The Complete Cost of Changing a Roof Line
Is your home starting to feel small? Has your family outgrown your current one? Maybe you have an elderly parent you would like to live with you but don’t have enough space available. Maybe you could just use more storage but don’t have space outside to build a storage shed.
Is moving your only option? The very thought might even make your head spin.
What if you remodeled your home instead? Even if you don’t have space on the ground, you can raise the roof to add a full or partial story to your home. Let’s take a look at the cost to raise a roof.

Reasons for Changing the Roof Line or Raising the Roof
First of all, let’s look at why people choose to raise the roof or change the roofline. Common reasons include:
- The home doesn’t meet your family’s needs, but you still love the location
- Remodeling the home would be cheaper than moving (i.e. realtor fees to sell, moving expenses, etc.)
- You want to add your own unique character to the home
- The home’s low slope or flat roof is having problems with leaks
There are a few different methods for raising the roof. You might raise the entire roof to add another story or expand on your attic space. You can change the pitch of the roof for aesthetic purposes or to avoid leaks. Finally, you can add interesting elements like dormer windows (which also creates a little more usable space) to add a unique touch to the home.
The Cost to Raise a Roof and ROI
Let’s start with the cost of raising the entire roof. You may do this to add a new story or simply raise the ceiling. Some older homes have 7-foot ceilings and today’s typical ceilings around between 9 and 12 feet.
Obviously, it will cost more to add a whole new story, but let’s give you some estimates to work with.
Costs of Planning and Permits to Raise a Roof
Even though you own your home, you’ll still need a permit to raise the roof. This is to ensure that the work is planned and completed to meet safety and structural regulations. You’ll need:
- To have an engineer or architect draw up plans for the new walls: $250-$700
- To create a site plan detailing the changes that you can submit to your local building or development department, and possibly your HOA for approval: $99-$159
- A building permit. The cost will vary depending on what the permit covers: $450-$1500
Once you have secured your permits, the work can begin. It starts with removing the old roof.
If your current roof is newer or still in really good shape you may be able to save some of the materials. This will cost more to remove but will lower your new construction costs.
- Remove the roof and dispose of it $4-$7 per square foot
- Remove the roof and preserve materials for reuse $6-$12 per square foot
The home is now exposed to the elements so the new walls must go up quickly. Plan to spend $14-$22 per square foot. Any elements such as chimneys, vents, and stacks must be extended as well.
Then the new roof goes on and the new exterior walls get siding $15.00-$18.00 per square foot.
Cost of Finishing the Interior
The cost of finishing the interior will depend on how fancy you want to get. Basic drywall is cheaper than adding windows or decorative elements. Plan on $5-$16 per square foot.
After all this, what’s your ROI? If you’re raising the roof just to heighten your ceiling, you’ll get a fairly low ROI of around 47%-53%. If you’re adding a new story, expect an ROI of around 70%, depending on how you finish it. For example, a guest apartment gets a higher ROI than a bonus room.
The Cost and ROI to Increase the Pitch of Your Roof
Increasing the pitch of your roof incurs many of the same costs. Here’s a quick breakdown:
- Engineer or architect fees: $250-$500
- Site plan: $99-$159
- Building permit: $450-$1,000
- Remove the old roof: $5-$8 per square foot
- Extend gable walls: $14-$22 per square foot
- Build the new roof structure: $16-$22 per square foot
- Install new roof and siding: $15-$18 per square foot
- Finish the interior of the gable walls: $5-$16 per square foot
Increasing the pitch does wonders for improving the aesthetic of a boring, flat-roofed home. It also improves the home’s structure and reduces the potential for leaks. However, overall the ROI isn’t that amazing. Expect only around 50%-54% for a project like this.

The Cost and ROI of Dormer Windows
Adding dormer windows is an excellent way to create more usable space without raising the entire roof. This is most practical when you already have a small attic that you can extend out with dormers and create a kid’s play area or small office with lots of natural light.
The project is less extensive, helping to keep the costs down. You’ll still need plans from an engineer or architect $250-$500 and the building permit $450-$1,000.
Aside from that calculate:
- Removing the portion of the roof and cutting the roof deck: $3-$4 per square foot
- Framing the dormer: $19-$32 per square foot
- Installing the siding and new roof: $15-$20 per square foot
- Finishing the inside: $50-$110
While dormers are less expensive overall and add some usable space, which is better for ROI, it doesn’t add much. The ROI for this project is still quite modest at around 52%-58%.
