Re-Roofing a Planetarium Under the Stars

Photos: Versico

The James S. McDonnell Planetarium is a St. Louis icon. Located in Forest Park, a 1,300-acre public park, the planetarium is the main attraction at the Saint Louis Science Center, one of the few free nonprofit science museums in the country. It serves more than one million people each year. Opened in 1963, the planetarium features one of the world’s best opto-mechanical start projectors, which projects a 360-degree view of the constellations in the night sky onto its domed ceiling.

The giant, white structure is hard to miss, but its roof is hidden from view for those on the ground. The low-slope roof system and penthouse are nearly invisible behind a large, bowl-shaped parapet. The existing roof was saturated with moisture and was starting to develop leaks, and the planetarium’s dome-shaped screen and multimillion-dollar projection system could not get wet.

The Problems

Bade Roofing was just finishing up a re-roofing project at a Science Center warehouse when the company was called in to take a look at the planetarium roof. According to Dave Bade, president of Bade Roofing, and Drew Bade, the project manager, the company determined a total roof replacement was required. They also identified some key challenges.

A crane was used to lift material to the roof and remove debris.

The 4,000-square-foot roof is unusual; it’s perfectly round, yet slightly bowl-shaped, with round penthouse in the center. The unique shape would make it difficult to design a tapered insulation system, flashings, and terminations for the 30-year project. Another difficulty was posed by the concrete step-offs located under the existing roof. There were no dimensions on the original plans, so creating the tapered insulation layout would be especially tricky.

The schedule was also complicated, as the planetarium would remain open throughout the construction process, hosting daily educational presentations for schoolchildren, as well as special events and exhibits. Work couldn’t take place during business hours.

“We had to work at night, craning stuff up there with big lights,” says Dave Bade. “The good thing was the guys couldn’t fall because they couldn’t go anywhere; the roof had an eight-foot wall around it. The safety plan was easy, but the tapered design was tough.”

The Proposal

Bade Roofing decided to go with a SureMB 120TG Base Ply as a temporary roof to ensure the equipment inside the building would be protected throughout the tear-off and installation process. “It was a secondary line of defense that allowed us to remove the entire roof all at once and not have to rely on tie-ins from the old roof to the new one when the crew started and stopped each night,” Drew Bade says.

The existing roof of the James S. McDonnell Planetarium was removed and replaced with a fully adhered 90-mil EPDM system from Versico.

The temporary roof allowed the company to accurately measure the existing roof for the tapered insulation design. “This is another reason we decided to use the SureMB 120TG; it allowed us to really see what was going on with the tapered and make adjustments prior to ordering,” notes Drew Bade.

The roof specified for the final phase of the project was a 90-mil VersiGard EPDM fully adhered system manufactured by Versico. “The Science Center and the architect both have a history of using EPDM on their projects because they’ve had a lot of success with it,” says Drew Bade. “And with the uncommon design and shape of this roof, EPDM was perfect to mold into all the unique angles and it did a good job conforming to the many curves of the building. We used a 90-mil EPDM to get the 30-year warranty the Science Center wanted and for the overall longevity of the roof.”

The Process

Once the crane and light towers were in place, crews began the loading and tear-off process. Crews accessed the roof through a window of the penthouse, but material had to be lifted in place with the crane. The typical workday began at about 5 p.m., and crews worked until 2 or 3 o’clock the next morning.

“We started by priming the concrete deck with CAV-GRIP 3V,” says Drew. “Then we installed the SureMB 120 TG Base Ply.”

The insulation was adhered in Flexible DASH low-rise adhesive. Crews installed a base layer of 2-inch SecurShield polyiso, which has a special facer, followed by a layer of tapered SecurShield polyiso. The drainage areas needed exacting care. “The drains were down in a concrete sump,” says Dave Bade. “We put the drawing right on the roof and cut out each of those sections. It was like cutting a pie into 50 pieces.”

Crews then installed Securock cover board, followed by the 90-mil VersiGard EPDM. “The EPDM did a great job conforming to the building’s angles and curves,” says Drew Bade. “We adhered the EPDM with Versico’s standard Bonding Adhesive because it’s got a long track record and it works.”

Once the tapered insulation was in place, the membrane installation was pretty straightforward, although the circular roof area posed some challenges with the details. “The counter flashings and terminations were kind of tough because everything had to be pre-bent to that radius,” Dave Bade notes. “It wasn’t a tight radius, but everything had to be pre-formed to that exact radius so you could keep constant compression on that membrane.”

