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.

Zero Energy Buildings: When Do They Pay Off in a Hot and Humid Climate?

There’s lots of talk about zero energy as the next big milestone in green building. Realistically, how close are we to this ambitious goal? At this point, the strategies required to get to zero energy are relatively expensive. Only a few buildings, most of them 6,000 sf or less, mostly located in California and similar moderate climates, have hit the mark. What about larger buildings, commercial buildings, more problematic climates? Given the constraints of current technology and the comfort demands of building users, is zero energy a worthwhile investment for buildings in, for example, a warm, humid climate?
