Step-by-Step Guide to Tie a Gable Roof
1. Measure and Plan
- Measure the side wall height and roof pitch.
- Mark the intended roof line with a chalk line.

- Cut rafters to match the roof pitch.
- Install them at intervals specified by local building codes (usually 16–24 inches).
- Secure rafters to the ledger board using metal brackets or hurricane straps.
4. Add Ridge Beam and Collar Ties
- Position the ridge beam at the peak of the gable.
- Connect rafters with collar ties to prevent spreading and sagging.
- Double-check all connections for level and stability.
5. Sheathing and Roof Covering

- Test stability by gently applying pressure at critical joints.
- Make adjustments where necessary to prevent gaps or misalignment.
Safety Tips
- Always wear a safety harness when working on a roof.
- Use scaffolding for high walls to avoid ladder accidents.
