When your roof starts showing its age, the big question comes up fast: Should you go with asphalt shingles or invest in a metal roof? Both choices have their upsides. Both come with trade-offs. The right answer depends on how long you’ll be in your home, how much you’re ready to spend up front, and what you expect your roof to deliver over the years.
At Allied Exteriors, we’ve worked on everything from straightforward shingle replacements that give homes a fresh look to heavy-duty metal roofs designed to last a lifetime. Here’s what you need to know as you weigh your options – a breakdown of the differences, the pros and cons, and straight answers to the questions homeowners ask us most.
Asphalt Shingles: Affordable and Familiar
Asphalt shingles are the workhorse of American roofing — and for good reason.
Pros:
- Lower upfront cost
- Quick installation
- Huge variety of colors and styles
Cons:
- Shorter lifespan (18–35 years)
- Less energy efficient than metal
- Fewer warranty options
Shingles come in several types: entry-level 3-tab, thicker architectural shingles, and premium options like the Owens Corning Duration line we install at Allied.
How long do asphalt shingles last?
Standard shingles will give you about 18 to 35 years, depending on product quality and local weather. Basic 3-tabs wear out faster, while premium architectural shingles can push closer to 30. Shingles are reliable and budget-friendly — but if you’re looking for something to last a lifetime, metal is the clear winner.
Metal Roofing: Built for the Long Haul
Metal roofing has become more popular with homeowners who want durability and efficiency.
Pros:
- Lasts 50–100 years
- Energy Star-certified finishes that reflect heat
- Hail resistance up to 2.5″
- Minimal maintenance
Cons:
- Higher upfront cost
- Requires experienced installation
Some homeowners still worry that metal is noisy or more likely to get hit by lightning. That’s a myth.
Do you need a lightning rod with a metal roof?
No. Metal doesn’t attract lightning. In fact, because it’s non-combustible, a metal roof can actually make your home safer in the rare event of a strike.
How long does a metal roof last?
A properly installed metal roof can last 50 to 100 years. Allied installs heavy-duty, rust-resistant Galvalume metal roofing panels that come with lifetime warranties. This isn’t a “20-year patch” — it’s a roof that can outlast your mortgage.
Can you put a metal roof over shingles?
Yes. In many cases, metal can go right over existing shingles. That saves money, avoids a messy tear-off, and speeds up the process. The only catch is your roof structure has to be sound — and that’s something Allied always checks before moving forward.
Cost Considerations
It’s natural to ask about cost first. A full roof replacement typically costs between $12,000 and $35,000, depending on the size of your home, the complexity of your roof, and the material you choose. Asphalt tends to cost less up front, while metal requires a bigger investment.
How much does a metal roof cost?
Metal roofs are priced higher than shingles at the start, but Allied keeps them accessible. With no-money-down financing, low- or no-interest options, and payments starting around $250 per month, a long-lasting roof is within reach for almost any homeowner.
If you’re planning to stay in your home for decades, metal usually delivers more value through durability, lower energy bills, and resale appeal. For those who need the lowest upfront investment, asphalt shingles are still the workhorse.
Installation and Maintenance
Here’s the good news: neither option takes as long as most people think.
- Shingles: We recommend a complete tear-off rather than layering. Too many layers can hide leaks and reduce ventilation. We use modern synthetic underlayment instead of outdated tar paper for durability.
- Metal: Can often go right over shingles, which cuts both time and cost.
Most Allied jobs are done in a single day. More complex projects may stretch to 2–2.5 days, but you won’t be living under tarps for weeks. From consultation to completion, expect the whole process to take up to four weeks.
Maintenance is where the materials diverge:
- Asphalt requires periodic checks for curling, granule loss, or storm damage.
- Metal needs very little upkeep if it’s installed with quality materials — and Allied’s steel panels are designed to last.
Looks and Curb Appeal
A roof has to do more than just protect your home — it has to look good doing it.
- Shingles: Classic, versatile, and available in dozens of colors. They blend seamlessly with nearly any architectural style.
- Metal: Sleek and modern. Allied’s Energy Star-certified finishes keep colors vibrant while reflecting UV rays to reduce heat absorption.
Both materials add value, but metal often delivers a bigger resale boost because buyers see it as a “forever roof.”
Making the Call
Still torn? Here’s the simplest way we frame it:
- Choose asphalt shingles if you want:
- Lower upfront cost
- Fast installation
- A traditional look with flexible color options
- Choose metal roofing if you want:
- A roof that lasts 50–100 years
- Energy efficiency and hail resistance
- Higher ROI and added resale value
Ask yourself: How long am I staying in this house? Do I want the lowest cost today, or the best value over time? Do I want less maintenance, or am I fine with occasional repairs?
