5 Common Causes of Roof Leaks

There are few things worse than a leaking roof in the middle of a storm, and it becomes even more frustrating when you don’t know where the leak is coming from or what caused it.

Common Causes of Roof Leaks

We’ve compiled a list of the most common causes of roof leaks, so the next time you hear the telltale dripping, you’ll know where to look first and what caused it.

  • Cracked flashing - Flashing is a thin piece of metal that is installed under the shingles and on the joints of your roof as a water-resistant barrier. Over time, the flashing will eventually wear out and form large cracks. These cracks make it easier for water to seep under your roofing tiles and into your home. This issue can be aggravated further by strong winds, hail, and branches falling on your roof.
  • Broken shingles - Unfortunately, broken shingles are not just an aesthetic issue for your home. Cracked shingles are often caused by strong winds, heavy rain, hail and falling debris, which is one reason it is of the utmost importance that you keep your trees well trimmed. Because roof shingles are the outermost layer of your home and the first line of defense when it comes to severe weather or falling objects, it is so essential to make sure your roof shingles are in the best condition.
  • Loose skylights - If a skylight is not installed correctly in your home, then you could be left with potential vulnerabilities including leaks. Additionally, if your skylights are older, then you could have a problem with the insulation. Over time it deteriorates and leaves gaps between the skylight or window and the casing. Since skylights are installed on the ceiling and roof of your home, they are particularly vulnerable to leaks, especially during heavy storms. The same goes for windows that have been improperly installed. If there is space left between the window and its casing, then water can easily seep in. If you suspect that your home is suffering from leaks like these, then call a professional home exteriors expert right away!
  • Clogged gutters - Clogged gutters are another common cause of water leaks and water damage. The purpose of your gutters is to provide a path for water to travel from your roof and away from your home, but your gutters tend to catch debris like leaves in them which lead to blockages. When your gutters become clogged, water no longer has a clear path to flow which leads it to spill over the edge of the gutter and down the side of your house which can lead to water damage and future mold growth.
  • Moisture in the attic - Your attic is the uppermost part of your home and is therefore trapped directly between the indoor and outdoor temperatures. So in the middle of a hot summer, when the temperatures are reaching 90 degrees and the temperature inside your home is closer to 75 degrees, condensation forms and in the worst circumstances, mold is close behind. At the first sign of a leak or water damage in your home, you should contact a professional roofer to examine the issue. One of the worst things you can do is wait for the problem to grow even larger or into something else altogether.
