A roof system energy audit is an analysis of the energy saving potential of an entire roof system, based upon the life-cycle cost analysis of the following components;
- Insulation type and quantity
- Surface coatings and finishes
- Vapor retarders and air barriers
- Roofing material quality
- Type and weight of roof-mounted renewable/sustainable energy systems
More specifically, a roof system energy audit will help you identify:
- How much and what type of insulation should be used, and how do you optimize insulation performance while maintaining compliance with all fire-related building codes?
- How relevant is reflectivity to energy savings, given your particular climate?
- Will your roof assembly require vapor retarders or air barriers to prevent condensation? If so, what type of system will be most effective giving the building's function and environment?
- What roofing materials will provide the optimum balance of waterproofing integrity and sustainability given the particulars of your facility's function and climate?
- What types of rooftop renewable/sustainable energy systems will a particular facility accommodate, and how are they likely to affect rooftop waterproofing performance?
- Which combination of roof and sustainable systems will best help you achieve your long-term goals?

What Will an Energy Audit Tell Me?
At the completion of an energy audit, you should have a detailed comparison analysis of at least two different types of roof, as well as the initial costs to install the roofs, and the projected long-term energy costs for each roof.
When you use less energy, you leave a smaller carbon footprint. In addition to analyzing the utility costs over the life of the roof, an audit estimates the amount of Carbon Dioxide (CO2), Methane (CH4) and Nitrogen Oxide (NOx) emissions that result from the energy demands of the competing roofs.
Initial Cost vs. Life Cycle Costs
In some cases, the least expensive roof can end up costing you much more in the long run. That's why it's essential to compare installation costs with the long-term expenses associated with different roof systems. Low initial costs can result in higher maintenance fees, increased energy usage and a shorter roof life.
Armed with your energy audit results, you can make an informed decision based on roof performance and lower utility costs. Quantifying the total life cycle cost of your roof offers you the best long-term value and savings.
