Kirsch Building Products is focused on developing and marketing premium products that provide value and long-term solutions for the roofing industry. The company’s marketing efforts are focused on the pitched roofing market, which consists primarily of concrete/clay, slate, metal and asphalt composition shingles. Today, Kirsch Building Product’s industry proven Sharkskin family of roof underlayments are distributed Nationwide. What Tyvek* is to housewrap, Sharkskin is to roof underlayment.

The company can track its beginning with the development of products by its founder Mark C. Strait. The company was born out of the long-term experience and product research and development of Mark, who has studied the pitched roofing industry both in the USA and abroad. As a roofing contractor for over 26 years, Mark has witnessed, on a practical level, the failures of the current form of roofing felts, especially under tile roofing. Kirsch Building Products LLC focuses on providing premium roof underlayments and other roof accessories that provide features and benefits that promote the long-term success of the entire roof system.
