When our Upper East Side co-op building faced a tight deadline for Local Law 11 facade repairs, Cornerstone stepped in and delivered. They handled the DOB filings, installed a sturdy sidewalk shed, and kept our storefronts completely accessible during the entire project. True professionals who know NYC code inside and out.
Working on irregular historic facades in Brooklyn requires a scaffolding partner that can customize a system on the fly. Cornerstone's crew engineered a pipe scaffolding setup that fit our tight brownstone setbacks perfectly. Fast installation, clean job sites, and zero headaches with inspectors.
We needed emergency sidewalk protection installed following an unexpected facade issue. Cornerstone mobilized immediately across the job site, secured the perimeter, and ensured our commercial tenants could stay open for business.

Isolated problem, sound roof otherwise: repair. Failures in multiple places, or membrane deteriorating broadly: replacement. We confirm which after we've actually looked.
This page covers scheduled repair: problems you can describe and wait a day or two on. If water is actively coming through right now, use the emergency link at the top of this page instead.
Yes. We hold MBE, DBE and LBE certification.
Yes. We carry $2 million in general liability coverage, and our crews follow OSHA safety standards. That matters more on repair work than on most jobs, since it's often work at height over a sidewalk or lot still in use.
We repair single-ply membranes including TPO, PVC and EPDM, as well as built-up and modified bitumen systems. If you're not sure what's on your roof, send a photo and the building address.
Repair cost depends on the roofing system, the extent of the damage and roof access (occupied building vs. vacant, loading dock vs. street level). A single failed seam repair is a very different job from a section of wet insulation removal. We give a firm number after inspection, at no charge for the look.
