About Us
Honest Assessments, Quality Work - That's the Whole Model
There’s no shortage of roofing contractors on Long Island. What’s harder to find is one that gives you a straight answer about what your roof actually needs without padding the scope to increase the invoice. That’s the standard Excel Flat Roofing holds itself to on every job – whether it’s a residential flat roofing project or a large-scale commercial flat roofing installation across Suffolk County.
Our certified roofers are trained across every major flat roofing system – EPDM roofing, TPO roofing, PVC roofing, modified bitumen roofing, rubber roofing, and more. That range matters because not every building needs the same solution, and recommending the right flat roof repair or flat roof replacement for a specific property takes knowledge that only comes from real field experience.
Condo roofing services, multi-family roofing, property management roofing, HOA contracts – every project type is handled with the same thoroughness. As licensed flat roof contractors the size of the job has never determined the standard of the work.

Why Choose Us
What Keeps Property Owners Coming Back to Excel
We’ve earned our reputation as one of the best flat roofers in the area by combining technical expertise with straightforward communication and dependable results.
Emergency Response and Preventive Care
Roof problems don't wait for business hours- and neither do we. Whether it's a storm that tore through overnight or a leak that showed up out of nowhere, we respond fast and arrive ready to work. We also believe most emergency calls can be avoided with the right maintenance approach. Regular inspections, catching drainage issues early, addressing small membrane problems before they spread- that's the kind of attention that keeps a roof performing for years instead of falling apart prematurely. Every job we finish is backed by a warranty, and if anything isn't right after we leave, we come back and sort it out. No runaround.
Complete Flat Roof System Expertise
Not every building is the same, and not every roof problem has the same answer. Some properties need a lightweight single-ply system. Others need something tougher- a built-up or modified bitumen setup that handles heavy foot traffic or rooftop equipment. Some jobs call for improved drainage or ventilation before a new membrane even makes sense. Our crew understands the full picture, which means we can look at your roof, understand what it actually needs, and recommend a solution that fits- not just whatever's easiest for us to install.
Proven Track Record Across the Region
Experience on paper means a lot less than experience in the field. We've worked on properties all across Long Island- from smaller residential jobs in neighborhoods like Holbrook and Medford to larger commercial projects in Huntington, Hauppauge, and Ronkonkoma. That kind of range builds something you can't fake: a real understanding of how different buildings age, how local weather affects different roof systems, and what property owners here actually need. When you call us, you're getting a crew that knows this area because they've worked in it.

Roofing Guide
Practical Roofing Knowledge Built Around How Long Island Properties Work
Covering materials, drainage, climate damage, maintenance, and system comparisons in plain language that actually helps you make better decisions about your building.
General Flat Roofing
Understanding how flat roofing systems work and how they hold up over time, makes every maintenance and replacement decision easier and less expensive.
General Info
Never dealt with a flat roof before? This is the right place to start. Honest, straightforward answers to the questions most property owners have at the beginning.
Structures & Extensions
Building shape and layout affect everything from system selection to how water moves off the roof. Here's what that means for your specific property.
Technical & Structural
Deck conditions, load capacity, and substrate compatibility matter more than most property owners realize, explained here without unnecessary technical complexity.
Materials & Systems
EPDM, TPO, PVC, modified bitumen and built-up roofing, each system has real trade-offs worth understanding before committing to an installation or replacement.
Materials & Comparisons
Cost, durability, maintenance demands, and climate performance compared side by side so you can evaluate options based on facts, not a contractor's preference.
Skylights & Windows
Cutting into a flat roof for a skylight changes the entire waterproofing dynamic. Learn what proper installation actually requires before the work begins.
Ventilation & Insulation
Inadequate ventilation and poor insulation quietly shorten a roof's lifespan while driving energy bills up. Find out what your system genuinely needs.
Drainage & Slope
Ponding water causes more flat roof failures than almost anything else. Proper drainage design and slope planning are what prevent it from becoming your problem.
Maintenance & Lifespan
Knowing what to inspect, what to schedule, and what to never ignore is the difference between a roof that lasts and one that fails ahead of schedule.
Problems & Climate
Freeze-thaw cycles, heavy snow loads, storm damage, and coastal moisture. Long Island's climate creates specific roofing challenges. This section covers what to watch for and when to act.

Frequently Asked Questions
Straightforward Answers to the Questions We Hear Most
What flat roof material do you recommend for Long Island properties?
TPO roofing, EPDM roofing, and PVC roofing are our most common recommendations – all three handle temperature fluctuation and ponding water well. Modified bitumen roofing and built-up roofing are better suited for commercial buildings with heavy rooftop equipment. Rubber roofing is a practical, budget-friendly option for residential applications, and torch down roofing holds up well in high-traffic areas. We assess the building first and recommend based on what actually fits.
How do I know whether I need a repair or a full replacement?
Isolated leaks or limited membrane damage usually point to flat roof repair being the right move. Multiple recurring leaks, widespread cracking or bubbling, interior water damage, or a system older than 20 years typically means flat roof replacement is the better long-term investment. Our roof inspection services give you a clear picture – and an honest recommendation either way.
Are your emergency services available nights and weekends?
Yes. Our 24-hour roof repair coverage runs every day – nights, weekends, and holidays included. Active leaks, sudden storm damage, urgent commercial roof repair that can’t sit until Monday – call us and we’ll get someone out as fast as the situation demands.
Do you work directly with property management companies and HOAs?
Regularly. Property management roofing and HOA roofing contractor work require a different level of coordination than a standard job – scheduling around tenants, detailed documentation, communication with multiple decision-makers. We handle all of it. Routine flat roof maintenance or a full apartment building roofing project – the process stays clear and organized throughout.
What does your warranty actually cover?
Material warranties on TPO roofing, EPDM roofing, and PVC roofing systems typically range from 10 to 30 years depending on the manufacturer. Our workmanship warranty covers the installation itself – including roof membrane installation and all labor involved. Coverage details are explained clearly before any work begins. Guaranteed roof repair means if something isn’t right after we leave, we come back and make it right.
