What is roof restoration?

There is no standard definition, which is the honest answer and the reason this page exists. In the sense we use it, it means renewing the components that fail first, the flashings, boots, valley metal and underlayment at penetrations, while keeping a covering that still has service life in it. Four quite different jobs get sold under the same word.

How much does roof restoration cost in Gretna?

The trade rule of thumb is 40 to 60 percent of what replacing the same roof would cost, and it is a rule of thumb rather than a measurement. It is only worth anything beside a real replacement figure for your own roof, which is why we quote both for the same roof. What moves the number is how many penetrations and flashing details are on the list.

Is restoration cheaper than replacement?

Yes, and that is the point of it, but only where the covering has life left. Spending half the cost of a new roof on a covering that has two years in it is not a saving. That is why the assessment comes before the price rather than after it.

Does a roof restoration need a permit in Gretna?

It depends what is on the list. Act 239 of 2025 introduced the requirement, now carried at La. R.S. 37:3737(I), which covers reroofing and roof construction, and the word restoration appears in neither the statute nor the local notices. If the covering is being replaced it is a reroof and it is permitted and inspected, through the City of Gretna Building Department inside the limits or Jefferson Parish outside them. If it is not, we confirm the position with the office at file before starting.

How do I know whether to repair, restore or replace?

Our Gretna repairs page sets out the signals: a repair is right where the covering elsewhere is sound and within its service life, and it stops being right where the same slope has already been patched twice, where seal strips are broken well beyond the visible gap, or where the covering either side is at the end of its life. Restoration is for the middle case, where the covering is sound but the details around it have failed.

How many years does a restoration add?

Estimated at five to ten, and it depends entirely on what was done. Replacing failed flashings, boots and underlayment at every penetration buys real time. Cleaning and resealing buys much less. Neither puts granules back on a shingle.

Is a roof coating the same as a restoration?

No. A coating is a liquid applied membrane over the existing covering and it is a separate service with its own Gretna page, useful on low slope and metal roofs. A restoration replaces failed components. Where a quote uses the two words as though they mean the same thing, ask which one is actually being supplied.

What is guaranteed afterwards?

The workmanship on what we did, and the manufacturer terms on any component we supplied. Nothing on this page warrants the age of the covering that stayed on the roof, and any contractor offering a long guarantee on twenty year old shingles somebody else laid is offering something they cannot stand behind.

Gretna roof restoration at a glance

Restoration sits between repairing single defects and replacing the covering, and it is estimated at 40 to 60 percent of what replacing the same roof would cost. It is worth having when the covering has life left in it, and it is worth refusing when the quote refuses to list what is included.

Estimated cost

40 to 60% of a replacement

A trade rule of thumb rather than a measurement, useful for a first budget and nothing more. A particular roof can land outside it in either direction, which is why we quote the restoration and the replacement side by side for the same roof. Call Big Easy Roofing on (504) 800-8196.

Who permits a reroof

City or parish, by boundary

If the restoration includes replacing the covering it is a reroof, which is permitted and inspected through the City of Gretna Building Department at 740 2nd Street inside the city limits, or through Jefferson Parish outside them. A Gretna postal address does not tell you which.

What decides the permit

The work, not the word

Restoration appears in neither the statute nor the local notices. Whether a permit is required follows what is actually being done to the covering, which is why the itemised list matters before anything starts.

Possible added service life

5 to 10 years

A possibility on a suitable roof rather than a prediction for yours, and it depends entirely on what was on the list. Replacing failed flashings and underlayment at every penetration buys years. Cleaning and resealing buys considerably less, and neither puts back a covering that has lost its granules.

What it cannot do

Reverse ageing

Restoration renews details and components. It does not renew the covering itself, so a covering whose seal strips are broken well beyond the visible gap, or that is at the end of its life either side of the damage, is a replacement whatever the quote is headed.

Estimated time on site

2 to 4 days

Longer than a repair, shorter than a replacement, and driven by how many penetrations, valleys and flashing details are on the list rather than by the size of the roof. The written scope carries the figure for your own job.

There is no definition of roof restoration. It is not a code term, it does not appear in Louisiana Act 239 of 2025, and it is not in the City of Gretna or Jefferson Parish permitting notices. Four quite different jobs get sold under it, ranging from a clean and a reseal to stripping the covering off and putting a new one back. They are not variations on one price, and two of them sit on opposite sides of the permit question. The word tells you nothing at all.

So the only question worth asking a contractor is which line items are included. A restoration that replaces the flashings, the boots, the valley metal and the underlayment at every penetration is a substantial piece of work with years in it. A restoration that means a pressure wash and a tube of sealant is a cleaning bill. Both get quoted with the same word on the top of the page, and only the itemised list separates them.

Four jobs sold as restoration and what each one really is

Every row below gets sold as a roof restoration. Four of them are different jobs at different prices, and two of those four sit on opposite sides of the permit question. The fifth is not a job at all, it is what a quote looks like before anyone has written the scope down.

