As summer temperatures in Philadelphia continue to climb, many residents face the double challenge of extreme heat and rising utility costs. To help address these concerns, the Philadelphia Office of Sustainability and the Energy Coordinating Agency (ECA) have partnered to launch a new “cool roof” pilot program in select neighborhoods.

The initiative focuses on a simple but powerful solution: painting rooftops white. This reflective coating is designed to lower indoor temperatures by reducing the amount of heat absorbed by traditional dark roofing materials.

Where the Pilot Program is Taking Place

The pilot will roll out on 150 homes in the Strawberry Mansion neighborhood. The ECA will carefully track both indoor temperatures and utility bills to measure the program’s impact. By comparing energy usage before and after the installation, officials hope to demonstrate how cool roofs can:

• Reduce reliance on air conditioning

• Lower monthly energy bills

• Make homes more comfortable and livable during heat waves

Why Cool Roofs Matter

Philadelphia, like many cities, struggles with the urban heat island effect, where densely built neighborhoods trap heat and create higher-than-average temperatures. For residents—especially those in older homes with limited insulation—this can make summer living not only uncomfortable but also unsafe.

The cool roof pilot program aims to provide relief while exploring a cost-effective, environmentally friendly way to reduce energy use and promote sustainability.

How to Learn More or Apply

Homeowners interested in the program can learn more and apply through the Energy Coordinating Agency’s website.

This program is just one example of how Philadelphia is working to create healthier, more energy-efficient housing options while supporting families with the rising costs of homeownership.
