Vertical substrate must be clean and suitable for flashing.Alternate flashing substrates may be installed over existing vertical substrates if conditions prevent the substrate from meeting Custom Seal flashing requirements. Examples of alternate substrates are 1.3 cm (1/2") minimum thickness exterior grade plywood or 22ga G-90 Galvanized Steel. Securement must be achieved with corrosion resistant fasteners and be sufficent to resist 556 N (125 lbs) of pullout pressure per square foot. For compression details that utilize Custom Seal Waterstop, the substrate must be bared in the compression area down to either a masonry, or metal surface.

Molded EPDM Walkpad Installation

Walkpads are required at all permanent points of roof access and to and frompoints on the roof requiring once a month or more service. Molded walkpads will reduce wear on the roofing membrane but will do little to mitigate the effects of "heavy" traffic which could cause insulation damage if a suitable walk substrate is not designed to handle heavy traffic.

Paver Installation

Pavers must be set on a slipsheet of membrane or separator sheet in order to prevent abrasion damage to the roofing membrane

Vertically Mounted lightning rod -clean mounting area of membrane with TPO Cleaner,apply a generous bead of Custom Seal Waterstop to back of mounting plate in a pattern thatcrosses all holes in the plate, position plate in mounting location and secure to wall ensuring that the fasteners penetrate the bead of waterstop. Securment must be adequate to holdbracket firmly to substrate. Caulk the perimeter of the mounting plate with Custom Seal TerminationCaulk and fill in all exposed holes on mounting plate with Termination Caulk. Install the lightning protection grounding cable as detailed below in method #3.

Application of lightning protection on Mechanically Attached Systemsrequires the use of roof pavers to provide the lightning rods a stable surface to be mounted to. Use minimum 24" x 24" x 2" Pavers weighingno less than 40 pounds each laid in the pattern necessary on slip sheets of TPO membrane sized to extend 3" beyond paver in all directions and secured to the paver with a dollop of Termination Caulk. Care must be taken to run the pavers along the lines of membrane securement as this type of roof system will produce some amount of sheet flutter when subjected to significant wind loads. Install the lightning protection grounding cable between pavers as detailed below in method #3.

On Fully Adhered and Ballasted projects install a 6" strip of Reinforced TPO membrane by fully welding the membrane to the roof membrane along the path of lighting protection cable installation and mount the horizontally installed lightning rodsto that sacrificial layer of membrane by cleaning the membranestrip in the rod installation locations with TPO Cleaner, applyingCustom Seal Primer to the lightning rod mounting base location and allow to flash off, then apply a 4"x4" "puddle" of properly mixedPourable Sealer to the primed area of membrane and then set the perforated base into the puddle before the Pourable Sealer sets up. Once the Pourable Sealer sets up its safe to install the grounding cable. Grounding cable must be secured 36" o.c. tothe strip of reinforced membrane with 1½" x 6" strips of ReinforcedTPO Membrane hot air welded to the strip of membrane.

Night Seal Installation Instructions - For Use At The End Of The Work Day And As Required By Inclement Weather:

Extend the deck membrane 12" past the edge of the new insulation.Clean the substrate at the nite seal location to remove any dirt and debris. The seal you achieve can only be as good as your cleaning.Apply Custom Seal Primer to the last 2" of the top of the deck sheet and the last 5" of the bottom of the deck sheet and allow to flash off.Set the last 5" of deck membrane into a 5" wide bead of PourableSealer. The membrane should be 1" back from the edge of the Pourable Sealer in order to allow for the membrane edge to beenveloped into the sealer.Install a 2"x4" 1" back from the membrane edge and secure to the deck 24" o.c. to compress the membrane into the Pourable Sealer.Trowel Pourable Sealer over the exposed 1" of membrane to envelope membrane edge.Upon return to work remove the 2"x4" and cut the last 6" off the decksheet and discard. Then proceed with roofing operations.

Perimeter Securement LayoutFor Std. Warranty 50' High or Less

Detail #: 42.04-109/02

All Custom Seal TPO Mechanically Attached Systemsrequire half sheet perimeter securement. A half sheet width of up to 60% of the width of the field panels may be used. Half sheet securement is equal to the membrane securement used in the field of the roof. See the Mechanically Attached TPO Code Matrix for fastener and spacing requirements. If the project must meet Factory Mutual criteria refer to detail 42.04-3 and contact Factory Mutual for review.

Half sheets are required at all exterior edges of theroof system and at the upper level edges of transitions in surface height greater than 3'

If the building being roofed has any of the following conditions contact Custom Seal for assistance in determining half sheet requirements: A) Large wall openings totalling 10% or more of any wall area.B) Canopies open below the roof deck.C) In the immediate vicinity of large bodies of water or coastline.D) Building height in excess of 75'.

For projects requiring a warranty wind speed in excess of 54mph contact Custom Seal for perimeter securement requirements - additional half sheets and / or fasteners and seam plates may be required.

Perimeter Securement LayoutFor Factory Mutual Rated Systems

Detail #: 42.04-309/02

The width of the enhanced perimeter and corner securement areas on a Mechanically attached TPO roof system is determined by multiplying the building height by .4 or the lesser building dimensionby .1 whichever is less. The perimeter areamust be roofed with half sheets (half sheets up to 60% of the field sheet width are acceptable) secured at the same rate as thefull width field sheets of membrane. The corner areas must be further enhanced as shown by criss crossing the half sheets in the corners.Caution: When installing to Factory Mutualrequirements all fasteners used to enhance the corner areas must penetrate the uppermostlayer seam assembly.

As an option, corner enhancement may be accomplished by installing additional rows of securment through the half sheets and then striping in those rows of securement with either TPO flashing or TPO Cover Tape installed to Custom Seal specification.
