Metal Roofing and Siding Enhance Waste Collection Building

The Elk Grove Special Waste Collection Center celebrate the industrial chic nature of dealing with hazardous waste products with metal roofing and wall panels.

Metal roofing and siding help the Elk Grove Special Waste Collection Center celebrate the industrial chic nature of dealing with hazardous waste products.

The city of Elk Grove, Calif.’s Special Waste Collection Center opened in April 2014 with a commitment to a cleaner and greener community. The center, which features AEP Span’s architectural metal panels, has earned LEED Gold Certification and, to date, has accepted nearly 300,000 pounds, or 130 tons, of recyclable materials diverted from local landfills.

“With the Elk Grove Special Waste Collection Center project, we wanted to express and celebrate the industrial chic nature of dealing with hazardous waste products at the same time creating a safe, warm and comfortable environment for the center staff,” says Eric Glass, AIA, LEED AP and principal of Santa Rosa, Calif.-based firm Glass Architects. “The project is designed to take a heavily abused, neglected and contaminated site and revitalize it, turning it into a protected habitat.”

“Metal siding and roofing products were a natural choice for this project,” Glass adds. “The inherent durability and recycled content material speaks to the overall mission of this facility. The horizontal and vertical fluted siding creates a strong form and texture, enhancing the building’s character.”

The Elk Grove Special Waste Collection Center project features AEP Span’s 24-gauge Reverse Box Rib in ZACtique II on the lower section of the wall application; 24-gauge HR-36 in Metallic Silver in the upper wall and canopy application; 24-gauge Prestige Series in Metallic Silver in a soffit application; 16-inch, 24-gauge SpanSeam in Hemlock Green in a roof application; and 24-gauge Curved Select Seam in Hemlock Green for the curved canopy application.

The $4.6 million center is the first, and only, facility of its kind in the nation powered by solar energy.

Roof Materials

Interstate Roofing recommended Valoré Slate in the Villa color blend of medium and dark grays for the reroofing project. Valoré synthetic slate roofing tiles are made using proprietary VariBlend technology to form varying shades from tile to tile, creating an infinite number of color shades. Each single-width synthetic slate roofing tile is crafted using virgin polymer resins to guarantee a sustainable product. Valoré Slate tiles come in 12-inch tile widths with a 1/2-inch tile thickness, making it a lightweight yet realistic slate roofing tile option. (The Valoré Slate product line no longer is available.)

Roof Report

Fondly known in Colorado Springs as the Castle on the Hill, the Union Printers Home has a long history of caring for people. Built in 1892 by members of the International Typographical Union to offer specialized health care to their union members, the facility today serves the general public with a multitude of services, including assisted living, nursing care, rehabilitation and hospice.

In 2012, extreme hail damage made it essential to replace the roof on the structure, which is a State of Colorado Historical Site. Interstate Roofing removed more than 50-year-old asbestos tiles on the roof and recommended polymer roofing tiles that complement the existing architectural style. “Considering the age, condition and historical value of the structure, we needed a roofing product that could work with the building while ensuring longevity to the structure,” says Scott Riopelle, owner of Interstate Roofing in Colorado Springs.

Although Riopelle was confident in the selection of the roofing product, there were many challenges for this project. The 50-man crew first had to complete the safe removal of the existing asbestos-laden tiles.

“We had to erect scaffolding 5-stories high to access the roof,” Riopelle says. “Due to the 12:12 roof pitch and the multiple turrets on the structure, building containment areas and debris removal were extremely dangerous. During the entire process, we performed continuous air-quality testing to ensure the safety of the home’s residents, staff and our crew.”

The team worked through the winter months and experienced continuous rain, wind and snow. Riopelle explains: “This means we had abatement processes, plywood redecking, dry-in and loading crews, heavy-equipment contractors, installers and supply companies all working in extreme-weather conditions. For this project, logistics and coordination went minute-to-minute.”

