Precision Flat & Low-Slope Roofs

    Discuss Your Project

    Flat Roof Installation, Repair & Inspections

     We design, install, and service low-slope roofs for Westchester County homes and commercial buildings. Our expertise includes single-ply membranes, SBS/APP modified bitumen, liquid-applied systems, and flat-seam copper, all installed with careful attention to proper drainage and lasting performance. 

    Flat and low-slope roofs demand a different approach.

     Small issues on flat roofs can develop into leaks quickly. We recommend periodic inspections especially after storms or rooftop work and provide detailed reports and maintenance plans to extend the life and performance of your roofing system. 

    Frequently Asked Questions

    Please reach us at info@groupthreeconstruction.com if you cannot find an answer to your question.

    Residential flat roof costs vary by material, complexity, and installation quality. EPDM is often the most cost-effective option, while premium systems like liquid-applied PMMA or flat-seam copper offer superior durability and design at a higher price. Roof size, existing conditions, insulation upgrades, and proper detailing also influence the final cost. 


    We start by scheduling an inspection and providing a detailed proposal. Once approved, we perform a “core test” to identify potential issues and reduce unforeseen costs. If necessary, we recommend insulation upgrades to improve roof pitch. At this stage, we review findings and options with you before sending the project to production for final scheduling. 


    Every roofing system has its strengths and limitations. With expertise across all options, we recommend the ideal system for your project. EPDM is a preferred choice for residential and commercial roofs in the Northeast, offering cost-effectiveness, ease of installation, and exceptional flexibility in cold weather, making it a durable, long-lasting solution. 


    Positive drainage is achieved by designing the roof slope so water flows naturally toward drains, scuppers, or gutters. We assess existing conditions and, if needed, recommend tapered insulation or mechanical pitch adjustments to ensure water is efficiently removed. Accepted industry standards call for any standing water to drain within 48 hours. 


    We are highly proficient in all low slope roofing solutions. After a careful assessment of site conditions, we will recommend the system or systems that best meets your needs and explain in detail why it is the most effective choice for your project.
