Whether you’re planning a replacement, comparing materials, or simply trying to understand what’s over your head, this guide breaks down roof lifespans by material, explains the different types of roofing systems, and highlights the key parts of a roof every homeowner should know.

At American Eagle Roofing, we most commonly recommend composition shingles, metal, or tile roofing based on our local climate. These materials are best suited to withstand both the snow loads of the Sierra and the heat of the valley.

We’ve found that roofs in high-snow areas like Tahoe or in high-wind zones of Northern Nevada tend to fail faster without the right materials or installation practices. Proper attic ventilation, underlayment, and fastening techniques are critical to roof performance in these conditions.

While metal has the best reputation for longevity, we also trust GAF roofing systems for their durability and unmatched warranties. GAF’s manufacturer-backed warranties cover both labor and materials, regardless of how the roof was installed, with labor coverage lasting up to 25 years. That kind of protection gives homeowners peace of mind for decades.

At American Eagle Roofing, we proudly install GAF HDZ RS Shingles, tile roofing systems, and metal roofs that are built for durability in both Tahoe’s snow and Sacramento’s heat.
