Infrared Roof Moisture Detection in Texas
Some low slope roofs can develop problems in as little as one to two years. Low sloped roofs have a slight pitch to allow for drainage. These roofs are composed of a structural deck with an insulation and a waterproof membrane on top. An on roof infrared moisture survey is a very economical method to determining the state of your flat roof.
The damage from a leak in the membrane can be at a minimum a nuisance inside the building but the damage to the roof from the trapped moisture can be very costly. When the moisture enters the roof and becomes trapped it can cause damage and possible failure of the roofing system. Locating the wet insulation with an infrared roof inspection the wet areas can be removed and replaced and the life expectancy of the roof will be increased. This is a great cost savings to the owner of the building as only the wet problem areas will be repaired. A roof moisture inspection completed with a thermal camera is nondestructive.
Benefits of an Infrared Roof Survey:
- Detect moisture in insulation quickly
- Eliminate replacing good portion of roof
- Extend the life of the roof
- IR scans are non-destructive
- Reduce maintenance cost
- Verify absences of moisture after recover for warranty
How Thermal IR Roof Scans Work
The thermal capacitance of wet insulation is much higher than that of dry insulation. Therefor on an evening following a warm sunny day the roof will cool somewhat rapidly. This cooling of the roof will leave the areas of wet insulation warmer and easy to spot with an infrared thermal scan.
During the roof inspection at night these areas of moisture can be marked for confirmation or removal. The length of time on the roof to perform the infrared survey depends on the size of the roof and the number of indications found. If the conditions are good the window of opportunity to scan can last for a number of hours. The surface of the roof must be dry and clear of any debris.
Here is a list of some roofs that are candidates for IR scans:
- Asphalt Built-up
- Coal Tar Built-up
- Slag Embedded on Built-up Roof
- EPDM Mechanically Attached with In-Seam Batten Bars
- Pea Gravel Embedded on Built-up Roof
- Granule Surfaced Modified Bitumen BUR
- Smooth Surfaced Modified Bitumen BUR
Gravel should be less than ½” in diameter and less than 1” thick.
Here is a list of some insulation types that are candidates for IR scans:
- Wood Fiber
- Cane Fiberboard
- Some Polyisocyanurate
Why Advanced Infrared Roof Scan Service?
We provide detailed, high-quality and easy to understand certified infrared inspection reports that thoroughly documenting our findings.
If your plans are to install solar panels on your roof it is a good idea to scan your roof before installation so you can make any repairs before.
If you need an infrared roof moisture survey in Houston, San Antonio, Dallas, Austin, Fort Worth, Corpus Christi, Laredo, Lubbock, Amarillo, Brownsville, Midland Odessa, Waco, Sugar Land, The Woodlands, Tyler, College Station and Abilene or anywhere in Texas we can help.
The infrared images above were taken with a FLIR camera.
We outline identified areas of moisture with marking paint directly on the roof and take both infrared and digital photographs of the area. Our inspection is designed to comply with ASTM Standard C1153 -“Standard Practice for Location of Wet Insulation in Roofing Systems Using Infrared Imaging” with the exception of core sampling.
