Common Questions About Metal Roofing Sheets

What Are These Roofing Sheets Made From?

Metal roofing sheets are typically produced using steel, aluminium or tin. Due to the impressive weather resistance, durability and structural strength of galvanised steel, it has become the preferred sheet material amongst leading brands such as Britmet and Corotile. For this reason, you will find that the majority of metal roofing sheets that we stock are manufactured from galvanised steel.

There are several benefits to steel roofing besides its resistance to corrosion caused by weather. Firstly, it is able to withstand significant loads from falling debris or snow. It also reflects solar radiant heat, therefore reducing the temperature below by up to 25%. Lastly, it can be recycled at the end of its long lifespan.

To further the lifespan of our steel roofing sheets they are coated with either granules, polyester or PVC. Besides offering more kerb appeal, this protects the steel beneath from corrosion and ultraviolet. In some cases, these coatings can squeeze an extra 10 years of use from your metal roofing sheets.

Are Steel Roofing Sheets Coated?

Whilst steel is an incredibly tough material, it is not naturally resistant to rust. We, therefore, use a zinc coating in most of our sheets to prevent water and oxygen from causing corrosion and, therefore, extending the lifespan. 

Many of our metal roofing sheets are available with other coatings, such as granules or polyester. These act as an additional barrier from the elements, combating premature corrosion as well as preventing scratches.


Some of our most popular metal roofing sheets feature a granule coating, such as our tile effect panels. These granules do not offer added protection from the weather, but also provide a more rustic appearance and increase sound absorption. 


Polyester is typically thought of as a fabric. However, this synthetic polymer can be found in many forms and is resistant to most chemicals. Because of this it can be found on railway lines, household appliances and more.

Several of our metal roofing sheets are available with a polyester coating, such as our box profile and corrugated sheets. Once coated with polyester, you can expect these sheets to last between 10 – 15 years with virtually no maintenance.

You’ll be delighted to hear that polyester coated sheets cost the same as uncoated sheets. Yet you benefit from the additional chemical resistance and choice of colours, such as juniper green and slate blue.


Plastisol has been used in electrical applications for decades. But this rubberised material now appears on an increasing number of roofing materials due to its resistance to corrosion as well as its ability to withstand impact damage.

Many of our metal roofing sheets can be purchased with a plastisol coating, such as our box profile and corrugated sheets. When coated, these sheets offer a lifespan between 15 – 25 years without the need for regular maintenance.

Polyester coated sheets cost around 25% more than polyester coated sheets. However, you can expect them to last up to 10 years longer and, therefore, provide far greater value for money in the future. 

How Much Do Metal Roof Sheets Cost?

Costing as little as £7 per square meter, metal roofing sheets are generally a very cost-effective roofing solution. Box profile and corrugated sheets are some of the most affordable variations and are pretty long-lasting so worth the initial cost in the long term.

Tile effect panels are slightly pricier, costing up to £15 or more per square meter. However, due to the coverage of this type of sheet, they are far quicker and easier to install than many alternatives so are less costly in terms of labour.

Can Steel Roofing Sheets Be Used As Roof Cladding


Box profile and corrugated metal sheets are very versatile materials. As well as roofing applications, they can also be fitted vertically and used as cladding, installable onto an array of buildings such as agricultural shelters, commercial warehouses and industrial facilities.

They are available in various coloured polyester and PVC coatings to stylishly enhance the look of a building and offer great curb appeal. These coatings also help to improve the longevity of the cladding by up to 10 years.

Due to the profile of metal sheets, there is ample space beneath for insulation. Whilst PIR insulation is ideal, you may also find that natural alternatives such as wool insulation may be a better fit for you. Whichever you choose, both will help to create a more comfortable and energy-efficient building.

How Do You Cut Metal Roof Sheets?


Metal roofing sheets can be easily cut using both manual and powered tools. For an easy and short cut, we recommend using either tin snips or a nibbler. Alternatively, if you want a faster and longer cut, a circular saw will be more effective.

Whilst using any cutting method, you must always ensure that you are wearing the appropriate safety protection gear. This includes safety glasses, a dust mask, work gloves and sensible shoes/clothing. You should also be using a stable workbench with clamps.

If you want to avoid the time and hassle of cutting your own metal sheets, take a look at our high-quality range of made to measure roofing sheets instead. These are carefully cut to your bespoke size prior delivery so all you have to do is fit them on arrival. Quick and easy.

How Much Do Metal Roofing Sheets Cost?

Metal roofing sheets can cost as little as £7 per square meter, with both box profile and corrugated sheets being the most cost-effective. If you would prefer a tile effect panel, however, you can expect to spend £15 or more per square meter.

But due to the coverage of these sheets, they are far quicker and easier to fit than many alternatives. Some even interlock with each other, making installation easy for both tradespeople and homeowners.

When buying roofing materials, it is important to consider both the cost of materials and labor time required. Calculating the cost per square meter also makes it far easier to compare the cost-effectiveness of different materials.

What Are The Problems With Metal Roofing?

When considering which roofing material to buy, it is always important to weigh up both the pros and cons of the product. Although metal roofing is generally very practical, durable and stylish, there are some drawbacks that you should consider before making the purchase.

In terms of weather resistance, metal roofing usually holds up very well. However, as with any metal surface, when impacted by heavy weight, it can sometimes be subject to denting and scratches. This may be an issue if you live in an area that experiences frequent heavy hail storms or if are installing to a building that may be subject to vandalism.

Although a lot of metal roof sheets have been cleverly designed to minimise the amount of noise they create, the bottom line is that metal is more noisy than other materials. In very harsh weather conditions, some may find the sound of rain and hail unpleasant or annoying which can often be heard through a metal roof.

Metal roofing is pretty affordable and far less expensive than other alternative materials. However, when looking at tile effect panels for example, these can reach up to £15 and higher which may be too expensive for those looking for a more cost-effective roofing project.

Do Metal Roofs Affect WiFi?

Wifi is a fundamental part of most modern households. This is why when many homeowners are considering roof materials, they may be concerned at the thought of a metal roof affecting the signal. But is this true or just a rumour?

Metal roofing is used commonly in a number of commercial buildings such as cafes, shops, restaurants and office buildings, all of which utilise wifi with seemingly no issues. The chances of the metal actually interfering with your wifi signal are very low, especially with the technological advances of wifi in the recent years. As long as your devices are in range of the router, then you should find no fundamental issues with the signal because of your roofing choice.
