Metal Roofing Sheets

Common Questions About Metal Roofing Sheets

What Are These Roofing Sheets Made From?  

Metal roofing sheets are typically produced from steel, aluminium or tin. But due to how well steel handles tough weather, it is the preferred materials amongst brands such as Britmet and Corotile. For this reason, the majority of our metal roofing sheets 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.

Granules 

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

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 

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? 

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.   

Are Steel Roofing Sheets Suitable for Cladding?

Both box profile and corrugated steel roofing sheets can be fitted vertically and used as cladding. This makes them suited for cladding a variety of buildings, such as agricultural shelters, industrial facilities, and commercial warehouses.

They are also available in a choice of polyester or PVC coating with both offering a selection of colours. Although this improves the visual appeal of your building, it also significantly improves the longevity provided by your cladding by up to 10 years.

Due to their profile, there is ample space beneath to insulate your cladding. Whilst PIR insulation is ideal, you may also be able to use natural alternatives such as wool insulation. Both of which will create a more comfortable and energy-efficient building.

How Do You Cut Metal Roof Sheets?  

Metal roofing sheets can be easily cut with both manual and powered tools. For an easy and short cut, you should use either tin snips or a nibbler. For a faster and longer cut, a circular saw will be more effective.

Whichever method you prefer, ensure you have the necessary safety equipment. This includes safety glasses, dusk mask, and work gloves. You should also ensure you have a stable workbench with clamps.
