The lifespan of different types of roofing systems varies by material. For example, asphalt shingles usually last up to 20 years, while metal roofing can far surpass that with longevity of 50 or more years - sometimes as long as 70! However, many factors affect the longevity, such as the quality of the roofing material, the skill of the installment team, and your ability to provide maintenance over time.
