Systems We Install

Commercial Roofing Systems

Commercial roofs are not residential. Greenway specializes in low-slope and flat membrane systems engineered for the demands of commercial buildings.

TPO Roofing
Thermoplastic Polyolefin single-ply membrane systems. Energy-efficient white reflective surface, heat-welded seams, and excellent puncture resistance. Industry-leading warranties.
EPDM Rubber Roofing
Durable synthetic rubber membrane proven to last 25-30+ years. Cost-effective for large commercial roofs with minimal maintenance requirements.
Modified Bitumen
Multi-ply asphalt-based system ideal for low-slope and flat commercial roofs. Excellent waterproofing with proven performance in Mid-Atlantic climate.
Built-Up Roofing (BUR)
Multiple layers of asphalt and reinforcing fabrics for maximum durability. Time-tested system for commercial buildings demanding the highest performance.
Metal Roofing
Standing seam metal systems for warehouses, retail, and industrial properties. 40-50+ year lifespan with minimal maintenance.
Roof Coatings
Silicone, acrylic, and elastomeric coatings to extend the life of your existing roof by 10-15 years at a fraction of replacement cost.
Commercial Roof Inspections

Catch Problems Before They Cost You

A small leak today is a tenant disruption, insurance claim, and capital expense tomorrow. Greenway's commercial inspection identifies issues early — and prevents them from escalating into costly repairs or full system failure.
