"Roofing its something no home owner ever wants to do, but most have to go through. I won't even lie I wasn't even planning on getting a new roof, but Dale Knocked on my door and thats where the process started. My roof did go through insurance & aside from signing paper work/paying my deductible A1 handled everything. Obviously specific details from the insurance goes to you and then given to A1. Its not a short process and there is paperwork you have to sign, but all In all it did take me about 4 to 5 months where the process was started to roof replacement. Dale handled interactions with showing my the conditions of my roof and how to go about getting it put through the insurance. The only hiccup was that I have solar panels and I did feel like they where taken down to early (almost 5 months off), but I made my concerns known and one of the Managers called me and credited me $500 bucks (100 per month) that the panels where off. They did tell me setbacks in productions and things happen, but made me happy by giving me this credit. Didn't fight me on it, and didn't make me feel like I was just an insurance check on the other end. You can trust A1 home improvement with your home. I would like to thank Dale for his work & all the others that helped me throughout one of the most stressful process there can be for a house."

Absolute Building Solutions, LLC
Absolute Building Solutions LLC, also known as ABS Roofing and Remodeling, provides residential roofing and home improvement services in Connecticut. Established in 2014, the company began with general home renovations and has since refocused its work on roofing, including roof replacement, repair, and storm damage restoration with insurance claim assistance.

"Please see attached image for details Brian and ABS bring top notch customer service, consultation and knowledge to roofing, building and remodeling. They are timely, communicative and ensure that we as homeowners know all angles of a job. Top level craftsmanship and attention to detail they provide an incredible end project. They replaced our roof which is a steep tricky roof and were able to get it done in one day. Where our first floor roof meets the siding we had some rot on some siding along the roof edge. Brian looked closer and said half the roofline needed to be cut out. Instead of just replacing the bad siding, Brian cut out a line across the entire edge so that it would look uniform. He fixed and replaced the flashing and covered it with plastic wood. He recommended this for aesthetics and to help prevent any further degradation. Adding an additional unforeseen cost, we feel that the cost was competitive and fair for the amount of time, material and attention to detail. "
