Should also add that currently our loft is supposed to be a cold roof, but the geniuses who did it didn't actually put insulation in the floor of the eaves storage/ceiling of the bedroom below, or the little wall between that and the loft bedroom. And there's insufficient insulation in the main loft roof.
So even if you found some way to stop all solar gain as is, it just slowly heats up during the day anyway because there's no insulation between the roof tiles and a large part of the loft :/
Plan is to convert it to a warm roof as part of the work but given all the issues it's effectively a re-roof :(
