As much as we love green roofs for all of the economic and environmental benefits they offer, not all buildings can receive a green roof. Age of the building, roof accessibility and cost are all factors to consider before deciding whether to green roof your property.

Look below for your building type. If your building meets the criteria listed, then you are Roof Ready! Please contact us for an estimate on your new green roof!
  
 If the answers to the questions below are "No," green roofing may not be right for your building, or may not be feasible at this time.

• - Are you planning to replace your roof or waterproofing within the next year?
• - Is your rooftop relatively flat, or no more than 30-degrees of pitch?

• - Does your building have LEGAL roof access or a roof veranda or deck?
  • If you don't have a roof deck, was your home built after 1960?      
    
    If you don't have a roof deck and have a home built before 1960, have you had structural reinforcing or new roof joists installed in the last ten years?
    
    If none of the above apply, do you want to green roof an addition, garage, or out-building built within the last 15 years?

• - Is your rooftop sunny with relatively few or no trees growing above?
• - Can you afford to spend about $10-20 per square foot, in addition to the cost of replacing your roof with specialized waterproofing ($7-12/sf)? (D.C. home rooftops average about 600 sf.)
