Put simply, cost on a National City roof covering comes down to size, pitch, how many layers come off, and what the deck looks like underneath. A National City quote that comes in far below the others is usually missing the flashing, the permit or the disposal. On most jobs, deck replacement on a National City job is unknown until the tear-off, which is why it belongs in the contract as a per-sheet rate. Square footage is only half the cost of a National City roof covering; pitch, access and layer count move the number as much. In practice, seasonal demand in National City affects scheduling more than price, but booking ahead of the rains helps both.

On most jobs, unpermitted roofing in National City surfaces at resale. the county or city building department covering National City keeps the record, and a buyer's inspector knows to look for it. the county or city building department covering National City handles the paperwork for roofing work in National City, and a licensed contractor pulls it as part of the project rather than leaving it to the owner. Realistically, the permit record for a National City property is public, which is how a buyer's inspector checks the roof was done properly. Worth knowing before you sign anything.
