Abstract: A wheeled scaffold for roofing materials has a framework for carrying the roofing materials. The framework includes a row of steps extending along the framework. First and second wheels are secured to the framework. The first wheels support the framework on roof purlins, while the second wheels are arranged to run along the upper side of the roof purlins. The first and second wheels can be adjusted to accommodate different spacings of the roof purlins. Work platforms are secured to a side of the framework, to enable a person to secure roofing materials in position without leaving the scaffold.
