Infrared Moisture Survey in Deltona, FL

Wet insulation is the line item that turns a repair into a replacement, and it cannot be seen from the roof surface. A membrane can look sound for years over insulation that holds water like a sponge, and the only way to know is to measure. Infrared moisture surveys and core cuts do that measuring. In Deltona, FL, where afternoon rain is routine from June through September and roofs spend months at high temperatures, hidden moisture builds quietly, and by the time a ceiling stains, the wet area is often far larger than the leak that revealed it.

Our survey gives the owner a map: where the roof is wet, how deep the wetness goes, and what portion of the roof is still dry and worth keeping. That map decides whether the right answer is a spot repair, a recover, a coating or a full replacement, and it is the strongest piece of evidence an owner can bring to a budget meeting or an insurer.

Membrane and gravel hide what is beneath them. Water that enters through a flashing or seam travels along the deck or through the insulation, and may never produce a drip. On a mechanically attached single-ply roof, water can soak insulation boards across dozens of feet from the entry point. On a built-up roof, the layers hold moisture between plies. Even a roof that has never leaked into the building can carry a heavy water load, adding weight and reducing thermal performance.

The cost of not knowing is large. A new membrane installed over wet board traps moisture and fails early. An owner who plans a recover without a survey may be paying for a roof that is dead on arrival. That is why we run the survey before any recover or coating proposal is finalized.

An infrared camera reads surface temperature. Wet insulation holds heat longer than dry insulation, so after a sunny day, wet areas stay warm into the evening while dry areas cool. A scan taken at the right hour, from the roof or from the air, shows warm patches that mark likely moisture. The pattern of those patches, whether a streak following a seam line or a blob around a drain, also hints at how the water got in. The method needs a clear day, a dry roof surface and a cooling period, which is why most scans happen near sunset.

Limits matter. Metal surfaces reflect heat and can confuse readings, ballast and gravel dampen contrast, and shaded areas behave differently. The camera produces a map of suspects, not a verdict. We mark each warm area on the roof with paint or flags and move on to confirmation, using a drone for aerial thermal passes where roof size warrants.

Every suspect area gets tested. Nuclear and capacitance meters read moisture at depth, and a probe or core cut confirms what the meter suggests. A core is a small circular cut through the membrane and insulation, which lets us see the layers, feel the board, read its condition and measure moisture directly. We take cores at wet readings and at dry ones, so the boundary of the wet area can be drawn with confidence. Each core hole is repaired immediately with compatible material and sealed.

A good survey ends with a roof plan, annotated with the boundaries of wet insulation, the locations of cores and photographs of what each showed. That plan is the basis for pricing a selective replacement, for sizing a recover and for deciding where a coating makes sense.

The wet area, as a share of the roof, shapes the financial decision. When wetness is confined to a few details such as a drain sump or a curb, targeted removal and replacement of the affected board can extend the life of the rest. When wetness covers a large part of the roof, selective repair costs begin to approach replacement, and the owner is better served to plan a full job. When the roof is nearly dry, a coating or maintenance program may be enough.

We give the owner those scenarios with their costs, and our due diligence roof surveys apply the same logic to a building being bought or financed. The survey is also useful for tracking: a second scan a year later shows whether wet areas are growing.

Certain buildings benefit most. A low-slope roof with insulation under the membrane on a retail, school or flex building near Howland Boulevard and the I-4 corridor can hold water over a wide area without a single drip. Medical and office buildings with sensitive interiors benefit from catching moisture before it reaches finished space. Roofs that have been recovered, patched repeatedly or exposed to storm damage are prime candidates, since their histories raise the odds of trapped water.

After a significant event such as Hurricane Milton in 2024, when parts of Volusia County took over a foot of rain, a survey shows whether storm water got into roofs that appeared undamaged. The same applies in Deltona and Orange City after any storm that left roofs wet for days.

Scheduling follows weather. The roof must be dry on the surface and have absorbed sun during the day. Evening scans after a warm, clear day work best, and an overcast stretch can force a delay. In Central Florida, where summer afternoons bring storms, the best windows are often in the dry months or the day after a clear spell. We tell the owner what window to expect and adjust if the forecast changes.

Because roof access is needed for meters and cores, we coordinate with building managers on hatches, ladders and any equipment that must stay powered. Core repairs are done on the same visit. The written survey follows once the field data is plotted, and any area that shows active leaking is flagged for the same-day dry-in rather than waiting for the report.

Can an infrared scan find every wet spot?

No, and the scan is one of three tools. Warm patches show likely moisture, meters read it at depth, and cores confirm it. Gravel, metal and shade can mute the scan, so we add meter grids in those areas. The combined result is far more reliable than any single method.

Will cores damage my roof?

Each core is a small circular cut, and we patch it with compatible material before leaving. A properly repaired core hole is not a meaningful weak point. The information gained is worth far more than the small cut, because it allows the owner to avoid replacing dry material or keeping wet material.

How much of my roof should I survey?

Survey the whole roof. A partial scan can miss wet areas that change the decision, and covering the full area is the only way to draw a boundary. Smaller roofs are quick to scan, and large ones can be scanned by drone-assisted thermal passes.

My roof has never leaked into the building. Is a survey a waste?

Not when the roof is old or has been patched. Water can sit in insulation for a long time before showing inside, so absence of leaks does not mean dry insulation. A survey establishes a baseline and often finds problems at drains and curbs.

Does a survey help with an insurance claim?

It helps when the question is whether storm water entered the roof system. Dated scans and core results show the wet areas, and our written findings separate recent storm water from long-term moisture. Coverage decisions belong to the carrier.
