Skylight seals on National City roofs want checking annually, as they fail quietly and drip into the ceiling cavity. On most jobs, clearing the National City gutters in late autumn prevents most of the damage the first storm would otherwise cause. San Diego County is no different.
Material choice changes a National City roof budget less than most owners expect; labour and complexity dominate. Warranty terms affect the real cost of a National City roof more than the headline figure does. Worth knowing before you sign anything. Put simply, 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.
