Kenner flashing repair at a glance

Flashing is the metal that carries water across the joint where the roof meets a wall, a chimney, a valley or a pipe. It is a small job that carries a full sized paperwork question, because the City of Kenner says a building permit is necessary on all construction and does not name roof work either way.

It is a joint, not a product

Where two trades meet

Flashing sits between roofing and whatever it abuts, so it gets blamed on the wall, the chimney or the cladding as often as on the roof. That ambiguity is why it goes unrepaired longer than anything else up there.

Estimated flashing repair

$350 to $1,200

Driven by the length of the run, access, and whether the covering has to be lifted to get new metal properly underneath it. Every figure here is an estimate, not a quote.

What Kenner says a permit covers

All construction

The City's Permits and Licensing page says a Building Permit is necessary on all construction, and then illustrates that with pools, portable or prefab buildings, cement work and fences. Those are jobs people assume are too small to permit.

The application asks for the value

Total estimated value

The City's Building Permit Application has a field for the total estimated value of the work and a field for the state licence number. Both are answered from a written scope, which is a reason to have one before anything is opened up.

Sealant alone is a repeat visit

Months, not years

A bead of sealant over a flashing that has lifted, shortened or corroded hides the symptom for a season. In this heat it then moves, cracks and lets water back into the same joint. The detail has to shed water without it.

Sometimes it is not the roof

And we will say so

Where water is getting in through failed masonry, a cracked chimney crown or the cladding above a flashing, new metal will not stop it. That is a different trade and we will tell you rather than sell you roofing for it.

Five small roof jobs, and what each one really involves

Flashing is not one thing. Five details do five different jobs, they fail in different ways, and the correct repair for one is the wrong repair for another. The last column is the part people are rarely told, which is what actually moves the price.

The jobWhat actually gets replacedHow it fails hereWhat moves the value
Pipe boot or collarThe rubber collar, and often the whole boot with itThe collar perishes under sustained sun, sometimes well inside ten yearsThe smallest of these, and still written down before anyone starts
Step flashing along a wallIndividual pieces, woven back into the coveringLifts, or was set too short in the first place, so water gets behind itThe length of the run, more than anything else
Counter flashing into masonryMetal re-let into the mortar joint, not sealed over itWorks its way out of the joint as the building moves through the seasonsWhether masonry work sits beside it, which is a separate trade and a separate quote
Valley metalThe metal along the run, rather than a patch over itWears through where the most water on the roof concentrates, or opens at the seamThe longest runs of the five, so the value climbs fastest
Chimney pan and cricketThe back pan, and the cricket where there is oneWater collects behind the chimney, so the back goes before the sidesWhere a small job most often turns out not to be a small job

Every figure on this page is an estimate rather than a quote. The common thread is that four of these five are repaired by replacing metal, not by adding sealant to metal that has already failed.

A small job and the same permit question

Kenner puts what a building permit covers in one sentence: necessary on all construction, including pools in and above ground, all portable or prefab buildings, cement work and fences. Roof work is not named in that list either way, so a flashing repair is a question for the department rather than an assumption.

What the City actually publishes

All construction

The Kenner Permits and Licensing page says a Building Permit is "Necessary on all construction, including pools in and above ground, all portable or prefab buildings, cement work and fences. Cost varies." Cement work and fences are the tell: this is a City that permits things people assume are too small to permit.

The state rule is written about reroofing

R.S. 37:3737(I)

Louisiana requires any municipality or parish that issues construction permits to permit and inspect roof construction and reroofing. A flashing repair is not obviously a reroof and not obviously outside it, which is exactly why the department gets asked on (504) 468-4062, option 1.

The form asks for the value first

Total estimated value

The City's Building Permit Application carries a field for the total estimated value of the work and a field for the state licence number. That same value is what the Louisiana residential roofing licence threshold at R.S. 37:2156.4 turns on, which the roof repairs page sets out. A flashing repair in the range above sits well under that threshold. A reroof is a different conversation.

And somebody signs for the code

The currently adopted code

The application carries a certification that the construction or reconstruction it is issued for will be in accordance with the currently adopted building code and ordinances governing construction and reconstruction of buildings in the City of Kenner. That is a signature, not a formality.

Why we ask instead of assuming

The cheapest wrong answer in this trade is a roofer deciding on your doorstep that a job is too small to need paperwork. Kenner publishes no roofing fee and no roofing line in its permit list, so nobody can read the answer off the website, including us.

What we do instead is put the scope and the value in writing and take the question to the Permitting Office, which is a phone call. The answer then belongs to the City rather than to whoever wanted the job to be simple.

If you do not know it is the flashing yet

Water shows up a long way from where it gets in, so the joint you can see is not necessarily the one that failed. Leak detection traces it back before anybody prices a repair, and on a Kenner house it also rules out the sources that are not roofing at all.

