Why Nailers are important for Low Slope Roofing

ANSI SPRI ES1 has been in operation since 2003 to assist builders, suppliers, owners and contractors in avoiding perimeter edge metal assemblies failing in low slope roofing systems. Edge metal is also the primary form of membrane securing, a noticeable indicator of performance or failure, and is needed in a high wind event to withstand the main effect on the roof. What are we doing to ensure that these checked and code-compliant assemblies move load to other reliable and viable components which will at least withstand the transfer of load?
The dominant alternative in commercial building perimeter joinery tends to be nailers made from wood.

This is largely attributed to initial prices, affordability and best procedure. There are various concerns when we start determining how best to secure a facility’s perimeter. Is the architecture wary of condensation and water infiltration for fog, mold and rot? Can the selected part Warp build unstable and fragile link points over time? Would the sort of fastener used react with the substrate which causes rust or decay? The labor required to build the nailer is economically feasible with radius, convex / concave, or a high nailer state of construction. With current code insulation criteria, it is not unusual to see tapered isolation at the periphery in roof assemblies with nailer constructions that reach 12 “in height. Many of these issues fall back to the designer to answer, and it may be useful for designers to provide wind uplift and connection reference tools as well as appropriate plans in their construction for fitting in thermal, climate, and vapor barriers.

The good news is that in commercial buildings, there are numerous services that discuss the nailers and their significance. These specifications are intended to provide a baseline guide to specifiers and installers to reduce the incidence of a secret vulnerability at the perimeter of the roof assembly.

If we continue to search for clarity in load transfer, insulation stability, and proper roof-to-wall change, don’t forget your nailer ‘s secret detail, and the reliability and significance of this essential detail.
