A polycarbonate roof is an effective roofing solution that can last for decades depending on the type of roof, location and maintenance. Polycarbonate is an extremely durable material that is not only scratch-resistant but also UV-resistant, meaning it can last for many years without yellowing.
On average, a polycarbonate roof will last up to 25-30 years with proper maintenance, while some can even last beyond that. Weather conditions play a large factor in just how long a polycarbonate roof will last, as extreme wind, hail, heavy rain and large amounts of sun exposure can cause shortening of the life span.
Regular maintenance is always key to maximising the lifespan of a polycarbonate roof, as this includes checking for cracks and damage, removing debris from the roof, and cleaning it to remove dirt and debris at least twice a year.
Routine maintenance can help you get the most out of your polycarbonate roofing, ensuring a longer lasting material that is guaranteed to protect your property for many years to come.
What are the disadvantages of polycarbonate?
And these should be taken into consideration when deciding whether or not it is the right material for the job. First, though strong and lightweight, it can be easily scratched, dented, and cracked under pressure.
This can be attributed to its relatively low depth of impact, which is far less than other thermoplastic materials. Second, it is more prone to stress cracking from abrupt changes in temperature, ultraviolet light, or chemical exposure, and therefore needs to be protected from such factors.
Third, while it’s an excellent insulator, it is not the most effective material when it comes to keeping the temperature of a space comfortable. Lastly, it can be a bit on the expensive side when compared to other materials.
Can you walk on polycarbonate roof?
No, it is not recommended to walk on a polycarbonate roof because it is not designed to be walked on and its slippery surface can cause slips, trips and falls. Polycarbonate roofing is a strong and lightweight material that is commonly used in a range of applications, such as greenhouses, windows and shed roofs.
However, it is not designed to be walked on, therefore it is not considered a safe surface to walk on. With its smooth and slippery surface, it can cause slips, trips and falls and could result in significant damage to the roofing material.
Furthermore, walking on the material can put stress on the roof and weaken the bonding of panels. This, in turn, could cause air and water leaks, which can lead to additional roofing repairs, as well as additional costs.
For these reasons, it is not recommended to walk on a polycarbonate roof.
Is polycarbonate roofing flexible?
Polycarbonate roofing is indeed very flexible in comparison to other roofing materials. It is constructed from polycarbonate plastic, which is made of extremely thin sheets that are twisted together on an angle to create a strong and durable yet lightweight material.
Its flexibility allows it to be bent and molded into different shapes and sizes to fit different structures, and its pliable nature makes it the perfect choice for roofing projects that require curved lines or other special shapes.
In addition, its high impact resistance makes polycarbonate roofing strong enough to hold up to extreme weather conditions and other external forces. Polycarbonate roofing is also highly resistant to corrosion, heat, and ultraviolet rays, making it ideal for both indoor and outdoor projects.
Is it hot under a polycarbonate roof?
It is possible for a polycarbonate roof to become hot, depending on the climate and type of materials used in the roofing. Polycarbonate roofs are made from durable and lightweight plastic, which can offer protection against the elements.
In areas with direct sunlight, a polycarbonate roof can become warm and even hot to the touch. This is due to the material’s ability to absorb heat from the sunlight and act as an insulating material.
The degree to which the roof will become hot in direct sunlight will depend on the thickness, color, and type of the polycarbonate material used. Darker colors will absorb more heat and become hotter than light colors.
Additionally, thicker sheets of material will take longer to heat up but can become notably hot due to their increased surface area. The best way to regulate the temperature of a polycarbonate roof is to utilize lighter colors and/or increase insulation with insulating layers beneath the polycarbonate sheets.
How do I stop rain noise on polycarbonate roof?
The most effective way to stop rain noise on a polycarbonate roof is to add insulation to the space between the roof and the interior ceiling. This can be done by either spraying foam insulation directly to the underside of the roof, or by installing acoustic panels or other sound-absorbing materials in the attic.
If you decide to use foam insulation, you need to be careful that it does not block ventilation or any electrical wiring. To further reduce rain noise, you can also install a secondary layer of material such as acoustic batts, studded foam boards, or rubber mats.
This layer of insulation should be directly under the foam, so that the foam is acting as a barrier to reduce the impact of any rain drops.
In addition to insulation, you can also replace existing windows with double or triple-glazed varieties and add acoustic seals to them to further reduce any rain noise. Lastly, you can install acoustic doors and seal any gaps around them to ensure that any noise from the outdoors is kept out of the interior.
Will polycarbonate yellow over time?
Yes, polycarbonate is known to yellow somewhat over time when exposed to light, particularly sunlight. The yellowing is due to the breakdown of the polycarbonate molecules, which is caused when the ultraviolet (UV) radiation in sunlight breaks up their chemical bonds.
The yellow discoloration usually doesn’t affect the performance of the polycarbonate, but it can make it look unappealing. To prevent this, you can buy polycarbonate materials that have UV-stabilizers added to them, which help to protect the material from the effects of sunlight.
Additionally, it’s a good idea to avoid storing and using polycarbonate in direct sunlight, and to keep it covered if possible when not in use.
Does polycarbonate break easily?
No, polycarbonate does not break easily. Polycarbonate is a strong and tough thermoplastic that has excellent heat and impact resistance. It is an extremely durable and resilient material that can be up to 200 times stronger than glass.
Its high impact strength ensures that it does not easily break if it is dropped, and it is also more flexible than other types of plastics, allowing it to better absorb impacts. Its chemical composition provides excellent electrical, fire and shock resistance, further increasing its durability.
Additionally, polycarbonate won’t easily shatter or crack when exposed to extreme temperatures and weather conditions, making it an ideal choice for outdoor and commercial applications.
What is better PVC or polycarbonate?
The debate about PVC and polycarbonate is ongoing, and each material offers different advantages and disadvantages.
PVC is often chosen for indoor applications because it is relatively inexpensive and easy to fabricate, making it a great choice for creating complex shapes. It is weather and UV light-resistant, and relatively durable, making it great for outdoor applications as well.
However, PVC is not fire retardant, so it needs to be treated with an appropriate fire retardant if used outdoors.
Polycarbonate is strong and shatterproof, so it is often chosen for applications in which safety is a concern. It can be combined with glass or acrylic to provide extra protection, and it is highly durable and able to withstand extreme temperatures.
However, polycarbonate is heavier than other materials, and it is also more expensive than PVC.
In comparison, both PVC and polycarbonate have their own advantages and disadvantages, so the best choice for an application is highly dependent on the specific requirements for the project. For decorative applications, PVC is usually preferred due to its versatility and functionality.
For outdoor applications, polycarbonate is usually the better choice due to its greater durability, fire retardancy, and resistance to harsh weather and UV light.
Are polycarbonate roofs good?

What thickness polycarbonate should I use for pergola roof?
The thickness of the polycarbonate panel can vary and depend on a few factors such as the size of your pergola and the climate you live in. Generally, for pergola roofs the minimum thickness for polycarbonate should be 4mm.
The advantage of using thicker polycarbonate sheets is that they become more durable; however, with greater thickness comes added weight that needs to be accounted for in your pergola design. If you live in a warmer climate, you can use 6mm and above for additional shade.
But in addition to the thickness of the polycarbonate panel, it’s also important to look at other factors like the U-value, g-value, and the total energy transfer matter. The U-value measures insulation, so the lower the U-value the better the insulation, while the g-value measures the amount of solar radiation blocked, so the higher the better.
For the best results, aim for a U-value of 1.0 and a g-value of 0.85. In any case, make sure to consult a local contractor or engineer to get the best advice for your specific needs.
