🤔 What Is a Dormer?

A Functional & Stylish Roof Addition

Dormers are vertical extensions that rise from a sloped roof, typically housing a window. Their purpose is both practical and aesthetic—they bring in natural light, provide ventilation, and break up long or plain rooflines for visual appeal.

Why Add a Dormer?

• Increase headroom: Perfect for turning attics into livable space.
• Improve light and airflow: Especially helpful for upper-story rooms.
• Add curb appeal: Dormers create architectural interest that boosts home value.

📋 How to Choose the Right Dormer for Your Home

Choosing among the various types of dormers depends on a few key factors. Here’s how to narrow down the best fit:

Consider Roof Pitch & Style

• High-pitched roofs: Work best with gable or hip dormers.
• Low-pitched roofs: Accommodate shed and wall dormers more easily.
• Historic homes: Match original architectural styles for consistency.

Think About Interior Needs

• Need headroom? Shed dormers give the most usable space.
• Just want light? Gable or eyebrow dormers add light without major construction.
• Desire a view? Wall or hip dormers can accommodate larger windows.

Budget and Complexity

• Shed dormers: Typically more expensive due to their larger size and framing.
• Eyebrow dormers: Custom design means higher labor costs.
• Gable dormers: More affordable and simpler to construct.

✅ Pros and Cons of Adding Dormers

Pros

• Adds natural light: Brightens dark upper-story spaces.
• Improves ventilation: Especially when windows are operable.
• Expands usable space: Great for adding bathrooms, closets, or sitting nooks.

Cons

• May require structural changes: Altering roof framing isn’t a small task.
• More potential for leaks: Improperly installed dormers can lead to water intrusion.
• Adds to project cost: Dormers are an investment but offer long-term return.

⭐️ Installation Tips for Dormers

Hire a Qualified Contractor

• Experience matters: A poorly installed dormer can cause structural issues or leaks.
• Get permits: Many local codes require approval for roof modifications.

Plan for Insulation and Waterproofing

• Flash all seams: Water protection is key to dormer success.
• Use high-quality windows: Ensure weather resistance and energy efficiency.

Match Exterior Finishes
