Roofing sheets are a very essential element of any roofed structure. They protect it from dust, pollution, harsh weather conditions and also give the structure a beautiful look. They are available in a range of materials each having its unique qualities and uses. Choosing the right kind of roofing sheet is an extremely important choice that will determine the lifespan and maintenance costs of your structure.
Some factors to consider while selecting a roofing sheet are the climate in which you are building, the colour options and energy efficiency. You should also make sure that you understand the warranty on your sheets as well as any additional costs like installation and maintenance.
When it comes to determining how many roofing sheets you will need to purchase the easiest way to do this is by dividing your roof area by the size of one sheet. For example if your roof is 6.0m long and you want to cover it with Suntuf Polycarb sheets (available in Greca or Diffused Grey) then this will work out at around 8 sheets. You will also need to take into account if you have a Gable or Hip roof as these will require a different number of sheets to cover the whole structure.
Another thing to keep in mind when measuring for your roof sheets is that you will need to allow an overhang of at least 60-70mm all the way round. This will prevent water from coming into contact with the rafters or purlins which can lead to damp or structural weakness in your roof. If your roofing sheets are not UV protected then it is important to store them away from direct sunlight which can cause them to fade or crack over time.
If you are looking for a more traditional roof covering then corrugated fibre cement sheets are a great option. These are incredibly versatile and can be used for both residential and commercial buildings. They offer a great deal of benefits including being lightweight, resistant to rust and corrosion and being easy to clean. Additionally, they have a high strength-to-weight ratio meaning that they can support a relatively thin supporting structure which will help to reduce the overall cost of the structure.
Metal roofing sheets are another alternative that can be considered as they come in a wide range of styles and colours. They can also be used for both a flat or corrugated roof and they are an excellent choice when it comes to keeping energy costs down. They are also anti-corrosive and can be easily repaired which will increase their lifespan.
Plastic roofing sheets are also a good option as they can be used for both residential and commercial projects. They are also available in a variety of colours and can be made to suit any design requirement. They are lightweight and can be easily cut to fit your requirements. They are also low maintenance and can withstand a variety of temperatures.
