S. All lumber in contact with masonry or concrete is to be pressure treated except for plywood, U.O.N. T. The wood blocking shown in the details and sections are graphic representations only. Solid continuous blocking shall be provided to match roof insulation at the thickest point and maintain the same elevation for the entire perimeter of the roof unless otherwise indicated. U. Do not install wood nailers ahead of new roofing work. Only install nailers that can be covered the same day. V. Counter sink all fasteners for wood blocking. W. All existing wood blocking to remain is to be fastened with additional screws as per FM 1-49 placement. Pre-drill and set new securement using epoxy shields in masonry units and TEK fasteners in steel as required for positive attachment. Consult with professional fastener companies like Hilti, Triangle fasteners, etc. for additional guidance. X. All roof curbs greater than 24"wide and set perpendicular to the roof slope shall be required to receive a tapered saddle to promote positive water flow. Y. The new roof system is to incorporate insulation attachment to incorporate wind pressure enhancements at the field, perimeter, and corners in accordance with ASCE 7 as defined by local codes. Z. Premanufactured tapered insulation units are to be used at roof sumps, crickets, and saddles to promote positive water flow to the roof drains. Field-fabricated tapered units may be used if approved during the submittal process. AA. All roof membrane details are to follow roof manufacturer's details for a 30-year warranty whether or not a 30-year warranty is required. BB. Install manufacturers pre-fabricated inside and outside flashing corners following the recommendations and requirements of the roofing membrane manufacturer. Provide "t-joint covers" at the base of all vertical flashing /field seam intersections. CC. Secure top edge or termination of all membrane flashing using an aluminum termination bar secured 12-inches o.c., max. (detail shown on the project plans), and within 2-inches of each end. Prior to termination bar installation, install manufacturers recommended compression sealant behind flashing where termination bar will be placed. Apply manufacturers' approved sealant to the top edge of flashing and termination bar after proper mechanical attachment. DD. Extend all new membrane flashing up and over perimeter parapet wall under metal edge cleat to cover beyond the exterior of the wood nailer/ parapet transition by 1 '/2" minimum. EE. Extend all new membrane flashing under roof metal edge to cover beyond the exterior of the wood nailer/parapet transition by 1 '/2" minimum. FF. Provide walkpads at the base and top of ladders, stairs, at roof access doors, at other roof access points, and at all serviceable mechanical unit doors or access panels. GG. The use of"penetration pans" or"pitch pockets" is not permitted unless the geometry of multiple penetrations is not sufficient for field wrapping and without prior owner approval. HH. All roof deck penetrations and perimeter edges of the roof section will be required to receive a reinforced fire-stop sealant to prevent air and moisture drive into the new roof system. II. All wood supports for electrical conduit and gas line supports must be replaced with new Caddy, Miro, or equal premanufactured units to accommodate the new roof system. JJ. All perimeter edge metal profiles must meet ANSI/SPRI ES-1 wind design requirements for FM Global and included in the membrane manufacturer's warranty for the minimum of 30 years including wind and performance. KK. All new metal flashings for RTU counterflashing, cool stack base flashings, rain hoods, miscellaneous vertical wall flashing terminations, perimeter wall counterflashing, reglet metal, SEA00511 / Prologis - SEA00511 01 1000 - 5 Summary - FY24- Everett 1 - Capital Roofing Project
