Roofs Made Seamless, Life Made Simple

A Technology Evolution

Over three decades ago, WeatherWeld set about developing a roof technology that would blend the best of the popular roofing methods in use. This led to a superior process that emphasizes flexibility, strength and a seamless surface with no gaps or spaces for water to penetrate. WeatherWeld installation pros use a patented applicator to create a roof designed to last the entire lifetime of the building. In over two decades since this industry evolution, our roofs are still protecting as well as ever!
