Pros and cons of asphalt shingles are one of the most researched topics among homeowners and contractors alike and with good reason. According to IBISWorld, over 70% of residential roofs in the U.S. are covered with asphalt shingles, making them the undisputed leader in American roofing materials.

If you’ve ever wondered whether asphalt shingles are the right fit for your home or if you’re questioning their longevity, appearance, or value, you’re not alone. Thousands of homeowners are asking the same thing. And with so many options on the market, it’s easy to get lost in the noise.

So, in this expert-backed guide, we’ll break down the pros and cons of asphalt shingles in a clear, objective and practical way. Whether you’re installing a roof for the first time or considering a replacement, this review will help you make an informed decision based on real insights, not just marketing hype.

Don’t miss this opportunity to learn what thousands of property owners wish they knew before choosing their roof. Let’s dive into the facts that matter most.

What Are Asphalt Shingles and How Do They Work?

Asphalt shingles are roofing materials made with a fiberglass or organic base, coated with asphalt and topped with ceramic granules. They protect homes from rain, wind, sun and snow while offering a cost-effective way to cover a roof.

Now, let’s break that down. Imagine your roof like a layered sandwich. The asphalt shingle sits at the top, acting like a crunchy toast that shields everything underneath. However, this toast doesn’t get soggy in the rain. That’s because each shingle is built in layers:

• Base layer: A fiberglass mat (or old-school cellulose) gives its structure.
• Middle layer: Asphalt adds waterproofing and weather resistance.
• Top layer: Ceramic granules reflect UV rays and give color, texture and extra protection.

These shingles overlap like fish scales, creating a tight barrier that channels water down the slope and into the gutters, instead of inside your living room.

How they’re installed (in plain words)

Roofers install them from bottom to top, row by row. Each new row overlaps the one below it. This overlap creates what we call a water-shedding system. Nails hold the shingles in place, but placement matters. If the roofer gets sloppy, it’s game over. Leaks, shingle blow-offs and headaches follow.

So, this is important: You should never use shortcuts like glue or staples and for temporary tarp fixes? We’ll talk more about that later, but yeah, hammering through the shingles is not the move.

Protect Preserve Roofing insight: Asphalt shingles have been around for over 100 years and a standard asphalt shingle roof typically lasts 15 to 30 years, depending on quality and climate. They are cheap, easy to install and come in a wide range of colors and styles.

Why Are Asphalt Shingles So Popular in Roofing?

If you look around most American neighborhoods, chances are you’ll see the same thing: asphalt shingles on almost every roof. This isn’t a coincidence. It’s a combination of price, practicality and let’s be honest, habit. Let’s be real :

• Affordable: Asphalt shingles are one of the cheapest roofing options available. Materials cost less and installation is faster, which keeps labor costs down. On average, installing asphalt shingles costs 30% to 50% less than metal or tile roofing.
• Easy to install and replace: Roofers love them because they don’t cause headaches. Shingles are lightweight, flexible, and require fewer tools to install. That means less time on your roof and less money coming out of your wallet.
• Look good (and you get options): Today’s asphalt shingles come in all sorts of colors, textures and styles (3-tab, architectural, luxury). Whether you want a clean, modern look or something that mimics wood or slate, there’s probably a shingle for that.
• Handle most weather like a champ: From rain to snow, asphalt shingles hold their own. Are they perfect in extreme heat or high-wind areas? Not always. But for most climates in the U.S., they check all the boxes.
• Work well with insurance and maintenance plans: Insurers are familiar with asphalt shingles. That can make claims and inspections simpler. Repairs are quick and don’t require calling in a rescue team. And let’s be honest, no one wants to fight the insurance company and the weather in the same week.

Quick reminder from Protect Preserve Roofing: They may not be flashy, but asphalt shingles are like that one friend who always shows up on time, brings beer to the barbecue and never asks for much. Dependable, cheap and always ready to cover your back… literally.

Pros of Asphalt Shingles

Asphalt shingles are popular for a reason, actually, for several reasons. To make things easier, here’s a no-nonsense comparison table that shows why many homeowners still prefer asphalt shingles over other roofing options:

Important reminder from Protect Preserve Roofing: Even though asphalt shingles bring a lot to the table, they aren’t invincible. They’re strong in practicality, but you’ll want to see the other side of the story before you decide.

Cons of Asphalt Shingles

Asphalt shingles are budget-friendly and easy to work with. However, they’re not bulletproof. Here’s a no-fluff comparison table showing the main drawbacks of asphalt shingles and what they actually mean for your home:

Pro tip from Protect Preserve Roofing: If you’re in a mild climate and you want a roof that looks decent, costs less and gets installed quickly? Asphalt shingles are still a great option. Therefore, if you’re chasing long-term durability, low maintenance and a higher-end look, it might be worth weighing other options.

Pros and Cons of Asphalt Shingles: Should You Paint?

While painting shingles is possible, it’s not always smart. There are real trade-offs that most people don’t know until it’s too late. So, before you reach for that roller, take a look at this breakdown:

Important notes before you paint

• Use 100% acrylic latex paint, designed for roofs. No wall paint. No shortcuts.
• You’ll need to pressure wash and fully dry the roof before painting. Any trapped dirt or moisture? Say hello to mold.
• If your roof is already nearing the end of its lifespan, painting it is like waxing a car that’s falling apart. Looks shiny for a week, then regrets come knocking.

