What NYC building owners say

Luis and his terrific L.A. New York Restoration team did work on our home with a level of skill, efficiency, and care we haven't experienced before. They removed and rebuilt our rotted back steps, patched, painted, and repaired the steel faux-tile roof, and pointed and sealed both the front and back walls. Scaffolding was used for safety. They were always on time – often early, extremely neat, and very careful. I never felt I had to oversee or manage anything. Their professionalism and experience were obvious in every step. We couldn't be more pleased with the results.

As a contractor who manages multiple renovation projects in NYC and Queens, I regularly work with LANY Restoration Corp for roofing, waterproofing, and exterior facade restoration. Luis and his team are one of the most reliable crews I've worked with. They are always professional, show up on time, and consistently deliver high-quality workmanship. On every project we've done together, they have stayed on schedule and completed the work exactly as planned. The roofing, waterproofing, and facade work they perform is top quality. I highly recommend them to homeowners and contractors looking for professional roofing and facade work.

Our Approach

Methodical parapet restoration

Parapet repair starts with understanding the full assembly — masonry, flashing, coping, counterflashing, and the roof tie-in. We assess each component to determine whether repair, partial rebuild, or full reconstruction is warranted.

When reconstruction is required, we rebuild with proper through-wall flashing, compatible mortar, adequately anchored coping, and a detailed tie-in to the roofing system. Every component works together — a new coping on failed flashing just moves the leak.

Parapet walls: the most vulnerable part of your building

Parapet walls are exposed on three sides to weather — front, back, and top. They absorb more water, endure more freeze-thaw cycles, and experience more thermal movement than any other part of your facade. They're also where your roof terminates, making them critical to both facade integrity and waterproofing.

When parapets fail, the damage cascades. Water enters through deteriorated coping joints, saturates the wall core, corrodes embedded steel, and migrates into the roof system and interior spaces. A crumbling parapet isn't just a masonry problem — it's a building envelope failure.

Common Issues

Common parapet failure modes

Coping Stone Failure

Parapet coping stones shift, crack, and lose their mortar joints. Once the cap is compromised, water enters the wall from the top — the most damaging infiltration path.

Through-Wall Flashing Deterioration

Parapet flashing that diverts water out of the wall assembly degrades over time. When it fails, water migrates downward through the wall core unchecked.

Mortar Joint Erosion

Three-sided exposure accelerates mortar deterioration. Parapets often need repointing decades before the main facade below.

Structural Movement

Thermal cycling causes parapets to lean, bow, or separate from the roof structure. Severe cases require partial or full reconstruction.

Local Law 126 Parapet Repairs

When an annual Local Law 126 observation flags a parapet, we do the repairs it calls for: parapet coping reset or replaced, parapet flashing rebuilt, joints and brick repaired, and photos for your file. We do not perform the observation itself.

Maintenance

Parapet maintenance prevents cascade failures

Parapets deteriorate faster than the rest of your facade. Targeted maintenance extends their service life significantly.

✓Mortar joint monitoring on both faces of the parapet

FAQ

Frequently Asked Questions

Targeted repairs (coping replacement, localized repointing, flashing) typically run $6,000–25,000. Full parapet rebuilds — common on older masonry buildings with extensive deterioration — run $40,000–150,000+ depending on building size and access. We provide line-item scopes after assessment.
Loose or displaced coping stones, eroded mortar joints, leaning walls, rust staining, and water infiltration at the roof edge are common indicators.
It depends on the extent of deterioration. Mortar repointing and coping replacement are common repairs. Severely deteriorated or leaning parapets may require partial or full reconstruction.
Yes. Deteriorated parapets are among the most common FISP findings. Unsafe conditions require repair within DOB-mandated timelines.
Local Law 126 of 2021 and DOB rule 1 RCNY §103-15 require owners to have parapets observed every year where they front a public right-of-way, such as a street or sidewalk, regardless of the building's height. Detached one- and two-family homes are exempt. The owner keeps the observation report on file, and an unsafe condition needs public protection, such as a sidewalk shed, right away, followed by repair. We do not perform the observation; we perform the parapet wall repair it calls for and document it for the file.
Scope depends on building size and extent of deterioration. Targeted repairs may take days; full parapet reconstruction on a large building may take several weeks.
