Learn how roofing costs are estimated


The roof is one of the biggest investments you’ll make in your home. Find out how the costs of installation of a new roof and repairs on existing roofs are determined.


Size: Roofers will calculate the exact size and dimensions of your roof to best estimate the amount of materials needed.


Slope of your roof: The steeper your roof is, the more materials will be needed to cover it.


Materials: The price for materials will depend on what kind of roofing materials you choose to have installed.


Roof access: If your roof is difficult to access, or if it is multiple stories, contractors may charge more.


Difficulty level: If your project is complex – for example, if you have chimneys, skylights and vents that roofers need to work around – the higher the cost could be.


Location: Where you live could determine your estimate.
