Green Roofs
What is a green roof? Landscaping on roofs? Reflective roofs? Energy efficient roofs? Recycling and reuse of existing roofing materials? All of the above.
GARDEN ROOFS
:
Roofing systems that are covered by landscape systems. Advantage - Reduces urban heat effect, and ground water run off. Protects roof system from ultraviolet exposure and reduces the effect of thermal cycles on the roof system. Disavantage - Requires a structure that can hold greater weight, needs landscaping maintenance and is difficult and expensive to find roof leaks.
REFLECTIVE ROOFS
:
Roofing systems that reflect more heat than they absorb. TPO and PVC are most commonly used reflective membranes. Advantage - Reduces cooling costs and urban heat effect. Disadvantages - Many of these membranes require annual cleaning to maintain their reflective qualities.
ENERGY EFFICIENT ROOFS
:
Roofing systems that incorporate insulation that meets or exceeds state energy code of R = 22. Advantages - Reduces cooling and heating costs. Usually recoup cost of insulation in energy savings within the first 10 years. Disadvantages - May require building up roof perimeter and or curbs for roof top units.
RECYCLING OR REUSING EXISTING PRODUCTS
:
Some PVC and EPDM products are starting to be recycled. Existing insulation can often be reused in the new roof system. Advantages - Reduces the amount of existing products going to the land fill. Reduces the cost of additional insulation to meet energy code. Reduces the cost of labor on the project. Disadvantages - Wet insulation must be removed to prevent possible premature failure of new roofing system. Existing insulation may not be as energy efficient as newer insulation, which could add to the cost of perimeter edge and penetration details.
Selecting the best green approach for you is as unique as your building.
Factors such as budget, project location, weight bearing capacity and long term goals must be considered.