The temporary removal of the large historic clock on the front of the Union Printers Home created the next challenge. Because of its age, there was concern for the clock’s condition. Staff at the home asked that the hands of the clock not be moved; they were permanently set at 8 o’clock to represent the union’s efforts in the past to encourage an eight-hour workday.

Reroofing the turrets on the project was easier because of the Turret Package from DaVinci Roofscapes. Interstate Roofing provided DaVinci with four dimensions (the distance from the peak to the turret to the edge of the drip cap, the turret pitch, the turret cap length and the coursing exposure). From that information, Turret Packages were created, including the starter tiles, numbered field bundles custom-engineered for each course and a turret map diagram to guide the team through installation.

The three-month project had a gratifying outcome for Riopelle and his team. “This was a once-in-a-lifetime project,” Riopelle says. “Although we’ve completed projects much larger and more complex, this one was special because of the history associated with the Printers Union Home and the importance of the facility to the community.”

Interstate Roofing embraced the challenge of tying the old historic structure in with the new technology of the polymer slate products. “The results are amazing. This historic structure has a new life thanks to this roof,” Riopelle observes. “And since the roofing tiles are impact- and fire-resistant, there’s greater peace-of-mind for the staff and residents at the Union Printers Home.”

AEP Span is now offering its metallic-coated and pre-painted architectural metal panels with graffiti-resistant coating systems.

AEP Span’s factory applied graffiti-resistant coating systems consist of a three-coat system including a primer, a color coat, and a graffiti-resistant clear coat in a low to medium gloss and a high gloss. These coating systems are available in all AEP Span paint systems.

The graffiti-resistant coating systems work as a barrier of protection over a steel surface and is formulated to work with PPG’s DuraPrep Prep 400 graffiti remover. The coating systems prevent most graffiti material from gripping or shadowing the surface, which allows the field applied DuraPrep Prep 400 graffiti remover to wipe away graffiti. If an AEP Span architectural metal panel is spray-painted, graffiti can be eliminated by applying the graffiti remover directly to the stain, allowing it to sit for 10 to 60 seconds, then wiping it with a clean cloth or scrubbing it with a nylon brush. Most stains can be removed in 10 minutes or less.

Other graffiti that can be removed include paint overspray, pen and marker ink, lipstick, scuff marks, tape residue, bugs, tar, and many other substances that mar the appearance of steel building panels.

ROOF MATERIALS

The domed roof required about 6 tons of 20-ounce Flat-Lock copper. W.A. Lynch Roofing sheared 4,000 individual tiles to approximate dimensions in its sheet-metal shop, and a makeshift sheet-metal shop was set up on top of the scaffolding to complete the final measurements and exact cuts.

ROOF REPORT

The University of Virginia was founded by Thomas Jefferson in 1819. Jefferson modeled his design—presented to the university board in 1821—after the Pantheon in Rome. Although he died in 1826 while the Rotunda was still under construction, the stunning building housed the university’s library as Jefferson envisioned.

The rotunda renovation is a two-phase project, and roofing work was part of Phase 1. The roofing team believed seven months was adequate to complete the job; the university, however, requested it be complete by April 2013 so scaffolding would be removed in time for the commencement ceremony. That gave the team a four-month timeline.

The domed roof required about 6 tons of 20-ounce Flat-Lock copper.

Tom McGraw, executive vice president of W.A. Lynch Roofing, explains: “This was just short of impossible even if it wasn’t winter. But as a graduate of UVA, I recognized the basis of the request and agreed to it. So we doubled the manpower and went to a 10-hour day, seven-day a week schedule. We divided the roof into four equal quadrants, each separated by an expansion joint and put a crew in each area working simultaneously with the other three. We also added support personnel in our sheet-metal shop, as well as runners to keep the flow of material to the job site on schedule for the sheet-metal mechanics. In the final analysis, we made the schedule and completed our work within the owner’s request.”

