Snap-Loc Panel Roofing
The snap-loc panel metal roofs are standing seam metal roofing systems. They are formed and installed like the mechanically seamed systems without the need for the mechanical seaming. These panels snap into place over one side of the adjoining panel.
The difference is that the seams are fatter due to the bends in the formed overlapping seam. They can provide a higher wind uplift rating because a much larger attachment clip can be used. Since the panels are not folded into each other there is far more room for a much heavier sized clip. Englerts Series 2000 system is rated for 200 plus mph winds. This rating exceeds the ratings of any other system or roofing type that is available to the market.
Any metal roofing panel is perfect as a roof covering component. As with all roof systems, the proper attention has to be paid to the flashing details. These details are the heart of the metal roof. Since colored metals cannot be welded together at some of the detail intersections, the proper adhesive sealants are required. They must be flexible to handle the thermal expansion. They must be UV light resistant. And, if they do not come in the same colors
as the panels, they should be paintable. Most of the warranted panel coatings require a tripolymer type adhesive sealant to be used.
The colors are all the same and the classifications of warranties are equally similar. As long as the proper metals are used, the panels are kept clean from the possible buildup of debris and the chance for surface abrasion is eliminated, these roofs will last what will seem a lifetime.
