How Does the Local Climate Affect the Frequency of Roof Replacement in San Jose?

Nested in the center of the Santa Clara Valley, San Jose is characterized by a Mediterranean climate. Scorching summers and winters with high precipitation levels can be tough on roofing materials. Add intense sunlight and UV radiation for eight months, and it becomes clear why poor-quality shingles can fade, become brittle, and crack over time. On top of that, winter rains can lead to issues like mold and rot. Consequently, homeowners may need to replace their housetop more frequently than in milder climates to prevent leaks and structural damage while keeping energy efficiency at a decent level.

Flashing Installation

Flashing is critical for preventing water leaks. It is installed around areas prone to water accumulation, such as valleys, chimneys, and roof edges. The complexity of the flashing installation and its material composition can cause the price to fluctuate from $16 to $28 per linear foot.
