Insulated metal roof

My home has vaulted ceilings with exposed rafters. I have 2”x 8” tongue & groove decking. There is no insulation due to this was a vacation home. We how live in the home year round. The home needs a new roof and we wanted to go back with a metal roof, but also wanted to somehow add insulation. What would be the best way to insulate without loosing the look of the vaulted ceilings? Is there any insulated (cost effective) metal roofing for home use?

Metal roofing is an ideal solution here and there a a few options depending on how much money you would like to invest to save on energy and which climate zone you are in. The Canadian building codes now call for an R40 insulation and the US codes diminish as you move south. I had an identical home to this. I removed the old roof material and then strapped the roof vertically with 2x4 on edge. Then I strapped the roof horizontally with 2x2 to accept a Dura-loc Tile roof. I had the space foamed in place which provide not only 4" of insulation estimated at R24 plus but also provided the interal air barrier with its low perm rating. This can be increased as required by moving to 2x6 which would also provide for the 1" vertiacl air space required by code if you use other roof systems. Hope this helps.

could you explain exactly how you did the insulation. Was it sprayed on with the 2x2 in place or before they were installed. how was the over spray controlled. How was the cost compared to using ridged foam board? We have a church cathedral ceiling the same as above. We need the most cost effective solution for our northwest Ohio location. Thanks
