Seasonal demand in National City affects scheduling more than price, but booking ahead of the rains helps both. San Diego County is no different. Budgeting a National City replacement a few years out costs nothing and removes the pressure of choosing a contractor during a storm. This holds across San Diego County.
Thermal cycling does the damage in National City — hot afternoons, cool nights, and materials expanding and contracting against their fixings all year. Low-slope sections in National City hold high temperatures worst, which is why coatings and reflective membranes pay for themselves here. It is the same story on most National City streets. On most jobs, dry offshore winds reach National City through autumn, lifting shingle tabs and ridge caps in the direction roof coverings are least lapped to resist.
