no prices, and nobody can price a repair without seeing the roof. What can be given honestly are the figures a named cost guide publishes. The ones below come from HomeAdvisor’s roof repair cost guide as updated on June 19, 2026. It is a general guide built on HomeAdvisor’s own customer surveys. It gives no figure for New Orleans or Louisiana, and none of its figures is a quote.

Repair	HomeAdvisor’s published figure	Source
Roof repair, typical range	$395 to $1,968, average $1,174	HomeAdvisor, June 19, 2026
Asphalt shingle repair	Average $975	HomeAdvisor, June 19, 2026
Tile roof repair	Average $1,000	HomeAdvisor, June 19, 2026
Metal roof repair	Average $1,700	HomeAdvisor, June 19, 2026
Slate roof repair	Average $1,800	HomeAdvisor, June 19, 2026
Leak repair	$360 to $1,550	HomeAdvisor, June 19, 2026
Flashing repair	$200 to $500	HomeAdvisor, June 19, 2026

These are HomeAdvisor’s general figures, not New Orleans prices, and the guide gives wider ranges for leaks and flashing in its text than in its table. Use them to judge whether a quote sits in ordinary territory. When a local quote differs, these are the things to ask the contractor about.

• Material. Slate and tile repairs call for matching stock, and the City’s guidelines prefer salvaged tile of the same dimensions.
• Height and pitch. Ask how a steep slope or a second story changes the setup.
• Access. Ask whether a gallery, a narrow side yard or a neighboring building makes the roof harder to get to.
• What is underneath. Rot under the roofing cannot be seen until it is lifted, so ask for a unit price for replacing decking.
• Historic review. Matching materials and the approval step apply where a commission reviews the roof.

Only a written estimate from a contractor who has seen the roof is a real price.

What the Department of Insurance says about a roof claim

Policies differ, and the insurer decides what is covered. Roofer New Orleans gives no advice on claims and takes no part in them. The Department of Insurance’s guidance to policyholders explains the parts that surprise people.

• The named storm deductible. It is typically 2 to 5 percent of the amount the home is covered for, not a flat sum. In the Department’s example, a home covered for $200,000 with a 5 percent deductible pays the first $10,000 of repairs out of pocket.
• The first check. Insurers often start by paying actual cash value, which is the depreciated value. With a replacement cost policy, the rest is paid when you file receipts showing the repair was made. The Department says cashing the check does not mean you agree with the amount.
• Supplemental claims. If the damage is worse than the first adjustment recorded, or the contractor finds more once work begins, document it before it is repaired and go back to the insurer. The Department says this right is controlled by policy language but is generally available for up to two years.
• Flood is separate. Flood damage is not covered by a homeowners policy. It falls under the National Flood Insurance Program or a separate flood policy.

Two state rules protect the claim. A contractor may not pay, waive or rebate your deductible without the insurer’s consent, and may not interpret your policy or adjust the claim for you. The roofing company page sets out both. For a question about a claim, or to report suspected fraud, go to the Department through its contact page.

Keeping a repaired roof out of trouble

Most of the upkeep the City’s guidelines recommend can be done from the ground or the attic.

• Look in the attic after a storm. The guidelines recommend it as the way to catch small leaks early and limit damage indoors.
• Keep gutters and downspouts clear and securely fastened. The guidelines note that many New Orleans buildings were not designed with gutters, and that adding them can reduce water damage to walls, foundations and piers.
• Trim overhanging limbs that could come down on the roof, and cut back trees that keep a slope from drying.
• Keep gravel and loose items off a flat roof, where wind can lift them.
• Before a storm, seal and protect skylights and roof vents, including gable-end vents.
• Stay off the roof. The guidelines call roofing work potentially dangerous and say it should be left to professionals, and tile is easily broken.

The point about attics holds for the whole roof: a small leak caught early does less damage indoors. If something on this page matches what you are seeing, the next step is to have a roofing contractor look at it and put the findings in writing. The roofers page explains which roofers suit which roof.
