The average dormer cost is $4,500 for the framing, roofing, a window and finishing inside the home.
The dormer addition cost varies greatly by the four home addition cost drivers:
1. the location of the home which impacts the labor costs and to some extent the cost of materials.
2. the size and design of the dormer addition. A shed dormer, a gable dormer an eyebrow dormer, hip dormer all require different trim and roofing solutions on the exterior. The interior changes in the home are impacted as well by the type and cost of the window and the finished wall and floor surfaces.
3. who does the work. Will you build the dormer yourself and just pay for material or hire an architect and a general contractor to do all the work. Labor for dormers additions make up more than 50% of the cost of the project so who you hire to do the work will have a big impact on the final cost.
4. the materials you choose. The cost of the window, roofing, flooring and siding will have a big impact on the total cost of your dormer addition. If you choose lower cost asphalt shingles, a simple vinyl single hung window, vinyl siding and carpet floors on the interior your dormer cost could be 50% less than if you have tile roof, an expensive custom window, wood shake siding and hardwood flooring on the inside.
