I've got a couple of tiles missing on the very top front point of my roof (3 floors up so really needs scaffolding) -I had them replaced as an insurance job but unfortunatley 2 days after I paid the cowboys (cheapest quote!) who did it the tiles slipped again. They refuse to go back up unless I supply scaffolding -they used a ladder for the job - so I'm stuck - anyone know the best way to find cheap scaffolding or anyone know a reliable roofer in SW London?? Its such a small job that its hard to get anyone's interest.
