What’s SPRI working on?

Current Technical Task Force Initiatives

The SPRI Technical Committee works on projects initiated by SPRI members, which are of interest to the commercial roofing industry. Each project approved by the SPRI Board of Directors is completed by a Task Force of SPRI members working together. SPRI Task Forces change as project objectives are achieved and new projects are initiated. Consider joining SPRI to add your voice to the conversation, and to start new conversations.

Air Barriers

– Al Janni, Duro-Last

The Air Barriers Task Force is working with the Air Barrier Association to create a set of air barrier detail drawings

Air Intrusion

– Al Janni, Duro-Last

The Air Intrusion Task Force objective will be to investigate the impact of air diffusion on energy use in roofing systems. The Task Force will provide credible data to the ASHRAE Air Intrusion working group and collect data and reports from the NRC air intrusion study and the SIGDERS field data as well as from the ORNL research and reports.

Code Development Task Force

Mike Ennis, SPRI

The objective of the Code Development Task Force is to develop and advocate for safe, technically correct, and easily enforced code language while also promoting the goals of the SPRI’s membership

Codes & Standards

– Mike Ennis, SPRI

The objectives of the Codes & Standards Task Force are to provide timely and pertinent information on Codes & Standards that may affect the sale and use of sheet membrane roofing systems and the components used in those systems. The Task Force will respond promptly to issues relating to Codes and Standards based on the consensus of the SPRI membership. As of January 2014, the Cool Roof Codes update will be provided in the Codes & Standards meeting.

Code Compliance Interface

– Eric Younkin,Soprema, Luis Cadena, NEMO

SPRI is working to create an industry coalition to identify common challenges in receiving Miami Dade approvals and to create a platform for sharing those challenges with Miami Dade representatives with the end result being mutually acceptable solutions.

D6878 TPO Consideration for Revision

Eric Olson, Johns Manville

The objectives of the Task is to investigate whether there are performance benefits realized with a fleece back Thermoplastic Polyolefin( TPO) membrane versus smooth back; physical performance and potential impact resistance. The D6878 standard currently combines these products under one membrane type. All discussion and activity of this Task Force will focus on potential updates to the ASTM standard D6878.

ES-1/ED-1 Standard Development

Bob LeClare, ATAS International, Inc.

This Task Force will revise the current ANSI/SPRI/FM ES-1 standard into two separate documents: a design document and a test standard. The two documents will be canvassed for acceptance as American National Standards. The test standard was completed in 2016. The design standard is currently being canvassed for approval as an American National Standard.

Impact of Wind Loads on Flexible Roof Systems

Mike Ennis, SPRI

This Task Force will work with the Institute for Business and Home Safety (IBHS) and other industry representatives to determine cost to develop a test plan to evaluate the impact of wind loads on flexible roof systems. The Task Force will then determine the next steps for the project.

MCA Standard Development

– Bob LeClare, ATAS International

This Task Force, comprised of SPRI  and the Metal Construction Association (MCA) Members will prepare and canvass the MCA document, Test Method for Structural Performance of Flashings Used with Metal Roof Systems, for approval as an ANSI standard.

Product Category Rules

– Katie Chapman, Duro-Last, Inc.

The SPRI Product Category Rules are scheduled for renewal. This Task Force will review, updated and complete the renewal process.

RP-4 Recanvass

– Todd Taykowski, Firstone Building Products

The ANSI/SPRI RP-4 Standard, Wind Design Standard for Ballasted Single Ply Roofing Systems, will be reviewed, edited if necessary, and canvassed for re-approval as an American National Standard. This review is required every 5 years per ANSI Essential Requirements.


–Zebonie Sukle, Johns Manville

This Task Force will engage with the SCAQMD to discuss the proposed revisions to allowable VOCs and to provide industry feedback on the impact and timing of these revisions.

WD-1 Recanvass

– Joe Malpezzi, Carlisle Construction Materials

The ANSI/SPRI WD-1 Standard, Wind Design Standard Practice for Roofing Assemblies, will be reviewed, edited if necessary, and canvassed for re-approval as an American National Standard. This review is required every 5 years per ANSI Essential Requirements.

Wetting Curves: Acceptable roof material performance
at elevated moisture content

David Hawn, Dedicated Roof & Hydro-Solutions

This Task Force will update the information pertaining to the acceptable level of moisture content discovered by field testing. Equilibrium moisture content will be established for at least two temperature and humidity conditions resulting in resource data the can be interpolated or extrapolated to use with field data. Likewise, for R-value loss at moisture content levels within substrate materials (TRR-80 wetting curves) updated and improved resource information is necessary. A third indication of acceptable substrate materials at known moisture content levels is the strength of the material as it would relate to fastener pull through, or, for adhered systems, pull off strength reduction. The Task Force may determine other indicators as well.

The materials that will be included are insulation, cover boards, deck material, and insulating /Cellular Concrete products, to name a few.
