Modern roofing technologies can be a very good option for conditioning the air inside your house in cold areas in a cost effective manner. The roof can have a temperature of almost 150 to 190 degrees and the new materials for saving energy can be very useful for keeping the air temperature in control.
At the time of the replacement cycle that all roofs have, you should replace the roof of the old school design with the new and improved materials and save a lot of money on air conditioning. The cost of heating your house will be much reduced if the roof does a good job in keeping the cold air from entering the house and keeping the insides warm and cozy. There are a lot of extra materials that can be added to the roof for better air conditioning. You can get skylights that are designed to keep the solar warmth intact in the winter months.
