Are black concrete roof tiles for my house uncomfortably hot even with roof under sheeting and insulation?
Black absorbs the suns rays. You're going to have to put vented windows in the attic. One on one side and one on the other side for ventilation if you don't already have them. There are also attic fans...take your choice. Purchase a fan that serves your purpose. As for the venting on the roof I still think it's a good idea for more ventilation.
it somewhat is a query of effortless warmth absorption the darker the colour, the greater mild is absorbed. an identical applies for warmth. The darker the colour, the greater warmth would be absorbed. think of of once you dress your self to circulate out on a warm and sunny day, you're unlikely to positioned on black top? The darker shade will help interior the iciness if there is little snow on the roof. on the grounds that warmth would be absorbed, your furnace will artwork much less saving you basically somewhat electrical energy, oil or gas based what you return to a determination to put in the living house. desire that helps =)
If you sit on them, they will be uncomfortable on a hot sunny day. If you mean in the house, the "under sheeting" or radiant barrier should deflect much of the heat from the roof, and keep your house easy to cool.
It would be easier for you to keep your house cool if the tiles were white, or at least terra cotta. However, if you have good sheathing and insulation, it shouldn't be outrageously expensive to have black tiles. If you live in a climate that has snow, the black tiles should absorb enough heat that you won't have to go up there and shovel snow off.
I wouldn't get bogged down by it. It depends on you're area and what you want to use the loft for. But the insulation will keep it ok inside. Just add some air bricks to encourage ventilation. This will keep you're heating bills down, and unless you're going to be living in the loft I really wouldn't worry. There are a lot of variables to consider. Just stick you're logical head on and you'll find your own answer. Just consider what the Canadians say; "Insulate tight and Ventilate right".
