What goes into the average cost to replace a roof?

Getting a new roof is a big investment; knowing the average cost to replace a roof is important as you research the best roofing contractors. There’s no short answer on average roof cost; because there are many variables in the materials and labor involved. Here is a quick guide to help understand what goes into the cost of a total roof replacement.

The size of your roof matters.

The size of your roof is the biggest factor when it comes to cost. Generally, roofers charge per roofing square, which is 10×10 feet (100 square feet.) For example, if a roof is 2000 square feet, it will be broken down into 20 roofing squares. The larger the roof, the more expensive the job.

How complex is your roof?

If your roof is particularly high or hard to access, the job is going to cost more. Can trucks be pulled up close to the house? If not, that equals more labor for the contractors. The pitch of your roof also has a strong influence on the price. The steeper the pitch, the more safety concerns and equipment will be required for the roofers on the job, adding to the overall cost. A steeply pitched roof is also just more complicated to work on, so the cost will reflect that. If you have a number of different architectural angles and/or chimneys, the cost may be higher.

What type of materials are being used?

As with any contracting job, a key factor for cost will be the quality of materials used. Roofing materials vary widely in cost and appearance, and there’s something available for any homeowner’s budget.

“Highly rated roofing contractors tell us that asphalt is the most affordable roofing option, followed by wood, metal, tile and slate. Materials for a metal roof can cost upwards of $1,800 per 100 square feet. You can pay twice as much for a metal roof compared to asphalt shingles, and as much as five times more for slate.” –Angie’s List

Other factors in the average cost to replace a roof.

Replacing a roof is more expensive than overlaying an existing roof, but total replacement is highly recommended to protect the integrity of your home. Undiscovered water damage can also affect the cost, as can the presence of multiple chimneys, skylights, and other decorative accoutrements.
