In Milwaukee, the life expectancy of roofing materials varies depending on the type and local climate conditions. Asphalt shingles, the most common choice, typically last 15 to 30 years, while architectural shingles offer a longer lifespan of 25 to 40 years. Metal roofing, known for its durability, can last between 40 and 70 years. For flat roofs, EPDM, TPO, and PVC materials generally last 15 to 30 years depending on maintenance. Wood shingles can last 20 to 40 years but may be affected by moisture. Premium materials like slate or clay tiles offer exceptional longevity, often lasting 50 to over 100 years, though they are less common due to their weight and cost.
