Hi All -- I've recently purchased a Queen Anne Victorian built in 1895located in Medford, MA. The attic/3rd floor (yes, there is a room up there) has zero ventilation. No soffit vents, no ridge vents, no gable vents, etc. As you can imagine, it can get blazingly hot up there. While I don't have a temp reading, it had to have been 120F+ on some of those really hot days we had earlier this summer. The previous owner had an insulation company come in and insulate the attic floor and also added 20" of cellulose and fiberglass insulation in and around the eves and turrets. So at least the heat doesn't make its way down into the 2nd floor (much).
While we have no immediate plans to finish off this space (the current room is unused and looks like it hasn't been used in 50+ years), we would like to at least have the option of doing so in the future. And of course, I need to replace the roof this fall so now would be the time to add ridge vents, etc. The roof line is complicated with the turrets forming valleys and hips as well has forming "islands" of higher roof lines than the rest of the roof. And to complicate things, there are no soffits around the turrrets but decent-sized ones around the straight lines of the roof.
So the biggest question is whether or not I should move forward with adding ridge vents during the reroofing, then add soffit vents to the areas where it is possible and if this will be enough. What (if anything) can be done to the turrets to promote air flow up and out given their higher height than the rest of the roof?
The other option is to do nothing but I've heard of premature roof/shingle failure on houses where the attic isn't properly vented due to the extreme heat buildup.
Anyone else have to deal with a similar situation?
