Parapet Wall Repair

Parapet walls take the brunt of Chicago's weather, sitting above the roofline where wind, ice, and rain hit hardest. Over time, mortar joints loosen, coping stones shift, and water finds its way into the wall itself, often traveling down into the roof system before it ever shows up as an interior leak. Parapet wall repair addresses these entry points directly, restoring the wall's structure and its seal against the roof below.

Common Signs a Parapet Wall Needs Attention

Crumbling or missing mortar — gaps between bricks or stones let water track into the wall and down toward the deck.
Cracked or lifted coping — the cap stones on top of the wall shift and open pathways for water.
Staining near the roofline — discoloration on interior walls often traces back to a failing parapet.
Separated flashing — where the wall meets the roof membrane, worn flashing lets water bypass the seal entirely.

How We Approach the Repair

Drone Roof Inspections let us examine the wall and its flashing from every angle without extra foot traffic on the roof. Infrared Roof Moisture Scanning helps locate moisture that has already worked its way beneath the membrane near the wall base. From there, Tuckpointing & Mortar Systems restore the masonry itself, while Flashing & Scupper Systems re-establish a tight, water-shedding connection between the wall and the roof.
