Replacing your roof is a big decision that can significantly impact your home’s value. Not only does your roof affect your home’s curb appeal, but it’s also a major factor in protecting your home from the elements. The price of a new roof can vary greatly, and you may be wondering what exactly goes into the cost of a roof replacement. Learn more about the different roof pricing factors so you can be better informed when you’re ready to get an estimate from a reputable roof contractor.

Roof Size

The size of your roof is one of the most significant factors that will affect the price of your roof replacement. Larger roofs use more materials and labor to replace, so they will be more expensive. You may hear roofing companies talk about a “roofing square” when determining your roof’s size. This is simply a measurement that is equal to 100 square feet. So, if your roof is 2,000 square feet, then it would be considered 20 roofing squares.

Roof Pitch or Slope

Roofs with a higher pitch (or level of steepness) are more challenging to work on and require special safety equipment, so they will be more expensive to replace. In contrast, a roof with a low pitch is easier to work on and will likely be less expensive (depending on the other factors discussed in this article).

Roofing Materials

The type of roofing material you choose will also affect the price. Asphalt shingles are the most common and typically the most affordable type of roofing material, but there are a range of options to choose from, including cedar shake, copper, slate, and more. And each material generally has different grades or levels of quality too. Higher-quality materials will obviously cost more, but they will also last longer and often include more comprehensive warranties. Your chosen roofing material will also affect the lifespan of your roof and the level of protection it provides, so be sure to discuss your options with a professional before making a decision.

Roof Complexity & Features

The architectural design of your roof plays a significant role in the cost of replacing it as well. If your roof has a lot of different angles, gables, valleys, or other features, it will likely be more expensive to replace than a less complex roof. This is because more complex roofs take more time and labor to replace, and they often require unique materials or additional overlapping. And other features like chimneys, vents, and skylights will also need to be considered and factored into the price because they will require additional caulking and flashing to prevent leaks.

Roofing System

Depending on the condition of your current roof, you may have some damage to the underlying roofing system. This includes the underlayment, decking, ventilation, and other structural components. If your roofing system is in good condition, you may simply be able to install new shingles or other materials over the top. However, if your roofing system is damaged, it will need to be repaired or replaced before new materials can be installed.


If your roof is easy to access and replace, it will likely be less expensive than a roof that is more difficult to reach. This is because roofs that are difficult to access often require special equipment or scaffolding, which can add to the cost. So, a second-story roof or a roof surrounded by trees may cost more to replace than a single-story roof with no obstacles.

Location & Permits

The location of your home can also affect the price of your roof replacement. If you live in an area prone to hurricanes, severe weather, or other natural disasters, your roofing materials and installation will need to withstand these conditions. So, you may need to invest in more expensive materials, which will cost more. Additionally, different localities have varying prices for building permits, so if you live in an area with high permit prices, this will increase the cost of your roof replacement.

Removal & Tear Down Costs

The price of your roof replacement will also include the cost of removing and disposing of your old roof. The disposal price is generally included in the installation price, but it is worth mentioning as it can add to the overall cost. And depending on where you live, the waste disposal and landfill fees may vary.


Finally, the price of your roof replacement may also be affected by the types of warranties and guarantees offered. Higher-quality materials and installation often come with better warranties that will last longer and provide more coverage. Be sure to ask about the warranties offered by the roofing contractor you are considering to an idea of what they include and cover.
