AJ Construction is a Johns Manville certified contractor — a manufacturer designation for installers who meet JM's installation standards and are authorised to issue factory-backed membrane warranties.
Elevate (formerly Firestone Building Products) certification qualifies AJ Construction to install Elevate single-ply roofing systems and issue manufacturer-backed warranties across our nine-state region.
We work with facilities directors and purchasing departments across Missouri and the nine-state region. Submit your building below — we’ll review it and respond within one business day.
01
Every K–12 installation is planned around the academic schedule. Work begins after the last bell and must be watertight before the first day back. No exceptions, no renegotiations.
02
We participate in public bid and formal tender processes. If your district has already posted the job, send us the IFB number or portal link — we’ll pull the documents and submit a compliant proposal.
03
Every installation carries a documented 15-year membrane warranty — transferable, insured, and manufacturer-backed. It outlasts the budget cycle and survives the next three superintendents.
Every submission is reviewed by our estimating team. Required fields are marked *
