7 System Table Wall/Curb Flashing Materials And Requirements Table Firestone Warranty Summary Firestone Building Products UltraPly TPO Design Guide Interim Updates at: 3/26/2013 5 GENERAL Design CRITERIA A. APPLICABILITY: 1. Parameters of this manual outline the minimum requirements for ReflexEON and UltraPly TPO Firestone Warranty. Local code and insurance requirements may require specific enhancements. 2. Warranties beyond 10 and up to 25-years may have specific system enhancements, some of which can be found in this manual. Contact the Roof System Solutions Group at Firestone Building Products for additional information. 3. For 30-year warranties, see the ReflexEON Platinum and UltraPly Platinum .080 membrane information. 4. For any warrantable 20 year UltraPly TPO roof system, the UltraBlend system is an option for wall flashings and details.

8 5. Statements in this Design Guide are provided in good faith with the expectation that a Design professional be consulted prior to any job decisions being made. 6. Firestone roof systems may or may not be applicable, without special consideration, if subject to local, regional, or national building code requirements or testing agency restrictions. a) It is the building owner s or the Design professional s responsibility to consult with the controlling code agency official(s) to determine the specific requirements of each project and each system. a) The local Firestone Roof Systems Advisor should be contacted when local codes are in conflict with Firestone recommendations. Contacts: 7. The following conditions require special consideration and may not be warrantable.

9 Contact the Roof System Solutions Group at Firestone Building Products if any of the following conditions are present: Roofs that exceed the maximum slope and height limits for the particular roof system assembly, see table Projects that require special wind coverage, greater than 55 mph Roofs located where localized wind phenomenon may occur, reference ASCE-7 wind maps Roofs located in downslope, foothills of mountain ranges or escarpments Mechanically attached systems located within 5 miles ( Km) of the ocean coastline or within 1,500 feet (457 m) of a Great Lake shoreline Geographical areas susceptible to hurricanes Roofs subject to chemical or process byproduct discharge Roofs with non-linear slopes such as arches, domes and barrels, etc Buildings with large openings in a wall (greater than 10% of the any one wall surface)

10 That could be left open in a storm Roofs subject to heavy or repeated traffic in an area Roofs subject to positive pressure situations such as: pressurized buildings, air infiltrating decks, canopies, overhangs, airplane hangars, distribution centers, etc Buildings with high interior humidity such as swimming pools Roof decks that do not provide adequate fastener pullout resistance 8. Cold storage, freezer facilities and swimming pools constitute a special condition. A designer familiar with cold storage, indoor swimming pool construction and vapor migration should be consulted in the Design of the roof system and its integration with the rest of the structure envelope. Certain situations may arise where Firestone specifications and/or roofing requirements cannot be applied.
