Our Flat Roofing Long Island NY Experts.

At Mayancelas Jr. Roofing LLC, we provide professional flat roofing services throughout Long Island, installing and repairing EPDM, modified bitumen, and TPO systems for commercial and residential properties of all sizes. Our team uses certified materials designed to handle Long Island weather.

Every flat roof installation is completed with precision, proper drainage, and thorough waterproofing to provide reliable, long-lasting protection. We also offer free inspections and detailed written estimates for every project.

The Benefits of Flat Roofing

Flat roofing delivers long-term protection at a lower cost per square foot. Here is what you gain.

Strong Waterproofing to Prevent Leaks and Pooling

Modern flat roofing systems use membranes and proper drainage to prevent water pooling and leaks. EPDM and modified bitumen create a continuous waterproof barrier that holds up through Long Island rain, snow, and ice seasons.

Cost-Effective Flat Option

Flat roofing costs less per square foot than pitched systems, making it ideal for commercial buildings and large residential additions as well.

Long Lifespan with Low Ongoing Maintenance Needs.

EPDM membranes last 20 to 30 years with minimal upkeep. Modified bitumen is equally durable. Flat roofs need less maintenance than pitched systems once installed.

Easy Rooftop Access for HVAC and Equipment

Flat roofs provide safe, accessible space for HVAC units, solar panels, and rooftop equipment. Crews work efficiently without the hazards and staging costs of steep slopes.

How It Works

Our 4-Step Flat Roofing Process

From free inspection to final drainage check: clean, efficient, waterproofed flat roofing on every project.

Free Roof Inspection

Our inspector checks your flat roof condition and drainage, documents all issues, and explains what needs to be done. Free, no obligation.

System Selection & Written Estimate

We walk you through EPDM, modified bitumen, or TPO options with a written estimate covering materials, scope, and timeline. No hidden costs.

Flat Roof Membrane Installed

Our crew installs your system using certified materials, ensuring correct drainage, sealed edges, and full membrane coverage. Clean, done right.

Final Inspection & Cleanup

We do a complete walkthrough, verify drainage and waterproofing, remove all debris, and hand you your warranty. Your property is left clean and fully protected.
