You’re tired of dealing with leaks every time it rains. You’re frustrated with contractors who disappear after taking your deposit. You need a flat roof that works, installed by people who actually show up when they say they will.
That’s exactly what you get with our flat roofing systems. No more emergency buckets during storms. No more water stains spreading across your ceiling. No more wondering if this repair will actually hold.
We install TPO, EPDM, and modified bitumen systems that last decades, not years. Your energy bills drop because these roofs reflect heat instead of absorbing it. Your insurance company stays happy because your roof meets all code requirements.
Expressway Roofing and Chimney Inc has been protecting Stony Brook properties for years. We understand how nor’easters, summer storms, and freeze-thaw cycles affect flat roofs on Long Island.
Most flat roof problems happen because contractors don’t understand proper drainage or use cheap materials to boost their profit margins. We do the opposite. Every job gets commercial-grade materials and installation techniques that handle whatever weather hits the area.
You’ll work directly with licensed professionals who live and work in Suffolk County. We’re not a fly-by-night operation that disappears after the check clears.
First, we inspect your existing roof to identify all problem areas, not just the obvious leaks. Most contractors miss secondary issues that turn into expensive problems later. We document everything with photos so you see exactly what needs attention.
Next, we remove the old roofing material down to the deck if necessary. We inspect and repair the underlying structure, upgrade insulation, and install proper drainage systems. This step separates professional work from quick patches that fail within months.
Finally, we install your new flat roofing system using manufacturer-approved techniques. Every seam gets properly welded or adhered. Every penetration gets properly flashed. You get a roof that actually works, plus documentation for warranty claims if needed.
Ready to get started?
Your flat roofing project includes complete tear-off when needed, deck inspection and repairs, upgraded insulation, and proper drainage installation. We don’t cut corners on the invisible parts that make or break your roof’s performance.
Stony Brook’s coastal location means your roof faces salt air, high winds, and temperature swings that destroy inferior installations. We use TPO membranes rated for coastal environments and EPDM systems that flex with temperature changes without cracking.
Every project includes manufacturer warranties on materials plus our workmanship guarantee. You get detailed documentation for insurance purposes and maintenance schedules that keep your warranty valid. No surprises, no hidden costs, no callbacks for problems that should have been fixed the first time.
Quality TPO roofing systems last 20-30 years in Long Island’s coastal climate when properly installed. The key factors are using membrane thick enough to handle thermal expansion and ensuring all seams are properly welded, not just glued.
Cheap TPO installations fail within 5-10 years because contractors use thinner material or don’t properly prepare the surface. We use 60-mil TPO minimum and follow manufacturer specifications exactly. Your roof gets the same installation quality as commercial buildings that need to last decades.
The white TPO surface reflects heat, which reduces cooling costs and extends the membrane’s life. In Stony Brook’s humid summers, this reflection can cut your air conditioning costs by 15-20% compared to dark-colored roofing materials.
EPDM is black rubber that’s extremely durable but absorbs heat. TPO is white thermoplastic that reflects heat but requires more precise installation. Both work well for Stony Brook homes when installed correctly.
EPDM costs less upfront and handles temperature extremes better. It’s the better choice if your roof has complex shapes or many penetrations. The black surface does increase cooling costs, but the material itself lasts longer in harsh weather.
TPO costs more initially but saves money on energy bills. It’s better for simple roof shapes and new construction. The welded seams are stronger than EPDM’s glued seams, but they require specialized equipment and training to install properly.
Proper drainage starts with correct slope during installation. Even “flat” roofs need 1/4 inch of slope per foot toward drains or scuppers. Most ponding problems happen because contractors don’t create adequate slope.
We install tapered insulation systems that create positive drainage to all roof drains. This prevents water from sitting on your roof for more than 48 hours after storms. Standing water accelerates membrane deterioration and creates leak points.
For existing roofs with drainage issues, we can retrofit slope using lightweight fill or additional tapered insulation. Emergency drainage systems like overflow drains provide backup protection during heavy rains when primary drains get clogged with debris.
Poor flashing around penetrations causes 80% of flat roof leaks in Stony Brook. Vents, HVAC units, and skylights create weak points where water can penetrate if not properly sealed.
Wind-driven rain during nor’easters finds every small gap in flashing systems. We see failures where contractors used caulk instead of proper mechanical flashing or didn’t extend flashing high enough up walls and penetrations.
Thermal expansion and contraction also create problems. Long Island’s temperature swings cause roofing materials to expand and contract daily. Cheap installations crack at stress points, especially around edges and penetrations where movement is greatest.
Complete flat roof replacement typically costs $8-15 per square foot depending on material choice, roof complexity, and structural repairs needed. Simple TPO installations cost less than complex EPDM systems with multiple penetrations.
The total project cost includes tear-off, disposal, deck repairs, insulation upgrades, and new membrane installation. Many contractors give low initial quotes then add charges for “unexpected” issues that should have been identified during inspection.
We provide detailed written estimates that include all anticipated work. If we find additional problems during tear-off, we discuss options before proceeding. Most Stony Brook flat roof replacements range from $15,000-40,000 depending on size and complexity.
Yes, we provide emergency leak repairs 24/7 during severe weather events. Flat roofs can’t wait for convenient scheduling when water is actively entering your building.
Emergency repairs focus on stopping water infiltration immediately using temporary patches and tarps. Once weather permits, we return to make permanent repairs using proper materials and techniques. Quick fixes during storms prevent extensive interior damage.
We keep emergency repair materials stocked year-round and maintain relationships with suppliers for urgent material needs. During major storms, we prioritize calls based on severity and safety concerns, but we respond to every emergency within 24 hours maximum.
