Hear from Our Customers
You get a flat roof system that handles everything East Hampton weather throws at it. No more emergency buckets during storms. No more wondering if this winter will be the one that finally causes major damage.
Your energy bills drop because proper flat roofing installation includes the insulation and reflective materials that actually work. You’re not heating the outdoors or running your AC overtime to fight heat absorption from a poorly designed roof.
Most importantly, you sleep better knowing your roof was installed right the first time. Our EPDM, TPO, and modified bitumen systems are built for Long Island’s freeze-thaw cycles, coastal humidity, and everything in between.
Expressway Roofing and Chimney Inc has been solving flat roof problems in East Hampton for over 20 years. We’ve seen what works and what fails when Long Island weather gets serious.
We’re not the contractors who disappear after the job. We’re the ones East Hampton property owners call when they need flat roofing done right. Our team understands local building codes, knows which materials perform best in coastal conditions, and has the experience to spot problems before they become expensive disasters.
East Hampton’s unique position on Long Island means your roof faces salt air, heavy snow loads, and temperature swings that can destroy inferior installations. We build flat roofing systems that handle all of it.
First, we inspect your existing roof structure and identify any drainage issues or structural concerns. Most flat roof failures start with problems that should have been caught during the initial assessment.
Next, we prepare the surface properly. This means addressing any moisture issues, ensuring proper slope for drainage, and creating the foundation your new flat roofing system needs to perform for decades.
Then comes the installation. Whether you choose EPDM rubber roofing, TPO membrane, or modified bitumen, we use heat welding and molecular bonding techniques that create seamless, waterproof barriers. No shortcuts, no hoping the seams hold up over time.
Finally, we test the entire system and show you exactly what we’ve done. You get documentation of materials used, warranty information, and maintenance recommendations specific to East Hampton’s climate conditions.

EPDM rubber roofing remains the most popular choice for East Hampton residential flat roofs. This synthetic rubber membrane can last 50+ years in Long Island conditions and handles freeze-thaw cycles without cracking. Black EPDM absorbs heat in winter, helping reduce heating costs, while white EPDM reflects summer heat.
TPO roofing offers superior energy efficiency with its reflective white surface and heat-welded seams. The molecular welding process creates bonds stronger than the membrane itself, eliminating the weak points that cause most flat roof failures. TPO performs exceptionally well in East Hampton’s coastal environment.
Modified bitumen provides the durability of traditional built-up roofing with modern installation techniques. The heat-applied membranes create multiple layers of protection, ideal for commercial applications or residential properties with high foot traffic.
All our flat roofing systems include proper insulation, drainage design, and flashing details specific to East Hampton building codes and weather patterns. You’re not just getting a roof covering – you’re getting a complete system engineered for local conditions.
Quality flat roofing systems last 20-50 years in East Hampton, depending on the material and installation quality. EPDM rubber roofing typically provides 30-50 years of service life, while TPO systems last 20-30 years with proper maintenance.
The key factor isn’t just the material – it’s how well the system handles Long Island’s specific challenges. Freeze-thaw cycles, salt air, and heavy snow loads can dramatically reduce lifespan if the installation doesn’t account for these conditions.
Our installations include proper drainage design, adequate insulation, and flashing details that prevent the most common failure points. Most flat roof replacements we see are due to installation shortcuts, not material failure.
EPDM is a synthetic rubber membrane that’s extremely flexible and handles temperature changes without cracking. It comes in black (which absorbs heat) or white (which reflects heat) and uses adhesive bonding at seams.
TPO is a thermoplastic membrane that’s heat-welded at all seams, creating molecular bonds stronger than the material itself. TPO is naturally white and reflects more heat than black EPDM, making it more energy-efficient for cooling costs.
For East Hampton properties, EPDM works better when you want heat absorption in winter, while TPO excels when energy efficiency and cooling costs are priorities. Both materials handle coastal conditions well, but TPO’s welded seams provide superior long-term waterproofing in areas with frequent temperature cycling.
Proper drainage design is critical for flat roof performance in East Hampton. We create slight slopes (minimum 1/4 inch per foot) toward strategically placed drains, even on “flat” roofs.
During installation, we use tapered insulation systems that direct water flow and prevent the low spots where ponding typically occurs. All drain areas get reinforced with additional membrane layers and proper flashing details.
We also install overflow drains and scuppers as backup systems. East Hampton’s heavy rainstorms and snow melt can overwhelm primary drains, so secondary drainage prevents water backup that leads to leaks. Regular maintenance includes keeping drains clear and checking that water flows properly during storms.
Most flat roof leaks occur at penetrations and transitions, not in the main membrane area. HVAC units, vent pipes, and roof edges account for about 90% of the leak calls we receive in East Hampton.
Poor flashing installation where the roof meets walls or parapets is another major problem. Many contractors use tar-based sealants that fail within a few years instead of proper membrane flashing that integrates with the roofing system.
Drainage problems cause the remaining leaks. When water pools on flat roofs, it finds weak spots in seams and eventually works through the membrane. Proper slope design and drain maintenance prevent most of these issues, but many flat roofs are installed without adequate drainage planning.
Sometimes, but it depends on the condition of the existing roof and local building codes. East Hampton building codes allow up to two layers of roofing in most cases, but adding a third layer requires complete removal to the deck.
We perform thorough inspections to check for moisture damage, structural integrity, and proper ventilation before recommending overlay installation. If the existing roof has any moisture damage or structural issues, removal is necessary for a lasting repair.
Overlay installations can save money initially, but they add weight to the structure and can hide problems that worsen over time. For most East Hampton properties, complete removal and replacement provides better long-term value and performance, especially when dealing with older roofing systems.
Flat roof replacement typically costs $12-20 per square foot in East Hampton, depending on the material choice, roof size, and complexity. EPDM systems are generally less expensive than TPO, while modified bitumen falls in the middle range.
Factors affecting cost include removal of existing materials, structural repairs, insulation upgrades, and drainage modifications. Properties requiring crane access or having multiple penetrations cost more due to additional labor complexity.
We provide detailed estimates that break down material and labor costs so you understand exactly what you’re paying for. Most East Hampton flat roof projects include 15-25 year warranties on materials and workmanship, making the investment worthwhile compared to repeated repair costs on failing systems.
