Built up roofs (BUR) are dark colored roofs which can reach a scorching 180°F in the summer. They are made of tar or asphalt which dries out,
becomes brittle and cracks. Leaks are difficult to find.

Concrete roofs are porous and absorbs moisture. Moist concrete promotes rebar corrosion which causes structural damage. Uncoated concrete roofs
absorb solar heat in the daytime & slowly release it at night.
|
|
Metal roofs do not have to be old and rusted to leak. A high pitched metal roof is just as prone to leak as a low sloped one. Roof patches and
other temporary fixes can aggravate the leak.

Modified Bitumen roofs need to be coated if noticeable granule loss occurs. Don't wait until you see crazing, cracking or blistering. Ponding
conditions accelerate defects.

|
Polyurethane spray foam is not UV-resistant and starts deteriorating as soon as it is installed. Elastomeric coatings block harmful UV-rays and provides a seamless, watertight membrane.

|
Single ply roofs like Ethylene Propylene Diene Monomer (EPDM), Thermoplastic Polyolefin (TPO), Polyvinyl Choride (PVC) and Hypalon roofing become
brittle over time.
