Green Vegetation Installation

Vegetative or “Green” Roofing is when plants are installed over the weatherproofing layer on a commercial roof.
This could be in conjunction with pathways and areas for people, or it could just be an environmental/sustainable push from a company. Depending on the structure of the building, you can install grass, bushes, flowers or trees.

Why Choose vegetative Roofing?
Expand Usable Space – By adding more places for people to hang out, eat lunch or hold meetings, you are capitalizing on a square footage that your building offers.
Upgrade Facility Aesthetics – Having a well-maintained space upgrades the perceived value of the facility. A rooftop patio or garden can be an offering that tenants are willing to pay for.
Employee Wellness/Satisfaction – The more dedicated relaxation areas you can provide to your employees, the higher employee morale will be. Environmentally Friendly and Sustainable – Not only can vegetative green roofs save energy costs associated with heating and cooling the facility, therefore reducing your building’s carbon footprint.

Vegetative Roofing Installation
If a facility is able to have a vegetative roof installed, it means that the substrate is strong and probably made of concrete.
If not, the substrate needs to be reinforced to handle the weight and traffic of the green roof.
A Green Roof installation starts with a waterproof membrane. This membrane can be a Rubberized Asphalt, Modified Bitumen, Spray Polyurethane, Single-Ply Membrane, or Polyvinyl Chloride (PVC).

Tray Systems
A tray system is a rather easy way to bring vegetation to your facility roof. The plants, or other vegetation, are planted in lightweight trays that are brought up to the roof. These tray systems can be interconnecting and specialized edges, along with growing plants, can conceal the trays to create a seamless look.
Advantages of tray systems are maximum stormwater management with trays designed to capture waterfall, easy installation, and plants can be grown before installation.

Layered Systems
Layered systems are installed directly onto the roof surface. There are two types of layered vegetative systems: Extensive Systems are more modular, and Intensive Systems are deeper. When the vegetation is not limited to trays, more layers need to be installed to protect the facility from water damage:
Water Retention Layer – Properly holds water for the plants and other vegetation, it’s important that the water is available for the plants but doesn’t sit on the facility structure where it can cause water damage.
Drainage Layer – Helps the water drain properly and prevent water from sitting on the roof and causing damage.
Advantages of tray systems are lighter option when including trays, and more choices with installation shape.
