Minimum pitch of 5V metal roofing

Minimum pitch of 5V metal roofing

Minimum pitch of 5V metal roofing

(OP)
Hi guys,
I have had a few files recently where I have been asked to comment on roof-over projects that were leaking or otherwise unsatisfactory. In the cases I am thinking of 5V metal roofing was used on a low-slope roof (about 1:12 or less). The specs for metal roofing that I have seen require a minimum pitch of 3:12. Does anybody know any background on this number and if there are any studies on the performance of metal roofing at lower slopes? I am thinking that there may be special lap or gasket requirements.
TIA.

RE: Minimum pitch of 5V metal roofing

I think it has to do with the spanning strength of the metal roofing. With a flatter roof, you have more potential for snow/ice buildup, thus need a stronger panel. 5V is relatively low profile, with large flat areas between the ribs, so is relatively weak. Other types of metal roof are suitable at flatter pitches.

Typical Minimum Slope is: 3:12

White Paper - The Criticality of the E/E Architecture
Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
White Paper - Model Based Engineering for Wire Harness Manufacturing
Modern cars, trucks, and other vehicles feature an ever-increasing number of sophisticated electrical and electronic features, placing a larger burden on the wiring harness that enables these new features. As complexity rises, current harness manufacturing methods are struggling to keep pace due to manual data exchanges and the inability to capture tribal knowledge. A model-based wire harness manufacturing engineering flow automates data exchange and captures tribal knowledge through design rules to help harness manufacturers improve harness quality and boost efficiency.

White Paper - Modeling and Optimizing Wire Harness Costs for Variation Complexity
This paper will focus on the quantification of the complexity related costs in harness variations in order to model them, allowing automated algorithms to optimize for these costs. A number of real world examples will be provided as well. Since no two businesses are alike, it is the aim of this paper to provide the foundational knowledge and methodology so the reader can assess their own business to model how variation complexity costs affect their business.
