Do you know when you should have your commercial roof replaced? A commercial roof can last anywhere from 30 to 40 years, but this will depend on the installation process, maintenance and exposure to the elements. A new roof is a substantial, but important investment for your commercial property. The easiest way to tell if you need a new roof is to look for damage to the roof membrane. The main function of the roof membrane is to prevent water from leaking into your building. If more than 25% of the roof membranes are lifting you need to get a roofing Greenville SC professional to inspect your roof. Blistering, bubbling and warping also need to be inspected.
If your budget is limited, you could consider just replacing a section of your roof. However, if more than a quarter of the roof is damaged, it will make more financial sense to replace the entire roof. Don’t wait too long, because if the roof becomes more damaged, you can end up with structural issues. It’s a good idea to have your roof inspected every six to 12 months. If issues are discovered early, they can potentially still be repaired before you have to replace the roof. Here are six signs that you’re probably going to have to replace the entire roof.
If the roof has interior damage, you’ll notice this seeing mold starting to grow in your building, and water spots appearing on the walls. There could also be brown watermarks on the ceiling. This can also pose a health risk to those inside, so it’s best to have interior damage checked right away.
If the building smells damp and musty, it is another sign that there could be a mold problem. This could be the result of a leaking roof, trapped moisture or ponding, which is caused by large amounts of water left on your roof after storms. This is a health risk, and you should contact a professional roofing contractor to inspect your roof. They’ll be able to tell you if you should replace your roof, or if it can be repaired.
Sagging or Cracking
Your building’s roof may start to sag as a result of storms leaving behind large amounts of water. The water usually evaporates, but it sometimes stays behind. This issue can be fixed, but it will cause the roof to rot or crack if you leave it too long. If you have a flat roof, this can be dangerous for its stability.
If there is visible damage to the surface of the roof, such as gaps in the seams or large holes in the roofing membrane, you may also need to get it replaced. If you catch the issues early enough, you may be able to get away with only having repairs done. Trapped moisture and air can cause bubbles to form, which could thin the layer of the membrane. It’s best to have your roof replaced if there are bubbles and blisters all over its surface.
High Energy Bills
If your energy bill has shot up, it could also be an indication that your roof needs to be replaced. If the roof has leaks or cracks, air will enter the building and your HVAC system will have to work harder to heat or cool it.
An Older Roof
If your roof is already older, or approaching its average lifespan, it’s time to start thinking of a replacement. Ask your local roofing contractor to do an inspection and determine what your options are. Often, installing a new roof can improve the building’s energy efficiency and save you money in the long run.
A commercial roof can last you a long time if you have regular maintenance done. If issues are found early enough, you could still have the roof repaired. As time passes, it becomes more likely that you will have to replace the entire roof. A roofing contractor will be able to provide you with advice and recommendations if you are not sure how to proceed.
