Do I need a permit for a commercial reroof in Kenner?

Yes. Louisiana requires permitting and inspection of roof construction and reroofing of commercial structures for projects beginning on or after 1 August 2025, and for buildings other than one and two family dwellings the reference is International Building Code Chapter 15, at La. R.S. 37:3737(I)(1).

What does the commercial roofing permit cost in Kenner?

The City of Kenner Permits page states "Cost varies" against every project type on its schedule. It is a refusal to publish a scale rather than a low or a high figure, and the amount is confirmed by the Permitting Office on (504) 468-4062 option 1. That is the published position as read in September 2026.

How is the application filed?

Applications are emailed to kennerpermits@kenner.la.us or dropped off at 1926 18th Street. Kenner does not use MyGovernmentOnline, so there is no online submission. The intake is Monday to Friday 8:30 AM to 4:30 PM through the Permitting Office.

Does my roofer need a state licence for commercial work?

Commercial roofing has its own licence classification, which is separate from the residential roofing classification that applies to houses. Ask for the Louisiana state licence number and its expiry date and verify the number and the classification directly with the State Licensing Board, because the classification matters as much as the number.

Should the existing roof be torn off or recovered?

It is decided on the deck and by the code. International Building Code Chapter 15 Section 1512 bars a recover where two or more existing coverings are already in place, so a recover is only available on a roof carrying one covering that is otherwise sound. Wet insulation under a new membrane fails the new roof and voids most manufacturer warranties.

Can the work happen while the building stays open?

Usually. The roof comes off in sections small enough to be stripped, dried in and made watertight the same day, and areas over plant or stock are sequenced deliberately. It is slower than a vacant building, which is a programme consideration rather than a specification one.

Does the manufacturer warranty cover everything?

No, and it is a separate record from the permit file. Enhanced system warranties commonly require an approved installer and a manufacturer review before they are issued, while basic material warranties often do not, and every one carries its own conditions. Requirements vary by manufacturer and warranty type, so the terms are read before the system is chosen rather than after. Neither document substitutes for the other.

What usually sets the programme?

The rooftop penetrations and the weather windows, rather than the field of the roof. Units, ducts and drains take longer than open area, and on an occupied building the amount of deck that can be opened at once is limited by what can be closed again the same day.

Is the Rivertown Historic District Design Commission involved?

Only for a building inside the Rivertown Historic District boundary along the Mississippi River. A commercial address inside that boundary confirms the position with the Planning Department on (504) 468-7240 before a covering material or profile is ordered. Outside that district the HDDC has no role.

Commercial Roof Replacement in Kenner, LA

Big Easy Roofing replaces low slope commercial roofs across Kenner and east bank Jefferson Parish. On a commercial roof the membrane is the part everyone quotes and the insulation under it is where the money and the risk actually sit, so the first thing we settle is whether the existing assembly comes off or stays.

Kenner commercial roof replacement at a glance

A commercial reroof in Kenner runs on two decisions and two documents. Whether the existing assembly is stripped or recovered decides the assembly. Which office covers the building decides the paperwork, and in Kenner that paperwork is emailed to the Permitting Office rather than filed through MGO the way it is in Metairie, Gretna and Harahan.

The intake is email, not a portal

kennerpermits@kenner.la.us

The City of Kenner Permits page states that applications are emailed to kennerpermits@kenner.la.us or dropped off at 1926 18th Street. Kenner does not use MyGovernmentOnline. Metairie, Gretna, Harahan and Baton Rouge do use it. Hammond takes a City form on paper. Kenner takes the application into a human review inside office hours.

The fee is not published

Cost varies, confirmed at file

The Permits page prints the sentence "Cost varies" against the fee for every project type on its schedule, including commercial work. That is a refusal to publish a scale rather than a low or a high figure. The amount is confirmed by the Permitting Office on (504) 468-4062 option 1.

Which office covers you

City of Kenner, by boundary

Kenner is an incorporated city on the east bank of Jefferson Parish. Inside the city limits the Inspection and Code Enforcement Department at 1926 18th Street permits the work, on (504) 468-4064. Outside them the address sits in unincorporated Jefferson Parish and follows the parish route. A Kenner postal address does not decide which side of the line the building falls on.

Which code applies

IBC Chapter 15

La. R.S. 37:3737(I), introduced by Act 239 of 2025 and recodified by Act 881 of 2026. Subsection (I)(1) routes every building that is not a one or two family dwelling to International Building Code Chapter 15, the roof assemblies chapter, as adopted with Louisiana amendments. The City of Kenner names IBC 2021 among nine adopted editions on its Permits page.

Two records come out of the job

Permit file and warranty file

The permit and its inspections are one record, held by the authority. The membrane manufacturer warranty is a separate record with its own conditions. Enhanced system warranties commonly require an approved installer and a manufacturer review, while basic material warranties often do not, so requirements vary by manufacturer and warranty type. Neither record substitutes for the other.

Ask for the classification on a commercial job

Verify with the Board

Commercial roofing carries its own licence classification, separate from the residential roofing rule that applies to houses. Ask any contractor bidding this work for their Louisiana state licence number and its expiry date, and verify the number and the classification with the State Licensing Board rather than taking it from a letterhead.

This page addresses roofing on buildings treated as nonresidential for licensing and code purposes. Mixed use buildings and residential multifamily need their own classification and code review, because the residential rules run on the character of the structure rather than on what a contract calls the job.

Permit routing on this page is what kenner.la.us/249 publishes in September 2026, not a quote from the office. Commercial roofing itself is priced on area and assembly rather than a published range, so call Big Easy Roofing for a scoped price.

The assemblies we replace and what each one is for

Five systems account for the bulk of low slope commercial roofing. The table sets out what each is suited to and what to watch on it, so a quote can be read against the building and its use rather than against a brand name on the cover sheet.

