Tite-Loc

Tite-Loc is a PAC-CLAD standing seam roof panel from Petersen. The seam is closed in the field with a 90-degree mechanical lock, and concealed floating clips hold the panel to the roof. It is listed for commercial roofing and is written as an architectural standing seam roof system under Section 07410, Preformed Metal Standing Seam Roofing.

Tite-Loc and Tite-Loc Plus share the same dimensions. The difference is the seam closure, 90 degrees for Tite-Loc and 180 degrees for Tite-Loc Plus.

Seam height is 2 inches. Nominal widths are 12, 16 and 18 inches on center, and the listed minimum slope is 1/2:12. Panels are smooth as standard. Striations, pencil ribs, and striations with pencil ribs are available by request. Not every panel condition is stocked at each Petersen branch.

Maximum factory-produced panel length is 64 feet. Seams carry factory-supplied hot melt mastic, and panels are roll formed continuously with no end laps.

Four base materials are listed: 24 gauge steel, 22 gauge steel, .032 aluminum and .040 aluminum, with Galvalume Plus available. Aluminum is 3105-H14 to ASTM B209. Steel is 24 gauge G-90 galvanized or 22 gauge Galvalume.

The finish is Kynar 500 or Hylar 5000 fluorocarbon to AAMA 621, with 0.70 to 0.90 mil on the top side over a 0.25 to 0.3 mil prime coat. Total dry film thickness is 0.95 to 1.25 mil, and the bottom side has a 0.25 mil primer. The finish warranty is 35 years, non-prorated.

• UL 580 Class 90 wind uplift, rated up to 18 inch on center.
• UL 1897 wind uplift.
• UL 790, rated Class A for fire.
• UL 263, fire resistance rated.
• UL 2218, impact resistance rated.

The 24 gauge and 22 gauge steel and the .032 and .040 aluminum panels are UL-90 classified over a solid substrate. ASTM tests are E1592, E331/1646 and E283/1680. The SSTD missile impact line on the sheet is marked as applying to Tite-Loc Plus only.

A weathertightness warranty is available, with a period of 20 years from substantial completion. The written finish warranty is 30 years from substantial completion for color fading beyond 5 Hunter units under ASTM D2244, chalking beyond a No. 8 rating under ASTM D4214, and cracking, checking or peeling of the coating. A two-year applicator warranty covers repairs needed to keep the roof and flashings watertight.

Panels are attached by concealed fastener clips in the side laps, spaced to carry positive and negative design loads while allowing thermal movement. Substrates named are plywood, ISO, nailbase and roofing underlayment, with a 40 mil minimum high-temperature peel and stick membrane required, as outlined by the panel manufacturer. Underlayment laps 12 inches over hips and ridges and 6 inches over the metal of valleys and built-in gutters, as required for the 20 year weathertightness warranty.

Trim is made of the panel material and finish, press broken in 10 to 12 foot lengths and overlapped when erected, with factory-welded miters. Closures at the top of each elevation are composition or metal profiled closures matching the face sheet.

Minimum panel length is 4 ft, and the Annapolis Junction, Maryland facility minimum is 60 in. Panels are leveled for flatness, and a factory-applied sealant bead is optional. Pencil ribs are available by request only.

Panels can be curved in the field or at the factory, depending on radius and length, to a minimum radius of 20 ft. A mechanical seamer is required. On slopes greater than 6:12, seamer slippage can scratch the finish and may void the warranty. D.I. Roof Seamers is the only supplier of seaming equipment approved by Petersen.

Substrates are 5/8 in minimum plywood or nailboard insulation, with ice and water shield applied horizontally from eave to ridge, or metal decking, purlins or rigid insulation with bearing plates. In coastal applications, aluminum panels with stainless steel clips are required for the finish warranty. A 35-year non-prorated finish warranty can also cover trim.
