Reasons Why Commercial Buildings in Chicago Prefer Flat Roofs
Flat roof systems look modern and stylish. However, this is not the main reason why more and more commercial structures in Chicago Areas are installing these. The actual benefits are much wider:
Ideal place for HVAC systems
Flat roofs create a special roof deck that companies can use for different purposes. Most often, a low slope allows the installation of HVAC units on the roof and keeps them safe from theft and damage. Additionally, local roofers near you can guarantee this system location simplifies air navigation and reduces overall costs.
Convenient drainage system
A building with a pitched roof drains water into gutters, which require regular cleaning. Flat roofs typically don’t have gutters. Instead, they use rainwater roll-off systems that direct water off the roof. These systems are much easier to maintain.
Energy-efficient roofing materials
Reflective materials on a flat roof can greatly reduce solar heat gain and reduce energy costs. Energy efficiency is among the most winning features of flat roof systems. They allow commercial spaces to remain comfortable without burdening cooling expenses.
Easier maintenance
Maintenance on flat roofs is simpler compared to pitched roofs. Without steep slopes, workers can easily access the roof just using stairs instead of ladders. This makes inspections and roofing repairs near me safer and faster.
Great space optimization
A flat roof offers the potential to create additional usable space. With proper reinforcement, flat roofs can accommodate storage, equipment, or even recreational features like sky gardens or pools. Pitched roofs do not have this advantage due to their slope.
Cost-effective construction
Flat roofs are generally less expensive to install than pitched roofs. This makes them an attractive option for large commercial buildings in IL. Additionally, flat roofs have a longer lifespan and require fewer repairs, which means long-term savings for businesses.
Types of Commercial Flat Roofs and Use Cases
Modern commercial flat roofing materials come in many options. They all differ, and before the installation, the property owner must know the pros and cons of each variant to determine the best one. Let’s explore what system is best choice for a commercial flat roof in Chicago.
The most common materials for commercial or industrial flat roofs in Chicago
Traditional flat roofs:
- Built-up roof (BUR). This long-term-use material is constructed from multiple layers of tar, felt, and gravel. BUR roofing system is quite heavy and provides stability and resistance to heavy foot traffic and UV radiation. However, it requires a reliable foundation due to its weight.
- Modified bitumen. Asphalt, together with added modifiers, is durable. This material is available in both torch-applied and self-adhering forms. It adapts well to temperature changes and provides good water resistance.
- Concrete. It does not need extra advertising – concrete is one of the oldest materials. It is strong, resistant to fire and long-lasting. These features make it suitable for large buildings, but it is more difficult and expensive to install and maintain.
- Metal roofing. Such roofs are usually made of aluminum or steel. They are lightweight, very durable, and have built-in reflective properties that help manage solar heat. Metal roofs last for years, but can be expensive and often require additional insulation for energy efficiency.
Single-ply roofing membranes:
- EPDM (Ethylene Propylene Diene Monomer). This synthetic rubber membrane roofing is flexible, UV- resistant and very popular for commercial flat roofs. EPDM is known for its ease of installation and low cost, but it does not save energy.
- TPO (Thermoplastic Polyolefin) and PVC (Polyvinyl Chloride). These materials are white and reflect sunlight very well. TPO comes with heat-welded seams for water resistance, and PVC roof withstands chemical influence. So, these are well-performing and environmentally-friendly roof options.
Eco-friendly choices:
- Green roofs. This roof has layers of soil and natural plants on a flat roof surface. They are rather complex to install as they need a reliable drainage system to correctly distribute water. At the same time, green roofs provide strong insulation and are highly sustainable. Consult roofing contractors near me who specialize in green roofing systems.
- Spray foam roofing (SPF). It is polyurethane foam that acts as an insulating layer over the roof. Its unique ability to seal every crack and crevice provides excellent water resistance and insulation. SPF roofs are durable and highly energy-efficient but require professional installation and UV protection.

Commercial Flat Roof Repairs – What to Expect in the Long Run?
Property owners should understand not only the benefits of flat roofs but their downsides. So, what issues can arise over time that require attention and repairs?
- Pooling water. Flat roofs are more prone to water accumulation as they have low-slope surfaces. If drainage systems do not work properly, water can pool and lead to leaks and roof damage. To avoid these issues, consider hiring a roofing company close to me for timely drainage maintenance and roof inspections.
- Leaks. This is a very common problem of flat roofs due to wear and tear, especially in older systems. Damage from the weather, poor installation, or punctures can cause water to go through and damage the interior of the building.
- Cracks and blisters. The materials on a flat roof can crack, blister, or shrink over time, mainly because of temperature fluctuations. These issues can create entry points for water, which can lead to more serious damage if overlooked.
- UV damage. Any roof can degrade under excessive sunlight and brittle or even crack. An additional UV-protective coating is always a wise solution.
- Certain materials, like EPDM, can shrink with age. This can lead to gaps that allow water to infiltrate the roof. Regular inspections are crucial for the early detection of these issues.
