Due Diligence Series Part 1: How to Select Your Next Commercial Roofer

In our current fragile economy, best value is not always defined by price alone. In harder times, smaller companies with little to no experience installing commercial roof systems commonly attempt to take on commercial roofing projects without the proper experience, manpower, equipment and insurance. Most often this results in devastating consequences for the building owner. A commercial roofing system that comes cheap but is poorly installed by an amateur with inadequate resources can lead to premature roof failure or worse, persistent leaks and hassle, easily placing a company in financial risk and undue stress. So how can commercial building owners avoid this disastrous scenario? Accurately determine who is the most experienced and accomplished commercial roofer offering the most dependable and cost-effective long-term solutions?


There’s no quick easy answer. Sites likeAngies’s ListHome Advisor,and BBB.orgonly provide some of the key information you need to make a decision this large. The best and most comprehensive solution is to perform your own due diligence and verify the qualifications of your commercial roofer before you enter into any contractual obligation. If your company doesn’t have a process already determined for selecting vendors or contractors DCI has developed our “Due Diligence Series” of articles and documents which outline the salient questions to ask when evaluating a commercial roofing firm for quality, dependability, safety and expertise.
