I am changing from a combi boiler to a traditional tank system. In order to get the head of water needed to get some water pressure I need to put the tank in the roof space.
Living in a fairly modern house, I have proprietory roof trusses, will these take the weight of the water tank?
When a new house is built, the roof truss designer specifically requests the location of any tanks. Usually they call for a pair of double trusses where the tank stand is located. I think you would need to get this calculated by a truss company to be on the safe side.
Similarly, where roof windows occur, (Velux or similar) they usually require doubling up of the trusses either side of the window, often since the centres increase at this point to allow for a window wider than the standard 600mm centres.

What are the merits of Attic Trusses over traditional construction to create a large roof room in a new house?
Attic trusses, whilst more expensive and of heavier construction than normal roof trusses, are very cost effective. Normally a crane would be required but the carpentry labour element is small and lots of roof space can be started and finished in effectively a couple of days. The space in the eves becomes available as only cupboard space however.
Traditional construction relies on significant purlins to take most of the vertical forces/weight of the roof, and once the span of these exceeds about 4m, a steel beam (RSJ) is normally required. The rafters then span over the purlins but require horizontal restraint at the rafter feet. This is normally effected by bolting the rafter feet to the ceiling joists. This system however makes the entire floor space available to the finished room. This trype of roof space is very labour intensive since all ridge joints need cutting, and each rafter needs a ‘birdsmouth joint’ at the rafter points and also over the wall plate.
In summary, traditional construction is the perfect solution but attic trusses are a very cost effective alternative.
