We’ll Have Your Flashing Repaired In A Flash

Chimney leaks that originate where the roof and chimney meet can do serious damage to the home and have you up to your ears in costly repairs. How does water become such a problem in this spot? Well, the area where the chimney and roof meet is a vulnerable area because it’s not totally sealed — that’s what the flashing is for. Flashing (metal sheets layered in strategic ways) is installed over top of this vulnerable spot to seal it off and encourage rain and snow to exit the roof instead of gathering and entering the home. But flashing can still fail to keep water out for a few different reasons:

  • Improper Installation Materials & Techniques — Flashing should be made of copper or stainless steel, two incredibly durable materials. If a weaker metal is used, the flashing may rust and corrode, allowing water in. Additionally, counter and step flashing should be installed and minimal nail holes should be used to prevent water from pooling.
  • Weather Or Wind Damage — Winds can lift flashing and pull it away from the roof or chimney, and rain and snow can cause deterioration that reduces flashing’s effectiveness. Additionally, loose limbs and tree branches can hit the flashing during a storm and cause dents and other damage.
  • Animal Tampering — Just as strong winds can damage flashing, animals can lift or dent flashing as well, leaving openings and gathering spots for water.
