Today, business owners can be spoiled for choice when it comes to roofing systems. This includes a lot of options for construction materials. If you’re planning for a complete re-roof, you may want to consider the pros and cons of different membrane materials available. This article goes over the advantages and disadvantages of the most common roof materials for commercial buildings.
Pros And Cons Of Metal Retrofitting
If your building was originally constructed with a metal roof, you may want to consider a metal retrofit. This re-roofing method involves installing a new and more durable metal membrane will be installed over your original roof.
One of the biggest advantages of metal retrofitting is that it’s cost-effective. Rather than having your entire roof replaced at once, a metal retrofit can reuse your old metal roof’s insulation and insulation membrane. This can significantly save on cost for business owners.
Another major advantage to metal retrofitting is that it doesn’t require business owners to shut down their operations while the new roof is being installed. The original metal roof stays in place, protecting the building’s interior and allowing business operations to run normally. Temporary closure may be too costly for a lot of business owners, which makes metal retrofitting an attractive option for those who have slim profit margins.
Finally, another argument for going with metal retrofitting is that it’s considered eco-friendly. Because this re-roofing method doesn’t require you to take apart the original metal roof, you help reduce landfill waste.
However, for all the benefits of metal retrofitting, it does have one significant disadvantage. Retrofitting can extend your original metal roof’s life for up to 20 years. Compared to complete metal re-roofing, which can last anywhere between 30-60 years, the expected lifespan of metal retrofitting is quite short.
Pros And Cons Of PVC Membranes
Polyvinyl chloride (PVC) is a widely used membrane material. It offers great durability and longevity. It’s also highly regarded for its fire retardant properties, making it a very attractive option for warehouses and other industrial buildings.
PVC membranes are also advantageous, because of their durability against moisture, wind and chemicals. They are also resistant to tearing and puncturing.
Lastly, PVC membrane sheets often come in light colors and offer thicker insulation. These qualities allow for greater energy efficiency, reducing the cost of your business’s heating and cooling bills.
The main disadvantage associated with PVC membranes is that it can cost more than other materials discussed in this article. However, its durability and performance could make the initial cost worth it.
Pros And Cons Of TPO Membranes
Nowadays, Thermoplastic polylefin (TPO) membranes are a popular alternative to PVCs. They offer many of the same benefits like durability and resistance to moisture. The material is also lightweight, putting less stress on the building structure.
Another advantage to TPOs is that they’re very flexible. This property allows roofers to mold the material onto roofs with unique designs.
The main disadvantage to TPO membranes is that they haven’t been around as long as metal roofs and PVCs. They were first introduced in the 1980s, and are considered relatively new to roofing applications. However, they’re becoming more and more popular these days due to their cost-effectiveness, flexibility and durability.
Pros And Cons Of EPDM Membranes
Ethylene propylene diene methylene (EDPM) membranes are essentially synthetic rubber. The main advantage offered by EDPMs is their flexibility. These membranes can easily stretch and fit the form of any roof. They’re also highly durable and provide great weather protection.
Another advantage of EDPMs is that they don’t come with their own insulation, which gives business owners more options for insulation materials.
However, EDPM membranes can shrink with hot weather. Shrinking membranes can expose parts of the roof to water damage. To guard against this, it’s important to have EDPMs properly installed and maintained.
