Figuring Out the Cost to Roof a House

January 11, 2019

The cost to roof a house can be a daunting number, especially if you weren’t expecting the need for a roof replacement or repair. The process to getting a roof replacement only gets more confusing when multiple contractors are giving different estimates. Even a quick Google search results in a wide range of pricing from $2,000 to $15,000.

The truth is, the cost to roof a house can vary greatly depending on a few different factors. Understanding what roofing contractors consider when they give an estimate can be very helpful when you’re trying to calculate the cost of a roof.

Removal and Disposal

Roofing is an investment that is best done right the first time. Layering another roof on top of your existing one may seem like a good way to minimize costs, but most building codes allow two layers of roofing. If your old roof is in bad shape, leaking, or can’t support the weight of a new roof on top of it, then it’s best to remove it to avoid unexpected problems in the future. In addition to the time and labor it takes to remove a roof, contractors will also need to consider disposal and landfill charges.

Roof Size and Shape

Size is the biggest contributing factor when it comes to roofing costs. A reliable contractor will come and measure the roof of your house in order to give the best estimate. The shape and slope are also critical factors in an estimation. Roofs that are considerably sloped will require more shingles and extra safety measures will need to be taken to do the install. Flat or low sloped roofs will also require a little extra care and attention, especially if you live in an area with a rainy climate.

Materials

Now that you know the size of your roof, it’s time to consider the materials. There are a variety of roofing materials out there. Basic 3-tab asphalt shingles will be the least expensive and can last up to 25 years. There are also architectural and premium asphalt shingles. They are thicker than 3-tab shingles and last longer, but cost more depending on the manufacturer. Nowadays, metal roofs are also growing in popularity, coming in different styles and colors. They are energy efficient and can last up to 50 years.

Other Factors

Safety equipment, time, and labor are all other factors in the cost to roof a house. If you undergoing a replacement because you experienced roofing problems, it’s possible your contractor could find more damage after removing your existing roof. Storm damage and wood rot are often unexpected damages that add to roofing costs. Extra roofing features like skylights, chimneys, and vents will also add to roofing costs.
