The RH Score is a statistical estimate of roof condition derived from address, climate-exposure, and roof-characteristic data. It is not a warranty, a guarantee, or a substitute for a physical inspection by a qualified professional. Figures shown across this site are illustrative and do not represent a score for any specific property.
Where the methodology references published standards — such as UL 2218 for impact or ASTM D7158 for wind — it does so to describe the engineering basis of its peril modeling. Alignment with a standard is not certification, endorsement, or accreditation by UL, ASTM, or any standards body. No such affiliation is implied.
The RHS Center was incubated by a Québec-based nanotechnology company developing roof treatment products. The Center is independently governed and applies its methodology to all qualifying products on equal terms. No affiliated product receives a scoring advantage. We disclose this relationship up front rather than waiting to be asked.
The RH Score is built to evolve on numbered methodology versions. The version that produced a score is intended to travel with it, so a number can be traced back to the rules that generated it, and changes between versions can be attributed to the roof or to the methodology rather than left ambiguous.
This site describes a standard that is actively under development. Statements about governance, integrations, dispute rights, and availability describe design commitments and intentions, not features that are necessarily live today. We have tried to mark what is built versus what is planned, and to avoid presenting either as the other.
Nothing on this site constitutes insurance, engineering, financial, or legal advice. The RH Score is one input among many and is not intended to be the sole basis for any decision that carries real-world consequences.
