Drive through Boone and McHenry counties and you'll see both: asphalt shingles on most houses, and metal on pole barns, machine sheds, garages and a growing number of homes. Both materials can do a good job in Northern Illinois weather. The right choice depends on the building, your budget, how long you plan to stay, and how you want it to look.
Asphalt shingles are the most common residential roofing material in the country for good reasons. The upfront cost is typically lower than metal, installation is familiar to most crews, repairs are straightforward, and there's a wide range of colors and styles, including architectural shingles with a dimensional look. For many homeowners who want a solid, good-looking roof at a reasonable price, shingles are the practical choice.
The tradeoff is lifespan and maintenance. Shingles wear gradually from sun, wind and freeze-thaw cycles, and a shingle roof is commonly expected to last roughly 20 to 30 years depending on the product and conditions. Strong winds can lift or tear them, and hail can bruise them. None of that makes shingles a bad choice — it just means you should plan for replacement at some point and keep an eye on the roof after major storms.
Metal roofing generally costs more to install, but a properly installed metal roof is commonly expected to last considerably longer than asphalt shingles. It sheds snow more readily, stands up well to wind when fastened correctly, and doesn't lose granules or curl with age. Many homeowners also like that it reflects more sunlight, which can help keep attics cooler in summer. On the downside, rain and hail can be louder on metal depending on the roof assembly, large hail can dent some panels, and repairs can be more specialized.
For pole barns, garages, sheds and other outbuildings, metal is often the natural fit. Exposed-fastener panels are economical, go up quickly over purlins, and cover large, simple roof areas well. That's why so many farm buildings in the area are metal. The details still matter: fasteners with proper washers, correct screw placement, trim at the ridges and eaves, and attention to condensation inside unheated or partly heated buildings all make a difference in how the roof performs over time.
On houses, standing-seam metal with concealed fasteners is a common choice for a cleaner look and fewer exposed screws to maintain, while exposed-fastener panels can work for some homes and additions at a lower cost. Snow sliding off a metal roof is something to plan for, especially over entrances, walkways and decks, where snow guards may be recommended. It's worth talking through where snow and water will land before choosing.
A few questions can narrow it down. How long do you plan to own the building? Is the upfront price or the long-term value more important to you? Does your neighborhood or HOA have rules about roofing materials? Is the building heated, and how is the attic or interior ventilated? There isn't one right answer for everyone, and a contractor who only pushes one option isn't giving you the full picture.
