You get a flat roof system built to last 15-30 years, not 5-10 like the quick fixes you see everywhere else. No more emergency calls during storms. No more water damage eating through your ceiling and walls. No more sleepless nights wondering if your roof will hold up.
When we install EPDM, TPO, or modified bitumen roofing on your Mount Sinai property, you’re investing in molecular welding technology that creates seamless, weather-tight protection. Your roof becomes a barrier that actually works against Long Island’s brutal winters, humid summers, and coastal winds.
The result? You stop worrying about your roof and start using that flat space for what it’s meant for – HVAC equipment, solar panels, or even a rooftop garden that adds value to your property.
Expressway Roofing and Chimney Inc has been protecting Suffolk County properties for over two decades. We’ve seen what Hurricane Sandy did to roofs that weren’t properly installed. We’ve repaired the damage from ice dams that formed because drainage wasn’t designed right.
That’s why we only use commercial-grade materials and installation methods that account for Mount Sinai’s specific challenges. Salt air from the coast. Temperature swings that crack inferior materials. Snow loads that test every seam and fastener.
We’re not the cheapest option in Mount Sinai – and that’s exactly why you should choose us. You’re not paying for marketing or fancy trucks. You’re paying for expertise that prevents problems before they start.
First, we inspect your existing roof structure and identify any drainage issues, structural concerns, or areas where previous work failed. No surprises halfway through the project.
Next, we remove old materials completely – no shortcuts or “roof-overs” that create problems down the road. We inspect and repair the deck, ensuring it’s structurally sound and properly sloped for drainage.
Then comes installation of your new flat roofing system. Whether it’s EPDM rubber roofing, TPO, or modified bitumen, we use heat welding and proper adhesion techniques that create permanent seams. Every penetration gets properly flashed. Every edge gets secured with mechanical fasteners and sealed with compatible materials.
Finally, we test the entire system for leaks and provide you with detailed photos of the completed work. You get a roof that’s ready for whatever Long Island weather throws at it.

We handle every type of flat roofing project in Mount Sinai – from small residential additions to large commercial buildings. EPDM rubber roofing for maximum flexibility and longevity. TPO systems for energy efficiency and UV resistance. Modified bitumen for heavy-traffic areas that need extra durability.
Mount Sinai’s coastal location means your roof faces unique challenges. Salt air accelerates material breakdown. Thermal cycling from temperature swings stresses seams and fasteners. Ice dams form when drainage isn’t properly designed for our climate.
That’s why we don’t just install roofing – we engineer solutions. Proper insulation placement to prevent ice dams. Tapered insulation systems that eliminate standing water. Redundant drainage that handles even the heaviest Long Island storms. Every detail designed specifically for our local conditions.
You also get flat roof coating services that extend your roof’s life and improve energy efficiency. Leak detection using infrared technology that finds problems before they become emergencies. And 24/7 emergency repair service when storms don’t wait for business hours.
A properly installed flat roof in Mount Sinai typically lasts 15-20 years with EPDM or TPO systems, and up to 30 years with premium modified bitumen applications. The key is professional installation that accounts for Long Island’s specific weather challenges.
Many flat roofs fail within 5-10 years because contractors don’t properly address drainage, use inferior materials, or skip critical steps like proper seam welding. When we install flat roofing, we use commercial-grade materials and installation techniques designed for coastal climates with temperature extremes, high winds, and salt air exposure.
Regular maintenance extends this lifespan significantly. We recommend bi-annual inspections and prompt repair of any issues to prevent minor problems from becoming major failures.
The most common cause of flat roof leaks in Mount Sinai is failed flashing where the roof meets walls or around penetrations like vents and HVAC units. Long Island’s freeze-thaw cycles stress these connections, while salt air accelerates material breakdown.
Standing water is another major issue. If your roof doesn’t have proper slope or drainage becomes blocked, water sits for more than 24-48 hours and permanently damages the membrane. This voids manufacturer warranties and leads to expensive structural repairs.
Poor installation practices also cause premature failures. Seams that aren’t properly welded, inadequate fastening, or using materials not designed for our climate all lead to leaks. That’s why choosing an experienced local contractor who understands Mount Sinai’s specific challenges is crucial.
If your flat roof is less than 10 years old and has isolated damage, repair is usually the most cost-effective option. We can patch small areas, re-seal penetrations, or address drainage issues without full replacement.
However, if you’re seeing multiple leaks, widespread membrane damage, or your roof is approaching 15-20 years old, replacement makes more financial sense. Repeated repairs on an aging system often cost more than a new installation over time.
We provide honest assessments based on your roof’s actual condition, not what generates the most revenue. Sometimes a targeted repair buys you several more years. Other times, replacement is the only way to stop ongoing problems and protect your property investment.
EPDM (rubber roofing) is extremely flexible and comes in large sheets up to 20 feet wide, minimizing seams. It’s black, which can increase cooling costs but provides excellent durability in cold climates. EPDM typically lasts 20-30 years and handles thermal movement well.
TPO is white, reflecting heat and reducing energy costs. It’s lighter weight and uses heat-welded seams that create permanent bonds. TPO works well in Mount Sinai’s climate and typically costs less than EPDM while providing good longevity.
Modified bitumen uses multiple layers and can handle foot traffic better than single-ply systems. It’s ideal for roofs with HVAC equipment or other heavy installations. Installation involves heat application, creating strong adhesion and weather resistance.
Flat roof replacement in Mount Sinai typically ranges from $3,000 to $10,000 depending on size, material choice, and complexity. A basic EPDM system on a simple rectangular roof costs less than a TPO system with multiple penetrations and complex drainage.
Factors affecting cost include complete removal of old materials, structural repairs, insulation upgrades, and the number of penetrations requiring custom flashing. We don’t do “roof-overs” that create problems – we remove everything and start with a solid foundation.
The investment pays off through eliminated leak repairs, lower energy costs, and extended building life. We provide detailed written estimates that break down all costs, so you understand exactly what you’re getting for your investment.
Yes, we provide 24/7 emergency flat roof repair throughout Mount Sinai and Suffolk County. When storms damage your roof or leaks threaten your property, we respond quickly to minimize damage and protect your building.
Emergency repairs include temporary patching, tarp installation, and water diversion to prevent further damage while permanent repairs are scheduled. We carry materials and equipment to handle most emergency situations on the first visit.
Our goal is stopping damage immediately, then scheduling proper permanent repairs when weather permits. Emergency service costs more than scheduled work, but it’s often much less expensive than allowing water damage to spread through your building’s structure and contents.
