why flat roofing is a practical choice in Joliet IL
Ideal for Low-Slope and Modern Structures
Flat roofing is the go-to option for structures with a slope of 10 degrees or less. It's commonly used in commercial buildings, apartment complexes, garages, sheds, and increasingly, modern home designs that’s becoming more popular across Joliet IL developing neighborhoods.
Cost-Effective Installation and Repairs
Flat roofing systems are often less expensive to install compared to pitched roofing due to reduced materials, faster labor, and simplified structural design. Repair and maintenance costs are also typically lower, especially for single-ply membrane systems like TPO and EPDM, which allow for easy patching and resealing.
Energy Efficiency and Reflectivity
Many flat roofing materials are designed with reflective, energy-efficient surfaces that help keep indoor temperatures stable. White TPO and other light-colored membranes reflect sunlight, reducing heat absorption and helping to lower cooling costs during Joliet IL hot summers.
Space Utilization
A flat roof can serve as more than just a cover—it can be converted into a usable space. Depending on your structure and code compliance, flat roofs can be used for rooftop gardens, patios, equipment staging, or additional storage. This adds functional value to your property without taking up extra square footage on the ground.

TPO roofing is a single-ply membrane that offers excellent UV resistance, energy efficiency, and flexibility. It's heat-welded at the seams for superior waterproofing and is one of the most popular flat roofing materials in Spring Hill due to its cost-to-performance ratio.
TPO (Thermoplastic Polyolefin)
EPDM is a durable synthetic rubber roofing membrane known for its strength, weather resistance, and longevity. It performs well in both hot and cold climates and is particularly effective at resisting ozone, hail, and UV degradation.
EPDM (Ethylene Propylene Diene Monomer)
This asphalt-based system is commonly used in both residential and commercial low-slope roofing. It consists of multiple plies, often with a granulated surface, and can be torch-applied, cold-applied, or self-adhered. It’s ideal for roofs that need added puncture resistance and durability.
Modified Bitumen
BUR is a traditional flat roofing system that uses alternating layers of bitumen and reinforcing fabric, topped with gravel or a reflective coating. Though heavier than modern membranes, it’s extremely robust and offers excellent protection against heavy foot traffic and extreme weather.

Frequently Asked Questions About commercial flat Roofing at truroof Joliet IL roofers
How long does a flat roof last?
The average flat roof lasts between 15 to 30 years depending on the system used and how well it's maintained. TPO and EPDM typically last 20–25 years with proper care. Modified bitumen and BUR systems can reach 30 years or more under ideal conditions. TruRoof Joliet IL only installs roofing systems from trusted manufacturers and adheres to strict Joliet IL building codes for long-term performance.
Is flat roofing waterproof?
Yes. Properly installed flat roofs are completely waterproof. We use heat-welded or fully adhered systems with reinforced seams to prevent leaks.
How do you prevent ponding on a flat roof?
We ensure proper drainage by installing internal drains, scuppers, or tapered insulation systems to direct water flow and eliminate pooling.
Does a flat roof increase cooling costs?
No. When installed with energy-efficient membranes like TPO, flat roofs can help reduce cooling costs by reflecting heat away from your building.
Can flat roofs support solar panels?
Yes. Flat roofs are ideal for solar installations since panels can be tilted for maximum sun exposure. We ensure your structure can handle the added load.
How often should flat roofs be inspected?
Twice a year—typically in the spring and fall—and after any major storm. Preventive maintenance is key to extending the life of your flat roof.
Are flat roofs more likely to leak?
Not if installed correctly. Modern flat roofing systems are designed to resist leaks with reinforced seams and proper slope. Most leaks occur due to poor installation or neglect.
What’s the best material for flat roofing in Joliet IL?
TPO and modified bitumen are top choices for Joliet IL heat, humidity, and storms. Both offer flexibility, UV resistance, and excellent waterproofing.
Can you install a new flat roof over an old one?
Yes, in some cases. A roof overlay is possible if the underlying structure is sound and only one previous roof layer exists. We’ll inspect and advise accordingly.
How much does a flat roof replacement cost?
In Joliet IL, flat roof replacement typically ranges from $8 to $15 per square foot, depending on materials, access, and prep work. We provide free, detailed estimates.
Do flat roofs qualify for insurance discounts?
Possibly. Some flat roofing systems with high wind uplift resistance or reflective properties may qualify for insurance or energy rebates. Check with your provider.
