Complete novice here, so please be gentle with me!
Our Victorian terrace has two attic rooms. There's currently no insulation in the roof, so they're freezing in winter, and sweltering in summer. What can we do about it, and roughly how much would it cost to fix?
As I see it, you either take the roof tiles off and put in insulation, or take the ceilings down from the inside. We need scaffolding anyway to fix chimneys and gutters, so doing this from the outside might be better? And less messy!
Or do we just cover up the existing ceiling with insulation; sounds less disruptive, but I'm guessing we would lose a lot of space because of the sloping roof?
