SPRI Bulletin Addresses Code Evaluations for Roofing Products

Waltham, Mass.-based SPRI’s latest informational Bulletin (No. 1-15) updates building code officials, specifiers, building owners and others on code evaluations and product approval requirements for roofing products. The bulletin centers on the requirements of the international codes as they relate to membrane roof covering systems. SPRI represents sheet membrane and component suppliers to the commercial roofing industry.

The bulletin is designed to update building code officials and members of the International Code Council (ICC) on the various ways roofing manufacturers can provide evidence of code compliance. The bulletin considers products that are referenced in the code, as well as new and innovative roofing products and assemblies. The SPRI Bulletin zeroes in on some practical options available to the building official or Authority Having Jurisdiction (AHJ).

In Bulletin No. 1-15, SPRI points out that Research Reports are not mandatory for single-ply roofing membranes that comply with standards referenced in the codes. Research Reports from approved sources are intended to assist in the approval of materials or assemblies not specifically provided for in the code. Therefore, the AHJ should not insist on a Research Report for a membrane roof system if the manufacturer has data available for the AHJ to review.

“Code officials are increasingly asking for a Research Report from single-ply roofing manufacturers to demonstrate code compliance,” says SPRI member Michael Beaton of Intertek, a global provider of product certification and performance-testing services. “While a research report should not be mandated since these products and systems are described in the code with specific requirements and referenced standards, a Research Report is an easy way for the manufacturer to provide the necessary information to the code official.

“SPRI’s ultimate goal in publishing Bulletin 1-15 is two-fold,” Beaton continues. “First, that code officials understand that a Research Report is a ‘convenience’ for single-ply roofing and should not be required if other relevant data is available. Second, that when the roofing manufacturer does choose to document compliance in a Research Report, code officials should be willing to accept a Research Report from an agency other than ICC Evaluation Service, provided the agency is accredited for this activity.”

SPRI Bulletin No. 1-15 is two-pages long and available for free viewing and download.

Garland’s new R-Mer Shield structural standing-seam roof system boasts a 2-inch-high vertical seam with an extruded aluminum clip and top rail system that provide wind-uplift performance, ensuring watertight protection in the harshest environments. Its symmetrically designed panel and cap allows for easy installation and provides flexibility during multiple phases of new construction, replacement or retrofit. The metal roof system can span over open purlins on slopes down to 1/4:12, making it suitable for retrofits over existing single-ply, built-up, modified bitumen and metal roof systems. The system design also provides a 1/2-inch clearance between the panel and substrate to increase ventilation beneath the panel.

GAF Plans to Open PVC Manufacturing Line in Cedar City, Utah

GAF announced plans to open a PVC manufacturing line at its commercial roofing plant in Cedar City, Utah. The line, which GAF expects to become operational as early as mid-2016, will transform the Cedar City operation into a full-service manufacturer and supplier of polyvinyl chloride (PVC) and thermoplastic polyolefin (TPO) single-ply membranes, as well as polyisocyanurate (ISO) insulation.

GAF also announced that it is actively considering locations for an additional plant in the eastern U.S. that will manufacture PVC, TPO and ISO. Known for its flexibility, ease of application and chemical resistance, PVC remains a single-ply solution among commercial roofing contractors.

“The Cedar City PVC line will strengthen GAF’s position as a full-service supplier of PVC, TPO and ISO. By manufacturing all three products at Cedar City and soon on the east coast, we will deliver economies of scale to our operations and quality service to our customers. This investment demonstrates our continued commitment to growth and leadership in the low-slope roofing market,” says Bob Tafaro, president and CEO of GAF.

“GAF is poised to leverage our track record of innovation and operational excellence. We’re ready to bring to the PVC market the same ingenuity and manufacturing expertise that have helped us to manufacture best-in-class TPO products.”

SPRI Revises Wind Design Standard Practice for Roofing Assemblies for Inclusion in the International Building Code

SPRI has revised ANSI/SPRI WD-1, Wind Design Standard Practice for Roofing Assemblies, to prepare the document for submission to and inclusion into the International Building Code (IBC). SPRI represents sheet membrane and component suppliers to the commercial roofing industry.

This Wind Design Standard Practice provides general building design considerations, as well as a methodology for selecting an appropriate roofing system assembly to meet the rooftop design wind uplift pressures calculated in accordance with ASCE 7, Minimum Design Loads for Buildings and Other Structures.

“Revisions to ANSI/SPRI WD-1 include additional insulation fastening patterns, along with more detailed practical examples,” says Task Force Chairman Joe Malpezzi. “This Standard Practice is appropriate for non-ballasted Built-Up, Modified Bitumen, and Single-Ply roofing system assemblies installed over any type of roof deck.”

In addition, SPRI has revised and reaffirmed ANSI/SPRI RD-1, Performance Standard for Retrofit Drains, in compliance with ANSI’s five-year cycle requirements. This standard is a reference for those that design, specify or install retrofit roof drains designed for installation in existing drain plumbing on existing roofs.

“It is important to note that the RD-1 Standard addresses the design of retrofit primary drains,” says SPRI President Stan Choiniere. “Local codes may also require secondary or overflow drains. SPRI will also be revisiting this standard after upcoming code changes are released.”
