Currently, the asphalt shingle roof is used the most on homes in Maryland, but that doesn’t mean homeowners always know why they’re so common. With so many names floating around, like architectural asphalt, three-tab, composition, and dimensional, it can feel like you’re trying to learn a new language before you even choose a roof. And when every brand claims to be “the best,” figuring out what actually matters gets tricky fast.
This information guide breaks everything down using what we’ve learned from installing thousands of asphalt shingle roofs across Maryland. You’ll get clear explanations of what asphalt shingles are, how they hold up in Maryland’s weather, why asphalt shingle roofs stay so popular, and what to know about warranties before you choose a shingle. Once the basics make sense, comparing shingle options becomes much simpler and far less boring.
Quick Facts About Asphalt Roofing Shingles
Here is the key information most homeowners want before comparing asphalt shingles. It covers roof performance, roofing basics, and the warranty rights that matter after installation.
- Shingles are the most common roof material in the US.
- Lifespan often ranges from 20 to 30+ years
- Installed cost usually ranges between mid-tier and budget-friendly levels
- Works well for a sloped roof in four-season climates
- Available in three-tab, architectural, and luxury styles
- Easy to repair when damaged, especially compared to other roofing material
- Many asphalt shingle color and design options are available
What Are Asphalt Shingles?
Asphalt shingles are a layered roofing material designed to protect your home from wind, rain, and changing temperatures. Each asphalt shingle starts with a fiberglass mat that gets coated in asphalt, then topped with colored granules. The granules are what you see from the ground, but the asphalt layer underneath is what gives the shingle its waterproofing strength. Many modern asphalt shingles also include algae-resistant granules, which help prevent the dark streaks commonly seen on roofing in humid areas like Maryland.
There are several types of asphalt shingles, and the names often confuse homeowners.
- Three-tab asphalt shingles are the basic, budget-friendly option with a flat look.
- Architectural shingles are also called dimensional shingles because they have multiple layers that create depth and shadow lines.
- Luxury shingles are the premium version, built thicker and designed to mimic slate or wood.
All of these fall under the broader category of asphalt shingles, because the asphalt layer is what makes the system durable and weather resistant.
Benefits of Asphalt Shingles
Asphalt shingles offer strong value for Maryland homeowners. They balance cost, durability, and appearance while performing well in all seasons.
Cost-Effective and Durable
Asphalt is a proven waterproofing material. Asphalt shingles handle thunderstorms, winter storms, and daily weather changes without trouble. Their layered design provides solid wind resistance. Even with their affordable price, asphalt shingles remain one of the toughest residential roofing material products available.
Multiple Designs and Colors
Asphalt shingles come in many colors, shapes, and styles. Some varieties mimic slate or wood for a more custom look. This range of options helps homeowners match siding, trim, and the overall style of their home. It also makes asphalt shingles a reliable choice for improving curb appeal.
Simple Installation and Maintenance
Asphalt shingles are easy to repair and maintain. Small roof repairs do not require specialized tools. Full installations should be handled by trained roofers, but homeowners appreciate the lower repair costs throughout the roof’s lifespan.
Asphalt Shingle Types Compared
Three Tab
- Cost: Lowest cost
- Durability: Thinner design
- Lifespan: 20-25 years
- Best Use Case: Budget roofing or simple structures
Architectural
- Cost: Mid to high
- Durability: Strong durability
- Lifespan: 30 to 50 years
- Best Use Case: Most Maryland homes
Luxury
- Cost: Highest cost
- Durability: Strong durability
- Lifespan: 30 to 50 years
- Best Use Case: High curb appeal or premium homes
Every manufacturer has its own version of these three types of asphalt shingles, each with different features, color, and warranty. Brands like CertainTeed and GAF offer unique blends of strength, weather protection, and visual design, so comparing the specs and warranty coverage is just as important as comparing the price.
How Long Does a Shingle Roof Last in Maryland?
Most asphalt shingles in Maryland last around 20 to 30 years or more, but the true lifespan depends on three key factors: installation quality, ventilation, and roof maintenance. It’s common to see a 25-year asphalt shingle need major repairs or full replacement around year 20, and a 50-year shingle fall short around year 30. The final lifespan always comes down to how well the roof was installed, how well the attic breathes, and how consistently the roof is maintained.
Initial Installation
A roof that is installed poorly from the start will age faster. Issues like exposed nails, improper flashing, and bad drainage in the valleys create ongoing problems that stack up over time and lead to early replacement.
Attic Ventilation
Ventilation is another major factor that many roofing contractors overlook. When the attic cannot release heat properly, temperatures climb, which causes asphalt shingles to blister and break down faster. Poor airflow shortens the life of even the best architectural shingles.
Maintenance
Maintenance also plays a major role. A roof that receives routine care often outlasts its expected lifespan. We have seen a 25-year asphalt shingle last nearly 28 years simply because the homeowner kept up with small repairs like replacing minor flashing pieces and securing loose tabs. Proper roof upkeep can add years to your roof and delay the need for a full roof replacement.
