Loft conversion roof truss modification.

Roof trusses offer a quick and efficient alternative to a conventional timber roof but they re quite delicate when not in their fully braced vertical position. The central w shape is how most of the loads are distributed and this is where. Even though townhouse loft conversions have become extremely popular in the last couple of years the process of transforming a common truss into an attic truss isn t as easy as it may sound. If the roof slope is steeper than 9 inches in 12 inches of run it doesn t take much width to end up with a nice room 12 feet wide with an 8 foot.

Because of the design of the truss frames the loft conversion may require a structural modification so if you have this kind of roof it is essential that professional structural engineers are consulted. Attic trusses have a rectangular shape inside each truss. The main problem with raising the roof is that it requires planning permission and there s a fairly good chance this will be refused especially for terraced. Room in roof trusses can be craned into place to form the shell of a ready made new loft room with the insulation placed above the rafters for maximum thermal efficiency.

The lack of headroom in the existing roof space will be a further reason to alter the structure of the roof. However once a truss roof has been restructured and the loft converted they usually offer large spacious rooms which can be converted into excellent additional accommodation within your home. According to the nationwide building society adding a loft conversion to your home can increase the value of an average property by more than 54 000. Having a home with a trussed roof design should in no way stop you from planning and building a successful loft conversion.

The sad fact is your builder could have installed attic trusses over this garage for just slightly more than what the existing trusses cost. Looking back i was very lucky in that my roof had an unusually high 47 degree pitch and so there was lots of head room. They work through a combination of tension and compression to ensure that the timber chords and web sizes can be kept to a minimum and keep costs down. The w shaped trusses are replaced with a shaped trusses or horizontal beams.

This coupled with the slightly more complex construction and restructuring needed means that converting a truss roof can be more expensive than a normal loft conversion.
