Do I need a permit to replace my roof in LaPlace?

Yes. Louisiana requires any municipality or parish that issues construction permits to permit and inspect roof construction and reroofing, and that requirement is carried at La. R.S. 37:3737(I). St. John the Baptist Parish issues permits, so a LaPlace reroof is permitted under that rule.

How is the LaPlace permit application filed?

Online through MyGovernmentOnline at mgoconnect.org/cp/portal or in person at the St. John the Baptist Parish government building at 1811 W. Airline Highway in LaPlace. Downloadable PDF applications are also posted on the parish Building Permits page. Office hours are 8am to 4:30pm Monday to Friday.

What does a roofing permit cost in LaPlace?

The parish publishes a permit fee sheet and the residential re-roof line comes from that sheet at review, so the amount is set at the parish level for the specific application. Any figure quoted before the paperwork goes in should be checked with the Permit Division on (985) 651-5565 before you rely on it.

Is LaPlace incorporated?

No. LaPlace is a census-designated place with a 2020 population of 28,841, on the east bank of the Mississippi in St. John the Baptist Parish. The historic parish seat is Edgard; the parish government building sits inside LaPlace at 1811 W. Airline Highway, so parish services for a LaPlace address are filed at a LaPlace address.

Who reviews the permit application?

The St. John the Baptist Parish Permit Division reviews applications, on (985) 651-5565, with Code Enforcement Inspectors carrying out building inspections on (985) 359-1195. Both offices are on the first floor of 1811 W. Airline Highway, open 8am to 4:30pm Monday to Friday excluding government holidays.

What does a roof replacement cost in LaPlace?

A full asphalt replacement is estimated at $7,000 to $18,000, moved by size, pitch and how many layers have to come off. Standing seam metal and complex roofs with several valleys run higher. Every figure here is an estimate and a written price follows a measurement.

How do I check my roofer is licensed for the work?

Ask for the Louisiana state licence number and its expiry date. From 1 January 2026, work on a residential roofing system valued at seven thousand five hundred dollars or more requires the Residential Roofing or Residential Construction classification under R.S. 37:2156.4. That covers quoting and estimating the work, not only performing it.

How long does a LaPlace replacement take?

Most single family roofs are a day of work once the crew is on site. The calendar is usually set by the permit rather than by the roofing, and in LaPlace that means the timeline depends on when the Parish Permit Division reviews the application and issues the permit.

LaPlace roof replacement at a glance

A full asphalt replacement on a LaPlace house is estimated at $7,000 to $18,000. LaPlace is an unincorporated community in St. John the Baptist Parish, and the parish government building at 1811 W. Airline Highway sits inside LaPlace itself, so the permit for a LaPlace reroof is a parish permit filed at a LaPlace address.

LaPlace is unincorporated but the parish is in LaPlace itself

Parish government in LaPlace

St. John the Baptist Parish runs permit review out of the government building at 1811 W. Airline Highway, and that building is inside LaPlace itself. A LaPlace resident files at the parish, and they file it at the same town they live in.

The application goes through MyGovernmentOnline

MGO portal or in person

The Parish Planning and Zoning page directs applications to be submitted online at mgoconnect.org/cp/portal or in person at 1811 W. Airline Highway. Most cluster cities use MGO the same way; LaPlace is not the outlier here.

LaPlace is a large CDP

28,841 people, 2020 census

LaPlace is the largest community in St. John the Baptist Parish, on the east bank of the Mississippi River about twenty five miles west of New Orleans. Unincorporated status is the norm for the parish, so a LaPlace mailing address is expected to be a parish permit, not a city one.

The parish fee comes with the review

Cost varies, set by the parish

St. John the Baptist Parish publishes a permit fee sheet, and the residential re-roof line comes from that sheet at review rather than from a headline figure quoted before the paperwork goes in. Any number quoted before the application is a guess.

State law applies here too

R.S. 37:3737(I)

Louisiana requires any municipality or parish that issues construction permits to permit and inspect roof construction and reroofing. St. John the Baptist Parish issues permits, so a LaPlace reroof is permitted under state law regardless of the parish's own fee structure.

The Mississippi and the highways bound the town

East bank, elevation ten feet

LaPlace sits on the east bank of the Mississippi River at elevation ten feet, with Airline Highway and Interstate 10 running through the town. Low elevation and heavy rainfall put the covering choice and the drainage detail on the front line, and both sit inside the written scope of every LaPlace replacement.

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.

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 the covering is off, so call Big Easy Roofing on (504) 800-8196 for a written price.

Four coverings, and what each is really buying you

The covering choice on a LaPlace house is mostly a question of how long you intend to hold the property. Wind exposure and heavy rainfall push the wind rating and the flashing detail up the priority list; the covering itself is one line of a longer scope.

Covering	Estimated installed	Realistic service life	What decides it
Architectural asphalt shingle	$7,000 to $18,000	20 to 30 years	The default, and what the FORTIFIED standard is usually written around
Three tab asphalt shingle	$6,000 to $12,000	15 to 20 years	Cheaper now, and the shortest life of the four in this heat
Standing seam metal	$18,000 to $40,000	40 to 60 years	The longest life and the highest number, for a long hold
Modified bitumen on a low slope	$9,000 to $20,000	15 to 25 years	Only where part of the roof is genuinely low slope

Every figure is an estimate and none of it is a quote. Pitch, layers, decking condition and access move all four bands. Call for a written price on your LaPlace roof.

