How does a roof go on a house?
How a roof goes on a house. A true how-it-works story for kids 5–9.
The Domestic roof construction story, read aloud
Look at the houses along the street out your window. See the roofs on top? A roof is like a giant hat that keeps a house dry. But how does that hat get up there? First, builders stand up wooden triangles called trusses.
Lots of them get built in a factory, then ride to the house on a truck. A crane lifts them up, like a giraffe carrying sticks with its neck! Next, flat boards cover the triangles. Then come the shingles, and here is the clever part. Builders start at the very bottom edge and work their way up, row by row.
Each new row lies over the top of the row below it, like scales on a fish. So when rain lands, it slides down onto the next shingle, then the next, and drips right off the edge. If they started at the top, the water would sneak underneath! Can you count how many roofs have a pointy triangle shape before the next corner?

Where do builders start putting shingles on a roof?
Show the answer
At the bottom. At the bottom! Some roofs, called flat roofs, still tilt a tiny bit so the rain can run away.
Domestic roof construction facts for kids
- Many modern roofs are framed with wooden trusses made ahead of time, held together with metal plates.
- Even flat roofs slope a little so water runs off.
- In windy places, metal ties hold each truss down during big storms.
Questions kids ask about Domestic roof construction
What are roof trusses?
Trusses are wooden triangles that hold up a roof, and many are built in a factory and lifted up by a crane.
Why do shingles overlap?
Each row lies over the row below it so rain slides from shingle to shingle and off the roof.
Why do builders start shingles at the bottom?
Starting at the bottom lets every higher row cover the one below, so water can't sneak underneath.
