How Much Does a New Roof Cost? Part I

Have you ever asked yourself what’s one of the most significant expenses a homeowner can have? “A roof replacement.” But, how much does a new roof cost? That depends on many factors such as the style of the roof, the materials used or the size of the house.

Maybe you need to replace your roof because of the damage caused by weather. Perhaps you’re considering getting a new roof to make it more energy efficient or upgrade your home’s aesthetics. Maybe your roof needs replacement because it’s suffered normal wear and tear over time. Whatever the case, the cost of replacing a roof varies widely.

Whether you’re getting a basic replacement or high-end options, the cost of a new roof can range from $5,000 to $10,000.

Whatever the reason for replacing your roof, you’re about to make a significant investment, so it’s useful to analyze all the factors that may impact the final cost and your wallet.



So, how much does a new roof cost?

Roof size matters

Size is the most significant factor when determining how much a new roof costs. As we already mentioned in our post EASY ROOFING GUIDE II: ROOFING SUPPLIES AND KEY DEFINITIONS YOU MUST KNOW, roofers, calculate the cost of a roof replacement concerning roofing squares. So, one roofing square is 100 square feet (10 feet by 10 feet). That is why it’s vital to know how many roofing squares you’ll need to replace so you can calculate costs.  Notice that the roof of an average residential home has between 23 and 35 roofing squares.


Roof removal costs

You may be thinking about getting a new construction but keep in mind that before the roofer starts installing your roof, he has to remove the existing one. Notice that the cost of roof removal varies depending on the size of the roof and the current materials.

You can expect to pay $100-150 per roofing square to remove a single layer of asphalt shingle roofing; $115-165 for a double layer; or even $125-175 for a triple layer.

Roofs made of more substantial material may result in higher costs.


Removing old shingles

No matter if you’re a roofing contractor or a DIYer, removing the old shingles is the hardest part of the job. Depending on the area you live, the cost of a tear-off varies widely. If you take on the job as a DIY project, you can save about $1,000. But, remember that safety comes first, so you better hire a pro.


Roof materials

Roofing materials also impact the cost of your roof replacement. For example, asphalt shingles are the most common, widespread and low-cost material in the United States.

Get ready to pay between $120 and $400 per roofing square for an asphalt shingle roof but remember that it will also depend on the area where you live.


Different styles for different roofs

The shape and style of your roof will play an essential role in determining the cost to replace it. The steeper your roof’s pitch, the higher the costs will be. Want to know why? That’s because steep roofs are tricky to walk on. If you have a steep roof, the roofer will need extra safety equipment (such as harnesses) to perform the job.

However, flat roofs are also tricky. They need regular maintenance and may have to be replaced every ten years. Some other roof features (chimneys or skylights) also affect how much you’ll pay. Roofers must work around these type of features, which slow the project progress and raise costs.


New roof installation vs. roof repair

Just because your roof leaks doesn’t mean you need to ask for a roof replacement. At Bay 101 Roofing, we recommend you distinguish the cost of a new roof (almost $6,500 on average) versus the cost of a roof repair ($550). Quite a difference right?

Consider replacing your roof when:


Its service life is ending: Most roofs last about 20 to 25 years. So, ask for a roofing inspection if yours is near that age.

There is extensive leaking: If there are multiple or extensive leaks, you’ll probably need to replace the whole roof instead of just repairing the leaks.

You want to improve your home’s appeal: Recoup around 50% of your investment for a new roof that complements your home’s architectural style.

You want to become more eco-friendly: Cool-roof technology has spread up the last couple of decades. It’s an excellent way to make a long-term investment and help the environment.


Let’s talk about prices: HOW MUCH DOES A NEW ROOF COST?

The average homeowner in the US pays about $6,600 to install a new roof. There are of course certain cities like Denver ($7,500) being higher than average, while others remain below average like Austin, TX ($6,100).  Keep in mind that prices can fluctuate depending on many factors, including roof size and pitch, type of application, roof materials and the number of layers, home location, roofing code requirements and even roof features. Check our post DISCOVER THE COST OF A NEW ROOF to know a little more about these factors.

