To introduce fresh and cool air to your attic, as well as let hot air escapes from the top of the attic through ridge vents you may consider adding soffit vents. The cooling costs for your house can be reduced using and the job itself is easy enough for you to handle.
In order to determine how many will be needed along each section you must first measure the area where you want to install the vent.
Use a template made of wood to mark the cut lines for each location that has been cut a little smaller than the size of the vent you’re installing. It should be an inch shorter and an inch narrower than the actual vent.
For a nice finishing touch paint the vent to match the soffit.
“No one will notice it is there except you and you utility bill.”
