Understanding Tear-Offs

Tear-Off: A tear-off is the removal of existing roofing materials before installing a new roof system.

Published: June 4, 2026 Reviewed: June 4, 2026 Updated: June 4, 2026 By Exterior Echelon

A tear-off is the process of removing old shingles, underlayment, flashing, and related roof materials before installing the new roof.

Why It Matters

Tear-off exposes the roof deck so damaged decking, hidden leaks, and old installation problems can be corrected before the new roof is installed.

Common Problems

Common concerns include poor property protection, missed deck damage, debris in landscaping, and rushing installation before the roof surface is properly prepared.

Building Codes & Industry Standards

Many situations require removal of existing roof coverings before a new roof can be installed. Local code and manufacturer requirements should be followed.

Exterior Echelon Notes

Exterior Echelon treats tear-off as an important quality-control step because the new roof is only as good as the surface and details underneath it.
