Engelmann Construction's 4 Main Cornerstones

  • 1 Family

    The Engelmann Construction family is located in our home town of Northport, NY, which is where our main office, yard, and shop are. Working together as a family business can sometimes be tough, but overall it's a gift. Our biggest challenge is stopping the shop talk at holiday gatherings.

  • 2 Philosophy

    As a family-owned and operated business, we take pride in servicing the needs of our clients. We are dedicated to being involved in our community, country, and the world through the Rotary Club, Kiwanis, and Island Christian Church. When it comes to understanding the blessing of being free people and Americans, we walk the walk and humbly pay it forward personally and professionally.

  • 3 Geography

    Although we are located in New York, we have regional (East Coast) capabilities with years of successful projects under our belts. One of the things we especially enjoy is staying accredited with certified teams in every roofing system. That way, we can present solutions to our clients based on their needs. It may sound a little commercial or pitchy, but it is 100% true.

  • 4 Safety

    Our teams are always supervised by an Engelmann Construction principle and as a result, we have a 98% satisfaction rate with a referral business that is the envy of our competition! Safety training and OSHA compliance are also extremely important to us. It's only roofing and we are not saving the world, but no one should ever get hurt working with us. That's the goal.
