Notice · This guide contains general design guidance and suggested application instructions and details for proper application of Best Buy Metals (BBM) metal roofing products. It is the responsibility of the installer to verify conformance of installation to applicable building code, safety, and insurance requirements. BBM assumes no responsibility for any problems which might arise as a result of improper installation or any personal injury or property damage that may occur with the product’s use. · Statements in this guide are provided in good faith with the expectation that a design professional be consulted prior to any job decisions being made. Projects should be engineered to conform to applicable building codes, regulations, and accepted industry practices. · Installing a metal roofing system is a skilled craft that requires considerable trade knowledge and experience. It is not the intent of this guide or BBM to train individuals in the skills required to properly install a metal roof system or to convey all the necessary trade or general construction knowledge required to properly and safely perform work on a roof. BBM does not guarantee and is not liable for the qualifications of the installer. ○ For additional information and resources pertaining to the installation of metal roofing materials, the following sources are recommended: a. SMACNA (Sheet Metal and Air Conditioning Contractors’ National Association) Architectural Sheet Metal Manual. (www.smacna.org) b. The NRCA (National Roofing Contractors Association) Roofing Manual: Metal Panel and SPF Roof Systems. (www.nrca.net) · It is the responsibility of the BBM customer, installer, and/or designer to ensure that the details meet particular building requirements to assure weathertightness. · This guide is intended to be used in conjunction with engineered shop drawings specific to an individual project (if applicable). Custom roof conditions and detailing are covered by engineered shop drawings for the specific project. In the event of a conflict between this guide and the engineered shop drawings, the engineered shop drawings will take precedence. · Contents in this guide are subject to change and revision without notice. Please contact BBM to verify that this manual is the most current copy available. b. Applicability · The metal roof system as described within this manual is classified as a standing seam metal roof panel. Panels are mechanically attached with hidden fasteners to a continuous solid substrate with an underlayment. The detailing and attachment methods described within this manual best reflect “steep sloped” sheet metal joinery considered a craft or trade. This type of detailing, with clean lines and hidden fasteners is desired for high performance in combination with visual appeal. c. Safety · There are potential hazards associated with the installation of a metal roof system. An experienced installer should recognize these hazards, be qualified to work with them, and be capable of providing safe work practices and equipment that minimize the risks of injury. Following are some warnings that should be considered when working with metal roofing. These may not cover all hazards, so the installer should take proper precaution to be prepared for working on roofs and handling metal. ○ OSHA (Occupational Safety and Health Administration): Obey OSHA regulations, particularly those related to roof construction, such as Title 29 Code of Federal, 1926 Subpart M, Fall Protection. For copies of OSHA regulations visit www.osha.gov . ○ Use fall protection and all appropriate safety equipment as agencies or jobsites require. ○ Avoid working on surfaces that are covered with moisture, frost, snow/ice, dust or other substance that may cause unsure footing. ○ Never walk on substrate, underlayment, or panels that are not properly secured in place.
