If you’ve been looking for how much does it cost to replace a commercial roof, you’ve come to the right place. Keep on reading for our full breakdown of the factors that influence the commercial roof costs.

Commercial Roof Replacement Costs

Most commercial roof purchasers are interested in learning about the many kinds of commercial roofing systems available, the most cost-effective commercial roof, and which type is superior.

The most popular kinds of roofing systems and their typical prices are shown below.

Single-Ply Membrane

A single-ply membrane is made up of rubber and other synthetic materials that are ballasted or chemically attached to insulation to create a protective layer on a business roof.

One of the most popular roofing materials is a single-ply membrane. It is available in a variety of styles and patterns to suit your requirements.

EPDM costs between $3.50 and $7.50 per square foot for a 20,000 square foot Single-ply Membrane. TPO prices vary from $3.50 to $6.50, including materials and labor. This commercial roofing solution may last up to 30 years.

Insulation is chosen by the customer as well. The insulation factor is not included in a single-ply membrane, giving you the flexibility to choose your insulation.

Metal Roofing

Corrugated and galvanized steel is the most common metal roofing material, although aluminum and tin are also viable choices. Because of its low weight, it is simple to install over an existing roof and apply a coating to prevent rust, provide UV protection, and waterproofing.

The average price per square foot is between $5 and $10. The cost of a tin roof, on the other hand, varies depending on the metal panels you choose.

Metal roofing may endure up to 40 years if built correctly. The following are some of the advantages of a metal roofing system.

It can be resistant to wind and snow. Also, metal roofs are typically made of recyclable materials, making them energy efficient.

Shingle Roofing

Shingle roofing is the preferred material for most houses and residential structures, with steep-slope commercial roofing having restricted applicability.

Metal, slate, ceramic, wood, plastic, and composite materials like asphalt are all used to make shingles.

The materials and labor expenses for installing this kind of business roof range from $2.50 to $5 per square foot on average. The style of shingle roofing you choose has a major effect on your roof’s total cost.

Built-Up Roofing

“Tar and gravel” roofs are another name for built-up roofs. In order to create a layer, asphalt and specified textiles are alternated onto the roof. The last layer of a built-up roof is made up of stone and gravel.

A commercial built-up roof typically costs between $5.50 and $8.50 per square foot in materials and labor. The cost is determined by the material you choose.

If correctly constructed and maintained, a built-up roofing system may last up to 40 years. It has a number of advantages, including protection from UV rays.

The continuous solid surface eliminates susceptible leakage regions by eliminating joints and seams. Also, after installation, upkeep is minimal.

What Factors Affect Commercial Roof Prices?

The price of a commercial roof is influenced by a number of variables, some of which are mentioned here.

And, those can be applied to your commercial roof regardless of its type.

Roof Damage

Repairing what’s beneath your roof and protecting your property from moisture may have hidden expenses, depending on the roofing type and insulation used.

Uncovering what is under your current roof may be costly, and the expenses can rapidly mount if any problems are discovered.

Roof Size

For obvious reasons, a bigger roof requires more money to repair.

Even so, the price per square foot may go down if you choose a lower-priced material or a different roof design.

Roof Structures

Due to the fact that installers have to work around existing buildings, the more you have on your roof, the more you’ll pay for installation.

This covers things like ventilation and drainage.

Permissions and Regulations

If you need specific permission to build your roof, it will take longer and cost more money.

Also, bear in mind any local building regulations that may apply to your new roof.

Additional Factors to Consider

Commercial roofs may need upgrades to the drainage slopes, insulation, or parapet walls from time to time.

Additional expenses may be given by your roofing contractor and should be carefully examined since a roof, regardless of the materials, cannot operate effectively without a complete system that works together to protect your building.


Another consideration when designing a new roofing system is the potential long-term maintenance requirements of the roof.

You have the option of signing a contract for roof care or just restoring the roof system on a regular basis. Don’t forget about those additional expenses. In the long run, this will save you money since it extends the life of your roofing system.

Restoration Coating using Silicone

Instead of re-roofing, try using Silicone Restoration Coating, which costs between $2 and $5 per square foot.

After the old roofing has been cleaned and dried, the contractor will apply a silicone coating over it. It fixes all the problems with the roof’s existing top layer by restoring it.
