Average Cost of Flat Roof Replacement in 2022

With costs increasing across industries, you might be too nervous to check on the current flat roof replacement cost – even if you need to complete the project on your commercial building. Unfortunately, you’re right to be worried.

The roofing industry has been affected by inflation, supply chain issues, and labor shortages, and these problems are reflected in the increased price of flat roof installation. We’ll break down the average cost to replace a flat roof and give you an alternative solution.

How Much Does Flat Roof Replacement Cost?

Flat roof replacement costs between $4 to $13 per square foot.

Factors to Consider When Replacing a Flat Roof

We know this considerable range (from $4 to $13 per square foot) could make a difference of tens of thousands of dollars. So, here are some of the factors that go into replacement costs.

Replacing Flat Roof Materials

The type of commercial flat roofing material used on your replacement projects can make a difference in the project’s final cost.

For example, ethylene propylene diene monomer (EPDM), a roofing material made from oil and natural gas byproducts, can cost as much as $13 per square foot. However, modified bitumen, which is rolled out onto the flat roof and secured with a blowtorch, may only cost $4 per square foot. Metal roofing tends to be the most expensive.

When it’s time for a flat roof replacement, consider the price of the roof materials and ensure you have a solid understanding of the roof’s lifespan for each type of roofing material. Some commercial flat roofs are only lasting 15 to 20 years – depending on your climate and dedication to completing maintenance tasks.

Number of Roof Penetrations

The more hatches, skylights, chimneys, and exhaust pipes there are on commercial buildings, the more complicated it will be to complete a roof replacement. Penetrations require special flashing work, which will increase both the labor and material costs.

Roof Removal Costs

Depending on the type of roof membrane and condition, you may have to pay for old roof removal costs and dump fees. In addition, tearing off your existing roof has environmental ramifications, as the old material has to go somewhere.

On a side note, you will probably not be able to conduct business as usual while installing your new flat roof. However, most roof replacement calculators don’t factor in the costs associated with disrupting your business.

Roof Size and Complexity of the Job

The size of the building plays a significant factor in the total costs for flat roof membranes. However, roofing contractors will also charge more for a project for a building in a congested or hard-to-get-to area. Flat roofing projects are tricky to complete in metropolitan areas – especially if the original flat roofing material needs to be removed.

As you read this, you might be doing a quick calculation to determine how much your flat roof costs to replace.
