The last time it rained, did you notice water dripping from the ceiling? If so, this could mean that you have a leaky roof. If the leak is near your chimney, however, you may have a damaged flashing system instead of a roof problem. This type of damage is more common than you may think. However, the good news is that fixing this problem is much less expensive than getting a new roof. Are you not sure what could be causing your water leak? Ashbusters is here to help you diagnose the issue! We can inspect your flashing system. In addition, we can repair damaged flashing. Also, build a new customized system to protect your chimney and roof. We would like to tell you more about chimney flashing and why it is so important. 

What exactly is a flashing system? 

Consisting of custom cut sheets of metal, chimney flashing protects one of the most vulnerable areas for water leaks. This is where the chimney meets the roof. According to This Old House, a good flashing system should include two layers. The first layer, step flashing, is made up of L-shaped sheet metal that are woven into the roof shingles and lapped up the side of the chimney. The second layer, counterflashing, is embedded in the mortar joints of the chimney. This top layer is folded over the top of the step flashing. Our chimney technicians at Ashbusters take great care to be sure each corner is covered completely and securely. We use high-quality caulk to fill in any gaps or cracks. This ensures the flashing makes a watertight seal where your chimney meets the roof. 

How does flashing become damaged? 

Strong storms can do a number on even the best built flashing systems, but the most common culprit is time as the sheets of metal can break and crack from corrosion damage. Wild animals like raccoons and squirrels can also damage flashing when they attempt to get into chimneys to nest. Also, flashing systems take precise and careful measurements to properly construct. Ashbusters has seen many poorly built flashing systems that actually have caused water leaks. You can trust us to take the time to do a proper flashing job that will keep water out of your chimney and home!
