Residential Flat Roofing Contractor
While flat roofs are more commonly seen atop commercial buildings, many Long Island homeowners are choosing residential flat roofing for their new homes.
Although this roof type is less common in residential settings, it is becoming increasingly popular due to its modern aesthetic and versatility.
Flat roofs give homes a sporty modern look. They offer the chance to create roof decks, rooftop gardens, and patios. You also get more top floor space with a flat roof than with a conventional sloped roof.
But Long Island flat roofs also come with special challenges. Heavy snowfall and high winds pose serious environmental challenges.
You need a Long Island roofing contractor with experience in residential and commercial flat roof installation, and a strong reputation in the roofing industry. And that means you need County Roofing Systems.

Understanding Low Slope Roofing Systems
First, flat roofs are not precisely “flat” but are instead built with a gentle slope.
Most flat roofs require a minimum slope (typically 1/4 inch per foot) to prevent ponding and ensure proper drainage.
Low slope roofing systems typically feature a pitch of 1 inch per foot or less, which facilitates the runoff of rain and snow melt. Without that pitch, water will pool up on your roof and, over time, cause leaks and structural damage.
Modern low slope roofing systems are engineered specifically for these minimal-pitch applications, providing reliable waterproofing that traditional steep-slope materials cannot deliver.
The roof deck serves as the structural base that supports the roofing materials and insulation, and its positioning is crucial for proper installation and performance.
These specialized systems account for the unique drainage challenges and weather exposure that most flat roofs experience.
Types of Residential Flat Roofing Materials
EPDM Roofing (Rubber Membrane)
EPDM roofing, which stands for ethylene propylene diene monomer, is one of the most popular choices for residential flat roofing applications.
This synthetic rubber membrane is a type of single ply membrane made from ethylene propylene diene, known for its durability and weather resistance. EPDM roofing typically comes in large sheets that minimize seams, reducing potential leak points.
The material’s flexibility allows it to expand and contract with temperature changes without cracking or splitting.
EPDM roofing can last 20-30 years with proper maintenance, making it an excellent value for homeowners seeking reliable flat roof replacement solutions.
TPO Roofing Membrane
TPO (thermoplastic polyolefin) roofing membrane is a type of single-ply membrane that has become increasingly popular for both commercial and residential flat roofing applications.
TPO membranes are a blend of rubber and plastic polymers, specifically polypropylene and ethylene-propylene rubber, making them highly energy-efficient and resistant to UV rays.
This popular roofing material is also known for its UV reflectivity, resistance to mold and pollutants, and overall sustainability benefits.
TPO roofing membrane is heat-welded at the seams, creating watertight bonds that are stronger than adhesive-based systems.
The material resists mold growth, punctures, and tears, providing long-lasting protection for your home. Many homeowners choose TPO roofing membrane for its combination of durability, installation flexibility, and energy-saving benefits.
Modified Bitumen Roofing
Modified bitumen roofing, also known as a mod bit roofing system or mod bit roof, is a sturdy yet flexible asphalt membrane mixed with polymerized rubber or plastic and fiberglass reinforcement.
Modified bitumen roofing evolved from built-up roofing systems, which have been used on low-slope roofs for over a century.
A mod bit system can be installed with or without heat using self-adhesive components, torch-applied, or cold-adhesive methods.
The installation process can produce heavy fumes, so proper safety equipment is required. Mod bit roofing systems are commonly sold in rolls that are adhered directly to roofing substrates.
This multi-layer protection system typically consists of two or more layers, providing excellent waterproofing protection and enhanced durability, especially in multi-ply applications.
The material’s reinforced construction offers excellent resistance to foot traffic, making it ideal for rooftop decks or roofs requiring regular maintenance access.
The average life expectancy of a mod bit roof is about 20 years, depending on maintenance and installation quality, which is comparable to or slightly less than some other materials used in residential flat roofing.
Mod bit is ideal for use on flat and low-slope roofs in commercial, industrial, and residential applications, offering good value and reliable performance.
Built-Up Roofing (BUR)
Built-up roofing, also known as a built up roof or BUR system, is one of the oldest roofing systems and has protected flat roofs for over a century.
BUR systems are constructed using alternating layers of asphalt-impregnated felt and bitumen, creating a durable and weather-resistant surface.
This system uses multiple plies of asphalt-impregnated felt bedded in bitumen, topped with gravel or stone to protect against UV damage and provide fire resistance.
While newer materials have gained popularity, built-up roofing remains a reliable choice for residential flat roofing, particularly for homeowners seeking traditional proven performance.

