When you’re managing a commercial building in Gainesville—or anywhere in North Georgia—you can’t afford surprises when it comes to your roof.
Infrared moisture surveys are one of the most effective tools available today to detect hidden water damage inside flat or low-slope commercial roofing systems.
If you’re wondering whether your building needs one, here’s what you should know.
What Is an Infrared Moisture Survey?
It’s a non-invasive scan using infrared cameras to detect temperature variations on the roof’s surface. These variations often indicate trapped moisture inside the roofing system—something you can’t see with the naked eye.
Why it matters:
Moisture inside your roof insulation can:
- Weaken the structure over time
- Lead to mold and mildew
- Decrease insulation performance
- Void warranties
- Cause premature roof failure
An infrared moisture survey helps catch these problems early—before they lead to costly repairs or full replacements.
When Should You Get One?
If you manage a commercial property, consider a scan when:
- You suspect a leak but can’t locate it
- Your roof is aging but not ready for replacement
- You’re planning a roof recover or retrofit
- You’re buying or selling a commercial property
- Your insurer requests verification of roof condition
Even if there’s no visible damage, the thermal signature from trapped water may reveal areas of concern.
Benefits of Infrared Scanning
Infrared surveys are:
- Fast — Most take just a few hours depending on roof size
- Non-invasive — No holes, no disruption to your business
- Accurate — Identifies precise locations of hidden moisture
- Cost-effective — Helps avoid tearing off the entire roof
- Data-driven — You receive documented results with photo reports
It’s the kind of preventive care that extends the life of your roof and supports better long-term planning for maintenance or replacement.
What Happens After the Survey?
If we find wet insulation, we don’t jump straight to replacement.

Common Roof Types Scanned with Infrared
Infrared surveys work especially well on:
- TPO and EPDM membrane roofs
- Built-up roofs (BUR)
- Modified bitumen
- Metal roofing with insulation below
Whether it’s a school, warehouse, church, or shopping center, this scan gives you peace of mind.
FAQs
How much does an infrared roof survey cost?
Pricing depends on the size and type of the roof, but it’s typically far less than the cost of replacing even a small section of damaged roofing. It’s a smart diagnostic tool before making big decisions.
Is infrared scanning accurate?
Yes. When performed by trained professionals under proper conditions (typically after sunset), thermal imaging can detect moisture with a high degree of accuracy.
Will the infrared camera damage my roof?
No. It’s a completely non-destructive process. No drilling, no cutting, no mess.
Can this be used for residential roofs too?
It can be, but it’s most effective on flat or low-slope systems common in commercial buildings. If you have a residential flat roof, it’s a great option.
