Leaky Chimney Flashing? We’re Here to Help

If your chimney is leaking, determining how the water is coming in can be a difficult process. Because the chimney is constantly exposed to the elements, there are a number of ways that water can get in. If you have water staining the ceiling or walls surrounding your chimney, don’t blame your roof – faulty flashing may be to blame.

Chimney Flashing

What Is Flashing?

Flashing is the series of metal strips that seal the joint between your chimney and your roof line. Through layering and strategic overlapping, flashing is designed to create a waterproof seal that protects your chimney, roof and interior from water entry or damage.

When correctly installed and maintained, flashing can keep this watertight seal for the life of your chimney system. However, there are a number of things that can cause flashing to fail. Here are some of the reasons for flashing leaks:

  • Incorrect installation, including too many nail holes
  • Changes to the roof, such as having shingles replaced
  • Natural shifting or settling of the house
  • Long-term exposure to the elements
  • Attempted animal entry

How Can I Tell When My Flashing Needs Repairs?

Knowing when your flashing needs to be repaired can be tricky, as it can be hard to see without climbing up onto the roof. Because of this, many homeowners are unaware that their flashing is damaged until they have a leak – and a lot of extra damage – on their hands.

Here’s what we advising looking for:

  • Pools of water in your firebox
  • Rusted metal components
  • Mold or mildew growth
  • Water stains on the walls or ceiling near your fireplace

All that said, rather than waiting until you have a leak to have your flashing evaluated, consider booking an annual chimney and fireplace inspection to avoid the leak altogether.

An annual inspection will include an evaluation of all accessible parts of your fireplace and chimney – including the flashing – which allows you to better understand the overall condition of your fireplace system.

Likewise, any time you have repairs made to your roof, consider having chimney professionals evaluate your flashing. One of the most common causes of flashing leaks is through changes to the roof. Whether you are having shingles near the chimney replaced or are shingling or tiling the entire roof, call Wells & Sons Chimney Service to evaluate your chimney flashing and make sure it has retained its watertight seal.
