How Much Does Flat Roof Replacement Cost?

Flat roofing systems have a leveled structure that is easier to maintain than other roofing systems. They also have a beautiful appeal that can improve the look of your business. Flat roofs continue to dominate the commercial roofing industry, and over the years, flat roofs have become somewhat popular in residential properties as well.

However, like every other roofing system, flat roofs also have a certain lifespan, and you will need to replace them at some point in time. If you are also looking to replace your roof, then you should learn about the cost of flat roof replacement. This article will focus on just that! Below, we will discuss how much it will cost to replace a flat roof and some factors that affect the price of a flat roof replacement.

What Is The Average Cost Of Flat Roof Replacement?

Before we move to the core of this article, you should know that the cost of flat roof replacement services depends on various factors. For example, your neighbor’s price to replace his roof may be different from what you will have to pay. However, getting an idea of the total cost is always good so that you are well-informed and can negotiate with the roofing contractor accordingly.

The average cost of flat roof replacement in the United States is between $3,000 – $9,600. The national average is about $6000 (for a roof with an area of 1000 square feet). As we talked about earlier, this figure is a ballpark estimate, and factors such as the size of your roof and the materials you use will play a role in influencing the ultimate cost.

Types Of Flat Roofing Materials For Replacement (And Their Total Cost)

The cost of materials will depend on what type you choose for your flat roofing replacement. Certain types are more expensive than others, so it’s essential to do your research before you choose a roofing material. Some common types of flat roofing materials include the following options:

TPO

TPO stands for Thermoplastic Polyolefin and is a thermoplastic polymer used in various applications. It’s also used for roofing because it’s incredibly durable and can withstand high temperatures, and TPO does not become brittle in cold weather or crack when exposed to sunlight. It is a single-ply roofing membrane that is suitable for commercial properties.

The cost of TPO flat roof replacement is in the range of $3.5 to $9 per square foot. TPO is one of the most recent developments in the flat roof industry and can last for 20-30 years, depending on the location, maintenance, etc.

EPDM

EPDM is one of the most popular flat roof materials in North America. It has been around for years and it remains a strong choice for commercial properties. EPDM stands for Ethylene Propylene Diene Monomer, and it is also known as a rubber roof. It comes in rolls that the roofing contractor lays on your roof.

This synthetic rubber material has good resistance to weathering, UV rays, and ozone damage. It is also resistant to many different chemicals as well as water damage.

If you want to install an EPDM flat roof, it can cost you around $5-$13 per square foot. The cost is slightly more expensive than a TPO roof, but it offers a much longer lifespan, up to 50 years with proper maintenance.

Modified Bitumen

Modified bitumen is less popular than other single-ply roofing membranes such as TPO and EPDM, but it is still used by many business owners due to its cost and strength. Modified bitumen combines asphalt material (bitumen) with several additives and polymers. As a result, you get a modified roofing material or an enhanced version of basic asphalt that offers a better lifespan and durability. You also get flexibility when it comes to installation methods.

Since these are asphalt-based materials, the cost is relatively low compared to some other materials. Modified bitumen flat roof replacement costs around $4-$7 per square foot. However, the lifespan of the material is average.

Metal Roof

Metal roofs are one of the most popular roofing materials for both commercial and residential buildings, and metal roofs are another option if you want a flat roof for your home or business. They are usually made from steel or copper, but other options such as aluminum or zinc are also used sometimes. Metal roofs have many benefits over other types of flat roofs: they’re lightweight, durable (lasting up to 50 years), easy to install, and require little maintenance.

Since you can use a variety of metals for roofing, the price range is more comprehensive. The cost of a metal roof is in the range of $5-$30. With more expensive options, such as copper being more than 25$ per square foot

Other Factors Affecting Flat Roof Replacement Cost

The type of material is one of the biggest factors that can affect the price of replacing your roof, and it can even determine how long it will take to replace the roofing system. However, there are some other factors to consider, such as the following:

Size:

The larger your flat roof is, the more it will cost to replace. The reason for this is simple: a more prominent system will take more material and extra time to replace than a smaller roof. Also, the contractor will need more employees to complete the job. So naturally, it will cost more money. You can judge the size of the roof based on the square footage of your home/commercial building. One square of roofing material equals 100 square feet.

Flat Roof Sealant

Generally, you can apply a sealant or a roof coating to the existing flat roof material to add an extra layer of protection. These are available in various materials and colors. A roof sealant improves the overall appearance and makes the material waterproof. The cost of the sealant can vary. Depending on the size of the flat roof, sealing can cost you around $500-$1500 extra.

Labor Costs

Labor charges are one of the major factors that can affect the cost of flat roof replacement. Flat roofs, unlike pitched roofs, do not use shingles or tiles but instead are covered with a sheet that is usually available in the form of rolls. The cost of labor is typically between 30 and 40 percent of the overall project cost.

The overall cost depends on certain factors such as the following:

  • Size of the roof
  • The complexity of the roof
  • Quality of the labor required
  • Total time that will be needed to replace the roof

Ventilation Factors

Whether you have a home with a flat roof or own a commercial building, maintaining proper ventilation is important. Ventilation is the process of ensuring that air does not become too hot or too cold, and it’s essential for your property’s health. A roof vent can increase ventilation, and it can cost you around $300-$500.

Should You Replace Your Flat Roof Yourself?

Flat roofs are generally considered easier to install and replace than a pitched roofing system. Due to this feature, many property owners are tempted to replace the flat roof themselves without having the proper credentials to do the job.
