Shed Dormers Guide

Dormer construction has shifted noticeably with all the framing methods, roof integration concerns, and code requirements flying around. As someone who has built dormers in every configuration, I put in the hours studying shed dormer design. Today, I will share it all with you.

What Shed Dormers Are

Probably should have led on this subject, in fairness—shed dormers have a single sloping roof plane, typically lower pitch than the main roof.

Advantages

• Maximize usable floor space
• Simpler framing than gable dormers
• More natural light than skylights
• Increase headroom in attics

Design Considerations

• Minimum roof pitch for drainage
• Structural support requirements
• Integration with existing roof
• Window placement and sizing

Common Applications

• Attic conversions
• Second-floor additions
• Expanding headroom
• Adding natural light
