Types of Flat Roof Materials: Which Is Right for You?
Start with the best materials, then go from there.
Choosing the Right Membrane for Your Long Island Property
Selecting the appropriate flat roofing material impacts your roof’s performance, longevity, maintenance requirements, and total cost of ownership.
County Roofing Systems installs all major flat roofing membrane types and helps Long Island property owners choose the best system for their specific needs.
TPO (Thermoplastic Polyolefin) Roofing
TPO has become the most popular choice for commercial flat roofs throughout Long Island.
This single-ply membrane features heat-welded seams that create bonds stronger than the material itself, virtually eliminating seam failures. White TPO reflects up to 87% of solar radiation, dramatically reducing cooling costs during Long Island’s hot, humid summers.
TPO membranes resist UV damage, ozone exposure, chemical exposure, punctures, and bacterial growth. The material remains flexible in cold temperatures while withstanding summer heat without deteriorating.
TPO accommodates building movement without cracking and typically lasts 25-30 years with minimal maintenance. It’s ideal for commercial buildings, large residential flat roofs, and properties prioritizing energy efficiency.
EPDM (Rubber Membrane) Roofing
EPDM rubber roofing has protected buildings for over 50 years with proven reliability and performance.
This synthetic rubber membrane handles temperature extremes from -40°F to 300°F, making it exceptionally durable in Long Island’s variable climate. EPDM resists ozone and UV radiation naturally without requiring protective coatings.
Available in black and white formulations, EPDM offers flexibility in energy performance choices. Black EPDM absorbs heat—beneficial in winter—while white EPDM reflects heat for cooling savings.
The material installs quickly using fully adhered, mechanically attached, or ballasted methods. Repairs are straightforward when damage occurs, and EPDM typically delivers 25-30 years of service.
EPDM’s competitive pricing makes it popular for residential flat roofs, small commercial buildings, and budget-conscious projects without sacrificing quality or longevity. It performs exceptionally well in coastal environments like Long Island.
PVC (Polyvinyl Chloride) Roofing
PVC represents the premium option in single-ply flat roofing membranes.
This material offers superior strength, chemical resistance, and fire ratings compared to other membrane types. PVC’s heat-welded seams and exceptional durability make it ideal for demanding applications including restaurant roofs exposed to grease, industrial buildings with chemical exposure, and high-traffic roofs.
PVC membranes resist punctures, tears, and microbial growth while maintaining flexibility throughout their service life. The material reflects solar heat effectively, reducing energy costs.
PVC’s superior strength means it can be installed in thinner gauges while maintaining performance, potentially reducing material costs despite higher per-square-foot pricing.
With proper installation and maintenance, PVC roofs regularly exceed 30-year lifespans. The material’s resistance to Long Island’s salt air and harsh weather makes it an excellent long-term investment for properties requiring maximum durability and minimal maintenance.
Modified Bitumen Roofing
Modified bitumen systems combine traditional built-up roofing reliability with modern polymer technology.
These multi-ply systems consist of asphalt modified with plastic or rubber polymers, reinforced with fiberglass or polyester, and surfaced with mineral granules or reflective coatings.
Modified bitumen excels in puncture resistance and handles foot traffic better than single-ply membranes. The multi-ply construction provides redundancy—if the top layer develops issues, underlying layers continue protecting the building.
This makes modified bitumen ideal for roofs requiring regular maintenance access or properties in areas with debris concerns.
Installation flexibility is another advantage. Modified bitumen can be torch-applied, cold-applied, or self-adhered depending on building requirements and fire code restrictions.
The systems perform well in temperature extremes and typically last 20-25 years. For Long Island properties wanting traditional roofing performance with modern improvements, modified bitumen offers an excellent balance.
Built-Up Roofing (BUR)
Built-up roofing represents the traditional flat roofing method with over a century of proven performance.
BUR systems consist of alternating layers of bitumen (asphalt or coal tar) and reinforcing fabrics, topped with an aggregate surface or reflective coating. The multiple layers create a thick, durable membrane.
While less common for new installations today, BUR systems offer excellent waterproofing, superior fire resistance with gravel surfacing, and proven longevity—many BUR roofs exceed 30 years. The aggregate surface protects the membrane from UV damage and physical impacts while providing excellent hail resistance.
BUR works well for Long Island properties with existing built-up systems, buildings requiring maximum fire protection, or owners preferring traditional roofing methods. The material handles thermal cycling and coastal weather effectively.
