Types of Roofing Sheets: Benefits and Selection

Roofs are like shields for your property; the type of roofing you have can make a big difference in its durability, visual appeal, and water and weather resistance. 

Roofing sheets are a broad term for various materials used to cover the roof of a structure. They come in different materials, designs, and sizes, each with unique properties and applications. At JJ Roofing Supplies, we stock high-quality roofing sheets in multiple sizes and finishes.

This blog will discuss the various types of roofing sheets available, why each is beneficial, and share tips on making wise choices. 

Whether you're a homeowner or a roofer, understanding roofing sheet types can help you make better decisions for robust and good-looking roofs that last.

Why Do You Need Roofing Sheets?

Picking suitable roofing supplies is crucial when building or renovating your building. It affects how long the roof lasts, how well it keeps the house comfortable, and how good it looks. 

Roofing sheets are popular because they're versatile and have many benefits.

• Material Variety: Roofing sheets are available in metal, polycarbonate, PVC, and bitumen, each offering unique properties and benefits.
• Weather Resistance: These sheets provide robust protection against various weather conditions, including rain, snow, hail, and UV radiation, ensuring long-lasting performance and shielding for the property.
• Design Options: The versatility of roofing sheets extends to diverse designs and styles, allowing homeowners and builders to choose the perfect aesthetic to match their roofing aesthetics.
• Cost-Effectiveness: Roofing sheets are often more cost-effective than traditional roofing materials due to easy installation and reduced structural support requirements. In addition, longevity translates into fewer maintenance expenses over time, contributing to overall savings.
• Installation Ease: The simple installation processes of roofing sheets save time and labour costs. Their lightweight nature also simplifies handling and positioning during installation.
• Low Maintenance: The low-maintenance requirements of roofing sheets make them an attractive option for those seeking a hassle-free roofing solution, reducing the need for ongoing upkeep and repair.

Roofing Sheets Types

At JJ Roofing Supplies, we offer a diverse range of roofing sheets, each distinguished by unique properties, purposes, and an array of shades.

Polycarbonate Roof Sheets:

Polycarbonate sheets, favoured by industrial and commercial roofers, offer durability and low maintenance, making them ideal for conservatories, sunrooms, decks, patios, and greenhouses. 

At JJ’s, we prioritise quality, sourcing these sheets from reputable brands like Aerial Plastics, Clear Amber, and Palram/Storm Building Products to ensure long-term reliability in challenging conditions.

• Costs: Polycarbonate roof sheets can be expensive but are generally more durable. Costs vary based on thickness, UV protection, and other features. Ideally, at JJ Roofing Supplies, polycarbonate sheets range from £5 to £500 per sheet.
• Life Expectancy: Polycarbonate sheets have a longer lifespan, ranging from 15 to 20 years, if installed correctly. 
• Weight: Polycarbonate roofing sheets are lightweight, making them suitable for various structures without putting excessive strain on the supporting framework. However, this type of roofing sheet doesn't support walking on it.
• Installation: Polycarbonate sheets are relatively straightforward and often available in interlocking systems for easier installation. Most brands also offer integrated roofing sheets systems, meaning all you need to install roofing sheets come in the integrated package. Check out our roofing sheet accessories.

Bitumen Roof Sheets:

While not a recent innovation, rigid and lightweight bitumen sheets remain a staple for roofing, renowned for their exceptional waterproofing properties. 

An added advantage lies in their ability to be coloured, with pigment infused for a lasting hue that eliminates the need for repainting. Essential for domestic and commercial rooftops, these sheets provide invaluable waterproofing during construction, safeguarding the structure from weather and water damage.    

• Costs: Bitumen roof sheets are often more budget-friendly. You can expect to pay around £10-£60 per sheet, depending on the finish and length. 
• Life Expectancy: Bitumen sheets have a moderate lifespan, typically 15-25 years, depending on how you keep them. Regular maintenance is essential to ensure the longevity and durability of bitumen sheets.
• Versatility: Bitumen sheets are commonly used in low-slope roofs and are known for their waterproofing properties.
• Weight: Bitumen sheets are relatively lightweight but not lighter than polycarbonate sheets, making them suitable for various garden structures.
• Installation: Installation of bitumen sheets typically requires twenty fixings and no specialist tools, and they are often available in rolls or shingles for easy application.

PVC Roof Sheets:

PVC roofing sheets have gained widespread popularity for their versatility and benefits. Crafted from polyvinyl chloride, these lightweight and corrugated sheets offer homeowners a cost-effective yet practical roofing solution. 

Their excellent light transmission makes them an affordable alternative to traditional roof lights, allowing abundant natural light indoors. Despite their affordability, PVC sheets maintain durability, ensuring a reliable and solid roofing choice.

• Costs: PVC roof sheets at JJ Roofing Supplies are sourced from Clear Amber and Aerial Plastics and can cost £20 to £400 per sheet.
• Life Expectancy: PVC sheets are not known for their longevity; hence, their lifespan remains 10-20 years when maintained and installed correctly.
• Weight: PVC sheets are lightweight, making them easy to handle and suitable for various property structures.
• Installation: Just like bitumen sheets, installation of PVC sheets is generally straightforward, requires twenty fixings and is often available in interlocking systems for ease of installation.

