While many commercial buildings have a flat roof, others choose a low-slope roof. Our Atlanta commercial roof pros know that, regardless of what type of roof you have, damage can and will occur over the years. What are the most common causes of damage to low-slope roofs?
Considerable fluctuations in temperature. While temperatures may rise during the daytime hours, they can drop drastically at night. This constant change in temperature results in expansion and contraction, which can stress the roof, putting strain on seam adhesions, flashings, and more. Often referred to as “thermal cycling,” this type of damage is gradual and can be prevented through regular maintenance.
Contact with damaging materials. Many restaurants use oil or grease in cooking, which can leak from the vent or even spray onto the roof if the vent becomes clogged with grease. With any type of roof, including the low-slope variety, grease can work to gradually dissolve the membrane. Another example of incompatible materials is with metal roofs, which can develop rust spots when they come in contact with other metal objects such as a nail, screw, or other tool used by an HVAC technician or someone else working on the roof.
Lack of maintenance. As long as you don’t notice any leaks inside your building, it’s easy to forget about the roof. You’re never on it, and therefore give little thought to it. Because it does protect the integrity of the structure and everything inside your business, regular maintenance is vital. Simply put, having your roof inspected and maintained on a regular basis can help you ward off costly damage and extend the life of your roofing system.
Improper installation. You assume when a roof is installed that the contractors know what they’re doing, but this isn’t always the case. Unfortunately some companies take shortcuts (or, in some cases the client tries to save money by going the cheapest route possible, resulting in sub-par work). Having your low-slope roof installed correctly by professionals who know the importance of proper drainage, the right pitch to move water to gutters, and other aspects of installation is critical.
