Flat Roof Repair & Installation
Expert flat and low-slope roof systems using TPO, EPDM, and modified bitumen for homes with flat or nearly flat roof sections.
About Flat Roof Repair & Installation
Flat and low-slope roofs present unique challenges that standard roofing contractors often handle poorly. Without the natural drainage slope of a pitched roof, flat roofing systems must rely entirely on membrane integrity and proper drainage design to keep water out. Edison Roofing Contractor specializes in residential flat roof repair and installation throughout Middlesex County, using commercial-grade membrane systems that deliver reliable, long-lasting performance on the flat sections of your home. Many homes in Middlesex County have flat roof sections over additions, garages, porches, sunrooms, and row house configurations. These areas are prone to ponding water, membrane shrinkage, seam separation, and accelerated deterioration from UV exposure. Our flat roofing solutions address these challenges with membrane systems specifically engineered for low-slope applications: TPO for energy efficiency and weldable seam strength, EPDM rubber for flexibility and impact resistance, and modified bitumen for superior puncture resistance and walkability. We evaluate your specific situation to recommend the membrane type, drainage approach, and insulation strategy that will deliver the best long-term performance. Every flat roof installation includes proper slope creation to eliminate ponding, fully adhered or mechanically fastened membrane attachment, heat-welded or chemically bonded seams, and custom-fabricated edge details and flashing. Our repair services address the common flat roof failures including ponding water damage, blister formation, seam separation, membrane punctures, and flashing failures at walls and parapets.
Our Flat Roof Repair & Installation Process
Flat Roof Assessment
We evaluate your flat roof area including drainage patterns, existing membrane condition, insulation adequacy, and structural capacity to determine the best approach.
System Design & Specification
We design the complete flat roofing system including membrane type, attachment method, insulation thickness, drainage improvements, and edge detail configurations.
Substrate Preparation
The existing roof is removed, decking is repaired, and tapered insulation is installed to create proper drainage slope toward scuppers or interior drains.
Membrane Installation
The selected membrane system is installed with heat-welded seams, fully adhered field attachment, and custom-formed flashings at all transitions and penetrations.
Water Test & Final Inspection
We flood-test the completed roof to verify watertight integrity at all seams, flashings, and penetrations before signing off on the project.

Flat Roof Repair & Installation FAQ
What is the best material for a flat roof on a home?
The best flat roof material depends on your specific priorities. TPO membrane is the most popular choice for residential flat roofs due to its excellent UV resistance, energy-efficient white surface, heat-weldable seams, and competitive pricing. EPDM rubber membrane is extremely durable and flexible, making it ideal for roofs subject to foot traffic or in areas with extreme temperature swings. Modified bitumen offers the best puncture resistance and is self-healing in warm temperatures. For most residential flat roof applications in Middlesex County, we recommend TPO for its combination of performance, energy efficiency, and value.

Why does my flat roof keep leaking?
Chronic flat roof leaks typically result from one or more of three root causes: ponding water from inadequate drainage slope, deteriorated seams where membrane sections join, or failed flashings where the roof meets walls, parapets, or penetrations. Many flat roofs were installed without adequate slope, allowing water to sit in pools that accelerate membrane deterioration and eventually break through. Others have seams that were improperly bonded or have opened over time from thermal cycling. The solution is not just patching the leak point but addressing the underlying cause, whether that means adding tapered insulation for drainage, re-welding seams, or replacing failed flashing details. Edison Roofing Contractor diagnoses and solves the root cause, not just the symptom.
How long does a flat roof last?
A properly installed flat roof membrane system lasts 20 to 30 years depending on the material chosen, installation quality, and maintenance frequency. TPO and EPDM membranes typically carry manufacturer warranties of 15 to 25 years, with actual field performance often exceeding warranty terms when properly maintained. The keys to flat roof longevity are proper drainage slope to eliminate ponding, fully welded or bonded seams, correct attachment method for your specific conditions, and periodic maintenance inspections to catch minor issues before they become failures. Edison Roofing Contractor provides annual maintenance inspections for all flat roof installations to ensure maximum lifespan.
