WHY RSL?
Expert Analysis & Design
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.
Top Rated Workmanship
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.
Competitive Pricing
Having been doing this exact style of work for over 26 years, our pricing is always competitive and market sensitive. Our focus is on providing the greatest value to you.
Long-Term, Full-System Guarantees
The truth is, most guarantees in the roofing industry aren’t worth the paper they are printed on. Limited warranties on materials with a contractor’s labor guarantee are a recipe for backdoors and shifting blame. What if you have a leak and then the manufacturer comes out and says there’s nothing wrong with the materials- it was just installed incorrectly? What if the roofing contractor goes out of business 3 years in to your 20 year guarantee? There are many more scenarios but you get the point. A new roof is too large an investment to take that chance with.
That’s why 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%.
Technology Driven Process
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.
Industry-Leading Online Project Management
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.

Why we do it?
Our mission is to challenge the status quo in the industry and change the way our customers view the roofing process. We start by listening- not talking. For the most part, people don’t know a whole lot about roofing- and why should they? Roofs can last for 20, even 30 years, so the roofing process isn’t something people have to deal with very often. When it comes time to “do something about the roof”, most people start the process at square one. Our entire “sales” process doesn’t really involve much “sales”. We want to give you the tools to make an informed decision through education, a conversation about your specific goals / needs for the next roofing system, and providing the most economical options that fit your stated objectives.
Our report will contain:
Photos with detailed descriptions of the issues at play, that were written up for your report specifically- not pre-canned text from a software program.
Cross section CAD sketches of the existing roofing system as well as sketches for each of your options.
Detailed Roof Plans noting every item on the roof as well as secondary plans that map out exactly what we are proposing.
Industry-based recommendations and manufacturer submittals.
Contrast our approach with the “one-page” proposal from so many other roofing contractors and you see why we do it.
