hot air rises so if you just put a vent in your roof, hot air will flow out of it.

It will suck in cool air if you put anothe vent lower down, or in the loft hatch or ceiling it will suck air from the rest of the house. Remember to close the "in" vent in winter

Purchase cost £low
Running cost £nil.

The problem is JohnD, I have 4 roof ridge vents and continue soffit vents and it still not enough air movement, also I have black tiles which collecting more heat. The loft roof room is hotter that the sauna!
