Option 3 raising the roof to form loft conversion.
Loft conversion high pitched roof.
Rooflight loft conversions require the least amount of structural work to the existing space and are therefore the most cost effective.
Loft conversions in homes with low pitched roofs have always been a bit of a taboo.
The charts are there to provide people with an idea of what the actual slope will.
Trussed roof loft conversions.
Any angle above 30 degrees would work best.
L shaped dormer loft conversions.
Dormers not only give natural light but can add space to a loft conversion.
Dormer loft conversions are the most popular option as they are the easiest way to add light and an increased amount of roof space with full headroom.
Trussed roofs that are supported with wooden beams can still be converted.
The issue is that manoeuvring the beams into place at that height can be difficult so sometimes we opt to use shorter 2m lengths that are bolted together on site.
They are sometimes a requirement as apposed to full rear dormers if you live in a conservation area.
Mansard dormer loft conversions.
So a reduced space of 1 9m above the centre and 1 8m on the lower side can be acceptable as long as you can achieve 2m on the higher side.
The mansard type will give maximum conversion roof space because it projects the maximum available head height thus giving a greater usable floor area.
They are particularly effective where the pitch angle is high as the useful floor area can be increased.
Instead of the normal requirement for headroom of 2m above each stair tread it is recognised that ceilings to loft stairs may need to slope e g.
But it does still have its limits as you can only do this if you have high ceilings at the moment and the roof construction is of a particular type ie not truss s and ideally double pylons on each side.
Pitched roof dormer conversions lend themselves to large footprint or high pitched roofs.
The only changes made are the addition of windows.
Most loft conversions use steel beams to support the new floor structure and roof.
The roof structure is altered at the sides or rear of the house to add a large flat roofed box dormer.
An l shaped loft conversion uses two dormers which are joined together to form the distinctive l shape.
In order for your proposed loft conversion to pass building regulations it must measure 2 2 metres from the floor to the highest point.
Roof pitch conversion charts are very useful for one thing they give you all the information that you need to provide to the professionals.
Roof angle ideally the pitch should be at a higher angle so that the central head height is the highest possible.
