Grants for green and cool roofs

Since 2009, the City's Eco-Roof Incentive Program has helped fund the installation of more than 100 green and cool roofs on buildings across the city.

Eligible green roof projects will receive $75 / square metre up to a maximum of $100,000.

Eligible cool roof projects will receive $2 - 5 / square metre up to a maximum of $50,000.

Applications are currently being accepted for residential, industrial, commercial and institutional buildings. Please submit your application before work on the roof commences.

Eco-roof overview

  

What is an eco-roof?

An eco-roof may be either a green roof that supports vegetation, or a cool roof that reflects the sun’s thermal energy.

A green roof is a roof surface that supports the growth of vegetation over a substantial portion of its area for the purpose of water and energy conservation. It is comprised of a waterproofing membrane, drainage layer, organic growing medium (soil) and vegetation.

A cool roof is a roofing system with an exterior surface with high “solar reflectivity” and “thermal emissivity” that reflects the sun’s rays and reduces heat build-up from the sun’s thermal energy. A cool roof can be either a coating applied over an existing roof system or a new single-ply waterproofing membrane.

What are the environmental benefits of eco-roofs?

The environmental benefits of eco-roofs are many. Green and cool roofs help reduce urban heat and associated energy use, which is a particular concern as global temperatures rise. Green roofs also help manage stormwater runoff (reducing the pollutants that enter our waterways), enhance biodiversity, improve air quality, and beautify our city.

Adopted by City Council in 2009, the Eco-Roof Incentive Program is a key element of the City’s Climate Change Action Plan, an aggressive environmental framework aimed at reducing Toronto’s greenhouse gas emissions by 80 per cent by 2050.

Eligibility

  

What buildings are eligible?

The Eco-Roof Incentive Program provides funding for existing buildings, and new buildings not subject to the Green Roof By-law. The program was expanded in 2012 to include new and existing Toronto Public and Separate School Board buildings.

Buildings must be located in the city of Toronto.

Specific requirements for green roof and cool roof projects are provided below.

What cool roof projects are eligible?

The Eco-Roof Incentive Program provides funds for cool roof projects on:

  • existing residential,  industrial, commercial, and institutional buildings

 

cool roofCool Roof Description: A roofing system with high solar reflectivity and thermal emissivity to reduce the urban heat island effect and can be either a coating applied over an existing roof system or a new waterproofing membrane that meets the performance specifications outlined below.

 

 

 

 

To be eligible for the Eco-Roof Incentive Program, a Cool Roof must meet the following specifications:

  1. Cover 100% of the roof area of the building, excluding mechanical equipment or other environmental technologies.
  2. Be comprised of a roof material or coating system that:
    • has a minimum Solar Reflectance Index (SRI) rating of 78 for low sloped roofs. Low sloped roofs have a surface slope less than 16.7% (9.5 degrees).
    • has a minimum SRI of 29 for steep slope roofs. Steep sloped roofs have a surface slope greater than 16.7% (9.5 degrees) and less than 41.7% (22.6 degrees).
    • has an emissivity greater than 0.9 and an initial solar reflectance of 0.65 (equivalent to an SRI of 78).
    • is asbestos and mercury-free and emits zero volatile organic compounds (VOCs) and ozone depleting substances (ODSs).

What green roof projects are eligible?

The Eco-Roof Incentive Program provides funds for green roof projects on:

  • existing residential, industrial, commercial, and institutional buildings
  • new residential, industrial, commercial, and institutional  buildings with a gross floor area of less than of 2,000 m2.
  • new and existing Toronto Public and Separate School Board buildings of any size

 

green roofGreen Roof Definition: An extension of an above grade roof, built on top of a human-made structure, that allows vegetation to grow in a growing medium and which is designed and maintained in accordance with the Toronto Green Roof Construction Standard (Toronto BY-law 583-2009).

 

 

 

 

To be eligible for the Eco-Roof Incentive Program, a Green Roof must meet the following specifications:

  1. Be designed and constructed in conformance with the requirements of the Toronto Green Roof Construction Standard.
  2. Will have minimum coverage of available roof space* in accordance with the following chart:
Gross Floor Area
(Size of Building)
Minimum Coverage of Available Roof Space
(Size of Green Roof)
Less than 4,999 m² 20%
5,000-9,999 m² 30%
10,000-14,999 m² 40%
15,000-19,999 m² 50%
20,000 m² or greater 60%
* Available roof space is defined as the total roof area minus areas designated for renewable energy devices.

Application Process

 

How do I apply for funding?

 

Please Note: Green and cool roof projects that have already started or are complete are not eligible for funding. You must receive approval of your application prior to the work on the roof commencing.

Prospective applicants are encouraged to contact the Eco-Roof Program Coordinator in advance of their application to discuss their proposals (Annemarie Baynton: abaynto@toronto.ca or 416-392-1848).

What supporting documentation is required for green roof applications?

In addition to completing the online Application Form, Green Roof applicants must also submit the following supporting documentation:

  • A photo of the roof prior to construction.
  • Detailed plans of the proposal showing percentage coverage, plant material and type of growing medium and construction details.

These items can up uploaded via the online form or emailed to abaynto@toronto.ca

The City reserves the right to request additional supporting documentation.

What supporting documentation is required for cool roof applications?

  • A photo of the roof prior to construction.
  • Detailed plans of the proposal showing percentage coverage, cool roof materials and manufacturer documentation and construction details.
  • A 5 year maintenance plan and contract or equivalent assurance that includes:
    • at minimum, an annual roof cleaning
    • an annual roof condition assessment and resulting maintenance; all subsequent roof maintenance must meet the cool roof specifications as outlined in the terms and conditions.
    • if applicable, re-coating of cool roof spray as per the life expectancy of the material or site conditions
    • the inclusion of all maintenance recommendations provided by the manufacturer or materials supplier.

These items can up uploaded via the online form or emailed to abaynto@toronto.ca