However, BUR installations are labor-intensive, heavier than modern membranes, and repairs can be more complex than single-ply systems.
County Roofing Systems helps Long Island property owners evaluate these options based on building type, budget, performance priorities, and long-term ownership plans. We provide honest assessments of which materials best suit your specific situation.
Flat Roof Installation Methods
For Long Island Homes and Properties
How your flat roof membrane attaches to the building directly impacts performance, longevity, and wind resistance.
County Roofing Systems masters all major installation methods and selects the appropriate technique based on your building structure, membrane type, local building codes, and performance requirements.
Fully Adhered Installation
Fully adhered systems bond the membrane directly to the substrate using specialized adhesives or hot asphalt.
This method creates a continuous bond across the entire roof surface, providing maximum wind uplift resistance—critical for Long Island’s coastal location where hurricanes and nor’easters bring extreme winds.
Fully adhered installation prevents membrane billowing in high winds, reduces noise from wind movement, and allows moisture in the substrate to escape through permeable adhesives. This method works with all membrane types and is often required by building codes in coastal wind zones.
It’s the preferred method for taller buildings and areas with severe weather exposure.
The technique requires careful substrate preparation—any irregularities telegraph through the membrane and can cause premature wear. Proper adhesive application is critical for performance. Our experienced crews ensure complete adhesion without voids that could allow water infiltration or wind uplift.
Mechanically Attached Installation
Mechanically attached systems use specialized fasteners and plates to secure the membrane to the roof deck.
Fasteners space according to engineered patterns that provide adequate wind resistance while minimizing penetrations. Seams receive additional reinforcement through heat welding, tape, or adhesive.
This method installs faster than fully adhered systems and costs less in materials and labor. Mechanical attachment accommodates slight substrate irregularities better than adhesion and allows faster installation in cooler weather when adhesives may not bond properly.
The technique works well for large commercial roofs where installation speed matters.
However, mechanically attached systems create multiple penetrations through the membrane—each requiring proper sealing to prevent leaks. Wind resistance depends on proper fastener spacing and plate installation. County Roofing Systems follows strict engineering specifications to ensure mechanically attached roofs meet Long Island’s coastal wind requirements while providing long-term watertight performance.
Ballasted Installation
Ballasted systems use heavy materials—typically river rock, pavers, or concrete blocks—to hold the membrane in place through weight rather than adhesives or fasteners.
The membrane attaches only at the perimeter, penetrations, and any inside corners. Ballast distributes weight evenly across the roof surface.
Ballasted installations offer several advantages: minimal roof penetrations reduce leak potential, installation completes quickly without adhesives or extensive fastening, the ballast protects the membrane from UV exposure and physical damage, and thermal mass from ballast reduces temperature fluctuations in the building.
This method requires adequate structural capacity to support ballast weight—typically 10-15 pounds per square foot. Building codes restrict ballasted systems in high-wind coastal areas due to ballast becoming projectiles during hurricanes.
Nassau and Suffolk County regulations often prohibit or severely restrict ballasted roofing in coastal wind zones.
Where permitted, ballasted systems work well for warehouses, storage facilities, and buildings with robust structural capacity. The method suits property owners wanting minimal roof penetrations and quick installation. However, maintenance and inspections require moving ballast to access the membrane.
Self-Adhered Installation
Self-adhered membranes feature factory-applied adhesive protected by a release liner.
Installers remove the liner and press the membrane onto the prepared substrate, creating a bond without additional adhesives, heat, or fasteners. This method has gained popularity for smaller flat roofs and residential applications.
Self-adhered systems install cleanly without torches, hot asphalt fumes, or adhesive odors—important for occupied buildings and residential properties. Installation proceeds safely in enclosed areas and sensitive environments.
The method eliminates concerns about improper adhesive application since bonding agents are factory-applied and quality-controlled.
Self-adhered membranes work excellently for Long Island residential flat roofs, small commercial buildings, additions, and roof sections over occupied spaces. The technique requires meticulous surface preparation—any dust, moisture, or irregularities prevent proper adhesion. Our crews prepare substrates carefully and install self-adhered membranes according to strict temperature and weather requirements.
Torch-Applied Installation
Torch-applied modified bitumen uses propane torches to melt the membrane’s underside, bonding it to the substrate or previous layer.
This method creates strong, immediate adhesion without separate adhesives. Multiple layers build up to create the final roof system.
