6 Common Causes of Roof Leaks

6 Common Causes of Roof Leaks

A roof leak can be a huge headache for any homeowner. Not only does it cause damage to your home, but the water entering your house through the roof can lead to mold and mildew growth in hidden areas inside the walls or ceiling. It’s important to identify and fix roof leaks as soon as possible before they cause extensive damage. But first, you need to know what is causing them in order to fix them properly. In this article, we will go over seven common causes of roof leaks and how to repair each one. So let’s get started! 

Improper Installation

One of the most common causes of roof leaks is improperly installed shingles. It’s important to make sure that your shingles are securely attached and have enough overlap to prevent water from seeping in. You can easily check for loose or missing shingles by walking around your house and inspecting the roof. If you see any missing shingles, replace them as soon as possible.

Damaged Flashing

Another common cause of roof leaks is damaged flashing. Flashing is the thin piece of metal that goes around chimneys, vents, and other protrusions on your roof to provide a waterproof barrier. Over time, this flashing can become corroded or cracked due to exposure to weather elements such as rain and snow. If you notice any signs of damage, replace the flashing as soon as possible to prevent roof leaks. 

Damaged Gutters or Downspouts

A third cause of roof leaks is old or damaged gutters and downspouts. If your gutters are clogged with debris or if they have been damaged over time, water will not be able to properly drain away from your house. This can lead to water seeping through your roofing material and eventually into your home. Make sure that you regularly clean out your gutters and inspect them for any damage. 

Weather Damage

Another common cause of roof leaks is damaged shingle tabs. Shingle tabs are the strips of material that cover your roofing nails or staples, protecting them from the elements. Over time, exposure to the sun and wind can cause these shingle tabs to become degraded, leaving your roof vulnerable to water damage. If you notice any missing or broken shingle tabs, replace them as soon as possible in order to prevent further damage. 

Poor Ventilation

A sixth cause of roof leaks is poor ventilation along the ridge line and valleys on your roof. Poor ventilation can lead to trapped heat and humidity which can cause moisture problems over time. Make sure that your attic is properly ventilated and inspect the ridge line and valleys of your roof for any signs of damage or wear. 

Ice Dams

Finally, the seventh cause of roof leaks is ice dams. Ice dams form when melting snow refreezes at the edge of your roof, preventing water from draining off properly. This can lead to large pools of standing water on your roof which will eventually seep into your home through any gaps or openings in the shingles and other materials. To prevent ice dams from occurring, make sure you have proper insulation in your attic as well as a working gutter system that can drain away excess moisture.
