ROOF MATERIALS

Approximately 423 squares of 1/2-inch-thick, 18-inch-tall by random width Unfading Green Slates were installed by hand on the project. This was close to 750,000 pounds of slate, or 375 tons.

About 3,000 feet of custom copper gutters and downspouts, conductor heads and 100 squares of painted standing-seam panels were fabricated, and pre-built copper clad dormers and decorative copper cornices were installed.

The project also included 35 squares of copper standing-seam roofing, 25 squares of soldered copper flat-seam roofing and 115 squares of copper wall cladding. About 58,000 pounds of copper were installed on the brewery.

Everything on the building is oversized and that meant everything had to be built to support the heavy structural loads and live loads from wind and mountain snow. The large roof faces called for 10-inch custom copper gutters. When you have gutters that large in the mountains of North Carolina you have to consider the extraordinary weight of the annual snow.

In addition to snow guards being installed on the slate roof, custom 1/4-inch-thick copper gutter brackets fastened the gutter to the fascia. It is typical on steel-framed construction, particularly on this scale, that the framing is out of square and there is widely varying fascia and rake dimensions.

However, these items should not appear out of square or have varying dimensions. Great care had to be taken to measure and custom bend onsite all the detail flashings so everything appeared perfect. This took many skilled craftsmen, a great deal of time and the absolute drive to provide the highest quality work.

Outlet Collection at Niagara Niagara-on-the-Lake, Ontario, Canada

Roof Materials

The largest open-air outlet mall in Canada features approximately 23,000 square feet of PTFE fiberglass membrane walkway canopies. The membrane canopies exhibit a flying-mast cone design that provides relief from the elements and creates a signature look for the shopping center.

PTFE, or polytetrafluoroethylene, is a Teflon-coated woven fiberglass membrane that is durable and weather-resistant. PTFE fiberglass membranes can be installed in climates ranging from the frigid arctic to the scorching desert heat with a project life in some cases exceeding 30 years.

PTFE fiberglass coating is chemically inert, and the low-surface free energy of the material results in an electrical-grade fabric membrane that is readily rinsed by rain-water. It is also immune to UV radiation. This combination makes PTFE-coated fabric membrane ideal for projects requiring weather endurance and fire resistance.

PTFE fiberglass is ENERGY STAR- and Cool Roof Rating Council-certified. During scientific tests of its solar properties, it was discovered that PTFE fiberglass membranes reflect as much as 73 percent of the sun’s energy while holding just 7 percent on its exterior surface. Certain grades of PTFE fiberglass can absorb 14 percent of the sun’s energy while allowing 13 percent of natural daylight and 7 percent of reradiated energy (solar heat) to transmit through.

Roof Report

Located beside the Queen Elizabeth II Highway, less than 20 kilometers from the U.S. border, the 520,000-square-foot shopping center features 102 retailers, including Canada’s first Pandora outlet, White House Black Market outlet and Bass Pro Shops Outpost. Other sought-after brands at the center include a Kate Spade Outlet, NIKE Factory Store, Calvin Klein Outlet and Michael Kors Outlet.

The Niagara Outlet Collection was developed to attract shoppers and visitors who might have otherwise crossed the U.S. border to shop in the Fashion Outlets of Niagara Falls, the Walden Galleria or the Boulevard Mall. David Baffa, Ivanhoé Cambridge senior vice president of retail development, said the developer wants the new outlet collection to be part of the Niagara experience.

Outlet Collection at Niagara is committed to corporate responsibility and environmental sustainability and has a number of design features throughout the property to raise awareness of its green initiatives. Its canopies make the open-air concept possible, reducing energy consumption because the common areas do not need to be heated or cooled. Some of the public buildings, like guest services and the eatery, have been designed so that they can be opened to the outdoors in favorable weather, thus saving energy and connecting people to the outdoors.

Corrugated Metal Applied in Unusual Ways Brings a 1918 Building into the 21st Century, and a TPO Roof Protects Its Icon Status

Dorchester is Boston’s largest neighborhood and one of its most diverse. In July 2013, the Four Corners commuter rail station opened in the Mount Bowdoin section of the neighborhood, setting in motion plans to bring more transit-oriented buildings to Dorchester. Among the first projects to meet this goal is the AB&W Building, a mixed-use facility located about one block from the Four Corners station.

Originally built in 1918 as a car dealership that sold Model T’s, the AB&W Building has become a neighborhood icon.

Originally built in 1918 as a car dealership that sold Model T’s, the building has become a neighborhood icon. Therefore, even though the goal was to create an active center that connected tenants and others with the new commuter station, Project Architect P. Nicholas Elton, AIA, a partner in Elton + Hampton Architects, Roxbury, Mass., still desired to connect the new development to its surroundings as much as possible. “The intention was to create a development that was a little denser than the rest of the neighborhood but still respected and tried to be a little like the neighborhood,” he says.

To achieve this, the decision was made to maintain the front façade of the original building and integrate it with all new construction. Elton used specific building materials to pay homage to the surrounding area. For example, a yellowish brick on the front of the new second and third stories of the AB&W Building mimics the brick used on the 1930s-era building across the street. The addition of fiber-cement and corrugated-metal siding breaks up the enlarged AB&W Building’s scale so it better fits in its location.

Elton, who is a fan of corrugated metal, decided also to have some fun with the material, flexing it in unusual ways for overhangs above windows and doors. “When you start using materials that you are using on the walls on the roof, then you get to play a little game,” he says. “The material will come down a wall and wrap into the roof; there are a lot of materials you can’t do that with but you can when you use corrugated.”

It took a team of three metal fabricators from Lancaster Enterprises Inc., a family roofing business in Dedham, Mass., to carefully curve and flex the corrugated metal to meet Elton’s specifications. Meanwhile eight to 10 of the metal fabricators’ colleagues were installing a watertight TPO membrane on the AB&W Building’s six newly constructed roofs.

The 32,096-square-foot AB&W Building features 24 affordable-housing units, primarily rentals with a few coop ownership opportunities, and 3,300 square feet of ground-floor retail space.

OLD BECOMES NEW

Elton + Hampton Architects concentrates its work on what the firm’s partners—Elton and Bruce M. Hampton, AIA—refer to as socially relevant projects. The firm almost exclusively works with non-profit organizations on affordable housing and housing for special populations, as well as community-resource buildings.

One retail space is an art gallery and there currently are conversations to merge the other two retail locations for a restaurant specializing in Caribbean cuisine.
