Understanding the Lifespan of Commercial Roofing Materials

Different commercial roofing materials have varying lifespans. When considering commercial roof construction or replacement, it’s important to understand the longevity of each material and how it aligns with your needs. Here’s a breakdown of the lifespan for some common commercial roof materials:
