What Customers Say About
Shawn and ACI
"I received three bids to strip the old roof and replace it at my home, ACI Exteriors was the successful contractor, they were not the least expensive but the quality of the materials and the integrity and professional knowledge from the owner Shawn Gaffney got them job. Value is the intersection of quality and cost, ACI provided excellent value. My neighbor commented to me how meticulous the staff was in cleaning the work site, after two months I have yet to find a single nail or other debris. ACI, in my opinion is worth consideration for your roofing project, you will be well satisfied."

"We had a serious problem in our attic and needed specific ventilation on the roof in order to resolve it. Shawn came over and looked at it and I explained the attic situation. He understood exactly what we needed, ACI came and installed a new roof with ventilation and we are very satisfied and they did a fine job…"
