A: Yes. Eco roofs vary widely in size, weight and design; no two green roof systems are the same. Ultra light systems, also known as extensive green roofs, work on most and are reserved for sedum plants; they are more cost effective and require irrigation. At the other end of the spectrum, a soil system gives you far more options for planting or urban gardening, but requires proper support or a stronger structure.
A: A roof garden can be installed on almost any type of roof as long as the structural loading capacity will allow for it. Contact us for a free, on-site assessment from one of our structural engineers.
A: No. Any leakage is typically traced to a waterproof membrane problem or a puncture in your actual roof; a roof garden installed properly will never have any leaks. For preventative measures we strongly suggest you contact a roofing contractor with solid experience to assess the condition of your roof membrane before installing an eco roof. Ultraviolet light from the sun causes the roof membrane to deteriorate over time, leaving you susceptible to leaks.
A: No. Those with a green thumb will find them surprisingly easy to maintain. As long as they have a little water and are checked 3-4 times a year for weeds, a lush and healthy green roof can be expected for a long period of time. We can also help. You will not regret bringing urban farming to your doorstep!
A: Yes. Any green roof system that is constructed voluntarily is eligible for a grant. However, you will need to complete some paper work and provide the necessary documents from your engineer and designer with your application. Please see our grants section for additional links to the eco roof incentive program.

In April 2012, the City of Toronto enacted the first Green Roof By-law in the world. This policy aimed to promote sustainable storm water management, combat climate change and create green jobs. For additional information about the Green Roof By-law and to determine if you are obligated to construct a green roof for your project, please visit the City of Toronto green roof website.
A: Whether you have to re-roof largely depends on the condition and age of your roof. We recommend re-roofing if your roof membrane is 10 years or older. On the bright side, your urban gardening roof will offer long lasting protection to your membrane. This means you most probably will not have to re-roof in your lifetime!
