What Is Placed Around Chimney’s To Prevent Leaks?

Water damage is a serious concern for many aspects of a home. And your chimney is no different. Luckily there are many pieces of a chimney to protect it from unwanted water finding its way inside. Chimney caps and chimney crowns play a role in not only keeping water out, but also debris and even animals. However, the main player in keeping water out is roof flashing.

What is flashing?

When your house was built or the chimney was installed, the contractor likely used a type of flashing to protect from leakage. Flashing is made of a metal material installed wherever there would otherwise be a gap. The roof flashing creates a watertight seal while also directing water down and away from the chimney. This type of material is also found around dormers as they protrude from the roof and require a watertight seal.

I have flashing, why is my roof leaking?

It’s possible that you can experience issues even if there is roof flashing installed. First, it’s possible that when the flashing was installed, it wasn’t installed with a complete watertight seal. This is unfortunate, but if you realize this very close to installation, that is likely the cause. Make sure to call your contractors to see if they can help fix the situation.

Another reason the flashing may be failing is due to time and wear. Just like any aspect of a home, it doesn’t stay in tip-top shape forever. It may be time to call the professionals to replace roof flashing on your chimney.

Lastly, it’s important to note that if your roof is leaking, it may not be due to flashing. Depending on the quality and age of your roof, you may need an entire roof replacement. Luckily, an inspection of the chimney typically includes our professionals going onto your roof to determine the status of your flashing to rule that out or not. 

Types of Flashing

Under the umbrella of roof flashing, there are a few different kinds that can work to keep water out.

Step Flashing

This is a popular type of flashing used against the sides of chimneys. It’s installed against the side of the chimney and installed panel by panel to ensure the watertight seal is intact.
