Drone shots turn into a roofing proposal.
Upload the drone capture set, send it through Left Horizon's roofing AI, and get back the roof condition, model outputs, and estimate foundation the contractor needs.
Drone upload
Contractors upload site drone shots to the server so the job can start without manual measuring or waiting on a full inspection workflow.
AI proposal build
The run detects roof condition, builds the model outputs, and prepares an immediate estimate proposal with pricing for the customer.
One place for the customer, quote, contract, work, and payment.
Left Horizon is becoming the operating record around the estimate: who the customer is, what property was scanned, what was quoted, what was sent, what was signed, and how the job closed out.

Versioned review
Current data stays live while generated assets remain immutable.
A private operating system for roofing estimates.
Left Horizon combines drone-based roof intelligence with the client management layer contractors need after the scan: quotes, customer review, contracts, work proof, payment records, and searchable customer history in one guided workspace.
