Your flat roof should be invisible to you. No surprise leaks during the next heavy rain. No water stains spreading across your ceiling. No emergency calls to multiple contractors who can’t figure out where the problem is coming from.
When we’re done, you’ll have a properly installed flat roofing system that handles everything Long Island weather throws at it. TPO, EPDM, or modified bitumen – whatever your building needs, installed right the first time.
You’ll sleep through storms instead of listening for drips. Your energy bills will drop because your roof actually reflects heat instead of absorbing it. And when you need maintenance or have questions, you’ll have a local team that knows your roof and shows up when we say we will.
Expressway Roofing and Chimney Inc has been handling flat roof challenges across Suffolk County for years. We’re not the guys who usually do shingles and decided to try flat roofing last week.
Flat roofs are different. The materials are different. The installation process is different. The potential problems are different. We’ve seen every type of flat roof failure that happens in this area – from membrane shrinkage in our hot summers to ice dam issues in winter.
Most importantly, we’re local to Greenlawn and understand what works here. Long Island’s coastal climate, temperature swings, and building styles create specific challenges that require specific solutions.
First, we inspect your current roof situation and explain what’s actually going on up there. No sales pitch – just a clear assessment of what needs to happen and why.
Next, we handle all the prep work. That means proper substrate preparation, insulation upgrades if needed, and ensuring proper drainage. Most flat roof problems start with shortcuts during this phase.
Then comes the installation using the right materials for your specific building and budget. Whether that’s TPO for energy efficiency, EPDM for durability, or modified bitumen for specific applications, we install it according to manufacturer specifications.
Finally, we walk you through the completed system, explain maintenance requirements, and provide you with warranty information. You’ll know exactly what to expect from your new flat roof and how to keep it performing for decades.

Complete flat roof replacement with your choice of TPO, EPDM, or modified bitumen systems. Professional leak detection using electronic scanning equipment when repairs are needed. Emergency flat roof repair services when you can’t wait for regular scheduling.
In Greenlawn, we see a lot of flat roofs on commercial buildings along Route 25A and Pulaski Road, plus residential flat roof sections on modern homes and additions. Each situation requires different approaches based on the building’s use, age, and exposure to Long Island’s weather patterns.
We also provide flat roof coating applications to extend the life of existing systems, and comprehensive maintenance programs to catch small issues before they become expensive problems. Everything includes proper permits and inspections to meet Suffolk County requirements.
Most residential flat roof replacements take 1-3 days depending on the size and complexity of your roof. Commercial projects can take longer based on square footage and access requirements.
Weather is the biggest variable here on Long Island. We won’t install your flat roofing system in wet conditions because moisture trapped under the membrane creates long-term problems. We’ll give you a realistic timeline upfront and keep you updated if weather delays occur.
The actual installation moves quickly once we start. The time-consuming part is usually the prep work – removing old materials, fixing substrate issues, and ensuring proper drainage slopes.
TPO (Thermoplastic Polyolefin) performs exceptionally well in our climate. It reflects heat during hot summers, handles temperature fluctuations without cracking, and resists the UV exposure we get here on the coast.
EPDM rubber roofing is another solid choice, especially for buildings that need maximum durability. It’s been proven in harsh climates and handles our winter freeze-thaw cycles without issues.
Modified bitumen works well for specific applications, particularly where you need extra puncture resistance or have unusual roof configurations. We’ll recommend the best option based on your building’s specific needs, not what we happen to have in the truck.
We use electronic leak detection equipment that can pinpoint exactly where water is entering, even when the leak location isn’t obvious from inside the building. Water can travel along the roof deck before dripping down, making visual inspection unreliable.
The electronic scanning process involves placing sensors on the roof membrane and using electrical current to identify compromised areas. This eliminates guesswork and prevents us from making unnecessary repairs in the wrong locations.
We also perform thorough visual inspections of all penetrations, seams, and drainage areas. Most flat roof leaks occur at these predictable failure points, and experienced eyes can spot potential problems before they become active leaks.
Yes, regular maintenance is essential for flat roof longevity, especially with Long Island’s weather extremes. We recommend professional inspections twice yearly – once after winter to check for ice damage, and once in fall to prepare for the next winter season.
Drainage maintenance is critical here because our heavy rains can overwhelm clogged drains quickly. We clean all drains and scuppers, and check that water flows properly to prevent ponding that can stress the membrane.
We also inspect and maintain all roof penetrations, flashings, and seams. Small issues caught early cost much less to fix than emergency repairs during a storm. Our maintenance programs keep your warranty valid and extend your roof’s service life significantly.
Minor repairs like sealing small punctures or fixing loose seams typically run $200-500. Larger repairs involving membrane replacement or substrate work can range from $500-2000 depending on the area and complexity.
Emergency repairs during storms cost more because of the urgency and working conditions, but we try to keep emergency pricing reasonable. We’d rather fix your roof properly than have you deal with ongoing water damage.
The key is catching problems early through regular maintenance. A $300 repair today prevents a $3000 emergency replacement next year. We always provide detailed estimates before starting work so you know exactly what you’re paying for.
Absolutely. We install flat roofing systems on residential properties throughout Greenlawn, including modern homes with flat roof sections, additions, garages, and covered porches or decks.
Residential flat roof installations require the same attention to detail as commercial work, just on a smaller scale. We ensure proper insulation, ventilation, and drainage to prevent ice dams and condensation issues common in residential applications.
Many homeowners choose TPO for residential flat roofs because of its energy efficiency and clean appearance. We handle all permits and inspections required by Suffolk County for residential flat roofing projects, and our warranties are the same whether it’s a house or a commercial building.
