Thermal Image Scans for Flat Roof Leak & Moisture Detection

Thermal Image Scans for Flat Roof Leak & Moisture Detection –

If you have a leak on a new to mid life flat roof and have been told that a new roof is needed, then call us first. We may be able to save you a substantial amount of money. Thermal imaging can be used to detect the precise location of the leak and mark the affected area so that repairs can be made to the leaking area. Obviously, if the roof is older then you should forgo the thermal imaging and invest in the needed new roof.
If your flat roof is under Warranty; that is the best time to get it inspected. Most problems are related to human error and can be minor and easy to repair when caught early on. Since it is still under Warranty; the roofer should fix these problems with no extra cost to you.
More than 50% of flat roofs leak with in the first year alone. Depending on the construction type of your roof; you will not even notice water leaking from the roof. You will notice when the water corrodes or rots the roof and at that point you will have some major problems. That is why we recommend surveying your flat roof once a year, so that if a leak occurs it is detected before it can do a maximum amount of damage.
Even if the roof already has major problems Thermal Imaging can still be a benefit to you. We can identify the problem areas and instead of having to get a whole new roof, which is what the roofers will almost always recommend of course, we can isolate the specific areas that need repair.
Understand the theory of IR roof inspections
Normally there is little or no water within a flat roof assembly. When a leak develops, water enters the assemble and depending on the type of insulation system is either absorbed by the insulation or runs to the cracks between the nonabsorbent insulation. When water enters the roof assembly it is there for a long time. Accelerated testing has proved that once wet, a flat roof will not dry out during the life of the roof, even if there is never another leak.
Thermal capacitance is the physical property of a material’s ability to store heat. The materials in a roof assembly have relatively low thermal capacitance, especially when compared to water. Water requires a lot of energy to raise its temperature and likewise must release a lot of energy to cool down.
This is the basis of thermal roof inspections: dry roof insulation will heat up quickly when heated by the sun, while wet roof insulation will heat up slowly. Later in the day, after the sun has gone down, the roof starts to cool off. The dry insulation cools down quickly while the wet insulation cools off slowly. When the dry insulation reaches a temperature cooler than the wet insulation, the thermographer can see the wet areas as warmer.
