A roof is a big investment. It protects your home or business from the elements and can last for decades with proper maintenance. However, there will come a time when every roof needs to be replaced. So, how do you know when it’s time to replace your flat roof? Keep reading for everything you need to know about when to replace a flat roof.

How Long Does a Flat Roof Last?

A flat roof can last anywhere from 15 to 30 years, depending on the type of material and the quality of installation. However, most flat roofs will need to be replaced sooner than that due to ponding water, which we’ll discuss in more detail later.

Signs You Need a New Flat Roof

There are several signs that indicate it’s time to replace your flat roof. If you notice any of the following, it’s time to call a professional for an inspection:

  • Your energy bills are increasing: If your energy bills have been steadily increasing but you can’t pinpoint the reason why, it could be due to your roof. A worn-out or damaged roof will allow heat or cool air to escape, making your HVAC system work overtime to maintain the temperature inside your home or business.
  • You have leaks: Leaks are one of the most common signs that you need a new roof. If you have water stains on your ceiling or walls, it’s likely due to a leak in your roof.
  • Your shingles are missing or damaged: Damaged or missing shingles are another sign that you need a new roof. High winds can cause shingles to blow off, leaving your roof vulnerable to leaks and further damage.
  • Your gutters are full of debris: If your gutters are full of shingle granules or other debris, it could be an indication that your shingles are breaking down and need to be replaced.
  • You see daylight through your roof: If you can see daylight shining through holes in your roof, it means your roof is no longer doing its job of protecting your home from the elements.

Conclusion:

A new roof is a big investment, but it’s one that’s necessary when the time comes.
