Understanding Roof Longevity in California’s Unique Climate

Dr. Emily Carter (Building Materials Scientist, California Roofing Institute). “In California, the lifespan of roofs can vary significantly depending on the materials used and the local climate. Generally, asphalt shingles last around 15 to 30 years, while tile roofs can last over 50 years. Factors such as UV exposure, temperature fluctuations, and coastal moisture play crucial roles in determining longevity.”

Mark Thompson (Licensed Roofing Contractor, Thompson & Sons Roofing). “From my experience, roofs in California are often subjected to harsh weather conditions, including intense sun and occasional heavy rains. This means that while a roof may be rated for a certain lifespan, regular maintenance and inspections are essential to ensure it reaches its full potential, typically around 20 to 25 years for asphalt and 30 to 40 years for metal roofs.”

Hi, I’m Victor - the voice behind Element Roofing.

For over 15 years, I worked as a hands-on roofing contractor across northern Vermont. I started out swinging hammers with a local crew just outside of Saint Albans, learning the trade the hard way in the dead of winter, on steep-pitched roofs, under slate tiles that cracked if you looked at them wrong. Eventually, I launched my own small operation, Element Roofing, and spent the better part of a decade installing and repairing roofs across Sheldon, Swanton, Burlington, and all the small towns in between.

But people wanted to understand what was happening over their heads. They asked smart questions. They wanted to make good decisions but didn’t know where to start and too often, the industry gave them sales pitches instead of real answers.

My goal is simple to close the gap between tradespeople and homeowners, to demystify roofing without dumbing it down, and to give people the confidence to care for one of the most important (and expensive) parts of their home.

So feel free to dig in, explore, and take control of what’s over your head. We’re here to help from rafter to ridge.
