1How We Inspect a National City Roof

A National City roof covering is inspected from the attic as well as the roof surface; half the evidence is underneath. We see it on National City roofs every week. As a rule, flashing at the wall junction is checked first on any National City inspection, given that that is where most ceiling stains originate. A National City inspection should end with a written report and photographs, not a verbal summary and a price. Water readings matter on National City low-slope roof coverings. Coating over wet insulation seals the trouble in rather than solving it. Deck fastener pull-through is checked on older National City roofs, since the sheathing often fails before the shingle does. Infrared scanning on a National City commercial roof locates wet insulation that no visual inspection would find. That is as true in National City as anywhere in San Diego County.

Supplements are normal on National City claims once the covering is off and the deck is visible, and they should be raised with evidence rather than argued later. We work alongside the adjuster on National City claims rather than around them, which keeps the scope honest and the timeline shorter. Wind load and storm damage on a National City roof covering is covered where it is documented; wear is not covered anywhere.
