Crowther Roofing & Sheet Metal, Inc.

What Crowther Roofing & Sheet Metal, Inc. does

Crowther Roofing & Sheet Metal, Inc. is a third-generation, family-owned commercial construction services company headquartered in Romeoville, Illinois, founded in 1955 by Thomas H. Crowther. The company delivers an integrated building-envelope solution to commercial, industrial, and institutional property owners and facility managers across the Midwest, with documented project work in Illinois, Wisconsin, Ohio, Indiana, Mississippi, South Dakota, and Florida. Its core offerings span three integrated trades: commercial roofing (EPDM, TPO, PVC single-ply; APP and SBS modified bitumen; built-up; tile, shingle, and green roof systems); architectural sheet metal (in-house fabricated standing seam metal roofing, wall panels, gutters, downspouts, parapet caps, fascia/soffit, and custom column covers); and commercial HVAC (ductwork, rooftop units, exhaust fans, split systems, kitchen ventilation, design-build, and new construction). Adjacent service lines include aluminum composite panel cladding (Reynobond, Alucobond, Pac-Clad), roof coatings, solar mounting support, metal roof retrofit/overlay systems, and custom canopy systems.

The company earns revenue through project-based professional services contracts — installation, repair, maintenance, retrofit, and design-build work — delivered via a direct field-sales motion targeting enterprise property owners, facility managers, and general contractors. Pricing is quote-based and project-specific, with manufacturer-backed warranties available on nearly all roof systems installed. GTM is supported by authorized-installer partnerships with six leading commercial roofing manufacturers (Elevate, Johns Manville, Carlisle, Garland, Soprema, Tremco) and by a website, YouTube channel, and newsletter presence emphasizing project portfolio and craftsmanship.

Crowther employs 101-250 people and is led by CEO Scott Crowther Sr. and President Scott Crowther Jr., with a broader management team covering HVAC, sheet metal, and roofing superintendents, a controller, and business development/estimating capacity. Competitive positioning rests on 70+ years of family-owned continuity, 200+ years of combined team experience, a sub-1.0 EMR safety rating that unlocks high-risk job sites, in-house sheet metal fabrication, and a single-source multi-trade offering that is uncommon for a regional contractor of its size.
