Roof Coating in Kenner, LA

Big Easy Roofing coats low slope roofs across Kenner and east bank Jefferson Parish. A coating buys years on a roof that is still sound underneath. It buys nothing at all on one that is not, so the survey comes before the price.

Kenner roof coating at a glance

A roof coating is a liquid applied membrane rolled or sprayed over an existing low slope roof. It buys years on a roof that is still sound, and it does nothing for one that is not, which is why the substrate decides whether it is worth doing at all.

Estimated applied

$2 to $6 per square foot

Driven by the coating system, how many coats, the condition of the substrate and how much preparation and detailing the roof needs before anything is applied. Every figure here is an estimate, not a quote.

Typical coating life

10 to 15 years

On a sound, correctly prepared substrate with the detailing done properly. A coating over a roof that was already failing does not reach the bottom of that range, which is the whole reason the survey comes first.

It is not a leak repair

Fix first, then coat

A coating is not a way of stopping an active leak. Water already in the build up stays in it, and sealing the surface over a wet roof traps it. Any leak is traced and repaired as its own scope before a coating is priced.

It is not for shingles

Low slope roofs

Coatings belong on low slope membranes and metal. Painting a coating onto an asphalt shingle roof is not a recognised way of extending it and can interfere with how the covering sheds water and dries.

Kenner names its code editions

Nine of them

The City publishes the nine code editions it currently follows, including the existing building code and the energy code, and notes that each carries Louisiana state amendments. A coating is work on a building that already exists rather than new construction, and which of those editions a reviewer applies is the department's call.

Ponding decides a lot

Water that sits

Areas where water stands rather than drains change which coating systems are appropriate and how long any of them last. Where a roof ponds badly the honest answer is often drainage or replacement rather than a coating.

Which roofs a coating suits, and which ones it does not

A coating is a decision about the roof underneath it rather than about the product. These are the substrates it gets proposed for and what actually happens on each. The last column is the one that decides whether the money is well spent.

Every figure and timing on this page is an estimate rather than a quote. Three of these five rows end in advice that is cheaper for you and worth less to us, which is the point of publishing them together.

A coating is work on a building that already exists

A coating is work on a building that already exists rather than a new roof. Kenner publishes the nine code editions its plan reviewers work from, and notes that each one carries amendments from the Louisiana State Uniform Construction Code Council. Which of them applies to a given job is the department's call.

The City lists what it follows

Nine editions, by name

The Kenner Permits and Licensing page names the nine codes the City currently follows, among them the International Existing Building Code 2021 and the International Energy Conservation Code 2021. Which of them a plan reviewer would apply to a particular coating job is a question for the department, not something we settle here.

The state amends all of them

LSUCCC

The same page states that each of those codes contains amendments per the Louisiana State Uniform Construction Code Council, and links the LSUCCC codes page for the complete list. So the edition number alone is not the whole answer, and we do not pretend otherwise.

Somebody at the City reads the plans

Not just a filing clerk

The department states that its personnel review commercial and residential plans to insure compliance with the City's building code and other related regulations. That is a named reviewer with a named rulebook, which is more than most coating conversations have.

What we will not tell you it says

We have not read it

We are not going to quote what the existing building code or the energy code requires for a coating, because we have not read those editions and the state amendments sit on top of them. Whether a particular job needs a permit goes to the department on (504) 468-4062, option 1.

Why naming the rulebook is worth something

Most coating sales conversations are product conversations. A manufacturer name, a warranty length, a number of coats. None of that tells you what standard the work is held to, or who checks it.

Kenner publishing its adopted editions means the question "what is this judged against" has a real answer, and it means a scope can be written against something rather than against a brochure.

What decides it is still the roof underneath

The code list tells you the rulebook. It does not tell you whether your roof should be coated at all, and that answer comes from the survey: the state of the membrane or the metal, the seams and penetrations, and whether water drains or sits.

Where the substrate has gone, a coating is money spent on a roof that needs replacing, so a roof inspection record comes first and a roof replacement is the honest scope if that is what it shows.

What this climate does to a coated roof

Kenner sits on the east bank of Jefferson Parish, hot and humid for most of the year with heavy rain arriving fast. That combination is hard on a low slope roof and it is hard on the coating over it, in two different ways.

