Residential and Commercial Flat Roof Inspections

One of the great uses for thermal infrared technology is to detect moisture problems in your residential or commercial flat roof. Flat roofs are particularly vulnerable to roof leaks caused by improper drainage and standing water. These leaks get into the insulation where it is trapped. This leads to damage to the roof structure. Many find that by repairing these areas before they become a big problem saves time and money by extending the life of the roof. By measuring very small differences in surface temperature, a thermographer can point out problems that are not visible to the human eye.

Flat Roof Inspection Process

During the daytime, the sun heats up the roof surface. After sunset the roof surface begins to cool, releasing the heat accumulated during the daytime. If there is a leak in the roof, the roof structure will become wet. This creates a higher thermal mass in the wet areas than in the rest of the structure. The infrared camera will be able to detect this moisture from a clear picture of the damaged area. Because of the technical work involved, a professional should be used to detect a flat roof leak using infrared survey.

Roofs are damaged daily because of heat, water, and improper maintenance. Many damaged area cannot be located until it is too late to repair the problem. Regular checks should be done to search for leaks, cracks, rotting or other damage. If left untreated, these problems can lead to the entire roof needing to be replaced. This is not necessary if proper maintenance is done, including the use of infrared survey to find a flat roof leak. Flat roofs are especially vulnerable to water damage because there is no roof slope for the water to flow to. Often, water will pool in one area of a flat roof and begin to weigh down the structure, which will cause leaks and other structural problems. The areas of moisture can quickly be identified using an infrared survey.

Flat Roof Infrared Inspections – What We Do

Measure The Roof – We will visit your site to measure the roof area and access the situation to determine a time suitable for the inspection. Ideally the roof should be inspected on the clear evening approximately 1 hour after sunset where there has been plenty of plenty of sunlight throughout the day. An infrared inspection can be conducted after a heavy overcast day provided the outside temperature is at least 19 degrees colder than the space directly under the roof deck for the 24 hour period leading up to the inspection. The roof ideally should have minimal to no standing water. This is sometimes simply unavoidable. The wind should be less than 15 mph during the day and during the inspection process. There should have been no rain in the 24 hours leading up to the inspection.

Infrared Scan – We scan the entire roof surface providing you with Thermograms and digital pictures of the areas being noted.

Verify Finding – Through the use of a moisture meter, we verify and document the moisture content of the documented area. In the event the moisture meter can not accurately verify finding, 2 core cut samples of the roof area may be taken. In the event core samples are taken these locations will be documented for quick reference.

Mark the Wet Area – We mark the areas be documented and marked with spray paint to clearly identify the areas of moisture penetration for repair.

Written Report – We provide you with a written report of the findings along with a scaled drawing showing the locations of the wet areas, thermogrmas, and digital photos.

What To Do After a Flat Roof Repair or New Installation.

After a flat roof repair or new installation has been made, we recommend that a second inspection be made approximately 2 months after the flat roof repair or new installation to verify the problems have been resolved. Afterward it is recommended that an inspection be done annually to extend the life of your roof by catching any moisture problems before they become severe.
