• Roof Condition

  • Roofs should be evaluated and confirmed to be able to handle the additional live and dead loads of adding a PV system.

  • Roof age should be evaluated to determine the useful life of the roof.

  • Customers are financially responsible for the cost of removing and reinstalling their system if and when they need to repair or replace their roof during the contract period. The customer should be made aware of the current condition of their roof and expected number of years left in their roof. This will help inform the financial decision of whether they would like to re-roof now or in the future.

  • Consult with a professional roofer on the current condition and expected life of a potential customer’s roof when necessary.

  • If a roof is reported to be within 10 years of the end of its useful life, based on customer provided information regarding last reroof date and roofing material warranty, a re-roof should be pursued.

  • If the roof appears to have less than 10 years of useful life but the customer wants to move forward without a reroof, an EverBright roof waiver is required.

  • Plywood or other permanent layer should be present above the rafters and below the roofing paper and roofing materials.

• Low Slope Roofs:

  • Any roof under 2/12 (9.5 deg) is considered a low slope roof. A low slope roof should have the appropriate roofing material installed. TPO, EPDM, Foam, rolled comp, modified bitumen are acceptable. Any type of shingle is not acceptable due potential leaks. If you encounter a low slope roof that has shingles, it should be reroofed prior to installing solar. Proper low slope roof mounts should also be used for installation. Manufacturers data sheets and documentation should be reviewed to confirm mounts can be installed on low slope roofs.

• Prohibited Roof Types:

  • Wood Shake

  • Cal Shake

  • Slate Tile

  • Metal Shingle

  • Copper

  • More than 2 layers of composition shingles

  • Any home with faulty or defective roofing products. These can include, but are not limited to, Cemwood, certain Monier Tiles, Caland Hardy shake, and others that have had class-action lawsuits brought against them regarding asbestos and other issues.
