Interlock does not lend money, make credit decisions, or set financing terms. Financing is offered by independent third-party lenders and is subject to credit approval. This page is general information, not an offer of credit.

01

Re-roof now, save for a lifetime

One financed lifetime roof replaces the 15–20-year asphalt cycle — no more tear-offs, dumpsters, or five-figure surprises. Two asphalt roofs cost more than one Interlock roof; you'll buy one or the other.

02

Affordable and flexible

Monthly, bi-weekly, or weekly schedules on approved credit — matched to how your household actually budgets. Seasonal promotions periodically add 0% financing for the first year (O.A.C., 10% down).

03

The roof pays some of it back

The Alunar® finish is CRRC-rated and reflects solar heat instead of holding it, the lifetime transferable warranty adds resale value, and the replacement cycle you're not paying for is the biggest saving of all.
