Jack at Omega Exteriors was great to work with. He worked with our insurance company during the claims process and was extremely helpful and knowledgeable about our roof replacement options. Even when the wrong shingles were delivered they quickly corrected the issue. The correct shingles were delivered and installed the next day. The IKO Nordic Cornerstone looks great on our house. I would recommend Omega Exteriors for your roofing needs.
Great customer service, very quick to respond to text or phone calls, takes care of every concern. I would definitely use them again if in need of their services.
