What Are Plastic Roofing Sheets Called? A Complete Guide to Plastic Roofing Terminology

If you’ve ever shopped for roofing materials, you’ve likely encountered a confusing array of names: PVC sheets, UPVC roofing, resin roof tiles, synthetic roof tiles, vinyl roofing, polycarbonate panels—the list goes on. So what are plastic roofing sheets actually called?

The short answer is: plastic roofing sheets go by many different names depending on the material composition, manufacturing process, intended application, and regional terminology. The most common umbrella term is simply “plastic roofing sheets” or “plastic roof panels”. But beneath that broad category lies a diverse family of products, each with its own specific name and set of characteristics.

This guide breaks down the most common names for plastic roofing sheets, helping you understand the terminology so you can choose the right product for your project.

PVC and UPVC Roofing Sheets

PVC roofing sheets (Polyvinyl Chloride) are among the most widely used plastic roofing materials. They are also referred to as:

• PVC roof sheets – the most common shorthand

• Vinyl roofing – a general term for roofing made from PVC

• PVC membrane or PVC single-ply – especially for flat or low-slope roof applications

• Polyvinyl chloride roofing – the full technical name

UPVC roofing sheets (Unplasticized Polyvinyl Chloride) represent a higher-grade version of PVC. The “unplasticized” means no plasticizers have been added, making the material stronger, more chemically resistant, and more dimensionally stable than standard PVC. UPVC roofing is often called:

• UPVC roof sheets

• uPVC corrugated sheets

• Vinyl roofing (though this term is increasingly used to refer specifically to UPVC)

PVC and UPVC roofing sheets are prized for their affordability, versatility, and durability. They do not rot or corrode, are lightweight and easy to install, and require very little maintenance. Common applications include garages, sheds, agricultural buildings, and industrial facilities.

Resin Roof Sheets

Resin roof sheets—also called resin roofing tiles—are another popular category of plastic roofing. In the roofing industry, “resin” refers to a synthetic polymer material—typically a high-grade thermoplastic—formulated to be rigid, weather-resistant, and durable.

Common names include:

• Resin roof sheet

• Resin roof tile

• Synthetic resin roof sheet

• ASA resin roofing tiles (ASA stands for Acrylonitrile Styrene Acrylate)

Resin roof sheets are engineered to mimic traditional roofing materials like clay, concrete, or slate while offering superior performance. They are lightweight (weighing only 2–6 kg per square meter—about 10–20 times lighter than clay tiles), UV-stabilized, impact-resistant, and available in a wide range of colors and profiles. They also offer excellent waterproofing, fire retardancy, and resistance to chemicals and corrosion.

Synthetic Roof Tiles

Synthetic roof tiles—also known as composite roof tiles—are plastic roofing products designed to replicate the appearance of natural roofing materials. These are often called:

• Synthetic roof tiles

• Composite roof tiles

• Plastic tiles

• Polymeric roofing tiles

Synthetic tiles are generally designed to imitate slate, clay tiles, or wood shakes. They achieve their color through synthetic dyes added to the plastic during manufacturing and are produced through injection molding. Common styles include synthetic slate, synthetic shake, and synthetic barrel tile.

These tiles offer the aesthetic appeal of premium materials like natural slate or clay without the drawbacks of excessive weight and fragility. They are lightweight, durable, and significantly easier to install than their natural counterparts.

PVC Panels for Ceilings

For interior applications, PVC panels—also called PVC ceiling panels—are a popular choice. These are typically referred to as:

• PVC ceiling panels

• PVC wall panels

• PVC foam boards (for certain variants)

PVC ceiling panels are available in various finishes, including glossy, sub-glossy, high-glossy, and transfer-printed designs. They are waterproof, low-maintenance, and offer a clean, modern appearance suitable for both residential and commercial spaces.

Other Plastic Roofing Materials

Beyond the categories above, several other plastic roofing materials have their own specific names:

• Polycarbonate roofing sheets – often referred to as polycarbonate sheets or plastic roofing sheets; known for being lightweight and impact-resistant

• Acrylic sheets – also called Perspex sheets or PMMA sheets; offer high clarity and weather resistance

• FRP roofing sheets – Fiber-Reinforced Plastic sheets, used for skylights and translucent roofing applications

• HDPE roofing sheets – High-Density Polyethylene sheets, available in corrugated or smooth profiles

How to Choose the Right Plastic Roofing Sheet

With so many names and options available, selecting the right plastic roofing sheet comes down to understanding your specific needs:

For outdoor roofing applications, PVC/UPVC roofing sheets and resin roof sheets offer excellent weather resistance and durability. For projects requiring a traditional tile appearance, synthetic roof tiles provide the aesthetic without the weight. For interior ceiling applications, PVC panels are a versatile and cost-effective solution.

Whether you call them plastic roofing sheets, PVC roof sheets, resin roof tiles, or synthetic roof tiles, one thing is clear: modern plastic roofing materials offer a combination of durability, lightweight construction, low maintenance, and aesthetic versatility that traditional materials simply cannot match. Understanding the terminology is the first step toward making an informed choice for your next roofing project.
