🏠Understanding Flat Roofing: Residential and Commercial Options with Warner Roofing
Flat roofing isn’t just for commercial buildings anymore. While you’ll often see it on schools, warehouses, and office complexes, flat roofs are becoming increasingly common on residential homes throughout Northern Illinois and Southern Wisconsin — especially in areas like Rockford, Pecatonica, Roscoe, and Loves Park.
Whether you own a business or a home, Warner Roofing & Restoration has the expertise to handle every flat roofing system with precision and care.
🏡 Residential Flat Roofing Options
Flat or low-slope roofs can be found on a wide variety of home styles. Here are the most common types we see:
1. Modified Bitumen (Mod Bit)
A durable asphalt-based system ideal for smaller flat roof areas such as porches, garages, and additions. It’s flexible and performs well in Midwest climates.
2. EPDM (Rubber Roofing)
A long-lasting, single-ply rubber membrane that’s perfect for modern homes, garages, or flat roof extensions. EPDM is known for its resistance to UV damage and extreme temperatures.
3. TPO (Thermoplastic Polyolefin)
A reflective, energy-efficient material that helps lower cooling costs. It’s a popular option for newer flat-roof homes and energy-conscious homeowners.
4. PVC Roofing
Highly durable and resistant to chemicals and water, PVC roofs are great for homes with heavy rainfall or rooftop decks.
5. Built-Up Roofing (BUR)
A traditional hot-tar and gravel system, often used on older homes, providing excellent waterproofing when maintained properly.
