We’ve updated this article in December 2020, and also added a roof replacement cost calculator.
The fact is, roofs don’t really have price tags dangling off of them. So, how do you know how much a new roof costs? There are quite a few factors to consider. As Middle Tennessee’s leading Roofing company, we’ve got answers that can help you budget your roof replacement.
First, it helps to understand the various parts that make up your whole roof.
Understanding your roof system
A roof is made up of several layers that work together as a system to protect your home. Proper installation of each component protects the roof, attic, walls, and foundation from wind, rain, ice, heat, and humidity.
In addition to shingles, a complete roofing system includes:
- Deck: The main wooden structure.
- Underlayment: A layer installed under the shingles to keep the deck dry.
- Flashing: Material used to deflect water away from seams or joints around chimneys, exhausts, etc.
- Vents: Items that optimize airflow through the attic to keep the roof dry.
- Drip edge: Material along the edge of the roof that guides water to the ground or in the gutters.
- Soffit: The area underneath a roof overhang.
- Fascia: The horizontal roof trim on the end of the rafters that often holds the gutters.
- Winterguard: waterproofing shingle underlayment – key in fighting water penetration
Factors that affect new roof costs
Now that you understand the complexity and interconnectedness of your roof replacement, here are five factors that will impact the cost:
The biggest factor in determining how much it will cost to replace your roof is the size of your roof. The cost of roof replacement is calculated in terms of roofing squares; one roofing square is 10 feet by 10 feet, or 100 square feet. Whenever possible, we use state-of-the-art, satellite technology to precisely measure the roof of your home. This ensures the right amount of roofing materials are ordered—thereby saving costs and reducing waste—and helps provide a better estimate on how long the project will take.
Before a new roof can be installed, your roofing professional will need to remove and dispose of the old roof, which can include layers of old shingles and underlayment. Any debris must be moved to a proper landfill site, which typically charges by the weight of the materials. The costs associated with this process depend on the amount of time and labor it takes to remove the old materials, as well as the landfill charges.
Style & Shape
The slope of a roof can make a big difference in determining the cost of replacement. The slope is the angle of incline and indicates the vertical rise compared to the horizontal run. For example, if your roof’s slope is 6:12, it means the roof rises six inches vertically for every 12 inches it runs horizontally. The steeper the slope of the roof, the more shingles it takes to cover it. In addition, a roof with a very steep slope requires greater staging and safety equipment, which can cost more.
There can be a major cost difference between the different types of roofing materials. Asphalt is generally the most affordable option, with slate and shake, or wood shingles being the most labor-intensive and the most expensive. Five Points Roofing has a whole range of shingle options, including luxury and designer asphalt shingles.
Chimneys, skylights and vents can improve the look of your roof but for a roofing contractor, these features can all be potential obstacles to carefully work around during the installation process.