The roofing project was essential because of rust on the previous terne-coated metal roof. It was determined the rust was caused by inadequate roof ventilation that created condensation on the underside of the metal roofing. Ventilation was lacking because of a Guastavino tile dome that was installed in 1895. The condensation was addressed by installing a concealed venting system at the intersections of the treads and risers at the seven steps in the roof, as well as at the top of the dome below the oculus. “Heated air has low density so it will logically rise creating natural convection,” McGraw notes. “This convection creates air movement below the roof and minimizes dead air spaces and the potential for condensation. The key to this is ensuring that you size the ‘intake’ venting similar to the ‘exhaust’ venting so that air will flow in an unrestricted fashion.”

Reroofing a dome can be a challenge, and determining how to keep the interior and its priceless valuables dry required some ingenuity. McGraw invented a tarp that he compares to a hooped skirt to keep the space watertight. The roofing crew cut trapezoidal sections of EPDM membrane and installed them from the bottom to the top of the dome. This skirt-like tarp was configured out of eight pieces at the bottom, six at the midpoint and four at the top. The maximum cut sizes for each level were determined using a computer drawing. Creating the EPDM covering in sections made the tarp easy to handle and remove. “If we seamed it all together or made it in less pieces, the guys wouldn’t have been able to lift it,” McGraw adds.

The tear-off process involved removing the painted metal panels according to lead-abatement standards; the panels were cleaned offsite to maintain the integrity and safety of the job site. A new wood deck was installed on furring over the tiles. This was covered with 30-pound roofing felt and red rosin building paper followed by the new copper roof.

Each piece of copper was tinned and folded before being installed. This process was necessary because of the lack of symmetry on the building. McGraw recalls: “Because this building is almost 200-years old, you have to recognize that not everything is as true and square as one might hope. There are seven steps that circle the base of the dome, and each tread and riser changed in height and width all the way around the building.”

This is the fourth roof for the Rotunda. The first was a tin-plate roof designed by Thomas Jefferson; the second was copper that was a replacement roof after a fire in 1895; the third roof was painted terne-coated steel from 1976; and the current roof is 20-ounce Flat-Lock copper that will be painted white. The decision to select copper was based on cost, durability and historic appearance.

Phase 2 of the project began in May, and the Rotunda will be closed for repairs until 2016. At a price of $42.5 million, utility, fire protection and mechanical upgrades will be made, as well as a Dome Room ceiling replacement and construction of a new underground service vault. The roof also will be painted white, and leaking gutters will be repaired during this phase.

AEP Span Installs Solar Panels on Fontana, Calif., Facility

When the decision was made to replace a 20-year-old roof at the AEP Span Fontana facility, it was a perfect opportunity for the organization to reaffirm its commitment to the environment and the use of renewable energy.

“We are serious about our environmental footprint,” said John Cross, President of AEP Span, a division of ASC Profiles LLC. “Solar power is an excellent form of alternative energy with numerous environmental benefits. In fact, this is our second location where we have installed solar panels.” The West Sacramento corporate headquarters was the first location to have solar carports and roof arrays installed. In ASC Profiles’ corporate offices, a monitor was installed that provides real time cumulative results of the total energy generated and total CO2 offset for both the corporate headquarters and the AEP Span Fontana facility.

The new 439.2 kw solar energy system is a fixed-tilt, roof mount solar array that was installed on AEP Span’s architectural standing seam Span-Lok hp metal roof. With the solar panels now operational, the anticipated results the AEP Span Fontana facility will offset annually is 553 metric tons of CO2, which is equivalent to removing 111 cars from the road, saving 200 tons of waste from landfills, or providing electricity for 74 houses. The expected life of the system is 30 years.

AEP Span has partnered with a variety of customers providing solar structures in the solar industry. Moreover, AEP Span offers a wide range of architectural standing seam metal roof panels that are a perfect complement to roof mount solar panels for the commercial and industrial market. AEP Span standing seam metal roof panels include Design Span hp, Multilok-24, Klip Rib, SpanSeam, Span-Lok hp, and Curved Span-Lok.
