Dormer Type

Create a budget for your dormer addition and make sure to include the permits in it. Talk to the professionals at Center Island Contracting to figure out a dormer budget that fits your family’s needs and allow us to take it from there.


Obtaining permits for your addition might be the most time-consuming part of the renovation process, so leave anywhere from a few weeks to a few months to your timeframe for permits. The cost of permits will depend on the size of your dormers.


There is certainly no standard size for a dormer, they come in all types of sizes to fit into all different home designs. When deciding on the size of your dormer addition, consider the proportionality of your roof. If you’re adding more than one dormer, make sure their sizes are consistent.

Dormer vs. Skylight

Examine the pros and cons of installing a dormer or a skylight. Since you’re installing either option to a room with a slanted roof, you will want the option that is less likely to leak. Skylights are more cost-effective, so if budget is an issue, that’s something to think about.