What gets sold as restoration	What the work actually is	Permit position in Gretna	The honest name for it
Flashings, boots, valley metal and underlayment renewed at every penetration	The covering stays, every detail that fails first is replaced	Confirm with the city or parish	A real restoration
Clean, reseal penetrations, swap a handful of shingles	Housekeeping with a few components changed	Not a reroof	Maintenance, and it has its own page
Strip the covering, keep the deck, lay a new covering	A replacement with the word changed	A reroof. Permit and inspection	A replacement
Liquid coating rolled over the existing covering	A surface membrane, useful on the right roof	Not a reroof	A coating, and it has its own page
A restoration package with no itemised list	Unknown until somebody writes it down	Unknown	Not yet a quote

Which row you are being sold is the thing to settle before any figure is discussed, because the rows are not variations on one price. The replacement figure for a Gretna roof is on our roof replacement page, and what a coating can and cannot do for a roof that is already failing is on our coating page, so neither is re-argued here. Call (504) 800-8196 and we will put the line items in writing first, then quote the restoration and the replacement side by side.

Restoration and the 2025 rule which does not use the word

Louisiana changed its roofing permit rules in 2025 and the change is written around reroofs and new construction. Restoration is not named in it, which cuts both ways: it is not exempt, and it is not automatically caught. What is being done to the covering decides.

What the 2025 rule covers

Reroofs and new build

Act 239 of 2025 introduced the requirement, now carried at La. R.S. 37:3737(I), requiring a parish or municipality that issues construction permits to permit and inspect roof construction and reroofing. Both the City of Gretna and Jefferson Parish issue construction permits, so both permit residential reroofs within their jurisdictions.

How the inspection is evidenced

Geotagged photographs allowed

R.S. 37:3737(H) allows a code enforcement officer to accept location verified geotagged photographs for the roofing inspection. That is a general permission across Louisiana rather than a specific parish checklist. The photograph set the homeowner wants and the set the office may want tend to be the same photographs.

Where restoration sits

It depends on the list

The word appears in neither the statute nor the local notices. A restoration that replaces the covering is a reroof by any reading. One that renews flashings and underlayment without replacing the covering is a scope question, so we confirm the position with the office at file before starting rather than assuming it.

Why this matters to you and not just to us

Unpermitted work follows the house

A reroof done without the permit it needed can raise compliance and disclosure questions later, at a survey or at a sale, and the records sit with the property rather than with the contractor who suggested the friendlier word. That is why our own scope of work states plainly whether your job is a restoration or a reroof before anything starts.

How to read a restoration quote in ninety seconds

Look for four things by name: which flashings are being replaced and which are being resealed, whether the pipe boots are new components or sealant, whether any underlayment is being renewed and where, and whether any decking is included or excluded. A quote that names none of those is a price without a scope.

Then ask one question: is the covering staying on the roof. That single answer decides whether you are buying a restoration or a replacement, and it decides the permit.

What a restoration cannot reach

It cannot reach the deck. If the sheathing has taken water the covering has to come off to get at it, at which point the job is a replacement, and any quote that promises to sort out decking without lifting the covering is describing something that cannot be done.

It also cannot fix ventilation faults or a covering laid to the wrong fastener pattern, because both of those live under the shingles. Those are worth knowing about before you spend forty to sixty percent of a new roof on the roof you already have.

What this climate does to a restored roof

Three things decide whether a restoration in Gretna is worth the money, and none of them is the brand of sealant. Two of them are about what has already happened to the covering, and the third is about what is hiding underneath it.

Granule loss does not come back

Heat and ultraviolet strip the granule layer that protects an asphalt shingle, and once it has gone the shingle is on borrowed time whatever is done to the flashings around it. Restoration renews components. It does not renew the covering.

That is the first thing to look at on a roof somebody has offered to restore. If the granules are in the gutters in quantity, the money is better spent once, which is the same conclusion our Gretna repairs page reaches from the other direction when it says a survey costs less than a third repair.

Sealant has a shorter life here than the roof does

A restoration that leans on sealant rather than on replaced components is buying time in a climate that is hard on sealant. Heat cycling and ultraviolet work on it constantly, and it is applied in exactly the places water is trying hardest to get in.

Sealant belongs in a restoration as a finishing detail rather than as the product being sold. Where a flashing has failed, the answer is a new flashing, and a quote that reaches for a tube instead is quoting a different job.

A layered roof hides its own condition

Where a covering has been laid over an older one, nobody can see the deck, the original flashings or what the first covering is doing. A restoration on a layered roof is work done on top of unknowns, and the unknowns are the expensive part.

We treat that as a replacement question rather than a restoration one, and we will say so at the quote rather than after opening the roof. It is also the reason a second covering is worth knowing about before any restoration figure is discussed at all.

Big Easy Roofing Process

Three steps, and the first one exists to tell you which of the four jobs on this page you are actually looking at before anybody prices anything.

Establish which job this is

The covering assessed for whether it has service life left, the penetrations and flashings checked individually, and the roof checked for layering. That is what separates a restoration from a replacement, and it happens before a figure is written down.

Itemise the list, then price it

Every component named: which flashings are replaced, which boots are renewed, where underlayment is being changed, and what is excluded. Decking is excluded rather than allowed for, because it cannot be seen while the covering stays on. If opening the roof finds damaged decking, work stops and you get a separate scope before it goes on.

Settle the permit position, then work

If the scope makes it a reroof it is permitted and inspected as one, and if it does not we confirm that with the office at file rather than assuming. Call (504) 800-8196 to get the roof looked at.