Assembly	What it suits	Typical service life	What to watch
TPO single ply	Large open roofs where a reflective surface is wanted	20 to 30 years	Seam quality is the whole system, and welded seams are only as good as the day they were run
PVC single ply	Kitchens, plant rooms, grease or chemical exposure	20 to 30 years	Costs more than TPO, which is exactly why it is specified where grease is present
EPDM rubber	Simple roofs where a long track record is wanted	20 to 30 years	A black surface absorbs heat, so it is a poorer fit where cooling load matters
Modified bitumen	Smaller roofs, foot traffic, complex detailing	15 to 25 years	Detailing is its strength and the number of laps is where workmanship shows
Built up roofing	Heavy traffic, long established buildings	20 to 30 years	Weight is the constraint, so the deck and structure decide whether it is even an option

Service life assumes the assembly is drained, insulated and detailed properly. Any of the five will fail early on a roof that ponds, so drainage is settled with the membrane rather than after it.

The permit route here goes through a person

Most places in this region route a commercial roofing application through an online portal. Kenner routes it through an email address and a phone call, and the fee is set by the department rather than by a published scale. A real reviewer reads the scope before the file opens.

Permitting and inspection are compulsory

Statewide since 2025

The State Licensing Board for Contractors states that Act 239 requires permitting and inspection of roof construction and reroofing of residential and commercial structures for any project beginning on or after 1 August 2025. It is carried at La. R.S. 37:3737(I) after Act 881 of 2026 recodified the section.

Inside the city limits

City of Kenner

The Inspection and Code Enforcement Department at 1926 18th Street handles permit intake through the Permitting Office on (504) 468-4062 option 1, Monday to Friday 8:30 AM to 4:30 PM. Applications are emailed to kennerpermits@kenner.la.us or dropped off in person. No online submission is offered.

Outside the city limits

Unincorporated Jefferson Parish

Where the building sits outside the Kenner city limits the address falls under unincorporated Jefferson Parish and follows the parish route. A Kenner postal address covers both areas, so the boundary rather than the address decides the office. This is the same posture as Metairie, which is entirely unincorporated.

Two or more layers already bars a recover

IBC Section 1512

International Building Code Chapter 15 Section 1512 bars a recover where two or more existing roof coverings are already in place. Two is the bar, not the limit. A recover is only available on a roof carrying one existing covering that is otherwise sound. Where a survey shows moisture or a second layer, tear off is the answer even where it is the more expensive one.

Failing to obtain inspections is a violation

Act 422 of 2025

The Board states that Act 422 makes it a violation of the law for a contractor to fail to obtain a permit, to begin work before the permit is issued, to misrepresent the value or scope of work, or to fail to obtain inspections as required by law.

Why the email intake changes the timeline

An application filed by email is read by a person during office hours rather than logged into an online queue. On a straightforward reroof that is faster than it sounds, because a reviewer who can read the scope in one sitting rarely needs several rounds of clarification.

On a phased or complicated commercial job the same channel means the file starts with a conversation rather than a form field. Both sides save time, provided the scope is written before the email is sent rather than sketched inside it.

Why the value stated on the application still matters

The published fee is "Cost varies", not a scale, so the amount is set by the department. The declared value of the work is still the basis of that conversation. Act 422 of 2025 separately makes it a violation for a contractor to misrepresent the value or scope of work, which puts an accurate figure on both sides of the same requirement.

That is a reason to have the scope written and priced before the application is filed rather than after, and it is the same discipline that keeps the permit file and the manufacturer warranty file agreeing with each other later.

Replacing a roof over a building still in use

Commercial reroofs in Kenner frequently happen over an occupied building, which changes the sequence more than it changes the specification. Three constraints do the work, and all three are programme decisions taken before the first fastener rather than problems solved on site.

The building keeps operating, so the roof comes off in sections

Work is broken into areas that can be stripped, dried in and made watertight within the same day, rather than opening more deck than the weather allows. That is slower than a vacant building and it is the only way to protect what is underneath.

It also decides where the tear off starts. Areas over plant, stock or anything that cannot be moved are sequenced deliberately, not left until last by default.

Rooftop plant and penetrations are the real programme

Units, ducts, conduit and drains all have to be lifted, isolated or worked around, and each one is a detail that will leak if it is reinstated badly. Penetrations frequently take longer than the field on a commercial roof.

Where equipment has to be shut down or lifted, that is scheduled with the building rather than assumed, because a crane slot and a tenant notice are not things that can be arranged on the morning.

Tear off or recover is decided on the deck, not the budget

A recover leaves the existing assembly in place and is quicker and cheaper, but it is only available under IBC Section 1512 where the existing roof carries one covering that is otherwise sound.

Wet insulation left under a new membrane fails the new roof and voids most manufacturer warranties. Where a survey shows moisture, the tear off is the answer even though it is the more expensive one.

Big Easy Roofing Process

Four steps. The first two are survey and paperwork, because on a commercial building the deck condition decides the assembly and the declared value goes to the department rather than into a fee formula.

01 Survey the deck and the existing assembly

Moisture, insulation condition, number of existing layers and drainage. This decides tear off or recover before anything is priced, and the answer is settled by IBC Section 1512 as much as by the survey.

02 Establish the office and file the application

City of Kenner or unincorporated Jefferson Parish, application emailed to the Permitting Office or dropped off at 1926 18th Street with the value and scope stated accurately.

03 Specify the assembly with its insulation and drainage

Membrane, insulation, fastening and falls specified together, with the manufacturer warranty conditions known before the system is chosen rather than after.

04 Phase the work and hand over both records

Sections stripped and dried in the same day, then the permit file with its inspections and the manufacturer warranty file handed over together.
