For slate tile or other roofing applications Contact VaproShield for review and approval. 

SlopeShield is not to be used as a temporary roof covering during the construction period. SlopeShield can sustain up to 4 months of UV exposure but is not intended to be the primary liquid water hold out barrier. Temporary protection measures such as tarps must be used when rain, snow/ice or storm events exist or are anticipated.
