How Much Does a Shingle Roof Cost? 

Your roof is an important part of your house and needs to be kept in the best shape possible.  Even with good maintenance and upkeep over the years, every shingle roof will eventually need to be replaced.

Replacing your roof is a big project and a big decision, but it’s likely not as expensive – or as difficult – as you might think. The two main factors determining cost are size of the roof and the difficulty factors associated with replacing it.

All in all, we estimate replacing a roof in Arizona costs between $8500 and $15,000. This is quite an expansive range – so let’s take a closer look at what goes into a new roof installation.


cost of a shingle roof

Roof Size

Materials are usually priced by the square foot. Most quotes are then based on the square footage of your home’s roof. (Don’t confused this with your home’s square footage, which will be a much higher number!)

A term you’re going to hear a lot when obtaining a quote is roofing square. A roofing square is the measurement contractors use when estimating how much material (tiles, underlayment, etc.) are needed. It’s shorthand for a 10’ x 10’ area, which equals 100 sq ft.

  • One Roofing Square = 10’ x 10’ area or 100 square feet
  • A 2,000 square foot roof = 20 roofing squares

In Phoenix, on average, you can expect to pay about $4.00 per square foot for all project materials. This includes shingles, some type of roofing cement, nails and underlayment. But keep in mind that not all roofing materials are created equal. Asphalt shingles cost less while metal, composite, and slate shingles are more expensive.

4 Key Difficulty Factors

1. Pitch & Slope

After size and materials, the roof’s pitch is the second largest determinant of cost. You can expect to pay more for a roof with a pitch greater than 6:12, as this is considered a “non-walkable” pitch and requires additional preparation and equipment to ensure safety and proper completion.

1-pitch and slope

Roof pitch also determines how underlayment is needed. Industry standards say that roofs between 2:12 and 4:12 pitch should have two layers of felt or underlayment installed.

Compare that to a flat roof with a pitch of about ½ :2:12 and 2:12, which usually require less underlayment to meet fire rating regulations.

2. Removal & Disposal

Removal and disposal of the current roof can also affect price on a per-project basis.The more time needed to tear off and haul-away the old roof, the more expensive the job will be.

3. Accessibility 

How hard is getting on your roof?

Will it be difficult to dispose of your old roof, or haul all the new materials on top of your roof? If additional equipment is needed, you can expect labor costs to climb.

4. Repairs

Having other issues repaired while putting in a new roof is pretty common. Common problem areas are usually wherever something is cut into the roof: skylights, chimneys, vents, etc.

Putting in a new roof is also a good time to evaluate the condition of the wood underneath. Contractor should bring any repairs needed to your attention, as part of the estimate, and this can also be a good opportunity to ask about wall deck installation.

guys talking about cost

Here’s a look at how much a new roof will cost you based on the type of shingles you decide to install:

  • Asphalt Shingles (3 Tab)  = $7,500 to $12,500
  • Wood Shingles = $ 15,000 to $25,000
  • Steel Shingles = $15,000 to $27,000
  • Aluminum Shingles = $ 16,000 to $28,000
  • 30 Year Shingles  = $9,500 to 15,500
  • 50 Year Shingles = $11,500 to 22,000

 Some types of shingles are more expensive than others. Choose a material or style you can afford, obviously – but don’t skimp out. Spending more on good quality materials will pay off.

INSTALLATION COSTS (Re-Roofing & New Roof)

cost to install new shingles

Here’s a breakdown of the installation costs associated with installing a new shingle roof or re-roofing.

Asphalt Shingles

Since asphalt shingles are so light and easy to install, they are usually the least expensive to have installed professionally, requiring less time and effort than other materials. Labor costs for roofing jobs can cost anywhere from $30 to $80 per hour.

A roofing underlayment is usually recommended prior to installation, to keep water from damaging the roof deck. Flashing will need to be done around joints and valleys, and ridge capping must be done around ridges. The shingles themselves are usually held in place by nails alone.

If you’re installing asphalt shingles on a typical 1,500 to 2,000 square foot roof, you’re probably looking at between $6,000 and $10,000 for materials, labor, etc. Most typical jobs end up right around $8,500. Keep in mind, when it comes to asphalt shingles, you normally have the option to overlay an existing set of shingles which discount your installation costs significantly.

