One of the most interesting aspects of a home inspection is going into the attic space. This is an area where few homeowners venture and provides plenty of valuable information as to the condition of the home. One such important detail is ventilation. Do unfinished attics where nobody spends any time in really need ventilation? Absolutely!
There are several reasons why poor ventilation needs to be corrected:
Fortunately, attic spaces generally don’t need a lot of regular maintenance, but they should be checked at least a couple of times a year. One of the biggest issues I see are rafter baffles that have been knocked out of place by high winds. They are pictured in the diagram below and keep the soffit vent free of insulation.
How do you know if you have ventilation problems? Of course, you can always contact your friendly neighbourhood home inspector for help but here are a few clues that it may be time for further investigation.
