PVC Roofing: All You Need To Know About It
PVC as a material has become increasingly popular in the last 10 years. Given that the roofing industry is at the forefront of innovation and is always looking for new solutions, it was only a matter of time until manufacturers started incorporating PVC in their products.
This is especially true when it comes to single-ply roofs. There are lots of reasons why you should choose them including strength and durability, resistance to elements as well as chemicals. PVC roofs are an incredible solution both for your home and business and they are bound to last for a long time.
Another reason why PVC roofs have become popular is because you can easily put an eco-roof over it. Given that we are growing as a human kind and ecological, clean solutions have become a must, it is obvious that you would prefer to have such a roof yourself.
But let’s go a bit deeper and analyze all the pros and cons of these roofs. Read on!
Pricing of PVC Roofing
Although people usually start by inquiring about pricing, there is much more to be considered when buying a new flat PVC roof. This is why the price range of between $6 to $9.50 isn’t as high as you might think.
This pricing refers to a mechanically attached residential PVC membrane. It is used to measure how much a homeowner with a flat or low-slope roof needs to pay. If you also include removal of the previously installed roof, the price may go even higher.
Nevertheless, for the quality you’re getting, it is a much better option than going for something cheaper (such as asphalt roof) and having to change it or repair it after a few years. With that being mentioned, we come to the next important feature of the product.
No matter what kind of a roof we’re talking about, seams play a big part in both pricing and quality of the item. The same goes for PVC roofs.
Main reason why PVC roofs are so great is because of their hot air welded seams. Due to them, PVC roofing membranes are extremely resilient and cannot be penetrated by moisture. Bond that is created in the process is much more durable than the membrane itself which adds another layer of durability to the final product. In fact, if you have any experience with roofing systems you know that seams are usually the biggest issues as various unreliable materials such as tapes, caulks and adhesives are used to seal them.
Now, when we mention strength, you probably think that this is the same thing as durability but it isn’t.
In this case, strength is used to measure the products ability to resist breakage. According to ASTM (The American Society of Testing and Materials), PVC roofs have the ability to withstand up to 350 pounds of pressure per inch until finally breaking. By comparison, the standards require that a roof is able to take 200 pound of pressure per inch. This means that PVC roofs are almost twice as durable as the standards require.
In other words, they can take almost any kind of a punishment including that caused by severe storms.
Considering this product’s durability and strength, it is only normal that this material is among the longest lasting on the market.
For example, most roofs will last for about 10 to 15 years. Roofing contractors recommend that you consider changing it after 8 to 9 years. At best, you should at least perform some maintenance along the way.
Not with PVC roofs. The roof membrane can last more than 20 years which is quite amazing. As previously mentioned, this is one of the reasons why the price of the item isn’t as high as the numbers may indicate. This can especially be beneficial if you have a commercial property as you can rest assured that the production process will remain intact for years to come.
While durability and strength are great, most business owners are interested in roof’s ability to resist various substances. This is especially true in case on industries that are working with volatile components. So, let’s see how PVC roofs react when confronted with fire, chemicals, wind and water.
Chemical resistance can be a major factor why a company would pick one roof over another. Needless to say, with PVC roofs you get another layer of protection both for your structure and employees working in it. But it doesn’t stop there. Besides strong chemicals, the material is resistant to things such as animal fat which is common in restaurants. These vapors can be disastrous for asphalt shingles but they don’t do anything to PVC.
Fire is always an issue when it comes to roofs. This is precisely why you never see traditional northern wooden roofs in hot climates. Using a flammable material for industrial roof can lead to a cascade effect. If you have several properties or if you’re close to other factories, this can lead to a chain reaction. Not only is PVC hard to ignite but it also burns slowly. If you manage to remove fire as well as its source on time, the roof will self-extinguish itself. To put your mind at ease, PVC membranes have passed UL and FM fire testing making them an ideal solution both for your home and industrial facility.
Lastly, we need to mention how PVC reacts to strong winds. As you can presume, durability and strength play a major role when it comes to wind resistance. Both of these factors make is so that PVC roofs are hard to move. In fact, in practice they can even resist strong hurricanes making them an ideal item for coastal areas. Furthermore, you can use this roof for high buildings.
Even though these resistances are great and all, rainwater is always our main concern. In the end, if a roof cannot protect you from bad weather, what’s the point of it? Luckily, PVC is watertight in extreme weather conditions. It reacts well to high moisture, strong rain and variable alkaline conditions. Because of that, plant organisms have no way of surviving on top of this material. Not only is this one less concern but will cost you less in a long-term maintenance.
Today, when measuring product’s quality, most people will focus on its environmental impact. So, if you’re interested in going with something that has beneficial features, you should definitely consider PVC roofs.
First and foremost, these roofs are great way to save energy. They are highly reflective meaning that you won’t have to use AC as much. If you have a proper insulation, this kind of a roof can also save you money during winter.
Once a roof runs its course, you can easily recycle it which is additional eco benefit.
Should you buy a PVC roof?
As you can tell based on this article, PVC roofs are a viable option whether you’re a manufacturer or a regular homeowner. But the most important question remains: should you give it a chance?
Because of its amazing resilience, PVC can provide protection for various industrial buildings. It is also amazing against moss and other plant life. Due to these factors, your flat or slopped roof will always look good even without maintenance. This is a big thing to consider as you wouldn’t like to be represented by bad-looking facilities.
Its environmental impact also shouldn’t be understated. As a company, you want to save money wherever you can without jeopardizing business operations. PVC roof can help you with that. With its amazing features, it will save you a lot of money over time on heating or cooling. All that being said, this product is ideal for lots of different manufacturing businesses as well as company offices.
When it comes to residential buildings, the story is a bit different.
Positive aspects still remain no matter what. PVC provides security, it saves money and you won’t have to invest a lot in the future. Unfortunately, it isn’t always ideal in terms of design. If you have money and you want your home to look nice, there are better alternatives to it. It is also not the cheapest product on the market (although it does pay off in time) so you might want to consider some other alternatives if you don’t have enough money.
