There are numerous panel configurations, thicknesses, coatings and detailing that are available for metal roofs. The most common for a non-residential project is a standing seam system, which, in general, involves a series of flat-surface metal sheets with vertical seams standing seams that allow the individual panels to be field connected to each other.
The configuration of these seams can vary, but the end result should always be a contiguous steel surface that is impervious to water intrusion. In addition, the fastening of these panels at the seams needs to be designed with continuous or individual clips that connect the metal panels to the structure below in a manner that satisfies the structural requirements discussed above.
The attachment of these clips should be performed under the surface of the metal roof and allow for necessary thermal movement of the roof panels. Only a panel system that has been tested in compliance with an ASTM E procedure, and one which can structurally resist the design loads developed using the ASCE 7 wind load production, should be specified.
Since the termination of the roof panels is the main location of roof leaks, they need to be specifically identified during the roof design process. There are two different basic designs, which are hydrokinetic and hydrostatic. Even though a minimum roof slope of between and is suggested by many manufacturers and associations, critical areas such as valleys, curbs and eaves are vulnerable and susceptible to water intrusion. This type of metal roof should only be specified when all of the specific conditions have been considered and allowing water under the steel surface in certain areas can be completely handled by underlayment and, therefore, is acceptable.
The basic principle for the seams, valleys and eaves associated with this type of system is to seal these areas permanently. Use either a sealant between metal members, secured by a weatherseal fastener or crimping the seam to permanently prevent any differential movement between metal surfaces involved. All thru-fasteners should be at non-moving locations and flashing locations where both flashing member components are allowed to move together.
Finally, the introduction of solid zinc or stainless steel fastener heads, powdercoated with paint to match the metal roof surface, plus weatherseal washers, which can be totally encapsulated within a concave washer attached to the fastener head, provides a practically non-visible attachment system.
Most architectural non-residential metal roofing systems will include a factory-applied paint. Use only a system which is comparable to a Kynar system, which will carry a minimum of a year total paint warranty.
With respect to weathertightness warranties, make sure that the duration of the warranty and the total manufacturer liability is identified in the specifications. Also, ensure that manufacturer inspections are required and the final warranty will not then exclude contractor workmanship. Manufacturer warranties should be necessary for a product to be included in a specification, but they should be inspected by the specifier to ensure that they are specific to a particular job and meet the requirements of the specifications.
