Will Roof Tile Vents Help?

[Holly64]

Hello

My dad's bungalow, built post war, is solid brick, no cavity and has a pitched tiled roof, there is also no ventilation in the soffits. In the summer, the bungalow is very hot and you really don't want to go into the loft.

We are going to have a PIV ventilation unit installed as the bungalow has now started experiencing some condensation issues in the winter. Looking at the instruction manual, the roof needs to be ventilated. I can get this done by having a few tiles swapped out for vented tiles.

My question is will these vented tiles also help the roof lose some of the excess heat in the summer. My poor dad has to have lots of windows opened and the back door just to let the heat out/get some air flow etc.

I cant answer the vented tiles question but can comment on the PIV system as that's what I have in my new build and they automatically switch off when the loft temperature rises to a certain amount. Just something to be aware off that they wont run 24/7.

So they don't run in summer and then in winter they do blow freezing cold air into the house as well, again something to be aware off.

Does he have plenty of loft insulation? It works both ways...