But first take a look at this prices for a new roof in the US:


  • National Average Change Location $7.293
  • Typical Range $5.112 – $9.794
  • Low End $1.200
  • High End $30.000

What You Need to Know When Installing a New Roof

Building Modern House Construction with metal roof, rain gutter

Some homeowners may think they don’t need to worry about installing a new roof until the old one starts leaking. Wrong! Those who wait that long then have to deal with higher fixing costs. Why? Because by the time you notice the leaks, the structural damage will have already occurred.

Want to know if it’s time to install a new roof? Here are some tips:


  • How old is the existing roof? Asphalt shingles, for example, should last about 20 to 25 years, even longer, if they are installed correctly and with suitable materials. If you’ve been living there for many years and you don’t have an idea when was the last time your roof was replaced, it’s time for a roof inspection.
  • Go outside and take a look at your roof. Check if the shingle lines are still straight or if they have any sags. A sag is a clear signal of rotting in the sheathing.
  • How to know if the asphalt shingles are breaking down? You can figure it out when you start finding granules in the
  • Look at the tabs and check if they are intact. Can you see any cracked, curled or misshapen shingle? Is there any shingle missing? Remember that as time goes by, shingles start deteriorating.
  • It’s time to visit the attic. Is there any sunlight going through the roof boards? Try to inspect the attic just after a good rain to look for moisture or leaks.


How many of the previous warning signs did you notice on your roof? If you checked at least one, you better ask for a qualified roof inspection ASAP.


New roof and roof replacement
Know what you need for a new roof.


One decision you’ll need to make once you decide to get a new construction is whether to remove the old roof completely or cover the existing roof with a layer of new shingles.

Homeowners can save up to 25% or more by reroofing instead of a tear off and build a new roof completely. Is that a smart decision?

Roofing experts disagree on re-roofing. That’s because tearing down the roof is the best way to find water damage that would otherwise remain discovered.  Besides, adding a second layer of shingles could be harmful as you are adding extra weight to the roofing structure. It may seem that the best decision is getting a new roof but, not so fast!

On the contrary, some organization such as the National Roofing Contractors Association and the Asphalt Roofing Manufacturer’s Association consider re-roofing as a reasonable option. They say re-roofing can be a good practice if it is approved by local building codes.

Some factors to consider once you make the decision to get a new roof or ask for a roof replacement include:


  1. The existing roof must be in good conditions. The roofing materials need to be compatible with reroofing.
  2. The best condition is when you can see the roof’s underlying structure directly from the attic.
  3. To make sure the warranty applies, it is critical that the roofer follows the shingles manufacturer’s instructions as well as the local building codes.
  4. Expert roofers must keep in mind that re-roofing requires very different installation techniques than the standard methods.
  5. The weakest areas in any new roof are chimneys, valleys and other surrounding protrusions.

We all agree the roof is arguably the most important part of the house. It protects our family and belongings while keeping water out of the building.

We also agree it isn’t an enjoyable task to pay for a roof replacement, less when you have to spend $8,000 to $20,000 on the work.

For that kind of money, you better make sure the job is done right. So, here’s what you need to know when getting a roof replacement:


  1. Shop around: Never choose a roofing company based on price. You must be extremely careful whom you hire. Some roofing contractors deliver pretty low bids because they hire low-wage workers. Before hiring a roofing agency, get as many references from neighbors as you can. Checking some roofing manufacturer websites (such as,, is a good choice to look for lists of certified roofers.


  1. Strip away the old: Your roof can have two layers of asphalt shingles. But, if there’s only one in place, you can install a new layer right on top. That way you’ll be saving around $1,000 but the roofer won’t be able to inspect and repair the decking and flashing underneath.


  1. Go top shelf: The best way not to worry about your roof for a long time is to purchase highest quality products. This includes opting for 50-year-shingles ($300 to $500) or copper flashing.


  1. Pay attention to the paperwork: Three documents are essential when getting a roof installation:


  • Specify all the agreed-to details, supplies, as well as costs of a new roof on a written contract.
  • Some cities require a building permit for roofing projects. That ensures that your contractor follows all the building codes.
  • A letter from the contractor’s insurance that confirms the coverage of the project for the roofer’s worker’s compensation as well as the liability plan.


  1. Do not pay until you see the magnet: Contractors have a tool (a giant magnet on wheels) that makes it easy to pick up all the nails and metal that land on your grass while they’re working. Avoid getting a flat tire or any injury. Once the job is completed, ask your roofer to bring the magnet and leave the area free of metal waste.
