Commercial Roofing in Gilbert

Does a Gilbert re-roofing project require an ASTM E1918 reflectivity test?

Yes. Gilbert enforces the 2018 AECC Section C402.3 requirement - minimum 0.65 initial solar reflectance per ASTM E1918 for low-slope commercial buildings above 2,000 sq ft at permit closeout. We include the reflectivity test as a standard part of every Gilbert commercial re-roofing closeout.
