  Lengacher roofing did our bakery roof and did a great job. We had been having increasingly bad leaks in the past and decided to go with them due to their great customer service and insight.

  Lengacher does great work in a timely manner and for a great price! Highly recommend these guys! They are top notch!  We've had zero issues since they resealed the roof of our 200,000 square foot shop.

  John and his team provided a solution for our commercial building that was exactly what we needed. They provided a wonderful solution that encompassed the longevity of our building and met a fair budget. Their communication, job site cleanliness and follow-up have been superb. I look forward to updating this in the future and singing the same praises
