Standing seam roof panels have been used on roofs of traditional and contemporary homes for more than a century and these standing seam metal roofing panels are commonly used on roofs of commercial businesses because of the roofing's outstanding durability. These standing seam roof panels have area clean and graceful lines that have been an enduring favorite on a wide range of architecture. SL150 is a snap lock standing seam roof panel that installs with concealed clips. The snap-lock standing seam roof panel installation offers high levels of wind uplift protection and also allows these standing seam roof panels to float on the roof deck, allowing for expansion and contraction with temperature extremes. Compared to Advantage-Lok standing seam metal roof panels, SL150 standing seam roof panel ribs have a more narrow, knife-edge profile that some customers prefer on their metal roofs. SL150 standing seam roof panel ribs snap securely in place over the clip to provide your roof maximum wind and weather resistance.