The Professionals

The new system qualified for a 30-year warranty. “One of the main benefits of a Versico system, from a contractor perspective, is the support from Versico’s tech reps,” says Drew Bade. “It’s second to none; they make sure the job’s done right and they’re there every step of the way.”

The work was meticulous, and Bade Roofing’s experienced crews took great care to get it right. “The artistic part of it is the roof itself. It’s a shame that no one will ever see it,” says Dave Bade. “We did the work at night, so no one even saw our trucks.”

It’s a satisfying accomplishment to re-roof an iconic structure, even if no one sees you do it. “We really wanted to do this job,” says Dave Bade. “It meant a lot to us because we try to do things that are out of the ordinary. After being in business for more than 60 years, you like project like this because you get to show off your talents. And the men like stuff like this; the ones who got to work on this project, it really meant a lot to them. They are true professionals.”

Roof of Hong Kong’s Premier Yacht Club Gets a Major Facelift

Photos: Green Tech Insulation Systems (GTIS)

Set within a premier marina and home to some of the region’s largest luxury yachts, the Gold Coast Yacht and Country Club is an opulent leisure retreat for the who’s who of Hong Kong. Nestled along the South China Sea, the club offers stunning oceanfront views and an enviable set of amenities and attractions for its members and visitors.

But even the most picturesque and well-located of properties is subject to the elements. A subtropical region, Hong Kong’s weather pattern includes an annual typhoon season spanning May to November when periodic downpours, tropical storms, and heavy winds are more commonplace. In fact, this weather is directly responsible for the necessary, recently completed retrofit of the yacht and country club’s roof.

Prior to retrofit, the existing 38,000-square-foot roof was comprised of terracotta tile, including grout lines throughout. With both a flat deck and a pitched deck, none of the tile work was actually waterproof — far from ideal in moisture-laden Hong Kong. In 2018, after several years in operation, the lack of waterproofing had led to significant leaking throughout various portions of the roof. The club ownership recognized the necessity of restoring the roof to prevent additional costly structural damage. That’s when Green Tech Insulation Systems (GTIS) was called in.

Gold Coast Yacht and Country Club in Hong Kong underwent a complete roof restoration and then added solar panels as part of a complete energy overhaul.

A Hong Kong-based roofing and insulation contractor specializing in innovative sustainable solutions, GTIS was faced with some serious challenges. The new roof system obviously had to seal and waterproof the facility and GTIS recommended spray polyurethane foam (SPF) roofing to the club for its abilities to do both. Additionally, SPF is a lighter weight solution that may be applied directly overtop an existing roof, eliminating the costly and time-consuming removal of the older tile roof.

But the regional weather and rains complicated the installation itself. Either rain or extreme humidity was present during at least half of the installation timeline, making it difficult to dry out the substrate prior to application of the SPF roof. To ensure proper adhesion to the substrate, GTIS utilized Lapolla Thermo-Prime. The single-component, water-based acrylic primer promotes adhesion of spray foam roofing to a variety of substrates.

The roof also included interior gutters, many of which were experiencing moisture intrusion through cracks. For this issue, the four-person GTIS crew used a roof torch to dry out the concrete. The GTIS team also utilized silicone for the repair and refurbishment of these gutters.

The spray-applied Lapolla spray foam system was installed over the existing tile roof, and a custom color topcoat was applied to match the previous color.

GTIS spray-applied Lapolla FOAM-LOK 2800-4G, a spray foam system notable for integrating the earth-friendly Honeywell Solstice blowing agent, which eliminates ozone depletion impacts and dramatically decreases global warming potential over older spray foam roofing systems.

“Spray foam roofing is the right product to be deployed in Hong Kong because of its superb performance in the face of our regular and somewhat harsh weather patterns,” says Chris Brazendale, managing director of GTIS Asia Limited. “The combined ability to seal, waterproof, resist high winds and reduce energy demands are major selling points here.”

Robert Grant, Icynene-Lapolla’s field service representative based in Arizona, attended a portion of the installation to provide educational training to some of the newer GTIS crew installers.

“We pride ourselves on the resources we provide to our contractors and the training I provided onsite is a good example of this,” says Grant. “When weather caused delays on the project, I also got into full gear and laid down a good portion of the roof to help GTIS meet the project timeline.” Grant himself is also a trained installer.

Club management shared its appreciation of the installation timeline being met. “From start to finish we have been impressed with the GTIS team,” says Robert Kawai, general manager of the Gold Coast Yacht and Country Club. “The project completed quickly and work was done with minimal impact to the Club’s operations.”

