What is LiveRoof?
The First and Only Hybrid Green Roof System, LiveRoof® combines the benefits of modular, plant-in-place, and carpet green roof systems.
LiveRoof® brand System Advantages:
Pre vegetated trays. The job is 95 % finished when leaving the job site. This allows the customer to immediately receive the cost saving benefits. No need to farm the roof like other methods. We can grow your material at the nursery to design specs prior to the time it's needed at the job site.
The patented tray and media help maintain the correct drainage and ph and are more aestically pleasing and beautiful to look at. Some commercial developers can receive more rental leasing dollars per square foot.
This system will help with the heat island effect and improve the life of your roof up to 20years longer. LiveRoof can absorb 1 inch of rainwater with no run off. All the remaining rainwater from storms are filtered and slowed down prior to running to the watersheds.
You can save up to 40 % on your energy bills.
Tax credits are available for this system. LEED Certified
Modular — Fast easy economical installation
Soil to Soil system with elevators so when removed plant life will hide and grow over all lips allowing no photodegradation.
Extreme Low Maintenance. Trays are easily replaceable if needed.
Green roofs are much better looking than asphalt, gravel or tar.
Natural views create more productive, healthy, happy, creative, relaxed people.
Green roofs expand the usefulness of buildings via patios, gardens and vistas. After all what was there before the building was built?
Urban Heat Island Mitigation. The urban heat island effect is the temperature difference between urban areas and their rural surroundings. The temperature differential causes air currents and dust, and even contributes to violent weather events within urban settings. Green roof vegetation helps by cooling the air, slowing air movement and acting as a substrate for pollution to settle out and detoxify.
Plants, soil, and air trapped in the soil are great acoustic insulators. Tests indicate that green roofs can reduce indoor sound by as much as 40 decibels, which is of great benefit to occupants of buildings affected by airports, industry, trains and traffic.
Water Conservation/Reduction of Storm Water Runoff:
The soil in green roof systems acts like a sponge and absorbs excess rainwater. Research has shown that extensive green roof systems can reduce runoff by up to 90+% annually (varies with climate, soil and pitch of roof).
Green roofs reduce the impact of each new building on the municipal storm drainage system and surrounding watershed. They reduce flooding, erosion and artificial heating of water which helps preserve fisheries and other aquatic life.
Green roofs reduce the need for on-site storm water management systems and according to Seattle based Magnusson Klemencic Associates, under certain conditions, can offset the cost of a green roof by 30 to 60%. When combined with an effective rain garden (bioswale), green roofs can make it possible to have zero discharge of rainwater from the site, therefore saving money by not having to connect to the storm sewer system.
Green roofs filter water prior to returning it to the aquifer. They buffer acid rain and remove nitrate pollution as water slowly percolates through the soil.
What runoff remains will usually occur hours after peak flows, providing additional time for sewer systems to handle the runoff burden from impervious surfaces.
Plants and soil help recreate habitat for butterflies, insects, and songbirds.
With an emphasis on recycled components, energy conservation, sustainability and minimal environmental impact (via development), green roofs score points with city planners, the community and tenants. This is oftentimes rewarded with zoning that allows for more intensive development. Building with green roofs may also receive tax credits or municipal grants and typically will command higher selling and rental prices.
Conservation of Municipal Septic Systems:
Sponging up excess rainwater means municipal septic systems do not have to be expanded as much. It also means reduced overflows as well as reduced pollution and associated costs. You also can reduce the size of your detention basins for your jobsite.
Extension of Roof Life:
Plants and soil act as a protective shield from the elements. This means:
No U.V. radiation/photo degradation of roofing components.
Minimal thermal contraction and expansion (green roofs can reduce temperature fluctuations by as much as 90%). Studies show that on a sunny 95°F day, conventional rooftop surfaces can reach 175°F. Green roofs bring these temperatures in line with the ambient air temperature.
Protection from drying winds.
Protection from mechanical damage.
Reduction or elimination of cracks and leaks.
Potential 200% - 300% extension of membrane life expectancy.
The evapotranspirative effect of the plants and four inches of growing medium typically reduces indoor temperatures 6 to 8 degrees during warm/hot weather and can reduce air-conditioning costs 25 to 50 percent in single story buildings. This not only allows for ongoing cost savings but an initial reduction in the size of the required air conditioning equipment.
Minimal insulation (R-Value) exists during cool or winter weather. The pore space of the growing medium tends to be more water saturated at this time, and the plants won’t be as large and therefore will not trap as much air (essential to insulation value). But, in snowy winter locations, the vegetation helps to trap blowing snow which adds insulation value.
How is it installed?:
First, the grower inserts the LiveRoof® Soil Elevator™ into LiveRoof® module.
LiveRoof® module is filled to the top of Soil Elevator™ with LiveRoof® engineered growing medium.
LiveRoof® Plants are grown to maturity approximately 1 inch above the LiveRoof® module.
Installer sets modules tightly in place on the roof within LiveRoof® recommended edge treatments.
LiveRoof® Soil Elevator™ is removed for a beautiful, seamless instantly mature green roof.
Water thoroughly to settle any loose growing medium and to get your LiveRoof® off to a great start.
