Dormer Addition Costs

Adding a Dormer

A dormer is an extension to a house that protrudes from the plane of the roof’s surface. Most of the time, it usually runs horizontally at the edge of a house’s roof or in the middle of its slope. The window of a dormer is called a “dormer window”. To most people’s surprise, a dormer is a very affordable piece of architecture to add to your home, compared to the cost of buying a new and more spacious home. The cost of a dormer addition depends on its size and the labor that is involved, like most home remodeling projects

What’s The Cost of Adding a Dormer?

A single or double-window dormer cost will run at least $2,500 and more likely $5,000 or more. Where as a single or double-window dormer addition will be cheaper, a gable dormer addition will probably be among the most expensive dormer additions. The level of difficulty in creating a gable dormer is beyond most home do it yourself projects and will require professional contractors and builders. The cost of a gable dormer will run between $15,000 to $25,000.

This is not to say that this will ultimately be the cheapest and most expensive prices for adding a dormer addition. A larger than normal gable dormer will obviously cost more. A dormer addition that is room-size, and big enough for a bed, tables, and maybe a closet will have a starting price of possibly $20,000.  The dormer cost varies significantly by these four home addition cost drivers:

  • The size and design of the dormer addition. Ex. A gable dormer, a eyebrow dormer, a hipped dormer, or a shed dormer. All of these dormers require different roofing solutions on the exterior.
  • The dormer addition cost varies greatly by who is doing the work and how many construction workers are being used. The labor for dormer additions make up more than 50% of the cost of the addition. You will find that different companies have different prices.
  • The materials used.
  • The amount of time it takes to be built.
