A roof inspection for insurance is an ordinary roof inspection written for a third party. The methods are the same ones used on any commercial roof: a walk, the perimeter and penetrations, the drainage, often a scan and sometimes cores. What differs is who reads the result, and that changes the standard the documentation has to meet.
The reader is an underwriter or an adjuster who will never stand on the roof and who has no way to check anything the report asserts. Everything that persuades in person, the tone of a contractor’s voice and the fact that he showed you the problem, is unavailable. What remains is dates, photographs, positions on a plan and plain statements of what was observed.
The four occasions a carrier asks
| Occasion | Who asks | What they want to establish |
|---|---|---|
| New policy | Underwriter | What the roof is, how old, what condition |
| Renewal or nonrenewal | Underwriter | Whether condition has changed since last time |
| Certification request | Underwriter or lender | That the roof has a stated remaining life |
| After damage | Adjuster | What was damaged, by what, and when |
The first three are condition questions and the owner usually commissions the inspection. The fourth is a causation question, the carrier sends its own adjuster, and an owner who wants an independent record commissions one as well. They are different documents answering different questions, and a report written for one is a weak answer to the other.
What changes when the audience is an insurer
Five things, and all of them are about evidence rather than method.
- Dates become load bearing. When the inspection happened, when the photographs were taken, when any repair was completed.
- Age needs a basis. Not a guess. Permit records, the manufacturer’s markings, a core showing the layers, or an estimate with the reasoning stated as an estimate.
- Condition has to be described, not graded. A grade of fair tells an underwriter nothing. What the laps look like, how the drains perform, whether the flashings are sound and whether the field is dry does.
- Photographs must locate themselves. Overview shots that place the close ups, and a roof plan that positions both.
- Limitations must be stated. Areas not reached, methods not used, questions the inspection cannot answer. A report that admits its limits is more credible than one that does not.
What a good inspection report contains covers the general form. For an insurance audience the same report simply has to be stricter about all five.
What the inspection records
- The roof system, how it was identified and whether there is more than one on the building.
- The construction beneath it, as far as it can be established without opening the roof.
- The age, with the basis for the figure.
- Drainage performance and any evidence of standing water.
- Condition of the field, the laps, the perimeter and every penetration.
- Evidence of prior repairs, and whether they were done properly.
- Interior evidence of past or current water entry.
- A remaining service life figure, with the reasoning that produced it.
Where a moisture survey is included, it answers the question an underwriter cares about most on a flat roof: how much of the assembly is already wet. An infrared scan maps that, and the map is far more persuasive than a sentence saying the roof appears dry.
Who should carry it out
Carriers differ in what they will accept, and some will not take a report from the contractor who then quotes the repair. That is a reasonable position and worth anticipating rather than arguing with.
The question to ask the carrier before booking is specific: who may carry out the inspection, what qualifications are required, what the report must cover, and in what format it should arrive. Choosing an inspector covers the credentials side, and the independence requirement is the one that most often decides who gets the work.
Timing, which decides more than it should
An inspection commissioned four months before a renewal and one commissioned four weeks before produce the same report and a completely different outcome, because only the first leaves room to repair what it finds and document the repair.
Work backward from the date the documentation has to be complete. Allow for the visit, for the report to be written, for a contractor to schedule a repair, for weather, and for a short note confirming the work was done. That is months, not weeks, and the period after a regional storm is the hardest time to get anybody on a roof.
What an inspection cannot do
An inspection reports on a roof. It does not decide anything about a policy, and a report that implies otherwise is overreaching.
It cannot say whether a loss is covered. Coverage is a question about policy wording and about cause, and an inspector describing a roof is not in a position to answer it. What the report can do is record the facts the question will be decided on.
It cannot date damage precisely. It can say whether a defect is fresh, weathered or long standing, and that is a range rather than a date.
It cannot speak for the carrier. If a report asserts that a roof qualifies for a given treatment or that an insurer will accept something, treat that as a sales sentence rather than a finding. Ask the carrier.
What it can do is remove the guesswork from an exchange that otherwise runs on assumption, and give the owner a document of their own that exists whatever anybody else concludes.
On commercial buildings specifically
Three things come up on commercial property that rarely arise on a house.
More than one roof. A building extended over decades has several roof systems of different ages, and an underwriter given a single condition for the whole address is being given an average that describes none of it. Each area needs its own entry.
Rooftop equipment. Units, screens, ducts and the people who service them are a recognized source of roof damage. An inspection that records their condition and the state of the roof around them is answering a question the carrier has.
