While commercial roofs are designed to last decades, there are some signs of wear and tear you can be on the lookout for.

By spotting these signs early you can avoid spending thousands of dollars in major repairs and prolong the life of your roof.

  1. Leaks

Leaks are one of the most obvious signs that your roof needs repaired. If you have a leak it is important to have it repaired right away. Leaks don’t get better they only get worse. It’s also important to find the cause of the leak and repair it as leaks are usually the result of a larger problem. Things like an increase in humidity in your building can be a sign that there is a leak somewhere. You can prevent leaks by checking your roof for standing water. If water is still on the roof a few days after a storm this can be a sign that there is not enough drainage, and this can lead to leaks and roof failure.

  1. Mold or Foul Odors

Another sign that you may need to repair your roof is mold or foul odors in the building. Mold can lead to serious health issues and needs to be taken care of immediately as it can also very quickly spread throughout an entire building. Small problems like this can indicate much larger unseen problems so it’s important to have a professional inspect everything thoroughly.

  1. Tears, Cracks or Blisters on the Membrane

Another obvious sign your roof needs repaired is tears and cracks in the membrane. However, blisters and blemishes can also be a sign repairs need to be done. Blisters occur when moisture or air become trapped between the deck and the membrane. If these are ignored, they can lead to other more severe problems.

  1. Water Stains on the Inside of Walls

Water dripping through the ceiling onto the floor is not the only way roofs can leak. Water might also leak into internal ceilings and walls causing water stains. If you notice water stains on the ceiling or walls this is a good sign you need to have the roof inspected for damage.

  1. Damaged Flashing

Flashing is the metal strips that run along the edge of the roof to connect adjacent walls or other joints in the roof. Flashing is essential in keeping out water from leaking through the roof. If flashing is rusted, bent or cracked this will allow water to run inside the roof seams. If you notice any defects in the flashing these need to be repaired right away as this can quickly lead to your roof leaking.

  1. Increase in Utility Bills

If you notice an increase in your utility bills this can be a sign your roof has an issue that needs repairing. Your roof protects the insulation and ventilation systems that keep your building comfortable for humans to be in. If the roof is comprised in some way such as a leak, this can cause the insulation to become less effective and will result in an increase in utility bills.