Torch application provides excellent adhesion and allows installers to verify bond quality during installation. The method works well in cooler weather when cold adhesives might not perform properly.
Torch-applied systems are particularly popular for modified bitumen installations.
However, fire safety concerns restrict torch-applied methods near combustible materials, in certain building types, and where fire codes prohibit open flames.
Long Island building codes may restrict or prohibit torch application depending on building occupancy, construction type, and proximity to other structures. County Roofing Systems carefully evaluates fire safety requirements and obtains necessary permits when torch application is appropriate.
Cold-Applied Installation
Cold-applied systems use specialized adhesives, mastics, or primers that bond at ambient temperatures without heat, torches, or hot asphalt.
This method has become increasingly popular for safety, environmental, and practical reasons.
Cold-applied installation eliminates fire risks from torches and hot asphalt kettles, reduces fumes and odors affecting building occupants, allows work in areas where open flames are prohibited, and can proceed in temperature ranges unsuitable for other methods.
Modern cold-applied adhesives provide bonding strength comparable to heat-based methods.
This technique is ideal for Long Island occupied buildings, schools, healthcare facilities, residential properties, and additions where safety and minimal disruption are priorities. Cold application requires attention to temperature ranges, humidity levels, and proper adhesive coverage to ensure adequate bonding.
County Roofing Systems evaluates your building’s structure, local code requirements, membrane type, budget, and wind exposure to recommend the optimal installation method for your Long Island flat roof.
Our expertise across all installation techniques ensures your roof receives the method that delivers maximum performance and longevity.

Built-Up Roofing Systems: How to Protect Your Flat Roof
For Long Island Homes and Properties
Built-up roofing (BUR) systems have long been a cornerstone of the roofing industry, offering time-tested protection for flat roofs across Nassau and Suffolk counties.
Recognized for their durability and versatility, BUR systems are constructed from multiple layers of roofing felt and bitumen, finished with a protective layer of gravel or a reflective coating.
This multi-layered approach creates a robust waterproof barrier that shields the roof surface from UV rays, extreme temperatures, and the demanding weather conditions unique to Long Island.
For commercial, industrial, and residential buildings with flat roof types, built-up roofing remains a popular and practical choice.
The multiple layers of roofing material not only enhance the system’s resistance to punctures, tears, and heavy foot traffic but also provide excellent fire resistance and energy efficiency.
The top layer—whether gravel or a reflective coating—helps reduce heat absorption, lowering cooling costs during Long Island’s hot summers and extending the life of the roof deck.
One of the key advantages of built-up roofing is its adaptability. BUR systems can be installed using hot tar, cold adhesives, or even advanced methods that minimize disruption to building occupants.
This flexibility makes BUR suitable for a wide range of roofing needs, from new roof installations on industrial buildings to repair work on existing flat roofs in Deer Park and beyond.
When considering installation costs, built-up roofing systems often present a lower upfront investment compared to some newer flat roofing materials like modified bitumen roofing, thermoplastic polyolefin (TPO), or polyvinyl chloride (PVC) membranes.
However, the true value of BUR lies in its proven track record—decades of reliable performance, even under the stress of Long Island’s coastal climate.
With proper maintenance, including regular roof inspections and timely repairs of small holes or cracks, a built-up roof can last for decades, providing a secure and energy-efficient roofing system.
Maintenance requirements for BUR systems are straightforward but essential. Regular maintenance—such as clearing debris, checking for signs of wear, and ensuring the roof deck remains secure—helps prevent leaks and extends the lifespan of the roofing system.
A professional roofing contractor can provide expert guidance on maintenance schedules, perform thorough inspections, and address any issues before they escalate, ensuring your investment is protected year-round.
Compared to other flat roofing materials, built-up roofing offers a unique combination of low cost, durability, and versatility. While single ply roofing membranes like EPDM and TPO, or advanced options like modified bitumen and PVC, each have their strengths, BUR systems continue to be a reliable solution for property owners seeking a balance of performance and affordability.
Their ability to withstand heavy foot traffic and extreme temperatures makes them especially well-suited for industrial buildings and high-use commercial properties.
For property owners in Nassau and Suffolk counties, partnering with a professional roofing contractor experienced in built-up roofing BUR systems is crucial. County Roofing Systems brings decades of expertise to every project, from new installations to repair work and ongoing maintenance.
We help you navigate the different types of flat roofing materials, ensuring you choose the best option for your building’s needs and budget.
