Key findings of the roofing survey

  • Respondents named metal (56%) and EPDM (50%) as the roofing systems they (or their firms) employed most in projects. However, the results show that they used a wide variety of roofing types, including built-up, shakes and shingles, modified bitumen, TPO, PVC, and tiles.
  • Insulation choice was also spread among several product categories, with polyisocyanurate leading the way (62%) and EPS, XPS, and sprayed polyurethane foam also showing support.
  • More than half of respondents (53%) said their roofing projects were essentially all low-slope jobs (2/12 rise or less), but nearly a third (31%) said steep-slope roofs (>2/12 rise) comprised all or almost all of their roofing-related projects.
  • New construction and retrofits were fairly evenly split among respondents’ roofing-related projects over the last couple of years.
  • Initial cost is not the most important factor in choosing a roofing system. That honor went to durability and reliability, at least from the experience of respondents and their perception of their clients’ priorities.
  • In a related finding, it is not surprising that “leaks or failures” (42%) was the single biggest concern or worry expressed by respondents, along with such related factors as “quality/performance” (17%) and “incorrect installation” (11%). Again, cost was not the key concern, with only 13% of respondents checking it as their number one worry.
  • In terms of “green” factors, energy efficiency (52%) is far and away the crucial component of a roofing system, followed distantly by life cycle cost (25%).
  • Building information modeling is still largely in its infancy in respondents’ roofing-related projects, with less than one-third (32%) saying that they used BIM. However, the use of BIM is expected to grow to about 59% over the next two years or so.
  • Only a small percentage of respondents (4%) said they (or their firms) have made extensive use of photovoltaics on roofs in the last two years, but three in 10 (30%) had used PVs in a few projects. The upside is that 57% plan to do so in the next 18-24 months.
  • Similarly, the extensive use of green vegetative roofs is limited (2%), but 23% of respondents (or their firms) have tried them in at least a few projects in the last two years, and 38% said they intend to do so in the next 18-24 months.

Survey Methodology

The survey was emailed to a representative sample of BD+C’s subscriber list. No incentive was offered; 263 qualified returns were obtained. The majority of responses (52%) came from architects and designers, a group that represents half of BD+C’s subscriber base; however, respondents were spread across the professions and included nearly one-fifth (18%) from among owners and facilities directors. In terms of location, respondents’ roofing-related projects covered the entire U.S. (and a bit in Canada), although the Mid-Atlantic region may have been underrepresented (8%). A margin of error of 6-7% at the 95% confidence level can be applied in most cases.

Note: Some of the tables refer to “Top % rank,” the percentage of respondents who rated the factor as their single most important factor. “Weighted score” was calculated by tripling the number of respondents who rated the factor #1, doubling those who rated the factor #2 by 2, multiplying by one those who rated the factor #3 by 1, and dividing the sum by three to obtain the average.

Landscape architecture challenges Andrés Duany’s Congress for New Urbanism

Andrés Duany, founder of the Congress for the New Urbanism, adopted the ideas, vision,  and values of the early 20th Century landscape architects/planners John Nolen and Frederick Law Olmsted, Jr., to launch a movement that led to more than 300 new towns, regional plans, and community revitalization project commissions for his firm. However, now that there’s a societal buyer’s remorse about New Urbanism, Duany is coming up against a movement that sees landscape architecture—not architecture—as the design medium more capable of organizing the city and enhancing the urban experience.

Just for fun: Words that architects use

If you regularly use such words as juxtaposition, folly, truncated, and articulation, you may be an architect. Architects tend to use words rarely uttered during normal conversations. In fact, 62% of all the words that come out of an architects mouth could be replaced by a simpler and more widely known word, according to this “report.” Review this list of designer words, and once you manage to work them into daily conversation, you’re on your way to becoming a bonafide architect.
