These and other trends are presented in World Roofing, a new study from The Freedonia Group Inc., a Cleveland-based industrial market research firm. In contrast to developing regions, growth in demand for roofing in industrialized countries will be much more muted, with expansion projected at less than 2 percent annually through 2008. The maturity of the building infrastructure in many of these countries means that reroofing accounts for a higher share of demand. In the country with the largest single roofing market, the United States, a rebound in nonresidential construction activity from the doldrums of the early 2000s will aid demand for roofing, but it will be offset somewhat by a slowing in construction of single-family housing from an elevated pace that was boosted by low mortgage interest rates.

Bituminous roofing constituted the largest product segment in 2003, bolstered by the prominence of the material in the large North American market. Bituminous shingles dominate in U.S. and Canadian steep-slope applications, and these two countries account for more than three-quarters of worldwide demand for the product.

Tile roofing was the second largest product segment in 2003, with clay tiles and concrete tiles each with demand in excess of 600 million square meters. Growth will accelerate from that of the 1998-2003 period, fueled by increased building construction activity in developing countries in Asia, Eastern Europe and the Africa/Middle East region. Gains in Western Europe, the second largest regional market for tile roofing after the Asia/Pacific region, will be below the world average, but will reverse the trend from 1998 to 2003, when sluggish residential construction activity contributed to a slight decline in demand for tile roofing.
