Framing With Shed Dormer Over Door Low Roof

Along the level line and using a square to draw a perpendicular line up to the roof edge of the board.

Framing with shed dormer over door low roof.

Of course a shed dormer s roof slope needs to be shallower than the primary roof slope but it s best to keep the dormer roof slope at least 4 in 12 or steeper. 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. Install the corbels flush with the top of the door trim and against the side door trim. Make a rafter cutting jig by measuring 12 in.

Add support boards and then screw the entire truss structure on top of the corbels. Any flatter and the face of the dormer wall can appear awkwardly tall. If the slope of your dormer roof is the same as your old roof hold a scrap of plywood against the old roof boards and draw a level line on it. Careful measures will determine the size of your shed dormer.

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. Due to the shed s design a significant amount of rain runs off the rear of the shed. 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. 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.

An overhang helps direct water away from the foundation on the shed s low. Make sure that you do not ruin the joist structure of the house frame. For slanted roof sheds overhangs add character and facilitate proper drainage. 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.
