Roof Materials

To meet design objectives, four different PAC-CLAD products were selected. The roof uses 20,500 square feet of 16-inch, 24-gauge Silver Metallic Tite-Loc Plus panels. The façade features 7,800 square feet of Precision Series wall panels finished in Sierra Tan and installed vertically. Complementing the façade is 4,000 square feet of 12-inch Almond Flush panels installed as soffit. In addition, 4,520 square feet of 24-gauge Medium Bronze flat sheet was used for fascia and trim.

“The Tite-Loc Plus panels were long—85 feet—and were rollformed onsite,” says Bill Kimbrough Jr., estimator and project manager for Modern Heating Cooling Roofing. “Getting them up to the high roof was a challenge. All other profiles were fabricated and delivered by Petersen. Currently, PAC-CLAD is about the only product we use.”

Roof Report

Workforce Essentials is a private, non-profit organization providing workforce development services for the Tennessee Department of Labor in a nine-county area in the middle of the state. Located on a highly visible urban-infill site, the new Workforce Essentials headquarters and career training center is situated at a “gateway entry” intersection to the downtown district. The new 40,000-squarefoot facility consolidates services that had been provided at agency offices previously scattered around the city. After initially considering renovation of an aging building on the site, the organization’s board of directors determined that construction of a new, energy-efficient headquarters was a better course of action. Good visibility and an easily identifiable aesthetic were important to site selection and building design criteria.

Different departments within the building are visually and strategically defined in separate wings and entrances. The administrative office wing to the south is defined by a vertical brick corner tower and sloping metal roof planes and cladding. The larger career training center portion of the building is introduced by metal wall panels in a calming color palette of Sierra Tan. Thematic entry canopies, protruding aluminum sunshades and aligned horizontal fenestration tie together the architectural composition. The overriding idea is for the building to serve as a machine with different parts working together for a common purpose.

Brad Martin, principal/designer at Lyle Cook Martin Architects, explains: “Workforce Essentials has a variety of regional offices throughout the area it serves. All are different and very few are freestanding. The organization has never really had a corporate look or identity. Now, with this new building, we can incorporate its design features and architectural aesthetics into future new buildings and renovations and begin to develop an iconic look.”

Joint and Termination Sealant Designed for Large Joints, Roof Termination Bars

JTS 1 joint and termination sealant from Mule-Hide Products Co. The new JTS 1 joint and termination sealant from Mule-Hide Products Co.allows contractors to quickly and easily seal large joints and roof termination bars – including those submerged under water – with no sagging or shrinking and minimal odor. According to the manufacturer, the 100-percent solids, moisture-cure urethane sealant delivers excellent adhesion to EPDM and PVC membranes, concrete, masonry, wood, vinyl and other common building materials. Primer is required when using it on TPO membranes.
 
The joint and termination sealant is designed to offer exceptional workability for quick, easy application in both dry and wet surface applications. It has a tack-free time of just 30 minutes. The solids content of JTS 1 eliminates shrinking and sagging. The sealant can, therefore, be used to provide watertight closure of joints up to 2 inches wide and 1 inch deep.
 
JTS 1 is isocyanate-free, enabling it to be packaged in durable plastic cartridges without losing workability. Unlike cardboard tubes, the cartridges can be submerged under water to repair roof leaks, gutters and downspouts. They also better withstand the rigors of transportation, storage and jobsite conditions without becoming damaged.
 
Solvent-free JTS 1 has minimal odor. Its volatile organic compound (VOC) content of less than 10 grams per liter makes its use allowable in areas with VOC restrictions. It is available in eight colors – white, black, bronze, gray, limestone, wicker/tan and terra cotta.

Roofing Adhesive Features One-Step Application Process

Helix Low-Rise Adhesive is ready to use from the container, no mixing required.

Helix Low-Rise Adhesive is ready to use from the container, no mixing required.

With a one-step application process, Helix Low-Rise Adhesive from Mule-Hide Products Co. provides adhesion of approved roof insulations, thermal barriers, cover boards and fleece-backed single-ply membranes to a variety of roofing substrates.
 
The polyurethane foam is applied in a single step. Both parts of the adhesive are ready to use from the container – no mixing required – and are applied simultaneously in a 1:1 ratio through a static mix tip. It is applied in continuous ribbons or beads spaced 4, 6 or 12 inches apart, depending on the project and code requirements. There is no overspray, and it cures in minutes.
 
Helix Low-Rise Adhesive contains no volatile organic compounds (VOCs), chlorofluorocarbons (CFCs) or hydro chlorofluorocarbons (HCFCs). 
 
It does not require mechanical fasteners, maintaining a puncture-free vapor retarder, preventing thermal bridging and protecting the structural integrity of the roof deck.
 
