The Dangers of Damaged or Missing Flashing

When Aelite Chimney Specialties is diagnosing water leaks, we look at the area where the chimney meets the roof. Since this area is one of the most vulnerable spots for water leaks, it should be protected by a flashing system. However, we often find chimneys that do not have any flashing installed. We also see many chimneys with damaged flashing systems, and these chimneys have suffered from water penetration damage that could have been easily prevented by a customized and well-built flashing system. This water leak preventive chimney component works well to keep water out of your chimney and home.

What is chimney flashing?

The Dangers of Damaged or Missing Flashing img - Chicago IL - Aelite ChimneyA flashing system consists of metal sheets that are wrapped around the chimney at the point where it meets the roof. Its purpose is to keep water from accumulating in this area and possibly leaking into the chimney. Flashing should be built so that water will run off away from the chimney.

How should flashing be installed?

One of the biggest sources of chimney water leaks is improperly constructed flashing. For flashing to work correctly, it is essential, according to This Old House, that there are two layers of metal sheeting used. The first layer, step flashing, consists of L-shaped sheets of metal that are embedded into the roof’s shingles and then lapped up the side of the chimney. Counterflashing is the second layer of metal sheets. It is cemented into the mortar of the chimney and folded over the top of the step flashing. Many times, the corners have not been properly finished. It is very important to adequately caulk any gaps in each corner of metal sheeting layers. If the corners have not been properly sealed with caulk, water from rain, ice, and snow can get into gaps.

How does flashing get damaged?

Strong storms can cause metal sheets to bend away and break loose from flashing systems. Wild animals like raccoons can also pry open loose flashing when trying to get into a chimney to nest. Poor construction can also lead to damaged flashing. You can trust Aelite Chimney Specialties to be sure your flashing system is built properly.

Signs of a chimney leak also include: standing water in the firebox, a musty odor, and damaged or missing bricks and mortar joints on the exterior chimney. It is important to take care of this type of problem as soon as possible. If you don’t, you could end up with extensive and expensive chimney damage!

We would like to tell you more about a couple of the most causes of chimney leaks.

FLASHING

Not having a customized flashing system to protect the most vulnerable spot for leaks, where the chimney meets the roof, is one of the most common causes for chimney leaks. Even if you have flashing installed on your roof and chimney, it may not be doing its job if it has not been properly constructed. Over our years of working on chimneys in the Chicago area, Aelite Chimney Specialties has seen how poorly built flashing can even cause chimney leaks. We take great care when measuring your chimney. Aelite can cut metal sheeting in the right sizes to protect your home from water leaks. We also make sure that all of the corners have been caulked to keep water from entering in those areas.

CHIMNEY CROWN

Since your chimney crown sits on the top of your chimney, it is directly exposed to all of the water from rain and melted ice and snow. Your crown is made from mortar that can withstand this type of exposure. However, it can still develop cracks and other types of erosion damage over time. If your crown is cracked and damaged, water can easily get into your chimney. One of the first places Aelite Chimney Specialties will look for the source of a chimney leak is the crown. If we find cracks in your chimney crown, we can repair them. If your crown is damaged beyond repair, we can construct a new one that will protect your chimney from water penetration for years.
