There’s a different inspection process for each roof. If you’re doing a preliminary roof inspection, you should always start with a roof’s most vulnerable parts.
UV Protection Features
You should start with the flat roof membrane, which would normally be ultraviolet(UV) resistant. That’s because due to their low slope, flat roofs are more exposed to UV rays, which can quickly break down the roof surface. The form of UV protection varies depending on the type of flat roof.
For example, built-up roofing (BUR), composed of interlaced layers of fabric and asphalt, has a layer of gravel embedded into its surface. If too many granules have been dislodged, bald patches will start to appear.
Modified Bitumen Roofing
Modified bitumen roofing also has a layer of gravel embedded in it. But you should watch out for pooling water. That’s because even among flat roofs, modified bitumen sheets are particularly vulnerable to moisture damage. If puddles are forming, make sure the drains aren’t clogged.
Sealants and flashing are used to close seams and gaps in an ethylene propylene diene terpolymer (EPDM) roof membrane. However, UV rays can weaken the adhesives used to seal the seams, causing the flashing to detach itself from the seams.
Check the membrane for holes as well. Wear and tear from foot traffic as well as sharp object can easily puncture the EPDM membrane.
Keep in mind that the early signs of roof damage are usually subtle. As such, you still need to hire a contractor to do a comprehensive roof inspection. Just make sure to hire a qualified one.
