PerilProof is free to try on storms from more than five years ago. Everything else — the last five years, the roof estimate, saved work, your branding and daily storm alerts — needs one of these.
Roof measurement reports are sold to everyone — no account and no membership required.
There's no password — your access arrives as a link by email. Lost it? We'll send it again.

There's no account and no password with a one-time report — the link we emailed you is how you get back in on any device. Need it again? Open Get full access and use “Already bought a one-time report?”.
Every order is also delivered to the email you gave at checkout — this list is a convenience, not the only copy.
You can change this later in My Portal. Working in more than one state? National covers every state for $29.99/mo.
Two things can never be read from aerial imagery, and both change the number enormously — so PerilProof will not guess them.
Anything you attach is appended to the report as a labelled photo section.
The estimate is a preliminary budget figure from an automated roof measurement and regional unit costs — not a certified scope, an insurance adjustment, or an Xactimate® estimate. The report provides historical weather data only and does not assess damage or causation.
Create filters for the storms you care about — by state, or by a specific location and radius. Each morning, you get one email summarizing any qualifying hail, wind, or tornado reports from the previous day. Quiet days send nothing. Add as many filters as you like.

Add your company details and logo. They'll appear on every report as a "Prepared by" block, so your reports come out co-branded and professional. Saved in this browser.
PNG, JPG, or SVG. A wide/horizontal logo works best.
The estimate stays neutral by default. If this roof is tied to an insurance claim, add the details below and a claim-information block will appear on the estimate header. Leave blank to keep it neutral.
This is a free preliminary budget guide. Need professional roof measurements? Close this window and use the Order roof measurements button at the top of the results.
⚠ PLEASE MAKE SURE THE PROPERTY ADDRESS ABOVE IS CORRECT — THERE ARE NO REFUNDS ON WRONG ADDRESSES. Your files are prepared for that exact address.
One order per property. PerilProof stores nothing — your order travels by email from your own account. Every order is matched to its Stripe payment before work begins.
Bundles the historical weather summary, your roof estimate (if saved for this property), and any photos into one branded PDF for the carrier or adjuster. Provides historical weather data only — does not assess damage or causation.
Drop in an address list — or paste addresses below (one per line) — to scan them all at once: top storm date, largest hail, and strongest wind for each. Open any row for the full report. Up to 50 at a time.

By checking the box at sign-up or checkout, creating an account, buying a property pass, or otherwise using PerilProof, you agree to these Terms of Service and our Privacy Policy. If you're using PerilProof for a company, you agree for that company too, and "you" includes it. If you don't agree, don't use the service.
You agree not to: misuse or disrupt the service; attempt to access it in unauthorized ways; scrape, resell, or redistribute data in violation of our or our data providers' terms; use PerilProof to create or support a false, fraudulent, or misleading claim; or use it for any unlawful purpose, including making prohibited representations or offers in connection with insurance claims.
PerilProof, its software, design, and content are owned by PerilProof LLC and protected by law. We grant you a limited, non-exclusive, non-transferable right to use the service for its intended purpose. Reports and estimates you generate are for your own use, subject to these terms and our data providers' terms. Underlying public data remains subject to the terms of its sources.
PerilProof depends on third-party providers (including NOAA/NWS via the Iowa Environmental Mesonet, Google, Esri, OpenStreetMap/Nominatim, independent roof-measurement providers, Memberstack, Cloudflare, Resend, and Stripe). We do not control and are not responsible for third-party data or services, and their availability or accuracy may change. PerilProof is not affiliated with, endorsed by, or acting on behalf of NOAA or the National Weather Service.
THE SERVICE, ALL REPORTS, AND ALL DATA ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITH ALL FAULTS AND WITHOUT WARRANTIES OF ANY KIND, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE OR ANY DATA WILL BE ACCURATE, COMPLETE, TIMELY, UNINTERRUPTED, OR ERROR-FREE. THESE DISCLAIMERS ALSO APPLY TO ALL THIRD-PARTY DATA PROVIDED THROUGH THE SERVICE.
TO THE FULLEST EXTENT PERMITTED BY LAW, PERILPROOF LLC AND ITS OWNERS, MEMBERS, MANAGERS, EMPLOYEES, AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST CLAIM PROCEEDS, OR LITIGATION COSTS, ARISING OUT OF OR RELATED TO THE SERVICE OR ANY REPORT, UNDER ANY THEORY, EVEN IF ADVISED OF THEIR POSSIBILITY. OUR TOTAL LIABILITY FOR ALL CLAIMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM OR (B) $100.
You agree to defend, indemnify, and hold harmless PerilProof LLC and its owners, members, managers, employees, and agents from all claims, losses, liabilities, damages, costs, and expenses (including reasonable attorneys' fees) arising from (a) your use of the service; (b) any report you generated, shared, submitted, or relied on, including in any insurance claim or legal proceeding; (c) any legal process described in Section 17; or (d) your violation of these terms or applicable law.
We may suspend or terminate your access if you violate these terms or misuse the service. You may stop using the service and close your account at any time. Sections 3–10 and 12–19 survive termination.
We may update these terms. We'll post the new version with its effective date and, for material changes, ask you to accept again at your next sign-in or purchase. Continued use after that means you accept the update.
Governing law. These terms are governed by the laws of the State of Florida, without regard to conflict-of-laws rules, and, as to this Section 10, by the Federal Arbitration Act.
Try to resolve it first. Before starting an arbitration, the party with the dispute must send the other a written notice describing it and the relief wanted (to us at info@perilproof.com), and both parties will try in good faith to resolve it for 30 days.
Binding individual arbitration. Any dispute, claim, or controversy arising out of or relating to these terms, the service, any report, or any purchase, including the scope or enforceability of this agreement to arbitrate, will be resolved by final and binding arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules or, if you use PerilProof for a business, its Commercial Arbitration Rules. A single arbitrator will decide the dispute. The arbitration will take place in Hillsborough County, Florida, or, at your election, by video conference, telephone, or written submissions. Payment of arbitration fees is governed by the AAA's rules. Judgment on the award may be entered in any court with jurisdiction.
Exceptions. Either party may bring an individual claim in small-claims court if it qualifies, and either party may ask a court for an injunction to stop infringement or misuse of its intellectual property or of the service.
Class-action and jury waiver. You and PerilProof may bring claims against each other only in an individual capacity, and not as a plaintiff or class member in any class, collective, consolidated, or representative proceeding. The arbitrator may not consolidate claims of more than one person or preside over any class or representative proceeding. You and PerilProof each waive the right to a jury trial.
30-day opt-out. You may opt out of this agreement to arbitrate by emailing info@perilproof.com within 30 days after you first accept these terms, with your name, the email address on your account or purchase, and a clear statement that you opt out of arbitration. Opting out does not affect any other part of these terms.
If this section is limited. If the class-action waiver is found unenforceable as to any claim, that claim (and only that claim) will be decided in the state or federal courts located in Hillsborough County, Florida, and you and PerilProof consent to their jurisdiction. Any claim that is not subject to arbitration will also be decided in those courts.

