You can draw a shed dormer in just a few seconds with our in app sketching tools!
Using the dormer label in the Facets menu, you can remove attic space and account for overhang sections surrounding the dormer. Following these tips will provide you with more accurate roof measurements, estimates and material orders. Check out the step-by-step below to learn how to DIY!
How to Draw a Shed Dormer, Step-by-Step:
Before You Start - Dormers should be drawn last. Make sure that the main sections of the roof are sketched and that all facets are closed. Select the Facets tab to ensure that the facet the dormer is sitting on is shaded blue, as shown below:
Step 1: Switch to the Draw tab and outline the dormer, labeling with the corresponding line labels.
The majority of shed dormers will consist of Rakes, Eaves, and Pitch Changes, as shown below:
Step 2: Switch to the Facets tab to make sure your dormer facet is enclosed. It should be a darker shade of blue than the facet it's sitting on.
Step 3: Go back to the Draw tab and sketch in the overhang sections. Begin by drawing a line one foot inside where the Pitch Change meets the Rake. Label this line a Wall since it's running parallel with the ground, where you would apply apron flashing.
Step 4: Then draw a Step line from each Wall, stopping one foot inside the Eave. Connect the two Step lines with a Wall where the front of the dormer/window would be located.
Step 5: Switch to the Facets tab. Click on the Dormer label and apply it to the center of the facet. It will turn a green color and say DM above the 0.
This removes the attic space and only accounts for one layer of shingles. The darker blue section around the dormer (between your Step/Rake and Wall/Eave lines) will account for two layers of shingles - those coming up under the overhang and touching the siding, as well as the shingles covering the top of the dormer.
Step 6: Apply your pitch values by selecting Pitch and clicking directly on the rise/run label. Tap on the 0 within the dormer to update the value.
