Water stains on your ceiling and peeling paint after heavy rain are signs of leaks that can lead to mold growth and long-term structural damage. When your flat roof is properly installed with the right materials, you get complete protection from Long Island’s coastal storms and temperature swings.
Standing water that remains after 24 to 48 hours will permanently destroy your roof in these areas and void any manufacturer’s warranty. Our properly sloped installations with quality drainage prevent these costly issues.
You’ll save on energy bills year-round. TPO helps keep the heat inside during winter, reducing heating costs, while its reflective surface keeps buildings cooler in summer by bouncing off sunlight.
Expressway Roofing & Chimney has served Long Island’s roofing needs for two decades, providing the highest quality products plus professional service from over 20 years of meeting Long Island’s home improvement needs. We’re not just another roofing company—we’re your neighbors who understand exactly what Suffolk County weather does to flat roofs.
As a fully-licensed, bonded and insured home contracting company in Nassau and Suffolk County, NY, we’re more than capable of taking care of all of your roofing needs. Coastal storms in Suffolk County often leave roofs with missing materials, cracked flashing, or damaged components, weakening their protective capabilities. We’ve seen it all and know how to build systems that handle whatever nature throws at them.
First, we inspect your existing roof structure and discuss your specific needs during a free consultation. Almost all leaks are from incorrectly installed or missing penetration and wall flashings, which happens when contractors cut corners on flashing after the field of the roof is installed. We never skip the details that matter most.
Next, we prepare the surface properly and install your chosen material—whether that’s TPO, EPDM, or modified bitumen. Even the best roofing material available can fail if it’s not properly installed, which is why it’s important to hire a contractor with the resources to complete a first-class installation.
Finally, we handle all the critical finishing work: proper flashing around penetrations, adequate drainage systems, and thorough quality checks. Knowing how your roof is being finished is more important than the roof itself, because this is where water intrusion usually comes from. You get a complete system that’s built to last, not just look good on day one.

Our technicians are trained and certified to install complete roof systems with warranties ranging from 15 years to over 30 years using TPO, EPDM, Modified Bitumen, and Silicone roof coating. Each material has specific advantages depending on your building’s needs and your priorities.
EPDM flat roofing is the most popular choice for residential flat roofs because this black, rubber-like material won’t get visibly dirty. TPO is a popular choice for flat roofs because it’s durable and energy-efficient, with its reflective surface helping keep buildings cool in summer, reducing energy costs.
Modified bitumen works well on residential and small-scale commercial flat roofs because it comes in 3-foot-wide rolls, making it easy to handle and apply by rolling out the material so seams overlap, with seams fused with a torch or sealed with special adhesive. In Yaphank’s climate, each material performs differently, and we’ll help you choose what makes the most sense for your specific situation and budget.
Depending on the product, quality of installation, and preventative roof maintenance, EPDM can last 20-50 years. The lifespan really depends on three things: the material you choose, how well it’s installed, and how it’s maintained over time.
In Suffolk County’s coastal climate, properly installed TPO and EPDM systems typically last 20-30 years with regular maintenance. Modified bitumen systems can also provide excellent longevity when installed correctly. The key is starting with quality materials and professional installation—cutting corners upfront always costs more in the long run.
Weather plays a big role here too. Coastal storms in Suffolk County often leave roofs with damaged components, weakening their protective capabilities. That’s why choosing materials and installation methods designed for our local conditions makes such a difference in actual performance.
Almost all leaks are from incorrectly installed or missing penetration and wall flashings, which happens when contractors cut corners on flashing after the field of the roof is installed. It’s not usually the roofing material itself that fails—it’s the details around vents, HVAC units, and roof edges.
Door access panels, seams in HVAC ducts, and pitch pockets contribute to 50% of commercial roof leak repairs, while roof perimeter coping and roof drains account for 40% of service calls, with only 10% of leaks resulting from failed roofing. The lesson here is that proper flashing and detail work is absolutely critical.
Standing water is also a big problem, defined by industry standard as water present 24 to 48 hours after moderate weather conditions. If water is still present after a day or two, this will permanently destroy your roof in these areas and void any manufacturer’s warranty. Proper drainage design prevents this issue entirely.
EPDM flat roofing is the most popular choice for residential flat roofs because it doesn’t easily get dirty since it’s black, unlike TPO which gets dirty easily over time and requires constant maintenance. For most homeowners, EPDM offers the best balance of performance and low maintenance.
EPDM provides heating and energy benefits because it absorbs the sun, causing the room below to feel warmer in hotter seasons, which can be useful for rooms that are hard to heat, like sunrooms and large living rooms. If you prefer a reflective surface, EPDM also comes in white, while TPO roofing is white and reflects the sun rather than absorb it.
The choice really depends on your specific situation: the size of the roof, your energy priorities, and your maintenance preferences. We’ll walk you through the pros and cons of each option based on your actual needs, not just push the most expensive material.
A re-roof with minimal penetrations and walls and an 8-year warranty will cost about $2.50 to $3.50 per square foot. However, costs vary significantly based on several factors: the size of your roof, how many penetrations (vents, HVAC units) need flashing, and whether we’re doing a complete tear-off or installing over existing materials.
Complete tear-off projects can cost between $9 and $20 per square foot, depending on size, height, layout, and specifications. Sometimes maintaining the existing membrane and applying coatings can extend the roof’s life, avoiding the need for disruptive and costly replacement, costing between $5 and $8 per square foot with manufacturer warranties of up to 20 years.
The most accurate way to get pricing is with a free inspection where we can see exactly what we’re working with. We’ll give you options at different price points so you can make the choice that fits your budget and long-term plans.
