A 4 12 pitch is around 18 5 degrees but not exactly.
Flare roofs contain more materials and are more complex so take longer to build.
Above all try to put in a great deal of effort at the design stage.
If the dormer has a pitched roof such as a gable it s framed with the same roof pitch as the original roof so it blends in.
Make a rafter cutting jig by measuring 12 in.
However certain designs can support various slopes.
Play around with the elevations until they look right.
As a result gable dormers vary in size more than most.
When the dormer gable is inspired by a classical pediment the pitch can be lower than the house roof down to about 5 in 12.
