Why doesnt sheep shrink when it rains?
Soffit-vents are not necessarily required, although, adequate air circulation isThere are different ways to obtain this( Soffits, gable-vents, ETC)The total cubit FTof your attic space will determine the size of the openings of the vents.
Yesthey are requiredIf a GOOD home inspector(not many of them) found out that there were none, it could be written up as a fault
mjd 1267 has the right answerThe system described it good for just about any locationIt provides for good ventilation in the summer to help keep the attic cooler and your house coolerIn the winter it helps prevent ice dams by preventings ice formation near the point where the roof meet the outside wallsThis has been addressed several time on various DIY shows.
That ammount of vents may be enough so long as the weather up in NJ doesn't get above 75 degrees in the summerSoffit vents help to circulate the air in the attic and help to remove any trapped hot air that might make it's way into your house and raise your cooling costsIf you don't have very hot summers, which I suspect you don't, then I believe what you have is enough.
A sheep's wool is Woolly or nappy-it is tightly curled and bunchedBecause wool is pulled taut and twisted in spinning into yarn, it will only remain so if kept dryWhen wet, the fiber returns to its natural Woolly stateBringing it back to psychology, it is in their natureEwe aren't 'all wet' for asking the question;)Wink!
