About Kirsch Building Products...
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.

Sharkskin underlayment – designed for roofers by a roofer.
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.
