Parapet Wall Repair
Exposed on three sides with no roof above it, the parapet fails first.
Overview
A parapet is the section of wall that rises above the roofline. Exposed to weather on the front, the back, and the top — with no roof overhang to protect it — it takes more abuse than any other masonry on the building and is usually the first to fail. Failed parapets leak into the top floor, drop mortar and brick to the sidewalk, and lean over time into a genuine safety hazard.
We repair and rebuild parapets: full-depth repointing on both faces, brick replacement, resetting or replacing coping on proper flashing, and partial or full rebuilds where the wall has gone out of plumb. The details that make it last — through-wall flashing, coping with overhang and drip edge — are exactly the ones most failing parapets never had.
Scope of Work
- Parapet repointing (both faces)
- Coping reset and replacement
- Through-wall flashing installation
- Partial and full parapet rebuilds
- Spalled brick replacement
- Roof-to-wall counterflashing coordination

Warning Signs
When to Call Us
01
Cracked or Displaced Coping
The cap on top of the parapet is the first line of defense. Cracked, loose, or missing coping lets water straight into the top of the wall — the most common starting point for parapet failure.
02
Open Joints on the Roof Side
The back face of a parapet is the most neglected masonry on any building because nobody sees it. Open joints there feed water into the wall from a direction owners rarely check.
03
A Wall That's Out of Plumb
Sight down the length of the parapet. Bows, leans, or bulges mean saturated, freeze-damaged masonry is losing its grip — a structural and safety issue, not a cosmetic one.
04
Top-Floor Ceiling Stains
Water stains along the top-floor ceiling line after wind-driven rain often trace straight back to a failing parapet or its coping rather than the roof itself.
Materials We Use
- Stone, precast, or metal coping with overhang and drip edge
- Continuous through-wall flashing membrane
- Weather-matched mortar for both faces
- Matching replacement brick

Making the Right Call
Parapet repair vs. full rebuild
A plumb parapet with sound brick can be repointed and re-capped in place. A leaning or bowed parapet, or one with brick too far gone to hold mortar, needs to come down to a sound course and be rebuilt with new flashing and coping. Patching a moving wall only hides the problem.

FAQ
Common Questions
Because tuckpointing alone doesn't fix the coping or flashing. If the cap on top of the wall is cracked or has no water barrier beneath it, water pours straight down into the masonry no matter how good the joints are. A lasting repair addresses the top of the wall and the flashing, not just the face.
If the wall is still plumb and the brick is sound, we can repoint, replace bad units, and re-cap it in place. If it's leaning, bowing, or the brick crumbles when worked, a partial or full rebuild is the honest fix. We assess plumb and brick condition before recommending.
Yes. A parapet that leans or bows over a sidewalk or entrance is a falling-masonry risk and a liability concern. If yours is visibly out of plumb, treat it as urgent and keep people clear of the area below until it's assessed.
The hidden details: continuous through-wall flashing at the base of the parapet, coping with proper overhang and a drip edge bedded on flashing, full-depth repointing with matched mortar, and the wall tied back to the structure.
