Commercial roofing projects present a unique opportunity in Oregon – not just for structural upgrades, but for significant energy efficiency improvements. Failing to replace or add roof insulation means missing out on substantial energy savings and valuable incentives from Energy Trust of Oregon.

Once the roof on a commercial building is finished, the opportunity to add insulation and claim incentives evaporates. That’s why evaluating opportunities for roof insulation should be a standard part of your re-roofing project workflow. With Energy Trust cash incentives of up to $2.85 per square foot, there’s never been a better time to make insulation a priority.

To clarify, commercial roof insulation is any “above-deck” roof insulation that is continuous across the surface. This method is common in commercial flat roofing systems and is installed before the roofing membrane or surface is applied.

Commercial Roof Insulation Incentive

Energy Trust offers generous incentives for adding above-deck insulation during re-roofing projects:

• Up to $2.85 per square foot for roofs with no existing insulation or damaged insulation. Installed insulation must reach or exceed R-15.
• $1.00 per square foot for roofs with existing insulation of R-5 or less. Installed insulation must reach or exceed R-30 (or R-15 if site restrictions prevent greater insulation levels).

For a complete list of eligibility requirements, please review the commercial application forms on Energy Trust’s website.

Contractor impact and opportunity

If a re-roofing project moves forward without insulation, whether due to cost concerns, lack of awareness, or tight timelines, it’s a missed opportunity for both the contractor and the customer.

• Building owners lose out on long-term utility savings and upfront cash incentives.
• Contractors miss a valuable upsell opportunity that enhances project value.
• Once the roof is finished, retrofits are costly and impractical.

Best practices for contractors  

To ensure your customers and projects benefit from roof insulation incentives, follow these best practices:

Investigate and incorporate insulation from the start

• Identify damaged or waterlogged areas where existing insulation conditions could trigger eligibility. If existing insulation is significantly damaged, photos will be required prior to beginning work and pre-approval is recommended.
• Include insulation in your initial scope and bid.
• Educate building owners on insulation’s impact on energy bills and long-term savings.
• Take before, during, and after photos of the work.

Clarify that its “above-deck”

• Ensure clients understand that this isn’t attic or under-deck insulation.
• Above-deck insulation is installed between the roof deck and the new roof surface and must be continuous.

Document for cash incentives

• When submitting an application, include R-value specifications and product details.

The bottom line: don’t miss the moment

Re-roofing projects offer a one-time opportunity to add above-deck insulation. As a contractor, customers lean on you to identify opportunities to save and deliver value – not just in roofing, but in energy efficiency, cost savings, and smart long-term investments.
