Why is Good Chimney Flashing Important?

Chimney flashing is the metal sheeting on chimneys, and it must be installed correctly. Why is good chimney flashing important? Simply put, the chimney and roof over your head depend on it! When things go wrong with chimney flashing, the roof is often affected. It is not unheard of for entire roof structures to rot because of leaks in chimney flashing. A full or partial chimney rebuild may also be called for. Burlington Fireplace & Solar can be relied on for flashing repair done right. And that’s saying something because it’s not easily accomplished. We’ll explain.

What’s the Deal with Chimney Flashing?

For many chimney companies, flashing is one of the top three reasons homeowners need chimney repair. When chimney leaks become evident, the chimney flashing is frequently the culprit. Why is that? 

First, it helps to know what the flashing is supposed to do. Chimney flashing creates a watertight seal between the chimney and the roof. Although good chimney flashing installation is essential, it is very difficult to achieve. 

The top section of the flashing is embedded in mortar between bricks on the chimney stack. Even if it is done well, high winds and other extreme weather conditions can cause the flashing to pull away. The results are water intrusion in the masonry system and leakage that causes roof damage.

Why Good Chimney Flashing is Important

If not detected early enough, the damage caused by failed flashing can be very serious. Costly masonry damage and roof damage are associated with metal chimney flashing. By scheduling chimney inspections, you can rely on qualified chimney technicians to keep a close eye on the condition of your flashing. Inspections are recommended annually as well as after major weather events and chimney fires.

Even without stormy weather, the nails that attach flashing to rooftops can rust. Water leaks through, and roof damage can occur very sneakily. When flashing isn’t installed well, gaps can cause moisture intrusion in the masonry. 

Water getting into masonry may not sound so serious, but it destroys bricks. It happens in winter when the water expands and contracts every time there is a freezing and thawing cycle. The movement breaks down the bricks, and as a result, chimneys end up leaning. Full and partial chimney rebuilds often become necessary due to failed chimney flashing.
