What is Polycarbonate Roofing?

Polycarbonate sheets are commonly used for roofing applications due to their versatility and strength. Call us today on 01455 818317 for more information. 


As a strong thermoplastic material, polycarbonate roofing is lightweight and can withstand extremely low and high temperatures. 

With many benefits of using polycarbonate roofing sheets, they can be used in a variety of applications, including commercial, industrial and domestic applications. Polycarbonate is a popular material that can easily be used to your advantage, which is why the material is so commonly used as a cheap alternative to glass.

Our multiwall polycarbonate sheets, also known as structured polycarbonate, offer 30x the impact strength of standard acrylic sheets and over 250x the impact strength of glass at the equivalent thickness. 

With Multiwall, there is a tolerance of +/- 5mm in cutting. This does mean that we cannot guarantee the cutting will follow the line of the flutes.

The Benefits of Using Polycarbonate Sheets for Roofing

As polycarbonate is a versatile material that can be used for everyday projects, there are a multitude of benefits of using polycarbonate roofing sheets. Some of these benefits include:

- Strength

Polycarbonate roof panels are much stronger than glass, meaning that they are not only a safe option for roofing but also much easier to handle.

- Damage Resistant

Fortunately, polycarbonate sheeting offers fantastic protection against extreme conditions, including hailstones, rain and snow, as well as vandalism and accidental damage.

- Fire Safety

Polycarbonate roof panels offer incredible fire protection, meaning that the material will safely melt away from the flames in the unlikely event of a fire.

- UV Protection 

As polycarbonate offers fantastic UV protection, harmful UV radiation is blocked by up to 98%, making it perfect as roofing above hot rooms or where you’d like to reduce bleaching from the sun, for example, conservatory roofing.

- Low Cost

Compared to glass, polycarbonate roof panels are much more cost-effective and are also less likely to damage.

- Uses for Polycarbonate Sheets

Perhaps the most common use of polycarbonate sheets is for conservatory roofing, but also for patio roofing, greenhouse roofing, carport roofing and roofing for decked areas. 

Away from roofing, polycarbonate sheets are also used as an alternative for glass windows, and are commonly used for shed windows and bus windows.

- How to Cut Polycarbonate Roofing Sheets

Polycarbonate roofing sheets can easily be cut using a circular saw or jigsaw. At Sheet Plastics, when you purchase polycarbonate sheets with us, we’ll cut your material to size as required, making it easier for you to get to work!



Do plastic roofing sheets discolour?

Low-quality plastic roofing is susceptible to discolouring from UV exposure. However, high-quality plastic sheets include a UV-resistant coating that prevents discolouration, cracking, and weakening, even after prolonged exposure. 


How long does plastic roofing last?

If installed in a generally shaded area, they can last for 30 years without requiring replacement. Alternatively, if you fit them in direct sunlight, you can expect it to last 10-20 years. The quality of your plastic roofing and the frequency of maintenance will determine how long it lasts. 

How do you clean plastic roof sheets?

Harsh cleaners and power washers will cause the plastic roofing to degrade and cause damage that can shorten its lifespan considerably. So, using equal measures of mild soap and water is the most effective way to clean them. 

Does plastic roofing scratch easily?

No it does not scratch easily. But harsh weather conditions could pick up debris that could hit your pasltic roofing which may result in scratches.