Metal Shingles

Metal roofing is versatile and can work on a variety of roofs. It’s lightweight and can be fitted to both steep and gradually-sloped roofs. In some cases, it can even be put on over existing asphalt roofing – saving you the trouble of tearing off the old roof.

Metal shingles are expensive, both for materials and for installation. Installing metal roofing requires expertise, time, and the right tools to complete the job:precision in fitting and affixing each panel is important and it might take twice as long to put in a metal roof as an asphalt roof. Metal roofing will also need a synthetic underlayment to repel moisture and allow it to escape.

Exact cost depends on the material and style used, but steel or aluminum shingles will typically cost you between $7 and $10 per square foot, or between $700 and $1000 per square.

For a typical 1500-square foot roof, that comes out to somewhere between $10,500 and $15,000 for materials alone.Toss in additional materials and labor, and a new metal shingle roof can cost $15,000 and $20,000 – or about $1,000 to $13,333 per square.

Composite Shingles

Because they are so lightweight, composite shingles are easier to install than metal or slate shingles. They don’t usually require the same equipment or time needed to install metal roofing, but you should expect them to be time-intensive than installing regular asphalt shingles. They’re also far less expensive than real wood shakes.

For the cheapest, most basic styles (imitation asphalt), you can expect to pay between $4-$6 per square foot to have them installed professionally, or about $400-$600 per square. For higher-quality shingles, you might be looking at $600-$800 a square, or even $1000 for shingles from top of the line brands.

That’s a lot more than asphalt – but a lot cheaper than metal tiles! Some styles cost more than others; imitation wood shake or slate generally run on the higher end of the scale.

Fiberglass or Organic Shingles

You can grab regular old asphalt shingles from any home improvement store for roughly $100 to $125 a square, or $1-$1.25 per square foot. In-store brands like Lowe’s and Home Depot make great asphalt shingles that don’t break the bank, and in a variety of styles.

Organic shingles are usually expensive than fiberglass shingles, but it can vary by brand, make, warranty, etc.

Architectural Shingles

Architectural shingles can cost like $150 to $200 per square.One good brand of architectural shingles is Atlas; they have a wide variety that look like both asphalt and wood shingles. Another CertainTeed; their Landmark shingle looks like cedar shake and has a 10-year Algae-free warranty.

guide for buying shingles

Aside from cost, when selecting new shingles you’ll want to consider style and durability. Below we breakdown each type of shingle and what you need to know.


This is one is subjective but pick a style that works with your home! Wood shake looks better on certain houses than slate, and metal shingles look a lot better on modern homes than asphalt.


Shingles are subject to everything – rain, wind, snow, hail, heat, sun. They need to be durable enough to stand up to all these without splitting, cracking or warping. Asphalt is the most susceptible to weather factor, while metal is usually the most durable. Resistant to mold, mildew and insects is also good.

Durability will also determine how long your roof lasts; you can expect an asphalt roof to last 10-20 years, while metal or plastic roofs might last 30 to 50 years.

Roof shingles aren’t all made of asphalt – they come in a variety of different materials and designs to fit the many different home styles and aesthetics out there. Some of these materials cost more than others.

Types of Shingles

Asphalt Shingles

Asphalt shingles are by far the most popular style of the roofing shingle. They’re cheap, easy and quick to install and easy to replace when damaged or worn. In fact, they’re one of the few things in life where you can actually have good, cheap, and fast – all at once.

Asphalt shingles are great choice if you’re on a budget. They have a typical lifespan of 10-20 years, and can sometimes be recycled when you’re done, turned into new shingles for another

The major downside to asphalt shingles is that they aren’t the most durable and can be susceptible to extreme weather and high winds. They also need some periodic maintenance to keep the roof looking its best and have been known to snap or crack in very cold weather. When shingles do wear out or break, they tend to look crummy.


  • Inexpensive
  • Easy to install
  • Lightweight
  • Come in organic, fiberglass, architectural styles


  • The least durable
  • Affected by wind, storms
  • Shortest lifespan (10-20 years)
  • Need periodic maintenance


Metal Shingles

Metal roof shingles were once reserved for expensive luxury homes, but they’ve become more affordable and popular in recent years. Many homeowners choose them for their strength and durability; metal handle rain, wind and weather better than any other roofing material, and can last more than 50 years. That’s a lifetime compared to the 15 or 20 years a shingle roof can last!

Metal shingles aren’t susceptible to rot or insects the way wood shingles can be. They’re also totally fireproof.

