Expert witness and technical review

The qualification, and why you can check it before you call

I hold two Florida licences, both public record and both verifiable before you spend a minute on the phone: CBC059592, Certified Building Contractor, and CCC1327217, Certified Roofing Contractor. Type either number into the Florida DBPR public licence search and you will see the status, the name attached, and the expiry date. I would rather you did that than take my word for it, because an expert whose own credentials cannot be checked is the first thing opposing counsel will go after.

Behind the numbers is forty-six years of field experience across building and roofing — not forty-six years of talking about construction, but of standing on decks deciding whether they could be repaired or had to come off, pulling permits, sequencing trades, and carrying the risk when the answer was wrong. That distinction matters in a deposition. A witness who has only read about a thing answers differently under pressure than one who has done it several thousand times, and an experienced cross-examiner knows exactly where to find the seam.

Holding both certifications is the part that is genuinely uncommon. A roofing licence covers the roof system; a building licence covers the structure the roof sits on — framing, walls, foundations, the envelope. A great many disputes land exactly on the line between those two, and when they do, two separate experts usually get retained, each able to speak only to their own side of the seam and each able to blame the other for what happened at it. One witness holding both certifications can address the building envelope and the roofing system as the single system they actually are, which is both cheaper for the retaining party and harder for the other side to pull apart.

Where a construction expert is actually useful

The questions I can answer with authority are narrower and more specific than whether the job was, broadly, a good one, and the narrowness is the point. An opinion that tries to cover everything persuades nobody; an opinion confined to what the witness can actually support survives.

The three questions I am most often the right person for: what was actually built — reading the physical evidence, the remaining materials, the fastening and flashing and sequence, and reconstructing what was done from what is there rather than from what the paperwork claims. What a reasonable contractor would have done — the standard-of-care question, which is not about perfection but about what a competent licence-holder in Florida, working to the applicable code, would have specified and done in the same circumstances. And whether a scope of work supports the conclusion drawn from it — the question that comes up when a report, an estimate, or a claim says more than the underlying work can carry.

Matters where I am commonly retained: construction-defect disputes, roofing failures and the question of whether they were storm-caused or age-caused, water-intrusion and the sequence of who-should-have-caught-what, scope and workmanship disputes between owners and contractors, and permit-and-inspection questions where unpermitted work has become the centre of the case. I am equally willing to be the expert whose honest reading is that the work was sound — an expert who only ever finds for the side that retained them is worth nothing, and good counsel knows it.

Storm versus age, which is where roofing cases live

A large share of roofing litigation and roofing claims turns on one question: did this roof fail because of a discrete event, or because it reached the end of its service life? The two are handled completely differently, the money is completely different, and the honest answer is frequently not the one either side wants.

The evidence that distinguishes them is physical and it is time-sensitive. Directional, matched damage consistent with a wind event reads differently from the uniform granule loss, brittleness, and multi-location failure of an aged system. Decking condition, the age and pattern of the failures, whether they share a cause, the state of the fasteners and the flashing — these are what an honest determination rests on, and most of them degrade or get covered up as time passes and repairs are attempted.

What I will do is read that evidence and say what it supports, with the reasoning stated plainly enough that a judge or a jury can follow it. What I will not do is reverse-engineer a conclusion to fit the retaining party's preferred outcome, because an opinion built that way does not survive a competent cross-examination and it takes the rest of the testimony down with it. In Florida specifically, the threat is wind rather than hail, and the building code reflects that — uplift, deck attachment, and roof-to-wall connections carry weight here that they do not carry in a hail region, and an out-of-state analysis that treats a Florida roof like a Midwest one is a vulnerability I can identify in the other side's report and will not create in my own.

The documentation is the part most experts get wrong

I build evidence systems for a living — that is the other half of what I do — and it has made me unusually particular about how an opinion is supported. The weakness in a great many expert reports is not the expertise; it is that the file behind the opinion was assembled after the conclusion was reached, and it shows.

Photographs with reliable timestamps, a chain of custody that holds, version history that shows what was known when, and a clear separation between what was observed and what was inferred from it — these are how my own platform records contracting work, because that is the standard a regulator or a court would apply to it. A file built to that standard going in is organised for scrutiny rather than braced against it, and the difference is visible the moment opposing counsel starts asking when each photograph was taken and how I know.

It also means I can be useful on the other side of the documentation question: reviewing the opposing expert's file for the gaps that competent cross-examination exploits — undated photographs, conclusions that outrun the observations, a scope that does not support the number attached to it, analysis that ignores the Florida-specific code. That review is often more valuable before a deposition than any affirmative opinion.

The line I do not cross

There are things a construction and roofing expert should refuse, and naming them is part of being credible on the things I will do.

I am not a public adjuster and I will not act as one. Handling or negotiating an insurance claim on someone's behalf is a separately licensed activity in Florida, governed by its own statutes, and I do not hold that licence. I can determine and testify to what the physical evidence shows about cause and condition; I cannot and will not represent a party in the claim itself, and any expert offering to do both at once is a problem for the case, not an asset to it.

I also stay inside my licences. For a question that needs a professional engineer's stamp — a structural calculation, a sealed design opinion — or for a trade outside building and roofing, the right answer is to bring in someone who holds the correct licence rather than stretching mine to cover ground it does not. An expert who claims competence outside their certification hands the other side the easiest impeachment there is.

How an engagement starts

The first thing is a conflict check, so the first message should name the parties involved. Nothing substantive happens before that clears, and raising it early saves both of us from a conversation that cannot go anywhere.

After that, what is useful to send is the matter type, the jurisdiction, the date by which you need an opinion, and a short description of what is in dispute. Detailed documents — reports, photographs, the opposing expert's file — can follow once there is a fit; there is no sense assembling a package for someone who turns out to be the wrong person for the matter.

You will get a straight answer about whether this is something I can support, and if it is not, I will say so plainly — and where I can, point you toward the kind of expert who would be a better fit. The work is Florida, where the licences are issued.
