Cool Roof Incentive Program

Without significant changes in the development of Louisville's urban landscape, urban temperatures are expected to increase over the coming decades due to the greenhouse gas effect, the displacement of trees and other natural vegetation, and the expansion of concrete, asphalt and other impervious surfaces. Rising urban temperatures have implications for public health as well as critical infrastructure preservation. 

In an effort to start managing urban heat, Louisville Metro Government is offering a Cool Roof Incentive Program for both residents and businesses.

Cool Roof Incentive Program

The Office of Advanced Planning and Sustainability provides incentives to property owners of $1 per square foot of cool roof installed, with a goal of incentivizing at least 100,000 square feet of cool roofs. Buildings located in Metro Council Districts 1, 3, 4, 5, 6, 12, 14 and 15 are identified as high heat island areas based on the Urban Heat Management Study (2016) and will receive 70% of the available funding for Fiscal Year 2022. The program will continue until funds are depleted. Incentives are limited to a maximum of three properties per property owner per fiscal year.
