As a Weeping Water commercial roof repair contractor, we repair coping, parapet walls, and base flashing on older brick and stone commercial buildings.
Weeping Water commercial roof repair on older downtown buildings is mostly wall work: the coping on top, the parapet itself, and the flashing at its base.
Older commercial buildings often have tall masonry parapets around a flat roof. Water gets into the wall through cracked coping joints and loose mortar, then shows up inside along the wall line.
We repair the coping, the wall flashing, and the roof edge together, and we point out masonry that needs a mason so the roof repair stays dry against a sealed wall.
Older masonry buildings leak through the wall as often as through the roof. These are the signs we look for.
Stopping water at the top and base of the parapet protects the wall, the roof edge, and the rooms inside.
Sealing the coping and replacing the base flashing closes the two places water most often enters an old parapet. The interior plaster, wood framing, and stored goods along that wall stay dry, and the masonry stops cycling through wet and frozen every winter.
You get a list showing which work is roofing and which needs a mason.
Ladders and roofing materials go up from the alley or side lot where we can, keeping the front entrance open.
Owners rarely see their coping up close, so the report shows it joint by joint.
These repairs come up most on the older commercial buildings in Weeping Water.
Loose coping is reset and joints sealed, or metal coping caps are refastened with new joint covers.
Old flashing comes off the wall and new flashing goes up high enough to clear standing water, with a termination bar at the top.
Counterflashing set into the mortar joint is reset and sealed so water stays in front of the base flashing.
Tapered board along the wall moves water away from the parapet and toward the drain or scupper.
Wind-driven rain through a parapet shows up as damp plaster inside. Book an inspection and we will check the coping, mortar, and flashing together.
Wall repairs start with access planning, since older downtown lots leave little room for ladders.
We look at the street, alley, and side lots to plan where ladders and roofing materials go with the least disruption.
The coping, parapet faces, base flashing, and roof along each wall get checked and photographed.
Damp spots inside are matched to the wall sections above them on the roof.
Coping is reset or sealed, and base flashing is replaced up the wall.
Anything on the parapet that needs a mason goes on a separate list with photos.

Answers on parapets, coping, winter damage, cost, and our service area.
The coping, the wall flashing, and the roof edge get repaired together, since a fix at only one of them leaves water a path through the others. Cracked coping joints are reset or sealed, base flashing that pulled away is replaced, and any loose mortar that lets rain through the wall goes on a list for a mason.
Yes, coping is part of the roof edge. Metal caps get refastened and their joint covers replaced, and stone or masonry coping gets reset and sealed. Rebuilding a parapet wall itself is mason's work, and we will tell you when that is the case.
Water in the wall freezes, expands, and widens every crack it sits in. Each winter opens coping joints and mortar a little more, so a leak that was a damp spot in fall can be a steady drip by spring. Sealing the top and base before winter slows that cycle.
Wall height, access, and how many feet of coping and flashing need work. A short run of base flashing behind a one-story shop is a small job. Resetting coping along a tall parapet on a narrow downtown lot takes more setup, more material, and more hours on the roof.
We do. Weeping Water is part of our service area for older downtown buildings, shops, and offices. Call or send a message with the address and a note on where the wall or ceiling is wet, and we will set an inspection.
Tell us where the wall or ceiling is wet and how tall the parapet is. We will check the coping and flashing and send photos of each joint.
