Are you thinking about replacing or installing a roof for your store? If so, you may have heard about low slope roofing materials. These types of roofs are commonly used in commercial buildings, including stores.
But what makes them a good choice for your business?
In this blog post, we will dive into the pros and cons of popular low slope roofing materials. By the end, you will have a better understanding of which material is best suited for your store. Let’s explore these options together!
What Are Low Slope Roofing Materials?
Low slope roofing materials are designed for roofs that have a gentle slope. These types of roofs have a slope of 2:12 or less, which means the roof rises just 2 feet for every 12 feet it extends horizontally. These roofs are common in commercial buildings, including stores, because they are cost-effective and easy to install.
Built-Up Roofing
Built-up roofing (BUR) is a traditional and widely used material for low slope roofs. It is made by layering multiple sheets of roofing felt, which are then covered with hot asphalt or tar. This creates a durable, waterproof surface. BUR has been around for a long time and is still a popular choice today.
Pros of Built-Up Roofing
One of the main benefits of BUR is its durability. This type of roof can last for 20 to 30 years with proper maintenance. BUR is also highly resistant to water, making it a great choice for areas that experience heavy rainfall or snow.
Additionally, it provides excellent insulation, which can improve energy efficiency in your store. This is especially important in climates where the weather fluctuates between hot and cold.
BUR also has a solid reputation for being easy to repair. If any part of the roof gets damaged, it is relatively simple for a roofing contractor to fix the issue. The material is also known to require minimal maintenance, which saves you time and money over the years.
Cons of Built-Up Roofing
The main drawback of BUR is its weight. The layers of felt and asphalt can be quite heavy, which can add strain to the structure of your building. This is something you need to consider before choosing this material for your store.
Additionally, the installation process can be messy and time-consuming. It requires specialized equipment and skilled labor to install properly, which can increase the initial cost of the roof.
Synthetic Rubber (EPDM)
Synthetic rubber, also known as EPDM (ethylene propylene diene monomer), is a popular choice for low slope roofs. This material is a single-ply membrane that is made from rubber compounds. It is lightweight, flexible, and easy to install. EPDM is known for its long lifespan and ability to resist harsh weather conditions.
Pros of Synthetic Rubber
One of the biggest advantages of EPDM is its energy efficiency. The material reflects sunlight, which helps keep your store cool during the summer.
This can reduce your energy costs, making it an excellent option for businesses looking to save on air conditioning bills. EPDM also has excellent water resistance, making it a great choice for areas with heavy rainfall.
EPDM is also lightweight and easy to install, which can help lower labor costs. The material is flexible, which means it can easily expand and contract with changes in temperature without cracking. This helps it last longer than other materials that might become brittle over time.
Cons of Synthetic Rubber
While EPDM is durable, it is not completely invincible. The material can be punctured or torn if sharp objects, like tree branches or debris, fall on it.
It also has a limited range of colors, which might not be ideal if you want a specific look for your store’s roof. Additionally, some people find that EPDM can discolor or degrade when exposed to sunlight over time.
Another disadvantage of EPDM is that it requires regular maintenance. While it doesn’t need much care, occasional inspections are necessary to make sure there are no leaks or damage.
TPO (Thermoplastic Olefin)
TPO is a newer roofing material that has gained popularity in recent years. It is a single-ply membrane that is made from a blend of rubber and plastic.
TPO roofs are white or light-colored, which makes them highly reflective and energy efficient. This type of roof is known for its ability to resist UV rays and harsh weather.
Pros of TPO
One of the best features of TPO is its energy efficiency. TPO reflects sunlight, which helps keep your store cooler in hot weather and lowers energy costs.
This material is also resistant to UV rays, which can extend the life of your roof. The white color of TPO is ideal for reducing heat absorption, which helps improve the overall comfort of your building.
TPO is also known for being easy to install. The material comes in large sheets, which makes the installation process faster and less complicated. It is also more affordable than other low slope roofing materials, making it an attractive option for store owners on a budget.
Cons of TPO
One downside of TPO is that it is not as durable as some other materials. While it can last for 10 to 20 years, it may not last as long as BUR or EPDM. TPO can also be more prone to punctures and damage from hail or falling debris.
Additionally, TPO’s heat-welded seams are vulnerable to wear and tear over time, which can lead to leaks. TPO also requires more maintenance than some other options. Regular inspections are needed to check for issues, and repairs can be more expensive if the seams begin to fail. This means that while TPO is affordable upfront, the long-term maintenance costs can add up.
When deciding on the best low slope roofing materials for your store, consider the climate, your store’s budget, and how much maintenance you are willing to take on.
A commercial roof replacement contractor can help you make the right decision for your store’s roof by providing expert advice and recommendations based on your needs.
Low Slope Roofing Materials Are Worth It!
Choosing the right low slope roofing materials for your store is a big decision. Each option-whether it’s built-up roofing, synthetic rubber, or TPO-has its own set of advantages and disadvantages.
It’s important to consider your store’s specific needs, such as energy efficiency, durability, and maintenance requirements. By understanding the pros and cons of these materials, you can make an informed choice that will protect your store for years to come.
