Polycarbonate Sheet

Polycarbonate vs. Metal Roof: Which is Better?

Polycarbonate Sheets in CanadaRoofing is one of the most important components when it comes to commercial and residential property construction. These days, there’s no shortage of roofing system material options to choose from. Among the many options are wood, clay, stone, metal, and polycarbonate plastic.

The material you choose for your project depends on a number of variables such as structural requirements, local climate conditions, and the purpose of the property.

Out of all of the abovementioned roofing material options, metal and polycarbonate sheets are typically the top contenders that go toe to toe against one another. In this article, we’re going to explain why polycarbonate is better than metal.

Polycarbonate Roofs

Polycarbonate plastic sheets for greenhouse and gazebo roofs are far superior to metal for the following reasons.

Unmatched Durability

Polycarbonate sheets are the ideal roofing solution for virtually all kinds of mild or harsh weather conditions and they can withstand long-term exposure to heavy pressure or extreme temperature fluctuations.

Sound Barrier

Polycarbonate gazebo roof panels are not only resistant to strong vibrations from heavy winds and natural disasters, but also act as effective sound barriers. This is perfect for horticulturists who prefer a little peace and quiet when gardening or cultivating their plants.


Due to their lightweight nature, greenhouse polycarbonate sheets are extremely easy to transport, handle, and install. Moreover, they’re also easy and cost-effective to maintain long-term. Plus, polycarbonate sheets allow for even light distribution throughout your property and they’re well insulated so they allow for optimal year-round temperature control. This can help reduce your monthly energy costs and result in long-term savings.


Polycarbonate roof panels are incredibly versatile. They can be used as an effective glass replacement for a number of construction applications that require the emittance and even distribution of light. Greenhouses and conservatories are among the most popular commercial structures that incorporate the use of polycarbonate sheets.

Metal Roofs

Metal roofs are also gaining a lot of popularity in the construction industry. However, their positive traits and applications are quite limited for the following reasons.

Loud Noises

Every time there’s even the slightest inclement weather such as heavy rain, wind, or hail, you’re going to hear the pitter-patter of the impact hitting your roof incessantly from the outside. Metal roofs are prone to making loud echoing noises every time an object such as a bird hits against them and the sound of scratching on your roof can get irritating after a while.

Difficult Maintenance

Metal roofs are difficult and extremely expensive to maintain or repair. Because they typically come in one large piece, the entire structure needs to be removed whenever maintenance is required. They’re also more prone to denting inward if a strong projectile object hits against them during a big storm.

Industrial Unattractive Aesthetic

Metal roofs have a modern and extremely futuristic industrial aesthetic that can sometimes look like something out of the Jetsons. If that’s the look you’re going for, then this is a good choice for you. But be forewarned that your local HOA may be against it, especially if they’d prefer to maintain a uniform aesthetic throughout the neighborhood.
