  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. I was so impressed with the foam roof they did and have not had a single leak since! Thank you guys so much!! 10/10 recommend

  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

  They did a nice job on our church's roof project. The entire process from estimate to completion was a good experience. Respectful employees. I do recommend Lengacher Construction Company.
