Energy Savings by Installing Ridge Vent

powerfool

My house is about six years old now and we have had some heavy winds that have damaged some of my shingles. I checked my warranty and the shingles were protected by the home warranty for one year and the shingle manufacturer warranty for 15 years, but only up to 75mph winds. Unfortunately, our winds have been in excess of 75 mph on a handful of occasions. As such, I am looking to replace the shingles (just install them over, as the existing roof is the only layer of shingles) with new shingles that are rated to 115mph (I don't anticipate getting near 115mph, but that should ensure that the shingles won't be damaged by winds).

While I am up there, I would like to install a ridge vent to increase the ventilation in my attic. Currently, there are three of the decorative vents under the eaves just below the ridges, a turbine vent, and some small soffit vents about five feet apart. Has anyone performed this project before and noticed a difference in cooling costs during the summers? This should actually improve ventilation all year round, which is good for keeping the attic dry and it will keep ice dams from developing after snowfall. I also imagine that I will have to increase my soffit ventilation and ensure that the insulation is not obstructing the airflow.

As an additional option, I may install a radiant barrier in my attic to keep radiant heat out in the summers and in during the winters.

Does anyone know of any wizards or online calculators that can estimate energy savings?