The LaPlace permit route goes through St. John Parish

LaPlace is unincorporated, so the permit for a reroof is a parish permit rather than a city permit. What is different is where you file it. St. John the Baptist Parish runs its Planning and Zoning office out of the government building at 1811 W. Airline Highway, which is inside LaPlace itself.

The permit itself is not optional

Statewide since 2025

Louisiana requires any municipality or parish that issues construction permits to permit and inspect roof construction and reroofing. The requirement came in through Act 239 of 2025 and is carried at La. R.S. 37:3737(I). St. John the Baptist Parish issues permits, so a LaPlace reroof is permitted here whichever intake route is used.

Where the application goes

St. John the Baptist Parish directly

The Parish Building Permits page directs applications online through MyGovernmentOnline at mgoconnect.org/cp/portal or in person at 1811 W. Airline Highway, LaPlace LA 70068. The Permit Division is on (985) 651-5565, and the Code Enforcement office is on (985) 359-1195. Office hours are 8am to 4:30pm Monday to Friday.

The parish fee comes from the fee sheet at review

Not from a headline figure

St. John the Baptist Parish publishes a Permit Fee Sheet PDF that the reviewer refers to when the application is reviewed, and the residential re-roof line comes from that sheet at review rather than from a rough number quoted at the door. A figure printed on a search result page should be checked with the Permit Division before you rely on it.

The parish government building is in LaPlace itself

A short walk or drive, not a trip to a distant seat

The parish government building is at 1811 W. Airline Highway in LaPlace itself, so a LaPlace resident files at their own address rather than driving to a distant parish seat. That is a genuine local practical fact, not a hurdle, and it is what makes the in-person intake option realistic in a way it is not in every parish.

Why the intake route matters as a practical matter

Filing through MyGovernmentOnline puts the application into an online account that both the parish reviewer and the roofer can see. In person at the counter puts it into the physical inbox on the first floor of 1811 W. Airline. Either route is standard for St. John the Baptist Parish; the roofer files whichever route the parish prefers on the specific application.

What that changes for the homeowner is the pattern of who has the answer at any moment. A parish reviewer either has the file open or has not; progress questions go to the Permit Division on (985) 651-5565 rather than to a login screen.

Ask any roofer for a licence number, and check the date

From 1 January 2026 the Residential Roofing or Residential Construction classification is required to advertise, solicit, offer, quote, estimate, supervise or perform work on a residential roofing system valued at seven thousand five hundred dollars or more. That is R.S. 37:2156.4, it covers quoting the work and not only doing it, and the wording is "or more", not "over".

Ask for the Louisiana state licence number and its expiry date, and verify it with the State Licensing Board for Contractors rather than taking the number on the paperwork as proof the classification is current.

What a LaPlace address changes about the job

LaPlace sits on the east bank of the Mississippi River in St. John the Baptist Parish, about twenty five miles west of New Orleans, at elevation ten feet. It is unincorporated and the parish government building is at 1811 W. Airline Highway in the town itself, so three things follow from that on a reroof.

The permit paperwork is a parish permit

Because LaPlace is unincorporated, a reroof permit is a St. John the Baptist Parish permit rather than a city one. Because the parish government building is inside LaPlace, the paperwork does not have to travel far, and the in-person option is a realistic choice rather than a fallback.

The route the paperwork takes is what differs from Metairie (Jefferson Parish counter) or Kenner (its own city department). LaPlace goes through parish MGO or the parish counter at 1811 W. Airline.

The Mississippi and Airline are the landmarks the parish uses

LaPlace is bounded to the south by the Mississippi River and threaded by Airline Highway and Interstate 10 east to west, with the parish government building on the stretch of Airline that runs through town. The parish uses street addresses on that grid to route applications rather than parish-wide identifiers, so a specific LaPlace address is enough to open a file.

A LaPlace address is expected to be an unincorporated parish address, since the parish as a whole is largely unincorporated. There is no city-limits question of the kind that arises in Harahan or Gretna.

Heat and heavy rainfall age the covering at the details first

A covering in this climate almost never fails as a flat surface. It fails at the flashings, the valleys and the pipe boots, which is why those items sit inside a written scope on a replacement rather than being taken as read.

The other half of the ageing story is attic heat, and ventilation is the underpriced part of the fix. A sealed attic on a hot roof takes years off a shingle, so ventilation is on the scope rather than left as an option.

Big Easy Roofing Process

Four steps. LaPlace is a parish permit rather than a city permit, so the paperwork step is called out explicitly.

01 Confirm the LaPlace address with St. John Parish

A LaPlace mailing address is expected to be an unincorporated parish address, but the reviewer checks the address against the parish record before drafting the application. That decides which files the application is opened under.

02 Measure, inspect the deck and write the scope with its value

Squares, pitch, layers and the condition of what is under the covering. The construction value that comes out of this is what the parish reviewer uses.

03 File the Building Permit Application through MGO or in person

Applications go online at mgoconnect.org/cp/portal or in person at 1811 W. Airline Highway in LaPlace. The permit fee comes from the parish fee sheet at review, not from a headline figure quoted at the door.

04 Tear off, replace, and hand over the paperwork

The scope, the permit and the inspection sign off go to you together, which is what a future buyer or insurer asks for.