PerilProof is software. It pulls publicly available historical weather records only from the sources cited in each result or report, organizes them, and displays them for areas near a U.S. property. It can also generate a preliminary roof-replacement budget estimate from an aerial measurement and regional cost averages.
PerilProof does not create, collect, observe, or independently verify any weather data. It only retrieves what the cited sources publish, and we are not responsible for the content of that source data.
You understand and agree that PerilProof:
PerilProof does not warrant that any weather event did or did not occur on any date, at any location, or at any intensity. A result showing a weather record does not mean that weather occurred at, or affected, a particular property. A result showing no record does not mean that weather did not occur.
All results and reports are generated automatically by software, without human review. They may contain mistakes, including errors, gaps, delays, or later revisions in the source data, and errors in how the software locates an address, measures distances, converts dates and times, filters, ranks, or summarizes events. Storm reports are preliminary and may be changed or removed by their sources, and radar-estimated hail size is a modeled value, not a measurement.
PerilProof makes no representation that its results are suitable to be relied on for any purpose, and any use of or reliance on PerilProof results is entirely at your own risk. If you are using PerilProof results in connection with an insurance claim, appraisal, mediation, arbitration, lawsuit, or other dispute, or relying on them in any other way, we suggest you retain a qualified weather expert, such as a forensic meteorologist, to independently review the weather at the property.
You alone decide whether to share a PerilProof report with anyone, including an insurer, adjuster, appraiser, umpire, mediator, court, or government agency, and you are solely responsible for that decision. If you share a report, you agree not to alter it or remove any date, source citation, report ID, or disclaimer, and not to describe it as an expert opinion, a certified or forensic weather report, or a determination of damage, causation, or date of loss, or as prepared by PerilProof for or on behalf of any party. Any report that doesn't match our records is not a PerilProof report.
PerilProof does not provide expert or fact testimony, depositions, or consulting in connection with any claim or dispute, and you agree not to identify PerilProof or its personnel as a witness or expert. We will respond to valid legal process (such as a subpoena or court order) only as required by law, and where permitted, we may respond through a written records-custodian certification instead of live testimony. If we receive legal process, a records request, or a demand for testimony relating to your account, your use of the service, or a report you generated or shared, you agree to reimburse our reasonable costs of responding, including staff time and attorneys' fees, to the extent the law allows. Unless the law prohibits it, we will try to notify you so you can seek protection if you want to.
No one, including you and any insurer, adjuster, appraiser, umpire, contractor, lender, or court, is entitled to rely on PerilProof results or reports, and no third party is a beneficiary of these terms. Our disclaimers and limitations apply to any claim relating to a result or report, whoever brings it.
Results are generated on demand from public data. We are not obligated to keep copies of reports, searches, or source data, and we may delete them under our normal retention practices. Keep your own copies of anything you may need later.
You must be at least 18 years old and provide accurate information. You're responsible for keeping your login credentials secure and for all activity under your account. Notify us promptly of any unauthorized use.
Billing. Memberships and one-time purchases (including property passes and roof estimates) are processed by Stripe. By purchasing, you authorize the applicable charges.
Subscriptions. Memberships renew automatically each billing period until canceled. You may cancel any time; cancellation stops future renewals, and you keep access through the end of the period you have already paid for.
One-time purchases. Property passes and estimate orders are charged per order at the price shown at checkout.
Refunds. Property passes are non-refundable once the pass is activated, reports are non-refundable once generated, and measurement or estimate orders are non-refundable once delivered. Orders placed for a wrong address are not refunded. Subscription fees are non-refundable. Canceling a membership stops future renewals. Nothing in this section limits any refund the law requires.
Price changes. We may change prices; changes apply to future billing periods and will be communicated in advance where required.
Taxes. You are responsible for any applicable taxes.
