- CUBE EXTENSION ROOF TYPES -
Here is a list of roof types that you may choose from for your Cube Extension. Please note that these are discussed at Engineer/planning stage and so there may be an additional cost for some roof types.
-
Flat Roof design (Standard design included in the prices quoted above)
-
Pitch Roof design with 18 degree slope - Pitch roofs require a minimum roof pitch (the slope of the roof) of 18 degrees. Once there is a minimum degree of 18, tiles and slate finishes can be used. There is also a wide selection of standing seam roof panels for pitch roofs.
-
Pitch Roof design with less than 18 degree slope - Where this occurs, slate/tile finishes can no longer be used. In this situation, we apply the membrane we use on our flat roof extensions. Examples of such roofs would be roofs with maybe 12 degrees, extensions at the back of housing estates.
-
Other roof examples we can carry out are Curved & Hip Roofs.
- OPTIONAL EXTRAS -
