Roofing Supplies in Pontiac, IL

Asphalt shingles, architectural shingles, and metal roofing all perform well in Illinois’ mix of hot summers, heavy rain, and winter freeze-thaw cycles. Architectural (laminated) shingles are thicker and more durable than basic 3-tab shingles, making them a strong choice for wind and hail resistance. Metal panels shed snow easily and resist cracking, but they can cost more upfront. When choosing, look at impact ratings, wind ratings, and manufacturer warranties that specifically mention performance in harsh climates.

Asphalt shingles are usually more affordable initially, come in many styles and colors, and are easier for most contractors to install or repair. Metal roofing costs more up front but typically lasts longer, reflects more sunlight to help with cooling costs, and resists fire, rot, and insects. If you plan to stay in your home long term and want low maintenance, metal can be worth the investment. If budget and traditional appearance are priorities, high-quality architectural asphalt shingles are a solid choice.

In areas like Pontiac that see snow, it’s smart to pair your main roofing material with ice and water shield underlayment along eaves, valleys, and around penetrations to help prevent ice dam leaks. Architectural shingles or metal roofing with proper underlayment and flashing handle snow loads better than cheaper, thinner materials. Ridge vents combined with sufficient attic insulation and intake vents also help reduce ice dams. Look for products rated for cold climates and confirm they’re installed according to manufacturer specs for snow-prone regions.

Underlayment (felt or synthetic) is your secondary water barrier and should be installed smoothly and overlapped correctly, with ice and water shield in leak-prone areas. Drip edge should go along eaves and rakes to protect the roof deck edges and help guide water into gutters. Use compatible fasteners and flashing metals with your chosen roofing material to avoid corrosion. Always follow the manufacturer’s installation instructions closely, since improper accessory installation is a common cause of leaks.

Impact-resistant shingles are tested and rated (often Class 3 or Class 4) to better withstand hail and debris, which can reduce damage and may qualify for insurance discounts in some areas. Standard 3-tab shingles are cheaper but thinner and less durable, while architectural shingles offer a thicker profile, better wind ratings, and a longer expected lifespan. Some premium shingles also have enhanced algae resistance, reflective granules for energy efficiency, or extended warranties. When comparing, look at impact and wind ratings, algae-resistance features, and the length and terms of the manufacturer’s warranty.
