What You Cannot See on Your Commercial Roof Can Cost You More Than You Think.
A commercial roof is not like a residential roof. It covers more surface area, supports more mechanical equipment, and faces more foot traffic and wear than most homeowners ever have to worry about. And in New York City, it also has to stand up to some of the toughest weather conditions in the country.
When a commercial roof starts to fail, the signs are not always obvious right away. A small leak can travel a long distance before it shows up as a water stain on the ceiling. By then, the damage has often spread to insulation, structural materials, and interior finishes. What started as a minor roofing issue has become a major disruption to your business.
That is the reality of ignoring a commercial roof. And that is exactly why so many building owners and property managers across New York City trust Gramercy Roofing to keep their roofs in top condition. We catch problems early, fix them properly, and help you put a maintenance plan in place so you are never caught off guard.

From New Installations to Emergency Repairs, We Handle Every Commercial Roofing Need
Not every commercial roof is the same. The right membrane system depends on your building type, your roof's layout, how much foot traffic it sees, and what kind of performance you need over the long term. At Gramercy Roofing, we work with a full range of commercial membrane systems so we can match the right solution to your specific property. Here is what we install and why each system matters.
Modified Bitumen
Modified bitumen is a multi-layer roofing system that delivers serious waterproofing performance for commercial rooftops that see heavy use and foot traffic. It can be installed using a torch-applied method or a cold-adhesive process depending on the building and conditions. Either way, the result is a tough, layered membrane that bonds tightly to the roof surface and resists water infiltration even under significant stress. If your commercial roof takes a beating on a regular basis, modified bitumen is built to handle it.
SIPLAST Liquid-Applied Systems
SIPLAST liquid-applied roofing is one of the most advanced commercial roofing solutions available today, and it is one that most roofing companies are not certified to install. As SIPLAST-certified installers, Gramercy Roofing is trained and approved to apply these systems correctly, which means you get the full benefit of the technology and the manufacturer warranty that comes with it. Liquid-applied systems are ideal for buildings with complex rooflines, rooftop equipment, or hard-to-reach areas where traditional membrane systems are difficult to install. The liquid coating cures into a seamless, fully bonded waterproof membrane with no seams or joints where water can penetrate. It is a clean, fast, and highly effective solution that works on roofs that other systems simply cannot handle as well.
TPO Roofing
TPO is a reflective, single-ply membrane that is designed to reduce heat absorption on large flat roofs. In a city like New York, where summer temperatures push rooftop surfaces to extreme levels, TPO helps keep energy costs down while delivering long-term durability. It is lightweight, resistant to UV rays, and holds up well against the kind of weather New York dishes out all year long. If you are looking for an energy-efficient option for a large commercial roof, TPO is one of the best choices available.
EPDM Roofing
EPDM is a rubber membrane system that has been trusted in commercial roofing for decades. It is flexible, puncture-resistant, and performs exceptionally well on warehouses, industrial buildings, and other large commercial properties. EPDM handles temperature swings well, which makes it a reliable choice for New York's climate where winters are cold and summers are hot. It is also one of the most low-maintenance commercial roofing systems available, which means lower long-term costs for building owners and property managers.

Not Sure What Your Commercial Roof Actually Needs? Start Here.
How long does a commercial roof last?
Most commercial roofing systems last between 15 and 30 years depending on the materials used, the quality of installation, and how consistently the roof is maintained. Regular inspections and preventive maintenance can add years to that lifespan.
How do I know if my commercial roof needs a repair or a full replacement?
If the damage is isolated and the roof is relatively young, a repair is usually the right call. If it is older, has widespread issues, or has been repaired repeatedly, a full replacement will save you more money over time.
Can you work around our business hours to avoid disrupting our operations?
Yes. We plan every commercial roofing project with your schedule in mind. We are happy to work during evenings, weekends, or off-peak hours to keep disruption to your business and your tenants as minimal as possible.
What is the best roofing system for a large flat commercial roof?
It depends on your building, budget, and performance needs. TPO is a strong choice for energy efficiency, EPDM works well for industrial buildings, and SIPLAST liquid-applied systems are ideal for complex rooflines. We help you choose the right fit.
How often should a commercial roof be inspected?
We recommend a professional inspection at least twice a year, typically in spring and fall, and always after a major storm. Catching small issues early is far less expensive than waiting until a minor problem becomes a major repair.
