Run the numbers before anyone runs them for you.
This calculator shows monthly payment, total cost, and total interest — including the part most financing pages leave out. Move the sliders and decide for yourself whether financing makes sense.
What a project actually costs per month.
Real amortization math — M = P·r / (1 − (1+r)−n) — not a marketing table. Adjust the amount and the rate to match a real offer.
- The 12-month row assumes a 0% deferred-interest promotion paid in full before the window closes
- The 60- and 120-month rows use the APR you set, amortized conventionally
- Total cost and total interest are shown for the 120-month term, because that is where the trade-off is largest
- Nothing here is a credit offer or an approval — rates and terms come from the lender
Offset worth claiming
A UL 2218 Class 4 roof commonly earns a 10–25% credit on the wind-and-hail portion of your premium in Texas. We hand you the certificate and itemized invoice your agent needs.
Illustration only. Not a credit offer, application, approval, or guarantee of terms. Actual APR, term, fees, and eligibility are set by the lender based on your credit. The 9.99% default is a placeholder rate for demonstration and must be replaced with A1’s actual lender program terms before launch.
Should I finance a roof replacement or wait and save?
Wait if the roof is intact and you can save inside a year or two — interest is a real cost and the calculator above shows how large it gets over a 120-month term. Finance if the roof is actively failing, because water entering the assembly compounds into decking, insulation, drywall, and mold work that costs multiples of the roof itself, and an unrepaired roof can trigger a maintenance-neglect denial on a later claim. The decision is about whether the damage is progressing, not about the monthly payment.
Four structures, and what each one is actually good for.
Lender programs change, so these are described as structures rather than as named offers. Ask any lender which of these shapes their product is, then read the reset or deadline terms.
Deferred interest promotion
No interest if the full balance is paid within the promotional window. Useful when you are waiting on an insurance payment, a bonus, or a property sale. The catch is real: if any balance remains at the deadline, interest usually accrues retroactively from day one.
You have a known lump sum coming inside the window.
Fixed-rate installment
A conventional amortizing loan at a fixed rate with a fixed monthly payment. No surprises and no retroactive interest. The longest terms produce the smallest payment and by far the largest total interest — which is exactly what the calculator is here to show you.
You want a predictable payment and no deadline risk.
Reduced payment / low APR
A lower promotional APR for a defined period, then a standard rate afterward. Read the reset rate, not just the teaser. This is the product where the difference between the advertised payment and the eventual payment is largest.
You expect to refinance or pay down before the reset.
Home equity / HELOC
Usually the lowest rate available because it is secured by your house — which is the trade-off. Closing costs and a slower approval process apply, and a default risks the home. We do not originate these; your bank or credit union does, and for a large project it is worth a phone call.
The project is large and you are not in an emergency.
A1 Hill Country is not a lender and does not make credit decisions. Financing is provided by third-party consumer lenders under their own terms. Specific lender names, program numbers, and disclosure documents must be added here before launch.
Three things that cost people money.
Deferred interest is not 0% APR
On a deferred-interest product, interest accrues from day one and is added retroactively if any balance remains when the promotion ends. A true 0% APR promotion does not do that. The words are similar; the outcomes are not.
Nobody may pay your deductible
Financing your own share of an insured loss is legal and normal. A contractor waiving, absorbing, or rebating your deductible is prohibited under the Texas Insurance Code and exposes you as a participant in fraud.
Compare APR and total cost, not the payment
Stretching a term always shrinks the monthly number and always grows the total. The calculator shows both on purpose — a payment quoted without a term and an APR is not information.

Financing math only means something against an actual itemized scope. Start with the number, then decide how to pay for it.
Answered without the pitch.
Do you offer roof financing with no money down?
Lender programs commonly available for roofing and remodeling include zero-down structures, deferred-interest promotional periods, and fixed-rate installment loans. Which of those you qualify for and at what rate is the lender's decision based on your credit profile — not ours. We show you the payment math before you apply so you can decide whether financing makes sense at all.
Can I finance my insurance deductible?
You can finance the portion of the work you are responsible for, including a deductible, through a legitimate consumer lender. What no contractor may do in Texas is waive, absorb, or rebate your deductible — that is insurance fraud and it exposes you as a participant. Financing your share is legal; having a contractor pay it is not.
Does financing cost more than paying cash?
Yes, unless you are inside a genuine zero-interest promotional period and pay it off before that period ends. Interest is the price of not waiting. The calculator here shows total cost and total interest specifically so the trade-off is visible rather than buried in a monthly figure.
What happens if I do not pay off a deferred-interest promotion in time?
On most deferred-interest products, interest accrues from day one and is retroactively added to the balance if any amount remains at the end of the promotional window. That can be a large, sudden charge. Read whether your offer is "deferred interest" or "0% APR" — they behave very differently at the deadline.
Is a home equity loan better than contractor financing?
Often cheaper in rate terms, because it is secured by your house — which is also the risk. A HELOC or cash-out refinance typically carries a lower APR than unsecured contractor financing but puts your home on the line and involves closing costs and a longer process. For an emergency roof replacement, speed sometimes decides it. Compare the actual APR and total cost, not the monthly payment.
Will a Class 4 roof lower my insurance enough to help pay for it?
It helps and it rarely covers the whole payment. Texas carriers commonly credit 10–25% of the wind-and-hail portion of the premium for a UL 2218 Class 4 roof. On many Hill Country policies that is a few hundred dollars a year — meaningful against a financed payment, and worth claiming with the certificate we provide, but not a substitute for the math.
