It is common knowledge that a metal roof can last a lifetime; however, the actual length of time depends on the specific climate and weather conditions in California. Since California experiences extreme temperatures, this means that the wear and tear on a metal roof will vary from year-to-year.

Factors Influencing Metal Roof Longevity in California

Climate Conditions

California’s climate is known for its prolonged periods of hot, dry air paired with extreme temperatures. The effects of these conditions, combined with the state’s lack of significant precipitation, can cause damage to metal roofs from excessive exposure to the elements. For example, extreme temperatures can cause metal panels to expand and contract, which can cause them to warp and eventually leak. Additionally, UV and infrared radiation from the sun can cause metal to corrode and fade over time.

Regular maintenance on a metal roof is essential for keeping it in good condition and guaranteeing a long life. This includes annual inspections of all components to check for rust, corrosion, or other signs of damage, as well as cleaning the surface of dirt and debris regularly. Additionally, metal roofs should be sealed, caulked, and treated with protective products from time to time to help prevent water damage and leaks.
