This episode was recorded during the roofing boom—when being busy hid bad numbers. Today, work is slower and margins are tighter. Dave explains why job costing is now the difference between surviving and disappearing, and why “gut feel” leaves contractors broke even even when they’re busy.

This interview was recorded a few years ago when the roofing market was on fire. Phones were ringing, jobs were everywhere, and being busy hid a lot of sins.

Today it’s different.

Jobs are harder to get. Margins are thinner. And the contractors who don’t truly understand their numbers—what jobs actually make money, what crews are profitable, what their real labor cost is—those companies won’t survive this market.

I hear it every week:

“Dave, we’re working like crazy… but there’s never any money in the bank.”

That’s not bad luck. That’s no job costing.

Successful contractors job cost every job. Unsuccessful ones run on gut feel—and in this market, gut feel will put you out of business.

In this conversation, Dave Sullivan sits down with construction finance expert Leslie Shiner to break down the simple job costing system profitable roofers use to protect margins and make real decisions.
