During the process of manufacturing asphalt shingles in Roofing Product Assembly, a heated tar-like material or hot melt butyl is applied to the underside of shingles as a sealing strip. Once installed on a roof, the sun warms this sealing strip and the top shingle is adhered to the one below it, thus preventing wind gusts from causing the shingles to flap. Valco Melton provides specific adhesive dispensing systems for these manufacturing needs. Whether it is shingles, metal roofing products, or other roofing materials, we can provide high-quality service to meet your customized needs. To learn more, contact us today.
