Mr. Jeremy Pope Beaufort Engineering Services Inc 2712 Bull St Beaufort, SC 29902

Dear Mr. Jeremy Pope:

The building roofs of the 215 Perry Hill Rd building at “Montgomery VA Medical Center” in Montgomery, AL 36109 were the subjects of an infrared (IR) survey on the night of 5/30/223. The day weather was mostly sunny and approximately 83F degrees post set conditions clear skies and 80-73F degrees providing good infrared imaging.

This report includes:

RoofScanIR™ digital report printed in high resolution with explanations of the method, Conditions at the time of the survey, A map marked with the finding locations, Individual report pages of all suspect wet areas.

BUILDINGTECH INSPECTION SERVICE, LLC, an Authorized RoofScanIR™ Contractor, was retained for an infrared survey of the roof in an effort to identify areas of suspect moisture and to mark the areas for further review.

This report is based on information obtained at the site at the given date and time. We marked an outline of identified areas of moisture with marking paint directly on the roof and documented our findings with a thermograph and photograph of the Area. The purpose of any infrared thermography service is not to locate or identify leak sources. Our inspection is designed to comply with INFRASPECTION -"Standard Practice for Location of Wet Insulation in Roofing Systems Using Infrared Imaging" with the exception of core sampling.

This report is for the exclusive use of our Client and is not intended for any other purpose. The report is based on the information available to us at this time as described in the report. Should Additional information become available at a later date, we reserve the right to determine the Impact, if any, the new information may have on our discovery and recommendations and to revise our opinions and conclusions if necessary and warranted. Some anomalies were verified by using a none destructive moisture meter check the moisture content. There may specific Areas and items those were inaccessible during our survey. We can make no representations regarding conditions that may be present but were concealed or inaccessible during the survey. With access and an opportunity for inspection, additional reportable conditions may be discovered.

Inspection of the inaccessible areas will be performed at an additional cost after access is provided.

Invasive Verification of infrared data is the responsibility of others and is not included in the below price.

BUILDINGTECH INSPECTION SERVICES, LLC does not perform any construction activities or repairs. Noninvasive testing equipment such as nuclear and capacitance meters may be used to compliment, but not replace invasive verification. The client shall verify the data & must be carried out by the following invasive test methods: cores, or Cores and moisture meter probes by a qualified roofer.

Analysis and Recommendations We recommend that your roof maintenance team carefully review this report. Then, with reference to the images contained herein and the marked areas on the roof, these areas should be physically located and given a thorough visual examination. When warranted, these areas should be subjected to a destructive test (core sample) to confirm the analysis. We recommend a roofing profession conduct core samples on the roof(s) as needed. Destructive probes and roof cores will be taken and repaired by others and are not in this scope of our work. Services such as interpretation of thermal patterns documented in this report and any remedial and replacement recommendations should be performed by a knowledgeable roofing consultant or comparable roofing expert.

Our reports are designed to be clear, concise and useful. Please review it carefully. If there is anything you would like us to explain, or if there is other information you would like, please feel free to call us as we would be happy to answer any questions.

Sincerely, John Gutierrez

Understanding Building Roof Infrared Imagery

Infrared imagery is often a grayscale picture whose scales (or shades of gray) represent the differences in temperature and emissivity (opposite of reflectivity) of objects in the image. As a general rule, objects in the image that are lighter in color are warmer, and darker objects are cooler. No object in the images is detected via visible light wavelengths (400-700 nanometers) rather, only from infrared wavelengths in the 3000-5000 nanometers or 8000-14000 nanometers range. Lights and other relatively hot objects are very evident, but as a result of their heat…not light emissions. When an image is taken with an infrared camera, it is often recorded onto videotape and/or digitally saved to an on-board storage device. The image may be then modified in a number of ways to enhance its value to the end user. Imager files are digitized, saved and converted to jpeg images, then adjusted for color, contrast and brightness before being scaled and placed into a report file. Report files are then saved in high quality PDF format for the client use.

During the day, the sun radiates energy onto the roof surface and into the roof substrate, and then at night, the roof radiates this heat back into outer space. This is called radiational cooling. Areas of the roof that are of a higher mass (wet) retain this heat longer than that of the lower mass (dry) areas. Infrared imagers can detect this heat and "see" the warmer, higher mass areas, during the "window" of uneven heat dissipation.

We scan the roof with sensitive infrared cameras to detect the sources of heat and record them for later, analysis. Since we can “see” all areas of a different mass immediately, we can then mark the roof and/or save infrared images for report use.
