CAPITAL EFFICIENCY FOR ROOFING COMPANIES

Working capital is the silent constraint above export const SCALE_POSTS: Post[] = 0M revenue. The four levers that free up cash without hurting growth.

BY Jonathan Bloom·Finance

Roofing is a working-capital business. Materials get ordered and paid for before the homeowner pays. Crews get paid weekly while invoices age 30–60 days. Insurance claims sit in process for 45–90 days. The bigger the company, the more cash is tied up in the middle.

Most $10M+ roofers carry working capital equal to 8–14% of revenue. That's $800K–$1.4M sitting in receivables, work-in-progress, and prepaid materials. Freeing up a chunk of that is the single highest-leverage move an 8-figure operator can make on their balance sheet.

Lever 1: AR cycle time

The biggest lever. Most roofers run AR days outstanding (DSO) at 38–55 days. Operators with disciplined AR automation routinely get to 22–32 days.

Mechanics:

First invoice sent the day of completion, not three days later when the bookkeeper gets to it.

First reminder at day 5 (residential) or per the contract milestone schedule (commercial).

Partial payment option offered at day 10.

Lien-warning letter at day 25.

Lien filing at day 35 if applicable.

Median AR recovery from running this cadence consistently: 5–8% of receivables that were quietly bad. On a $10M operator, that's $40K–$80K of cash that wasn't going to come in.

Lever 2: Supplier terms

At $10M+ revenue you have leverage with suppliers. Most operators haven't renegotiated terms in years. Standard terms are net-30; net-45 or net-60 is achievable if you push.

What 15 extra days of supplier terms gets you: roughly 4% of annual material spend in free working capital. On a roofer doing $4M in material annually, that's $160K less cash tied up.

The conversation is straightforward. "We're doing $X with you and growing. We need net-45 terms." Most suppliers will agree. The ones who won't are probably mispriced anyway.

Frequently Asked Questions

Can I do all four levers at once?

Yes, and you should. They reinforce each other — clean WIP makes AR discipline easier, AR discipline gives you more cash to negotiate supplier terms from a position of strength.

What's a realistic AR DSO target for a roofer?

22–32 days on residential retail. 30–45 days on insurance restoration (carrier timing is partly out of your control). 35–55 days on commercial.

What happens if a supplier won't budge on terms?

Find a second supplier. Most categories have multiple options; if your current supplier won't negotiate, the leverage is yours to use elsewhere.

Do I really need to file liens?

Yes, on commercial and on large residential balances. The threat of the lien is what gets paid; the actual filing is rare. A consistent process makes the threat credible.

What if I'm growing fast enough that working capital is always tight?

Then squeeze the levers harder and finance the remainder. Growth that outruns working capital is a real risk; growth that's financed responsibly is fine.
