We’re professional roof consultants – professional roof experts, you might say. People often ask us what the best asphalt shingles are. The answer we give isn’t always the same.

You have to consider a lot of things before you can say what the best shingles will be for a particular roof. There is no one single answer.

Different people have different roofs in different environments, and they have different concerns and expectations for their roofs.

To figure out what the best shingles for your roof will be, you have to take a few things into account:

Your Roofing Budget

Does it make sense to spend money on the ultimate performance shingles right now? Is it really necessary? If not, the asphalt shingle brands listed below offer the best roofing shingles for every budget.

The top performance shingles from any particular shingle manufacturer will typically cost roughly two to three times as much as their cheapest shingles.

Roofing labor costs are normally anywhere from 40% to 60% of the total cost of a shingled roof installation, depending on the details of the job. The cost of labor in roofing is virtually unaffected by the quality of the materials; cheaper shingles aren’t going to reduce labor costs.

Many people try to reduce the cost of their new roof by reducing material costs. Going with the cheapest shingles instead of the most expensive shingles might reduce the cost of your new roof by as much as 20% to 30%.

This can mean 1000’s of dollars in savings on the roofing project, but it might not really be worth saving 25% on new shingles for a roof that will only last half as long.

It’s something to think about.

Of course, using either the most expensive shingles or the least expensive shingles aren’t your only choices. The best shingle manufacturers offer many options in between. In fact, these middle-tier products tend to be the most popular shingles.

Roofing labor normally costs anywhere from 40% to 60% of the total cost of a roofing project.

Your Geographical Location

Do you live in a place where severe hail will be a concern? Do you live near the coast or in some other high wind area? You’ll want high-end asphalt shingles with the top impact or wind resistance ratings.

Your Future Plans for Your House

Are you going to keep your house or sell it? A new roof will definitely increase the resale value of your home, but there’s more to it. Will a transferable roof warranty be a selling point? You’ll want shingles from a company that offers you a good selection of warranty upgrades.

Appearance (Compatibility)

You’ll want a roof that complements your house. Some of these manufacturers offer shingles in colors that the others don’t have. Shingle colors and styles have proliferated in recent years, and available styles also vary from brand to brand.

You’ll want to browse the available shingles on these companies’ websites to find the perfect color and style for your house.

Roof Complexity

Do you have hips and valleys and dormers and skylights all over your roof? Workmanship will be even more important than usual. You’ll want a top-notch contractor who is already familiar with the material.

You’ll probably want to hire a contractor who is certified by the manufacturer, and you’ll want to use shingles from a manufacturer who has a contractor certification program.

So, what are the best roof shingles?

The best shingles on the market today are shingles from a top performance line from one of the top shingle manufacturers.

There is a group of shingle manufacturers who all have very similar experience, high manufacturing standards, quality products, and good reputations. The top roofing shingle brands are all highly competitive when it comes to warranties, product lines, prices, etc.

When one of them adopts a new shingle technology, the others usually aren’t far behind. Whether it’s algae-resistant shingles, Energy Star-certified reflective shingles, improved self-sealing strips…all of these companies stay up-to-date and continually roll out new products that take advantage of state-of-the-art developments.

This group of companies produces the best roofing shingles, and we’d be likely to recommend shingles from any one of them, depending on the roof in question.

We put together this list of the best roof shingle manufacturers to get you started off looking in the right place, and to make sure you can feel comfortable with the shingles you end up using.

Why You Want the Best Roof Shingles

Roof Performance

The best roof shingles perform better. High winds, hailstorms, constant sun…the best roof shingles can handle whatever the environment throws at them.

They will be less likely to develop leaks, leaks that can seriously damage your house and the things in it. They will also be less likely to develop other common roof issues that will cost you money to repair.

Roof Longevity

The best roof shingles last longer than lower-quality shingles, often much longer, which can more than make up for the higher initial material cost. They will be less likely to fail prematurely or unexpectedly, meaning that you won’t have to deal with the headache of having your roof replaced again for a very long time.

Life-Cycle Cost of the Roof

The best roof shingles will cost you less in the long run. Whole-life cost (or life-cycle cost) is the total cost of ownership over the life of an asset.

Life-cycle cost analysis is an established asset management technique, and it typically shows that using high quality roofing materials reduces the total lifetime cost of a roof by reducing required maintenance and repairs as well extending the useful life of the roof.

When you use the best roofing material, you typically end up getting more use out of your roof per dollar spent on the initial roof installation than you would for cheaper materials.

Insurance Discounts for High-Quality Roofing

The best roofing shingles can save you money on your homeowner’s insurance. Discounts for a new roof installed with highly-rated performance shingles from a top shingle manufacturer may help you save up to 20% on your homeowner’s insurance policy premiums.

Resale Value of Your House

The best roof shingles will help increase the value of your home and help preserve that value over time. For the money invested, compared to other home improvement projects, your roof has an outsized effect on the resale value of your house.

