Factors That May Affect Your Commercial Roof Replacement Costs

Not many people may know of this, but there are actually many factors that may affect the overall total of your commercial roof replacement costs. That said, if you do not want to be caught off guard with the price, you must familiarize yourself with the following cost-altering pointers so that you would be able to compute your expenses even before being handed the replacement fee.

1. The Roofing Material to Be Used

Roofing materials have come a long way and have been improved over the years. That said, the different materials come with varying costs, so be sure to get the one that is most practical for your business. To help you narrow down your choices, you may want to consider the following:

Asphalt shingles cost around $4 per square foot, making them the cheapest materials. Metal roofing is made from steel, aluminum, or copper and cost around $6 per square foot.

Organic shingles are made from roofing materials like wood and cost between $6 and $10 per square foot. Clay roofing tiles are made from a natural material, clays, and cost around $7 per square foot. Slate tiles are made from natural rock and cost around $10 per square foot.

2. The Roofing Contractor or Company

There are many contractors or companies who offer commercial roofing services, but with products of varying quality, it is best to take your time and find one that can provide you with the best service in the industry. To get a fair price and good quality, here are some pointers to consider:

Choose only a qualified and licensed contractor. Make sure to obtain the necessary permits and clearances. Negotiate for your desired price.

3. The Size of the Commercial Building

Of course, the size of the commercial building should be one of the factors to consider for the roof replacement costs. It is no secret that the larger the building, the more the material will cost. That said, roofs are usually priced per square foot. To give you an idea, the following macro pricing is what you can expect:

For a small commercial building with a flat roof and less than 2,500 square feet, expect to pay around $100 per square foot or $25,000. For a medium-sized building with a flat roof and 2,500 to 5,000 square feet, expect to pay around $120 per square foot or $30,000.

For a large commercial building with a flat roof and 5,000 to 10,000 square feet, expect to pay around $140 per square foot or $40,000.

Take note that the prices above may still vary, depending on the contractor, so be sure to ask for the actual fee.

4. The Insulation to Be Used underneath the Roof

It is common for roofing contractors to install at least one layer of plywood sheets on the roof deck before the roofing matter is applied. Depending on your needs and your budget, you may want to ask the contractor to use a better insulation board material, such as phenolic or fiberglass.

These materials are specially designed to protect the building from cold and heat. Some of the insulation boards may cost a bit more, but they can save you a lot of money in the long run.


As you can see, there are many factors that may affect your total commercial roof replacement costs. Remember to consider them and never hesitate to ask for the price before signing the contract for replacement. And when it comes to the materials, do your homework and only choose from trusted, quality brands.
