Plastic is used in roofing for a variety of reasons. Plastic roofing sheets are made from polycarbonate, a durable thermoplastic material that can withstand high temperatures for long periods of time. They are also weather and water-resistant, preventing leaks and water-related structural damage. Plastic roofing is also lightweight, easy to install, and low maintenance, making it a popular choice for industrial and commercial buildings. Additionally, plastic roofing can be designed to resemble other materials such as glass or wood, offering a range of aesthetic possibilities. On the other hand, some homeowners have reported issues with condensation and dampness when plastic sheets are used as an underlay beneath roof tiles. In some cases, the plastic film is used to cover adhesive at the top of shingles during installation, though it is supposed to be removed afterward.

What You'll Learn
Plastic roofing sheets are made from polycarbonate
Polycarbonate roofing is highly versatile, suitable for both commercial and residential buildings. It is commonly used in industrial warehouses, decks, garages, patios, sheds, and conservatories. Polycarbonate roofing is also a popular choice for greenhouses due to its high light transmission and robustness. The ability to withstand harsh temperatures without degradation gives polycarbonate roofing a high life expectancy.
Polycarbonate roofing is available in various colours and configurations, making it aesthetically pleasing and customizable to different structural dimensions. It is easy to install, low maintenance, and highly energy efficient, resulting in long-term cost savings for homeowners. Polycarbonate sheets also offer excellent protection against external elements such as UV rays, wind, rain, and snow.
One notable advantage of polycarbonate roofing is its impact resistance and durability. It is virtually unbreakable, providing enhanced security and protection against vandalism and accidental damage. Additionally, polycarbonate roofing is fire-resistant, earning a Class-A fire resistance rating, the highest available. This feature ensures that polycarbonate roofs can protect properties from fire spread and potential structural destruction.
While polycarbonate roofing offers numerous benefits, there are a few considerations to keep in mind. Polycarbonate is prone to scratches and expands slightly with temperature changes. However, with proper installation considerations and polishing techniques, these issues can be mitigated. Overall, polycarbonate roofing sheets provide a durable, versatile, and cost-effective roofing solution for a wide range of applications.

Plastic roofing is weather and water-resistant
Plastic roofing is a popular choice for a variety of structures, including industrial complexes, commercial buildings, and residential roofing. One of the key advantages of plastic roofing sheets is their weather and water resistance.
Polycarbonate, the most common material for plastic roof sheets, is a durable thermoplastic that can withstand extreme weather conditions. Its ability to withstand high and low temperatures over extended periods makes it ideal for structures in regions with fluctuating climates. This feature also prevents pest infestations by blocking entry points for rodents, insects, and animals.
The water-resistant properties of plastic roofing sheets are crucial in preventing water retention and the associated issues. Unlike other roofing materials, plastic roofing is not susceptible to the development of mold, fungus, mildew, leaks, or other water-related structural damages. This feature ensures the longevity of the roof and protects the building's structural integrity.
Additionally, plastic roofing sheets offer versatility in terms of aesthetics and functionality. They can be designed to resemble other materials, such as glass or wood, providing a range of visual options. Plastic roofing sheets are also available in various configurations, colours, and thicknesses, allowing customization to meet specific roofing dimensions and requirements.
The ease of installation and affordability of plastic roofing sheets further contribute to their popularity. They are lightweight and require less manual labour during installation, resulting in reduced labour and shipping costs compared to traditional roofing materials.

Plastic roofing is a good alternative to felt
Secondly, plastic roofing offers enhanced protection against the elements. Unlike felt, which can absorb moisture and is vulnerable to leaks, plastic roofing is water-resistant and can prevent the development of mould, leaks, and other water-related structural damage. Additionally, plastic roofing can withstand extreme weather conditions, including heavy rains and strong winds, providing superior weather resistance compared to felt.
Another advantage of plastic roofing is its versatility and customisability. Plastic roofing sheets can be designed to resemble other materials such as glass or wood, offering a range of aesthetic possibilities. They can also be easily customised to fit various structural dimensions and angles, making them suitable for different types of buildings, including industrial complexes, commercial buildings, and residential homes.
Furthermore, plastic roofing is often lightweight and easy to install, saving time and money on manual labour. For example, PVC roofing is lightweight, low maintenance, and highly suitable for greenhouses due to its high sunlight transmittance. Acrylic roofing sheets, made from recycled plastic materials, are not only eco-friendly but also highly customisable to fit different structural angles.
Lastly, plastic roofing provides superior fire resistance compared to felt. Thermoplastic roofing materials have a Class-A fire resistance rating, the highest rating available, ensuring enhanced protection for your property in the event of a fire.

Plastic film covers adhesive at the top of each shingle
Plastic film covers the adhesive at the top of each shingle to prevent them from sticking together while in the package. This plastic film is not meant to be removed and is often quite difficult to remove. It is designed to dissolve itself with the heat of the sun in less than a year. When the shingles are nailed in place, the plastic film on the successive shingle course will no longer be in contact with the adhesive sealant strip on the upper surface of the lower or previous shingle course.
The plastic film is also known as a release film, cellophane strip, or protective strip. It is stuck to the bottom of the shingle, just lined up with the adhesive strip when they are stacked in a package. When the shingles are spread out on the roof, the strip does not line up with the adhesive, and the adhesive can do its job. The plastic film is offset from the adhesive strip, so it does not need to be removed before installation.
The use of plastic film to cover the adhesive on shingles is a common manufacturing practice. It protects the adhesive from activating while the shingles are in the bundle. This allows for easy transportation and storage of the shingles before installation. The plastic film also helps to keep the thickness pattern right up the roof and adds to the wind resistance of the shingles.
While the plastic film on shingles is generally not supposed to be removed, there may be cases where it was not installed properly, and it is fluttering in the breeze. In such cases, it can be easily ripped off or removed by a roofer. However, it is important to note that the absence of a starter strip and improper trimming of the shingles can be more concerning and may require corrective action.
