Hot Porch Roof

Tony · 2009-07-25T20:47:18+00:00

I have a large front porch with a roof about 8 feet up. It is open on the bottom so you see the sheathing and joists (2x6's). When the sun is on it the heat really radiates down to the porch area making it hot as hell even though you are in the shade.I am considering putting up a "ceiling" but good circulation won't be easy without a fan. The porch roof extends about 10 feet over the original roof and shingles of the house so I suppose I could close it up and add a fan. If I do it I'm thinking of using 3.5" insulation so there is plenty of room for air circulation between the insulation and the sheathing.Any other ideas before I get broiled?Tony

With an air gap and air circulation, that's practical. But, the "idiot" poster proposed cutting the foam board into strips and packing it up against the roof.

Home Depot. 'Henry's Solarflex 287 SF'. Comes in a 5 gallon can. I don't remember the price. I painted my 20' x20' black asphalt shingle sunroom roof with it 2 years ago. It made a hell of a difference in the inside temps. Well, maybe 'hell' is the wrong word. :-) The roof is still white 2 years later.
