Four Decades of Earned Trust
Founded in 1978 and headquartered in Frankfort, Illinois, Hamstra Roofing is a second-generation, family-owned company built on the belief that honest work, deep craft knowledge, and genuine care for the customer are the foundation of a lasting business.
Every estimator is a trained roofer first. No commissions. No pressure. Just honest assessments of what your roof actually needs.
In-house sheet metal fabrication, bulk shingle warehousing, and a dedicated service department — full quality control from material to installation.
Hamstra regularly donates labor and expertise to local ministries and charitable organizations, treating stewardship as a core business responsibility.
"Making roofs last longer is the most green thing you can do." Hamstra invests in materials and techniques that extend roof life rather than accelerate replacement cycles.
Founded in Frankfort, IL
The first generation of Hamstra leadership establishes a roofing company on the principle that physical mastery of the trade is non-negotiable for anyone in leadership.
