2Pricing a National City Roof Honestly

On most jobs, cost on a National City roof comes down to size, pitch, how many layers come off, and what the deck looks like underneath. A National City roof covering quoted without anyone looking in the attic is a written price based on half the information. That is as true in National City as anywhere in San Diego County. Square footage is only half the cost of a National City roof covering; pitch, access and layer count move the number as much. The variable line on any National City quote is deck repair, and it should be priced per sheet in writing rather than hidden in an allowance. A National City estimate that comes in far below the others is usually missing the flashing, the permit or the disposal. San Diego County is no different.

Most National City claims that fail do so since the damage was cleaned up or patched before anyone photographed it. This holds across San Diego County. On most jobs, policies covering National City properties generally pay for sudden damage and not for age, so the report has to separate the two clearly. 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.

As a rule, granule loss in the gutters is the earliest honest signal on a National City shingle roof, and it shows up years before a ceiling stain does. San Diego County is no different. We look over the deck from inside the attic on every National City job. Daylight through the sheathing tells you more than anything visible from the driveway. We photograph every elevation on a National City work so the written estimate can be read against what is actually up there. Worth knowing before you sign anything.
