Core Sampling Tools

On a flat or low-slope roof, the membrane on top rarely tells the whole story. Core sampling tools let us cut a small, controlled test section down through the roofing system, so we can see the actual layers — membrane, insulation, cover board, and deck — instead of guessing from the surface. That single cut often settles whether a roof needs a coating, a recover, or a full tear-off.

When a Core Sample Gets Used

Unclear age or history — when records of past roofing work are missing or incomplete.
Suspected wet insulation — to confirm what handheld infrared cameras or moisture meters have already flagged.
Recover vs. replace decisions — when the right next step depends on how many layers are already up there.

How It Fits With Our Other Inspection Tools

A core sample is usually one step in a broader look at the roof. Drone and infrared scans and EagleView measurements identify where problems are likely; the core sample confirms what's actually inside at that spot. The cut area is patched, and the cross-section is documented through our photo documentation app so the finding is on record for you.
