FAQs
From costs and system specs to warranties and maintenance, we’ve compiled answers to the questions Chicagoland business owners ask us most.
Pricing & Transparency
What does a commercial roofing project typically cost?
Every building is different, so commercial roof replacement cost varies based on factors like square footage, system type, roof condition, and access requirements. A flat roof replacement using TPO or EPDM will be priced differently than a custom sheet metal system. Rather than give you a number that may not reflect your building, we provide a detailed, line-item estimate after a thorough inspection, so you know exactly what you’re getting and why.
Are there hidden fees or upcharges not listed on your quote?
No. What’s on your quote is what you pay. We take transparency seriously; it’s one of the reasons clients have trusted us since 1979. Before any work begins, we walk you through every line item and explain what it covers. If something unexpected comes up during the project , we communicate it to you immediately before proceeding. No surprises.
Do you offer free inspections or estimates?
Yes. We offer complimentary roof inspections and detailed estimates for commercial properties across Chicagoland. Our inspections use advanced tools and provide clear photo documentation so you have an honest, accurate picture of your roof’s condition before making any decisions. Schedule your free inspection to get started.
Products, Systems & Specs
How do your roofing systems meet local building codes and city specifications?
All of our installations are performed by certified crews trained to meet Illinois building codes and local municipality requirements. We’re familiar with the permitting process and spec compliance across the Chicagoland area, including Naperville, Aurora, Elgin, Joliet, and surrounding communities. If your project requires specific engineering documentation or manufacturer certifications, we handle that coordination as part of the process.
How does your product compare to what we’ve used in the past?
That depends on what system you currently have, and we’re happy to walk through it with you. One thing clients consistently tell us is that we take time to explain not just our recommendation, but how it compares to alternatives, including what competitors may be quoting. Whether you’re moving from an aging built-up roof to a modern TPO membrane or upgrading from EPDM to a higher-performing system, we’ll show you the side-by-side case for each option.
What types of commercial roofing systems do you install?
We install a full range of commercial systems, including TPO, EPDM, flat roofing, custom sheet metal roofing, and energy-efficient roofing systems with reflective membranes and tapered insulation. Every recommendation is matched to your building’s structure, drainage, and usage needs.
What warranties do you offer on commercial roofing systems?
Our commercial roof replacements are backed by 20-year warranties. We also work with manufacturer warranty programs through partners like GAF and CertainTeed, which can provide additional coverage on materials.

What sets Showalter apart from other commercial roofing contractors in Chicagoland?
We’ve been in business since 1979, and that kind of track record only exists if you consistently do right by your clients.

How long have your crew members been with the company?
Crew retention is something we’re proud of. Many of our field technicians and project leads have been with Showalter for years. That continuity means you’re not getting a revolving door of subcontractors. You’re getting experienced professionals who know our standards, our systems, and what it takes to get the job done right.
Have you worked with companies our size or in our industry?
Very likely, yes. We work with commercial clients across a wide range of industries and building types throughout Chicagoland, from small businesses and churches to large industrial facilities and multi-building campuses.

The Project Process
What can you do to minimize disruption to our business during the project?
We plan every project with your operations in mind. That means scheduling around your business hours where possible, staging materials efficiently to keep access points clear, and maintaining a clean, organized job site throughout. For time-sensitive industries or high-traffic facilities, we’ll work with you directly to develop a sequencing plan before the first crew member sets foot on site.
What does a commercial roofing project look like from start to finish?
It starts with a free inspection and estimate. From there, we present a detailed proposal, walk you through the recommended system, and handle permitting and scheduling. During the project, your dedicated project coordinator is your main point of contact. After completion, we conduct a final walkthrough and provide documentation for your warranty.
How long does a commercial roofing project typically take?
Timeline depends on the size and complexity of the project, the system being installed, and weather conditions. A straightforward flat roof repair in Chicagoland may be completed in a day or two, while a full commercial roof replacement on a large facility may take one to two weeks. We give you a realistic timeline upfront and keep you updated if anything changes.
Maintenance & Long-Term Care
How do you handle ongoing maintenance after the project is complete?
We offer structured commercial roof maintenance programs that include annual inspections, minor repairs, and detailed photo reports—all handled in-house by our own crew, not third-party vendors.
How long does a commercial roof last?
With proper installation and regular maintenance, most commercial roofing systems last between 20 and 40 years depending on the material. TPO and EPDM flat roofs typically perform well for 20–30 years, while quality sheet metal systems can last 40 years or more.
What are the most common signs that a commercial roof needs repair?
Warning signs include water stains on interior ceilings, visible membrane bubbling or cracking, pooling water that doesn’t drain within 48 hours, and damaged or separated flashing around vents and HVAC units. If you’re noticing any of these, don’t wait, as delayed flat roof repairs tend to compound quickly into much larger problems.
How often should a commercial roof be inspected?
We recommend a professional commercial roof inspection at least twice a year, ideally in spring and fall, plus after any major storm event. Regular inspections catch small issues before they become expensive failures and are often required to keep manufacturer warranties valid.
