What does a commercial roof inspection include?

The membrane and its seams, every flashing and penetration, edge and perimeter metal, drainage and ponding, and a moisture survey of the insulation under the membrane. The last of those is what separates a commercial inspection from a look round, because it is the finding that decides whether the next job is a repair or a replacement.

Why does wet insulation matter so much?

Three reasons and all of them cost money. It stops insulating, so the building costs more to condition. It gets heavy, adding load the roof was not designed for. And it holds water against the deck, which is where corrosion or rot starts. It also spreads well beyond the breach that let the water in, so the area involved is rarely small once it shows inside.

How do you find water under a membrane?

Infrared thermography after sunset, because wet insulation holds heat longer and shows up against the dry roof around it, or a capacitance meter where conditions do not suit infrared. Both find candidate areas. A core cut is the only conclusive method, because it is the only one where somebody physically looks at the insulation.

Why does the infrared survey have to be in the evening?

It relies on a temperature differential and a dry surface. The roof has to have taken heat during the day and be releasing it after sunset for the wet areas to stand out. In south Louisiana that means a clear evening after a dry day, which is a genuine scheduling constraint rather than a preference.

Are core cuts going to damage my roof?

A core cut removes a small section and it is made good the same visit. It is destructive by design, which is why it is used to confirm a suspicion rather than to hunt for one. The alternative is pricing a replacement on an estimate of how much insulation is wet, which is a far more expensive kind of uncertainty.

Does a commercial roof inspection need a permit?

No. An inspection is not construction, so it sits outside La. R.S. 37:3737(I) entirely. Work that follows from it may need one: a reroof does, and is inspected, through East Baton Rouge Permits and Inspections or through St. George, Baker, Zachary or Central depending on the address.

Is the parish inspection the same as this?

No, and it is worth being clear about. The inspection that follows an Act 239 permit checks new work against the code. It is a compliance check on what has just been built, not a condition survey of an existing roof, and it does not tell you how much life is left in one.

Will skipping inspections affect my warranty?

It can. Manufacturer system warranties commonly carry inspection and maintenance conditions and requirements about how repairs are carried out. The terms vary by manufacturer and by the warranty issued, so your own document is the authority. It is worth reading before there is a reason to.

How often should a commercial roof be inspected?

Twice a year is the common commercial pattern, one survey before the summer storm season and one after it, plus a look after any event that could have moved something. That includes work by other trades on the roof, which is the one people forget.

What do I actually get at the end?

A report with the findings photographed and located, ranked by whether they are admitting water now or will do, moisture areas marked on a roof plan with the cores that confirmed them, and a recommendation with the reasoning set out so it can be argued with rather than simply accepted.

Commercial Roof Inspections in Baton Rouge, LA

Big Easy Roofing inspects commercial roofs across Baton Rouge and East Baton Rouge Parish. On a low slope roof the expensive problem is under the membrane rather than on it, so an inspection that only reports what can be seen from the surface has looked at the cheapest part of the roof.

Baton Rouge commercial roof inspection at a glance

A commercial inspection has one job that a residential one does not: establishing whether the insulation under the membrane is wet. That single question decides whether the next intervention is a repair, a recover or a full tear off, and it cannot be answered by looking at the roof.

What is inspected

The assembly, not the surface

Membrane and seams, every flashing and penetration, drainage and ponding, perimeter and edge detail, and the moisture condition of the insulation below. Call Big Easy Roofing on (504) 800-8196 to book it.

Who permits new work

East Baton Rouge Parish

An inspection needs no permit; it is not construction. Where it leads to a reroof, that is permitted and inspected through Permits and Inspections, or through St. George, Baker, Zachary or Central if the address sits there.

The parish inspection is a different thing

Compliance, not condition

The inspection that follows an Act 239 permit checks new work against the code. It is not a condition survey of your existing roof and it does not tell you how much life is left in one. Those are two separate exercises with two separate purposes.

What confirms wet insulation

A core cut

Infrared and capacitance surveys find candidate areas. A core cut is the only method that is conclusive, because it is the only one where somebody physically looks at the insulation. It is destructive, so it confirms rather than searches.

What you get

A report you can act on

Photographed findings, defects ranked by whether they are letting water in now or will do, moisture areas marked on a roof plan, and a recommendation with reasoning rather than a verdict.

What it is worth over time

A roof file

One inspection is a snapshot. A series of them is a record of how the roof is changing, which is what turns a roof from an unpredictable expense into a planned one.

The reason commercial roof inspection is a distinct service rather than a look round is that the failure that matters most is invisible. Water that gets past a membrane does not usually run straight through to the ceiling. It soaks into the insulation and spreads sideways, and a small breach can wet an area many times its own size before anybody inside the building notices anything at all.

Wet insulation has three consequences and all of them cost money. It stops insulating, so the building costs more to condition. It gets heavy, which adds load the roof was not designed to carry. And it holds water against the deck, which is where corrosion of a steel deck or rot in a timber one begins. By the time it announces itself inside, the area to be replaced is rarely small, which is why the point of a survey is to find it while it still is.

How wet insulation is found and where each method falls down

There are three practical ways to find water under a membrane and none of them is right on its own. Knowing what each one cannot do is what stops a survey being sold as more certain than it is, and it is also what decides when the survey can be run at all.

