Products / Authentik

Authentik is a concealed-fastener steel profile for roofing and siding with a 1 7/16 inch rib and optional striations or multiple ribs, in 16 or 20 inch covering widths and a 4 foot minimum length. It is made in a nail-strip model and a clip model, in 22, 24 and 26 gauge. On a roof it needs a solid substrate and a roofing underlayment, with a 3/12 minimum slope, or 1.5/12 where sealant is applied.
