Infrared Roof Inspection Explained: Seeing the Invisible
By Roof Inspection Masters • New Brunswick, NJ
Some leaks have no visible source. Infrared roof inspections find them by reading heat — revealing trapped moisture that visual inspection cannot see.
How it works
After a sunny day, dry roofing cools quickly at dusk while wet insulation and saturated decking hold heat longer. A thermal camera renders these temperature differences as vivid patterns, mapping moisture with remarkable precision. We verify every anomaly with moisture meters or core samples — the camera finds suspects, physical testing convicts.
When it is the right tool
Mysterious interior stains with intact-looking roofing, flat and low-slope roofs with unknown membrane condition, verifying a leak repair actually worked, pre-purchase due diligence on large or commercial roofs, and recurring leaks that standard repairs never solved.
When it is overkill
Obvious visible damage — missing shingles, torn flashing — needs no thermal camera. Infrared earns its fee on hidden-moisture puzzles, not clear-cut damage.
Why It Matters in New Brunswick
New Brunswick averages about 29 inches of snow per winter with February nor'easters, ice dams from freeze-thaw cycles, and humid summers. Snow load, ice damming and wind-driven rain are the big three roof killers here. An inspection catches the small failures — lifted flashing, cracked boots, clogged valleys — before they become interior damage. At $150 to $400, it is the cheapest roofing decision most homeowners ever make.

Frequently Asked Questions
Very, when done under proper thermal conditions and verified with meters or cores. Unverified thermal images alone are not a diagnosis.
Typically evening after solar loading — the cooling differential reveals wet areas. Conditions matter more than clock time.
Yes — it maps trapped moisture under shingles and tile, especially in valleys and around penetrations.
