There's been a lot of water over the roof since 1981, when The Roofer Magazine (as it was then called) premiered. With artistic covers, human interest stories, the latest news and expanded coverage of new innovations, the magazine helped usher in a new era for the roofing industry. Emerging at about the same time as a membrane known as single ply, the advent of The Roofer was another indication that the image, marketing and selling of roofing was about to change forever.
As part of Roofing Contractor's 25th anniversary, this is a glance back at some innovations, stumbles and events that give perspective to our current industry. There are many stories out there, and it's a challenge to dig so far back with all of the change that occurs, but here are a selection of updates and flashbacks on events that have shaped our industry. As we find more news about those that have graced these pages, we hope to keep readers informed with future updates on the projects, people and products profiled in the pages of Roofing Contractor.
Just VentingThe first issue, a combined September/October issue which launched in 1981, discussed a new approach to a problem that still inspires debate and controversy: ventilation. Parker and Mudgett, and architectural firm in Fort Myers, Fla., capped a square residential house with vent that went around the entire top third of the roof. It was an effort to release heat and moisture from the crawl space in the days before double-paned low-E windows, radiant barriers and house wraps.
He has used the technique several times and often puts the air conditioning units in the crawl space on pitched roofs. The insulation is part of the roof deck as air enters the soffits, travels through the raised decking and out through the vent. Even though roof ventilation is part of the building code, there is still debate in Florida about circulating hot, humid air under the roofing system. The private home featured in the article still stands, albeit with a few additions.
Time to ReflectIn 1982, advertisements in The Roofer touted something new called a ceramic roof coating. The product was inspired by roof paint - something common in the South during the 1950s and 1960s - and was designed to improve thermal performance with the properties of ceramic granules. The space shuttle that would later launch from Cape Canaveral featured ceramic tiles on the bottom to insulated the craft from the intense heat during re-entry into the Earth's atmosphere.
It turns out that the product's originator, Richard Ziebarth, was reading about those tiles when he had a "eureka" moment. Working with a chemist in the late 1970s, he formulated a white, durable coating that also acted as insulation. According to his son, Dave, the earliest use for the product was to insulate steam pipes, but customers in that market didn't buy much product. So the roof-painting contractor converted his fleet of trucks and built a plant in Inverness, Fla.
"We were going to be in any business that this ceramic technology would work on," says Dave Ziebarth, president of Insulated Coatings Corp. "I don't even think there was a reflectivity test back then. Emissivity was not something people said in 1982."
An early niche market centered on mobile homes, but the market expanded to include restoration of any number of roofs. In addition to avoiding the cost of a tearoff, the energy savings from a reflective roof were being recognized in the 1990s through Energy Star and other programs. Now building codes and tax breaks are feeding a huge growth in reflective coatings. Ziebarth has developed reinforcements and primers for coating EPDM roofs that fix seams, bring the thickness to 60 mils and make the coating reflective.
The market for reflective roofing has transformed from patch jobs into high-performing systems with 10-year guarantees. Benefits include saving money, energy and landfill space. In order to better promote the concept, the Reflective Roof Coating Institute held its first meeting at the International Roofing Expo in February. Even after all this time, Ziebarth is finding new applications for a bright idea.
"We're just getting started," he says. "Now that everybody is buying into it, we have to pay attention to quality in the industry. We've got roof consultants bringing us business. It's remarkable what we're able to do for the end user."
Fallingwater (Inside)Famed architect Frank Lloyd Wright had numerous strengths, but roof details weren't one of them. His buildings' reputation for leaking roofs even reached his masterpiece, Fallingwater. Constructed in western Pennsylvania, this bold, angular construction was built over Bear Run creek. The flat concrete decks provided excellent views and dramatic lines, but were a bear to waterproof. Workers involved in the construction of the original house report mixing the concrete by hand and then shoveling it into forms, leaving the rounded tops on the parapets crooked but modern looking. The original roof was a built-up roof (BUR).
In February of 1988, Roofer reported on a 60 mil EPDM membrane by Goodyear being installed. Several areas received pavers and lead flashing. Ten years later, the pottery terrace was reroofed with an inverted roof membrane system (IRMA) by W.R. Grace. The two-ply system with rubberized asphalt mastic was given a drainage mat to direct moisture towards newly installed drains.
