Attachment Methods

In Bid-Advantage the term "Attachment Method" simply refers to a system by which layers of underlayment and membrane are secured to the roof deck of the structure.

Attachment methods for roof systems in Bid-Advantage fall into one of two categories

Mechanical Systems
Mechanical is the de-facto attachment method for Duro-Last, Duro-Bond, Duro-Roof, and Duro-Tuff

Adhered Systems
Adhesive is the only attachment method for Duro-Fleece, however, Duro-Last and Duro-Tuff may also be fully adhered.
