Built on trust, craftsmanship, and a handshake that holds.
We do not just build roof systems — we build long-term relationships with the people responsible for keeping St. Louis buildings running.
STL Commercial Roofing was founded on a simple idea: commercial building owners deserve a roofing partner who treats their property like their own. Over 25 years, we have grown from a small local crew into one of the metro's trusted commercial roofing teams — and we have kept the same hands-on approach the whole way.
We work exclusively on commercial and industrial buildings, so our crews live in the world of low-slope systems, coatings, and complex details every single day. That focus shows up in cleaner installs, fewer callbacks, and roofs that hit their full service life.
Whether it is a 2,000 sq. ft. storefront or a 400,000 sq. ft. distribution center, you get the same thing: a straight answer, a fair price, and work we are proud to put our name on.
What we stand on.
Craftsmanship
We install every system by the book — the manufacturer's and ours. The details you never see are the ones that keep you dry.
Integrity
Honest assessments, clear scopes, and fair pricing. If a repair will do, we will not sell you a replacement.
Safety
OSHA-trained crews and a sub-1.0 EMR keep our people safe and protect your property and your liability exposure.
Relationships
Most of our work comes from owners and managers who call us back. That trust is the whole business.
