Green Roofing
Sustainable green roof systems that reduce energy costs, manage stormwater, and enhance your building value.
About Green Roofing
Green roofing transforms underutilized commercial roof space into living, working ecosystems that deliver measurable environmental, economic, and aesthetic benefits. Edison Roofing Contractor designs and installs green roof systems for commercial buildings across Middlesex County, from lightweight extensive systems with low-maintenance sedum plantings to intensive rooftop gardens that create usable outdoor space for tenants and employees. A green roof system consists of a waterproofing membrane, root barrier, drainage layer, growing medium, and carefully selected vegetation that together create a living roof surface. This layered system absorbs stormwater, reducing runoff by fifty to ninety percent and potentially lowering your stormwater management fees. The vegetation and growing medium provide natural insulation that reduces heating costs in winter and cooling costs in summer, with documented energy savings of ten to thirty percent for top-floor spaces. Green roofs also extend the life of the underlying waterproofing membrane by protecting it from UV radiation and temperature extremes, potentially doubling the membrane service life. New Jersey municipalities are increasingly offering incentives for green roof installations including stormwater fee reductions, tax credits, and expedited permitting. For building owners looking to differentiate their properties, attract environmentally conscious tenants, and achieve sustainability certifications like LEED, a green roof provides visible, measurable impact. Let us show you how a green roof can transform your building from an environmental liability into a sustainability asset.
Our Green Roofing Process
Structural Assessment and Design
We evaluate your building structural capacity to support the additional weight of a green roof system and design the appropriate system type, depth, and plant palette for your building.
Waterproofing and Root Barrier Installation
A premium waterproofing membrane with root barrier protection is installed to protect your building structure from moisture and root penetration for the life of the green roof.
Drainage and Growing Medium Layers
Drainage mats, filter fabric, and engineered growing medium are installed in layers designed to retain optimal moisture for plant health while draining excess water efficiently.
Vegetation Installation
Pre-grown vegetation mats or individual plantings are installed based on the system design, using species selected for New Jersey climate, drought tolerance, and low maintenance.
Establishment Care and Handoff
We provide initial watering and care during the plant establishment period, then train your maintenance team and provide ongoing care guidelines for long-term success.

Green Roofing FAQ
How much weight does a green roof add to my building?
Extensive green roof systems with sedum plantings typically add fifteen to twenty-five pounds per square foot when fully saturated, which is comparable to the weight of a gravel-ballasted single-ply roof system. Intensive green roof gardens with deeper soil and larger plants can add fifty to one hundred fifty pounds per square foot. Most commercial buildings constructed in the last forty years can support extensive green roof systems without structural modification. Older buildings or those designed for lightweight roof systems may need structural reinforcement. We perform a structural assessment as the first step of every green roof project to ensure your building can safely support the system. Contact us for a structural evaluation.
What maintenance does a green roof require?
Extensive sedum green roofs require minimal maintenance, typically two to four visits per year for weed removal, drain clearing, fertilization, and inspection of the vegetation health. These roofs are designed to be self-sustaining once established, surviving on natural rainfall without regular irrigation in normal New Jersey weather patterns. Intensive green roof gardens require maintenance similar to ground-level landscaping, including regular watering, pruning, fertilization, and seasonal planting. We offer green roof maintenance programs for both system types so your investment continues performing at its best. Ask about our annual maintenance packages when you request your estimate.
Are there incentives for installing a green roof in New Jersey?
Yes. Several New Jersey municipalities offer incentives for green roof installations including stormwater management fee reductions, tax abatements, and expedited building permits. The NJ Department of Environmental Protection supports green infrastructure through various grant programs. Green roofs also contribute points toward LEED certification, which can qualify your building for additional tax incentives and attract premium tenants willing to pay higher rents for sustainable buildings. The combination of energy savings, extended roof life, stormwater fee reductions, and increased property value often delivers a positive return on investment within seven to twelve years. We help you identify applicable incentives in your municipality. Schedule a consultation to explore your options.
