GREEN ROOF SYSTEMS

About Green Roof Design & Construction:

Apex Green Roofs builds vegetated roof systems that are designed to meet the precise needs of each project.  Each roof surface is its own microclimate and has specific design parameters.  It goes without saying that you cannot apply blanket solutions to a green roof.  Apex Green Roofs is not married to any particular product.  This allows us the flexibility to deliver the best product to you, and for your roof’s specific needs.  Thoughtful design and care go into each green roof project we construct.

There are several types of vegetated roof systems we can install to meet your project goals and desires.

STONECROP™
EXTENSIVE GREEN ROOF SYSTEM

The Stonecrop™ extensive system is the thinnest system supporting only the toughest plant species.  These systems range in depth from 3" - 6" and do not have irrigation.  Most herbaceous material can't survive and only succulents, like sedums, seem to thrive.  Your roof will need to support a minimum of 20 pounds per square foot for this type of system.

STRATA™
SEMI-INTENSIVE GREEN ROOF SYSTEM

The Strata™ vegetated roof system offers a much greater palette of plants from which to work with. Semi-intensive systems are anything ranging from 6" - 9" in depth. They have two layers of media; a drainage media (eliminating the need for a synthetic drainage layer) and growth media. Both support the more extensive root systems of the flowering herbaceous plant material. Often irrigation is included to help the plants through the difficult times of the year.

INTENSIVE GREEN ROOF SYSTEM

An intensive vegetated roof system offers the greatest palette of plants from which to work with. These systems are generally anything over 12" in depth. Similar to a semi-intensive system, there are two layers of media, however, intensive systems are thick enough to support plant material that you would see in a traditional landscape. They can often support plants such as trees and shrubs. Frequently, these roofs go unnoticed as they blend into the landscape and are over structures such as parking garages and tunnels. Intensive systems generally need an integral irrigation system.


Green Roof Plants

Green Roof PlantsHardy, drought tolerant plants are best suited for green roof environments because they are more equipped to handle the weather conditions that exist on a roof. These plants are typically native to seashore, alpine, and desert regions and are therefore able to survive in environments often exposed to vast amounts sun, wind, and rain.

Green Roof Growth Development

Depending on the system used, green roof plants can take up to year to become fully established. This is why we supply two years of maintenance with our green roof installations. More about Green Roof Growth Development...