Energy-Saving Strategy

The owners of Gold Coast Yacht and Country Club were looking for a complete energy solution for their upscale destination. In addition to the spray foam, which guarantees significant long-term energy bill savings, they also sought a renewable energy system. Once the roof retrofit and coatings were successfully applied and in place, the owners also engaged a solar contractor to install a robust photovoltaic system. Installation of the photovoltaics took place over a one-month timeframe.

“The Hong Kong government recently introduced an initiative to provide power directly back to the grid, which the owners of the club are participating in,” notes Brazendale. “Additionally, the longer-term plan will be to install batteries to capture the solar power and to offset energy demand at the facility. An added benefit of the batteries is assurance to the owners and managers of the facility that power will be accessible to the club, even if a storm or another event affects the grid.”

A key requirement of the client was to maintain and enhance the attractive appearance of this upscale facility. To that end, the GTIS and Lapolla teams worked with the club ownership to develop custom color coatings designed to match the original tile roof, and these were applied to the completed SPF roof. GTIS recommended Lapolla THERMO-FLEX 1000 elastomeric coating for the roof and GE Enduris 3500 silicone coating for the roof perimeter.

“The custom color topcoat really helped us retain the overall original appearance of the roofs, which was important to us” says Kawai.

In addition to providing a protective layer over the spray foam material which protects it from UV rays, debris and the elements, the coatings also stand up to the humidity present at the ocean-adjacent site. The coatings also protect against biological growth, which is key as roof surfaces under solar panels typically do not dry as quickly.

“The owners are extremely proud of the retrofit,” notes James Cooper, operations director of GTIS. “With regular care and maintenance, the new roof is expected to last for decades. This combined SPF and solar roofing system is a sustainable investment in the Gold Coast Yacht and Country Club that will provide valuable ROI for a significant number of years to come.”

“We are really looking forward to the benefits of a watertight roof and lower cooling costs and are so happy with the team and SPF and coatings products we selected for the club,” adds Kawai.

Sports Facility Highlights the Versatility of Insulated Metal Panels

Sports facilities are unique environments that face varying environmental conditions from both within and outside the structure. In evaluating building materials, client and builder seek proven solutions for meeting environmental requirements, codes and long-term durability without forsaking the art of design.

Enter the new Boston Sports Institute (BSI), a 130,000-square-foot multi-use recreation facility in Wellesley, Massachusetts, a suburb of Metro West Boston. A collegiate town and activities hub for surrounding residential communities, Wellesley lacked a professional-grade sports facility. Featuring two NHL ice arenas, a synthetic turf field, indoor track, repurposed 2012 Olympic trial pool, warm-up pool, sports rehabilitation area and strength training facility, this $23.3 million complex was completed in July 2019. Centered on a public-private partnership model between the town and the management company Edge Sports Group, BSI prioritizes ice and pool time for local schools who previously traveled to professional facilities. It is also rentable for private organizations and sports groups.

Barnes Buildings & Management Group installed approximately 58,000 square feet of insulated metal panels from Metl-Span.

“We were committed to using insulated metal panels from the earliest design stages, both for its performance and design flexibility,” states Kevin Provencher, AIA, LEED AP, Director of Architecture at the design builder, Dacon Corporation. “We have a lot of history with this type of product on a variety of building types. It is an effective solution for multi-use facilities with variable environmental requirements. Both ice rinks and natatoriums have high moisture loads, but the ice rink’s temperature will be maintained at 55 degrees Fahrenheit while the pools are at 82 degrees. It’s an ideal wall system for a facility with demanding environmental needs.”

Provencher notes insulated metal panels (IMPs) provide a total wall system that incorporates a continuous insulating layer with control layers for weather, air and vapor barriers. “It helps that we partnered with a quality metal building builder,” Provencher says. “Collaboration was key to this project’s success. Selecting the right details and sharing responsibility eases the burden on the designer.”

Barnes Buildings & Management Group Inc. of Weymouth, Massachusetts, a Metallic Building Company dealer, installed the insulated metal panels from Metl-Span as well as the engineered metal framing system. Tony Barnes oversaw the erection of the metal framing and challenging installation of 58,000 square feet of insulated metal panels. Tim Allison, the Vice President of Project Management at Barnes, oversaw project administration.

Barnes Buildings & Management Group installed approximately 58,000 square feet of insulated metal panels from Metl-Span.

“We have a mixture of panel types in multiple colors that run in two orientations,” Allison says. “When we have just one type of panel and one color, we simply unwrap the bundle and install continuously. With multiple colors, you must spread out bundles so we can access the panels in the order needed. With this site, we didn’t have much room, so it was tricky. We paid close attention to the drawings and details to ensure correct installation.”

