Flat roofs are the best roofing solution for commercial buildings because they allow for an easier installation over a larger surface area. However, like all parts of a building, flat roofs will begin to break down over time as they age and experience stress and wear. A flat roof that fails can allow water into your business, which can cause a great deal of water damage and promote mold and mildew growth, both of which are expensive and complicated to fix. Thankfully, there are a number of things that you can keep your eye out to determine when it's time to contact a roofing services professional and have your flat roof repaired before it fails.
If you notice that there is any amount of standing water on your flat roof, you should contact a professional immediately. This indicates that there is a drainage problem on you roof: some flat roofs have slight slants or drainage systems that ensure that no water is able to pool on them for an extended period of time. Pooling water can cause a number of problems and can quickly degrade the material of your roof.
Any signs of corrosion on the components of your roof, such as on the flashing or on the nails, indicate that your roof has seen a great deal of weather exposure and is becoming worn. This is a normal occurrence that happens with age, but it should be addressed as soon as possible, as corrosion can cause these components to degrade and provide openings for water to enter the building.
Missing Nails and Flashing
In a similar vein to the above point, you should inspect the components of your roof to determine if any are missing. Flashing is found around roofing installations like vents and fans, while roofing nails can be found across a flat roof. While it's unlikely that components will simply be torn off through everyday weather conditions, it's a good idea to check after storms and periods of intense weather to see if anything has been ripped away.
Also known as air pockets, roof blisters refer to when air or water becomes trapped between your flat roof and the sealing material, usually a rubber sheet or barrier. If you notice that a multitude of these blisters are present on your roof, you should contact a professional immediately instead of trying to pop or fix them yourself, as they can cause tears and rips into the roofing material that provide an entrance for water to enter your home.
