For over 30 years, Roofing Solutions LLC has been helping commercial building owners make the smartest roofing decisions—rooted in experience, driven by technology, and executed with true craftsmanship.
We’re not just in the business of installing roofs. We’re in the business of protecting your property, extending the life of your building assets, and delivering solutions that create long-term value.
Our company specializes in re-roofing existing commercial buildings, using the latest diagnostic tools—including infrared drones and moisture mapping—to design roofing systems that are tailored, code-compliant, and built to last.
But we know that not every roof needs to be replaced right away.
That’s why we also offer targeted repairs and proactive maintenance programs designed to extend roof life, reduce emergency leak calls, and help our clients plan ahead with confidence. By addressing issues early, we help property owners avoid costly surprises and maximize the performance of their existing systems.
Roofing Solutions LLC was founded in 1992 by John Leslie, with a focused mission: to provide expert re-roofing services for existing commercial and industrial buildings throughout the Chicagoland area. From day one, our goal has been to combine technical precision, honest and transparent reporting, and world-class workmanship to deliver roofing solutions that stand the test of time.
We quickly earn a reputation for raising the bar on professionalism. By delivering the most complete and thorough roof reports and proposals in the industry, building owners gain a new level of confidence in their roofing decisions.
Our Service Department launches, bringing short-term, mid-term, and emergency leak repairs to clients across the region. We shift from reactive to proactive problem-solving, helping businesses manage roof issues before they escalate.
We introduce Solution One, our dedicated roof maintenance division. This program evolves our mission to include lifecycle planning, budgeting, and warranty protection—helping clients extend the life of their roofs and reduce long-term costs.
Roofing Solutions LLC begins offering handheld infrared inspections, giving property managers smarter insights into hidden moisture and damage. This marks the start of our ongoing investment in advanced diagnostics.
Drone technology becomes part of our inspection process. By capturing aerial views, we deliver more visual, accurate, and valuable reports for building owners and property managers.
We launch drone-based infrared scanning, combining thermal imaging with bird’s-eye visibility for the most advanced roof diagnostics available. In addition, we expand into rooftop solar, partnering with a trusted provider to offer turnkey roof + solar solutions that help clients reduce energy costs and take advantage of clean energy incentives.
Every report and re-roofing proposal we provide is designed and handcrafted by true roofing design professionals - not just a sales person. All elements of design criteria are studied, researched, and evaluated for your specific roofing project- considering things like insulation r-values and energy savings payback, building geography and wind zones/uplift requirements, positive drainage and tapered insulation systems, and many other facets of technical design. When you receive our comprehensive report package, we want you to feel that it is the most comprehensive and well-designed solution that you have received for your project.
Having worked side-by-side with Johns Manville’s technical and training department heads for decades, our crews learn from the best in the industry. Ongoing training to maintain the highest level of quality has been a cornerstone of our company since day one. As a result of this commitment, we have never had a warranty claim in the company’s history and are ranked among the top 10% of all approved contractors in the Midwest region. Every customer deserves our best effort and we will settle for nothing less.
Having been doing this exact style of work for over 31 years, our pricing is always competitive and market sensitive. Our focus is on providing the greatest value to you.
Every re-roofing project we complete comes with a full system guarantee directly from the manufacturer- Johns Manville’s Peak Advantage Guarantee. As a single source guarantee, the manufacturer guarantees the materials and the workmanship on a no-dollar-limit basis for the entire life of the guarantee- 20 years or more. You benefit from having expert quality control throughout the entire process with the manufacturer’s technical department and inspectors acting on your behalf to make sure your new roof is installed perfectly to their specifications. At the end of the process, Johns Manville, a Berkshire-Hathaway Corporation, stands behind your new roof 100%.
At RSL, we stay on the forefront of technology and use things like infrared thermal imaging equipment (ground and aerial based), HD production quality drones with high-resolution photos and 4k video, industry-leading production and reporting software, and many more tools to provide the most positive, complete, and robust solutions to our customers. We place a high priority on our customer’s experience with us and these tools help us create one that rises above the competition.
From daily reports delivered right to your inbox during re-roofing projects to custom portals containing inspection reports, budgeting matrices, and executive summary style reporting, our Solution One Online Portal gives you access to all your roof’s information from the palm of your hand. You can expect complete transparency and communication when working with us on any roofing project.
