5How We Inspect a Duarte Roof

Put simply, a Duarte roof is inspected from the attic as well as the roof covering surface; half the evidence is underneath. Flashing at the wall junction is checked first on any Duarte inspection, since that is where most ceiling stains originate. We inspect the deck from inside the attic on every Duarte job. Daylight through the sheathing tells you more than anything visible from the driveway. Moisture readings matter on Duarte low-slope roofs. Coating over wet insulation seals the problem in rather than solving it. We photograph every elevation on a Duarte job so the documented estimate can be read against what is actually up there. Put simply, infrared scanning on a Duarte commercial roof covering locates wet insulation that no visual inspection would find. It is the same story on most Duarte streets.

Most roofs in Duarte fall into three groups: original coverings near the end of their working life, replacements from the last two decades, and low-slope sections added later. Original decking on older Duarte homes is often skip sheathing, which changes what can be laid over it. On most jobs, solar arrays on Duarte roofs complicate replacement, and the panel age rarely matches the roof age. Multi-unit buildings in Duarte usually need a low-slope system and a maintenance plan rather than a one-off repair. Los Angeles County is no different.
