Snap-Clad metal roofing panels feature architectural aesthetics as well as structural performance. Snap-Clad panels, produced in continuous lengths, are leveled to provide superior flatness and feature an optional factory-applied sealant bead for improved weather resistance. Maximum panel length is 64’ and minimum panel length is 4‘. Consult factory for longer lengths. Note: Minimum length for panels produced in the Annapolis Junction, Md., facility is 60 inches.
Each metal roofing panel features a 1-3/4” leg height and a continuous interlock for improved structural performance and wind resistance. A concealed-fastener clip system allows for thermal expansion/contraction while providing extraordinary hold-down strength. Two clips are available: a standard clip for most mansard and fascia applications, and a high-performance clip for roofing applications and UL 90-rated assemblies.
Trim
All flashing and trim shall be fabricated by manufacturer or qualified fabricator. Flashing shall be PAC-CLAD aluminum (.032 – .063 gauge as specified) or PAC-CLAD steel (24 gauge or 22 gauge as specified). A 30-year non-prorated finish warranty can be supplied covering finish performance. Vinyl masking is recommended on all fabrication applications where extra handling is expected. NOTE: The strippable film must be removed immediately after installation.
Installation
Snap-Clad panels are intended for use in roofing, mansard and fascia applications. Substrates may include 5/8″ (min.) plywood, nailboard insulation or equal with an underlayment of ice and water shield applied horizontally from eave to ridge. Other substrates may include metal decking or rigid insulation in conjunction with bearing plates. A minimum 2:12 pitch is recommended in most applications. Contact Petersen for assistance with details on projects requiring lower slopes. For coastal applications, aluminum panels along with stainless steel clips must be used for warranty. Consult a local architect/engineer for compliance with local codes and conditions.
Eave Notching
Factory-produced eave notching is available at nominal additional cost on Snap-Clad panels and Redi-Roof standing seam panels. Factory eave notching saves on labor cost by eliminating the need for field cutting to produce a properly trimmed eave detail.
