Asphalt and metal are the two roofs most Pennsylvania homeowners actually choose between. Slate and tile are beautiful and there is a place for flat systems, but on a typical home the real decision comes down to these two. Neither is best in the abstract. The right one depends on how long you plan to stay, your budget, the shape of your roof, and the look you want to live with. Here is how they really compare, feature by feature, so the choice is yours to make rather than the salesperson's to make for you.
Lifespan and durability
This is where metal pulls ahead most clearly. A quality architectural asphalt roof lasts about 25 to 30 years here when it is installed and ventilated correctly. A standing-seam metal roof commonly lasts 40 to 70 years, and it does it while shrugging off things that wear asphalt down. It does not lose granules, it will not curl or crack the way an aging shingle does, and it sheds snow rather than holding a heavy, wet load on the roof.
If your goal is to install a roof once and genuinely never think about it again, metal wins on longevity. If you want a proven, lower-cost roof that will still comfortably outlast your time in the house, asphalt does the job and does it well. Both are good roofs. They are simply built for different timelines.
Cost and the value question
Asphalt costs less up front and is the value choice for most homes, which is a big part of why it is the most common roof in the region by a wide margin. Metal costs more to install, but it lasts two to three times as long, so the cost per year of life can come out close or even ahead over the long haul. We keep the actual numbers on a separate page so this comparison stays about the decision rather than the dollars, but the short version is this: the sticker price favors asphalt, and the lifetime math narrows the gap more than most people expect.
The honest framing is not which is cheaper, it is which is cheaper for how long you will own the roof. Spread the cost over the years you will actually be in the house, and the winner can flip depending on that one number.
How each holds up to Pennsylvania weather
Our climate is hard on roofs in a specific way: repeated freeze and thaw, wet snow that sits, summer heat, and the occasional wind or hail event. Asphalt handles all of it well when it is installed with proper flashing and ventilation, though ice dams and trapped attic heat are the things that age it early. Metal tends to shed snow before it can build into a heavy load, and it is not bothered by the freeze-thaw cycling that works on other materials.
Hail is the one place where the answer is nuanced. Severe hail can dent a metal panel cosmetically even when it does no structural harm, while it bruises and strips an asphalt shingle in ways that shorten its life. Neither material is hail-proof. Both hold up to the wind and snow we actually get here when they are installed correctly.
Maintenance and repairs down the road
Asphalt is the easier and cheaper roof to repair. Shingles are widely stocked, most roofers can match and swap them, and a spot repair is straightforward. The trade-off is that you will likely be making those small repairs sooner and more often as the roof ages.
Metal asks for very little maintenance across its life, but when it does need work, the repair is more specialized. Panels, fasteners, and finishes have to be matched, and the fix is best left to someone who works with metal. For most owners that is a fair trade: less to think about for decades, in exchange for calling a specialist on the rare occasion something needs attention.
Looks and fit
Architectural asphalt suits almost any home and comes in a wide range of colors and profiles, including designer lines that add depth on larger, more visible roofs. It reads as traditional, it blends into most neighborhoods, and it gives you the most options for matching a specific style.
Metal gives a clean, modern line and a distinctive look, and it is a natural fit for farmhouses, barns, and outbuildings across our region, as well as contemporary homes that want that crisp profile. It also comes in shingle and shake-style panels for owners who want the longevity without the standing-seam look. On complex rooflines, both materials can work beautifully. What matters most there is not the material at all, it is the quality of the flashing at valleys, dormers, and transitions, which is where any roof either lasts or leaks.
So which should you choose
Lean asphalt if budget is the deciding factor, if you may move within 10 to 15 years, or if you want a traditional look and easy future repairs. Lean metal if this is a long-term or forever home, if you want to buy a roof once, or if the style of the house suits that clean profile and you value the low maintenance over the decades.
There is no wrong answer here, only a right answer for your house and your timeline. When we quote a roof, we lay both out honestly for your specific roof so you are choosing with real information instead of guessing which one is worth it.
Common questions
Is a metal roof louder in the rain?
Not meaningfully. With modern underlayment over solid decking, a properly installed metal roof is about as quiet inside as a shingle roof. The drumming sound people remember comes from metal laid over open framing on old barns, not from a residential install.
Which one adds more resale value?
Both a new asphalt or metal roof help resale, because buyers see a roof they will not have to replace soon. Metal can stand out in a listing for its lifespan, but a clean asphalt roof removes the same buyer objection at a lower cost. If you are selling within a few years, asphalt usually makes more financial sense.
Can I put a metal roof over my existing shingles?
Sometimes, but we generally price a full tear-off so we can inspect and repair the decking underneath. Going over old shingles can hide rot and complicate ventilation, and the roof is only as sound as what it is fastened to.
