In this blog post, we cover how to extend roof line. The first step is taking measurements from the wall of your house and using a calculator to determine the pitch of the slope for your new extension. Once you have determined what pitch you will need, use a straightedge or ruler to mark where you want your new roofline.
If you are going with a gable-style roof, make sure that it slopes down at least 2 inches for every 12 inches in height. When designing the new roofline, ensure that you take into account any overhangs on either side of the building and, if needed, make adjustments accordingly! If all goes well, once completed-you’ll have an extra room!

15 Steps to Follow on How to Extend Roof Line
Step One: Using the Outline of the Roof as the Base
To begin, you should draw out the roof by using the outline of that roof as your base. You can do this by following its contours and seeing where it slopes down, then marking those points on your paper. So begin by outlining the roof and then keeping where it slopes too.
Then, draw a line from one end of this slope to the other. This will be your point of reference. Next, determine which direction you want the extension to run and build it on that side of the house or building’s wall. This should give you an idea of how many rooflines to extend.
Step Two: Adding More to the Extension
To continue, draw the extension by adding more length to either side. This will help you get an estimate on how long your extension should run and where it might be placed on your reference point. Once again, please do this by drawing out the base of the roof and marking it where it slopes downward. Then, if you have an angle, draw a line from one edge of this downward slope to the other.
You can also build a new side onto this first side if necessary. Use the lines you drew to create new roofs on either side of the line. Remember that if it is not straight, your roof will slope or curve. Before you erase any part of your diagram, save it with another name so that you can come back and make changes if needed. That way, if your extension size does not work with your room, you can make the adjustments.
Step Three: Adjusting the Extension’s Size
You may need to make a few different versions before making one that fits in your home. Once you have a version that will work, make sure you save the changes.
You can make a roof extension work for your home by simply erasing parts of it until it looks like an appropriate size and shape. To make your extension fit your home, you’ll need to erase parts of it until it looks how you want it to look. You may need to try out a few different versions before you make one that works. Then, when you have a version that looks good, save the changes.
Step Four: Placing Your Roof Extension
Now that you’re happy with how your roof extension looks, it’s time to place it. First, make sure the surface where the roof will be placed is flat and dry. If there are any objects under the roof’s surface, use them as reference points. This can help you find any problems with your extension and determine where it will fit best.
Fixing or correcting roof extensions is an easy task that can be done by simply erasing parts of it until it works with your space. It may take a few tries before you get it how you want it to look. You can extend a roof by simply erasing parts of it until it looks like the right size and shape.

Step Five: Building on the Extension
Now, it’s time to build your roof extension. First, make sure that the surface where you’ll be working is flat and dry. If there are any objects underneath this surface, use them as reference points. This can help you find any problems with your extension before building it and determining where it will best fit.
You can build the extension by adding more roofs on top of it. This will help you understand how to best design it and how long it might be. Keep in mind that if you need to change the height or length, you can erase parts of your extension until its size works with your space.
Step Six: Making Adjustments
If the extension is too small, erase some of it. If you need to make the roof bigger, add more roofs to this extension. When adjusting your roof extension, remember that if it’s not straight, then your roof will be slanted or curved. You can adjust your extension by erasing parts of it until it’s the right size and shape.
When you’re done or satisfied with your extension, erase all the unnecessary lines. There should be no stray marks other than what you need to show the size of your roof. Let’s look at our example again before erasing any lines. Again, there are no stray marks other than what is needed to measure the length of the roof extension.
Step Seven: Erasing Unneeded Lines
To erase any unwanted marks, use a kneaded eraser. The advantage of using a kneaded eraser is that you can mold it to get into small crevices. This is helpful if you’re having trouble erasing a specific spot. Likewise, you can erase parts of your extension using a kneaded eraser to get into small spaces and clean up the area.
While erasing, make sure you do it in the correct order. For example, start from the top and work down to the bottom to erase your roof extension. This way, you won’t accidentally erase lines that you need as reference points or as measurements. If you want to find out more about how to extend roof line, keep reading.
Can You Extend a Gable Roof Line Without Gutting the Whole House?
Yes! And here’s how. Many older homes have an interesting feature known as a “wing wall” that extends the home’s roofline. This might be because it is an addition to the second story, but this was very common in Victorian homes and can be seen in many decades-old homes today.
This is a simple way to add architectural interest to the front of your home, and it’s an excellent place for a dome or bay window. However, you might not have room for one on the main roofline that runs across the front of your house. In this case, you can add an extension. Although it looks complicated, the process isn’t too tricky.
How Do You Join Two Roof Lines Together?
One of the most common issues when installing a new roof is joining two separate roofs together. There are many factors to consider when doing this, including how you join them, what materials you use for flashing, and whether or not you need more support on each side.
The first thing to consider is what kind of roof you are dealing with. A hip construction will be much more straightforward than a gable roof, so if possible, it’s best to try and use the same type of roof on both sides. Make sure all the angles on your hip roofs are exactly 90 degrees before starting your joinery. This will be important later on. You can use this roofing calculator to find the pitch/angle of your roof.
To join two roofs together, you’ll need at least one new square box valley, which you can cut out using tin snips or shears. If there are multiple valleys in between the two roofs, make sure to install another valley in the center of each one where they meet up to help support your new joint. This is what a single hip roof will look like when installed with valley flashing.
How Do You Calculate Roof Valley Angle?
Calculating the slope of a roof valley is not complex with a few simple steps. The angle of a roof valley is most commonly referred to as the “valley pitch.” It is also known as the “roof or slope” or “slope measure.” An online calculator can simplify this process, though, for accuracy, it is recommended to use a handheld calculator.
First, measure five feet from the “high point” of the roof in the valley area. Mark this point with a stake. Next, drive stakes into the ground every one foot toward the ridgeline. At each stake, measure at an angle to find where your slope begins and ends; the distance between markers should be equal. This will help in how to extend roof line.

Can You Extend a Pitched Roof?
You can extend a pitched roof, but it is not recommended. A pitched roof usually has an overhang that extends beyond the rafters and joists on either side of the building. It may be possible to make a gable extension by adding rafter tails to your existing roof and installing new trusses with no overhang, or you may have to install a whole new roof if you want an extension.
