Consult with manufacturers early in design stage to obtain current manuals, specific guidance, and structural information regarding roof attachment. Early contact
18、 will reduce need for corrections and changes during review process and construction phase. Ensure that system detailed and specified can be provided by three separate manufacturers.2. Calculate wind uplift forces in accordance with UFC 1-200-01, “General Building Requirements“. Submit calculations
19、and stress diagram with design review package.3. NAVFAC minimum guidelines are one in 24 one-half inch per foot for roof slopes. Provide greater slope if possible. In renovation of existing buildings, adequate slope must often be obtained by imaginative solutions. Prefabricated steel systems, sleepe
20、rs, and stub walls have been used successfully, but attachment and structural stability of these must be assured. In some existing structures it will be difficult to design strong connections to structural system unless modifications are made to resist wind forces SECTION 07 61 14.00 20 Page 4Provid

High winds and thermal movement create stresses in flashing which must be resisted by careful detailing o
22、f attachment.While standing seam roofing presents continuous, sealed surface to the elements, flashing transitions are often the cause of serious problems. Overhangs are especially susceptible to high wind forces, and attachment at the edges should be carefully designed. Copious use of sealants and
23、closure pieces molded to conform to the roof panels is imperative.5. Building may require equipment such as antennae, ladders or lightning rods installed on roof. Access to roof-mounted mechanical equipment is often required. Provide walking surfaces and attachment accessories which do not compromis
24、e integrity of roof system. These accessories should provide support without penetrating roofing panels. Usually this is done with clamps attached to standing seam, or specially designed clips. Provide curbs or structural supports for mechanical equipment. Where condensate or other piping will be at
25、tached to or come in contact with roofing panels, ensure that the piping and anchorage materials are compatible with roof panel base metal to avoid corrosion from galvanic action. Ensure that condensate or other discharge of liquid onto roof panels will not stain or corrode panel finish and/or base
