Proper Protection

Protect Your Home with Copper Chimney Flashing

While a fireplace is a great way to stay warm during the winter, it can pose a threat year round if not protected. Chimneys without copper flashing run the risk of water leaking into the roof decking, attic and home, causing headaches for the homeowner that could have been avoided. The Clearview team has been properly protecting Long Island chimneys and homes for the past 60 years and can help you proactively protect your home today.

Add Protection & Appeal

Copper chimney flashing is a great way to not only protect your home by protecting against water seeping in, but also a great way to add appeal to the exterior of the home. It’s an added layer of protection that, while might be small, provides a large impact.

CLEARVIEW Roofing repaired the white aluminum fascia molding that blew off with the recent storm we had. I called and spoke to Chris. After talking to him on the telephone I texted him photos of the aluminum that needed to be replaced. In no time he responded with an estimate that was fair and reasonable. A crew arrived the next day to do the work. Great Job!! Well done! I highly recommend Clearview Roofing!!

Fixing a chimney leak can be a complex task and may require our professional assistance. However, here are some steps you would take to fix a chimney leak:

  1. Identify the source of the leak: Check the roof and the chimney itself to identify the source of the leak. Look for cracked or missing shingles, damaged flashing, or missing mortar between the bricks.

  3. Repair or replace flashing: If the flashing around the chimney is damaged or missing, you may need to replace it. Use a pry bar to remove the old flashing and then replace it with new flashing.

  4. Repair the chimney crown: The chimney crown is the top part of the chimney that helps keep water out. If it’s cracked or damaged, you may need to repair or replace it. Use a masonry caulk to fill in any cracks.

Chimney flashing is a construction technique used to prevent water from penetrating the joint between a chimney and the roof. The flashing consists of thin strips of metal, typically aluminum, copper, or galvanized steel, that are installed at the base of the chimney and run up the sides and over the top.

How does Chimney Flashing work?

  1. The base flashing is installed at the bottom of the chimney, where it meets the roof. The flashing is typically L-shaped, with one leg extending up the side of the chimney and the other leg lying flat on the roof.

  2. Step flashing is installed on the sides of the chimney. These small pieces of flashing are installed one at a time, with each piece overlapping the previous one and extending up the side of the chimney.

  3. Counter flashing is installed over the step flashing and is bent down to cover the top of each step flashing piece. This creates a waterproof seal that prevents water from seeping in around the chimney.

  4. Finally, a cap flashing is installed over the top of the chimney. This is a flat piece of metal that extends out from the chimney and over the roof. It is bent downward at the edges to create a drip edge that directs water away from the chimney and onto the roof.

Overall, chimney flashing works by creating a watertight barrier around the base of the chimney, preventing water from seeping in and causing damage to the roof and the interior of the home.

The cost of chimney flashing in Long Island, NY can vary depending on several factors such as the size of the chimney, the type of roofing material, and the extent of the damage or deterioration that needs to be repaired.
