First, we inspect your existing roof thoroughly, checking drainage, membrane condition, and potential problem areas. No guesswork—we use advanced leak detection equipment to find issues you can’t see.
Next, we explain what we found in plain English and give you options that make sense for your property and budget. We don’t oversell or push unnecessary work because our reputation depends on honest recommendations.
During installation, we protect your landscaping and property, work efficiently to minimize disruption, and clean up completely each day. You’ll know exactly what’s happening and when to expect completion.

TPO roofing offers excellent durability and energy efficiency, reflecting heat to keep your home cooler and energy costs lower. It handles Upper Brookville’s weather extremes well and comes with strong manufacturer warranties.
EPDM rubber roofing provides reliable waterproofing and flexibility, adapting to temperature changes without cracking. It’s particularly good for properties with complex roof shapes or multiple penetrations.
Modified bitumen systems work well for high-traffic roofs and offer excellent puncture resistance. They’re especially suitable for properties where roof access is frequent or where maximum durability is priority.
We help you choose based on your specific building requirements, local weather patterns, and long-term goals. Each material has advantages, and we match the right solution to your particular situation rather than pushing one-size-fits-all approaches.
A properly installed flat roof in Upper Brookville typically lasts 15-30 years, depending on the material and maintenance. TPO systems often reach 20-30 years with proper care, while EPDM can last 20-25 years.
The key is professional installation and regular maintenance. Long Island’s weather—from humid summers to harsh winters—puts extra stress on roofing materials, so quality installation makes a huge difference in longevity.
We’ve seen well-maintained flat roofs exceed their expected lifespan, while poorly installed ones fail in just a few years. That’s why choosing experienced contractors familiar with local conditions matters so much.
Most flat roof leaks in Upper Brookville come from improperly installed or deteriorated flashing around penetrations like vents, HVAC units, and chimneys. These areas are where the roof membrane meets vertical surfaces, creating potential weak points.
Standing water is another major culprit. When drainage systems get clogged with leaves or debris, water pools on the roof surface. If water sits for more than 48 hours, it can penetrate the membrane and cause permanent damage.
Membrane shrinkage from UV exposure and temperature cycling also creates problems over time. The material gradually pulls away from edges and penetrations, opening gaps where water can enter. Regular inspections catch these issues before they become major leaks.
Sometimes, yes—but only if the existing roof structure is sound and local codes permit it. We thoroughly inspect the current roof, decking, and structural support before recommending a roof-over installation.
Installing over existing roofing can save money by eliminating tear-off costs, but it’s not always the right choice. If there’s existing water damage, structural issues, or too many layers already, complete removal is safer and more cost-effective long-term.
We evaluate each situation individually and give you honest recommendations. If a roof-over works for your property, we’ll explain the process and any limitations. If full replacement is better, we’ll explain why and help you understand the long-term benefits.
Proper drainage is critical for flat roof performance, especially in Upper Brookville where we get heavy rains and snow. We start by evaluating your current drainage system—drains, scuppers, and roof slope—to identify problem areas.
For minor pooling issues, we can install additional drains or improve existing ones. More significant problems might require tapered insulation systems to create proper slope toward drainage points, ensuring water flows off the roof efficiently.
We also install high-quality drain systems with proper flashing and overflow provisions. This prevents backups during heavy storms and protects against the standing water that destroys flat roof membranes. Good drainage design is just as important as membrane quality for long-term roof performance.
Flat roofs need regular inspections and basic maintenance to reach their full lifespan. We recommend professional inspections twice yearly—spring and fall—plus after major storms to check for damage.
Basic maintenance includes keeping drains and gutters clear of debris, checking membrane condition around penetrations, and addressing small issues before they become major problems. Most maintenance tasks are simple but require knowing what to look for.
We provide maintenance guidance after installation and can set up regular service schedules if you prefer professional handling. Preventive maintenance costs far less than emergency repairs and helps your roof reach its expected lifespan. Many warranty claims result from poor maintenance, so staying on top of it protects your investment.
Flat roof replacement costs vary significantly based on material choice, roof complexity, and current condition. Basic EPDM systems might run $8-12 per square foot installed, while premium TPO systems range $10-16 per square foot.
Factors affecting cost include roof size, number of penetrations, accessibility, existing roof removal requirements, and any structural repairs needed. Complex rooflines with multiple levels or extensive HVAC equipment cost more than simple rectangular roofs.
We provide detailed written estimates that break down all costs—materials, labor, permits, and cleanup. No surprises or hidden fees. We also explain different material options and help you understand the long-term value of each choice, so you can make informed decisions based on your specific needs and budget.
