Flat roofs are ideal for commercial buildings for many reasons, and in a previous blog, we went over several of the reasons why flat roofs are such great options for businesses. However, since flat roofs are flat, they have their own unique challenges and problems that all business owners need to be aware of. At Nationwide Developments, we believe that knowledge is power, and that, the more you know about specific roofing problems, as well as how to take proper care of your roof, the better you’ll be able to take care of it. That’s why our commercial roofing experts in Hilton Head have come up with this list of the most common flat roof problems.
#1. Moisture Build-Ups and Leaks
This has to be the most common problem with flat roofs because there’s no clear way for water to escape from a roof that has no slope, and it often ends up simply seeping into the roof. Lingering moisture build-ups should be dealt with promptly, as they can easily lead to leaks, mold growth and other issues.
#2. Pooling Water
Over time, your commercial building can slightly shift or settle, which leads to a roof that is not quite as level as it was at the time of installation. This makes it possible for water to start pooling in the dips and divots of your roof when it rains. If pooling water is left too long and is allowed to seep into your roof’s lower layers, it compromises and deteriorates your roof, shortening its lifespan.
#3. Flashing Issues
When the weather changes and the temperature shifts, it can cause your commercial roof to contract and expand. The flashings that protect the corners and edges of your commercial roof from leaks will start to pull away from your roof. Replacing flashings at the first sign of trouble can ensure that your roof gets the moisture protection that it needs, but if the problem is left for too long, you may end up needing a whole new commercial roof.
#4. Buckling in the Membrane
Most flat roofs are constructed with a single membrane that is laid across the roof. As we stated above, over time, your building will settle and shift, and since the membrane is a single piece, it can buckle when your roof shifts. Not only can a buckling roof membrane lead to extensive problems down the road, but it can make it unsafe to operate under.
#5. Roof Cracks
Because a flat roof is flat, it has to contend with a lot more pressure than a sloped roof. If the pressure becomes excessive, it can lead to cracks in your roof. When cracks appear it your flat roof, it’s imperative that you get immediate assistance, as a crack can often indicate that your roof is structurally compromised.
These are just a few of the common flat roof problems, but you’ll be glad to know that, with regular maintenance and inspections, you can avoid many of them. If your commercial roof is due for service of any kind, give the experts at Nationwide Developments a call today.