Focusing on Quality ControlWhen all tools were hand-powered and BUR was king, roofing was more of an art than a science. Sometimes three or four layers of some decent asphalt or coal tar can make up for shortfalls in design, training and even materials. But when oil prices shot up and the asphalt quality came down, single ply came in with a vengeance. Quality control became a mantra as fingers were pointed and new roofs were cut open to look for any voids between felts.
Endorsements trickled in over the years until, in 2001, the NRCA and the Asphalt Roofing Manufacturers Association (ARMA) worked together to produce a joint document that spells out standard practices needed to achieve a quality BUR or modified bitumen system. The booklet was released in 2004.
SIDEBARS1982- The March/April issue included a feature article on using horses to tear off an existing BUR. They were used after union roofers refused to cross a picket line. The ponies were trained to pull 4,000 pounds on a sledgeboat and could even perform tricks. The issue also featured article on W.R. Grace's refusal to warranty BURs using fiberglass felts over Zonolite, a lightweight concrete deck. Organic and (with some limits) asbestos base sheets and felts could be still used.
The Time Capsule
1982- The July/August issue included the first listing of single-ply companies: AGR Co., Brunswick, Ohio; Carboline Co., St. Louis; Carlisle Tire and Rubber, Carlisle, Pa.; Celotex Corp., Tampa, Fla; Central States Assoc., West Des Moines, Iowa; Firestone Industrial Products, Noblesville, Ind.; GAF Corp., New York; Gates Engineering Co., Wilmington, Del.; General Tire and Rubber Co., Toledo, Ohio; Goodyear Tire and Rubber Co., Akron, Ohio; Kelly Energy Systems Fabricators Inc., Waterbury, Conn.; Johns-Manville, Denver; PIB Roofing Products, Swampscott, Mass.; Plymouth Rubber Co., Canton, Mass.; Republic Powdered Metals, Medina, Ohio; JP Stevens & Co., Easthampton, Mass.; Syenergy Methods Inc., Cranston, R.I.; Tremco, Cleveland; Vulcan Technologies Inc., San Antonio; and WeatherGard Building Products Co., Memphis, Tenn.
1983- In the March/April issue, a Duntile Manufacturing System is advertised for $48,760. Tile Manufacturers listed in the issue include Celotex-Marley Inc., San Bernardino, Calif.; Gory Associated Industries Inc., North Miami, Fla.; International Tile & Supply Corp., Los Angeles; Ludowici-Celadon, New Lexington, Ohio; Monier, Orange, Calif.; and Staco, Phoenix. In other news, Foamular 250 extruded polystyrene insulation gets UL approval for use in ballasted single-ply roofs using a gypsum recovery board, and the Single Ply Roofing Institute held its first annual meeting in Miami.
1984- ABC Supply, begun in 1982, had 25 stores and was named by Inc. magazine as the third fastest growing company in the United States.
1988- In January, Supradur Companies Inc. purchases and modernizes the Atlas Turner asbestos manufacturing plant in Montreal. The $12.5 million conversion costs are the first step in developing non-asbestos fiber cement products. Meanwhile, Kelly Energy Systems publishes a 13-page paper on the KES equalizer valves. Uplift pressure on the roof is released through the valves, which are said to secure EPDM or thermoplastic membranes against winds over 100 mph.
1988- In February, Wayne Mullis, founder and chairman of Universal Roofers, purchased roofing companies in Dallas and Las Vegas. With 800 employees, offices in four states and $60 million in revenue, the company is seen as a model for growth of the super contractor, sharing employees, equipment and expertise.
1989- In an article in the May issue by the Metal Building Manufacturers Association, Thomas H. Porterfield, an insurance executive in Washington, D.C., reported that roofing is the single most identifiable claim against architects and engineers. The issue also included a report on how sheet metal and roofing contractors vie for the same work. The year before, the California Licensing Board introduced a new classification: metal roofing contractor.
1992- On August 24, Hurricane Andrew strikes the Miami area, becoming the most expensive natural disaster in U.S. history. Building codes and their enforcement are strengthened statewide.
1994- The September issue reported that over 2.3 billion square feet of metal was installed in 1993. According to a survey by the Metal Construction Association, this marked a 16 percent increase over the previous year. In an article by the newly formed Metal Roofing Systems Association, there is no mention of the cool roof benefits of metal roofs.
1995- The World Trade Center Complex is featured on the cover of the June issue, highlighting a reroofing project on World Trade Center 7.
