What Makes Up the Cost of a New Roof?

The average roof needs to be replaced every 15-20 years. That means, inevitably, you’re going to have to invest in at least one new roof during your time as a homeowner. Replacing a roof is a big investment for most homeowners, so it makes sense to know where your money goes. Understanding the cost composition of a new roof can help owners make informed decisions about which aspects of a new roof they can’t afford to pass on and which are must-haves.

Roof Size
Size influences the cost of a new roof more than any other factor. Roofing companies charge per roofing square. One roofing square is equal to a 10-by-10-foot area or 100 square feet.
   
Pitch
The pitch or slope of the roof is also a cost factor. The higher the pitch, the more materials it will require. Roof systems with a ratio of about 7:12 or above (height vs. length) may not be walkable and require additional safety supplies.
Type of Application
The overall cost of a new roof depends on how installed on the roof deck. Built-up roofs and other low-slope roofs need a layer of weatherproofing, reinforcement and surfacing. Steep-slope roofs are also made up of multiple components, such as the roof deck itself, underlayment and the final roof covering. Flashing and gutters may also need to be replaced – all of these factors and more affect the overall price of the project.
Materials Used
Cost of a new roof varies greatly depending on the type of system used. The most common roof types are asphalt, slate, tile and metal. Asphalt is usually the most affordable - the average lifespan is 20 years. Tile, slate and metal are costlier, but may last up to 50 years.
Number of Layers
Removing old shingles is a quick way to drive up the cost of a roof replacement. While removing old shingles, most roofing contractors also look for existing damage. Any existing damage should be repaired before the new roof system is installed or it may fail prematurely.
Skylights, Chimneys and Other Features
Skylights, chimneys, vents, plumbing pipes and other features must be taken into account when replacing a roof system. Each adornment must be addressed and, if necessary, repaired. These features should also be inspected after major storms to prevent minor damage from becoming a major problem.
