Whether you are dealing with persistent leaks, an old roof, or you just want to upgrade, understanding the costs involved can help you plan your budget and make informed decisions.
Understanding Flat Roofs
Before we talk numbers, let’s quickly go over what a flat roof is. Contrary to its name, a flat roof isn’t entirely level. It has a slight slope (usually between 1/4 and 1/2-inch per foot) to allow for proper drainage. Flat roofs are commonly found on commercial buildings, apartment complexes, and some homes.
Components Involved In Replacing A Flat Roof
Installing or replacing your flat roof is a complex process and hence can be expensive. Other than the main roofing material, there are several components involved in a flat roof replacement. These include:
- Roofing Material
- Roofing Underlayment
- Roof Insulation
- Drainage System
- Old Roof Removal
How Much Does The Average Flat Roof Replacement Cost?
Now, let’s crunch some numbers. You can expect to pay between $3,000 and $10,000 for a flat roofing replacement in 2024. But, keep in mind that these are just rough estimates. The actual cost can vary depending on the specific condition of your roof, location, and more.
Factors Affecting Flat Roof Replacement Costs In Wisconsin
Now, let’s get to the part that you are here for. To break down flat roofing costs, we need to talk about the factors involved. These will determine how much you’ll need to shell out for replacing your flat roofing system in Wisconsin.
Roof Size
The larger the roof, the higher the cost. It’s as simple as that. Like pitched roofing systems, flat roofs are also measured in squares, where one square equals 100 square feet. So, if you have a 2,000-square foot roof, that’s 20 squares.
The cost can also be further influenced by the complexity of the roofing system. For example, the cost might be more if there are protrusions or several elements such as HVAC systems on your roof.
Here is a breakdown of the cost depending on the size of your roof:
| Size (in square feet) | Cost |
| 1,200 | $4,800–$15,600 |
| 1,500 | $6,000–$19,500 |
| 1,800 | $7,000–$23,400 |
| 2,000 | $8,000–$26,000 |
| 2,500 | $10,000–$32,500 |
Roofing Material
When considering flat roof replacement costs in 2024, the type of roofing material you select plays a pivotal role. Here are five popular options and their estimated costs per square foot:
Thermoplastic Polyolefin (TPO):
TPO is a newer roofing material known for its durability and environmental friendliness. It typically costs between $4 and $14 per square foot. TPO is a popular choice for its energy efficiency and ease of installation, however, in terms of price, it is a little more expensive than its flat roof counterparts such as EPDM.
Ethylene Propylene Diene Monomer (EPDM):
EPDM is a synthetic rubber membrane that is highly durable and cost-effective. It’s a popular choice for flat roofs and typically costs between $4 and $12 per square foot. EPDM is known for its resistance to UV rays and weather damage.
Modified Bitumen:
Modified bitumen is an asphalt-based roofing material that comes in roll or cap sheet form. It’s known for its durability and flexibility, making it a popular choice for flat roofs. Modified bitumen can range from $4 to $8 per square foot. It’s a good option for areas with extreme weather conditions.
PVC Roof:
PVC roofing membranes are known for their longevity and durability. It offers excellent resistance to chemicals, oil, and fire, making it a popular choice for commercial buildings. PVC typically costs between $4 and $7 per square foot.
Green Roof:
A green roof is very different from the other roofs that we have talked about, as it is not even a roofing material. This is a new age, energy efficient roofing option that is also known as a living roof. It is a roof covered with vegetation planted over a waterproofing membrane. While the initial cost of installing a green roof can be higher, ranging from $10 to $25 per square foot, it offers numerous environmental benefits, including improved insulation, reduced stormwater runoff, and extended roof life.
Roof Accessibility
If your roof is difficult to access, you can expect to pay more for labor. Factors like the building’s height, the presence of obstacles (like skylights or HVAC units), and the slope of the roof can all increase labor costs.
Roof Preparation
Before a new roof can be installed, the existing one needs to be removed, and the surface prepared. This process can involve tearing off the old roofing material, repairing any damaged decking, and applying a new vapor barrier or insulation. The more extensive the preparation, the higher the overall cost.
Labor Costs
Labor costs can vary significantly based on your location and the expertise of the roofing crew. In general, you can expect to pay anywhere from $1.50 to $4 per square foot for labor alone.
When it comes to labor costs for roofing projects, it’s important to keep in mind that the rates can vary based on a few factors. For instance, the location of the property can play a role in determining the labor costs, as rates may differ depending on the state or city where the work is being done. Additionally, the expertise of the roofing crew can also impact labor costs, as more skilled professionals may charge higher rates.
Conclusion
Replacing a flat roof is no small feat, and the costs can quickly add up. However, by understanding the different factors at play, you can make an informed decision and budget accordingly. Remember, investing in a high-quality flat roof replacement is crucial for protecting your home or business from water damage and maintaining energy efficiency.
