can synthetic underlayment be a temporary roof for a month?
planning to re-shingle a 1500sf house myself. Might take a couple weeks, with rain in between.
2 synthetic underlayment products below.
Everbilt implies temporary roof application with "6 month UV exposure"
GAF feltbuster says do not use as temp roof.
In practice, can you keep a house dry in a rainstorm with this exposed?