Benefits of Residential Flat Roofing
Why Choose a Flat Roof?
Additional Usable Space
Flat roofs create opportunities for rooftop living areas, gardens, solar panel installations, and HVAC equipment placement. This additional functional space is especially valuable on smaller urban lots where every square foot matters.
Modern Aesthetic Appeal
Contemporary home designs often incorporate flat roofing elements to achieve clean, minimalist architectural lines. The modern look complements urban and suburban contemporary home styles.
Easier Access and Maintenance
The relatively level surface of low slope roofing systems makes inspection, maintenance, and repairs safer and more straightforward than steep-slope roofs. This accessibility can reduce long-term maintenance costs.
To ensure longevity and optimal performance, it is important to follow specific maintenance routines tailored to residential flat roofing. Regularly clearing debris, checking for ponding water, and inspecting seams are key maintenance tips that help prevent issues and extend the roof’s lifespan.
Cost-Effective Installation
Flat roof replacement typically requires less material and labor than complex pitched roofs, potentially reducing installation costs. The simpler geometry means faster installation in many cases.
Installation Considerations for Flat Roofs
Proper Drainage Design
Effective water management is critical for residential flat roofing success.
A well-designed drainage system, which can include scuppers or drains, is essential to direct water off the roof and prevent water accumulation.
Roofing professionals must carefully plan drainage routes, ensuring water flows efficiently to scuppers, drains, or gutters.
Standing or pooling water on a flat roof is typically a sign that the roof’s slope needs to be adjusted or that the drainage system is malfunctioning. Standing water accelerates membrane deterioration and can lead to leaks.
Membrane Installation Techniques
For further protection, flat roofers use single-ply membranes like EPDM roofing or TPO roofing membrane.
These membranes produce strong, leak-resistant seals on your roof. They also expand and contract with temperature changes without cracking.
Roofers must lay these membranes carefully to prevent water damage. Professional installation techniques—whether mechanically fastened, fully adhered, or ballasted—ensure long-term performance and weather resistance.
Flashing and Penetrations
Roofers must flash all skylights, vents, and roof borders properly. Flashing, and the points where different sheets of roofing membranes meet, are often the source of leaks. That is why hiring a company with flat roofing expertise is so important.
All roof penetrations require careful waterproofing detail work. County Roofing Systems has the experience to handle these critical junctions properly, preventing the most common sources of flat roof leaks.
Insulation Requirements
Proper insulation beneath low slope roofing systems improves energy efficiency and prevents condensation issues. Modern flat roof systems typically incorporate rigid foam insulation boards that provide excellent R-value while maintaining proper drainage slopes.

Flat Roof Maintenance
Taking Care of Your Flat Roof
Regular maintenance extends the life of residential flat roofing systems significantly. We recommend bi-annual inspections—once in spring after winter weather, and again in fall before winter arrives.
Debris Removal
Keep your flat roof clear of leaves, branches, and other debris that can block drains and retain moisture. Regular cleaning prevents drainage issues and reduces the risk of membrane damage.
Inspection of Seams and Flashing
Check seams, flashing, and penetrations regularly for signs of separation or damage. Early detection of minor issues prevents them from becoming major problems requiring extensive repairs.
Drain Maintenance
Ensure roof drains and scuppers remain clear and functional. Clogged drains lead to ponding water, which significantly shortens roof membrane lifespan.
Professional Inspections
While homeowners can perform basic visual checks, professional inspections identify potential issues that untrained eyes might miss. County Roofing Systems offers comprehensive flat roof inspections that assess membrane condition, drainage effectiveness, and overall system performance.
Flat Roof Layovers and Tear Offs
When Layovers Make Sense
Sometimes we can add a new base and a membrane in a layover. This is a cost effective roofing solution for a roof which is otherwise sound, and can add years to your current flat roof’s life.
Layover applications work well when the existing roof surface is structurally sound, properly drained, and free from excessive moisture. This approach saves on disposal costs and installation time while providing a fresh protective layer.
When Complete Flat Roof Replacement Is Necessary
But sooner or later every flat roof needs a complete replacement. Each additional layer adds weight, and in time that weight can overburden your roofing supports.
You will also need a tear off if your insulation is wet or if the roof decking is warped or rotted.
When we do a tear off we remove all the previous roofing materials. We then replace any damaged plywood or insulation.
Then we install a brand new flat roof to your specifications using your choice of EPDM roofing, TPO roofing membrane, modified bitumen roofing, or other appropriate low slope roofing systems.
Signs You Need Flat Roof Replacement
Visible Membrane Damage
Cracks, tears, blistering, or significant wear on the roof membrane indicate the material has reached the end of its service life. Once membrane integrity is compromised, repairs become less effective than full replacement.
Persistent Leaks
If you’re experiencing recurring leaks despite repairs, the underlying roof system may be failing. Multiple leak points often indicate systemic problems that warrant complete flat roof replacement.
Interior Water Damage
Water stains on ceilings, mold growth, or musty odors suggest moisture has penetrated your roofing system. These signs indicate serious problems requiring immediate professional evaluation.
Age of Roof
If your flat roof is approaching or has exceeded its expected lifespan (15-30 years depending on material), proactive replacement prevents emergency situations and allows for planned budgeting.
