How much roof area can an infrared scan cover in one night?
A single surveyor can cover 20,000 to 40,000 square feet in a 90-minute survey window under good conditions. For larger roofs — the distribution centers and logistics facilities in the Rickenbacker corridor that run 100,000 to 400,000 square feet — we schedule multi-night surveys or use two surveyors to cover the area in a single night. The thermal window is fixed by daylight and ambient temperature, so scheduling is time-sensitive.
Can infrared scanning be done on any type of commercial roof system?
Infrared scanning works well on TPO, EPDM, PVC, and modified bitumen single-ply and multi-ply systems where the insulation layer is immediately below the membrane. It is less effective on ballasted systems — the river stone ballast absorbs and retains heat differently than membrane, making the thermal differential harder to read. For ballasted roofs, nuclear moisture testing is typically more reliable. We assess the roof system type before recommending an infrared survey.
Do you provide the thermal images themselves or just the interpretation?
Both. The deliverable includes the moisture distribution map (the interpreted output), the raw thermal image archive referenced to the roof zone diagram, the anomaly log with core validation results, and the survey conditions documentation. Building owners who want to share the raw thermal images with their own engineers or consultants receive the full archive in standard image format.
