Commercial Roof Coating in Kenner, LA

Big Easy Roofing coats commercial roofs across Kenner and east bank Jefferson Parish. A protective coating over a sound existing covering is usually maintenance under IBC Section 1512.2.1(4), and the permit and warranty positions follow from that classification. Where a scope grows to include the covering underneath, the classification changes; the line is a code question, and it is confirmed with the Kenner Permitting Office rather than assumed.

Kenner commercial roof coating at a glance

A commercial roof coating is a liquid film applied over a covering that stays in place. IBC Section 1512.2.1(4) permits protective coating applications over listed existing roof systems without tear-off, and that is the direct hook for treating a coating scope as maintenance. Whether a permit is required is confirmed with the Kenner Permitting Office.

The code classification

Protective coating, not covering replacement

IBC Chapter 15 defines reroofing as recovering or replacing an existing covering. Section 1509 sets requirements for roof coatings themselves; Section 1512.2.1(4) permits protective coating applications over listed existing roof systems without tear-off. Neither treats a protective coating as a replacement of the covering. NRCA carries the same practical distinction.

When it changes

The scope crosses the covering line

A coating job crosses into a recover or a replacement when the existing covering is being added to or taken off rather than coated over. A recover adds a new covering layer over the existing one, and the two-or-more-existing-coverings rule that closes the recover route sits on the commercial roof replacement page. A replacement removes existing material and installs new. Localised repair of seams or penetrations can stay inside repair. Where the scope moves out of coating and into recover or replacement, the Permitting Office decides the permit.

Which office covers you

Kenner Permitting Office

Kenner has one office at file for commercial roofing scopes: the Permitting Office at the City of Kenner Inspection and Code Enforcement Department, 1926 18th Street, Kenner LA 70062. Phone (504) 468-4062 option 1, Monday to Friday 8:30 AM to 4:30 PM. Intake is by email to kennerpermits@kenner.la.us or drop-off at the 18th Street office. Kenner does not use MyGovernmentOnline; the MGO cities in this area are Metairie, Gretna, Harahan and Baton Rouge.

How the fee is set

Cost varies, named at file

Kenner publishes no commercial roofing coating line item this page can quote. The Permits and Licensing page (kenner.la.us/249) states only "Cost varies" for the applications it lists, and the applicable fee is obtained from the Permitting Office at intake rather than presented here.

What decides the scope

The condition of the covering

A coating cannot dry saturated insulation, cannot bridge a covering that has failed at the seams, and does not renew the covering warranty. Wet insulation or a covering that has failed below the level of a repair are findings that require a revised repair or replacement scope; the resulting work determines the permit classification. The survey settles this before a scope is priced, and any wet insulation finding runs through the commercial inspections page.

Warranty is written on the specification

And it varies by manufacturer

A coating manufacturer issues its material warranty against the specified system, dry film and preparation, and sometimes against an approved applicator. It does not automatically renew the covering manufacturer's warranty on the covering underneath, and manufacturer authorisation, existing-warranty implications and the warranty terms actually offered are confirmed in writing for the specific job.

A coating and a reroof answer different questions. A reroof recovers or replaces the roof covering, is priced against area and assembly, and generates a permit file and inspections under Louisiana R.S. 37:3737(I). A protective coating sits on top of a covering that stays in place, is priced against substrate condition and film thickness, and IBC Section 1512.2.1(4) permits it over listed existing systems without tear-off. On the classification the code and NRCA agree: a protective coating is not a covering, so it is not reroofing.

That distinction shapes what this page owns. Not the arithmetic of mils and gallons, and not the chemistry of silicone against acrylic, which sits on the commercial elastomeric coatings page. What sits here is the code position: where a coating scope is defensibly priced as maintenance, where it crosses into a recover or a replacement, and how the documents the job ends with follow from that classification. Kenner's single office at file, the Permitting Office at 1926 18th Street, is the party that confirms the classification when the scope raises the question, and the intake is email-first through kennerpermits@kenner.la.us rather than an online portal.

Four scopes and how the code classifies each

The same roof can be worked at four different levels. The table sets each against its IBC classification and against what the coating warranty attaches to, so a scope can be read against the code before it is priced. Permit applicability is confirmed with the Kenner Permitting Office rather than assumed.

The four rows use IBC terminology deliberately: a recover ADDS a new covering layer over the existing one; a replacement REMOVES the existing covering and installs new. A protective coating is neither. The Permitting Office decides the permit on a specific scope, and we settle the classification and the permit position at the survey. Call (504) 800-8196 to have the roof surveyed and the code position confirmed before anything is priced.

The code line, and where a scope crosses it

A protective coating stays on one side of the reroofing rule; a recover or a replacement stays on the other. Between them sits a narrow band where the classification depends on what the survey finds, and where the permit position is confirmed with the Kenner Permitting Office rather than assumed.

What the code covers

La. R.S. 37:3737(I)

Louisiana Act 239 of 2025, recodified by Act 881 of 2026 in Title 37, requires any parish or municipality issuing construction permits to permit and inspect roof construction and reroofing. Subsection (I)(1) routes buildings other than one- and two-family dwellings to International Building Code Chapter 15, adopted with Louisiana amendments through the Louisiana State Uniform Construction Code Council.

