I saw an ad for Mernard's today with different roof membranes on sale.
.045 EPDM rubber membrane in a 10'x100' roll is $469.
.045 White premium reinforced membrane PVC/TPO hybrid 10'x100' is $1089. (solvent weld)
.045 TPO 10'x100' is $519
APP Torch down is $59.97 per 100 square feet, so it would be $599.70 for 1000 s.f.
I think I can buy 6 mil poly locally in a 20'x100' roll for $79.
What is the advantages/disadvantages of each? Which would you recommend for a Wofati/Oehler house?
