When planning a roof replacement, homeowners often ask, should you remove all old tare paper when roofing house? The decision affects roof durability, installation ease, and overall protection. Understanding when and why to remove old underlayment ensures your new roof performs efficiently and avoids future problems like leaks or premature wear.

- Moisture Barrier: Prevents water from reaching the roof deck.
- Protection During Construction: Shields wood from rain and debris.
- Extra Insulation: Provides minor thermal and sound dampening benefits.
- Smooth Surface for Shingles: Ensures proper shingle alignment and adhesion.
