If the fix fails

Where Big Easy Roofing detects and repairs a leak and it recurs within 30 days, we return at no charge to re detect and re seal.

Every figure on this page is an estimate, not a quote, and is subject to Big Easy Roofing sign off. Cost and timescale depend on size, pitch, access, weather, materials and whatever is found once work starts, so call Big Easy Roofing on (504) 800-8196 and we will come out and give you an estimate for your own roof.

A ceiling stain in a Metairie home almost never sits directly under the roof entry point. Water runs along the underside of the decking, follows the rafters and finds a joint to drop through, so the point on the ceiling and the source on the roof can be several feet apart or, on a two storey home, several rooms apart. Guessing costs a homeowner two things: the wrong repair and the returning stain that follows it.

Big Easy Roofing runs an infrared scan on the deck, cross checks with a pinless moisture meter, and where the water path is not obvious, injects a food safe tracer dye that shows up under UV from below. The result is a photograph pack that names the true entry point before any shingle comes off the roof. Detection is diagnostic, not construction.

Common Metairie leak sources and detection method

Six leak sources cover the majority of Metairie roof leak detection visits. Each has a fingerprint the detection kit picks up, a typical path the water takes, and a typical scope for the repair that follows. The detection visit names the source before the repair is priced, so the homeowner knows what they are paying to fix.

Leak sourceHow we find itWater pathTypical repair scope
Cracked pipe bootVisual + IR at the boot baseDown the pipe, into the ceiling near a bath or kitchenBoot replacement, re shingle surround
Failed step flashingVisual + moisture meter on the wall insideDown the wall cavity, stain at the top of a bedroom wallStrip and re seat flashing, matching sealant

Detection method and repair scope depend on the specific defect and are confirmed in the written report. Call (504) 800-8196 to book a Metairie leak detection visit.

Permits, licence and insurance for a Metairie leak detection

A leak detection visit is diagnostic, not construction, so Jefferson Parish requires no permit for the visit itself. The Louisiana Department of Insurance treats an active leak as an event you must mitigate to keep the underlying loss covered, and a documented detection report is the record most Louisiana carriers accept as proof of prompt action.

No permit for detection

Diagnostic visit

Jefferson Parish does not require a permit for a diagnostic leak detection visit on a one or two family home in Metairie. The parish permit rule kicks in only when the follow up repair scope crosses the construction threshold.

Duty to mitigate

LDI rule

The Louisiana Department of Insurance requires policyholders to take reasonable steps to prevent further damage after a covered loss. A documented leak detection report is one of the strongest records that step was taken promptly, and the pack goes to the adjuster on request.

Repair permit rule

$50 flat

Where the leak detection uncovers a defect large enough that the repair replaces 50 percent or more of the covering, Jefferson Parish charges a flat $50 residential re roofing permit fee via MGO Connect. The permit is pulled by us and itemised in the scope.

Louisiana licence

$7,500 or more

Under La. R.S. 37:2156.4, residential roof work priced at $7,500 or more requires a Louisiana State Licensing Board for Contractors licence from 1 January 2026. Big Easy Roofing holds the residential licence for any repair scope the detection uncovers.

Why infrared works on a Metairie deck

Wet decking holds heat differently to dry decking, and an infrared camera reads that temperature signature as a visible cold or hot patch depending on the time of day. Late afternoon on a Metairie summer roof, when the deck has heated all day, is the highest contrast window and the easiest time to find hidden moisture.

The IR image is only a suspect zone, not proof. A pinless moisture meter reading is what confirms the finding on the deck before any tarp goes on.

When detection turns into a full replacement

A detection visit occasionally uncovers deck rot or underlayment failure across more than half of a slope, which turns the repair into a full replacement. The Jefferson Parish permit is pulled, the flat $50 fee is itemised, and the FORTIFIED upgrade path is worth pricing against the standard replacement.

Any change on that scale is written into an amended scope and signed before the crew continues on your Metairie roof. Nothing is decided on the ladder.

The tells of a hidden leak on a Metairie roof

A hidden leak on a Metairie roof shows itself indoors long before the roof looks damaged from the outside. Three interior tells cover most calls, and each maps to a different type of roof defect the detection kit is designed to find. Catching the tell early is the difference between a $400 boot replacement and a $4,000 ceiling and insulation rebuild.

