Generally, raw materials employed in the manufacture of roofing underlying materials are asphalt, cellulose base (organic), fiberglass substrate, and polymers (including polyethylene and polypropylene). Based on product type, the roofing underlying materials market has been segmented into asphalt-saturated felt, rubberized asphalt, and non-bitumen synthetic. Asphalt-saturated felt and rubberized asphalt are asphalt based; however, rubberized asphalt derives its elastic properties from rubber-like materials (mostly polymers) added during the manufacturing process. Roofing underlying materials are commonly used in applications such as residential construction, non-residential construction, and commercial constructions such as buildings, hotels, offices, public outlets, and educational institutes.
Non-bitumen synthetic roofing underlying materials segment was the largest product segment of the roofing underlying materials market, constituting more than 35% share in terms of volume in 2015. Synthetic underlying materials are preferred over asphalt-based underlying materials, as the synthetic materials are easier to install and can withstand harsh environments better than the asphalt-based materials. Synthetic underlying materials also provide better resistance to moisture, rain, vapor, UV radiation, and fungal damage. This segment is also estimated to be the fastest growing product segment of the roofing underlying materials market during the forecast period.
Non-residential segment was the largest application segment of the roofing underlying materials market, accounting for more than 40% share in terms of volume in 2015. Residential construction is anticipated to be the fastest expanding application segment, growing at a CAGR of 4.6% from 2016 to 2024. Growth in the construction industry and increase in construction activities (such as amusement parks, hospitals, and institutions) due to rapid urbanization are projected to drive the demand for roofing underlying materials in the near future.
