Duradek, home of the original Walkable Roofing Membrane, introduces the Park Rail Top Rail profile, a top rail for plenty of support.

The Park Rail Top Rail offers durability and a continuous top rail look while using up to a 3-inch square post.

Park Rail Top Rail is suitable for picket and glass systems allowing your project to combine the features and advantages of both systems, yet still providing a consistent look throughout.

The new Park Rail Top Rail profile has a much wider look than the average aluminum top rail profile. It is similar in appearance to what has been recognized as a 2 by 4 (wood) size, but this top rail is not vulnerable to the elements the same way as wood.

It is constructed with durable powder-coated aluminum and is made to last without the need for maintenance.

Barker Ends Career at Petersen Aluminum Corp.

Bill Barker concluded 27 years in the metal market working for Petersen Aluminum Corp., a career which endured such changes as consolidation on the producer side, Reynolds closing its doors, the influence of imports on pricing, numerous customers going out of business and many more challenges.

“I enjoyed my career at Petersen,” Barker says. “Management treated me very well—excellent, in fact, and I’m grateful. They allowed me the freedom to handle my accounts as I deemed necessary. There was no micro managing, which allowed me to succeed.” Barker is looking forward to a semi-retirement, and will keep his “fingers in the pie. I have an excellent relationship with my customer base.”

Petersen Aluminum CEO Mike Petersen wished Barker well. “Our good friend and long-time associate Bill Barker has retired from Petersen Aluminum Corp., completing a 27-year career that included responsibility for Chicago industrial sales, glass industry sales, and management of our stainless steel product line,” Petersen said. “Bill developed a diverse and loyal customer base through his dedicated efforts and he will be missed by his friends, colleagues and fellow employees at Petersen. As the cake we shared with him said, ‘Retire in Peace, Bill’—but better yet, retire in prosperity!”

A Bermuda-style Roof Composed of Aluminum Includes Intricate Hips, Ridges, Vents and Gutters

Sometimes the most interesting roofing jobs don’t start out as planned. That was the case for Iain Fergusson, owner of Highland Roofing Co., Wilmington, N.C., when he bid on an asphalt shingle reroof for an 11,000-square-foot ranch-style home located along a coastal creek in Wilmington.

After he submitted his bid, the architect, Michael Kersting of Michael Ross Kersting Architecture, Wilmington, asked for an option for standing-seam metal roofing, which is the specialty with which Fergusson established Highland Roofing in October 2005. Although Fergusson was confident about his crew’s ability to install an exceptional metal roof, he became a little nervous when the next request came from the architect.

“We were asked to price out an option for Bermuda-style metal roofing,” he recalls. “Of course I knew what a Bermuda roof was but I had no experience with it; you don’t get much opportunity to do that here.” However, Fergusson put the price together and won the job.

On the island of Bermuda, roofs are constructed of rectangular slabs of local limestone that are mortared together in a stepped pattern over a hip roof frame. The distinctive beauty of these roofs has begun to enter the U.S. though traditional stick-frame housing doesn’t lend itself to heavy limestone. The Wilmington residence consists of a wood-framed roof and brick veneer walls that would not support the weight of limestone, so Kersting opted for metal—specifically aluminum, ensuring the roof would be fully warranted in the coastal environment.

Once the team began moving forward with the Bermuda-style roof, a final set of plans made Fergusson even more anxious. “The plans had all kinds of details that came out of left field—built-in gutters and EPDM sections of the roof,” he says. “The big curve was that the architect wanted to make a feature out of the hips and ridges, because traditional Bermuda-style roofing is wrapped seamlessly around the hips and looks really neat and clean. Kersting knew that it wouldn’t be possible with sheet metal; it would have to be cut and mitered on the corners, so he had the idea of putting raised 2 by 4s on all the hips and ridges and having us wrap that.”

These details are what make this home’s roof impressive and where most of the work came in for Fergusson, who acted as project manager, and his team, which consisted of Roofing Superintendent Richard Hill, Sheetmetal Fabricator Michael Mai and a four-man install crew led by Foreman Marvin Mungia. After considering different panel sizes to ensure oil canning would be avoided, Kersting and Fergusson settled on 0.032 aluminum in 12-inch panels, and Fergusson’s crew was ready to put its skills to the test.

Although Fergusson established Highland Roofing in 2005 with a focus only on residential metal roofing, he expanded into all types of steep-slope products within the first couple years. In 2009, Fergusson began moving into the commercial roofing market; today, 70 percent of his revenues are commercial. In the residential sector he has a good mix of reroofing and custom new construction. It’s the custom side that Fergusson takes most pleasure in. “I really enjoy custom residential so much because it’s challenging and so different and it’s generally the most aesthetically appealing project we get to do,” he says.

Because of the firm’s focus on custom work, Fergusson’s crew already was proficient in good communication with each other. But the complexities of the Wilmington job would put Fergusson in direct communication with Kersting, which is unusual. “A lot of times the architect is insulated from the roofing contractor by the GC on the job,” Fergusson explains. “Communicating directly with the architect was a good thing. We could explain which of his ideas would and wouldn’t work.” In addition, Fergusson brought roofing samples to Kersting’s office where they were tweaked before 1-square mockups were tested onsite to see how the installation would be completed along the hip.

Sealant Adheres to Various Substrates

Titebond Roof Plus Sealant

Titebond Roof Plus Sealant

Varied substrates comprise roofing materials, and contractors need a roofing sealant sufficiently versatile to adhere to as many of them as possible. Now, they have one, with the introduction of Titebond Roof Plus Sealant.

Titebond developed its newest roof sealant for a wide variety of roofing applications, such as metal trim, solar roof systems, architectural metals, painted metals, aluminum and general roofing projects. It provides excellent adhesion to a range of substrates: shingle and tiled roofs, sheet roofing, metal roofs, wood forms, flashings, edge and ridge tiles and liquid applied roofs. In addition, contractors can apply the sealant in temperatures from 20 F to 100 F, advancing its status as a great all-around roof sealant.

Titebond develops its adhesives and sealants with the professional contractor in mind, so it’s no surprise that its newest sealant offers performance characteristics that will appeal to the pro – and, by extension, the skilled DIYer. Beyond the wide application temperature range, Roof Plus can speed up application, increasing contractor productivity. The ready-to-use formula requires no messy, time-consuming mixing; the contractor simply inserts the cartridge in the gun and tools for quicker application and neater joints. It easily fills properly prepared joints one-quarter to two-inches wide. In addition, its clear formulation blends with most substrates – although the contractor can paint it with any non-rigid paint within just two hours.

However quick the application time, when cured, Titebond Roof Plus Sealant is an extremely long-lasting, supple sealant. It provides a weather-tight seal with 560 percent elongation and 25 percent total joint movement. The contractor can leave the job site confident that the sealant will meet high performance standards.

The newest Titebond sealant also complies with ASTM C-920 Type S Grade NS Class 12.5 Use T, NT, M, A and O; Federal Specification TTS-00230C Type II Class B; and SCAQMD Rule #1168.

Titebond Roof Plus Sealant is available in 10.1-ounce cartridges through building materials suppliers and hardware stores. It joins a full line of Titebond caulks and sealants for siding, roofing, multi-purpose, interior and specialty applications.
