Loft conversion scaffolds are taller, longer-running and need more care than a standard re-roof scaffold. The dormer carpenters need a generous platform to work off, the roofer needs edge protection right up to the new ridge, and the whole thing typically stays up for 8–12 weeks.
Typical project types
- Rear dormer loft conversions
- L-shaped dormers on Victorian terraces
- Hip-to-gable conversions
- Mansard loft conversions on period properties
- Roof-light only Velux conversions

Frequently asked questions
How long does a loft conversion scaffold need to stay up?
Most loft conversions run 8–12 weeks on the roof. We quote on that basis and offer weekly extensions if the build overruns.
Do you provide loading bays for trusses and steels?
Yes — we can include a loading bay sized for the materials your loft contractor needs to lift to roof level.
Can you scaffold a rear-only L-shaped dormer?
Yes — rear-only scaffolds with access via the side return are very common on Victorian and Edwardian terraces.
