Leaky bank

Just 10 years ago, Essex Savings Bank opened its new two-story headquarters in Essex, Conn. But when the building's steel roof began to leak at the joints, the bank was forced to replace the roof. Installed by Hartford, Conn.-based contractor Ernest Peterson Inc., the new 16,900-sq.-ft. standing-seam copper roof features a zinc/tin alloy that withstands corrosion, needs no painting and keeps its natural gray patina for years.

Making progress

When the 85,000-sq.-ft. Center of Progress Building at the New York State Fairgrounds opened its doors in 1908, its architecture was every bit as grand as its name implied. But the 90 years that followed took their toll on the building's original galvanized iron roof, which had been covered several times with asphalt shingles. The building was recently restored to its original grandeur thanks to a new steel roof installed by Albany, N.Y.-based Horizon Roofing & Sheetmetal Inc. The roof is composed of more than 80,000 square feet of 22-gauge steel panels coated with a fluoropolymer finish that resists fading and chalking. Because of the roof's size, standing some 64 feet high and 500 feet long, the roof panels were formed, rolled and bent onsite by Horizon Roofing.

Curved copper

When Fulton Bank chose to locate its new headquarters in Lancaster, Pa.'s Penn Square urban renewal development, local architect David Lynch & Associates designed the facility to fit in with the surrounding buildings, a number of which have copper roofs. The architect specified R-Mer Span curved standing-seam copper roof panels, which were installed in 70-ft. sections to cover the roof in one pass, reducing the possibility of leaks. The roof system features a snap-lock seam for fast installation.

Metallic ceramic

Metal roof that tops the International Buddhist Progress Society's new worship center in Houston mimics in color and finish the glazed ceramic tiles used on ancient Buddhist temples. The steel roof panels are approved by the Texas Department of Insurance for both wind and impact resistance.

Roof over roof

Attachment system helped Cairo, Ga.-based contractor Allen Industrial Contractors reroof the 40,000-sq.-ft. Brookwood School in Thomasville, Ga., without removing the roof. The contractor fastened the subpurlin through the flat-pan section of the existing metal roof into the structural purlin below, then installed the new roof on top of the Roof Hugger attachments.

Community service

To blend in with surrounding industrial buildings, Minneapolis-based Sjoquist Architects specified a standing-seam aluminum roof for East Side Neighborhood, a 60,000-sq.-ft. building that serves the Minneapolis community with high school, daycare and social-services facilities. Metal panels were used to create four light shafts designed to mimic exhaust vents, and sloped metal-roof canopies were designed to appear as loading docks. The project required 3,000 square feet of SL-16-0 roof and wall panels.

Police protection

To protect the Michigan State Police's new Crime Lab from wind uplift and snow loads, architect Hobbs & Black of Ann Arbor, Mich., chose a SRS 2 standing-seam metal roof as well as Super-Rib and 1W-10-A panels for the building's second story and equipment enclosures. The roof and wall-panel systems offer a weather-tight seal and are designed to retain their "police blue" finish without fading or chalking.

During school special

When Lloyd Mann Primary School's 36,600-sq.-ft. flat roof started ponding water and leaking, a new standing-seam metal roof was installed over the existing roof with no interruption of school. The new roof provides the proper pitch to eliminate standing water as well as better thermal performance thanks to a reflective surface and 6 inches of fiberglass insulation.

Home for the Spruce Goose

The world's biggest airplane, the 219-ft. Spruce Goose, composed mostly of laminated birch plywood, has found a home in the Evergreen Aviation Museum in McMinnville, Ore., just south of Portland. Housing the huge memento of the life of the late billionaire Howard Hughes requires 140,000 square feet of roof. Six months in completion, the museum's roof membrane protects against Oregon's wet weather and cold winters.

Coated 6-in. screws secure battens through the insulation to the steel deck. A deep green steel shake with the look of hand-split wood caps the roof, along with a custom-built 21-in.-deep stone-coated steel fascia.

Flexing its stuff

Because building owners required that no asphalt fumes be emitted during reroofing of their San Francisco office building, the Flex FB adhered roofing system was installed. The system is based on DuPont Elvaloy KEE ketone ethylene ester and applied with Flex water-based substrate adhesive.

Protecting the protected

Lightguard Protected Membrane Roof Insulation guards the membrane system and saves energy. The tight, closed-cell structure of the product's foam insulation panels resists all forms of water penetration and protects the roofing membranes from heat, ultraviolet rays, temperature swings and freeze-thaw cycles. Weighing 4.5 pounds per square foot, the product is well suited for installation of single-ply and built-up roofing requiring a lighter-weight roofing system.

Barbie's reflective roof

In need of a durable roof membrane to stand up to the strong Texas winds and extreme heat, toy manufacturer Mattel Inc. selected the Sure-Weld thermoplastic olefin membrane to cover its new 1 million-sq.-ft. distribution center in Fort Worth. The white membrane reflects the sun's heat and lowers the surrounding air temperature.

Coolest of the cool

Cool roof systems provide waterproofing, energy conservation, life-cycle cost saving, environmental benefits and greater building comfort. These systems offer high solar reflectivity and readily release any heat they do absorb. Systems for low-slope commercial roofing fall into two basic categories: light-colored single-ply membranes and light-colored fluid-applied coating-based systems. Cool roofs can slash air-conditioning loads by 20 to 50 percent.

Easy-spread mastic

Designed for strength, the TAM-PRO M3 Mastic is a styrene-butadiene-styrene-modified, low-solvent cold-applied mastic. The product is squeegee applied. The cold-applied method of modified roll roofing installation has gained popularity because it is said to be safer, easier and faster to apply.
