Roof Moisture Detection Services

Thermal Imaging Analysis for Roof Evaluations

Class A Roofing Consultants provides thermal imaging and aerial thermal imaging technology to locate moisture in the roofing system and in the building interior. A thermographic flat roof survey is used to locate and identify moisture-laden areas within the roof substrates.

What Does Thermal Imaging Show?

What Does Thermal Imaging Show?

Since the infrared imaging system will identify any temperature variations (thermal anomalies) on a flat roofs surface, verification of moisture must be made in order to avoid false anomalies. Therefore, we use non-destructive electrical impedance scanners, to verify our findings. We also use roof and wall scanners, concrete moisture meters, humidity probes, and an infrared surface thermometer to complete our moisture surveys. Additionally, core cuts can be done too if needed.

Roof Moisture Detection Mapping

We offer thermal capacitance testing and mapping of the moisture trapped in your roofing systems. The Tramex Dec Scanner detects and evaluates the moisture conditions within roofing systems by non-destructively measuring the electrical impedance. A low-frequency electronic signal is generated, transmitted into the material under test via one of the two electrodes incorporated in the rubber electrode mat, and received by the second electrode. The strength of this signal varies in proportion to the amount of moisture in the material under test. The Dec Scanner determines the strength of the current and converts this to a comparative moisture content value. By moving the Dec Scanner across a roof surface in a regular pattern, a continuous reading is obtained, and areas that contain moisture can be readily identified.

Why Use Moisture Detection for Roofs?

Why Use Moisture Detection for Roofs?

Class A Roofing utilizes thermal imaging, aerial thermal imaging technology and thermal capacitance testing for roof evaluations to:

  • Uncover problems that cannot be identified visually
  • Not disruptive to roof system

Your Class A Roofing Team 40 Years of Proven Performance

Duro-Last® Roofing has been manufacturing single-ply membrane for Oregon flat and low sloped roofs since 1978. Duro-Last® Roofing started in Saginaw, Michigan. Due to our rapid growth a manufacturing plant was needed in the west coast. Over 30 years ago Duro-Last® opened in Grants Pass, Oregon. Since 1987 we have been manufacturing our custom fabricated roofing and edge metal right here in Oregon. Class A Roofing Consultants, located in Portland, are our independent sales representatives for Oregon. We have over 70 highly qualified contractors installing roofs in Portland, Eugene, Salem, Roseburg, Medford, Brookings, Coos Bay, Tillamook, Astoria, Bend, Hood River, The Dalles, Pendleton and every city in between.  Please call us today to receive a free roofing estimate from an authorized roofing contractor.
