Kathleen and Tom Elam Center, Univ. of Tennessee

Texas-Style Re-Roof

Home of Intercollegiate Athletics and the Department of Health and Human Performance at the University of Tennessee Martin campus, the Kathleen and Tom Elam Center needed its metal roof replaced so McElroy’s 238T symmetrical standing seam panels were selected.

SlopeShield Plus SA Self-Adhered

Vapor Sandwich Elimination

SlopeShield Plus Self-Adhered (SA) is a highly vapor-permeable roofing underlayment air barrier (AB) material. As an air barrier membrane product, SlopeShield Plus SA stops the movement of air, eliminating damaging moisture transferred by air, and maximizes energy savings while meeting energy code requirements. As a vapor permeable membrane (30 perms) product, it allows the remaining vapor to escape the roof assembly through diffusion. The combined unique features allow the creation of a “self-drying roof,” eliminating a troubling phenomenon called the “vapor sandwich,” when moisture becomes trapped in the roofing assembly.Judge’s Comment: “Good thermal/mo

On the Wing

Heritage Elementary School in Tahlequah, Okla., by Crafton Tull, features nearly 87,000 sq. ft. of Galvalume Snap-Clad panels. The roof design on each classroom wing features three different levels that minimize mass and offer a sleek look. The 24-gauge steel Snap-Clad panel profile was specified as an option by the architect. “The detailing was complicated and required custom tapered valleys and transitions from each level of the wings,” said Jason Irvin, branch manager of Harness Roofing in Tulsa, the installing contractor. Many of the panels were up to 60-ft. long and were fabricated on-site using Petersen’s portable roll-forming equipment provided from its Tyler, Texas,

Roof as a Sponge

Boston’s 101 Seaport–a 17-story, 440,000-sq.-ft. office building–is topped off with 5,000 sq. ft. of living roof that will reduce the need for onsite stormwater management systems. The soil in the green roof system, made by LiveRoof and designed by Copley Wolff Design Group, Landscape Architects and Planners, acts like a sponge and absorbs excess rainwater, thus reducing the impact of a new building on the municipal storm drainage system and surrounding watershed by reducing flooding and erosion.

Christ Church Cathedral, Vancouver, British Columbia

A Newsworthy Roof-Raising

A 22-year renovation of Christ Church Cathedral in Vancouver, British Columbia, was completed recently as workers finished their efforts replacing the 1894 structure’s massive roof. Designers with Vancouver’s Proscenium Architecture & Interiors, Inc., opted for standing-seam zinc for the complicated project, which required extensive detailing to address a large number of pitch changes and other transitions.
