How to Find Roof Rafters

Locate the ceiling joists. These are the horizontal boards that support the ceiling drywall or plaster. They are typically made of 2x8 or 2x10 lumber.

Look for the ends of the ceiling joists where they meet the exterior wall. There will be a gap between the end of the joists and the wall.

Shine a flashlight into the gap to look for the roof rafters. The rafters will be running parallel to the ceiling joists.

The rafters may be covered with insulation, so you may need to move some of the insulation aside to get a clear view.

Once you have located the rafters, you can measure them to determine their size. The rafters are typically made of 2x6 or 2x8 lumber.

The rafters are spaced at regular intervals, typically 16 or 24 inches apart.

By following these steps, you can easily find the roof rafters in your home.
