The Cost of Replacing a Roof

Replacing a roof can be a homeowner’s nightmare. But there comes a time when even the sturdiest roof reaches the end of its life, at which point it can cost an arm and a leg to replace. The average homeowner spends around $6, 000 dollars to have a new roof installed. But not all roofs carry the same price tag. If it comes time to install a new roof there are several factors that will determine what you’ll pay in the end. The hit to your wallet will depend on the size of your roof, the material used, your location, the pitch of your roof, the cost of removing your old roof, and whether or not you have protruding structures like chimneys or skylights on your roof.

Roof Size

The size of your roof actually has the most influence on the how much you’ll spend to have it replaced. Why? Because roofing contractors actually charge per square foot of roofing installed. Contractors break down the surface area of your roof into roofing squares. One roofing square has a dimension of 10 x 10 foot, which is 100 square feet. The more roofing squares you have the more you’ll spend.

Pitch of the Roof

The pitch of your roof is simply the angle of its slope. It’s a measure of how high your roof rises over a 12-inch run. The pitch of a roof is given as a ratio, with the ratio of 6:12 being the average pitch a roof. A 6:12 pitch means that the roof rises 6 inches vertically for every 12 inches it runs horizontally. Steeper roofs will cost more to replace because it’s more difficult to do work on, takes more time (labor hours) to replace, and because the roofing company has to pay more in insurance costs due to the risk involved.

The Type of Material Used

There are a variety of roofing materials to choose from, from asphalt shingle, the most common roofing used in America, to slate roofing. But the price you pay for these materials and their installation will also vary. Higher end roofing like slate and tile are the priciest of the bunch. While the material for an asphalt shingle roof may cost $120-400 per 100 square foot, the material for a tile and slate roofs can easily cost anywhere between $600 to $4000 dollar per 100 square foot. But even though the material for slate and tile roofing are the most expensive to purchase, their durability is second to none. Tile, metal, and slate roofing may give upwards of 50 years use. You’ll also have to factor in the cost of materials like underlayment, ridge caps, and trimmings. The average roof will need two rolls of underlayment. With each roll of underlayment costing around $50, you’ll spend around $100 in underlayment costs.

Your location

The service fees your contractor charges will depend on the state you’re in. In states like Georgia, South Carolina, and Alabama the cost of replacing your roof will be less than the price you’d have to pay if you were in a state like New Jersey.

The Price of Removing Your Old Roof

Of course, your existing roof must be stripped away to make way for the new, and that’s not going to happen for free. What you pay for this service will depend on the size of your roof and the contractor you hire. But on average the price tag for this service sits around $1,000.

Protruding Features That Must be Worked Around

A lot of houses come with chimneys, skylights and other such adornments and protrusions that the roofer must work around when installing your roof. But this increases the work roofers must do, which also increases the price you’ll pay to have your roof changed.

In conclusion, there is no set price for replacing a roof. What you’ll pay will be determined by a number of factors that may be entirely out of your control. However, you’ll pay less to have an asphalt shingle roof installed than a tile roof if the same conditions apply.
