LUCIE COUNTY BUILDING DIVI REVIEWED FOR COMPLIANCE o Whom It May Concern: REVIEW BY DATE R PLANS ANb PE I' MUST BE KEPTO JOB SITE OR NO INSPECTIONS) WILL BE MADE Ps outlined in the Florida Building Code, Extreme Metal Fabricators, LLC will accept the installation of metal roofing panels over one layer of asphaltic shingles or modified bituminous roofing, assuming all requirements of the 2017 Florida Building Code Sixth Edition, all of Chapter 15, specifically Section1511 Existing Roofing, and/or 2017 Florida Building Code- Residential Sixth Edition, all of Chapter 9, specfcally Section 905.10 and Rerootina Section 908 have been met. It is important to ensure the existing substrate is not deteriorated, there is no entrapped moisture, meets all code requirements, and to install an approved separator underlayment between the existing roofing and the metal panels, such as those that comply with ASTM D226 Type I or Type II or ASTM D 1970, or ASTM D 4869. The roofing contractor of record must verify the aforementioned requirements. Having confirmed code requirements, installation in this manner is approved by Extreme Metal Fabricators, LLC as the manufacturer. Plywood sheathing must be minimum 15/32" CDX plywood or 3/4" wood plank, solid decking, fastened per FBC requirements. The wood substrate must be inspected.to ensure that it has not deteriorated and is acceptable as a suitable substrate for additional roofing, and is attached structurally per current codes. Fasteners used for metal roofing should penetrate minimum'/4" through structural decking or a .minimum of 1" penetration into a thicker wood substrate, to insure pull-out values remain the same. Consideration should be given to the unevenness of the underlying shingles, which may telegraph through the new metal panels. As in all metal roofing, "oil canning" is an inherent condition that can occur in the panels. Care should be taken during the installation, to observe the metal panels as they are installed, and adjust installation procedures, if possible, to help to minimize "oil canning". "Oil Canning" is an aesthetic issue not a structural issue, and not a cause for rejection. The energy savings that is normally observed after a new metal roof replaces the previously shingled roof, which has been documented to account for 20% - 29% savings, may be negated due to the underlying. shingles holding heat energy much longer than a metal panel installed without shingles beneath it. It is important to comply with all requirements of the Florida Building Code, Fire Rating requirements, and local code requirements. As always, authorities having jurisdiction, (building department) should be consulted, and approve your demolition and reroof installation methods, prior to beginning work. THESE PLANS AND ALL PROPOSED WORK ARE SUBJECT TO ANY CORRECTIONS REQUIRED BY FIELD INSPECTORS THAT COMPLY WITHSALLRAPPLICABLE CODES.
