Flat or low slope roof conversion to sloped roof design.
Low pitch roof conversion.
If you can give them the exact chart and measurement that you like the look of they can work to those specifications.
These roofs have a pitch less than 4 12.
They have a pitch ranging from 4 12 to 9 12.
The original tar and gravel low slope roof lasted many years but ultimately a combination of roof age wear ponding and leaks led the owners to construct a gable roof over this building.
Conventional roofs are the easiest to construct and you can walk on them safely.

This article describes illustrates the construction of a sloped gable roof over the flat roofed home shown above.
First convert the pitch to a slope.
Low pitched roofs are generally difficult to maintain and you need special materials to prevent leaks.
For example their inability to shed rainwater promotes premature failure of the weathering membrane and its substrate.

Roof pitch conversion charts are very useful for one thing they give you all the information that you need to provide to the professionals.
To do this simply convert the rise and run as a fraction to a decimal form eg.
Of these probably the most challenging are buildings with shallow pitched roofs because standard space making solutions such as adding huge box dormers won t compensate for a chronic lack of headroom.
Even where a loft appears reasonably spacious prior to conversion the available headroom will normally have shrunk by at least 300mm by the time you ve added a new floor structure and insulated the rafters too.
