1. 5 Types of Metal Sheet Roofing Materials - Pros & Cons vingle.net/posts/4543051 June 22, 2022 Metal roofing is becoming more popular with builders and homeowners alike by the day. They are easily adaptable to all types of buildings and are thus an easy choice for most. But with the increasing popularity, the variety of metal roofing available is also on the rise. Different materials with different benefits can be picked for sheet roofing of buildings - residential or commercial. The different types of materials available in the market are: Steel Roofing Sheets: This is the most commonly used among all metal roofing sheets. Aluminium Roofing Sheets: This sheet roofing is lightweight and corrosion-resistant. Zinc Roofing Sheets: This sheet roofing is expensive but long-lasting. Copper Roofing Sheets: The most expensive roofing sheet available in the market. Tin Roofing Sheets: This term is often used interchangeably with metal roofing. Metal sheet roofing is the new choice because of its adaptability to design and ability to handle all kinds of requirements. With the metal choices like steel, aluminium, zinc, copper and tin available, it can be challenging to decide the best type of sheet roofing for you. Let us talk about the difference between them and the pros and cons of each to help you make that decision. Steel Roofing Sheets: One of the most popular metals used for roofing is stainless steel, an alloy made up of iron and other elements. It has long been used in commercial infrastructure and is now becoming a common choice in household construction as well. Pros: It is lightweight and easy to install. It is rust-resistant resulting in quite a weather-friendly metal roofing sheet for your building. It is easy to maintain and long-lasting. 1/4

2. Cons: Factors such as material thickness, kind of finishing required and panel type can make stainless steel one of the most expensive materials to be used in roofing sheets. The sheet may be damaged or lose durability if it is not cleaned correctly. Aluminium Roofing Sheets: Aluminium is one of the most recommended metals for roofing sheets, particularly in coastal areas. It is extremely lightweight and is thus a preferred material when it comes to choosing metal roofing sheets. Although it is one of the lightest available materials, this does not make it proportionally the cheapest material as its ratio of weight to strength isn’t equal. Pros: Aluminium is corrosion resistant as well as rust-resistant. It is lightweight and easy to install. It is malleable and thus can easily be configured to suit most designs. It can also be easily recycled. Cons: Easy malleability may also result in easy denting of the roofing sheet. The roofing sheets need to be treated properly and carefully to avoid discolouration or fading. It can be more expensive because of its lesser strength-to-weight ratio. Zinc Roofing Sheets: Zinc roofing sheets often stand out aesthetically because of their appearance. Zinc undergoes a patination process over time, causing the sheet roofing to change colour and properties. It is one of the favourite materials with commercial builders when it comes to metal sheet roofing because of its longevity. Pros: Zinc is one of the most widely available metals with low toxicity. 2/4

3. It tends to cut down the cooling costs for buildings as sheet roofings made using zinc don’t absorb the sun’s heat like aluminium. It has comparatively easy maintenance as zinc has self-healing properties that help prevent it from corrosion and scratching. Cons: Zinc is quite expensive but its properties make it last much longer than the other metal sheet roofings. It needs to be treated and coated with protective materials from the underside. Otherwise, it will lead to corrosion. Chalking might occur, making it unappealing. Copper Roofing Sheets: Copper is one of the oldest metals in use to make the metal sheeting roof. It is a long- lasting material that undergoes the patination process, which gives it a unique appearance in terms of colour. Pros: Changing colour makes it an attractive material to use. It has the longest lifespan among all the metals used in sheet roofing. The green patina makes it rust and corrosion-resistant. It is 100% recyclable making it an environment-friendly metal. Cons: It requires careful installation, the absence of which may result in expansion and contraction of the roofing sheet. It is an expensive metal to pick but it comes with a lot of benefits. Due to its softer nature, it is prone to denting if debris falls upon the copper roof. Tin Roofing Sheets: The use of tin as a metal for roofing sheets began in the late 1800s but it became very popular really quickly. It remained a preferred choice of material for a long time until aluminium took over because of its many beneficial attributes. When you ask for metal 3/4

Pros: It is a very lightweight material, making it gain popularity so quickly when it was introduced. It is not complex to install. It is corrosion-resistant. It is as long-lasting as aluminium. Cons: Since it is no longer preferred for sheet roofing, it might be difficult to procure. Limited manufacturing will lead to making the material expensive. After detailing the use, pros and cons of all the available metals in sheet roofing, it should be a little easier to make a choice. Although, more often than not, the cost of the metal is the deciding factor. But in the case of roof sheetings, one may be urged to compare the cost of the metal to the benefits like availability, compatibility and longevity of the chosen metal to make a strategised decision.
