"Acorn Home Improvements installed a GAF Timberline roof for us in July 2017. We rate our experience with them as excellent. The initial contact with Michael Sheehan was very pleasant as well as informative. He helped us choose the best roof to meet our requirements and provided us with a written proposal outlining the work to be performed, warranty features, and total cost. We chose Acorn to do our job based on the following factors: we judged their proposal to be our best value considering cost, quality and warranty; Acorn has credentials as both a GAF Master Elite contractor and an Owens Corning Preferred contractor; they could schedule us before the onset of hurricane season; they have received numerous positive online reviews; and Michael was responsive and easy to work with. Whenever we called Acorn’s office, Mary was there to pick up the phone. Mary is pleasant, knowledgeable, helpful, and thorough. Any questions or requests that we had were addressed promptly and effectively. The crew worked very diligently and efficiently, completing the job within the projected two-day timeframe. Ron, the head crew chief overseeing the work, was present the entire time. The cleanup was quite well done, and both the dumpster and residual material were removed in less than one hour after the crew had finished. We found all of the workers that we were directly involved with, including vendors delivering supplies, to be polite, considerate, and personable. We have only had the new roof for less than one month, but it evidently seems to be performing as expected. It certainly looks very nice and has elicited several compliments. To summarize, we are very pleased with the performance, results, and customer service provided by Acorn Home Improvements, and we would definitely contact them for future work."

"Excellent and professional company- all the workers were pleasant and courteous. Roof was done in one day- they did a wonderful job on clean up- haven't found anything on my property from taking off the roof and adding the new one. Would highly recommend using George J. Keller for a new roof. Love the new color of the roof, really makes the house pop!!!"

Another family member had used Manny in the past and was also extremely happy with their new roof!"

"After the heavy snow, our roof started to leak.It was full of snow and we were afraid nobody will give us a solution as long as it was with snow.We called several roofing companies and nobody was helpful until we called Everest Construction Group.They said they will send two guys the next day to help with the cleaning of the snow and inspect the shingles and the flashings where it might leak.They came cleaned the roof and found where it was the real damage.They repair it.After the repair was done they gave us an estimate for the whole roof installation and also suggested that is better to do the installation in March.We will call them.Very helpful, very professional.It is great to have this kind of companies around! Delightful!!!"
