What customers say in Alton Bay, NH
★★★★★
★★★★★They could have improved in having the salesperson and foreman have a sit down so they are not disconnected and have the same information. Also, they should have workers that understand and comprehend English.
★★★★★
★★★★★This is the 3rd roof I've had installed by Interlock. I put one on my original house, my cottage, and now my new house. They have always done an excellent job, and the aluminum shingles are a great product — light, sturdy, and still looking good even years down the road.
