Just the other day, a really good friend asked me a question about roof pricing.
His exact words were pretty straightforward, “Luke, if I want to replace my roof, how much does a new roof cost?“
While there are differences in roof repairs vs a brand new roof cost, the right follow-up questions and this article can help you figure out how much a new roof should cost you.
You might be surprised to know that based on answering some simple questions and some rough calculations, knowing how much a new roof will cost isn’t hard to figure out.
Today, we are excited to share with you two amazing features:
- Our roof replacement cost & build feature
- This article helps you understand all the pricing metrics behind new roof costs!
New Roof Costs (Everything to Know!)
Today, in our article we will be sharing new roof costs from a homeowner’s perspective as if they’re replacing their existing roof.
In other words, when we refer to “New Roof” we are referencing new shingles and underlayment for an existing home, not a new construction home.
Understanding what makes up a new roof or roof replacement is the key to estimating the cost of your new roof. A high-quality roof replacement will consist of the following:
- Removing the existing shingles and underlayment
- Inspecting the condition of plywood on the roof (we will never put new shingles on plywood that is damaged)
- Installation of underlayment – Certainteed DiamondDeck
- Application of ice shield, CertainTeed Winterguard along edges
- New shingles (selected below)
This is of course standard with any new replacement that Top Dog Home Pro does and is all included, aside from any damaged plywood that requires replacing (we will dive further into extras later).
And while this seems pretty straightforward, the reason we let you know about what a new roof first consists of is that though rare, some companies in the past have simply installed a new roof on the existing roof to cut corners.
So now that you know what exactly a roof replacement consists of, let’s look at the costs.
How roof replacements are priced:
Roofs are priced by what is commonly referred to in the roofing industry as a “Square.”
A roofing square is equivalent to 100 square feet of shingles.
For example, a townhome that has 1,000 square feet of roof would require 10 “Squares” of shingles. Almost all companies use this term to price roofs and costs such as underlayment, tear off, etc are factored into the square price.
Factors that determine the amount of square required for a roof include:
- The size of your home,
- The pitch,
- The slope,
- Chimneys, skylights, and areas that require more shingle usage
Now that you know how roofs are priced, let’s explore the three major components of new roof costs!
3 Factors that Determine New Roof Costs
When it comes to your new roof costs, there are three determining factors that will increase or decrease the price. Obviously, the first is the size of your roof, followed by the shingles. Within the size of your is the roof’s pitch and type of roof, followed by extra or additional costs.
- Roof size and pitch/type
- Roofing shingles you select
- Roofing extras
1. New Roof Cost: Size of Home’s Roof
The size of your home’s roof matters when it comes to pricing (this is a given).
A townhome with a roof that is approximately 10 square is naturally going to cost less than a single family home with a hip roof that requires 30 square.
That being said, on our Roof Build & Price page, we let homeowners pick out the features of their roof and get a rough ballpark estimate for what their roof will cost!
As you can see in this photo below, the amount of square (roughly estimated) per type of home is as follows:
The following averages are common for each of the following types of homes:
- Townhome: 10-12 roofing square
- Single Family Home: 20-25 square
- Extra Large or Hip Roof: 35-40 or more square
While the exacts are actually measured using GPS technology and satellites provided by EagleView so that slope and pitch are spots on, the final amount of shingles that are needed come from these reports.
However, this will help you get a roof ballpark for what you will need square-wise to estimate your roof cost, but first, you have to pick your shingles!
2. New Roof Pricing: Type of Shingles
The type of shingle you select for your new roof matters in more ways than just price.
For starters, the shingle warranty, the quality of the singles you select, and what type you ultimately choose all have features that can make them better (or worse) than another asphalt shingle.
Think of shingles like cars.
You have a base model car, followed by your average model, followed by the top-end model. Shingles are very similar.
Here at Top Dog Home Pro we offer three shingles, though we hardly install the first:
- Three-tab shingles (base model)
- Landmark Architectural Shingles (consumers top pick)
- Landmark Architectural Pro Shingles (best warranty)
To help, we have included this pricing table below which includes the three shingles we offer
|Type of Shingles||Townhome||Single-Family||XL Home/ Hip Roof|
|10 Square:||20 Square:||40 Square:|
|XT25 Three Tab||$4,000||$8,000||$16,000|
While this is based on square footage averages for the normal roof for a townhome, single-family home or an extra-large home, what you will first notice is that the price difference between basic three-tab shingles (XT25) and Landmark Pro Architectural shingles is typically a couple hundred more…
Why does this matter?
For starters, the material and quality of an architectural shingle are worth every penny compared to the lesser three-tab counterpart, but REALLY, it boils down to the shingle warranties.
In our warranty article we explain the specifics of roofing warranties, but for a quick glance here is a comparison:
|3 Tab Shingles||Landmark PRO|
|-25-year, limited transferable warranty|
-5-year SureStart™ warranty (100% replacement and labor costs due to manufacturing defects)
-10-year StreakFighter® warranty (on available colors) against streaking and discoloration caused by airborne algae
-5-year, 60 mph wind-resistance warranty
|-Lifetime limited warranty|
-15-year algae resistance
-10-year SureStart protection includes
-15-year 110 MPH wind warranty with an upgrade to 130 MPH available
3. New Roof Cost: Extras
You have your home’s roof size figured out… check ✅
You selected your shingle style… check ✅
Next, it’s time to see if any extra is needed or if you want to add extras to your roof! These types of things are always discussed prior and included in pricing, with the only thing not being discussed upfront being the plywood replacement.
Hopefully, we don’t have to replace any plywood, but that is something that can happen with a new roof and it isn’t known until the old roof is torn off. Our team can sometimes feel “Soft Spots” ahead of time and roughly guess how many boards may need replacing.
That said, here are common extras that can sometimes impact new roof costs or homeowners may want to add:
|Extra||Unit of Measure||Price|
|4 Ply 1/2″ Plywood 4×8||each||$65|
|An additional layer of tear-off||per square||$35|
|Tear Off of Wood Shake||per square||$55|
|Steep Pitch 8/12 or >|
|Ridge vent||per foot||$4|
|New Skylight||each||Varies ($1,000)|
|Pipe Collar and Permaboot||each||$35|
|Power attic fan||each||$550|
|Eagleview Roof Report (If not submitted)||per home||$40|
As you can see the extras vary and some are necessary (like the ridge-vents) and some are extras for curb appeal (like adding a skylight).
Things like an extra layer tear-off (older roofs that have two layers of shingles) or cedar shake tear-off require long amounts of time and are not included in the normal price.
As mentioned, these things are all talked about and discussed in the price upfront, however, these are the extras that can be added to a new roof cost.

Frequently Asked Roofing Cost Questions
Depending on the shingles and the size of your home’s roof/the home layout, a 2500 square foot roof would require at least 15 square of shingles, in that case costing in between $8,000 and $18,000 depending on factors such as location, shingle type, and supply.
The national average for a new roof is around $8,000 to $10,000. Obviously, factors like the size of your home’s roof and the type of roofing material matter. That said, use the pricing guide below to find out how many squares of roofing you need.
One square in roofing terms refers to 100 square feet of shingles or roofing materials. Roofers will measure a house based on “Squares” since shingles come in 100 square feet bundles. A house that is 10 square has a roof that is 1,000 square feet.
