Factors to Consider When Replacing a Flat Top Roof

The cost per square foot of replacing a commercial roof depends on a number of things.  First, there is the overall cost of the material used.  This cost can vary from a few dollars per square foot for tar and gravel roof material and modified bitumen all the way up to close to $12.00 per square foot for some metal or specialized membrane roofing.  Another thing to consider when budgeting for roof replacement is the overall cost of the labor needed to install the new roof.  While there are some viable DIY options available on the market today, most qualified professionals and inspectors recommend that you use professional roofers.  Simply put, replacing a commercial roof, or any roof for that matter is serious work, and making a mistake can have serious consequences.  A poorly installed membrane roof, for example could lead to water and moisture infiltration, which can result in things such as mold, foundational damage, and damage to the interior of your building.  And if you decide to replace your roof using modified bitumen, depending on the application process used, fire can certainly damage your building beyond repair.  Another factor to consider is when the roof is to be installed.  As you can imagine, weather and the amount of available daylight do play important rolls in how easily a new roof is installed.

The Cost of Materials

The cost of materials is probably the first thing that most people think about when budgeting for a new roof.  While prices have certainly become more reasonable in the last few years, it is still a major consideration when it comes to replacing a roof.  The overall cost per square foot of material depends on a number of factors, including how easily the material can be produced, the resources needed to make it, the amount of labor needed to produce the material, and the market value of the raw materials needed.  As you can imagine, the overall cost of materials per square foot can vary quite a bit.  For example, metal in the Boston area can range in price between $1.50 and a whooping $16.00 per square foot simply because of the availability of the metal, and the overall market price.  On the other hand, membrane material, such as EPDM, or PVC roofing material may be a bit on the expensive side, but the pricing is a bit more consistent overall.  In most cases, these materials range between $3.00 and $11.00 for the material.  On the less expensive end of the spectrum, materials for the tar and gravel method of roof replacement or using a modified bitumen usually cost about $1.00 to $2.00 per square foot.

The Cost of Labor

Once you’ve figured out how much the materials will cost you per square foot, you’ll need to consider the cost of the labor needed to replace the flat roof on your business.  Replacing a roof isn’t always a simple matter.  It often includes tearing off the old roof, inspecting the underlying roofing deck and materials for damage and signs of deterioration, replacing what is needed to ensure a safe and solid roof, replacing any insulation, and then finally replacing the actual roofing material.  If any of the steps needed are missed or done incorrectly, their can be some serious long term consequences such as foundational damage, water infiltration, or even mold growth.  This process is one of the most common reasons why it’s recommended to use a professional roofing company.  They simply have the training, expertise, and experience to do the job right the first time. 

Generally speaking labor for putting a replacement roof on a building is charged by the hour, at a rate of between $50 to $80 depending on the complexity and size of the job.  If you want to figure out the cost of labor per square foot, in most cases it’s safe to assume that labor will add between $1.00 and $3.00. 

The Cost of the Season

As you can imagine, the weather in the south Boston area can certainly play a part in the overall cost of replacing a roof.  Factors such as wind, cold temperatures, precipitation, and even excessive heat can make working with some materials more difficult, or even a bit more dangerous.  This is one of the reasons why most people choose to have their roofs replaced in the summer or early spring to help mitigate the added cost of mother nature.  However, doing a roofing project in the busy season for roofing companies also has a downside.  Since these companies are often quite busy, the overall costs may increase simply due to the availability of the labor.  In some cases, scheduling your roofing project for early autumn may be a more cost effective time overall.

When it comes to replacing the roof on your business, it’s not always just about the quality of the material used.  There are a number of hidden factors that can significantly change the cost of replacing your roof in the Boston area.
