High-Performance Roofing Checklist

While there are no established standards for the newly evolving category of High-Performance Roofing systems, there are key questions that building owners can ask to determine if a roofing system satisfies criteria under each of the Five E’s of HPRs.

HPR 1: Energy

• Does the roof meet ENERGY STAR criteria?
• Have you determined potential energy savings using EPA ENERGY STAR online calculator?
• Does the roof meet the ASHRAE 90.1 standard, making it eligible for Federal tax deductions?
• In California, does the roof meet the requirements of Title 24?

HPR 2a: Environment/External

• Is the roof certified by the ENERGY STAR Roofing Products Program?
• Does the roof earn points toward USGBC LEED credits?
• Is a system/material LCA available?
• Is a roof tear-off required?
• How many runs to the local landfill are needed with this roofing system?
• Is the roofing material recyclable?
• Does the roofing manufacturer have a recycling program?

HPR 2b: Environmental/Internal

• Does the roof system moderate temperatures in summer and winter, even w/o air conditioning?
• Does your roofing system provide one- or two-way ventilation?

HPR 3: Endurance

• What is the roofing manufacturer’s reputation? How many years in business?
• What is the range of service longevity for this type of roofing system with this manufacturer in this area? Other areas?
• Does the manufacturer inspect the roof after installation?
• Local references for manufacturer? Contractor?
• What is the roofing contractor’s reputation? How many years in business?
• Are contractor employees fully trained, supervised at job site?
• Does the manufacturer train, monitor, grade the contractor?
• What have been the primary reasons for system failure with this type of roof? How were they resolved?
• How long is the warranty?
• Does it cover the entire roofing system, including installation defects?
• Exclusions and fees in the warranty? (Ponding water? Free repair/replacement in case of failure? Consequential damages?
• Maintenance/repair: How often? How much? How easy? Local references?

HPR 4: Economics

• Can you provide an LCC analysis that includes installation costs, tear-off and disposal, estimated maintenance and repair and potential energy savings over the life of the roof?
• What are the estimated maintenance and repair costs per year?
• Does this roofing system require tear-off and disposal?
• Is this a custom pre-fabricated system that can be installed more quickly with less labor and reduced waste-related expenses?

HPR 5: Engineering

• Is this the best roofing system for my roof deck? My building? This climate?
• Has drainage been adequately designed to ensure water runoff?
• Does the roof meet all local roofing code specs?
• Is custom pre-fabrication an option?
• Are roof materials energy efficient, environmentally friendly, durable?
• Is the roofing material naturally fire resistant?
• Can you provide a wind calc for me?
• Is this a fully integrated roofing system that provides watertight performance while enhancing the performance of other building components?
