Sheet Roofing for Commercial & Agricultural Buildings
Our experienced team installs, replaces and repairs sheet roofing on farm buildings, storage facilities and industrial units.
Using box profile metal sheets, insulated panels or fibre-cement systems, we provide practical coverage perfectly suited to the building’s purpose.


When do you need commercial sheet roofing repair or replacement?
Over time, sheeted roofs can develop issues such as:
- Surface corrosion or breakdown of older metal sheets
- Loose or lifted sheets following severe weather
- Failed fixings leading to movement and leaks
- Persistent condensation inside livestock or storage buildings
- Ageing fibre-cement sheets showing wear or cracking
If the damage is localised, individual sections can often be repaired or swapped out. Where deterioration is more widespread, renewing the whole system is usually more effective than repeated patch repairs.

Our commercial sheet roofing services
Our work includes:
- New metal box profile roofing
- Insulated panel systems
- Fibre-cement installations
- Full roof renewals
- Targeted sheet replacement
- Integration with existing cladding and guttering
We handle sheet roofing for farm buildings and industrial units that need wide, uninterrupted internal space. In many cases, we renew sections in stages as they wear, rather than replacing everything at once.

Why choose commercial sheet roofing?
- Faster to install than most alternatives – less downtime on buildings that need to stay operational
- Over-roofing is possible in some cases, fixing leaks and improving
- Insulated sheets are worth considering where condensation is a persistent issue
Specification depends on building use and site conditions. We recommend solutions that suit the building, rather than a one-size-fits-all system.
FAQ’s
Is sheet roofing generally more cost-effective than other metal systems? +
It’s often the most practical choice where large areas need to be covered efficiently. Box profile sheet systems are typically lower in material and installation costs than standing seam, making them well-suited to agricultural and industrial buildings where coverage and longevity matter more than aesthetics.
Is sheet roofing suitable for places with high internal humidity? +
It can be, but condensation control and ventilation measures may be required depending on the building’s use.
Can new sheet roofing be installed over an existing one? +
In some cases, yes. This depends on the condition of the existing roof and load capacity, but we can assess this.
Do you remove and dispose of old roofing sheets? +
Yes. Safe removal and disposal of existing materials comes within our project scope.
