Replacing a roof requires a number of questions to be answered. Will you hire a professional to do the job or will you instead do it yourself? In either case, you might want to use a roof replacement calculator to get an idea of how much the materials will cost which may help you negotiate a good price from a professional. It can also protect you from some “professionals” from trying to pad their bill as well. There are several steps that you will take when using the calculator.

Measuring Your Roof

The first step will be to determine the size of the roof that you are replacing. The cost of the materials will be determined by how large your roof surface actually is. Keep in mind that there are some variations that can decrease the actual amount of materials that are needed such as skylights and other obstacles on the roof that must be cut around. Once you have the measurements you will enter them into the roof calculator as Length X Width.

Note: it is recommended that you do these measurements on the ground, measuring the building’s outside dimensions.

Second Step: What is the Pitch of Your Roof?

Your roof’s pitch refers to how much of a slope or angle it has. Some are very steep while others are virtually flat. The roof calculator will typically have a drop down menu which will show you the various options. These can include:

  • Flat
  • Low
  • Medium
  • Steep
  • Very steep
  • Mansard- a specialized roof type which is sloped on all four sides. It has a steep slope as well as a lesser slope.

Of these, the very steep and the Mansard roof are typically best left to professionals for safety reasons.

Third Step: Choose the Material for Your Roof

In addition to the slope of your roof, you will need to choose the type of material that you are interested in using. There are a number of different choices that you can consider including asphalt, steel or other metals and clay tiles. Remember that you must know the benefits and drawbacks of each type of material that you are using. You should also consider whether they are right for your roof.

Fourth Step: Your Current Roof

Next, the calculator will ask whether you are going to tear off the current roof. This step is recommended if you have issues with the roof such as rotting or missing materials or serious leaks. Some building codes also do not allow for more than a single layer of roofing so it might be required. In addition to the cost of removing your roof, you should also consider the cost of disposal of the used materials once they are removed. This is typically not an expense covered by the roofing calculator.
