1. A method for forming an adhered membrane roof system that meets FM 4474 standards for wind uplift, the method comprising:
(i) applying a bond adhesive to a substrate on a roof to form an adhesive layer having a thickness of at least 5 mils and less than 30 mils, where the bond adhesive includes a silyl-terminated polymer and a hydrocarbon tackifier resin, and is devoid of phenolic resin; and
(ii) applying a membrane directly to the adhesive layer, whereby a bond is formed between the substrate and the membrane that exceeds 1 pli, when measured according to ASTM D1876.
