Consider The Area Of The Roof

One of the first things roofing contractors need to do when they’re estimating the cost of a project is to figure out the area of the roof. To estimate a roofing job, it is vital to calculate the area beforehand, because the larger the area, the more material and labor will be needed, and the higher the cost.

The most common method is to simply measure the length and width of the roof and multiply those numbers together. However, this can be tricky if the roof is irregular in shape. In that case, it’s often best to break the roof up into smaller sections and measure each one separately.

Once you have the area of the roof, you can then begin to calculate the number of materials you’ll need and estimate the labor costs. With a little bit of planning, you can be sure to get an accurate estimate for your next roofing project.

Factor In The Material Cost

When estimating the cost of a roofing project, it’s important to factor in the cost of materials. The type of roofing material you choose will have a big impact on the overall cost of the project. For example, asphalt shingles are one of the most affordable options, while metal roofing is more expensive.

Between shingles, underlayment, flashing, and other necessary supplies, material costs can add up quickly. That’s why it’s important to factor in the cost of materials when estimating the roofing cost of a project. By taking into account all of the potential expenses, you can ensure that your estimate is as accurate as possible. And that’s good news for both you and your clients.

Don’t forget the overhead cost

When you’re estimating the roofing cost of a project, there are a few overhead costs to consider like transport, taxes, equipment rental, etc. First, you’ll need to consider the amount you will be paying to each subcontractor for sourcing the necessary material and equipment.

Next, you’ll need to account for the cost of labor. This will include the wage rate, payroll taxes, insurance, and benefits of workers you might hire, as well as the cost of any equipment you need to rent.

Finally, you’ll need to factor in the cost of permits and insurance. These costs can vary depending on your location, but they’re important to consider nonetheless. By keeping all of these costs in mind, you can be sure that your estimate is as accurate as possible.

Add your markup for desired profits

As a contractor, one of the most important things you can do is to make sure that you add your markup for desired profit into the roofing cost estimate of a project. This will ensure that you are making a profit on the job and that you are not simply breaking even or losing money.

There are a few different ways to calculate your markup, but a common method is to multiply the total cost of the project by 1.5. This will give you a 50% markup, which should be enough to cover your costs and make a healthy profit.

You will also need to adjust your markup depending on the specific project and your own business expenses. But if you keep this simple rule in mind, you will be well on your way to estimating roofing costs like a pro!


You can get a good idea of what the job will cost by considering the size of the house, the pitch of the roof, and local labor and material costs. With that information in hand, you can put together a competitive bid that gives your customer great value without sacrificing your bottom line.
