Roof and attic: Energy Trust has you covered!


Energy Trust will increase incentives for Home Retrofit and side-by-side multifamily insulation projects this fall. Customers can receive increased incentives for qualifying wall and floor insulation projects starting October 1, 2024. Attic insulation incentives remain unchanged. The increased incentives will become the new standard amounts going forward.

Please see the table below for updated incentive amounts. Note there are no changes to requirements or incentives for insulation in stacked multifamily properties.
