Most residential roofs last between 15–50 years, depending on material, maintenance, and climate. For example, asphalt shingles last 15–30 years, while slate roofs can last over 100 years.
The lifespan of your roof isn’t just about what it’s made of, but how it’s installed and cared for plays a huge role too. A well-maintained roof can easily outlast a neglected one, no matter the material. Regular inspections, prompt repairs, and proper attic ventilation all contribute to maximizing your roof’s longevity. Harsh weather, heavy storms, and blazing sun can speed up wear and tear, making it even more important to choose the right roofing material and invest in routine maintenance. Ultimately, understanding these factors can help you protect your investment and ensure your roof stands strong for decades to come.
