Chimney Repair

A chimney takes on some of the harshest exposure of any part of a roof system, facing constant freeze-thaw cycles, wind-driven rain, and temperature swings common to Chicago winters. Over time, mortar joints can loosen, flashing can separate, and small gaps can let moisture into the surrounding roof deck. Perez Roofing & Masonry Inc. addresses these issues with attention to both the masonry structure of the chimney and the roofing details that seal it against the elements.

What We Look For

Mortar joint deterioration — cracked or crumbling mortar that allows water into the chimney structure.
Flashing separation — gaps where the chimney meets the roofline, a common source of leaks.
Hidden moisture intrusion — dampness that isn't visible from the surface but affects roofing materials below.

How We Diagnose and Repair

Infrared Roof Moisture Scanning — identifies hidden moisture around the chimney base before it spreads.
Moisture Meters — pinpoint specific areas of water intrusion for targeted repair work.
Sheet Metal Flashing Fabrication — custom flashing rebuilds a tight seal between chimney and roof.
Tuckpointing Grinders — precise mortar-joint work restores the chimney's masonry integrity.

Owner Francisco Perez oversees this work personally, drawing on the company's combined roofing and masonry background to treat chimney repair as both a structural and weatherproofing task, not a surface fix.
