Department of Energy estimates that an attic with adequate insulation can reduce your heating bill by 10 to 50 percent. And it works the opposite way for hot climates; in summer, it helps stabilize the indoor temperature of the house to keep cooling needs under control. An insulated roof will save energy because air conditioning will be more efficient.
Duct leaks are also common in attics that are not sealed. roof insulation is a good option if you have an old house. Older buildings tend to have more drafts, so insulating the entire roof is a wise decision. The insulation of a roof is important under certain conditions.

Many people rightly want to know if insulation is a good investment before installing it in their homes. Termites can tunnel undetected through the insulation of the outer slab to access the wooden structure of the walls of a house. It has been proven time and again that insulation greatly improves the energy efficiency of homes in Australia.
A house with an insulating slab is easier to heat, and placing the mass of the slab inside the thermal envelope of the house helps to moderate indoor temperatures. A ventilation baffle must be installed between the insulation and the roof deck to maintain the ventilation channel. It can be difficult to access the roof space where insulation is needed, so loose-fill insulation installed by a professional is commonly used in this case. The main benefits of installing insulation in your home are greater comfort and lower energy consumption.
If your house already has roof insulation, it is worth checking if it is thick enough, since regulations have changed in recent years and it is not difficult to increase the thickness.
