TPO Roofing Installation in Long Island, NY

Why TPO Dominates Commercial Applications

TPO roofing has become the gold standard for flat and low-slope applications in Suffolk County, and there’s a reason why. The heat-welded seams create molecular bonds that are actually stronger than the membrane itself – something you can’t get with EPDM’s glued connections.

We see the difference every day. While EPDM seams start failing after 10-15 years, properly installed TPO systems maintain their integrity for decades. The white reflective surface cuts cooling costs dramatically, especially important with Long Island’s humid summers. And unlike PVC, TPO delivers that performance without the premium price tag.

EPDM Rubber Roofing Suffolk

When Flexibility Matters Most

EPDM rubber roofing excels in situations where thermal movement and flexibility are critical. For Suffolk County properties with complex roof lines, multiple penetrations, or structures that experience significant expansion and contraction, EPDM’s rubber composition handles the stress without cracking.

We typically recommend EPDM for residential applications, smaller commercial buildings, and anywhere aesthetics require a black membrane. The material comes in wider sheets than TPO, meaning fewer seams and fewer potential failure points. With proper installation and a reflective coating, EPDM systems regularly deliver 30+ years of reliable service.

Flat Roofing FAQs

Common questions about Flat Roofing

The lifespan depends entirely on the material and installation quality. EPDM systems typically last 20-30 years, while TPO can go 25-35 years with proper maintenance. Modified bitumen usually provides 15-25 years of service. However, we’ve seen poorly installed roofs fail within 5-10 years, especially when contractors cut corners on seam welding or flashing details. Our installations regularly exceed these timeframes because we follow manufacturer specifications exactly and use commercial-grade materials even on residential projects.
TPO uses heat-welded seams that create molecular bonds stronger than the membrane itself, while EPDM relies on adhesive-bonded seams that can fail over time. TPO is naturally white and reflective, reducing cooling costs, while EPDM is black and absorbs heat unless you add a reflective coating. TPO works better for larger commercial applications, while EPDM excels in residential settings and areas requiring flexibility. Cost-wise, TPO runs slightly higher upfront but often provides better long-term value due to energy savings and durability.
Flat roofs don’t actually leak more when properly installed – they just show problems faster because water can’t run off as quickly. The main issues are poor drainage design, inadequate slope, and failed flashing at penetrations or perimeter edges. Many contractors don’t understand that “flat” roofs still need proper slope for drainage, typically 1/4 inch per foot minimum. We see most leak problems at roof-to-wall transitions, around HVAC units, and at drain locations where flashing wasn’t installed correctly.
Costs vary significantly based on material choice, roof complexity, and existing conditions. EPDM typically runs $4-$9 per square foot installed, TPO ranges $5-$10 per square foot, and modified bitumen falls between $4-$8 per square foot. These prices include removal of existing materials, new insulation if needed, and proper flashing installation. Factors that increase costs include multiple roof levels, numerous penetrations, structural repairs, and accessibility challenges. We provide detailed estimates that break down all costs so you know exactly what you’re paying for.
Proper maintenance is surprisingly minimal with quality installations. You should clear drains and gutters twice yearly, remove debris that could puncture the membrane, and inspect flashing around penetrations annually. Professional inspections every 2-3 years help catch minor issues before they become major problems. Most importantly, address any ponding water immediately – standing water for more than 48 hours will void most manufacturer warranties and accelerate membrane deterioration. We provide maintenance programs that handle all these requirements automatically.
