We work hard to make sure that you’re green roof is healthy, weed free, and to 95% maturation before we deliver it. Our goal is for our clients to receive the green roof benefits immediately, with minimal time investment. Unlike conventional (plant in place) and mat (sod/carpet) systems that require a great deal more irrigation, monitoring, and maintenance after install, the LiveRoof hybrid system requires very little work to insure a successful and healthy green roof. The above video describes the simple maintenance routine required to safeguard your investment. (We recommend weeding 1-2 times a month, monitor irrigation regularly, and simple spring (fertilizer) and fall (trim) practices).
Before a green roof installation, it is important to design and implement an irrigation system. Green Roofs that are composed mostly of sedums require irrigation every 3 days during the growing season. (They also do require some moisture during the winter (dormant) season – this is usually attained from the snow/snow pack in our region.) Native grass roofs require irrigation (at least) every other day.
Upon install, our green roofs are sufficiently fertilized for the first year. It is good practice to fertilize your green roof with a 14-14-14 fertilizer every spring to insure plant health. In the spring, a trimming (mower/weed trimmer) is the recommended for sedum roofs, and a fall trim is important for grass and wildflower roofs. Because the modules are vegetated to 95% there is little weed encroachment, however, periodic weeding is necessary.

Intermountain Roofscape Supply, green roof plants are selected for proven performance in environmental extremes in the Rocky Mountain and Northwest Regions. They are, however, living organisms and different from static, nonliving elements of the roof and building. Accordingly, Intermountain Roofscape warrants its prevegetated green roof plants for one (1) year from installation on permanent residence homes. Intermountain Roofscape Supply will not warrant its prevegetated green roof plants that are installed on vacation, recreation, or second residence homes or properties where the owner is not present most of the year.
Conditions Required for Coverage:

e. poor irrigation water quality, lack of enough water (year round)
f. structural failure or damage of any type
g. physically moved modules (as in the case if modules were removed or moved for rooftop maintenance).
h. divots or plant displacement resulting from removal of large weeds (avoided easily by pulling weeds when they are small)