Metal heats up quickly in the sun, and metal shingles are thus better at shedding snow than asphalt or especially plastic shingles. And since they reflect radiant solar heat, they can help keep your home cooler in the summer – cutting down your cooling bills by 20-25%.

Here in Arizona, that’s a lot!


Metal roofs reflect heat

The bright side is that, installed properly, that metal roof will last upwards of 50 years – making that large number a worthwhile investment.

Interlock is a popular brand for metal shingles and roofing. Their metal cedar shingle and metal slate options easily pass for the real thing – and have lifetime limited warranty.

Installing Metal Shingles


  • Durable and lightweight
  • Waterproof, rot-resistant, mold-resistant
  • Can last 30-50 years
  • Good for shedding snow, water
  • Can save on cooling costs
  • Come in variety of styles


  • Expensive
  • Difficult to install / More expensive to install


Composite Shingles

“Composite” shingles, also referred to as synthetic or plastic shingles, are made from a synthetic material or combination of materials. They are manufactured from polymer, plastic or rubber. Fiberglass asphalt shingles, for example, are a type of synthetic shingle. They are usually designed to resemble another popular style shingle like asphalt, wood shake, slate or tile. You might be surprised at how many wood shake roofs you see are actually composite shingles.

Composite shingles are great for durability; they’re very thick and strong, and they don’t split or warp. They are also fire-resistant, as well resistant to moisture and even to mold and mildew growth. They can last last 30 to 50 years. You can’t say that about real wood shakes, which is why so many people are using switching to composite instead.

They also come in virtually any style you could want for your home: imitation wood or cedar shake, imitation slate, terra cotta.

  • Moderately priced
  • Durable; don’t crack
  • Moisture-Resistant
  • Mold/Mildew-Resistan
  • Designed to look like wood, slate, etc


  • More expensive than asphalt
  • Can take longer to install


Fiberglass or Organic Shingles

Fiberglass and organic shingles have asphalt coatings, however organic shingles have a paper or wood inner core, while fiberglass shingles have a fiberglass core under the asphalt (who would have guessed?). Of the two, organic shingles tend to be heavier and longer-lasting, as they have more asphalt than fiberglass ones.

Architectural Shingles

There are also architectural shingles, a kind of fiberglass shingle that’s heavier-duty, thicker and more textured, as well as more ornate; they are usually designed to resemble wood shakes or shingles from a distance.

What Shingles Are Best for Your Home?

That question really depends on the look you’re going for, but also your budget. Asphalt shingles are the cheapest by far, and the easiest to install; they’ll have the fastest installation time and lowest labor costs. But they aren’t the most durable and will usually need upkeep or repair 10 years down the road.

Metal shingles are the toughest and longest-lasting, but also the most expensive and time-consuming to install; a metal shingle roof could easily take 2x as long to put in as a shingle roof and cost 2-3x as much. The good news is that they last decades and are impervious to wind, rain, bugs and rot.

Composite/Synthetic/Plastic shingles are a good middle road – more expensive and durable than asphalt shingles, but not as pricey as metal shingles. They can also often last 30+ years and require less maintenance and upkeep than asphalt shingles. They usually take longer to install than asphalt shingles but not as long as metal shingles might.

Hiring a Roofing Installer

Warranty: Warranties are important for all roofs and can have a pretty large impact on install price. Most roofing companies offer a two-year installation warranty.

You can expect a 10–20-year manufacturer warranty on any materials used. Some high-end shingles even have lifetime warranties. It’s important to note, however, that if the roof is not installed to the manufacturer’s specification and intended use, the warranty will be void.

It’s uncommon to inspect a roof and see that the manufacturer warranty is compromised due to improper installation

Licensing and Insurance: Always ensure that any contractor you hire is fully licensed, bonded and insured. If possible, ask around for recommendations or talk to people who have used the contractor before. You want to know that you are working with a reliable and professional team, who is covered in case anything goes wrong during installation. Also, ask them what kind of warranty they offer and double-check the exact terms of that warranty.

Go Local: The best roofing contractors are always local. They know the local regulations and building codes they need to adhere to, as well as what a roof in your area needs to hold up to weather. If they’re good, they’ll also have a trusted reputation in the community that you can rely on.

DIY Installation to Save Money

While regular asphalt shingles are easy to install and you can often put them in yourself, other materials (like metal) take more skill, experience, time and equipment to put in right – and are best left to professionals.
