Maryland weather is a four season stress test. Humid summers, freeze-thaw cycles in February, the occasional July hailstorm and the Nor’easters that roll up from the Chesapeake. When homeowners in Frederick or Howard County ask us what roof to put over their head, the conversation almost always comes down to two options: asphalt shingles or standing seam metal. Both work. They just work very differently for your wallet and your timeline.
Here is how they actually stack up for a Maryland home.
Asphalt is the budget winner, and it is not close. Architectural asphalt shingles installed on a typical Maryland home run between 3 and 7 dollars per square foot, including tear off and disposal. That puts most 2,000 square foot homes in the 10,000 to 16,000 dollar range.
Standing seam metal is a bigger check. Installed cost ranges from 7 to 14 dollars per square foot depending on the gauge of the steel, the panel profile and whether you go with a Kynar finish. The same 2,000 square foot home lands between 18,000 and 30,000 dollars. Aluminum and copper push the high end even higher.
If the only thing you care about is the check you write this year, asphalt wins. If you are looking at the check over 30 years, the math gets more interesting.
A quality architectural asphalt shingle in Maryland lasts 20 to 30 years. The humidity and summer heat shave a few years off the manufacturer rating. Three tab shingles, which we do not recommend anymore, barely make it to 18 years around here.
Standing seam metal lasts 40 to 70 years. The paint finish is usually the first thing to age out, but the underlying steel keeps working. Most Kynar 500 finishes carry a 30 to 40 year warranty against chalking and fading. The substrate outlasts most mortgages.
For homeowners planning to stay in the house for 15 years or less, asphalt makes financial sense. For empty nesters or multi-generational homes, metal is often the last roof you will ever buy.
Maryland throws a lot at a roof. Both materials handle wind well when installed correctly. Asphalt shingles rated for 110 to 130 mph winds are standard now. Metal panels are typically rated for 120 to 140 mph and perform better in the uplift tests that matter during our summer thunderstorms.
Hail is where the gap shows up. A one inch hailstone can bruise an asphalt shingle, knocking granules loose and shortening the roof life. The same hailstone on a 24 gauge metal panel leaves a cosmetic dent and nothing more. Maryland is not in the worst hail belt, but Frederick and Washington counties see hail events almost every year.
Snow and ice slide off metal faster, which reduces ice dam risk. Asphalt with proper attic ventilation and ice and water shield at the eaves also handles our winters fine. The difference matters most on low pitch sections.
This is the question every homeowner asks about metal. Will it sound like a drum during a rainstorm?
Short answer: no, not if it is installed over a solid deck with proper underlayment. The myth comes from old barn roofs where corrugated metal was screwed straight to purlins with air gaps underneath. A modern standing seam roof with a synthetic underlayment over plywood is only a few decibels louder than asphalt during heavy rain. Most homeowners tell us they barely notice.
Asphalt weighs about 2.5 to 4 pounds per square foot. Metal is lighter, typically 1 to 1.5 pounds per square foot. If your roof deck is old or your home had multiple layers of shingles removed, the lighter load from metal can be a real plus. We rarely have to reinforce framing for a metal installation.
This is where metal often surprises people. Most Maryland insurers offer a 5 to 15 percent discount on the homeowners premium for an impact rated roof, which includes standing seam metal and Class 4 asphalt shingles. Travelers, State Farm and Allstate all have versions of this discount active in Maryland.
The other insurance angle is the age cutoff. Some carriers are now declining to renew policies on asphalt roofs over 15 years old. A metal roof sidesteps that problem entirely for decades.
For most Maryland homes on a normal budget, quality architectural asphalt shingles are the right answer. They perform well, they look good, and the upfront cost fits into a typical home improvement budget or a financed project.
Metal makes the most sense in three situations. First, if you plan to own the home for 20 plus years and want to buy exactly one more roof. Second, if you live near the Chesapeake or the Eastern Shore where salt air and humidity punish asphalt. Third, if you have a low pitch or a complicated roof where the long seams of a standing seam system shed water more reliably than shingles.
There is no universal right answer. The right answer depends on your roof pitch, your plans, your budget and how much you care about what the roof looks like from the curb.
We install both asphalt and metal roofs across Frederick, Montgomery and Howard counties. If you want real numbers for your specific home, not ballpark ranges, we can walk the roof and put two line item estimates in front of you the same week.