The bond created by Helix Low-Rise Adhesive provides wind uplift resistance, allowing it to be used on buildings in higher wind zones. In addition, it provides hail resistance when used as an adhesive for fleece-backed membranes.
 
Helix Low-Rise Adhesive comes in cartridge twin-pack tubes or two-tank sets. Both include one container of each of the adhesive’s two components – Part A and Part B. Cartridge twin-packs cover approximately 200-600 square feet of roof and tank sets cover approximately 1,000-3,000 square feet of roof, depending on bead spacing.
 
The cartridges fit most dispensing guns currently available on the market. Tank sets come with a Helix Gun Assembly (25-foot dual-hose with attached spray gun), petroleum packet, wrench, and 10 Tank Static Mix Tips. Contractors need not purchase specialty pumps or spray rigs. No external power source is required to run application equipment.

ROOF MATERIALS

Wagner Roofing was awarded the complete replacement of all roof systems. These included an upper double-lock standing-seam copper roof system, a bullnose copper cornice transition, slate mansard, 34 dormers with double-lock standing-seam copper and fascia metal, eight copper hip metal caps and a continuous built-in gutter with decorative copper fascia. Each of the dormers also had a copper window well.

The upper standing-seam roof was removed and replaced with 24-inch-wide, 20-ounce copper coil rollformed into 1-inch-high by 21-inch-wide continuous standing-seam panels that matched the original profile. The eave bullnose, which also served as the mansard flashing, was removed and returned to Wagner Roofing’s shop where it was replicated to match the exact size and profile.

The 34 dormer roofs were replaced with 20-inch-wide, 20-ounce copper coil formed into 1-inch-high by 17-inch- wide continuous standing-seam panels. The decorative ornate fascia of the dormers was carefully removed and Wagner’s skilled craftsmen used it as a template to develop the new two-piece copper cornice to which the roof panels locked. The cheeks and face of the dormers were also re-clad with custom-fabricated 20-ounce copper.

The oversized built-in-gutter at the base of the slate mansard was removed and replaced with a new 20-ounce copper liner custom-formed and soldered onsite. The replacement included a specialty “bull-nosed” drip edge at the base of the slate and an ornate, custom-formed fascia on the exterior of the built-in gutter. The decorative copper fascia included 85 “hubcaps”, 152 “half wheels” and 14 decorative pressed-copper miters. The original hubcap and half-wheel ornaments were broken down and patterns were replicated. Each ornamental piece was hand assembled from a pattern of 14 individual pieces of 20-ounce copper before being installed at their precise original location on the new fascia. The miters were made by six different molds, taken from the original worn pieces, to stamp the design into 20-ounce sheet copper.

In all, more than 43,000 pounds of 20-ounce copper was used on the project.

ROOF REPORT

Maury Hall was built in 1907 and was designed by Ernest Flagg. Flagg designed many of the buildings at the U.S. Naval Academy, including the Chapel, Bancroft Hall, Mahan Hall, the superintendent’s residence and Sampson Hall. His career was largely influenced by his studies at École des Beaux-Arts, Paris. Examples of Flagg’s Beaux-Arts influence can be found in the decorative copper adorning the built-in gutter on building designs.

Maury Hall currently houses the departments of Weapons and Systems Engineering and Electrical Engineering. The building sits in a courtyard connected to Mahan Hall and across from its design twin, Sampson Hall.

Air and Vapor Barrier Creates a Seal Between a Low-slope Roofing System and the Building Below

F1 Air & Vapor Barrier from Mule-Hide Products Co.

F5 Air & Vapor Barrier from Mule-Hide Products Co.

F5 Air & Vapor Barrier from Mule-Hide Products Co. allows contractors to quickly and easily create an air- and vapor-tight seal between a low-slope roofing system and the building below.

F5 Air & Vapor Barrier is compatible with a wide variety of roofing systems and can be used on primed substrates, including concrete, plywood, exterior gypsum, DensDeck Prime and SECUROCK. It also can serve as a temporary roof for up to 120 days while work on the finished roofing system is completed.

The membrane is a 40 mil-thick composite consisting of 35 mils of self-adhering rubberized asphalt laminated to a 5 mil-thick woven polypropylene film. Rolls are 39 inches wide and 75 feet long and cover approximately 244 square feet of substrate surface.

F5 Air & Vapor Barrier’s factory-controlled thickness helps ensure that the membrane has uniform barrier properties, reducing moisture movement through the roofing system and helping keep conditioned air inside the building and unconditioned air outside. The woven polypropylene film makes the membrane highly resistant to tears and punctures. The non-skid surface helps keep contractors safe on the job site and is suitable for the bonding of subsequent layers of the roofing system.

A siliconized one-piece release liner prevents the material from bonding to itself in the roll and is easily removed during installation of the barrier.
