Union Corrugating Has Added Standing Seam Manufacturing Capabilities

As part of its strategy to continuously improve service levels and lead-times, Union Corrugating has added standing seam manufacturing capabilities to their Orange, Va. manufacturing facility. The new equipment makes Union’s Advantage-Lok II, SL 150 and ML 150 profiles.

“We have redefined our mission statement to be the most convenient metal roofing supplier in the industry, and as a result, we are investing heavily in expanding production capabilities at our plant locations to improve lead-times,” says Keith Medick, Union’s CEO. “The new machinery will significantly reduce lead-times for our customers in Virginia, West Virginia, Maryland and Delaware by eliminating the need for shipments from our Fayetteville, N.C. plant. Customers can now expect lead-times for standing seam to be only a few days, a significant improvement from the one to two weeks in the past.”

The profiles are popular in residential and light commercial applications and Union has experienced strong growth with these products in recent years. Below is a description of the profiles being manufactured:

  • Advantage-Lok II – 1-inch rib screw flange standing seam
  • SL 150 – 1.5-inch rib snap lock standing seam
  • ML 150 – 1.5-inch rib mechanically seamed standing seam

Roof Report

DPR Construction is a national technical builder specializing in highly complex and sustainable projects. In less than 10 months, the design-build team researched, designed, permit-ted, and built a highly efficient and modern workplace with numerous innovative sustainability features.

In addition to natural daylighting, the office features an 87-foot zinc-clad solar chimney, which releases hot air from the building while drawing cooler air in; shower towers that act as evaporative coolers to regulate building temperatures; 87 operable windows designed to open and close automatically (based on indoor/outdoor temperatures); and two “vampire” shut-off switches to keep electrical devices (radios, cell-phone chargers, microwaves) from using plug energy when no one is in the office.

Access to the building was limited during construction. Spray foam roofing, which took about seven days to complete, had to be done in small quadrants because of the tight schedule as work was progressing in the other sections. The roofing workers were challenged by the barrel-shaped roof, which created footing difficulties, and the many penetrations that had to be flashed, including all PV support legs, Solatubes, skylights and HVAC penetrations. Work was completed in the middle of winter, so additional protections and efficiencies were required.

The circa-1972 building has been officially certified as a Net-Zero Energy Building by the Seattle-based International Living Future Institute through its Living Building Challenge program. It also has received LEED-NC Platinum certification from the U.S. Green Building Council, Washington, D.C.

A Standing-seam Roof Protects a Bank and Its Offices for the Long Term

Located on a high-traffic, signature intersection in Taylorville, Ill., Palmer Bank sought a timeless design that would visually represent its strength and stability to the community of just more than 11,000 people.

Design for the project was provided by The Redmond Co., Waukesha, Wis. The design team blended extensive detailing and profiling of the metal roof with a masonry façade to create an attractive prairie-style look.

“We clearly wanted to take advantage of the great location with a strong, timeless design,” says Andy Young, The Redmond Co.’s director of project development and construction manager on the project. “We presented two options to the bank regarding the roof … It was pretty unanimous that everyone liked the standing-seam profile look. We also liked the life-cycle cost of the roof since the bank plans to be the owner of this building for the long term.”

Installation of the standing-seam roof was completed by E.L. Pruitt Co., Springfield, Ill.

Installation of the standing-seam roof was completed by E.L. Pruitt Co., Springfield, Ill. The crew, which consisted of six tied-off workers, installed fascia, gutters, downspouts and soffit. Flashing components were custom-fabricated in E.L. Pruitt’s shop.

The metal is coated with ENERGY STAR-approved colors and is vented for optimal airflow, which greatly in-creases the roof’s longevity and energy efficiency. The metal was installed over roof-deck protection and a self-adhered underlayment.

According to Dallas Stephenson, E. L. Pruitt’s project manager, the roofing job took about six weeks to complete. He explains: “The most difficult part was doing all the seam layout because the product requires a progressive install, which means you can’t really start in the middle of the roof and work both directions. You have to start in a corner and work out of a corner and then work into a corner and then work back out of the corner.”

The metal was installed over roof-deck protection and a self-adhered underlayment.

Stephenson notes symmetrically lining up seams on the bank’s dormers and then across the roof was challenging. “Once we got all that figured out—took all the measurements on the job site and confirmed them—it went fairly smoothly,” he says.

“We knew the many hips and valleys would be somewhat of an installation challenge, but the installer did a terrific job,” Young notes.

Stephenson is quick to return the compliment: “Scott Brooks, site superintendent, and Andy Young from The Redmond Co. did an excellent job of picking a good team to build Palmer Bank. Everything just worked out great!”

Sustainable Home Features a Metal Roof for Durability and Energy Efficiency

A Metal Sales roof system has been chosen to top an ambitious Net-Zero building. Ronda and Nigel Farrar chose to work with Metal Sales on their 3,000-square-foot home in Escondido, Calif. The home overlooks Lake Hodges and was designed to be a model for green design by utilizing commercially available green building products.

The Farrar's dream of achieving a Net-Zero energy design was realized with help from Metal Sales Manufacturing Corp.

