Vegetative Roofing Systems
Vegetative roofing systems provide numerous benefits to the buildings and environments in which they are used including reduced heat island effect, lowered energy usage, and improved air quality. Live roofing can be incorporated into most designs and can add efficiency, aesthetics, and value to your building.
Although initially more expensive to install than traditional roofing, vegetative roofing provides a number of long term cost savings, may qualify for federal tax credits, and is a solution for increasingly prevalent storm water runoff regulations.
Intensive Vegetative Roofing Systems
Kalkreuth’s selection of intensive green roofs offer a great potential for design and biodiversity and can be used in a number of commercial, residential, or industrial applications.
Features
- Medium depth of 6 inches or more
- Often require heavy root barrier and irrigation
- Reservoir layer required
- Efficient drainage layer may be required
Options
- Wider selection of plant species than extensive systems
- Improves air quality
- Increases energy efficiency
- Improves aesthetic environment
- Aids in LEED Certification
Intensive, or deep, vegetative roofing systems support a diverse selection of plant species such as trees, shrubs, and other herbaceous plant varieties. Intensive systems can easily incorporate architectural features such as pavers, walkways, and benches.
Extensive Vegetative Roofing Systems
Extensive vegetative roofing systems combine the science of horticulture, waterproofing, and engineering to replicate the many benefits of traditional vegetative open space.
Features
- Growth medium of approximately 2-6 inches
- Sloped substrate to provide positive drainage
- Designed to provide excellent plant growth and water holding capacity
- Insulation layer
- Can include a loose-laid or partially-attached membrane
- Modular construction for ease of installation and dismantling
Options
- Prevents moisture from entering a habitable space or building
- Protects from ultraviolet (UV) exposure
- Improves water quality
- Conserves energy
- Improves aesthetic environment
- Aids in LEED Certification
Extensive, or shallow, vegetative roofing systems use a limited range of species such as herbs, mosses, low-growing grasses, sedum, and other plan varieties that tolerate extreme conditions. Sustained in a growth medium layer of approximately 2-6 inches, our extensive vegetative roofing system options provide many benefits such as water quality improvement and energy conservation.
