Heavy Rain Can Mean A Leaky Chimney

Heavy Rain Can Mean A Leaky Chimney

Spring and summer rain showers and thunderstorms are often a welcome reprieve from the scorching temperatures. In addition to cooling us off, these rain storms also keep our lawns and gardens green and our rivers and lakes full and ready for summer fun.

Unfortunately, heavy rain can also lead to a leaky chimney. Chimney leaks are one of the most common chimney problems we see during the summertime. Even chimneys without previous problems can develop leaks – and their accompanying water damage – in as little as one season.

What causes chimney leaks?

Although chimneys look like simple brick or stone columns, they are actually complex structures with a number of different pieces and parts. Because the chimney is constantly exposed to the elements, its masonry is at greater risk for damage and breakdown.

The following are some of the most common causes of chimney leaks.

Chimney cap: The chimney cap protects the top of your flue from water entry, as well as animals and debris. Without a properly fitted chimney cap, the flue and fireplace are left completely exposed to water entry from rain.

Flashing: Flashing is the water tight strips that seal the seam between your roof and the chimney structure. If flashing is incorrectly installed, damaged, or merely loses its seal due to wear and tear or age, water can easily seep through any gaps. This can cause water damage to not only the roof and chimney, but also the ceilings and walls around the chimney.

Masonry damage: If one side or part of your chimney is often directly exposed to rainfall or other sources of water, the masonry may deteriorate or become damaged faster than the rest of the chimney. Water can cause bricks to crack and spall; in addition to making your chimney look aged or unkempt, it can also affect the structural stability of the chimney and lead to chimney leaks.

Symptoms of a leaky chimney

Many homeowners falsely assume that all leaky chimneys present themselves as visible water in the fireplace or flue. However, because of the size and complexity of most chimney systems, chimney leaks are often not recognized until they’ve already caused significant damage.

Below are some of the signs that may indicate your chimney is leaking.

  • Water or condensation inside the firebox
  • Sound of dripping water in the chimney
  • Moisture, leaks, or water staining on walls or ceilings around chimney
  • Musty or dank odors, especially after it rains
  • Cracked or spalled interior or exterior masonry

Preventing chimney leaks

The best way to prevent chimney leaks is by having regular preventative maintenance done on your fireplace and chimney. Annual chimney sweepings and inspections can often identify any new chimney or masonry damage, allowing you to have it repaired before it leads to a chimney leak.

Another option for preventing leaks and water damage to your chimney is to have your masonry waterproofed. The waterproofing process involves the application of a specially designed sealant that keeps water out while allowing the masonry to retain its semi porous nature. These products can even be applied to chimneys with existing water damage as a way to keep it from getting worse.
