Loadmaster Roof Decks: Proven Performance, Extended Roof Life & Industry-Leading Warranties

55+ Years of Proven Roof Life Extension

Loadmaster Roof Decks have a 55-year track record of significantly extending the service life of both built-up and modified bitumen roof membranes. Independent surveys of roof systems installed over Loadmaster decks confirm active service lives ranging from 30 to 53 years — far beyond standard industry expectations.

Our benchmark performance speaks for itself: A 3-ply, 15 lb. asphalt felt roof with a gravel surface — originally rated for 15 years — has been in service for 36 years over a Loadmaster Roof Deck. That's 21 additional years of service life, a 140% life extension beyond its original design rating.

Modified bitumen membranes installed on Loadmaster Roof Decks 30 years ago are still performing reliably today, with many years of additional service life anticipated.
