Rosemont, Illinois--The US National Roofing Contractors' Association has carried out an online survey of the roofing business in North America. The results show that EPDM dominates that low-slope and flat roofing business taking over 30 percent of the new roof business and 26 percent of the replacement roofing business in 2004. In the high slope sector, EPDM provides only about 3 percent of the materials consumed.
Low-slope work covers around 72 percent of the business, with steep-slope representing around 28 percent. Respondents said 25 percent of their low-slope work was new roofs, with 61 percent in re-roofing and the remaining 12 percent in repairs and maintenance.
The market share of EPDM materials declined from 33 percent in 2003. However, TPO materials provide about 12 percent of the new roofs, up from 11 percent in 2003. TPO materials cover about 9 percent of roofs in the replacement sector.
