You may be wondering if your commercial roof needs to be replaced. This can be a tricky question to answer if you are unaware of certain signs or facts. Luckily, we know all the signs that you should look for to determine whether you’re due for a commercial roof replacement. The last thing you want is a roofing emergency when prevention could have saved you time and money.


Commercial Roof Age

Before you go and spend a bunch of time inspecting your roof, one of the most important pieces of information that you can know is how old your commercial roof is. Depending on your roofing materials, you can expect a commercial roof to last anywhere from 10-40 years. That is a pretty wide margin but take away metal roofs (which last much longer) and you should start thinking about a commercial roof replacement after around 20 years. If you know that your roof is old, then it would be wise to have a professional inspect it and see if a replacement is necessary.


Commercial Roof Damage

Once you confirm the age of your roof, you should start thinking about any damage that you remember or that you have seen. Different types of damage can mean different things and solutions for your commercial roof, but if you notice increased frequency or significance then it may be time to replace it.


There is nothing more annoying than looking up and seeing a dark spot on the ceiling tiles while you hear the faint clap of water hitting the carpet. As common as leaks are, and as numerous as their causes can be, the possibility of roof damage should always be a concern, especially if leaks become frequent and severe. This can either indicate faulty flashing or damaged roof membranes that if allowed to persist, can end up causing significant damage.

Damaged Roof Membrane

Leaks can oftentimes be caused by damaged roof membranes, but if there is no rain, then you may have damage that you are unaware of. A damaged roof membrane can lead to bubbles, which is trapped air underneath the membrane that if left unchecked, can lead to significant damage that requires a roof replacement.

Water Ponding

This problem may be more obvious to you if you are assessing your commercial roof. Water Ponding is defined as water that has been stagnant on a flat surface for more than 48 hours. This can happen for several reasons, such as improper installation or draining issues, but can quickly become a serious problem. Ponding water on your roof can lead to increased stress on your roof membrane, causing a collapse if severe enough. It can also cause rot which can be difficult to repair.
