This page is specifically about roof overlay and over-roofing as an alternative to stripping the old roof where the existing building is suitable.
Industrial roof overcladding can be used on suitable ageing metal roofs where a new external roof layer can extend service life, including appropriate factory, warehouse and commercial roofs across Glasgow, Edinburgh, Lanarkshire and wider Scotland.
Overcladding is not suitable for every building. The correct answer depends on the existing roof condition, structure, drainage, access, rooflights, gutters, fixings, detailing and the level of disruption the client can tolerate.
Modern Roofing checks the existing roof properly before recommending overcladding, refurbishment, targeted repair or replacement.

Modern Roofing provides industrial roof overcladding in Scotland for suitable factories, warehouses and commercial metal roofs where the existing roof and structure can support a new external weathering layer.
This page is specifically about roof overlay and over-roofing as an alternative to stripping the old roof where the existing roof is suitable.
A new roof covering installed over a suitable existing roof, usually with new support rails and roof sheets or panels.
It can suit certain older metal or asbestos cement roofs where the structure, access and roof build-up allow it.
Structural capacity, roof condition, fixings, gutters, rooflights, insulation, detailing and safe access.
On the right building, overcladding can provide a practical route between repeated repairs and full roof replacement.
Less strip-out than full replacement on suitable roofs, helping reduce disruption inside the building.
A new outer weathering layer can improve roof performance and protect the ageing roof beneath.
The project can include insulation, rooflights, gutter works and detailing improvements where appropriate.
The wrong roofing route costs more in the long run. These are the practical options Modern Roofing helps clients compare.
| Option | When it makes sense | What to check first |
|---|---|---|
| Targeted repair | Defects are localised and the wider roof is still performing. | Source of leak, substrate, access and whether the repair will actually hold. |
| Refurbishment | The roof has several issues but may not need full replacement. | Drainage, sheet condition, rooflights, details and system suitability. |
| Overcladding | The existing roof and structure can support a new external roof layer. | Structural capacity, fixings, insulation, gutters and rooflight strategy. |
| Replacement | The roof is at end of life or unsuitable for repair/refurbishment. | Programme, strip-off risk, internal protection, materials and budget. |

Overcladding is not something that should be sold from a photograph alone. The existing roof has to be checked properly, the structure has to be suitable, the drainage has to be understood and the finished system has to be detailed correctly around rooflights, gutters, edges, penetrations and flashings.
Modern Roofing checks the existing roof condition, structure, drainage, access and weak details before recommending overcladding as the correct route.
On suitable industrial roofs, overcladding can avoid the disruption of stripping the full existing roof while still creating a new external weathering layer.
Good overcladding is about more than new sheets. Gutters, outlets, rooflights, penetrations, flashings and edge details all need to work as one system.
No. The existing roof and structure must be checked before overcladding is recommended.
Some asbestos cement roofs may be suitable for overcladding, but the survey, structure, access and specification are critical.
