Frequently Asked Questions About Metal Roofing

Corrugated roofing sheets are an increasingly popular option for securing and sheltering industrial facilities and bespoke housing alike, and it is not necessarily difficult to see why.

With metal roofs lasting longer, being more stable and often more affordable than traditional shingle or asphalt roofs, corrugated iron is not only a popular alternative but in countries such as New Zealand a symbol of fashionable design and heritage.

Because of the interest surrounding metal roofing, here are some of the most commonly asked questions on the subject of roofing.

Are There Any Restrictions To Where Metal Roofs Can Be Used?

There is an assumption that a metal roof is heavier than other types of roofing solutions, but this could not be further from the truth.

A pitched roof with asphalt shingles is twice as heavy as a metal roof, whilst a slate or concrete tile roof is as much as four times the weight.

In short, metal roofs are an exceptionally versatile solution and can be used for any build that other types of roofs could be used on.

What Is The Average Lifespan?

Typically shingle roofs last between 15 and 25 years, depending on condition and maintenance, whilst a metal roof can last as long as 60 years depending on environmental conditions and maintenance.

It is entirely possible, therefore, for a metal roof to last a significant part of the lifespan of the people who live under it.

Do You Need To Remove The Old Roof?

Some people want to, or in some cases need to keep their old roofing work intact, but would still like to enjoy the benefits of a metal roof.

Thankfully, due to its lightness, sturdiness and ease of construction, a metal roof can be installed on top of the old one.

This is not necessarily recommended without a thorough inspection of the old one, as any problems to the wooden frame of your roof would be far harder to inspect and fix than it would be with only one roof.
