Parapet wall restoration in Westchester is mostly work on flat-roofed city buildings, the apartment houses and older downtown blocks of Yonkers, Mount Vernon, New Rochelle, White Plains, Port Chester and Peekskill. We reset copings over new through-wall flashing, finish the roof side with counterflashing, and brace or rebuild leaning parapets with an engineer, across Westchester County and in Yonkers.
Parapet wall restoration brings the top of a wall back into working order, so it sheds water and stands safely above the street. A parapet is the part of a wall that rises above the roof line, and in Westchester most of them stand on flat-roofed apartment houses and commercial blocks rather than on houses, whose pitched roofs usually end at a gutter.
We restore parapets across Westchester County and in Yonkers. Copings and caps are reset or replaced in stone, metal, brick and other materials, through-wall flashing goes beneath every coping we reset, and the roof side is finished with counterflashing, so the wall is closed from above and from behind.
Most Westchester owners call about a parapet after a stain on a top-floor ceiling, a piece of coping found on the roof, or a wall that looks out of line from the street. The cause is almost always at the top of the wall, and restoration works through these six parts in turn.
The damage behind each one is described in our guide to common parapet damages.
Loose, cracked or missing copings and caps are lifted and reset, or replaced in the same material or in one with fewer joints.
A new run of flashing goes down before each coping is re-laid, so water that gets past a joint is turned back out of the wall.
Counterflashing set into the masonry covers the top edge of the roofing where it turns up the back of the parapet.
Mortar at the top of a parapet takes the most weather, so joints that have opened up there are repointed before water reaches the middle of the wall.
Where an engineer finds the wall sound enough to hold, it is tied back to the building behind it and left standing.
Where the lean has gone too far, or rusting metal has split the brick, the parapet is taken down and relaid as the engineer directs.
Under 1 RCNY §103-15, every parapet facing a public street must be observed once a year, but only inside New York City. A street-facing parapet on the Bronx side of the city line has to be looked at every year, while the same kind of building a few blocks north in Yonkers does not.

Without a deadline, a Westchester parapet usually gets repaired only once a top-floor ceiling stains or a piece of coping turns up on the roof. Owners who want the wall looked over before that point can book a parapet wall inspection in Westchester, and the repairs it calls for are the work on this page.
The coping is the covering along the top of a parapet, and the Brick Industry Association’s Technical Note 36A treats each coping material on its own terms. Westchester’s flat-roofed buildings carry all four, often more than one on the same roof.
Laid in small units, so it has many joints, each bedded in mortar on the wall. Every joint is a way in, and one open joint lets water straight down into a Westchester parapet.
Long pieces with few joints, which can usually be fixed rigidly to the wall below. The anchor holes are the weak point, and each one has to be sealed.
Lapped lengths nailed through horizontal slots, so the metal can slide as it warms and cools. Fixed tight, it pulls its own fastenings loose.
Carried at least four inches down the wall and finished with sealant. A cap that stops short is the one the wind lifts off a Westchester roof.
Where a brick coping keeps opening up, the answer is sometimes fewer joints rather than more mortar, and that is a choice made with the owner before work starts.
The coping comes first, then the seams between its pieces, the roof face and whether the wall still stands plumb. If the Westchester parapet has moved, an engineer looks at it with us.
Each coping or cap comes up, a new run of through-wall flashing goes down, and the coping is relaid in whichever material suits the building, in Yonkers or anywhere else in the county.
If the wall leans, the engineer's choice between bracing and rebuilding is carried out, and counterflashing over the roofing completes the roof side of the Westchester parapet.
North of the city line, no rule sets the standard for parapet work, so the standard is the one the contractor brings to the roof.
Stone, precast, brick or metal, a Westchester coping is reset or replaced in the material the building needs.
Counterflashing over the roofing is part of the job, so the inner face of a Westchester parapet is not left to fail.
Whether a leaning Westchester parapet is braced or rebuilt is settled with an engineer, and bracing comes first when it will hold.
Yonkers is Westchester’s largest city and shares a border with the Bronx, but it sits outside New York City’s parapet rule. Parapet repair in Yonkers is handled on this page, from resetting copings over new flashing to bracing or rebuilding a leaning wall with an engineer, and southwest Yonkers, with its flat-roofed apartment houses, is where many of those parapets stand.
A check of the wall on its own is covered under parapet wall inspection Yonkers, and the rest of our work in the city is on our Yonkers page.
Most of the county’s parapets are on the flat-roofed buildings of Yonkers, Mount Vernon, New Rochelle, White Plains, Port Chester and Peekskill, and we take on parapet wall restoration in every Westchester city, town and village listed below.
Inside New York City, parapet work in Manhattan, Brooklyn, Queens and the Bronx is covered on our parapet wall repair NYC page.

No. The yearly parapet observation in 1 RCNY §103-15 applies inside the five boroughs only, so Westchester and Yonkers buildings fall outside it. Check with your local building department for anything that applies where you are, since requirements vary by city and village.
Mostly flat-roofed ones. Apartment houses and older commercial blocks in Yonkers, Mount Vernon, New Rochelle, White Plains, Port Chester and Peekskill carry most of the county’s parapets. A house with a pitched roof usually has none, and a leak near its eaves is a job for roof repair in Westchester rather than masonry.
Yes. Yonkers parapets are covered by this page, since the city sits in Westchester County, and the work runs from copings and flashing to bracing or rebuilding a leaning wall with an engineer. Yonkers also borders the Bronx, but New York City’s yearly parapet rule stops at that line.
Usually the one with the fewest joints, fixed the right way for its material. Brick Industry Association guidance notes that brick copings need more joints, which gives water more ways in. Stone and precast can be fixed rigidly, while metal must be left room to move on a Westchester roof.
No. An inspection finds out what is wrong with the wall, and repair is the work that fixes it, from resetting copings over new flashing to bracing or rebuilding a leaning section. Many Westchester owners go straight to repair once a leak shows, while others want the wall looked over first, and we carry out both.
Because the water may not be coming through the roof at all. A parapet takes rain on its coping, and water that gets in through an open coping joint or a missing run of flashing runs down inside the wall, past a brand new membrane. On a Westchester flat roof, a new roof and a dry parapet are two separate jobs.
Protect the sidewalk first, then repair. Outside New York City there is no city deadline driving the work, so the owner sets the pace, but a loose coping or a leaning section above a Westchester street needs fencing off and fixing straight away, before a piece comes down.
If you want the background first, our guide on what a parapet wall is covers what a parapet does and the forms it takes on flat-roofed buildings.
Stone copings and trim that have cracked or worn away are also repaired under stone repair and repointing Westchester.
Worn mortar joints across the rest of a Westchester building are handled under brick pointing Westchester.
The rest of our brick and masonry work across the county is on our brickwork contractor Westchester page.