Allison says Barnes Buildings erects a lot of structures using engineered metal framing systems and IMPs. He’s noticed an architectural trend is using mixed colors and panel orientation.

Metl-Span’s Smoke Gray, Polar White and Sandstone were installed to create an eye-catching aesthetic. “Our client wanted a strong visual impact on the north façade facing the state highway,” Provencher says. “When passing other commercial buildings commuters notice this vibrant design featuring vertical and horizontal panels. Tim Allison and Marty Barnes provided valuable input, influencing the final outcome.”

There are several unique details to BSI, including a parapet on the gable end of the building above the pool. It starts low at the eaves and grows to 3 feet at the peak to hide rooftop equipment. Barnes Buildings also installed an accent band near the top of the building, a single-skin metal panel that continues horizontally from the windows. The 7.2 Rib panel from Metl-Span is 36 inches wide with ribs that are 1-1/2 inches deep.

The roofing for more than 75 percent of the building is a double lock standing seam from Metallic in bare Galvalume. The roofing above the pool is a bare Galvalume insulated metal panel, Metl-Span’s CFR system. It starts approximately 35 feet from the roof peak, so the top section of roofing is standing seam. At the transition to where the IMPs are above the pool, the roofline drops 1 foot. The interior skin on the roofing and wall IMPs in the pool area are coated with Valspar’s Flurothane IV, a finish formulated to protect in exceptionally harsh environments where chemical corrosion protection is needed.

“It’s all things we’ve dealt with on other projects, but there’s a little bit of everything on this one,” Allison says. “It’s a special job and a visually appealing project. The IMPs are ideally suited for our New England climate. When used as walls and roofing, they provide excellent continuous insulation on any building.”

Roofing a Resort in Paradise Took Great Design and Better Planning

Photos: Timbers Kauai

The Hawaiian Islands epitomize paradise with sandy beaches, crystal clear waters, warm days and balmy nights. Some are blessed to call the islands home, while others are lucky visitors. Both groups come together at Timbers Kauai — Ocean Club & Residences at Hokuala, an oceanfront destination nothing short of spectacular.

Opened in June 2018, Timbers Kauai exudes luxury island living. Located on Kauai’s picturesque southeast coast, the destination offers short- and long-term residents breathtaking unobstructed views of the Pacific Ocean and Hau’pu mountain range as well as immediate access to an unparalleled shoreline.

The design aesthetic of Timbers Kauai is inspired by the naturally distinct Hawaiian paradise surrounding it. All materials and finishes were deliberately selected for the richness and longevity they provide, from the cladding and windows, to roofing, luxe interior finishes and lush landscaping. Elements combine naturally, providing seamless easy connections between indoor and outdoor spaces.

“Key Hawaiian-inspired design elements were incorporated into the public indoor and outdoor spaces and main lobby,” says Gary Ross, director of architecture for Timbers Resorts. “Examples include the wave patterned fascia panels, nautical inspired backlit entry panels and the lobby’s Kappa inspired floor tile patterns.”

The Timbers Kauai features Hawaiian-inspired design elements throughout. Materials and finishes were selected for the richness and longevity they provide.

When considering roofing options for the resort, architects aimed for a durable, resilient material that complemented the sophisticated island design theme. They ultimately turned to Irvine, California-based Boral Roofing, specifying Saxony 900 Slate Appalachian Blend, a high-performance concrete roofing system with earthy stone hues replicating the natural look of real slate.

Since concrete tile is a high-quality, durable roofing solution that lasts much longer than some other competing roofing options, it is an ideal solution for the resort. The low maintenance tile also allows for localized repair areas should damage ever occur.

Sustainability is a major selling point of the concrete roof tile. Manufactured using naturally occurring and abundant geologic materials, the tile incorporates no chemical preservatives and is 100 percent recyclable at the end of its life on the roof. Concrete tile also provides the resort with substantial energy efficiency benefits, rendering significant reductions in the ongoing energy costs associated with heating and cooling the property as the seasons shift.

Fighting Unpredictable Weather

Another core consideration in the selection of the roof was storm resistance. The subtropical weather on Kauai can be trying for a roof. Hot, humid weather is common and torrential rainfall, fierce wind and hail occur as well. To protect the resort from these harsh weather variables, the architects sought a roofing material able to withstand the elements. Boral Roofing’s tile not only provided a complementary aesthetic, but also the weather resistance attributes required on Kauai.

Architects chose a high-performance concrete roofing system from Boral Roofing that replicates the look of natural slate.

