This 48-Page booklet examines each of the three main categories of underlayment products, including traditional, specialty and synthetic. The first part describes the market forces influencing the development of underlayment products. The second part provides a photo essay of the manufacturing process for each product category. The final part builds on the understanding developed in the first two parts, comparing the benefits of specific products for various roofing applications. A digital version (PDF) of the publication is available free-of-charge from Tarco, a leading manufacturer and supplier of roofing materials for the residential and commercial roofing marketplace.
