About Us

The Keystone Group, LLC was founded on the belief that success comes from
hard work and a commitment to excellence. Further, we believe that our firm’s
primary function is to act as the critical link (or keystone) between local clients
with roof problems/challenges and manufacturers that offer proven, quality roofing
solutions. We genuinely appreciate our contractor, distributor, design and Owner
customers and work everyday to earn their continued support by servicing them in
a competent and professional manner. Our goal is to bring value to their business
and always exceed their expectations. We view the firms we represent as true
partners and ask them to do the same. As partners, we share a commitment to
give each other our best effort. Our focus is to create and cultivate a long-term,
successful relationship that also benefits and supports our shared customers. The
Keystone Group is working everyday to become one of the Great Lakes region and
Canada’s premier roofing and waterproofing independent rep firms.
