Most commercial roofing systems are designed to take a beating, but the roof is far from being indestructible. Therefore, certain kinds of roofing problems, like the ones on our list, have to be addressed by your trusted commercial roofing contractor as soon as possible.
Alligatoring – This typically happens in asphalt-based roofing materials, such as built-up roofing (BUR). As the top surface shrinks due to temperature changes, cracks develop and turn into what looks like alligator skin, hence the name. While shrinkage happens over a long time, alligatoring has to be addressed as soon as possible; the cracks could split the membrane and expose the layers underneath to water exposure.
Torn Material at the Ridges – Another common problem with BUR roofing is the tearing at the ridges. Thermal expansion, combined with the insulation layer separating from the roof deck, creates undue stress in these areas, which causes the outer material to tear. The sooner these issues are addressed, the less repair work required.
Punctures – Single-ply roofing is susceptible to punctures from sharp, pointed items, constant foot traffic, or pointed airborne debris. Such punctures can allow water intrusion that will lead to bigger problems down the line. Fortunately, TPO and EPDM roofing are both designed to be easily patched. In addition to providing exceptional commercial construction services, Allied Construction Services has extensive knowledge of addressing commercial roofing issues, including locating small punctures and patching them up before they get worse.
Seam Failure – Roofing seams on single-ply roofing can be sealed using adhesive or heat-welding depending on the material. Seam failure is often caused by installation errors that allow gaps, which, when exposed to high winds, can easily get torn apart. Shrinkage or poor adhesive can also be the cause and it’s important to correct this problem as soon as it’s spotted. Just like punctures, failed seams can allow rainwater intrusion.
