Tite-Loc panels deliver a balance of structural strength and architectural appeal, featuring exceptional flatness and optional enhanced weather resistance. Offered in lengths ranging from 4 to 64 feet, they include a 2-inch leg height for mechanical seaming. Designed for use over a variety of substrates, these panels require a minimum roof pitch of 1/2:12. Available in both steel and aluminum, Tite-Loc panels can also be curved to meet specialized design needs.
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 35-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
Tite-Loc Plus panels are intended for use in architectural and structural roofing. 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, purlins or rigid insulation in conjunction with bearing plates. A minimum 1/2:12 pitch is required. Contact Petersen for further assistance with projects details.
Snap-on standing seam
Designed with concealed fastener systems and optional curved profiles, these panels deliver reliable structural performance for a wide range of applications—from architectural to industrial roofing. Available in both steel and aluminum, they are compatible with multiple substrates, roof slopes, and a broad selection of color finishes.
