A contractor's estimate can look professional while still leaving important questions unanswered. You're asked to approve thousands of dollars of work based on a single page of line items.

This is a real report format on an anonymized roofing project — the findings, the side-by-side bid comparison, and the message homeowners send their contractor.
Interactive demo — anonymized roofing project
Three estimates: $18,400, $22,750 and $28,100. Click through what the review returned.
Tear-off materially changes both the cost and the manufacturer warranty. Without it in writing, the price is not comparable to the other two bids.
Ask: “Does this price include complete tear-off and disposal of the existing roof, and how many layers are you expecting to remove?”
An unpriced item discovered mid-job is negotiated at your weakest moment, with the roof already open.
Ask: “What is your installed price per sheet of replacement decking, and will you photograph any sheets you replace?”
Step and valley flashing are where most roof leaks begin. Reused, bent, or corroded flashing is a common source of callbacks.
Ask: “What would it add to replace all step, valley, and chimney flashing with new material?”
Your estimates and photos are stored privately and are never shared, sold, or published.
We never declare work defective or certify a contractor. We surface what to verify.
Payments are processed by Stripe. ProjectProof never sees or stores your card details.
No subscription, no upsells, no contractor kickbacks. We work for the homeowner only.
Three simple steps between your contractor's proposal and a clear, plain-English second opinion.
Step 1
Upload your contractor estimate, project photos, and basic project information.
Step 2
Our AI analyzes your proposal, project details, and photos to identify potential gaps, concerns, and questions worth asking.
Step 3
Receive a simple report showing potential concerns, questions to ask, and items worth verifying.
We can also summarize publicly available information about the contractor when available.
Every ProjectProof review returns the same six sections, written for homeowners.
01
What's included, missing, or unclear in the proposal.
02
Potential areas worth verifying, based on the photos you upload.
03
Questions written specifically for your project and proposal.
04
Items that deserve additional attention before you approve.
05
A professional message you can copy and send immediately.
06
What to verify before the project is considered complete.
You don't have to figure out how to raise a concern without sounding difficult. We generate a professional, specific message you can copy and send to your contractor.
Message to your contractor
“Thanks for the proposal. Before we approve the work, could you clarify whether replacement of damaged decking is included and, if not, what the unit price would be?”
What is included, excluded, unclear, or missing from the proposal?
Are important materials, products, specifications, or warranties clearly identified?
Do photos show anything that deserves closer attention?
Are payment terms, warranties, exclusions, change orders, cleanup, and other important terms clearly addressed?
What should you ask before approving the work?
What should you verify before considering the project complete?
Bonus: when you name your contractor, we can also summarize publicly available reviews, ratings, and licensing mentions we find. This is a supporting detail — the core of your report is the proposal itself.
Photos are never judged in isolation. Here's exactly what happens to each one you upload.
01
Add a photo of the work area, the materials, or the finished installation.
02
The report points to the specific detail in the photo that stands out.
03
Plain-English context on why that detail may be worth a second look.
04
A ready-to-send question so you can raise it with your contractor.
A photo alone can't prove work is defective, so we never claim it does. We point to what is worth verifying and give you the words to ask about it.
Upload up to three estimates in a single $19.99 comparison review. We normalize them line by line so you can see what each price actually buys. Illustrative example below.
| Line item | Contractor A$18,500 | Contractor B$21,200 | Contractor C$16,900 |
|---|---|---|---|
| Tear-off | Included | Included | Included |
| Underlayment | Included | Included | Not stated |
| Flashing | Not stated | Included | Not stated |
| Decking allowance | $X per sheet | $Y per sheet | Not stated |
| Cleanup & disposal | Included | Included | Not stated |
| Workmanship warranty | 10 yr | 15 yr | 5 yr |

Your Home Project Review
Why it matters
The proposal does not clearly identify the underlayment product or installation method.
Suggested question
“Can you confirm the underlayment product and installation method included in this proposal?”
What we saw
In your photo, the flashing at the chimney appears to be surface-sealed rather than woven into the shingle courses.
Why it matters
Chimney transitions are a common source of leaks, and the photo alone is not enough to determine whether the installation is defective.
Suggested action
“Can you confirm how the chimney flashing was installed and that it follows the manufacturer's installation instructions?”
A general chatbot will happily guess. Our review is built to do the opposite: it is constrained, cross-referenced, and required to say when it doesn't know.
The review reads the estimate you uploaded line by line — not a generic template of what roofing bids usually say.
Your quote is compared against published national cost ranges adjusted by a state construction cost index and your scope size.
Each trade is checked against a fixed checklist of the items a complete proposal should define — flashing, disposal, permits, allowances, warranty.
Named contractors are researched online for publicly available reputation and licensing signals, clearly labeled as unverified.
What the report will never do
It won't call work defective, illegal, or out of code — photos and a PDF can't establish that, and any tool claiming otherwise is guessing. It flags what's worth verifying and hands you the exact question to ask.
Every trade hides scope somewhere different. Pick yours to see what a complete estimate should spell out and what usually gets left out.
Straight answers on how the analysis works, what the AI will and won't say, and how your files are handled.
No. Upload your estimate and the free red-flag scan tells you how many potential scope gaps, ambiguous terms, and questions we found, plus the three biggest ones. You only pay if you want the full report with every finding explained, the side-by-side comparison, and the contractor message.
You upload your contractor's estimate (up to three), project photos, and basic details about the job. Our AI reads the documents and photos together, compares the scope against what a complete proposal typically includes for your project type, and produces a plain-English report: potential gaps, items worth verifying, questions to ask, and a ready-to-send message for your contractor.
The report highlights observations, potential scope gaps, and items worth verifying. It will never declare work defective, say a contractor is dishonest, certify quality, or replace a licensed inspection. Photos alone can't prove a problem, so every photo finding is framed as a question to raise — not a verdict.
Your files are stored in private, access-controlled storage and are only used to generate your report. They are never shared with contractors, sold, used for advertising, or made public. Only you can access your project, via your private link.
Uploaded estimates, inspection reports, and photos are kept for 90 days after your report is generated, then permanently deleted. Your written report stays at your private link for 12 months, after which the project record is deleted too. Unpaid or unsubmitted projects are removed after 30 days. You can request deletion at any time and we complete it within 7 days; backups roll off within 30 days.
No. We don't sell leads, take referral fees, or recommend specific contractors. When you name your contractor, we summarize publicly available reviews and licensing mentions — nothing more. The analysis is paid for by you and works only for you.
$12 one-time for a single contractor estimate, or $19.99 to have up to three estimates reviewed and compared side by side. Either way you get photo review, scope-gap analysis, personalized contractor questions, a final punch list, and a downloadable PDF report. No subscription.
Checkout is handled securely by Stripe. If a payment is refunded, expires, or disputed, your project page shows exactly what happened and when, with clear next steps and a support contact. Your report access is never silently removed.
