The year was 1944.  Bernie Dalsin and two of his brothers decided to break from their father’s roofing company and form the Bernard L. Dalsin Roofing Company.  They grew quickly with a solid reputation for quality workmanship at a fair price.  Soon they were working with many of the leading Twin Cities property developers, general contractors and private owners.

Upon his retirement, Bernie’s eldest son, Dan, became the new president.  Working with other family members and loyal employees, Dan successfully lead the company up to his retirement.

In 2012 Dan and other family members sold Bernard L. Dalsin Roofing Company to Tony Spigarelli.  Tony came out of retirement with over 30 years of commercial roofing experience for the opportunity to own and operate the company.  He added several key people from his past company and BL Dalsin Roofing was officially underway.  Tony passed the reins to Don House on April 17, 2019.  Don represents the next generation of leadership at BL Dalsin Roofing.  He has the dedication and skills to lead our team forward for decades to come.

We are very proud to have installed the TWO LARGEST ROOFS in Minnesota.  In 2015, BL Dalsin installed the 19+ acre roof for the Amazon Fulfillment Center in Shakopee.  And in 2019 we completed the 26+ acre roof for the Digi-Key Electronics expansion in Thief River Falls.  Today, as we close in on eight decades of service, there is no building too large or small for a BL Dalsin roof!

Our Core Values

Our core values are incorporated into our Employee Handbook, training events, our bidding and our daily work. Our values dictate how we work with each other as well as with our vendors and customers.

Our roofs stand the test of time because we use only the best time-proven products and materials. Our attention to particular details makes the difference between a superior roof and an average one. Decades of service and dedication to quality have earned us a reputation envied by our competitors.

Our valued safety record reflects our commitment to our employees and our customers. Through employee safety training, jobsite safety audits and using the most current equipment and methods, everyone on the jobsite is protected.

We believe in giving our customers the very best service, before and after the sale. Whether it’s preventive maintenance or corrective action, our Service Team will provide solutions tailored to your needs. Our professional staff will help you protect your roofing investment over the long term.

The innovations we’ve brought to the roofing business are the result of problem solving through creative thinking. We’ve created new processes, special tools, and equipment unique to a project type or phase of work. This has resulted in overall efficiencies in projects and pricing.

Our installations are the result of skillful, masterful workmanship and superior project management. Our customers can trust us to deliver on time and on budget, but we will never cut corners or compromise on quality.