Where the flashings are sound but ageing, catching them on a schedule costs considerably less than catching them afterwards. That is what maintenance is for, and a roof inspection puts the whole roof on record if more than one detail is failing.

What this climate does to a flashing joint

Kenner sits on the east bank of Jefferson Parish and is hot and humid for most of the year. A flashing joint is two materials that expand and contract at different rates, working against each other every day the sun is out, which here is most of them.

Daily movement is the whole mechanism

Metal against masonry, or metal against a covering, heats and cools at different rates. The joint between them moves a fraction every day, and that movement is what works counter flashing out of a mortar joint and works sealant loose from both faces.

It is also why a repair that depends on adhesion is fighting the building, and a repair that depends on overlap is not.

Sunlight finishes what heat starts

Sealants and boot collars degrade under sustained sun faster than manufacturer test conditions suggest. Pipe boot collars in particular are often the first thing to fail on an otherwise healthy roof here.

That is not a defect in the roof. It is a consumable reaching the end of its life, and treating it as scheduled replacement rather than as a fault is the cheaper way to handle it.

Wind driven rain attacks joints specifically

Rain arriving sideways gets behind details that shed vertical rain perfectly well. That is why a flashing can be watertight for years and then leak in one particular storm.

If your leak only appears in certain weather, say so when you call. It narrows the search considerably and it is the detail people most often leave out.

Big Easy Roofing Process

Four steps. The first decides whether this is a roofing job at all, which is a question worth settling before anybody buys metal.

01

01 Establish that the flashing is the failure

Rather than the masonry, the chimney crown or the cladding above it. New metal under a failed crown does not stop water.

02

02 Identify which detail failed and how

Boot, step, counter, valley or chimney pan. Each fails differently and each has its own correct repair.

03

03 Write the scope and the total estimated value

What metal is being replaced and over what length, with the figure the City application asks for and the state licence threshold turns on, then ask the Permitting Office what paperwork the job needs.

04

04 Rebuild the detail so it sheds water by shape

Metal lapped in the direction water travels, with sealant as a secondary defence rather than as the thing holding the repair together.

Do I need a permit for a flashing repair in Kenner

Ask the department rather than a roofer. The City says a building permit is necessary on all construction and illustrates that with pools, prefab buildings, cement work and fences, without naming roof work either way. Louisiana requires any authority that issues construction permits to permit and inspect reroofing, at R.S. 37:3737(I). The Permitting Office takes that question on (504) 468-4062, option 1.

What does the City permit application actually ask for

Among other things, the total estimated value of the work and the state licence number of the contractor. It also carries a certification that the construction or reconstruction will be in accordance with the currently adopted building code and ordinances of the City of Kenner.

What will a flashing permit cost in Kenner

The City publishes no fee schedule for this and says only that cost varies. A roofer quoting you a specific Kenner permit fee has not taken that figure from anything the City publishes, so the question belongs with the Permitting Office rather than with a contractor.

Why did the flashing start leaking again after it was sealed

Because sealing it treated the symptom rather than the detail. That is the most common repeat repair in this trade. Flashing sheds water by shape, by overlapping in the direction water travels. Sealant is a secondary defence with a much shorter service life, shorter again in this heat, so a flashing that has lifted or corroded and then been sealed will usually leak again within a season or two.

Is sealant ever the right answer

Yes, in two situations. As a secondary defence on top of a sound detail, which is what it is designed for, and as a deliberate temporary measure to get a building through weather while a proper repair is scoped. What it cannot do is make a failed flashing behave as though it had not failed.

What does flashing repair cost in Kenner

Estimated at $350 to $1,200, driven by the length of the run, access and whether the covering has to be lifted to get new metal properly underneath it. Every figure here is an estimate and a written price follows a look at the detail.

Could the problem be the chimney rather than the roof

It can be, and often is. A cracked crown, failed mortar joints or water tracking behind cladding will defeat new flashing entirely. That is masonry work rather than roofing, and we will tell you that is what you have instead of fitting metal to a problem above it.

How do I know it is the flashing and not something else

You may not, and you do not have to. Water shows up a long way from where it enters, so the joint you can see is not necessarily the one that failed. Leak detection traces it back before anybody prices a repair.

Get the flashing rebuilt, not resealed with the value written down first

Flashing works by shape, by metal lapped in the direction water travels, and sealant over a failed detail buys a season at most. We put the scope and the total estimated value in writing before anything is opened up, take the paperwork question to the Kenner Permitting Office rather than guessing at it, and tell you plainly when the failure is in the masonry above the flashing and not in the roof at all. If you would rather start in writing, tell us what the job involves and we will come back with an estimate.
