We Install Custom Flashing


When you look up at your home from the street, you’ll see a pop of metal flashing around the chimney where it rises up from the roof. With sleek stainless steel or eye-grabbing copper, that flashing can add a note of visual appeal, but it’s certainly not just adornment. Your flashing plays a key role in protecting your chimney system and your home’s interior from the intrusion of water.

Your chimney system has a smart design: Anywhere in its construction where there are potential vulnerabilities to water, there are preventative measures built in to protect it. That includes a masonry crown or chase cover, a chimney cap at the top of the flue, a damper, and flashing around the joints of the chimney where it exits the roof.

Without flashing, water would pool at the seams where the chimney and roof meet, and trickle right into your home, damaging ceilings, walls, and masonry. Flashing helps keep that from happening, and when designed and installed correctly, it can provide protection for years. Unfortunately, particularly with severe weather, it’s not unusual to see flashing strips damaged or ripped off, or for the caulking that’s installed around the edges to loosen or come off. When that happens, it’s important to have the flashing repaired as soon as possible, so that further damage isn’t done to your home.

Constructing And Installing Flashing Is Custom Work

Flashing is constructed and installed in several layers, to provide thorough protection for your chimney. First, L-shaped step flashing is installed around the bottom and integrated in with your roof shingles. On top of the step flashing, counter flashing is installed into the mortar joints on your chimney, and then the edges are protected with high-quality caulk. When the process is complete, your chimney has strong and smartly designed protection that should ably keep water at bay for a long time.

Every chimney system is slightly different, and in order for flashing to work correctly, it needs to be custom-made to fit your chimney exactly. It takes skills and experience to do flashing repair and installation properly, and Blue Sky Chimney Sweeps’ technicians are up to the task.
