Ordered metal roofing light-colored/reflective for tax credits, and our carpenter cut the top of the A in the frame to allow more ventilation, saying: "It will be cooler in the summer.", I said summer is not increasing power consumption, do not even use an air conditioner. What is the best way to save energy. After talking with others on the web, I found the answer. You can ask any advice from local suppliers – get different advice from different people – if you can. For the best advice, the location (city or town) of the house should be known. As your city is a cold region, a reflective sheet may not be required, as they are for the warmer climate. You must insulate the roof, but the ventilation is good for the summer so there must be at least one opening in the attic. You can use simple opening or fan or whatever suitable. You should be able to close it in winter, heat loss. Usually, there are vents in the attic and you can have the ceiling fan to suck the heat from the attic rooms so the insulation is not everything, but it is necessary. Always think 'passive design' – i. E. Natural ventilation and natural heat gain or loss. More openings in summer and winter least openings – which should be adjustable. Double glazed windows are better than single windows in winter. Too much insulation can be a problem, especially for the summer but ventilation can solve the problem. His carpenter may be an expert, but I dare not say – you have to check.
