Chimney Flashing Repair in Palatine: What You Need to Know
Chimney flashing failure is a leading cause of roof leaks in Palatine homes. Palatine grew rapidly from the 1960s through the 1980s, and many homes from that era have original factory-built fireplaces with metal fireboxes that now need liner upgrades to meet current safety standards. The village also has a significant number of older masonry chimneys in its historic core near downtown Palatine that need tuckpointing and crown repair. Palatine's mix of housing types — from condos to large single-family homes — means we handle a wide variety of chimney and duct configurations here. The combination of aging metal flashing and Illinois winters — with ice dams forming at the chimney-roof junction — makes flashing inspection and repair a priority for homeowners in this area.

About Chimney Flashing Repair
Chimney flashing consists of two components: step flashing (L-shaped pieces of metal that interleave with the roof shingles along the sides of the chimney) and counter flashing (metal that's embedded in the chimney mortar joints and laps over the step flashing). Together, they create a watertight seal at the chimney-roof junction. Flashing is typically made of aluminum, galvanized steel, or copper. Over time, the mortar holding counter flashing in place deteriorates, the metal corrodes or separates, and the seal fails.
Failed chimney flashing is one of the top three causes of roof leaks in older homes. Water that enters through failed flashing can damage roof decking, attic insulation, ceiling drywall, and wall framing. In Illinois winters, ice dams can form at the chimney-roof junction and force water under the flashing. Addressing flashing failure promptly prevents far more expensive structural repairs.
Signs You Need It
- Water stains on the ceiling directly adjacent to the chimney
- Visible gaps between the flashing and the chimney masonry
- Rust stains running down the chimney exterior
- Flashing that's pulling away from the chimney or roof
- Caulk or tar patches on the flashing (sign of previous amateur repairs)
- Water in the firebox after rain
Our Process in Palatine
Leak source confirmation
We inspect the full chimney-roof junction to confirm flashing failure is the source of the leak and identify whether step flashing, counter flashing, or both need attention — ruling out crown and cap as contributing factors.
Old flashing removal
We carefully remove the failed flashing, clean the substrate, and prepare the chimney mortar joints for new counter flashing installation. We remove all old caulk and tar patches.
New flashing installation
We install new step and counter flashing using appropriate materials (aluminum, galvanized steel, or copper), properly interlacing with the roof shingles and embedding counter flashing in fresh mortar.
Sealing and final inspection
We apply a high-quality roofing sealant at all joints and transitions, and inspect the surrounding roof area for any related damage that should be addressed.