Protect Preserve Roofing insight: In most situations, painting is a temporary band-aid, not a long-term solution. You’ll spend less (and sleep better) by investing in proper repairs or replacements when the time is right.

Second Layer Is a Smart Move: Pros and Cons of Asphalt Shingles

Let’s pause and look at what you’re really getting into, because doubling up on shingles isn’t always doubling the protection:

When is a second layer acceptable?

Adding a second layer is only recommended in specific conditions, like:

• The first layer is still flat and in decent shape (no curling or rot).
• The roof structure is strong and approved to handle extra weight.
• You’re not planning to stay in the house long-term.
• The local building code allows it.

Even then, think of it as buying time, not investing in the future. You’re postponing a full replacement, not avoiding it.

When you should not do it

• The first layer is damaged, soft, or showing signs of water infiltration.
• Your home is over 30 years old.
• The roof has a complex shape or multiple valleys/slopes.
• You’re concerned about insurance issues or resale value.

And here’s a big one: If you live in an area with high heat or heavy rain, that second layer can trap heat and moisture, which leads to more problems than it solves.

Bottom line: Tearing off and starting fresh gives better results… period. You’ll have a longer-lasting roof, a valid warranty, fewer maintenance headaches and peace of mind during the next storm.

Pros and Cons of Asphalt Shingles: Reroofing

Reroofing over existing asphalt shingles might sound like a shortcut to save money and time. However, roofing isn’t like stacking pancakes. Just because you can pile it on, doesn’t mean you should.

Reroofing over shingles means you install new shingles directly over the existing ones, without removing the old layer. This is called an overlay, but it isn’t always a smart move. Let’s see:

Best practices if you do reroof over existing shingles

Sometimes, reroofing is acceptable, if you follow strict rules:

• Only one layer exists underneath (most codes allow a max of 2 total layers).
• No soft spots, leaks, or decking damage on the current roof.
• The roof is structurally sound to handle the weight.
• You use architectural shingles, which are thicker and hide minor imperfections better.
• Local building codes explicitly allow it.

If any of the above are missing do not overlay. You’ll just be covering problems that will come back with vengeance.

Quick reminder: At Protect Preserve Roofing, we’ve seen both good and bad overlay jobs. And here’s the truth: “Reroofing over an old roof is like painting over rust. It hides the issue but never solves it.” Overlaying should never be a default option. It’s a calculated risk, not a long-term solution.

What Happens If You Don’t Tear Off Asphalt Shingles?

A lot of homeowners are tempted by the lower price and faster timeline. Therefore, not tearing off the old shingles comes with hidden costs and we’re not just talking about money. Let’s break down what really happens – the pros and cons of asphalt shingles – when you take the shortcut:

What about insurance?

Here’s the cold truth: Most insurers will not cover roof damage if it’s linked to improper installation or neglected tear-off. And if your roof leaks due to trapped moisture from the old layer, your insurance may deny the claim entirely.

In short: skipping the tear-off could cost you a lot more than just the roof.

When tear-off is the right call?

In most cases, tearing off the old shingles is the smartest and safest move, especially if:

• The roof is over 15–20 years old.
• You’ve had leaks or moisture issues.
• You want the warranty to actually mean something.
• You’re planning to sell your home in the next 5–10 years.

Plus, a full tear-off lets professionals inspect, repair and reinforce every part of your roofing system, not just cover it up.

Bottom line: At Protect Preserve Roofing, we’ve seen it all. One homeowner skipped the tear-off to save $1,500. Three months later, a minor leak turned into a full interior ceiling collapse and the insurance? They walked away. Lesson learned: always fix what’s underneath before you cover it up.

Asphalt Shingles vs. Other Roofing Materials

Let’s break down how asphalt shingles compare to other popular options like metal, tile and wood, all in one clean table:

Pro tip from Protect Preserve Roofing: For most homeowners, asphalt shingles are the easiest starting point. However, if you’re building your forever home and have the budget, metal or tile might be worth the investment.

Pros and Cons of Asphalt Shingles Based on Climate and Budget

Let’s break it down by climate and budget, because that’s where most people start when choosing a roof:

When you might want to skip asphalt shingles

• You’re building your “forever home” and want something ultra-durable.
• You live in a coastal area with hurricanes or constant salt air.
• You hate maintenance and want a roof you’ll never have to think about again.

In those cases, materials like metal or tile might be better long-term play (even if they hit harder on the wallet upfront).

Bottom line: Asphalt shingles are versatile, cost-effective and practical, but they aren’t perfect for everyone or every region. That’s why at Protect Preserve Roofing, we always assess your local climate, goals for the home, budget and timeline (short-term vs. long-term).

Conclusion: The Pros and Cons of Asphalt Shingles

By now, you know the pros and cons of asphalt shingles, that shingles aren’t perfect, but they don’t pretend to be. They’re practical, affordable, easy to install and in the right conditions, they get the job done without draining your bank account.

Still, roofing isn’t one-size-fits-all. Your roof takes the hit from everything outside: rain, sun, hail, heat, wind. And that means what you choose today will protect your home (or not) for decades.

However, the success of your roof has more to do with the installer than the material. Cheap shingles installed wrong will fail and mid-range shingles installed right? They’ll surprise you.

That’s where we come in. At Protect Preserve Roofing, we don’t just “put a roof on your house”. We protect your home, preserve your investment and we do it with real expertise, care and respect for your time and money.
