Flat roofs wear out due to sun damage, surface temperature, hail, snow, storms and other reasons. Other common problems with flat roofs are shifts caused by expansion and contraction due to varying temperatures. Small damage in the roof can lead to structural damage, which can turn out to be very expensive. We also advise focusing on regular maintenance and inspection of roofs to identify any potential threats. Regular inspection can help mitigate costly repairs by identifying and fixing the issues on time. Examples of common commercial flat roof problems include:

• Leaks: Weather damage or aging of your commercial flat roof can result in leaks entering your building and leading to more damage.
• Ponding: While flat roofs have a degree of sloping to allow water to run off, it might not be adequate due to improper installation or wear and tear. Rainwater that pools on a roof can cause it to sag. Ponding water freezes, and the expansion damages the flat roof membrane.
• Structural movement: Structural movement is the contraction and expansion of a building’s envelope. This natural process causes movement in the building and the roof over time. In commercial properties, the inside temperatures tend to be acutely different from the outside temperatures due to the quality of commercial-grade HVAC equipment. This difference accelerates the structural movement, causing flat roof membranes to crack around flashing details, drains, scuppers, and field seams.
• Splits and tears: Flat roofs are prone to developing cracks and tears due to extreme weather conditions. This is why it is essential to have our commercial roofers examine damages to your roof after a storm. Ignoring these punctures can cause them to worsen, which can turn into leaks.