Repeat format. Where the same inspection is to be run annually, having the second report in the same structure as the first makes change visible at a glance. Ask for a format that can be repeated rather than a one off document.
Where this goes wrong
- The report grades the roof and never describes it, so nothing in it can be checked.
- No age basis is given, so the oldest plausible age gets assumed.
- Photographs have no overview and no position, so they prove nothing about location.
- The repairing contractor wrote the report, and the carrier sets it aside.
- The inspection happened too late to act on, so a defect is disclosed rather than a repair.
- Nobody asked the carrier what it wanted, and the survey that arrives is not the one required.
Where to go next
If what you need is a stated remaining life rather than a condition report, roof certification is the document that does that and it has a different scope. If damage has already happened and the question is what caused it, a storm damage inspection is the inspection to ask for, because attribution and condition are not the same exercise.
Common questions
Why do insurers ask for a roof inspection?
Because the roof is the part of a building most likely to produce a claim, and its condition cannot be judged from an address. An inspection gives the underwriter the age, the construction and the current condition in a form they can file and rely on.
- Roof claims are frequent and expensive to settle
- Age alone does not describe condition
- Carriers cannot inspect every building themselves
- A report moves the roof from unknown to measured
- The same document can serve several purposes later
It helps to see it from the carrier's position. They are pricing a risk they cannot see, and in the absence of information they price for the worst reasonable case or decline the risk entirely. A report that says what the roof is, how old it is and what condition it is in replaces that assumption with a fact. That is as likely to work in the owner's favor as against, which is the part owners tend not to expect.
Does the insurer choose the inspector, or do I?
It depends who asked and why. A carrier investigating a claim sends its own adjuster. A carrier asking for documentation at underwriting or renewal normally leaves the choice to the owner, subject to requirements about qualifications and about independence from the repair work.
- An adjuster works for the carrier and reports to it
- An inspection you commission is your document
- Carriers may set qualification requirements
- Some will not accept a report from the repairing contractor
- Ask what the requirements are before booking
The two are not substitutes and both can exist on the same roof. An owner who commissions an inspection has a record of condition written for them, whatever the carrier's own adjuster concludes. Ask the carrier in writing what it needs: who may carry out the inspection, what the report must cover and in what format. Five minutes of asking avoids commissioning a survey that is then refused for a reason nobody mentioned.
What does an underwriter want to see in the report?
Facts that can be filed. The roof type and construction, the age or an estimate of it with the basis stated, the current condition, the remaining service life with reasoning, and photographs that show the roof rather than illustrate an opinion about it.
- System type and how it was identified
- Age, with the evidence behind the figure
- Condition described concretely, not graded loosely
- Remaining life with the reasoning shown
- Dated photographs that cover the whole roof
What gets a report set aside is unsupported adjectives. Good, fair and poor mean nothing without the observations behind them, and an underwriter reading fair has learned nothing at all. A sentence naming the system, describing its condition at the laps and the details, recording how the drainage performed and stating the basis for the age estimate is worth a page of grading. Ask for the report in the carrier's own format where one exists, because a document that arrives in the shape the reader expects gets read rather than queried.
What happens if the inspection finds problems before a renewal?
You find out before the carrier does, which is the whole point of commissioning it yourself. Defects found with time in hand can be repaired and documented as repaired, and a repaired defect with evidence reads very differently from an unrepaired one found later.
- Early findings leave time to act on them
- Repairs should be documented with photographs and invoices
- A follow up note recording the repair is worth asking for
- Deferred items are better disclosed than discovered
- An inspection does not have to be sent anywhere
The order of events matters more than the findings. An owner with a report, a set of repair invoices and a photograph of the completed work is presenting a maintained building. An owner whose first information about the roof arrives in a letter from the carrier is responding to somebody else's account of it. Neither outcome is guaranteed, but only one of them is in the owner's hands, and the difference is usually a matter of weeks.
How long before a renewal should the inspection be done?
Early enough to repair anything it finds and still have the repair documented before the renewal date. That means months rather than weeks, because scheduling an inspection, receiving the report and getting a contractor on the roof all take time.
- Allow time for the report to be written, not just the visit
- Repairs need scheduling and weather
- A reinspection or a note confirming repairs takes longer still
- Roofers are busiest after storms, which is when you may need one
- A recent report carries more weight than an old one
Working backward from the renewal date is the practical method. Decide when the documentation needs to be complete, allow for a repair window before that, allow for the report before that, and book the inspection accordingly. Owners who leave it until the renewal papers arrive are usually left disclosing a defect rather than a repair, which is a worse position for no reason other than timing.
