The undulating profile of the Marco Polo Condominiums has been a fixture on the skyline of Honolulu since 1971. But even though the building still looks striking after 40 years, there was trouble in paradise - in the form of a leaky roof. The existing roof had its share of problems, including asbestos and numerous penetrations that had popped up over the last four decades. Charlie Beeck Jr., the president of Tropical Roofing and Raingutters Inc. in Honolulu, knew that the job could be handled smoothly if the right system were specified.
Beeck moved to Hawaii in 1977 and entered the roofing industry almost by default. “It’s kind of a funny story,” he said. “I sold solar water heating door-to-door to homeowners. They’d say, ‘I can’t afford solar - I need a new roof.” I asked one guy, ‘If I could get you a new roof and a solar system at the right price, would you buy them both?’ He said yes and did, and I got two commissions.”
The presence of asbestos meant a licensed abatement company had to handle its removal. “An abatement company removed the old roof due to the asbestos, and we followed behind them and dried it in,” Beeck said.
The Roof SystemChallenges on the 300-square project included limited roof access. A crane could not be used to load the roof, so getting material up to the roof was a chore. “Everything had to be taken up the elevator and then up one flight of stairs,” said Beeck. “It was very labor intensive. We brought material up every day.”
There were also numerous penetrations, which Beeck acknowledged were the toughest part of the project. “There’s more equipment up there than anyone can imagine,” he said. “Air conditioners, air handlers, vents - it was jam-packed with equipment.”
The new system specified included membranes from Polyglass USA, Inc., beginning with its Elastoflex® SA V FR base sheet. Polytherm® 3.1-inch iso insulation board was adhered with Dow InstaStik adhesive to achieve an R value of 19. Half-inch Securock served as the cover board, while quarter-inch DensDeck Prime was used on the vertical curbs. The system was then topped with one ply of Polyglass’ Elastoflex SA V FR base, a self-adhered, SBS modified bitumen base sheet that features patented ADESO® Dual Compound Technology. Polyflex® G FR, a polyester-reinforced, APP mod bit granulated cap sheet, was then torch-applied to finish the job. It is available in ten colors, and white was chosen for this project.
“Because of all the penetrations, this system was a very good choice,” Beeck said. “It was easy to flash. It’s a very flexible product and it was easy to move around penetrations. It works very well around corners, up walls, in situations like that.”
The self-adhered base sheet also saves time, Beeck noted. “It goes pretty fast as long as you’ve got it lined up right.”
Watching the SkiesWork spanned the month of February, which can mean rough weather, even in Hawaii. “Of course, safety is the biggest concern on every job, but the building lies in a little rain belt, so the weather was also a concern,” Beeck said. “We did this job over the winter, which is our rainy time of the year. We had strong winds and a lot of rain. We watched the weather reports in order to set up the schedule. We got on the computer every day to check it out.”
Luckily Beeck and his crews are used to working in those conditions. “It rains almost every night, and you have to get it dried off before you can get to work,” he said. “We used blowers to speed the drying process. The Hawaii hot sun also helps a lot.”
The increased insulation and the reflectivity of the roof surface will also help reduce the building’s utility bills, noted Beeck. “It will definitely be cooler, and they’ll save on air conditioning costs.”
Beeck expressed thanks to his Polyglass representative, Howard Meechan, RRO, for his help with the project. “We work with Polyglass a lot, and Howard Meechan is very knowledgeable about the roofing industry. He did all the inspections and had all the specifications written so we could give them a 20-year warranty.”
“I’m very happy we went with Polyglass,” he concluded. “The boys work with it well and they like it. It was the correct product for the job.”
