Corrugated iron is relatively light, portable and adaptable, which made it ideal for some traditional construction. It was most frequently used for roofing and walling, and also for prefabricated buildings, especially in rural areas.
All metals corrode. So the main aim with a corrugated iron roof is to slow down how quickly this happens. Regular inspections can help you to spot and fix problems before they become serious.
Wetting and drying cycles speed up the decay of a corrugated iron roof. Trapped moisture caused by vegetation and clogged rainwater goods are common causes of problems with corrugated iron roofs, as is condensation build-up inside.
Reuse of original corrugated iron sheets is preferred over replacement, as the few firms making sheets today may be unable to match profiles and sizes. Patch repairs of existing sheets are possible.
Corrugated iron roofs are very much part of Scotland’s rural landscape. Traditional materials and colours should be used for over-painting sheets, preferably to match those originally used.
