"I've had ice dams for years. I finally researched it enough to realize it was an insulation problem (I wish I had been smart enough to figure it out sooner). Anyway Speciality Insulation came out and gave me a truly reasonable estimate. The technician found an uninsulated heating pipe, missing batts, in addition to the original find of inadequate insulation. They fixed all of that. I have a room that was perennially cold, it's warm now, no ice dams and I am sure my gas bill will go down. They cleaned up after themselves and were very pleasant people. Very pleasant, efficient and did what they said they could do for an affordable price."
