What Causes a Roof Leak and How to Fix It

04 May 2021

Is Your Roof Leaking?

Your roof system is the first line of defense from all sorts of weather. Rain, hail, sleet, snow, and more – it is important your roof is in the best condition to protect your home from any sort of leaks. Small damage to your roof may seem not a big deal at the moment, but it can lead to costly repairs down the road. If you are experiencing roof leaks, it is crucial to get them checked out right away.

What Causes Roof Leaks?

Everything on the exterior of your home from the roof down is important in protecting it in some sort of way. The smallest defect on any part of your home can allow water infiltration resulting in your roof leaking  . When heavy rain happens, the chances of developing a leak increase. We have broken down each part of your roof and how it can be affected by any sort of heavy rain that can turn into a serious roof leak.


Skylight windows provide a nice aesthetic to your home. Who doesn’t want more natural light inside their home? With heavy rains and high winds, this can make them more likely to leak.

Plumbing Vent Stacks & Fan Vent Hoods:

Plumbing can be another issue for a roof. A broken or incorrectly installed plumbing vent stack will leak in heavy rain. In addition, fan vent hood flashings and furnace flue flashings are sources for leaks.

Chimneys and Chimney Chase:

Brick and mortar chimneys can allow water infiltration due to cracks in the cap and mortar joints. If you have a brick and mortar chimney, take a look at it for cracked joints or missing bricks or pieces of brick missing. The flashing can also be the culprit as well.

Damage To Your Roof:

If you need to fix a roof leak only after having it recently installed, you might have had a botched job done and likely by new contractors or unreliable storm chasers. While often the cause of a leak is defective or failing flashing, caulk, or something else, it is possible that you may have sustained actual damage to your roof due to harsh weather elements.
