Yes, there will be an additional cost to adding insulation, but a simple payback can be estimated on an individual basis. Additionally, one should consider this particular home improvement as an investment in increased comfort, building durability, and home value, as well as a hedge against rising fuel prices over time. You don’t get all that from a new living room set or an entertainment center.
In summary, if you are already planning on re-siding or putting on a new roof and you are interested in being more comfortable, saving energy and increasing your home’s value, you should take a look at adding more insulation. Please note: Given that the overall air-tightness of the house may be dramatically changed after roofing or siding, a simple blower-door test and a ventilation inspection should be conducted to insure occupant health and safety.
