We have a lovely (8 years old) 4 x 11 metre patio on the north side of our house, with one of those metal roofs which has a ceiling on one side and a roof on the other, installed in strips. The problem is in summer, when the heat radiates down and bakes us, which means that we don't want to hang out on the patio, but also we can feel the heat radiating into the house from the patio. I've looked at those insulated ceiling panels, but they'd cost thousands, and the roof we have is still in great nick.
My husband is keen to insulate under the roof, but I'm reluctant to add insulation that will cover the attractive finish that is there, and concerned as to how to attach it without it sagging or looking rough-as. As we can't see the rooftop, I'd be interested in stopping the heat on top, if there is any possible way to do that. We recently used Foilboard (polystryrene panels with foil) inside the garage door with great success, but no insulation products I can think of are designed to cope with rain and sun exposure. One person I heard of simply stretched and tied on shade cloth along the top of the roof in summer, but not sure of how it would cope with windy weather. The roof is also a lightweight structure, not load-bearing, so anything added to either top or bottom would have to be lightweight.
Any suggestions out there? It was 40 degrees weather today, and if this is spring, I'm truly dreading summer, and need to keep on with adjusting my house for climate change.
