Missing or Broken Shingles

This is one of the most obvious causes of roof leaks. Shingles are designed to protect the underlying roof structure. However, they can only do so if they are properly in place. If they are absent or cracked, the roof may leak. Replacing the affected shingles is a simple enough solution. The only question is whether you need to replace a few or a lot. If it’s time for a new roof, clay or tiles are a more durable option.

Rain and Wind

Rain on its own won’t cause your roof to leak unless the roof wasn’t properly installed. However, rain and wind together can cause your shingles to lift and shift. This allows debris to get under the roofing material, creating a weak spot where water can seep in. Sometimes the solution is as simple as finding the shingle that lifted and removing the debris. The shingle may also just need to be shifted back into position. However, in more advanced cases, a whole section may have to be repaired.

Trees & Leaves

Trees look beautiful and they can keep your home cool. However, leaves can get everywhere, especially during the fall. They will gather in your gutters and valleys and prevent water from flowing off the roof. Over time, the moisture can wear down the roofing material. Falling branches or those that repeatedly scratch against the shingles can also cause damage. Trimming any trees that are directly over your home is the best way to prevent these problems. If you already have a leak, you’ll need to remove the debris and determine the full extent of the problem. if you have to replace the roof, a living roof may be a great option if you like to have trees around.


The south and west-facing areas of your roof will get the greatest impact of the sun’s ultraviolet rays. The sun will cause your roof to deteriorate and make it more susceptible to leaks. If you have a leak in an area of the house that’s not under a tree or valley or missing shingle, it could be due to the sun. It’s best to get a roofing professional to inspect the damage. While one small leak can be patched, multiple leaks may indicate it’s time to replace your entire roof. Metal roofs are highly resistant to the sun.

Flashing Cracks

Flashing is used to direct water away from pipes, chimneys, skylights and other openings on the roof. However, if it was installed incorrectly or it gets damaged, water can pass through. If your flashing is cracked, you need to contact a roofing specialist to find out why. Getting annual inspections will ensure problems are detected early.

Improperly Sealed Valleys

Debris can easily collect in the valleys of your roof and cause water to pool. Standing water will always cause roofing problems and it is a common cause of roof leak. If your valleys aren’t properly sealed, you could be in for trouble. The repairs will need to be done by a roofing professional and you should schedule them before the problem gets too bad. To prevent problems with your valleys, make sure that you or anyone else who goes on the roof never steps on them. Valleys can be easily cracked.
