Why Strong Contractors

SPFA Accreditation is the most rigorous quality standard in spray foam roofing. It demands proven installation quality, trained personnel, in-house equipment, and documented performance — across every project, every time. No other contractor in Colorado holds this credential.

Every scope is executed by our own trained, in-house crews. No handoffs. No subcontractors. This means one point of accountability, tighter quality control, and a team that shows up on your schedule — and owns the outcome.

An EMR of 0.94 — consistently below industry average — reflects a safety culture built into every phase of every project. Independent third- party audits, monthly on-site inspections, and a Job Hazard Analysis on every scope. No shortcuts.

From the roof deck to below grade, Strong Contractors performs work that most contractors can't — SPF, coatings, below-grade waterproofing, air and vapor barriers, industrial coatings, traffic coatings, ballast removal, and geotechnical foam. Complex facilities need a contractor who can handle the whole envelope.

Strong Contractors is vertically integrated — owning every phase of execution from estimation and procurement to field installation and closeout. No handoffs to third parties. No fragmented accountability. Our in-house crews, in-house equipment, and integrated specialty scopes mean tighter quality control, faster response times, and a single point of responsibility across roofing, coatings, waterproofing, and building envelope services.
