Preventive Maintenance for commercial roof's can be the most inexpensive way to save money.

Walk on or aerials we conduct the most accurate technology in the industry to survey your roof. Even experience roofing companies may fall short on seeing what is underneath the top layer. Pin pointing leaks, checking for hidden moisture is very difficult with out using infrared.

Many roofs need to be replaced prematurely due to moisture damage from leaks and improper  installation. Infrared (IR) thermography has a proven track record in finding damaged portions of roofing structure so they can be repaired before water damage rots your whole roof. Thermography is a non-contact testing method. Flat Roofs, Tar, Shingle, Metal, Shake or membrane. 1000 sq' to several million sq'. Any project any place. Give us a call.

These aerial inspections were conducted by helicopter.  The blue blotches on the roof show water under the membrane.

This roof was dry during the inspection. As you can see this roof has a great deal of issues.

It is difficult to schedule, perform and write a report for a Roof Moisture Survey. Even if a company is getting good money for a survey, roof surveys are often difficult jobs, even for a professional thermographer. Even with the image quality, portability, handy image storage capabilities, improved software and computerized reporting systems of the latest IR cameras, the logistical considerations of the job and thermal dynamics of a roof structure make it a tough job to perform well. Also, there are many different types of roofs, membranes, fastening systems, substrates and insulations that are used to construct the roof system, which have to be considered. However because of the experience and type of camera we use, this roof survey turned out great!

Very little time is required to obtain the infrared data, once the aircraft is over the building. Usually, a 200,000 square foot building is imaged in less than 20 minutes. This will include multiple passes over the building from varying altitudes, attitudes, speeds and angles.

There are roofing companies that own there own thermal camera and conduct roof surveys. But some of them have never been certified or trained. Then most of them purchase a thermal camera that does not have the quality to produce accurate surveys. The mis conception is: People in general wanting to get into this area of technology see the benefits of thermal imaging and think they can simple jump into it. They think they can purchase a low end thermal camera for around $ 16,000.00 then point & shoot. Wrong.

 Aerials of under ground steam lines. The darker red colors show heat under the road. As you can see the heat is

not running in a straight path from the sides. This is an indication of a leaking 6 inch line 6 feet underground.

In the center of the red image see how it is spreading out.

 The red colors show the under ground steam line. This line is 6 feet under ground. The red image in the grass

area is a underground leak.

 Most modern infrared cameras have 256 X 256 pixels, a total of 65,536 pixels. The infrared cameras that we use for

Aerial IR have 640 X 480 pixels, which total 307,000 pixels high definition.

While the light blue is normal.