What the Best Roof Shingles Have in Common

Personal opinion often plays a big part when someone tells you what they think the best roof shingles are. Personal experience with a company, a preference for a certain style of shingle, etc.

But there are some things about shingles that are simply factual and often measurable. You can use these criteria as a guide to selecting the best roof shingles.

Production Quality

The best roof shingles are manufactured to high standards, using industry best practices, with a final product that is consistently satisfactory.

This short video from CertainTeed shows you the basic steps involved in asphalt shingle production:

CertainTeed Roofing - How Shingles Are Made

High production quality means your roof will be far less likely to suffer from the common problems that affect asphalt shingle roofs.

Shingle problems that are frequently due to manufacturing defects include premature shingle cupping, clawing, and curling; cracked shingles, loss of granules, blisters, and failure of the self-sealing adhesive strips.

These issues can often be seen on old roofs where the shingles have reached the end of their design life. But shingles produced with poor manufacturing quality can start to develop these issues almost as soon as they’re installed.

Of course, you won’t be able to observe your shingles being made or see the actual quality standards being enforced in the factory, so you’ll just have to take the manufacturer’s word for it. Which brings us to manufacturer reputation.

Manufacturer Reputation

The best roofing shingles are made by a manufacturer with a great reputation. A great reputation is the result of years of producing quality products, treating their customers well, honoring their warranties, and being honest about what their products can and cannot do.

If a manufacturer has a good reputation, that’s as good a sign as any that you will get what you pay for when you buy from them. All of the companies listed below have a good reputation within the roofing industry.

Shingle Thickness

The best roof shingles are relatively thick. This is something that holds true across all roofing materials in general. Everything else being equal, the best roofing material will be a thicker roofing material.

Thicker material will last longer and perform better than a thinner version of the same type of roof covering.

Polymer Modified Asphalt

The best asphalt shingles use polymer-modified asphalt, also called “rubberized” asphalt. Much like the modified bitumen roofing used on flat roofs, 3% to 12% of a polymer-modified shingle is synthetic rubber, styrene-butadiene-styrene (SBS), blended into the asphalt during production.

Polymer-modified shingles perform better in extreme cold, high winds, and hailstorms. They are more resistant to cracking or tearing than regular asphalt shingles.

If you live in a region where sub-freezing temperatures are common in the winter, where high winds are a common event, and especially if you live in a place where both apply (like the New England coast), polymer-modified shingles will (statistically speaking) be worth the money.

Impact Resistance (Hail Damage Protection)

When you’re talking about impact resistance, you’re talking about how well the shingles can stand up to hail. Impact resistance ratings for shingles go from Class 1 to Class 4, with Class 4 being the most impact-resistant.

A Class 4 impact resistance rating can help residential property owners to obtain a reduction in their residential insurance premium. The best roof shingles will have a Class 3 or Class 4 impact resistance rating. The highest impact resistance is normally achieved by polymer-modified shingles.

Fire Rating

Fire ratings for asphalt shingles go from Class A to Class C, with Class A having the highest fire resistance. The best roof shingles will have a Class A fire resistance rating.

Wind Resistance (Wind Damage Protection)

This is another big one. Shingle damage due to high winds is super common. Low-quality shingles will tear, crack, or even lose their tabs in a windstorm. If you live in an area with above-average wind conditions, you’ll want to pay close attention to this.

The best roof shingles will be covered for wind speeds up to 110 mph right out of the package, regardless of who installs them.

Depending on the manufacturer and the product line, this coverage can be upgraded for wind speeds of 130 mph, 140 mph, 150 mph, or even 160 mph if the roof is installed by a certified roofing contractor following (much) more stringent installation guidelines from the manufacturer.

Avoid wind damaged shingles like this by using the best roof shingles.
The best roof shingles will greatly reduce the risk of costly wind damage to your asphalt shingle roof.

There are two different test standards used to determine the wind resistance of asphalt shingles. These standards test shingles in different ways and for somewhat different performance criteria. Either or both may be used to rate shingles.

ASTM D3161, “Standard Test Method for Wind Resistance of Asphalt Shingles (Fan Induced Method).” This standard rates shingles as Class A (60 mph), Class D (90 mph), or Class F (110 mph). Class F is the highest rating and the best roofing shingles will have this rating.

ASTM D7158, “Standard Test Method for Wind Resistance of Asphalt Shingles (Uplift Force/Uplift Resistance Method).” This standard rates shingles as Class D (90 mph), Class G (120), and Class H (150 mph). Class H is the highest rating and the best roof shingles will have this rating.

Manufacturers generally just state the top windspeed that their shingles will resist (or are warranted to resist). You can always find the wind resistance information for any particular product by looking under the warranty information on the manufacturer’s website.

Warranty Coverage (Wind Speeds & Number of Years)

The best roof shingles will come with a non-prorated material warranty good for at least ten years. The length of the non-prorated period of the warranty is the real clue as to how confident the manufacturer is that these shingles will perform, and that they will keep on performing.

