Our team is trained in thermal (infrared) imaging and verifies what the camera shows with cores or moisture probes.
How it works
Wet insulation holds heat longer than dry insulation. After a sunny day, as the roof cools in the evening, wet areas show up warmer on a thermal camera. The industry practice for this method is ASTM C1153, the standard practice for locating wet insulation in roofing systems with infrared imaging.
- Scan on a suitable evening. Results depend on weather: a dry roof surface, a sunny day and a clear evening.
- Mark the anomalies on the roof and on a roof plan.
- Verify with cores or moisture probes, since not every warm spot is water.
- Report with thermal and regular photos, wet-area sizes and repair options.
When it helps
- Deciding between repair, coating, recover and replacement (most coatings and recovers shouldn't go over wet insulation)
- Before buying a building
- After a storm or a long-running leak
- Ahead of a warranty or maintenance program
Infrared works best on low-slope roofs with absorbent insulation. Some roof types and ballasted roofs don't scan well; we'll tell you if yours is one of them.
Who we work for: Blake consults for insurance carriers and for building owners, and takes appraisal and umpire assignments for both carriers and policyholders, on residential and commercial property.
Ask about a consulting engagement or call (817) 733-9228. Tell us the property type, roof size and what decision you need to make, and we'll tell you what kind of report fits.
