Common Causes of Commercial Roof Leaks and Damage in Hillsboro, OR

If you’re a business owner in Hillsboro, Oregon, then you know that having a leaky roof can be a big problem. Not only is it a hassle to have to deal with water damage constantly, but it can also be very costly. Many factors can lead to a commercial roof leak, but here are some of the most common ones:

Improper Installation

This is one of the most common causes of commercial roof leaks. If your roof is not installed correctly, it’s more likely to leak. Make sure you hire a qualified contractor who has experience installing roofs for businesses.

Poor Maintenance

If your roof isn’t properly maintained, it’s more likely to leak. Make sure you have a qualified contractor inspect your roof regularly and make any necessary repairs. Frequent maintenance is also important because it will prevent leaks from becoming a bigger problem down the line. Neglecting your roof can lead to expensive damage that could have been avoided.


Bad weather is another common cause of commercial roof leaks. If there’s heavy rain or wind, water can make its way into your building through any cracks in the roof, or other weak spots on the surface. You should check for signs indicating a leak before it worsens. Or in the future, you could be looking at stains on ceilings and walls inside of your business. In addition, hail can cause severe damage to your roof and create leaks in the future if not repaired quickly.

Animal Infestation

Animal infestation is also a common cause of commercial roof leaks, especially around vents where animals might try to nest or find shelter. Make sure you clean out all debris from your vents regularly so you are sure that there aren’t any critters living up there.


All roofs eventually wear out, and when they do, they become more likely to leak. So if your roof is older, it’s essential to have it inspected regularly by a qualified contractor to ensure there are no significant problems.

Faulty Flashing

Flashing is a thin strip of metal that can be found on the edge of roofs or around chimneys and vents. It helps prevent water from getting into these areas. If your flashing becomes damaged by corrosion or rust, there will be more opportunities for leaks to occur. Also, if your flashing isn’t sealed correctly when installed, it is more likely to cause leaks in these areas.

Improper Ventilation

If your roof isn’t properly ventilated, it can cause condensation to form on the surface. This can lead to mold and mildew growth, which will eventually cause the roofing materials to deteriorate. Make sure you have a qualified contractor install vents in your roof if it doesn’t already have them.

There are many reasons why a commercial building roof may leak.

However, if the problem is large enough, it could cause damage to your business’ inventory, or even lead to a collapse of the structure itself! The best way to prevent these types of leaks is by hiring a professional contractor who has experience with commercial roof repair.
