 === Mechanical Fasteners ===
-Mechanical fastening to steel decks provides more effective wind uplift resistance and greater horizontal shear resistance than adhesives (thereby decreasing potential membrane splitting).  Fastening patterns and rates that have proven to be successful are published in the '''''RoofStar Guarantee Standards''''' and should be enforced as a minimum. In addition to insufficient fasteners, the type of fastener can prove critical.  For example, failure may occur from nails with inadequate head size to pull through the roofing felts.

 === Wind Uplift ===
 ==== Design Wind Loads ====
-Design Wind Loads are forces caused by wind, which a structure is built to withstand, whether they are negative or positive forces. On the roof the forces are typically negative much like the negative pressure acting on the top of an airplane wing providing lift. Therefore wind acting against the wall of a building passes over the roof exerting uplift on the roofing system. Factors affecting uplift forces are wind speed, building height, roof slope, wall openings, roof overhangs and ground roughness. The roof is divided into three zones: the '''field'''; the '''perimeter''', and the '''corner'''.

 ==== Fastener Pull-out Strength ====

 ==== Deck Material ====
-Fastener requirements are not the same for all deck materials. As plywood thickness and steel gauge increases, fastener pull-out strength increases, hence fewer fasteners are required, as shown in the tables found in the '''''RoofStar Guarantee Standards''''' for [http://rpm.rcabc.org/index.php?title=Low_Slope_Membrane_Roofs '''Low Slope Roof Systems''']

 On steel decks, the initial use of bitumen as the adhesive has proven to be less successful than adhesion to concrete. Steel deck deflection can result in breaking the adhesive bond between the insulation and the deck. In addition, the use of bitumen may contribute to the fire hazards associated with steel decks.
