The manufacturer s published installation instructions must be available at all times on the jobsite during installation. RESISTO self-adhering roofing membranes are components of roof covering systems that may be installed over new roofs as described in Table 1 and Table 2. The roof slope must be a minimum of 1 / 4:12 (2 percent slope) and must not be more than maximum slope for the particular system as specified in Table 1. 4.2 Fire Classification: Roof covering systems described in Table 1, when installed in accordance with this report, are classified as Class A or C roof covering systems in accordance with UL790 or ASTM E108. 4.3 Wind Resistance: The RESISTO self-adhering membrane roof covering systems described in this report have a maximum allowable wind uplift capacity as noted in Table 2. Metal edge securement systems must be listed in accordance with 2011 ANSI/SPRI/FM4435 ES-1 and designed and installed for wind loads in accordance with IBC Section 1504.5 and IBC Chapter 16. 4.4 Reroofing: Prior to installation of new roof coverings, inspection in accordance with IBC Section 1511, IRC Section R907 and approval from the code official having jurisdiction, is required. Class A or C roof covering systems may be installed over existing roof coverings without additional roof classification tests, provided the resulting classification is the lower of the new and existing roofing classifications under the following conditions: New uninsulated systems installed only over existing uninsulated systems New insulated systems installed over existing uninsulated systems only 5.0 CONDITIONS OF USE RESISTO Self-Adhering Modified Bitumen Roofing System described in this report complies with, or is a suitable alternative to what is specified in, those codes listed in Section 1.0 of this report, subject to the following conditions: 5.1 Installation and application of the RESISTO modified bitumen roofing membranes must comply with the IBC, the manufacturer s published installation instructions, and this report. The instructions within this report govern if there are any conflicts between the manufacturer s installation instructions and this report. 5.2 RESISTO modified bitumen roofing membranes must be installed by professional roofing contractors trained and approved by the manufacturer. 5.3 Any foam plastic insulation, where used, must bear the label of an approved agency indicating that the foam plastic has a flame-spread index of not more than 75 when tested at the maximum thickness intended for use in accordance with ASTM E84 (UL 723), subject to the approval of the code official. 5.4 Above deck thermal insulation board must comply with the applicable standards listed in IBC Table 1508.2 or IRC Table R906.2. 5.5 Design wind uplift pressure on any roof area, including edge and corner zones, must not exceed the allowable wind uplift pressure listed for the system installed in that particular area. Refer to allowable wind uplift pressure for systems as listed in Table 2. 5.6 The allowable wind uplift pressures listed in Table 2 are for the roof covering only. The deck and framing to which the system is must be designated for the applicable components and cladding wind loads in accordance with the IBC. 5.7 Calculations demonstrating that the required wind resistance is less than the allowable wind resistance must be submitted to the code official for approval. 5.8 Where gypsum board is used as barrier board in the roofing assembly, weather protection must be provided to prevent damage to the gypsum board prior to application of the roofing membrane. 5.9 The membranes are manufactured in Drummondville, Canada and Wadsworth, Ohio under quality-control programs with inspections by ICC-ES. 6.0 EVIDENCE SUBMITTED Data in accordance with ICC-ES Acceptance Criteria for Membrane Roof Covering Systems (AC75), dated July 2010 (editorially revised September 2016). 7.0 IDENTIFICATION Each roll of, and SA Smooth Ply 40 is labeled with the company name (RESISTO) and address, product name, date code and the evaluation report number (ESR-3909).
