Roof pitch, expressed as a ratio of rise over run (like 6:12), is crucial for proper water drainage, material selection, and structural integrity. A roof's pitch affects everything from installation costs to long-term maintenance requirements.
| Pitch Range | Best Uses |
|---|---|
| 2:12 to 4:12 | Commercial buildings, porches, sheds |
| 4:12 to 6:12 | Ranch homes, modern designs |
| 6:12 to 9:12 | Traditional residential homes |
| 9:12 and steeper | Victorian, Gothic, Alpine styles |
Always measure roof pitch from a secure position, preferably from inside the attic using a level and tape measure. For exterior measurements, consider using a pitch gauge tool and following proper safety protocols.