Fibre Cement Roof Sheets:

Fibre cement roofing sheets are famous for roofs on various buildings, from homes and sheds to agricultural and industrial buildings. They are made from a combination of cellulose fibres, cement, and sand, which are compressed and formed into corrugated sheets. This gives them several advantages over other roofing materials. 

At JJ’s, our fibre cement roof sheets come from Marley, which is exceptionally known for its high standards of roofing materials.

• Costs: The construction materials make fibre cement roof sheets more expensive than other roofing options. However, we provide these high-quality sheets at a competitive price range, from £25 to £35.
• Life Expectancy: Fibre cement sheets have a relatively long lifespan, lasting around 30-50 years or more, depending on the quality and maintenance.
• Weight: Fibre cement sheets are heavier than roofing materials, and proper support is required during installation.
• Installation: Fibre cement sheets may require professional expertise due to their weight and specific installation requirements.

Tile Effect Roof Sheeting:

Tile effect roof sheets offer a stylish alternative, combining the appearance of traditional tiles with modern construction benefits. Ideal for outbuildings, sheds, and commercial/industrial properties, they provide aesthetic charm, durability, and efficiency.

• Costs: Tile effect roof sheets can be more expensive than traditional metal sheets, ranging from £8 to £20 per sheet.
• Life Expectancy: Tile effect sheets offer a durable lifespan, lasting 40-50 years on average.
• Versatility: Tile effect sheets mimic the appearance of traditional tiles but offer the benefits of a lightweight and easy-to-install roofing solution.
• Weight: While heavier than other roofing materials, tile effect sheets are still lighter than actual tiles, making them a more feasible option for specific structures.
• Installation: Tile effect sheets may be more involved than standard metal sheets, but they are generally easier to handle than traditional tiles. The minimum pitch for tile effect roofing sheets can be as low as 12 degrees, which the traditional tiles hardly offer.

Acrylic Roof Sheeting:

Acrylic roof sheets are a modern and flexible roof choice for many properties. They're made from see-through acrylic materials and let natural light in while keeping the weather out. We stock acrylic sheeting from Ariel Plastics, known for its durable quality roofing sheets. 

• Costs: Acrylic roof sheet costs can vary based on thickness and brand. At JJ Roofing Supplies, our Acrylic Roofing Sheets costs start from £145.
• Life Expectancy: Acrylic sheets have a moderate lifespan, typically around 15-20 years. They may require replacement or maintenance, especially in harsh weather conditions.
• Versatility: Acrylic sheets are transparent, providing natural light making them suitable for applications like skylights and greenhouse roofing.
• Weight: Acrylic sheets are lightweight, making them easy to handle and install.
• Installation: Acrylic sheets are relatively easy to install, and their lightweight nature simplifies the process. However, proper sealing and care are essential to prevent leaks and extend their lifespan.

Metal Roof Sheeting:

Metal roofing sheets are commonly preferred for affordability, durability, and superior protection. Their versatility shines in withstanding extreme temperatures, making them ideal for frigid cold and scorching heat.

• Costs: Metal roof sheets can vary in cost depending on the type of metal used, with options like steel and aluminium. 
• Life Expectancy: Metal roofs are known for their durability and longevity. They can last 40-70 years or even more, depending on the specific metal, coating, and environmental conditions.
• Weight: Metal roofs are relatively lightweight compared to other roofing materials, which can simplify installation and reduce structural concerns.
• Installation: Metal roof sheets can be relatively straightforward, especially with modern interlocking systems. Professional installation is recommended to ensure proper sealing and longevity.

Selecting the Best Roofing Sheet for Your Property

Your roof’s durability and aesthetics depend on the type of roofing material you choose to build. You may want to consider many factors to make the best choice for your needs.

Weather: Look for the weather in your region. Each roofing material is suited to perform better in certain climates. For example, metal roofing sheets are excellent for areas with heavy rainfall or snow, as they are corrosion-resistant and offer superior durability.

House Style: Check the architectural style of your home. Some roofing materials, such as polycarbonate sheets, complement carport porches, while plastic or bitumen roofing sheets are more suitable for garden sheds and structures.

Cost: Budget is another crucial factor in deciding which roofing sheet suits your property. Decide how much you want to invest in your roof and explore materials within that price range. While PVC roofing sheets are cost-effective, metal roofing may have a higher upfront cost but offers long-term savings due to its durability.

Different Roofing Sheets for Each Property Type

1. Commercial or Industrial Roofs

If you want to improve the roofs of large factories or buildings, go for corrugated aluminium sheets. These sheets are great because they are strong, versatile, and don't get damaged easily. Plus, they have a coating that makes them need less maintenance, saving you money in the long run.

2. Storage Sheds or Utility Buildings

Consider using galvanised steel sheets for outdoor storage sheds or small utility buildings. These sheets are rigid and don't cost too much. They're a good choice if you want reliable protection without spending much money.

3. Sunrooms or Conservatories

If you're redoing the roof of a sunroom or conservatory, multiwall polycarbonate roofing sheets are a good option. They let in a lot of natural light and keep the temperature right. They make your conservatory a comfortable and well-lit space, balancing looks and practicality.