The coating provision

IBC Section 1512.2.1(4)

IBC 2021 Section 1512.2.1(4) permits protective coating applications over listed existing roof systems without tear-off. That is the code provision this page rests on: a protective coating over a sound covering is permitted as a coating application rather than a recover or a covering replacement. Kenner names IBC 2021 among the adopted editions on the Permits and Licensing page.

Which office covers you

Kenner Permitting Office

The Permitting Office at the City of Kenner Inspection and Code Enforcement Department, 1926 18th Street, Kenner LA 70062, phone (504) 468-4062 option 1, hours Monday to Friday 8:30 AM to 4:30 PM. Intake is by email to kennerpermits@kenner.la.us or drop-off at the 18th Street office. A coating scope that stays inside a coating application normally does not engage a reroofing permit, confirmed with the Permitting Office at intake.

What the building official may accept

R.S. 37:3737(H)

Where a scope does turn into a recover or a replacement and a permit is pulled, the statute allows a building official to accept location-verified geotagged photographs or video for the inspection. Whether that route is used on a given job is the official's call rather than a promise the scope can make.

The tipping-point signs

Three findings at survey typically move a coating scope out of a coating application and into a repair or a covering replacement. Insulation that is wet under any part of the existing covering, which a coating cannot fix and which reduces the coating's film life. Seams or laps that are open widely enough that a coating cannot bridge them, which is normally answered by patching the covering rather than by relying on the film. And a covering that has delaminated or lost its surface below the level of a repair, which is a covering-replacement question rather than a coating one.

Any of the three requires a revised repair or replacement scope; wet or unsuitable materials must be addressed before any coating or recover is specified. The resulting work determines the permit classification, and the classification is confirmed with the Permitting Office at intake before the scope is priced. A wet insulation zone runs through the commercial roof inspections page for the moisture survey that quantifies it.

The documents each version ends with

A coating application produces a coating manufacturer warranty against the specified system, dry film and preparation, plus a scope of work naming the product and the survey findings the coating was applied over. Whether the underlying covering warranty is affected is a matter the covering manufacturer decides against its own terms, and it is confirmed in writing rather than assumed.

A recover or a replacement with a coating on top adds a permit file with its inspection record. The manufacturer system warranty on the recover or replacement itself is priced and specified on the commercial re-roofing page. Ask for every document that applies to the scope at project close, because what applies varies with the scope: a coating application ends with fewer documents than a recover or a replacement does.

Coating over an occupied Kenner commercial building

Two things shape how a coating job is scheduled here, and neither is about the product. Where the building keeps operating through the work, the sequence protects the interior while the coating is going down. And the coating itself has to develop its rain resistance and full cure to its datasheet properties before weather reaches it.

Cure windows against a Gulf coast forecast

Application conditions, rain resistance and full cure follow the selected product's datasheet. Whether the film cures by giving up carrier to the air, by reaction, or by a combination, is a product property; what applies on every coating is that the datasheet governs. Rain on a film that has not reached rain resistance can wash it, and the roof does not show afterwards which part of the film was compromised.

So the schedule is built around forecast windows and daily stopping lines rather than against a fixed date. Louis Armstrong New Orleans International Airport, which sits inside the Kenner city limits, reports about 63.35 inches of annual rainfall per the 1991 to 2020 NWS normals, which is why weather windows matter on scheduling here, and why a schedule that ignores the forecast is buying a risk it has not priced.

Rooftop equipment and tenants stay live

On a commercial building with rooftop equipment running through business hours, the coating runs around that equipment rather than through it: primer and coating step around live curbs, flashings and drains, and any dust or overspray is contained against the intakes rather than left to sort itself. Tenants underneath usually continue trading, so the sequence protects the interior at the same time as the roof.

Documentation while the roof is still open

A coating job records itself as it goes on. Wet film readings are taken as the coating is applied, so the finished dry film can be documented against the specification rather than assumed. That record travels with the manufacturer warranty and is the reason the warranty rides on the actual thickness rather than on a nominal one. It also becomes the baseline a future re-coat is scheduled against.

Big Easy Roofing Process

A commercial coating is classified before it is priced, because the classification decides whether the scope is a coating application, a repair, a recover or a replacement. Four steps, and the first two are the code question rather than the product question.

01

Survey the covering, insulation and seams

The roof is walked and the covering, seams, penetrations and drainage are recorded. Insulation is sampled where the survey suggests it is worth doing. What the survey finds decides which classification the scope belongs on, so the walk precedes any product name.

02

Confirm the classification with the Permitting Office

The classification (coating application, repair, recover, replacement) is confirmed with the Kenner Permitting Office on (504) 468-4062 option 1 where the survey raises the question, and the intake path is by email to kennerpermits@kenner.la.us or drop-off at 1926 18th Street. That is a call before the pails are ordered, not after.

03

Written specification and price

The scope names the product, the specified dry film, the preparation, the classification the scope is being priced under, and any office confirmation that has been done. Price is fixed to that scope rather than to a plan. Manufacturer authorisation and warranty terms are confirmed in writing before work starts.

04

Apply, document, hand over the paperwork

The film is applied against the specification and the wet rate measured as it goes on. At close, you receive every document that applies to the scope actually delivered: the coating manufacturer warranty, the scope of work naming what the coating was applied over, and any permit file and covering manufacturer warranty where a recover or a replacement was part of the scope. Call (504) 800-8196 to book the survey.
