How to Effectively Repair a Leaking Chimney: Expert Tips



A leaking chimney is a common issue that can cause significant damage to your home if not addressed promptly. At Equity Roofing, we've seen our fair share of chimney leaks and have honed our expertise in fixing them. This article aims to provide you with actionable steps to repair a leaking chimney, whether you're a homeowner looking to DIY or seeking professional Central PA roofing services.

The Importance of Counter Flashing

Counter flashing is a critical component in preventing chimney leaks. Often, the issue stems from improper installation of this element. The correct method involves grinding a quarter-inch into the chimney and inserting a custom-bent piece of counter flashing. Many roofers in Central Pennsylvania take shortcuts, leading to leaks down the line.

Steps to Fix Counter Flashing

  • Material Preparation: Use aluminum stock coil to bend your new counter flashing. Match the color with the fascia for aesthetic consistency.
  • Tools Required: Carry silicone, pencil, caulk gun, hand brake, battery-powered air blower, hammer, and tin snips to the roof.
  • Grinding and Installation: Mark the chimney with a pencil where the counter flashing will go. Grind about ¾ of an inch into the chimney and ensure an even grind. Insert the pre-bent metal into the grind and secure it with silicone.

The Necessity of a Chimney Cricket

Chimneys located in the middle of the roof often require a cricket—a small, ridge-like structure that directs water away from the chimney. Without a cricket, water and snow accumulate, leading to leaks and structural damage.

Steps to Install a Chimney Cricket

  • Measure and Cut: Measure the distance from the chimney to the roof and cut a 2x4 to create the ridge piece.
  • Installation: Center the 2x4 ridge piece against the chimney.
  • Plywood Cutting: Measure and cut a sheet of plywood to fit the cricket structure.
  • Assembly: Use nails or screws to assemble the cricket. Ensure it's securely attached to both the chimney and the roof.

Emergency Fixes for Persistent Leaks

If your chimney is still leaking despite your best efforts, temporary fixes can help. Use silicone to seal the corners and tops of the existing counter flashing. While these are not long-term solutions, they can provide temporary relief until you can consult with roofing companies in Central PA like Equity Roofing for a more permanent fix.