Ceiling stain that appears days after a rain

Water pools inside the deck cavity and only reaches the ceiling after the storm has passed. The stain is usually a light brown ring in the corner of a bedroom or hallway, and it is often several feet from the actual roof entry point because the water has followed the rafter down.

Infrared and moisture meter across the deck above the stained ceiling are what actually locate the source. A visual check from the roof surface alone misses it.

Musty smell in the attic after Gulf humidity

A slow leak that dries between rain events leaves a musty smell in the attic long before it produces a visible ceiling stain. Metairie's summer humidity keeps the deck damp enough that the smell is often the first sign, and it usually traces back to a failed pipe boot or a lifted step flashing at a wall.

Moisture meter readings across the deck sheathing pick up damp zones the eye cannot see, and the report names the entry point before any repair scope is priced.

Blistered paint or drywall bubble at a wall

A stain on a bedroom or bathroom wall near the roofline usually points to a step flashing failure rather than a shingle defect. Water sheets down the exterior wall behind the siding, finds the wall cavity through the flashing, and the drywall paint blisters at the top of the interior wall.

Dye trace and moisture meter on the wall cavity confirm the source. A shingle repair in that scenario fixes nothing, because the shingles were not the entry point.

Big Easy Roofing Detection Process

How long does a Metairie roof leak detection visit take

Most Metairie leak detection visits take one to three hours on site. The visit covers an infrared scan of the deck, moisture meter readings on any suspect zone, and where needed a tracer dye test. Larger homes with multiple suspect zones can take up to a full day.

How much does roof leak detection cost in Metairie

Estimated ranges. A standalone leak detection visit runs $250 to $450 depending on roof size and number of suspect zones. When the follow up repair is booked with Big Easy Roofing, the detection visit is normally free or credited against the repair scope. Emergency tarp add on runs $250 to $500.

Do I need a Jefferson Parish permit for a leak detection visit

No. A leak detection visit is diagnostic, not construction, so Jefferson Parish does not require a permit for the visit itself. The parish permit rule kicks in only if the follow up repair scope crosses the 50 percent threshold for a residential re roofing permit.

Does homeowners insurance cover roof leak detection in Louisiana

In most cases the detection visit itself is not directly reimbursed, but the report is used to support the underlying claim. The Louisiana Department of Insurance requires policyholders to take reasonable steps to prevent further damage after a covered loss, and a documented detection report is one of the strongest records of that action.

What detection methods does Big Easy Roofing use

Three methods, layered. Infrared thermal imaging locates trapped moisture in the deck by temperature contrast. A pinless moisture meter confirms the finding without cutting into the ceiling or the roof. Food safe tracer dye is injected where the water path is not obvious, and shows up under UV from below to prove the entry point.

Can you find a leak I have not been able to trace myself

Usually yes. Homeowners typically look for the leak directly above the ceiling stain, and the water is almost never entering at that point. Big Easy Roofing runs infrared and moisture readings across the full deck cavity, which is the only reliable way to trace a Metairie leak back through the rafters to the true entry point.

What if the leak is a slow leak that only appears sometimes

Slow leaks are the hardest to trace by visual inspection because there is nothing dripping when the roofer arrives. Infrared and moisture meter readings still find the affected zone, because the deck holds residual moisture from previous rain events for days. Book the detection visit as soon as possible after the last event, while the moisture signature is still fresh.

What happens if the detection finds no leak

The visit ends with a written pack confirming the roof reads dry on infrared and moisture meter, and identifying likely non roof sources for the ceiling stain, such as a bathroom fitting, an HVAC condensate line or plumbing above the stained area. Roughly one in six Metairie leak calls turn out not to be roof leaks at all.

Do you provide leak detection in Old Metairie, Bucktown and the lakeside neighbourhoods

Yes. Big Easy Roofing runs leak detection visits across all of Metairie, including Old Metairie, Bucktown, the Lake Vista side, and the neighbourhoods along Veterans and Metairie Road. Coverage extends to Kenner, Harahan, River Ridge and the rest of unincorporated Jefferson Parish.

Do you handle leak detection on commercial flat roofs in Metairie

Yes. Commercial flat and low slope roofs (TPO, modified bitumen, single ply, built up) take a different detection approach that includes a moisture survey of the insulation layer below the membrane. Big Easy Roofing runs commercial leak detection across Metairie and prepares the report for the property manager and, where applicable, their insurance carrier.