The Farrars are the owners of the new home and its surrounding sustainable farm. The home is one of San Diego County’s first LEED Platinum homes and is ENERGY STAR qualified. Their dream of achieving a Net-Zero energy design was realized with help from Metal Sales Manufacturing Corp.

“We chose a metal roof for our home because it was a sustainable material with a long life expectancy,” explains homeowner Rhonda Farrar. “Compared to other non-metal roofing materials, a metal roof is more durable and lighter, resulting in structural savings when building. Metal roofing also makes our home safer in the event of an earthquake or fire. Due to the reflectivity and energy efficiency of the metal, the roof contributes to a comfortable, energy-efficient living space.”

The home features 5,000 square feet of 24 gauge Magna-Loc standing seam roof panels in Antique Patina from Metal Sales. More than 100 panel colors from Metal Sales are listed with ENERGY STAR and improve energy efficiency by reflecting sunlight. This provides an energy savings by reducing the amount of energy needed for cooling the home. The steel panels are also 100 percent recyclable and contain a high percentage of recycled material. Each of these factors contributes to the home’s LEED Platinum certification.

"We chose a metal roof for our home because it was a sustainable material with a long life expectancy," explains homeowner Rhonda Farrar. "Compared to other non-metal roofing materials, a metal roof is more durable and lighter, resulting in structural savings when building."

“The longevity, reflectivity and energy-efficient qualities of a metal roof make it an ideal choice for a sustainable home,” says Drew Hubbell, owner of Hubbell & Hubbell Architects. “The cool metal roof reflects heat, reducing cooling needs and allowed for easy installation of the photovoltaic panels without penetrating the roof. The standing seam roof also fit the architectural style of the home with an antique patina finish. The simple lines of the roof fit in with the modern design of the home and complements the home’s exterior.”

The project team consisted of homeowners Rhonda and Nigel Farrar; architect Hubbell & Hubbell Architects, San Diego; general contractor Gaitaud Construction, San Diego; and roofing contractor Victor Contracting & Roofing, Escondido.

Research Study Shows Certain Metal Roofs Can Last at Least 60 Years

The Metal Construction Association (MCA) has released new research findings that conclude that certain metal roof systems can last at least 60 years, meaning they do not require replacement during a commercial building’s service life.

“This study is a breakthrough for the metal construction industry because it finally provides third-party, scientific data that backs up the long held stance that 55 percent Al-Zn coated steel standing seam roofing systems are very durable, economic, and can be better for the environment,” said Scott Kriner, Technical Director, Metal Construction Association. Most non-metal roofing systems require one or more full replacements within a typical building’s 60-year service life, which is costly and often adds to the solid waste stream in landfills.

The study, sponsored by MCA and the ZAC Association, was conducted with oversight of three independent consulting firms which analyzed low-slope, unpainted 55% Al-Zn coated steel standing seam roofing, in a wide range of environments across the U.S.

This type of roof material is known by many trade names throughout the world, principally GALVALUME and Zincalume in the United States. It is very common on low rise commercial buildings such as warehouses, schools, distribution centers, shopping centers, exposition halls and other facilities. Experts estimate that the market size for this type of low slope roofing in the U.S. is over 350 million square feet.

The study incorporates the results of multiple field inspections, independent laboratory analyses of metallic corrosion of the roof panels, components and sealants, and includes assessment of all integral ancillary components that impact the end of roof service life.

The research team selected 14 building sites in five climate regions of various geographies in the continental United States, exhibiting a spectrum of climates related to heat and humidity including Hot-Dry, Hot-Humid, Cold-Dry, Cold-Humid, and Moderate-Acid. The precipitation acidity also varies considerably from one site to the next over this broad geography.

The research study concluded that the expected service life of an unpainted 55 percent Al-Zn coated steel standing seam roof constructed today in a wide range of environments using best practices can be expected to be in excess of 60 years, a value that equals the assumed building service life as described in the USGBC’s Leadership in Energy and Environmental Design building rating program, version 4.

In the study, the steel panel roofs experienced corrosion rates that conservatively project service lives well beyond the service life of most buildings. The range depends on the climate and the local precipitation pH.

The study also confirmed that these types of metal roofs resist corrosion even in “weak” spots, such as sheared edges and panel profile bends. Inspections showed an absence of significant red rust after up to 35 years, indicating exceptional corrosion resistance in areas susceptible to exhibiting the first signs of corrosion.

The study acknowledges that all roof systems require a regular maintenance program (at least annually) to clean off debris and to inspect the condition of the roof in order to achieve the kind of service lives shown in this study. While low-slope steel standing seam roof systems were projected to last up to 60 years, ancillary components (such as fasteners) may need to be replaced during the roof life, but this represents significantly less than 20% of a total roof replacement cost.

“We are planning to conduct more studies on different types of metal roofing, and in some cases we expect similar or even better results in terms of roof service life,” adds Kriner. “We think these studies will help to motivate building owners and architects to specify metal roofing more often.”

The report was authored by Ron Dutton, Ron Dutton Consulting Services LLC; Rob Haddock, Metal Roof Advisory Group; Chuck Howard, Metal Roof Consultants and Scott Kriner, Metal Construction Association. The report was also peer reviewed by Morrison Hershfield laboratory in Canada.
