Commercial Roofing Services: A1 Roofing maintains an honorable reputation and track record for the installation, maintenance and repair of more than 10,000 commercial roofs across the tri-state area since 1981. Our full-spectrum expertise – from routine roof repairs to large construction projects, working hand in hand with solar contractors – has earned our roofing company the highest referrals and repeat business in the industry. 

KEEPING YOUR BUSINESS, IN BUSINESS:  For our commercial projects, expect caring and convenience. We understand the critical nature of staying on schedule and put you into the queue immediately upon contract. Need express service? We’re glad to bump your project to the front of the line for emergencies when time is of the essence. 

Trust + Integrity: Integrity in both business and craftsmanship resides at the heart of our family-owned company. And we want to share it with you. 

Customer Service: Your commercial building is unique – and so is our personalized service. We also welcome jobs of any size during our 40 years of operation. We stay responsive and cost-effective, keeping everything in house. From your first phone call through project completion, your project is our top priority. 

Insured properly for any size building: We have the proper insurance to work on your roof or on any sized building in the tri-state area. Most contractors have insurance for general contractor work. We have roofing insurance and we have it set up properly to protect our clients and their assets. 

Safety Measures: All of our field employees have OSHA-10 and OSHA-30 certifications. We take safety very seriously and want to make sure all of our employees return to their families safely.
“The A1 Group was built on a handshake and we honor to be true to
our word. Offering peace of mind to our clients separates us from
other roofing companies.”

OUR TEAM : Each of our projects has a dedicated manager and team of nearly eighty to one hundred roofing professionals trained and educated to complete roof repairs and installation at the highest quality. Being in business for over 40 years has provided us the knowledge and experience required to handle all of your roofing needs.
