What Is Roof Tear-Off?
Tear-off strips shingles, underlayment, and old flashings down to bare wood. It is the only moment in a roof's life when the decking is fully visible, which makes it as much an inspection as a demolition: soft OSB, cracked planks, hidden leak trails, and improvised past repairs all surface here, and this is why reputable contracts state a per-sheet decking price in advance rather than negotiating over an open roof. Tear-off also resets the roof's layer count to zero — enabling ice-and-water membrane, new drip edge, and modern underlayment that an overlay cannot add — and lets every flashing be replaced rather than reused. The process itself has failure modes: a house left open when a storm arrives (crews should tear off only what they can dry-in the same day), nails left in landscaping (magnet sweeps are standard), and vibration knocking attic dust loose. Homeowners should expect the deck photographed before covering; those photos are the evidence behind any decking charge.
Important Distinction
Note: Tear-off is when the roof's real condition is discovered — decking rot, bad flashing, missing drip edge — so change orders at this stage are often legitimate findings, and a bid's decking-replacement price-per-sheet should be agreed before this day, not during it.

How Roof Tear-Off Relates to Other Topics
Tear-off is the only inspection of the decking a roof ever gets - soft spots, delamination, and rot are found underfoot after the shingles come off, not from the driveway or the attic hatch.
Brittleness argues for tear-off timing too: shingles too fragile to repair are also too fragile to stay - a roof crews cannot walk without breaking it is announcing that its next storm is its last.
Related To Roof Tear-Off
An overlay nails new shingles over the old ones - cheaper up front, but it hides the decking from inspection, traps heat that ages the new shingles faster, and code caps a roof at two layers, so the next roof pays for both tear-offs.
A typical residential replacement is one to two days of noise, and tear-off morning is the point of no return - it is also the only moment anyone will ever see the decking, which is why mid-day supplement calls happen then.
