How Long Will a New Roof Last in Maryland?
At MARS Restoration, we’ve been working on Maryland roofs long enough to know one thing for sure—every homeowner wants their roof to last as long as possible. And why wouldn’t you? A new roof is a major investment, and no one wants to deal with unexpected repairs or replacements sooner than necessary. But the real question is: how long will a new roof last in Maryland?
The answer depends on several factors, including the type of roofing material, local weather conditions, and regular maintenance. Maryland’s climate brings a mix of hot summers, cold winters, heavy rain, and the occasional hurricane or tornado, all of which can impact a roof’s lifespan. At MARS Restoration, we believe that educating homeowners is the best way to take the stress out of roofing, so let’s break it down.
We’ll go over the different types of roofing materials, what affects their longevity, and how you can extend the life of your roof. Whether you’re planning for the future or wondering if your current roof is reaching the end of its life, this guide has the answers you need.

What Affects a Roof’s Lifespan in Maryland?
If every roof had an expiration date stamped on it, life would be much simpler. Unfortunately, that’s not the case. Several factors impact how long a roof will last in Maryland’s climate.
1. The Type of Roofing Material
Not all roofing materials are created equal. Some last twice as long as others, making the right choice essential for homeowners. Here’s a quick breakdown of how long different roofing materials typically last:
- Asphalt Shingles: 15–40 years (depending on type)
- Metal Roofing: 40–70 years
- Slate Roofing: 75–100+ years
- Cedar Shake Roofing: 30–50 years
- Flat Roofs (TPO, EPDM, PVC): 20–30 years
If durability is your priority, consider architectural asphalt shingles, metal roofing, or synthetic slate, which all hold up well against Maryland’s varying weather conditions.
2. Maryland’s Weather Conditions
From hot, humid summers to freezing winters, Maryland’s weather can be tough on a roof. Some of the biggest threats include:
- Heavy Rain and Storms: Maryland gets plenty of storms, especially in spring and summer, which can weaken shingles and lead to leaks.
- High Winds: Coastal storms and tornadoes can lift shingles or even cause structural damage.
- Hail Damage: Hailstorms, though less frequent, can crack or dent roofing materials.
- Snow and Ice: Cold winters bring snow, ice dams, and freeze-thaw cycles, which can cause roofing materials to expand and contract, leading to premature wear.
If your home is regularly exposed to these conditions, choosing impact-resistant shingles or metal roofing can help maximize your roof’s lifespan.
3. Installation Quality
A roof is only as good as the contractor who installs it. Poor installation leads to leaks, premature aging, and costly repairs. That’s why it’s critical to work with an experienced Maryland roofing company that understands local building codes and climate challenges.
At MARS Restoration, our expert crews ensure proper ventilation, shingle placement, and flashing installation, all of which are key to a long-lasting roof.
4. Regular Maintenance and Repairs
Would you drive a car for years without changing the oil? The same logic applies to your roof. Regular maintenance can add years—even decades—to its lifespan.
- Schedule yearly inspections to catch small issues before they become major problems.
- Keep gutters clear to prevent water from backing up and causing leaks.
- Trim overhanging branches that could scrape or fall onto the roof.
- Address missing shingles or minor leaks quickly to avoid bigger structural issues.

How Long Will Your Roof Last? A Breakdown by Material
Asphalt Shingles: The Most Common Choice
Asphalt shingles are affordable and widely used, but their lifespan varies based on the type:
- Three-tab Shingles: 15–20 years
- Architectural (Dimensional) Shingles: 35–40 years
- Impact-Resistant Shingles: 40+ years
If you’re looking for a longer-lasting and more storm-resistant option, architectural or impact-resistant shingles are the way to go.
Metal Roofing: Long-Lasting and Energy-Efficient
Metal roofing is becoming more popular due to its durability and energy efficiency. It reflects heat in the summer and withstands heavy storms better than shingles.
- Aluminum & Steel: 40–50 years
- Standing-Seam Metal: 50–70 years
- Copper Roofing: 75+ years
Metal roofing is ideal for homeowners who want a low-maintenance, long-term investment.
Slate Roofing: The 100-Year Roof
Slate is one of the most durable roofing materials available. While the upfront cost is high, it can last a lifetime or longer.
- Natural Slate: 75–100+ years
- Synthetic Slate (DaVinci): 50+ years
If you’re looking for timeless beauty and superior longevity, slate roofing is an excellent choice.
Cedar Shake Roofing: Classic and Durable
Cedar shakes and shingles provide a rustic look, but they require regular maintenance to prevent mold and insect damage.
- Cedar Shingles: 30–40 years
- Cedar Shakes: 40–50 years
If properly maintained, cedar roofing can last for decades while adding unique curb appeal to your home.
Flat Roofing: Common for Commercial Properties
Flat roofs are popular for commercial buildings and multi-family homes. Their lifespan depends on the material used:
- TPO & PVC Roofing: 20–30 years
- EPDM Roofing: 25–30 years
- Modified Bitumen & BUR Roofing: 20–30 years
Regular maintenance is essential to extend the life of a flat roof.
