Roof restoration cost vs. full replacement: a real breakdown

A full roof replacement for an average single-family home typically involves a complete tear-off, disposal of old materials, and installation of new shingles, underlayment, and flashing — a multi-day project with a correspondingly higher price tag.

Roof restoration treats the existing shingles in place. There's no tear-off, no dumpster of waste, and most residential jobs complete in one to two days rather than a week or more.

The tradeoff: restoration only works within a specific window. Once granule loss exceeds roughly 30%, or a roof has recurring leaks pointing to poor original installation, replacement becomes the safer long-term choice. This is exactly what a free inspection is designed to determine before any money changes hands.
