Have you noticed an occasional leak from your roof? Sporadic leaks in your ceiling may not seem like a big deal, but don’t take them lightly. Even a single leak can quickly become worse and cause costly damage to your house and your belongings.

So why does your roof only leak sometimes? Here, we’ll show you the most common reasons your roof is leaking and what steps to take to protect your home.

Top 3 Reasons Your Roof Leaks Occasionally

1. Rainstorms

When winds are strong enough, they can blow rain sideways. This pushes water into places where it’s not supposed to go and can even wick it uphill. As a result, water gets underneath your roof’s underlayment (the layer between the shingles and the roof) if it isn’t brought up far enough.

Another reason is if a rainstorm involves heavy downpours. There may be an area on your roof where the water gathers and sits instead of draining off. These roof areas tend to slope down and flatten, preventing the accumulated rainwater from draining off the roof as quickly as it should. Roofs aren’t meant to have water sit versus run off.

2. Ice Damming

If you have snow or ice on your roof, the heat from your home can melt it. As the water runs down, it refreezes at the edge of your roof, forming an ice dam.

Ice dams prevent snowmelt and water from draining off your roof, causing it to back up under your shingles and leak into your home. Sometimes, ice damming results from an insufficient underlayment. But most of the time, it’s due to issues with your home’s ventilation system.

When the ventilation in your house is inadequate, the upper area becomes warmer than the lower area. The heat in the upper area causes ice and snow to melt and run down your roof. Then, the colder, lower areas freeze this runoff of water. If this is the case, you’ll need your ventilation system to be corrected once the snow or ice has melted and is gone.

3. Humidity & Temperature

If you have wood shakes on your roof, temperature variations and humidity can often swell the wood. This swelling leads to areas of your roof shifting, resulting in gaps that allow water to leak into the interior of your home.

What Should I Do When My Roof Leaks?

Any kind of roof leakage should be addressed immediately to prevent the enormous costs of roof replacement and interior damage.

 The first time you notice your roof leaking, take the following steps:

  1. Place containers under the leaks as close to the leak source as possible to prevent the spread of damage. Empty them to prevent further water damage to your home’s interior.
  2. Call a professional and schedule a free estimate and consultation.
  3. Prepare for the professional to visit your home. While they may inspect only the outside, they may also have to assess the interior of your home, such as your attic.
