Permanent Flashing Repairs vs. Temporary Caulking

Amateur handymen often attempt to fix chimney leaks by slathering silicone or asphalt tar over the existing metal joints. In North Texas summer temperatures—where roof surfaces routinely reach 150°F—topical sealants dry, shrink, and crack within months, trapping moisture beneath the caulk and rotting underlying roof sheathing.

Vetted independent roofing contractors resolve flashing failures by:

  • Removing Degraded Shingles & Metal: Opening up the junction to inspect the roof deck for hidden dry-rot or fungal growth.
  • Installing Ice & Water Shield: Adhering rubberized self-sealing membrane directly to decking and vertical chimney/wall interfaces.
  • Fitting Custom-Bent Gauge Metal: Installing new 26-gauge galvanized, aluminum, or copper step flashing and counter-flashing tucked into mechanical reglet joints.
  • Building or Rebuilding Chimney Crickets: On chimneys wider than 30 inches, installing a peaked saddle (cricket) that diverts water around the brick structure rather than allowing it to dam against the uphill face.
