If you want to know when your commercial roof is at the end of its life, you need to know what to look for. In some cases, the signs can be crystal clear to you, while in others, you may need to know a little bit more before you make a decision to replace it. Fortunately, when the roofing does need to be replaced, you will see signs of the following:

  • Cascades of water can be found when you enter into the buildings storage area.
  • You can see the sunlight shining through without stepping outside.
  • Part of the roofing system is collapsing and shingles are falling off the roof.

Even though there are obvious signs that you can see easily, there are other signs that may not be so apparent. Here are 4 of the most uncommon signs that are provided for you below.

Cost of the Energy Begins to Rise

One end of roof life sign that may not be so apparent is the cost of the energy bill rising. Since the air conditioning and heating systems tend to run harder when the roofing is bad, the differences can be felt in the pocket. For instance, because the roof is a big part of the insulation that is needed for the home in both winter and the summer, you may struggle with the end of your roofing’s life before you actually identify the actual problem.

Bubbles and Blisters

Though there are several non-obvious signs of the roofing systems end of life, there is at least one that can be seen if you are at the right position. If you are standing on the roof or someone that is near this area, you can expect to install a new roofing system if you see a number of issues that stand out. For instance, you may see bubbles in the roofing materials that are usually causes by liquid being trapped on the inside of the deck and the membrane. Also, if you see micro cracks, you may see various kinds of blisters.

Dirt Rings and More

Inspecting a commercial roof for damages is not done haphazardly by just anyone. Due to the fact that many commercial roofs are several levels up, a professional roofer will need to know what to look for. For instance, if you want to hire a professional to inspect your commercial roofing to determine how long it will last before it needs to be replaced, they usually make their recommendations based on the puddles that are left behind after it rains. For instance, in some cases, it is not uncommon to see lots of dirt rings, fungus and algae remaining on the top of the roof.

Ticking Clock Signs

Once a commercial roof has been installed on a building, you should keep good records on the dates and other associated factors. This is because each roof has an estimated life expectancy which needs to be taken into account. For some roofing systems, the lifespan is 20 to 30 years, while others may have a life expectancy of 50 years. Whatever the case, you should also make sure that you have the roof inspected annually for problems.
