How do you make a roof out of card?

To make a roof out of cardboard, start by cutting two rectangular pieces to serve as the base and the sloped sides. Fold the rectangles into triangles for the sloped sides, and secure them to the base using glue or tape. Optionally, you can add shingles by cutting smaller rectangular pieces and layering them on the sloped sides for a more realistic effect. Finally, ensure the structure is stable by reinforcing the joints with additional cardboard or tape.
