Homeowners in Chicago often face a unique challenge – how to protect their flat roofs against local weather swings? The choice of materials is wide, but which one combines weather and water resistance and curb appeal? It’s rubber! Rubber roofing is long-lasting, affordable and energy efficient. Let’s explore why rubber roofing is one of the best solutions for Chicago low-sloped and flat roofs, the types of materials available, and what you need to know before the roof installment.

Rubber roofing is also known as elastomeric roofing. This flat roof material is made from flexible, synthetic rubber materials. It is not afraid of weather surprises, which is why it’s such a smart choice for homes and buildings in Chicago’s climate. Rubber outperforms asphalt shingles or built-up roofing as it is stronger and more durable.
There are three common types of rubber for flat roofs you can find on the market:
No matter the type, rubber roofing is reliable and remains in high demand for flat roofs across the Windy City.
Flat roof rubber | Thickness | Lifespan | Key Features | Cost | Maintenance |
EPDM (Ethylene Propylene Diene Monomer) | 45 mil, 60 mil, or 90 mil | 25-30 years | UV resistant, weather-resistant, flexible | Budget-friendly | Low; occasional cleaning and seam inspection |
TPO (Thermoplastic Polyolefin) | 45 mil, 60 mil, or 80 mil | 20-25 years | Reflective, heat-resistant, puncture-resistant | Mid-range | Low; routine inspections |
PVC (Polyvinyl Chloride) | 50 mil, 60 mil, or 80 mil | 25-35 years | Strong, chemical-resistant, weatherproof | Premium | Low; occasional inspections |
Your decision usually depends on a few things: your budget, the type of building, and how long you want the roof to last. For homes, EPDM is a good choice because it’s affordable and durable. TPO is also popular, especially if you are also looking to keep energy costs down. For commercial buildings, PVC rubber roofing is often the option because it’s tough and built to last. It is typically more expensive that other variants.
In Chicago, think about your roof’s shape, how much foot traffic it gets, and the weather conditions. It’s always a good idea to talk to an experienced roofing contractor – they can help you pick the best material and make sure you get the roof you need.

It is no coincidence that this rubber is one of the most commonly used materials for flat and low-sloped roofs. Rubber materials last longer and offer more benefits than traditional composite shingles. Here is why it is a popular choice.
Each type of rubber roofing (EPDM, TPO, PVC) has its own installation process. Here are the key things to know:
Aspect | EPDM | TPO | PVC |
Professional Installation | Expertise is needed to seal the seams and handle large sheets. | Seams are heat-welded and only experts can do it. | Heat welding or chemical welding is required for seams. |
Steps against water damage | Clean and prep the roof. Use adhesive or ballast. Seal seams with tape or liquid. | Clean and prepare the surface. Heat-weld seams. Install proper flashing. | Clean and prep the surface. Heat-weld or chemically weld seams. Add proper drainage. |
Installation differences | Large sheets mean fewer seams. Adhesive or ballast options. | Heat-welded seams for strength. Needs special equipment. | Heat-welded or chemically bonded seams. Strong but labor-heavy. |
Potential challenges on difficult structures | Adhesion issues on uneven surfaces. Difficult to install on roofs with many penetrations. | Requires a smooth surface for proper welding. Complex roofs may increase labor costs. | Heavy material, harder to handle on complex roofs. Requires precise welding for durability. |
Best for | Ideal for simple, flat roofs. Cost-effective for larger areas. | Best for energy-efficient needs. Suitable for roofs with moderate complexity. | Perfect for roofs that require high durability. Good for chemically exposed environments. |
What are common problems with rubber roofs? You can face seams coming apart, small holes from branches or people walking on them, water pools that stay for more than two days, pulled edges, cracks from too much sun, and leaves or dirt that block drains. If you see water stains on the ceiling inside your home or notice air bubbles under the roof surface, it’s a sign that something is really wrong and needs attention.
Some fixes you can manage yourself. For example, you can check the roof regularly for any damage and clear leaves and dirt from drains and gutters. Remove small branches, wipe off dirt, and inspect the integrity of all seams. This can prevent bigger issues later.
However, if you spot seams pulling apart, large rips, water that just won’t go away, or leaks that keep coming back, it’s time to invite a professional. Experts know how to fix rubber membranes, work on flashing, or improve drainage. If you try to tackle major repairs yourself, it can cancel your warranty or cause more damage.
The actual cost of rubber flat roof can vary significantly based on location (even within Chicago), the specific contractor, the complexity of the job, accessibility of the roof, and other factors. EPDM typically ranges from $4 to $8, TPO falls between $5 and $10, and PVC costs around $6 to $11. Within each category (EPDM, TPO, PVC), there are different grades and thicknesses of material. A thicker, higher-quality membrane will cost more than a thinner one. This per-square-foot cost is primarily for the membrane itself. You should also add tear-off and disposal of the old roof, underlayment, flashing, fasteners and adhesives and labor costs. Also, don’t forget about labor costs and waste disposal fees.
Installing a rubber roof is not a DIY job – it needs skills, experience, and knowledge of Chicago’s building codes. Professional roofers have certified expertise in EPDM installation. They will perform every installation step correctly and back up their work with long-term warranties.