The best roof shingles will have warranty options that allow you to extend the non-prorated period (up to 50 years in some cases) and increase the maximum windspeed covered.

What Shingles Do Roofers Recommend?

We’ve worked with many different roofing contractors, and they all have a favorite roof shingle manufacturer, almost always one of the ones on our list.

If you search the internet and read the shingle reviews and shingle recommendations on roofing contractor websites, you will find plenty of roofing contractors telling you that one or another of the shingle brands listed below is the best.

The reasons they give for recommending a particular brand of shingles tend to be the same reasons no matter which brand they are recommending. Quality. Reliability. Performance. And that’s fine, because all of those reasons apply to all of the shingle companies on our list.

The truth is that roofing contractors tend to recommend shingles made by the shingle manufacturer with which they have a professional relationship.

These shingle manufacturers train, certify, and recommend roofers. They have loyalty programs. They offer material discounts to roofers who consistently use their products instead of someone else’s. They offer better warranties to customers who use their preferred roofing contractors.

But just because a roofer gets a discount on shingles and gets improved warranties to offer their customers doesn’t mean that they’re being dishonest when they recommend a brand of shingles.

Roofers normally join loyalty programs and become manufacturer-certified because they were already a fan of the manufacturer in the first place. And since all of these companies produce excellent shingles, why wouldn’t they recommend the brand of shingles that they install the most?

Types of Asphalt Shingles & Modern Shingle Categories

For more extensive explanations of shingle types, categories, and grades, please our article Types of Asphalt Roof Shingles • Asphalt Shingle Categories.

3-Tab Shingles

Three-tab shingles are generally the lowest-tier asphalt roofing shingles. 3-tab shingles are strip shingles with cut-outs that make the shingle strip look like three smaller individual shingles (the “tabs” of the shingle).

3-tab shingles consist of one single layer of shingle material: a reinforcement mat sandwiched between two layers of asphalt with surface granules on the top side.

For a long time, 3-tab shingles had a standard length of 36 inches and a standard width of 12 inches. Roofing manufacturers have recently started to change this, however, and a length of one meter (a little more than 39 inches) is becoming more common.

Strip Shingles

Strip shingles, also called “3-tab” shingles today, are the most basic type of asphalt shingles.

The term “strip” was first used because the individual shingle unit was manufactured in a strip that connected what appeared to be two or three separate shingles.

Strip shingles were first produced in the 1920’s. Before this, asphalt shingles were actually produced as single shingle units, about a foot wide.

Architectural Shingles

Architectural shingles are laminated shingles. They are called “architectural shingles” because the top layer of the shingle can be used to give the shingle desirable aesthetic or “architectural” effects.

Cut-outs and overlaps in the top layer of the shingle can give the shingle a “profile” that makes the shingle look thicker and more textured, with high definition and sharp shadow lines.

The terms “architectural shingles”, “dimensional shingles”, and “laminated shingles” are used interchangeably.

Dimensional Shingles

Basic dimensional shingles are generally the mid-tier shingle lines. Dimensional shingles are the most popular type of roofing shingles installed in North America today.

Dimensional shingles are laminated shingles: they are manufactured as a double-layered (and very rarely triple-layered) product. The multiple layers in the shingle give the installed shingles a multi-dimensional appearance, implying sturdiness and quality.

Dimensional shingles are generally thicker, heavier, and longer-lasting than strip shingles, with better warranties.

The terms “dimensional shingles”, “architectural shingles”, and “laminated shingles” are used interchangeably.

Luxury Shingles

These are the best roof shingles for both performance and appearance. Luxury shingles are the top-of-the-line shingles from most manufacturers today.

Luxury shingles are the thickest, highest-quality dimensional, architectural shingles.

The term “luxury shingles” is used interchangeably with “premium shingles”. Luxury shingles and premium shingles are the same thing.

Premium Shingles

Premium shingles are the top-tier shingles. Premium shingles are the thickest, highest-quality laminated or architectural shingles.

They are often designed to mimic other, more expensive roofing materials such as natural slate or cedar shake. This heightened curb appeal makes them stand out from other asphalt shingles.

Most premium shingles also have a high impact-resistance rating. Premium shingles typically cost the most, last the longest, and have the best warranties.

AR Shingles

“AR” stands for “algae-resistant”. Several manufacturers add the letters “AR” after the name of some of their the shingle lines, like “Vista® AR” by Malarkey.

“AR” means that the shingles are manufactured using algae-resistant granules. This helps prevent the unattractive black streaks that form on some roofs due to algae growth.

If the shingles have “Scotchgard™” after the name, it also means they are algae-resistant and use the trademarked Scotchgard granules from the 3M corporation.

IR Shingles

“IR” stands for “impact-resistant”. When you see “IR” after the name of a line of shingles, it generally means that the shingles are UL-certified for Class 4 impact resistance, the highest impact resistance rating.

Most (but not all!) IR shingles are made with polymer-modified asphalt.
