Stephen has come to repair an old roof. Some tiles are broken and need replacing. Before starting, he plans what to do. He wears a safety belt while he works. He carries new tiles onto the platform. With his friend, he removes the old tiles. They work carefully to avoid damage. The broken tiles are put into a bin. He lays a sheet to keep the rain out. Wooden strips hold the new tiles in place. Starting at the bottom, he lays new tiles. Each row sits just above the one below. He works upwards until the roof is covered. Stephen has finished and shows the owner. She smiles because the roof looks so good.
