Weather Shield Roofing Systems is West Michigan's leading commercial re-roofing specialist. As a professional roofing contractor since 1980, it amazes us how few roofs ever reach a ripe old age before needing replacement. An unbelievable 91.1% of roofs fail prematurely! Here's a principle to live by when it comes to deciding on a new roof: The greatest cost of roofing is actually the hidden cost of having to re-roof prematurely. Weather Shield Roofs are Built to Last. We design our premium system for a 20-25 year life expectancy, almost double the average life. Our roofs are built to die of old age, not the 91.1% of problems that cause lesser roofs to fail. In 20 years, your Weather Shield Roof will be doing the same thing it does today...keeping you dry.
