Common Causes of Roof Leaks


Your roof is the first line of defense against debris, wind, rain, snow, etc. And it’s also one of the most expensive pieces in your house. Keeping it safe from harm is not only good for your bank account, but it also benefits the rest of your home’s structure as well as everything inside of it.

There are many reasons your home could develop a roof leak, but some are more common than others. Keep reading to learn more about the most common causes of roof leaks.

Age of the Roof

As roofs age, they can begin to leak for a variety of reasons. One of the most common reasons is that the materials used in the roofing system break down over time. This can cause gaps and seams to form that allow water to seep into the building. In addition, moss and other growths can accumulate on the roof, softening the shingles and leading to leaks.

The average lifespan of a roof is around 25 years; however, to get the most accurate estimate, we would need to know the type of roof that you have. The more seams that are in your roof (think about asphalt or shingle roofing), the more likely it is that a leak will develop over time. As your roof gets into its more senior years, make sure that you’re more diligent about scheduling inspections and staying on top of maintenance to avoid major damage.

Installation and Maintenance of the Roof

Another common cause of roof leaks is improper installation or maintenance of the roofing system. Although commercial and residential roofs are designed to last for many years, they can develop leaks if they are not properly installed or maintained. Improper installation can cause gaps and seams in the roofing system, allowing water to seep into the building. In addition, improper maintenance can allow moss and other growths to accumulate on the roof, leading to leaks.

Weather Conditions

Leaking roofs can also be caused by severe weather conditions, such as high winds, hailstorms, or hurricanes. These conditions can damage the roofing system, causing gaps and seams that allow water to enter the building. In addition, severe weather can also damage the gutters and downspouts, which can cause water to back up onto the roof.

If you think your roof may be leaking, it is important to have it inspected by a qualified roofing contractor. The contractor will be able to determine the cause of the leak and recommend the best course of action to repair it. The leak can sometimes be repaired without replacing the entire roof. However, if the damage is extensive, it may be necessary to replace the roof. If you are having problems with your roof or think it may be leaking, contact a qualified roofing contractor today. They will be able to inspect your roof and determine the cause of the leak. They can also recommend the best course of action to take to repair the leak.