Water that arrives faster than it leaves

Heavy rainfall over a short period finds every low spot on a flat roof. Where the falls are shallow or a drain is partly blocked, water stands after the rain has stopped rather than running off.

Standing water is the single biggest predictor of how long a coating lasts here, which is why the survey records where it sits rather than only what the surface looks like.

Sun and heat work on the surface all year

Sustained sun is what a reflective coating is for, and it is also what ages the coating itself. Systems differ in how they handle that, and the honest position is that the roof and its exposure decide the system rather than the other way round.

A coating that is recoated on schedule keeps working. One that is left until it has failed is a strip and start again, which costs considerably more.

Detailing is where coatings fail

Not in the open field, but at the seams, the upstands, the drains and anything that penetrates the roof. Those are the same places a membrane fails, and a coating does not change that.

So the preparation and the detailing are most of the work and most of the value. Keeping the roof on a maintenance schedule afterwards is what protects it, and any defect found on the way is scoped as a roof repair rather than coated over.

Big Easy Roofing Process

Four steps, and the first one can end with us telling you not to coat it. That is a real outcome here rather than a disclaimer.

01

01 Survey the substrate and where water sits

The membrane or the metal, the seams, the upstands, the penetrations and the drainage, recorded with photographs so the decision is made on evidence.

02

02 Say plainly whether a coating is the right answer

Sound and draining is a coating. Actively leaking, badly ponding or simply worn out is a repair, a drainage fix or a replacement, and we will say which.

03

03 Write the system, the preparation and the value

Which coating system and how many coats, what preparation and detailing is included, and the figure, with anything found on the survey named before the work starts.

04

04 Prepare, detail, then coat

Clean down, seams and penetrations detailed, then the coating applied to the specified thickness, with the finished roof photographed for the record.

Kenner Roof Coating FAQs

Which roofs a coating actually suits, what the City of Kenner names as its code editions, and when the honest answer is not to coat it.

Topic

Question not here?

Ask us whether your Kenner roof is worth coating. No charge to ask.

Call (504) 800-8196
Will a coating stop my roof leaking

No, and it is not meant to. A coating goes onto a roof that is already watertight, to extend it. Applying one over an active leak seals water into the build up. The leak gets traced and repaired as its own scope first, and only then is a coating worth pricing.

Can you coat an asphalt shingle roof

No. Coatings belong on low slope membranes and on metal. Painting a coating onto shingles is not a recognised way of extending a shingle roof and can interfere with how the covering sheds water and dries out.

My flat roof holds water after rain, can it still be coated

Sometimes, but it changes the answer. Standing water is the biggest single influence on how long a coating lasts here, so where a roof ponds across large areas the honest recommendation is usually drainage work or replacement rather than a coating.

What code does Kenner judge this work against

The City publishes the nine code editions it currently follows, including the International Existing Building Code 2021 and the International Energy Conservation Code 2021, and states that each contains amendments per the Louisiana State Uniform Construction Code Council. We will not tell you what those editions say about coatings, because we have not read them.

Does a roof coating need a permit in Kenner

Ask the department rather than a roofer. The City publishes nothing saying a coating does or does not need one, and its permitting office takes that question on (504) 468-4062, option 1. We ask rather than assume, and we put the scope and the value in writing first so there is something to ask about.

What does roof coating cost in Kenner

Estimated at $2 to $6 per square foot applied, driven by the system, the number of coats, the condition of the substrate and how much preparation and detailing is needed. Every figure here is an estimate and a written price follows the survey.

How long does a roof coating last

Typically 10 to 15 years on a sound, properly prepared substrate with the detailing done correctly. A coating put over a roof that was already failing does not reach the bottom of that range, which is why the survey decides whether to coat at all.

Is a coating cheaper than a new roof

On a sound roof, yes, and that is the case for doing it. On a roof that has reached the end, a coating is money spent twice, because the replacement still has to happen and now there is a coating to deal with as well. The survey is what tells the two apart.

Find out whether your roof is worth coating before anybody prices one

A coating buys years on a roof that is still sound and nothing at all on one that is not, so we survey the substrate, the seams and the drainage and record it with photographs first. If the answer is that a coating is the wrong spend, you will hear that. Kenner publishes the code editions its reviewers work from, so the scope is written against a named rulebook rather than a brochure. If you would rather start in writing, tell us what the job involves and we will come back with an estimate.
