As a rule, infrared scanning on a National City commercial roof covering locates wet insulation that no visual inspection would find.
Attic temperatures in National City drive shingle life as much as the weather above does, which is why ventilation matters more here than the brochure suggests. That is as true in National City as anywhere in San Diego County. Debris in National City valleys holds what little moisture arrives against the covering, which is where rot usually starts. Worth knowing before you sign anything. On most jobs, a light-coloured covering in National City measurably lowers attic temperature and takes load off the air conditioning.
