Flat Roofing Services

Flat Roofing Experts in Chicagoland

Todco Roofing provides flat roofing services in Chicagoland for residential and commercial properties throughout the region. We bring the same level of precision and care to flat roofing as to our tile and slate work, because the building underneath deserves nothing less.

Flat roofing comes with its own set of challenges, materials, and failure points. A poorly installed or neglected flat roof does not just leak. It can cause widespread water damage to the structure beneath it before anyone realizes there’s a problem. That is why regular maintenance and timely repairs are the most important investment a property owner can make in a flat roofing system.

Flat Roofing Systems for Residential and Commercial Properties

Many properties throughout Chicagoland have flat or low-slope roof sections as part of their overall roofing system. Porches, additions, bay roofs, and commercial extensions often use flat roofing systems, and keeping those systems performing correctly is just as important as maintaining the primary roof.

We work on flat roofing systems across a wide range of property types, including:

  • Historic Residential Homes
  • Commercial and Mixed-Use Buildings
  • Churches and Institutional Structures
  • Flat Roof Additions and Extensions

Every flat roofing project we take on is approached with an understanding of the broader property it is part of, including how the flat roof connects to any adjacent tile, slate, or custom copper components.

Flat Roof Repair, Restoration, and Replacement

Whether the issue is a small leak, a failing membrane, or a system nearing the end of its useful life, we handle the full range of flat roofing work.

  • Flat Roof Repair: We diagnose and repair leaks, membrane failures, flashing separations, and drainage issues. Like any roofing repair, finding the actual source of the problem is the most important step.
  • Flat Roof Restoration & Coatings: When a flat roof membrane shows wear but the underlying structure remains sound, restoration and coatings are often the most cost-effective path forward, extending the life of an existing membrane without the cost of a full replacement. We assess what is there and recommend the right approach..
  • Flat Roof Replacement: When replacement is the right call, we handle the complete tear-off and installation of a new flat roofing system. We help you select the right membrane based on your building type, budget, and long-term goals.

Choosing the Right Flat Roof System

Not all flat roofing materials perform the same way, and the right choice depends on the building, the climate, and how the roof will be used. The most common systems we install include:

  • TPO (Thermoplastic Polyolefin): A heat-welded single-ply membrane that is highly resistant to UV exposure and punctures. TPO is one of the most popular commercial flat roofing choices for its durability and energy efficiency.
  • EPDM (Ethylene Propylene Diene Monomer): A rubber membrane with a long track record in cold climates. EPDM is flexible, durable, and handles freeze-thaw cycles well, making it a strong fit for Chicagoland properties.
  • Modified Bitumen: A multi-layer asphalt-based system that offers excellent waterproofing performance and is well-suited to roofs with heavy foot traffic or complex penetrations.

We walk every client through the options based on their specific situation and give an honest recommendation rather than defaulting to whatever is easiest to install.

Flat Roofing Systems Built for Chicago Weather

Chicago weather puts flat roofing systems through a serious test every year. Standing water from heavy rain, ice dam buildup along parapet walls, and the repeated stress of freeze-thaw cycles throughout winter can all accelerate the deterioration of a flat roof membrane.

The right material selection, proper drainage design, and quality installation are what separate a flat roof that holds up for decades from one that starts causing problems within a few years. As a flat roofing contractor in Chicago with 30 years of experience in this climate, we know what works and what does not.

Frequently Asked Questions

Do You Handle Flat Roofing on Historic Properties?

Yes. Many historic buildings throughout Chicagoland have flat or low-slope roof sections. We make sure the flat roof integrates correctly with any adjacent tile, slate, or copper components.

How do I know if my flat roof needs repair?

Common signs include water stains on interior ceilings, pooling water after rain, and visible membrane bubbling or separation. That said, some issues are not obvious from the ground, which is why regular inspections are the best way to catch problems early.

How Long Does a Flat Roof Last?

TPO and EPDM systems typically last 20 to 30 years. Modified bitumen can last 20 years or more. Regular maintenance is the best way to get the most out of any flat roofing system.

How Often Should a Flat Roof Be Inspected and Maintained?

At a minimum, once a year and after any major storm. Catching small issues early is the most cost-effective way to extend the life of a flat roof.

Do You Handle Emergency Flat Roof Repairs?

Yes. If you have an active leak or sudden storm damage, contact us right away. We will assess the situation and take steps to protect the building while a permanent repair is planned.

What Causes Flat Roofs to Leak?

Most flat roof leaks trace back to membrane seam failures, flashing separations around penetrations and parapet walls, or drainage issues causing standing water. Finding the actual source is always the first step before any repair work begins.
