Most of the old slate roofs are self-ventilating. The deck is made of boards with spaces in between them (from shrinkage)and the old felt paper has dried up. Air can move through this. It's when you have plywood and peel and stick membrane that you have ventilation problems. On the other hand, you may consider adding roof vents: http://josephjenkins.com/store/roof-air-vents/ Gable vents can be a good approach as well. If you insulate your ceiling, then the space above it in the roof should be the same temp as outdoors, year-round. | ||

To vent properly, you need an intake and an exhaust. If you are redoing the room, now is the time. It will require putting in some soffit ventilation, perhaps installing same rigid insulation between the rafters with an air space beneath the roof decking, and then an exhaust in the upper attic space. Perhaps a power vent or a gble vent or a power gable vent. Email me if you need specificas. good luck. | ||

So we've lived a finished attic since we bought our house a few years ago. (1920 Victorian with slate roof). From the way the heat/cold is in that room and how hot the physical ceiling gets I'm guessing there is little to no insulation above the beadboard ceiling. We're redoing the space. My question is venting the ceiling. I know i need to put vents between the rafter joists. How do I vent through a slate roof? Do I have someone add vents? Kind of lost on this one. |
