Storage/cold TapcoSlates should not be stored on roof decks in such a manner as to over-stress and/or damage the deck and supporting structure.
Cold Weather Installation: TapcoSlates should be stored in original packaging in a storage facility where the temperature meets or exceeds 7°C. Use protective coverage over all pallets while being temporarily stored on-site. TapcoSlates must be conditioned at a temperature no lower than 7°C for twenty-four (24) hours prior to use. TapcoSlate may be installed at temperatures as low as 0°C but must be hand fastened, the use of a pneumatic gun below 7°C will result in cracking and webbing in the fastened area. Be sure to follow the manufacturer’s installation requirements for all underlay or membrane and any other applications. Comply with any and all local building regulations. Note of Caution: The slates can be slippery under certain conditions and job site safety procedures should be enforced.
