Over the years, the metal covers on most pre-fab chimneys start to rust due to moisture (rain, ice and snow) that sits on the metal for extended periods. Along the way, pine straw and leaves land on top as well. When this material starts to decay, it creates a very acidic condition that eats the galvanized coating off the metal.
It can take as little as 5 years of this condition before you see rust running down the side of your chimney. Eventually, the metal starts to pit (rust through) allowing water to drip inside the chimney structure. You may hear the dripping sounds sometimes when it’s quiet in the home, after a rain. When you see the rust stains, it is time to replace the top SOON. That’s where we come in…
CHASE COVERS
Chase covers are generally found on pre-fabricated or factory built chimneys. They are usually metal and keep debris from falling into the open area.