 “We were able to specify a product that not only met the stringent wind and rain conditions of building in Hawaii, but also provided the style and elegance required of this project,” says Chris Ridings, partner at Poss Architecture + Planning of Aspen, the design firm retained by Timbers Resorts for the project.

Concrete roof tile also notably scores high in fire resistance. The Timbers Kauai roof is non-combustible, helping prevent ignition from occurring. The tile offers a Class A fire rating, the highest fire resistance rating for roofing.

Challenging Installation

Those involved in construction in Hawaii understand shipping can be a challenge. Many building materials must be delivered from the mainland. With most projects on strict timelines, delays in shipping can be troublesome and even costly. Thus, it is important that logistics, lead times, packaging, and fulfillment of orders are correct. With the roof installation, these factors came in to play.

Installation of the roof was led by Honolulu Roofing & Waterproofing, one of Hawaii’s first-established roofing companies. A project comprising three large buildings and 600 squares, the installation occurred over a three-month period. “We had to deal with adverse weather, primarily rain, but also hurricane warnings,” says Dan Jaeger, vice president. “Kauai didn’t end up getting hit with a hurricane, but because of the warnings, the materials already in transit had to return to their shipping origin and then be re-shipped. It took a bit longer than we would have liked.”

Despite weather delays, the Honolulu Roofing team completed the installation seamlessly once it got started. Jaeger points out that Boral Roofing was onsite during installation and contributed to the project’s success. “It’s really great to see a manufacturer present putting that level of effort into providing guidance during an installation,” Jaeger says.

The roof included all Boral components, but the attachment used for this project was the Polyfoam instant set adhesive, which is compatible with Boral Tile Seal underlayment.

Honolulu Roofing was able to install more than 580 squares of roof tile using one crew of eight men, with each member assigned a specific task on the roof, all overseen by Jaegar. He flew in daily from Honolulu before sunrise to make sure the job ran smoothly, even getting in a morning walk to the job site for exercise.

Honolulu Roofing also provided waterproofing for the low-slope portion of the project as it was critical that the roof tile installation tied into the low slope system properly. All told, the installation of the roof tile was completed ahead of schedule despite weather-related shipping delays.

Built to Entice and Endure

Timbers Kauai – Ocean Club & Residences at Hokuala is designed to offer an unparalleled experience for those who visit. Built from rich materials that last, the resort encourages luxury island living along a breathtaking stretch of coast. The island retreat offers residents and visitors alike a thoughtfully curated collection of services including access to a full-service restaurant with progressive approach to farm-fresh Hawaiian food, an oceanfront infinity-edge swimming pool, a separate ohana pool with a beach entry, and water features that form the heart of the resort. These are just a few of the onsite amenities set within the quality-crafted resort built of exceptional materials. No doubt, Timbers Kauai is designed to endure.

These days, when trains stop at the Wyandanch Station in Wyandanch, New York, they’re traveling through a completely renovated, eye-stopping facility. Atop that train station can be found a new composite slate roof.

The state-of-the-art location is the most recent new train station constructed by the Long Island Rail Road (LIRR). The 2,800-square-foot structure is topped with 5,000 square feet of DaVinci Single-Width Slate roofing in a Castle Gray color.

As part of the Double Track Project, the LIRR built two new 12-car-long platforms that include a snow melt system, a pedestrian overpass with elevators, new stairs, new canopies and new platform shelters. The interior of the station features Terrazzo tile floors, a wood-paneled ceiling and chandeliers. Some 4,200 people use the train station each day.

The new Wyandanch Station is part of a revitalization effort called Wyandanch Rising. A highlight was the construction of the new train station and adding a second Long Island Rail Road track running through the Wyandanch area. The LIRR partnered with the Town of Babylon and Suffolk County in the site location and design of the new Wyandanch Station.

As construction progressed on the train station, Ashlar Contracting was brought in to work on the project and install the roof. “The roof is a key architectural element on the design of this station,” says Christopher Monahan, owner of Ashlar Contracting in Bohemia, New York. “The DaVinci composite slate was very easy to install and makes a large visual impact on this structure. The product looks like real slate and complements the entire look of this train station.”

Opened in September of 2018, the Wyandanch Train Station is receiving positive reviews from daily users and the general public. “We get compliments all the time on the train station,” says Peter Casserly, project manager with Bay Village Consultants Inc. out of Amityville, New York, developer of the site. “The entire facility has been well received by the immediate community and all those who utilize it. The roof plays a vital visual role in the train station. I’m pleased to say we’ve had no issues with it and look forward to it providing both shelter and beauty for the structure for decades into the future.”
