Emergency repair, inspection, maintenance and replacement for commercial low-slope roofs. Staten Island owners and managers can call at any hour.
$2M general liability insurance
Staten Island’s commercial roofs don’t look like Manhattan’s. The North Shore along the Kill Van Kull is industrial: big flat roofs on warehouses and yards, often carrying heavy rooftop equipment. Richmond Avenue and Forest Avenue bring retail and office buildings, and the borough also has schools, medical buildings and civic properties.
What most of them share is exposure. The island’s waterfront and exposed sites can face strong wind and wind-driven rain, which puts attention on flashings, parapet caps and edge metal. On a survey, those are the first places we look.
Access takes planning too. Crews and material come over the bridges, so we plan deliveries and staging around the trip and the site. Send the building address and a photo of the problem, and we’ll tell you whether it needs repair, a survey or emergency service.
This service is for commercial and institutional buildings on Staten Island: warehouses on the North Shore, retail and offices along the main corridors, schools, medical and civic buildings. We repair active leaks, survey roof condition, run maintenance visits and replace low-slope systems once repairs stop holding.
Tell us the building address and what you see on the roof or on the ceiling below it. We match the problem to the right service and answer with the next step.
The right response depends on whether the roof needs an immediate fix, ongoing care, or a larger repair plan.
We find where water enters, repair it and document the fix.
Leaking now? Call the emergency line, answered day or night.
Planned visits that keep drains clear and seams sound.
Full low-slope re-roofs when repairs no longer hold.
A written condition report on the whole roof, including edges, flashings and drains, the spots wind and storm rain hit first.
Snow cleared and drains opened on commercial flat roofs through winter.
Roof loads cleared and drains kept open through winter.
Send the building address and tell us what you’re seeing, on the roof or on the ceiling below it. We’ll point you to the right next step. Commercial roofing since 2004, $2M general liability, OSHA safety standards, and MBE, DBE and LBE certified.
Yes. Our work covers commercial and institutional low-slope roofs, including warehouses, retail, offices and public buildings. We do not take residential roofing.
Exposed sites take more wind, and wind-driven rain can put particular pressure on flashings, parapet caps and edge metal. After a major storm, check for lifted seams, loose edge metal and clogged drains. If you find any, book a survey before the next rain.
Yes, at (646) 851-3145, day or night. Describe what you see and give us the Staten Island building address, and we’ll route an active leak to emergency repair.
Move stock and equipment away from the drip and place containment under it. Switch off power to any light or outlet the water touches. Keep people clear of sagging tiles, and stay off the roof. Then call (646) 851-3145.
Water travels along the roof deck, insulation and structural members before it drops through the ceiling. The stain marks where water exits, not always where it enters. A survey helps trace the water path back toward the failed seam, flashing or penetration, so the repair can address the likely source.
Ponding comes from blocked drains, low spots in the deck or a roof that has settled. Standing water adds weight, speeds up membrane wear and finds weak seams. Persistent ponding after rain points to a drain or drainage-slope problem worth surveying.
Repair fixes a defect that already exists, such as a leak or a torn seam. Maintenance is scheduled work that prevents defects: clearing drains, checking flashings, resealing small failures. Regular maintenance can identify drainage, flashing and membrane problems before they become larger repair issues
Look for brown or yellow ceiling stains, bubbling paint, sagging or discolored ceiling tiles, damp insulation and a musty smell near exterior walls. Any of these after rain justifies a survey, even when the roof looks fine from the ground.
Snow adds load and buries drains, and freeze-thaw cycles open small cracks and seams. Meltwater then refreezes in the gaps. Snow removal and a pre-winter drain check reduce the risk of leaks in the thaw.
We carry $2M general liability insurance, and crews work to OSHA standards. Share any insurance or site requirements with the building address before work starts.
MBE stands for Minority Business Enterprise, DBE for Disadvantaged Business Enterprise and LBE for Local Business Enterprise. The company holds all three, which matters to buyers who track supplier diversity or local participation.
Have the building address, a description of what you see, and photos if you can take them safely. Note where water shows inside and when it started. Those details let us point you to repair, inspection or emergency service straight away.
Yes. Interior roof repair covers ceiling and deck damage from water entry. Fixing the roof and the damage together stops the leak from returning through a repaired ceiling.
