Why Estimating Matters: Inside BMI Academy’s Essential Two-Day Course

What Makes a Good Estimator in Roofing Today?

According to Kevin, a successful estimator needs a blend of skills: “You need product knowledge, strong math skills, the ability to interpret architectural drawings, and solid communication. You have to understand what the customer wants and know how to achieve it with the right materials.” He also warns of common mistakes. “Most people default to m² estimating, which leads to inaccuracies. Our course demonstrates, using actual site drawings, why that’s often not enough.” And even for those not in estimating roles, understanding take-offs and material compatibility is essential. “Changing products after the estimate is done can lead to costly mistakes, especially if the new product doesn’t work with the rest of the system.”

Is the Course Right for You?

Whether you're new to estimating or a seasoned roofing professional without formal training, the course is designed to support all experience levels. “If you already know the products, that helps. But even if you don’t, the structure of the course makes it accessible,” Kevin says. “It’s especially helpful for people who’ve been working on-site but haven’t had much exposure to technical estimating.”

Where Estimating is Headed

Looking to the future, Kevin sees more digital tools entering the estimation process, but believes human expertise remains essential. “Software can speed things up, but you still need to understand whether what’s been calculated is correct. Technology won’t replace the need for product knowledge and judgment.” His advice for growth after the course? “Keep estimating. Use your customers' drawings, and learn from experienced estimators around you. That’s how you keep improving.”
