E.
Where indicated, fabricate metal roof panel joints with factory-installed captive gaskets or separator strips that
provide a tight seal and prevent metal-to-metal contact, in a manner that will minimize noise from movements within
panel assembly.
F.
Sheet Metal Accessories: Fabricate flashing and trim to comply with recommendations in SMACNA’s
“Architectural Sheet Metal Manual” that apply to the design, dimensions, metal, and other characteristics of item
indicated.
1. Form exposed sheet metal accessories that are without excessive oil canning, buckling, and tool marks and that
are true to line and levels indicated, with exposed edges folded back to form hems.
2. Seams for Aluminum: Fabricate non-moving seams with flat-lock seams. Form seams and seal with epoxy
seam sealer. Rivet joints for additional strength.
3. Seams for Other Than Aluminum: Fabricate non-moving seams in accessories with flat-lock seams. Tin edges
to be seamed, form seams, and solder.
4. Sealed Joints: Form non-expansion but moveable joints in metal to accommodated elastomeric sealant to
comply with SMACNA standards.
5. Conceal fasteners and expansion provisions wh ere possible. Exposed fasteners are not allowed on faces of
accessories exposed to view.
6. Fabricate cleats and attachment devices from same material as accessory being anchored or from compatible,
non-corrosive metal recommended by metal roof panel manufacturer.
a. Size: As recommended by SMACNA’s “Architectural Sheet Metal Manual” or metal roof panel

EXAMINATION
A.
Examine substrates, areas, and conditions, with Installer present, for compliance with requirements or installation
tolerance, metal roof panel supports, and other conditions affecting performance of work.
1. Examine primary and secondary roof framing to verify that rafters, trusses, angles, channels, and other
structural panel support members and anchorages have been installed within alignment tolerances required by
metal roof panel manufacturer.
2. Examine solid roof sheathing to verify that sheathing joints are supported by framing or blocking and that
installation is within flatness tolerances required by metal roof panel manufacturer.
3. For the record, prepare written report, endorsed by Installer, listing condition detrimental to performance of
work.
B. Examine roughing-in for components and systems penetrating metal roof panels to verify actual locations of penetrations
relative to seam locations of metal roof panels before metal roof panel installation.
C. Proceed with installation only after unsatisfactory conditions have been corrected.
D. All work shall be installed in accordance with the approved shop details under direct supervision of an experienced sheet
metal craftsman. Attachments and joints shall allow for expansion and contraction from temperature changes without
distortion or elongation of fastener holes. Flashing shall be installed in strict accordance with the recommended practice
in the AA, NRCA, and SMACNA architectural sheet metal manuals: without fasteners in end laps and isolated from
dissimilar materials.