Understanding Warranties
These asphalt shingle roof warranty parameters can be confusing because the advertised lifespan of an asphalt shingle does not always match the actual coverage. Many roof shingles are marketed as 25-year or 50-year products. That number is only backed by a guarantee when the roof is installed by a certified contractor that’s approved by the manufacturer. Without a certified contractor, the warranty coverage from the manufacturer drops to basic coverage that lasts far fewer years.
Three-tab shingles: 25-year warranty
Architectural shingles: 30-50 years depending on the line of shingles
Luxury: 50-year warranty
Different components of the roof also carry different limited warranty qualifications. Some manufacturers, like GAF Timberline, advertise a 50-year asphalt shingle warranty but only cover the ridge caps for about 15 years. Ridge caps face the highest wind pressure, so their coverage period is shorter. This difference surprises many homeowners. A full roofing system warranty requires approved material, certified installation, and proper ventilation.
When choosing a roof warranty, keep in mind that the highest-tier options, such as the enhanced system warranty like the Platinum Protection Warranty from Owens, include both material and labor coverage. This means that if your contractor ever goes out of business, the rights will still be honored by the manufacturer, and they will pay the labor costs for the repair. This level of protection is the safest option for long-term peace of mind.
Cost of Asphalt Shingles
The cost of installing new shingles on your roof depends on several factors, but most Maryland homes fall within a predictable price range. A roof with asphalt shingles remains one of the most affordable and reliable options, yet the final cost of a roof can shift based on the type of shingle you choose and the condition of your existing roofing material.
Shingle roofing projects are priced by the “square,” which equals 100 square feet. In Maryland, the average cost of a roofing square typically ranges from $350 to $700 per square, depending on the shingle type, installation requirements, and the amount of prep work needed. Architectural shingles fall in the middle of that range, while luxury asphalt shingles sit at the higher end.
These are the main factors that influence your total roof cost:
- Roof size: A larger roof requires more material and more time to install.
- Asphalt shingle type: Three-tab, architectural, and luxury, each coming with different price points and performance levels.
- Existing roof layers: Removing old layers of an asphalt shingle roof adds labor and disposal costs.
- Roof pitch and complexity: Steeper or cut-up roofing takes longer to install and requires additional safety steps.
- Flashing needs: Chimneys, skylights, and walls that intersect with the roof may require new flashing for proper waterproofing.
- Ventilation improvements: Upgrading ridge vents or adding soffit vents helps your roof last longer and may be required for warranty coverage.
- Damaged roof decking: Any soft or rotted wood underneath the roof must be replaced to ensure a stable installation.
No two homes are exactly alike, which is why ballpark price ranges only go so far. A simple roof with one story and a mild pitch will cost less than a steep multi-level home with several penetrations and valleys.

Compare Shingles to Other Roofing Materials
Metal Roof vs. Shingles
Metal roofing delivers stronger long-term performance than asphalt shingles, especially in areas with high winds, heavy rain, or major temperature changes. A well-installed metal roof system can last 40 to 70 years. While most shingle roofing lasts 20 to 30 years depending on ventilation, installation, and routine care.
A metal roof also reflects more heat, which can help lower cooling costs in hot summers. It does not crack, curl, or lose granules over time. Shingles still remain the more affordable roofing option and are easier to repair when small issues come up.
Homeowners often choose the asphalt shingle roof for their price and wide range of shingle colors and styles. Metal roofing is usually selected for long-term roof durability, lower maintenance, and better performance in tough weather.
Class 3 vs. Class 4 Shingles
Class 3 and Class 4 roof shingles are impact-rated products built to handle hail. The main difference in asphalt shingle class is strength. Class 3 roof shingles hold up to a 1.75-inch steel ball. Class 4 shingles pass a tougher test using a 2-inch steel ball dropped from a higher point. This higher rating gives Class 4 roof shingles better protection against cracking, bruising, and granule loss during storms. Many insurance companies offer discounts for a Class 4 asphalt shingle roof because they lower the risk of future claims. For homes in storm-heavy regions, Class 4 roof shingles will often deliver the best long-term value.
Solar Shingles vs. Solar Panels
Solar shingles blend into the roof and act as both roofing material and solar power generators. These shingles offer a cleaner appearance and eliminate the need for large racks or panels mounted above your roof. However, solar shingles are generally more expensive and less efficient per square foot than traditional solar panels. Solar panels, when placed on the roof, generate more energy, can be angled for better performance, and are easier to service or replace. Solar shingles are a better fit for homeowners prioritizing aesthetics or building a new roof, while panels remain the strongest option for maximizing energy production and reducing electricity costs.
Composite Shingles vs. Asphalt Shingles
Many homeowners get confused by the terms “composite roof shingles,” “composition roof shingles,” and “asphalt shingles,” because the words are often used interchangeably. Technically, all modern asphalt shingles are composition roof shingles. They are built from multiple layers: a fiberglass mat, asphalt, and protective mineral granules.
The confusion comes from the fact that “composite roof shingles” can also refer to high-end synthetic roofing made from engineered polymers and recycled material. These synthetic shingles are designed to mimic slate, cedar, or shake and offer greater impact, fire, and UV resistance than standard asphalt shingles.
So while both materials are “composite” in the literal sense, traditional asphalt shingles remain the economical, widely used choice for Maryland homeowners, and synthetic composite asphalt shingles sit in a separate premium category focused on appearance and long-term performance.
