Chase Cover Repair

Chase Cover Repair — Stop Rust and Water Damage

A chimney chase cover is the metal sheet that covers the top of a factory-built (prefab) chimney chase. Most homes come with galvanized steel chase covers that begin rusting within 5-10 years. Those ugly rust streaks running down your chimney siding are more than cosmetic — they indicate water is entering the chase and damaging the framing, insulation, and fireplace system inside.

Why Chase Covers Fail

Standard galvanized chase covers are the weakest link in any prefab chimney system. They sit flat (or nearly flat) on top of the chase, collecting water that accelerates rust. Once rust begins, it creates holes that allow water directly into the chase. This water rots framing lumber, saturates insulation, and can damage the fireplace pipe system — sometimes creating fire hazards.

The Stainless Steel Solution

We replace failing galvanized covers with custom-fabricated stainless steel chase covers built to last for decades. Our covers feature a raised center with proper slope to shed water, a drip edge that directs water away from the chase sides, and tight-fitting storm collars around pipe penetrations. Once installed, you'll never have to worry about chase cover problems again.

Chase Interior Assessment

When replacing a chase cover, we always inspect the chase interior for existing water damage. Rotted framing, wet insulation, and damaged fireplace pipe are common findings when covers have been leaking. We report all findings and recommend necessary repairs to ensure the entire system is safe and functional.
