1How We Inspect a National City Roof
As a rule, a done right National City inspection starts at the flashings, not the field. Chimneys, vents, skylights and the swamp cooler curb fail long before the covering does. Photographs with dates are part of every National City inspection, because an undocumented claim gets read as wear and tear by any adjuster. A National City inspection should end with a itemised report and photographs, not a verbal summary and a price. In practice, drone access on steep or fragile National City roofs gets the detail without anyone walking a covering that cannot take it. We check the deck from inside the attic on every National City project. Daylight through the sheathing tells you more than anything visible from the driveway.
Streets in National City that were built out together tend to need roofs together, which is why one re-roof often brings three more on the same block. In practice, roof pitch across National City varies enough that the right material on one street is the wrong one two blocks away.

San Diego County is no different. On most jobs, tPO and modified bitumen both work on National City low-slope roofs, and the choice usually comes down to detailing rather than the sheet.
The majority of National City roofs that let go early let go at a penetration someone could have resealed for a few hundred dollars. Drainage is the cheapest maintenance on any National City building — blocked outlets cause more damage here than the storms themselves. We see it on National City roofs every week.

A National City estimate worth reading itemises tear-off, disposal, underlayment, covering, flashing, permit and clean-up separately. It is the same story on most National City streets. Financing makes sense on a National City roof covering that is actively failing; it rarely makes sense on one with years of life left. This holds across San Diego County.

In practice, actual cash value and replacement cost behave very differently on an older National City roof, and the policy wording decides which applies. In practice, 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.
