Last updated: September 24, 2026

The arid conditions prevalent for much of the year in San Diego can lead to expansion and contraction stresses on metal roof panels, potentially compromising sealants and fasteners. When the infrequent but forceful winter storms arrive, these vulnerabilities are exposed, leading to leaks. Proper installation, including appropriate underlayment, screw placement, and panel overlap specifications as outlined by manufacturers and industry best practices, is critical for long-term performance. Attention to detail in flashing around penetrations like vents and chimneys, which are common in the diverse housing stock found from coastal areas to inland valleys, directly impacts water ingress prevention.
