new roofAlthough replacing your roof might seem simple, there are many factors that affect its cost. The roof replacement cost includes more than just the shingles. Additional items such as nails, flashing, ventilation and labor also play a role in the overall cost. We will help you understand the average cost of replacing a roof. This article will help you understand what you need to protect your new roof and your home.

What is the Cost of a New Roof?

There are many factors that can affect the cost of replacing a roof. The average roof replacement cost is from $5,100 to $10,000. But, roof replacements can range between $1,200 and $30,000. Many roofing companies charge $3.50 to $5.00/sq. foot. A standard roof is about 1,700 square feet. Cost depends on many factors, including the square footage of your roof, its material and the existing damage.

You’ll get a roof made from lower-quality materials and work that is less expensive. But you have to face the consequences. You could end up having to have your roof replaced sooner if you choose to go with lower quality work. This could also void your warranty.

Before hiring a roofing company, make sure to ask about their liability and insurance to ensure you are protected in the event of an accident.

Let’s first explain how roofers measure material before we get into the details about the cost of materials. Roofers talk about the material’s cost in “squares”, which is a 10 by 10 foot or about 100 sq foot roofing area.

Instead of giving roofing estimates in square feet, they will give you square measurements. This is what they do by dividing the length of each roof plane by its width and then adding them together.

What is the cost to reshingle a roof?

The national average cost of shingling a roof is $7,200. However, it can vary greatly. Cost to shingle roofs depends on many factors, including roof size, geographical location, shingle material, and other factors.

You can save a lot of money if you are looking to make a small roof repair rather than reshingling your entire roof. Costs for replacing or fixing a few shingles will vary depending on how many they are and what materials were used. The average cost of shingle repairs is $650.

What Is The Cost For Replacing Asphalt Three Tab Shingles

The material you choose is one of the largest expenses that will impact the cost of a roof replacement. The cheapest roofing material is the three-tab asphalt shingles. The average cost of this material is between $150 and $200. This material is however very thin and vulnerable to wind damage.

Cost of Replacing Architectural Asphalt Shingles

Another common type of asphalt is the architectural shingles (30 or 50 years) or laminate shingles (50 or 60 years). Because they are thicker than three tab shingles, these shingles are more durable. It costs about $350 to $500 to install 30-year architectural shingles per square.

Architectural shingles with a 50-year warranty are stronger and considered to be premium. This type of shingle can be purchased for between $450 and $700+ per square.

For premium products like architectural shingles, a quality roofing company should offer a longer warranty. Before you choose your roofing material, make sure to ask about the warranty.

Other than shingles, other factors like labor and other materials can also impact the cost of a roof. What other factors influence roof replacement costs?

Additional Considerations When Calculating Roof Replacement Prices


It may seem simple, but replacing a roof takes a lot more nails than it seems. A typical roofing system will require two boxes of nails.


We recommend adding a waterproof underlayment to your roof as an additional layer of protection from water damage. Underlayment can protect your home from water damage, mold, and other problems caused by water. It is a code requirement that your contractor installs underlayment.

Ice & Water Barrier

Your roof will be protected by quality water and ice barrier. Some formulations can be molded to fit your roof. The water and ice barrier adds extra protection to the roof by keeping water from getting underneath.

Starter Shingles

To keep your roof dry, you will need to use starter shingles. They are below the main shingle, protecting the seams from water. This directs water away from your roof and prevents it from leaking into your home. All manufacturer warranties require starter shingles. However, they can be cut by roofing contractors to save money and time.


Your roof, like all other areas of your house, requires ventilation to allow proper airflow. Lack of ventilation means hot air cannot escape your attic. This can lead to mold and other problems. Ventilation can prolong the life span of your roof, and improve your home’s energy efficiency. These items will not be replaced by unscrupulous contractors to reduce their estimates.

Roof Flashing

Roof flashing can be used to seal seams and other areas that are susceptible so water doesn’t get trapped. Flashing is used where the shingles meet with the chimney. Roof flashing is an item that many estimates do not include. It often involves removing siding, cutting back existing wood siding, or using cement board siding. This is an important area to know. Find out how your contractor or roofing company plans to handle your roof flashing.

Drip Edge

The drip edge is an area of roof that extends beyond fascia. Although it is often overlooked by roofing contractors, if the drip edge is not present, water won’t flow properly into the gutters and can cause rotting. It not only improves the appearance of your home but it is also important to keep insects and water out.

Unforeseen Roof Replacement Costs

Your roof estimate may be higher than you expected, depending on the materials you have chosen. This could indicate that there is other damage to your roof. If your roof was damaged by a storm and you didn’t take immediate action, plywood damage may be possible.

Although you might believe plywood won’t cost much to add to your roof, hurricanes, severe storms, and inflation are all factors that affect the availability of plywood.

Complex roof designs can increase the cost of a new roof. Skylights can be difficult to install so roofers will charge extra to accommodate them.

When estimating the cost of a new roof, roofing companies also consider the type of roof material that needs to be removed, the slope of the roof, and access to the roof.

Roof Replacement Labor

After you have accounted for all the material costs, it is time to add labor. 60% of the cost of a new roof is usually accounted for by labor. It is worth looking into a roofing company that offers very low prices if you are interested in working with them.

Because roofers work where they are needed, labor costs can fluctuate. Roofers are in high demand after major storms such as tornadoes, hail storms and hurricanes. It may be more difficult to find a company if you live in an area that has not been affected by the storms.

Is it a good investment to replace your roof?

Even though it is expensive upfront, replacing your roof can be a good investment. A new roof is expected to last up to 20 years. Depending on many factors, a new roof could increase the value of your home by $10,000 to $20,000 depending on how it was constructed. There are many options available to help you budget for a new roof.
