- 52. Other Panels Flush Wall and Soffit Panel • 1” Depth • Can be installed over plywood or open framing • 12” Panel Width • Optional Perforation Bermuda Horizon Panel • 1” or 1.5” Panel • Plywood • 12” Panel Width
- 53. Metal Tiles & Shingles • The shapes are infinite, combining roll forming and stamping techniques many profiles exist. Labor costs have to be considered, and gauges should be checked to make sure codes are met. • Metal tiles can be engineered to attain higher wind loads than their clay counterparts.
- 54. Pitch Limitations / Panel Lengths • Most metal roofing systems are designed to be used on pitches of 3/12 and greater. • If you have areas of your roof that are less than 3/12 either change the pitch, specify a flat roof material, or specify a low slope metal roof system (may add labor costs). • If your project has long rafter runs requiring long metal roofing panels spec a system with concealed fasteners that has allowance for panel movements. • If your project has many short panel lengths and intricate details don’t use a field seamed panel as installers will have to hand seam most of the job. Specify a snap-seam and consider aluminum.
- 55. FREQUENTLY ASKED QUESTIONS Last Section!
- 56. FAQ’s Frequently Asked Questions: Are metal roofs… • Noisy? • Attract Lightning? • More Costly? • Poor Insulators? • Poor performers in bad weather?

Notas do Editor
- At this point remind everyone to please fill out the Form B being circulated and to please print neatly!Ask that at the end of the seminar to please fill out the evaluation form and leave it with you.
- Metal lasts a long time!!!! Notre Dame
- Nonresidential metal roofing products have made substantial gains, particularly in the commercial and institutional segments. Metal roofing is continuing to gain share in the institutional segment (notably education and health care) despite funding issues. The metal industry has done a very good job of selling the value proposition for life cycle cost, energy efficiency, green building and durability – issues that matter to architects serving these segments.
- The combination of improving markets and improving share results in strong gains in tonnage shipped by the U.S. metals industry into these construction segments. Total tonnage shipped peaked at 2.2 million tons in 2008. The annual growth rate is forecast as 5% for 2012, accelerating to 8% by 2015. FMI anticipates that shipments will exceed 2.7 million tons in 2016. This will represent a total gain of 39% from 2011 and a gain of nearly 24% from the 2008 peak level.
- The survey was sent to 11,000 readers with 900 responses: The findings – 77% found are installing architectural standing seam metal roofing.72% found are installing architectural standing seam metal roofing for RE-ROOFING applications The Bottom Line: Shows that metal is a primer opportunity for new construction.
- Shows metal is a primary opportunity in the reroofing segment. Important since over 85% of the market is reroofing at this point.
- Metal Roofs reflect rather than absorb heat energy = less heat transfer into the building envelope. This is done through pigment technology

- This is the Largo Florida Public Library – also serves as a hurricane shelter for the community…this roof has been engineered to take on Cat 4 sustained winds.
- Continuous length – internal clips – less penetrations
- Lighting fixtures – gutters – appliances – ceiling grids – INTERNAL USAGE
- Exposed Fastener Panels – Pole Barns – Agricultural usage

- During the late 1800’s and early 1900’s the steel industry developed sheet goods which lead to the development of “corrugating” where they passed a thin sheet of metal beneath a corrugating drum and pressed undulations into the sheet. The undulations made the sheet stronger so that it could span structural members. This profile lead to other shapes, all having exposed fasteners. In this same category came 5V-Crimp,R-Panels,SM Rib,Etc. This direct method of fastening provides great wind resistance but does not provide for thermal movement. As panel lengths increased this created some problems.Limits expansion and contraction
- The steep slope metal roof sometimes called Hydrokinetic or Architectural relies on the pitch of the roof to shed water. The most common systems employ a snap-seam profile where one side of the panel has a male leg that inserts into the female leg on the other side of the panel and interlocks. These systems require no special seaming tools and therefore often save on installation costs. Architectural or low slope systems are normally installed over a solid substrate such as plywood which requires a moisture barrier between it and the metal such as asphalt saturated felt paper or a peel-and-stick membrane. The metal roof is the primary water barrier but the underlayment serves to direct off the roof any water that may get past the panel system, flashings and trims.
- Other Options include Batten Cap Systems or Nail strip applications as well.
