\u00a0\u00a0\u00a0 Are you thinking about putting a new roof on your home?\u00a0 Or perhaps you have a garage or other out-building that needs a new roof.\u00a0 You may want to consider installing a Green, or \u201cLiving Roof.\u201d\u00a0\u00a0\u00a0 We were intrigued by the idea and created one on our cabin.<\/span><\/span><\/span><\/p>\n

\u00a0\u00a0\u00a0 A Green Roof provides many benefits.\u00a0 It can provide increased energy efficiency by adding extra insulation to buildings.\u00a0 By having one less dark surface absorbing the sun\u2019s rays, and with the addition of transpiring plants, you can help reduce the \u201cheat island effect,\u201d that causes increased temperatures in urban areas.\u00a0 The growing media and plants absorb water, decreasing the amount of water run-off to storm drains.\u00a0 By planting a diversity of flowering plants, your Green Roof will attract birds, butterflies and other insect pollinators, thereby creating a charming microhabitat.\u00a0 Finally, your Green Roof can provide a pleasant view for those who look down upon it.<\/span><\/span><\/span><\/p>\n

\u00a0\u00a0\u00a0 There are some important questions to consider before you decide to build a Green Roof.\u00a0 Most importantly, will the structure withstand the weight of the plants, media, water and a snow load?\u00a0 Some structural reinforcement may be necessary– you should consult an engineer to be sure.\u00a0 If the slope of your roof is steep, special frames need to be constructed to prevent slippage.<\/span> <\/strong>\u00a0\u00a0For slopes less than 2 degrees, adequate drainage is a problem.<\/span> <\/strong><\/span><\/span><\/p>\n

\u00a0\u00a0\u00a0 The first step in the actual construction is to build a containment frame with drainage outlets on the lower edges.\u00a0 Next you will need a waterproof\/ root-proof membrane.\u00a0 (We purchased a pond-liner on \u201cCraig\u2019s List.\u201d)\u00a0 It is extremely important that you are careful not to make holes in this material and do a good job sealing seams.\u00a0 For roofs with less than a 10-degree slope, you will need a drainage layer and a filter layer (to prevent soil from clogging the drainage layer).\u00a0\u00a0 Next is the growing media.\u00a0 To limit the weight load, it is recommended that 75-90% of the media is inorganic, such as pumice or expanded clay.\u00a0 We tested the weights of various mixes and ended up using a mix of 40% lava rock, 40% perlite, 10% compost, and 10% coconut fiber (+organic fertilizers).\u00a0 The depth (deeper =heavier!) of your growing media will determine what you will be able to plant.\u00a0 At depths of 2 inches or less, you will only be able to grow mosses and sedums.\u00a0 At 2-4 inches you can plant short, drought tolerant grasses, wildflowers, and small bulbs.\u00a0 At 4-8 inches, you can plant taller species and even small hardy shrubs.\u00a0 <\/span><\/span><\/span><\/p>\n

\u00a0\u00a0\u00a0 The biggest expense is the plants and growing media constituents\u2014for us it was the perlite (we kept buying out all the local Home Depot stores!).\u00a0 I planned ahead and grew most of our plants.\u00a0 Your costs increase dramatically, if you have to purchase plants and\/or pay for the labor to install it.<\/span><\/span><\/span><\/p>\n

\u00a0\u00a0\u00a0 There are many resources on the web such as greenroofs.com<\/a> and livingroofs.org<\/a>.\u00a0 A good book to check out is \u201cGreen Roof Plants: A Resource and Planting Guide\u201d<\/i> by Edmund and Lucie Snodgrass.\u00a0 One thing to keep in mind is that these resources are from other climates.\u00a0 When deciding on plants to include in your plan, you should choose ones that will thrive in this climate.\u00a0 I tried to stick mostly with beach, prairie and subalpine natives, and several varieties of sedums, but I also planted various bulbs and scattered miscellaneous herb seeds.<\/span><\/span><\/span><\/p>\n

\u00a0\u00a0 It was a great joy, last summer, to visit the roof and see the busy activity of the bees and butterflies visiting flowers on our living roof!<\/span><\/span><\/span><\/p>\n
