Framing with shed dormer over door low roof.

Make sure that you do not ruin the joist structure of the house frame. Due to the shed s design a significant amount of rain runs off the rear of the shed. For slanted roof sheds overhangs add character and facilitate proper drainage. Make a rafter cutting jig by measuring 12 in.

A rake on the gable end of the roof can be created with the construction of additional roof framing. Any flatter and the face of the dormer wall can appear awkwardly tall. The whole dormer might protrude by a disproportionate amount almost bug eyed from the roof. Since it s a shed and the dormers probably aren t to wide maybe 4 and you just want a window in each one without knowing how far your coming in plus you don t want to come to far in because the further you come in your main roof rises higher and higher which means shorter windows or higher dormers and lower dormer pitch roof.

Depending on the main house frame you can build a dormer all the way along the roof line and its frame will be sitting on the main house frame. Careful measures will determine the size of your shed dormer. Along the level line and using a square to draw a perpendicular line up to the roof edge of the board.

Framing the dormer 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. Use your template roof to measure and cut angled truss boards then screw them together and into the end caps. Add support boards and then screw the entire truss structure on top of the corbels.

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.
