Framing a dormer in truss roof.

Building a roof dormer is an ambitious and challenging project. Framing a dormer refers to the first and most important step in constructing an upper level addition to your home. Whether you re expanding a cramped attic into a bedroom office or playroom if you have any carpentry experience you can accomplish this home renovation goal yourself. But 99 of the time a roof truss is going to give you so much more.

Sure there may be an instance where stick framing is your only option and that is understandable. With the dormer roof raised and supported we cut away the part of the original roof that was still in place leaving the exposed ends of the floor joists. Builders facing the job of framing a gable dormer generally use one of two options. Most simply build a header between two doubled common rafters from the main roof and use this to support the dormer s ridge beam.

To correct a slight dip in the floor we established a benchmark height with a laser level and nailed 2x6 squash blocks to the sides of the existing floor joists.
