A Bronx roof gets a service based on what sits under it. A six story walk-up in Belmont needs parapet and drain work, a Hunts Point cold-storage box needs insulation and seam attention, and a Fordham Road storefront needs flashing at the rooftop units. We start with a flat-roof walk, write down what we see, and recommend the smallest service that solves the problem. If the roof needs a larger step, the report says so and shows the evidence.
Finding the problem
A roof inspection is the base step. A drone survey covers tall or steep buildings without sending anyone to the edge, and an infrared moisture survey shows wet insulation under a membrane that looks sound. Each one ends with photos and a ranked list.
Repairs and maintenance
A tenant complaint usually points to leak repair, and most leaks trace to flashing, a clogged drain or a failed seam. Wider damage goes to roof repair, and a maintenance program clears strainers and checks details twice a year so the next work order is smaller. Storms, including the 3.15 inches of rain in one hour that Hurricane Ida dropped in 2021, are handled through storm damage repair and emergency response.
When the roof needs more
When repairs stack up, the choice is a coating, a recover or a full replacement. Core cuts decide it. Dry insulation under a tired membrane can take a coating or recover, while wet insulation has to come out. Buildings that stay open follow the sequence for occupied reroofing.
Details that cause leaks
Smaller scopes carry the most leaks: drains and scuppers, edge metal and coping, and skylight and penetration flashing. On pre-war buildings along the Grand Concourse, coping stone and counterflashing lead the list, because water that gets behind a parapet runs down the inside of the wall and shows up as a stain in a top-floor ceiling. On Hunts Point warehouses, the penetrations for refrigeration lines and rooftop units take the same role. We mark each detail on the walk and price it as its own line, so a manager can fund the small items first and plan the large ones for the next budget cycle.
Commercial Roofing Questions
Which service should a manager request first?
Request the flat-roof walk. It costs less than a wrong repair, and the report tells you whether the next step is a patch, a coating or a replacement.
Can one visit cover several buildings?
Yes. Send the address types and roof ages for each building, and the walk can rate all of them in one trip so the budget can be ranked.
Do services change for NYCHA-type towers and small retail roofs?
The steps stay the same. Towers take longer because of access and the number of penetrations, and a retail roof takes less time but still gets every drain checked.
What paperwork follows a service call?
A written report with photos, quantities and a ranked list of items. The Department of Buildings puts out the 2022 NYC codes. Paperwork starts there.
