Despite sharing the same purpose, to protect your building, commercial flat roofs share very little in common with their residential roof counterparts. To begin with, residential roofs are pitched to allow for water runoff. Generally speaking, the function and needs of flat roofs are much different from those of a pitched residential roof. Like residential roofs, however, there are several main reasons a commercial flat roof might be leaking.


When a rubber membrane springs a leak, the flat roof repair pros at A-Plus Roofing use infrared technology to locate the source of the problem and make a complete repair. In this blog entry, our team shares some of the top reasons behind a commercial flat roof leak and talks about what we can do to help.


Here are a few main causes of leaks we see during roof inspections:


1.      Overlooked Maintenance- A well-maintained flat roof is incredibly durable and capable of standing up to the test of time. But when regular maintenance is overlooked on a commercial roof, you can expect to see problems that will compound over time. Wind, snow, ice, and rain can cause a roof’s protective gravel layer to shift around. Additionally, minor damage can become significant when strong storms or weather come along.


2.      Natural Elements- Rain, storms, hail, and temperature extremes are all common here in the Midwest. In addition to the damage caused by freeze and thaw cycles, debris like tree limbs and rocks can impact your roof and cause trouble. In many cases, this type of damage will be covered by the company’s insurance. In some instances, a roof may need to be completely replaced.


3.      Sealant Problems- Both residential homes and commercial facilities require chimneys and exhaust pipes to allow the release of gas from their heating and plumbing systems. Unfortunately, these spots represent a break in the roof membrane, creating a potential vulnerability. The seals around them will require updating and replacing eventually. That’s why it’s important to inspect exhaust vents for pipe sealant problems on an annual basis.