Method	How it works	What it is good at	Where it falls down
Infrared thermography	Wet insulation holds heat longer, so it shows after sunset	Covering a large roof quickly and mapping the shape of an area	Needs a dry surface and a real temperature differential, so the window is narrow here
Capacitance or impedance meter	Reads electrical properties through the assembly	Spot checking, and working in conditions infrared cannot	Reads a depth rather than a certainty, and surface moisture skews it
Core cut	A small section is physically removed and examined	The only conclusive answer, and it shows the full build up as well	Destructive and local, so it confirms a suspicion rather than finding one
Visual inspection alone	Looking at the membrane and the flashings	Finding open seams, split flashings, blocked outlets and impact damage	Cannot see moisture at all, which is the finding that decides the cost

Used together they answer the question properly: infrared or a meter to find the candidate areas, cores to confirm them, and the confirmed areas marked on a roof plan so the quantity is known rather than guessed. In south Louisiana the infrared window is the binding constraint, because it needs a dry surface and a clear evening, which is a real scheduling limit rather than a preference. Call (504) 800-8196 and we will set the survey up around it.

What goes in the report and why the warranty depends on it

A commercial inspection report is a document other people have to be able to act on: a facilities manager, a finance director approving a budget, a buyer during a sale, and in some cases the membrane manufacturer. That shapes what has to be in it.

Findings ranked by urgency

Not listed alphabetically

Defects separated into what is admitting water now, what carries an elevated risk of doing so within the planning horizon, and what is a note for the file. A flat list of everything wrong with a roof is not a document anybody can budget against.

Moisture marked on a plan

With the cores that confirmed it

Candidate areas from the survey, the core cut locations, and what each core actually showed. That is what converts a survey into a quantity somebody can price, rather than a statement that there is water somewhere.

Warranties usually carry conditions

Read yours before it matters

A manufacturer system warranty commonly requires periodic inspection and maintenance, and requires that repairs are done in a particular way. Conditions vary by manufacturer and by the warranty issued, so the document itself is the authority. Losing cover you have already paid for is an avoidable way to lose money.

A recommendation with the reasoning

Not a verdict

Repair, recover or replace, with what led there set out so it can be argued with. An inspection that arrives at replacement without showing the evidence for it is a quote wearing a report as a disguise.

Ponding is a symptom, not automatically a defect

Water sitting on a low slope roof after rain is normal for a period. Water still sitting there long afterwards is telling you something about the falls or about the outlets, and the two have different fixes. Reporting every puddle as a defect is as unhelpful as reporting none of them.

What matters is where the standing water is relative to seams and penetrations, whether it is over an area the moisture survey has flagged, and whether the outlets serving it are clear. Those three together turn a puddle into a finding.

The edge is where wind takes a roof

Perimeter and edge metal do more structural work on a low slope roof than their cost suggests. Wind uplift concentrates at the edges and corners, and a membrane that is sound in the field can be let go by an edge detail that has loosened.

It is a small part of the roof and a large part of the risk, so it gets recorded specifically rather than as part of a general note about the membrane. Fixing loose edge metal is cheap. Replacing a roof that left in a storm is not.

How often a commercial roof here is worth looking at

Cadence is a judgement rather than a rule, and it depends on the assembly, the age and what the building does. What is not a judgement is that inspecting only after something has gone wrong makes the roof more expensive than it needed to be.

Twice a year is the common commercial pattern

One survey before the summer storm season and one after it is the pattern most commercial roof programmes settle on, because it puts an inspection either side of the period that does the damage. Debris clearance and outlet checks belong to the same visits.

That is a starting point rather than a prescription. A new roof under warranty, an old roof being nursed to a planned replacement, and a roof carrying heavy plant traffic are three different cases with three different answers.

And after any event that could have moved something

A named storm, hail, or work by another trade on the roof are all reasons to look, and the last of those is the one that gets forgotten. A mechanical contractor fitting a new unit creates penetrations somebody has to flash and record.

Looking soon afterwards matters because a breach that is found early is a repair, and the same breach found after a season of rain has soaked the insulation around it is a replacement of an area rather than a patch.

The value is in the series, not the visit

A single inspection tells you the condition today. Three years of them tell you the rate of change, which is the number a budget actually needs. It also puts the building in a position to answer questions during a sale or a refinance without scrambling.

That is the argument for keeping the reports in one place with the permit files, the warranty documents and the record of every repair. It costs nothing to keep and it is not reconstructable later.

Big Easy Roofing Process

Four steps, and the moisture survey is scheduled around the weather rather than around the diary, because that is what the method requires.

Walk the roof and record it

Membrane and seams, every flashing and penetration, edge and perimeter metal, drainage and ponding, and any evidence of work by other trades. Photographed and located on a plan rather than described.

Survey for moisture

Infrared after sunset on a dry clear evening where conditions allow it, a capacitance meter where they do not, and the candidate areas marked up. Booked around the weather because the method depends on it.

Confirm with cores where it matters

Core cuts taken in the flagged areas and made good, so the report states what was actually found rather than what the survey suggested. The build up gets recorded at the same time.

Report, ranked and priced

Findings separated by urgency, moisture areas marked on the plan, and a recommendation with the reasoning behind it. Call (504) 800-8196 to book the inspection.
