Possible Dangers of Metal Roofing

Metal roofing may be one of the most widely used, durable and economical types of roofing on the market, but – like all building materials – it is not without a few dangers. However, these depend on a number of factors: the installation process, the maintenance performed, the environmental conditions, and the age of the roofing material. Here, we’ll take a look at the risks that you could run into with various types of metal roofing (hint: there aren’t many risks at all).

Different types of metal roofing

When people think of metal roofing, they tend to lump several completely different materials together under the umbrella term, and a range of misconceptions arise as a result. Metal roofing can be made from aluminium, steel, lead, copper or a number of other materials. Of these, lead is perhaps regarded as one of the highest-risk materials due to its toxicity, which can increase with age. However, because lead remains one of the toughest metals on the market, and correct management can ensure the safety of building occupants as well as the surrounding environment, it is still used today. Copper too, can be risky – but that is primarily because it is prone to theft!

The lightning question

Many building owners express concern about lightning striking their metal roof during a storm. This is a reasonable worry; after all, you know that metals conduct electricity, and you don’t want the occupants of the building going up in smoke. What we always explain to clients, however, is that a metal roof is no more likely to be hit by lightning than any other kind of roof, and if it were to be struck, the charge would more than likely disperse safely through the structure. Unlike wooden roofs and many others, materials like steel are not flammable – so there is no fire risk. If you still feel concerned, you can always install a lightning rod for 100% peace of mind.

Slippery when wet

The major risk with metal roofing, really, is when workers do installation or repair in wet weather conditions. This is because the surface can be slippery. As a result, work on the roof should only be done in calm, clear weather. However, that is a fairly obvious precaution to take in any kind of building work.

Reliable protection

Provided that correct maintenance is done on a metal roof, it should last many decades, providing reliable protection from the elements. Unlike shingle-based roofs, metals like steel tend to come in sheets, meaning that no fiddly bits need replacement.

Steel is one of the most affordable, safe types of metal roofing and is both easy to install and maintain. Coatings and galvanisation prevent corrosion, resulting in a roofing material that often outlives the building beneath. It can be recycled, too, making it a green choice.
