How much does a flat roof replacement cost?

Flat Roof Replacement Costs To Consider

You have to make sure you’re thinking of all the main roof replacement components when tackling a project like flat roof replacement. Some key cost factors to keep in mind are listed below!

Material Costs

There is no doubt that roofing materials themselves are diverse, made of different substances, have a variety of textures and of course have their pros and cons. Depending on what kind of material to roof your home with can greatly impact not only the cost, but the longevity and curb appeal of your home!

Labor Costs

A professional installation is key when dealing with a flat roof. Going with someone less experienced may save you money in the beginning, but when your flat roof ends up with ponding, you’ll be paying much more in the long run! Labor costs can vary on a few variables:

Home Size and Roof Complexity – Larger roofs or those with complex designs (like a layered flat roof) require more labor, planning, and even material. All of these things can lead to an increase in costs.
Roofing Contractor Experience – You want a roofer with receipts! A roofer with references and proof of work! A roofer with decades of experience is going to know how to make roofs last longer so choose expertise!

Regional Labor Rates – Depending on where you live, there can be differences in cost due to the region’s cost of living and local market conditions.

Removal and Disposal

Removing the old roofing materials may be something that people tend to forget when considering a roofing project, but it certainly does contribute to the total cost at the completion of a project.

Permit and Inspections

If you are looking to have a flat roof replaced, expect to get a building permit and go through some inspections to satisfy local building regulations. Likewise, costs for permits and fees for inspections are circumstantial, the project’s location and size being the two factors that stand out.

Roofing permit fees tend to cost anywhere in the region of $100 to $500, while inspection fees, if applicable, are often charged separately. These average between $50 and $150 per inspection.

Flat Roof Replacement Cost By Roof Material Type

Depending on the type of material, your overall roofing estimate can vary greatly. Here are some of the most popular flat roof materials you can choose from.

Flat Rubber or EPDM

Rubber roofing, also known as EPDM (ethylene propylene diene terpolymer), can often range from $4-$8 dollars per square foot.

It is widely recognized for its durability and high resistance to UV exposure and weathering which makes it ideal for use in flat roof homes situated in hot locations.

Modified Bitumen

Coming in at around $3 – $6 dollars per square foot, modified bitumen roofing consists of several layers of asphalt and reinforcing fabrics.

It’s designed with flexibility in mind and offers a more granular surface to resist weather better.

Fiberglass / GRP

Fiberglass (or glass reinforced plastic) is a strong, lightweight material that offers top waterproofing options at $3 – $5 per square foot.

Due to its resistance to environmental factors, it’s an excellent option for homes that endure a lot of annual rain or lots of direct sunlight!

Built-up Felt Roofing

Built-up felt roofing involves multiple layers of bitumen and reinforcing fabrics to make it durable and offer great protection from the elements.

It is known as one of the more cost effective choices, coming in at $3 – $5 per square foot, but it is well known for its durability!

Standing Seam Metal Roofing

Arguably the most expensive option, a standing seam metal roof can set you back around $8 – $12 dollars per square foot. What does the hike in price get you?

Exceptional durability and longevity along with a sleek and modern look. Metal roofing can come in dozens of colors from polished metals to special weather resistant paints.
