| Notice to Reader | |
| Images used in a Construction Detail are representative and not intended in their representation of an assembly to be prescriptive. Nor are they necessarily drawn to scale. Rather, they are provided to visually convey the Standards, Guiding Principles and Recommendations of the RoofStar Guarantee Standards for a Waterproofing or Water-shedding System. Actual design with respect to dimensions, the selection of materials and their application remains the responsibility of the Design Authority. The full text of applicable RoofStar Guarantee Standards may be read by using the blue hyperlinks | |

1 WORK INCLUDED
- (1) Membranes
- Membranes must be installed to RoofStar Guarantee Standards and the manufacturer's printed instructions (NOTE: Fasteners shall be installed 4” or more above the maximum water line, and gutters must include a scupper overflow drain.). Also refer to 12.2 Built-in Gutters in the RoofStar Guarantee Standards for Architectural Sheet Metal (ASM) Systems.
- (2) Adhesion
- Membranes must be fully adhered, where exposed, and mechanically fastened at terminations 300 mm (12") o/c
- (3) Height
- The minimum vertical sealed height above the maximum water level is 150 mm (6"). The membrane run up the slope will vary with roof pitch. Increase height in heavy snow regions. Built-in gutter membranes can be extended to act as Ice and Water Protection. Underlay or eave protection membrane must overlap built-in gutter membrane by a minimum of 200 mm (8") and be installed in shingle fashion (not shown for clarity).
- (4) Metal cap flashing
2 RELATED WORK BY OTHERS
- (A) Acceptable Deck

- Dimensions of parapets, cants and water loading of gutters are variable and should be determined by design authority
NOTE: Refer to RoofStar Guarantee Standards for additional requirements.
