Flat roofs are commonly seen on commercial buildings because they can support heavy equipment and allow repair teams to walk on them easily. They are strong, cost-effective, and provide protection to the building. However, while they are durable, they don’t last forever and don’t need the same kind of shingles or frequent repairs that residential roofs require.
If you want to figure out how much it will cost to replace a flat roof, you need to measure its size in squares, which equals 100 square feet. Generally, the bigger the roof, the higher the cost, though the type of materials and additional features can also affect the final price. For flat roofs, the cost typically ranges from $2.50 to $9 per square foot, which translates to $250 to $900 per roofing square. Flat roofs are usually smaller than the sloped roofs you see on houses.
When considering the cost of replacing your flat roof, keep in mind several factors, including:
Materials: You can choose from materials like modified bitumen, spray foam, or thermoplastic polyolefin (TPO).
Removal and Disposal: Removing the old roof and disposing of it will add to the expenses.
Repairs: If there are any issues with the building structure, these will also need to be addressed during the replacement.
Labor: The cost of the labor required for the installation.
To get an accurate estimate, it’s a good idea to contact a roofing company for a free quote that considers all these factors. Keep in mind that the cost of replacing a flat roof can vary from property to property.
Now, let’s briefly look at the materials commonly used for flat commercial roofs:
Spray Foam
This involves spraying a thick layer of polyurethane foam, which dries into a lightweight, weather-resistant membrane. It provides insulation and can reduce cooling costs.
Modified Bitumen
This is a strong asphalt roofing membrane that can be installed in multiple layers. While it’s more expensive than some alternatives, it’s known for its durability and can last for 20 years or more, even in hot climates like Florida. It can also self-heal small punctures because of the rubber and solvents in the asphalt mix.
Choosing the right material for your flat roof replacement depends on your specific needs and budget. Each of these materials has its own advantages and costs.
