There are two main types of metal roofing. Let’s take a minute and explore the two. There are exposed fasteners roofing, and standing seam roofing. The exposed fasten is generally less expensive, is secured to the roof deck with screws, and it usually comes in 26 and 29 gauge. The standing seam metal is secured to its self from underneath. There are no screws, and it generally costs more than the exposed fasteners and usually is thicker. Let us help you choose the right type of metal for your project.
