Roof Replacement
Roof replacement is the removal of an existing roof covering and installation of a new one. It is typically needed when a roof has reached the end of its useful life or sustained extensive damage.
Methods[edit]
- Tear-off — the old covering is fully removed down to the deck before new materials are installed
- Overlay (reroof) — a new layer is installed over the existing covering; local codes may limit the number of layers
Cost factors[edit]
The cost of a roof replacement depends on the size and slope of the roof, the chosen material, tear-off requirements, access, and the local market.
Signs a roof may need replacement[edit]
- Widespread curling, cracking, or missing shingles
- Granule loss and visible bare spots
- Recurring leaks despite repairs
- A roof that is 20–30 years old, depending on the material
