Bridge loan vs. working capital for a roofing business — which fits?

A bridge loan fits a one-time, time-boxed gap on a specific roofing project — front-loaded material and mobilization costs you'll repay in a lump sum when the first draw or permanent financing lands. Working capital fits ongoing, recurring needs — covering payroll, fuel, and shingle inventory across the normal lag between outgoing costs and incoming progress payments.

Put simply: use a bridge loan when you can name the single event that repays it (a draw, a property sale, an SBA approval). Use working capital when the need repeats every cycle and there's no single payoff event — you're smoothing seasonal dips, not bridging one deal.

The distinct use cases

Bridge financing is built around an exit. On a large commercial replacement, you might float tear-off labor and a truckload of membrane for the first 60–90 days, then retire the balance when progress billing clears. If you can't point to the event that pays it back, a bridge loan is the wrong tool.

Working capital has no single exit — it's revolving, operational money. The SBA's 7(a) program explicitly lists "short- and long-term working capital" among its core uses, the same way it funds equipment or real estate. Working capital loans "cover day-to-day operating expenses—things like payroll, inventory, rent, and marketing—when your cash flow has a temporary gap," repaid through recurring weekly, monthly, or revenue-based payments rather than one balloon. For the recurring-payroll-between-draws pattern, that fits our roofing contractor working capital product.

Cost and term differences

Term. Bridge loans are short and event-driven — typically 30 days to 12 months, with 12 months the most common choice. Working capital runs a bit longer and steadier; Mercury notes a "short period (typically 6–24 months)", and the SBA's Working Capital Pilot caps maturity at 60 months.

Repayment shape. A bridge loan is usually an "interest-only loan with a balloon payment" — small monthly interest, full principal due in a lump sum at maturity. Working capital amortizes: the SBA 7(a) is repaid through "monthly payments of principal and interest from the cash flow of the business". That structure matters for a roofer — a balloon assumes the draw arrives on time; if a weather delay pushes the draw, the lump sum still comes due.

Cost. Bridge speed is expensive. Working-capital bridge rates run roughly 8–24%+ APR, plus an origination fee of 1% to 3% of the loan at closing. SBA-backed working capital is cheaper but slower; the 7(a) Working Capital Pilot caps the lender margin at base rate + 3.0% to + 6.5% depending on size. Bridge funding can hit your account in 24 to 72 hours; SBA approval takes weeks.

Which fits your roofing business?

Choose a bridge loan for one named, front-loaded commercial job with a clear repayment event — see our short-term bridge loans and the 2026 roofer's guide to construction bridge loans. Choose working capital for the recurring payroll-and-inventory gap that returns every season. Many roofers run both: bridge the big job, keep a working-capital line for everything else.
