Our Flat Roofing Process — Built for Long Island Properties

Every flat roofing project on Long Island follows a proven process designed to ensure durability, efficiency, and long-term performance.
We begin by discussing your building’s needs, current roof performance, and long-term goals. During the site evaluation, we inspect the existing flat roofing system, assess drainage patterns, check insulation performance, and evaluate the structural substrate to determine the best approach for installation or replacement.
Based on the size of your roof, building use, energy efficiency goals, and budget, we recommend the most appropriate flat roofing system. Options may include TPO, EPDM, or modified bitumen, each selected for durability, weather resistance, and performance suited to your specific property.
You receive a comprehensive written proposal outlining the full scope of work, system specifications, materials, insulation details, projected timeline, warranty coverage, and total investment. We review the proposal with you to ensure clarity and answer any questions before moving forward.
If replacement is required, we carefully remove the existing roofing materials and inspect the decking underneath. Any damaged sections are repaired or replaced to create a stable base. We then prepare the surface to ensure proper adhesion, sealing, and long-term system performance.
Our team installs your new flat roofing system using manufacturer-approved techniques and industry best practices. Special attention is given to seams, flashing, penetrations, and drainage components to ensure watertight protection, energy efficiency, and reliable performance in all weather conditions.
After installation, we conduct a detailed quality inspection to verify proper sealing, drainage flow, and system integrity. The site is thoroughly cleaned, debris is removed, and we review the completed project with you to confirm satisfaction and provide warranty documentation.

Frequently Asked Questions — Flat Roofing on Long Island

Thinking about flat roof repair or replacement? Here are answers to common questions about flat roofing on Long Island that property owners frequently ask
The cost of flat roof repair on Long Island typically ranges from $400 to $1,500 depending on the size and type of damage. A full flat roof replacement can range from $5,000 to $15,000 or more depending on the roofing system selected, the square footage, and the condition of the existing decking. We provide free, detailed quotes so you know exactly what you’re getting before any work begins.
The lifespan of a flat roof depends on the system installed. EPDM and TPO systems typically last 20–30 years when properly installed and maintained. Modified bitumen roofs average 15–20 years. Regular flat roof repair and annual inspections can significantly extend the life of any flat roofing system.
Long Island experiences cold winters, hot summers, coastal winds, and heavy rain — all of which place unique demands on a flat roof. TPO and EPDM are both excellent choices because of their flexibility, weather resistance, and energy efficiency. As your flat roofing contractor Long Island, we’ll help you select the right system for your specific building and climate exposure.
Yes. Aaron Roofing Corp handles commercial flat roofing projects of all sizes across Long Island. From small retail buildings and multi-family units to larger commercial properties, our team has the experience, equipment, and licensing to deliver professional-grade results on every commercial flat roofing job.
If the damage is isolated — a small membrane tear, a failed seam, or minor flashing damage — a targeted flat roof repair is often the most cost-effective solution. If the membrane has widespread deterioration, the insulation is saturated, or the roof is approaching the end of its lifespan, a full flat roof replacement will provide better long-term value. Our flat roofing contractor team will give you an honest recommendation after a thorough inspection.
