Financial Hacks for Roofers: Cash Flow Over Loans

Welcome to Roofer Growth Hacks! In this episode, Chris Hunter sits down with Josh Luebker to talk about the financial side of growing a roofing company the right way. Josh shares how his background in large-scale construction project management led him into the world of fractional CFO services, where he now helps subcontractors and roofing companies solve cash flow problems, improve estimating, tighten up job costing, and make smarter growth decisions.

If you’ve ever wondered what a roofing company should fix first when cash flow gets tight, how much roofers should really spend on marketing, why job costing matters so much, when to lease versus buy trucks, or why new roofing companies should avoid taking on debt too early, this episode is for you.

Josh also shares his thoughts on AI, overhead, and what roofing companies need to pay attention to in 2026 and beyond.

About Josh:

Josh Luebker is the founder of The Construction CFO, where he helps subcontractors and roofing companies improve cash flow, job costing, estimating, billing, and overall financial clarity. Before starting the business, Josh spent years in project management on large-scale construction projects, including massive Google jobs, where he developed a deep love for planning, operations, and the math behind making projects work.

What makes Josh different is that he does not come from the traditional CPA or bookkeeping world. Instead, he brings an operations-first perspective to construction finance, focusing on what actually happens in the field and how that affects profitability. His work is centered on helping owners understand where money is being made, where it is leaking, and how to build systems that create long-term stability.

Today, Josh works with trade contractors across a range of sizes, helping them fix collections, improve estimating, benchmark overhead, build better financial systems, and make smarter decisions without relying on guesswork. He also offers free tools and templates for owners who want to get better control of their business finances.
