Since 1961, the name Alan Kunsman continues to be synonymous with honesty, quality and customer satisfaction at a fair price. It is this attitude that has made us the recognized leader in roofing, siding, masonry and sheet metal in the Lehigh Valley. Still a family owned and operated roofing company, the pride and commitment which formed the foundation of our business, remains the same as when we began with only 2 employees and a pick-up truck. ​We are proud to offer manufacturer trained and certified installers in all areas of commercial and residential flat roofing, steep roofing, siding, waterproofing, windows, masonry and sheet metal applications. Whatever your needs may be, from a small slate roof repair to a new roof on an entire warehouse, we have the expertise and resources to get the job done right. We also offer a comprehensive inventory of steep roofing, flat roof materials, and siding supplies, beyond what is typically available elsewhere, at competitive prices.
