Roof leaks can lead to mold growth and structural issues within a couple of days if left unchecked. Additionally, they are responsible for many of the life-threatening incidents occurring inside homes such as fires, short circuits, and even electrocution. So, it would not be an exaggeration to say that roof leaks must be addressed immediately. Otherwise, they have far more severe implications than just causing water intrusion.
That’s why; you should always keep an eye out for the common causes and signs of roof leaks in your home. With that in mind, let’s look at some of the most common causes of a roof leak that must be addressed immediately with proper repair and maintenance.
1. Cracked or Damaged Flashing
Flashing is a thin piece of metal or other material that creates a water-proof barrier around the most vulnerable parts of your roof. It is usually installed around the joints and under your roofing shingles. Damaged flashings can be identified with their large cracks that professionals usually fill with tar. However, with regular wear and tear and exposure to harsh elements, the flashing can develop gaps and cracks that can eventually lead to roof leaks.
2. Broken Shingles
Shingles form the outer layer of a roofing structure. They serve as a protective cover for the inner components of your roof, as the underlayment, to provide a water-resistant barrier to the roof. You can easily determine if your roof has missing or damaged shingles by conducting a simple visual inspection yourself. Detecting and fixing broken shingles promptly can also help prevent further damage. Missing or damaged shingles can make your roof more vulnerable to the elements that can lead to water intrusion in your home if repaired or replaced immediately.
3. Improper Ventilation
Roof leaks can also be caused by poor ventilation. Improper venting usually leads to two issues in a home: excess condensation in the attic and leaking vents. Moisture buildup in the attic can make it a breeding ground for mold growth. Not only will this compromise the structural integrity of your roof, but it can also lead to roof leaks over time. Additionally, excess condensation can also cause severe damage to the underlying parts of your roofing system such as rotting wood deck. Likewise, improperly installed, or sealed vents can lead to roof leaks in heavy rains.
4. A Low Slope Roof
Wind can easily lift shingles in roofs having shallow slopes. This can lead to roof leaks during extreme weather conditions. In general, the slope is calculated as the ratio of vertical height and horizontal length of 12 inches. If you’re building an asphalt shingle roof, the slope of your roof must be over 2:12.
5. Ice Dam Formation
Ice dams usually form at the edges of a roof during heavy snow. Once formed, ice dams obstruct the flow of melting snow and water and prevent it from draining off the roof’s surface efficiently. Consequently, the water starts accumulating on the roof. And, this standing water, along with snow, can put an excessive burden on the roof, causing structural damage over time.
Ice dams are usually formed when heat escaping from the home causes snow on the rooftop to melt. Since the outside temperature is below the freezing point, the melting snow re-freezes when it reaches the edge of the roof. This leads to the formation of ice dams on the edges.
