Cottage ceiling renovation

Hello - I'm wishing to remove the current drop ceiling from my uninsulated, seasonal cottage (NY) and cover the existing rafters with tongue and groove pine. The cottage can grow very hot sometimes in the summer, as the (metal) roof is not insulated. The rafters are 2x8's, and I'm not sure that I would have any room to insulate plus use vent baffles between the insulation and roof. The roof is flat and is pitched at a slight angle from front to rear, with soffit vents on both ends. Just wondered what my options might be if any, thanks very much, appreciated.

Pictures of ceiling, showing front and at mid-cottage wall (I would only be adding the tongue and groove the mid-cottage wall, back ceilings are small bedrooms and would remain as is with drop ceilings.)

 

Why not remove the drop ceiling and frame it up for your new ceiling at about the same height? Obviously you'd add insulation. What do you have for ventilation?

 

You say you have soffit vents, do you have a ridge vent to allow any ventilation to escape? Baffles and insulation will provide enough room for movement of the air, but it needs a place to vent at the peak (it you want to call it a peak).

 

Was hoping to use the existing rafters to nail the tongue and groove pine, Thanks for the idea, makes much more sense than what I was thinking - framing joices for a new ceiling which could be a little higher (1' or so) than what's there now. The only ventilation are small vents on each front side of the cottage (one can be seen in first pic, bright spot), plus soffit vents which run full length of the cottage front and back. Not sure how to properly insulate while providing ventilation between insulation and roof though with the ceiling rafters only being 2 x 8's. (Insulate above new ceiling?) Thanks again

 

No ridge vent - roof is flat, covered with metal and angled slightly. There's soffit ventilation on front (facing lake) and back (facing road). I only want to change the ceiling in the front half - I'll post a pic of the place...thanks again

 

If you raise the ceiling 1' won't the gable vents be below the ceiling? You want to have enough room for the insulation and not restrict the air flow from the soffit vents. Baffles can be used to give the soffit vents access to the rest of the 'attic'.

 

Actually, the front vents are high near the rafters and should be clear if I raised the ceiling a bit. Here's a pic of the cottage front showing vents...
