3 12 roof pitch – In construction terms, a roof with a 3-12 pitch, three meters of vertical rise, each 12 meters long, or roof run. A 3-12 ceiling equal to 14.04 degrees and is a regular pitch in southern climates. Roof pitch Varieties, in geometry terms, a roof pitch of the slope. When it comes to architecture, a roof pitch varies between a low pitch of 9.46 degrees (2-12 pitch) and a steep climb of 45 degrees (12-12 roof slope).
3-12 ceiling calculate pitch, you can determine if your 3 12 roof pitch with a tape measure and a 12-inch spirit. Place the 12-inch spirit level horizontally across the roof so that it is parallel to the ground below, and the far end touches the ceiling. Check that the bubble level is in the middle position, indicating that the center level. Measuring tape in inches will equal the second number in the plan. For example, if the measurement is 3 inches, your pitch 12-3, because the level is 12 inches and it grew 3 inches.
The 3-12 pitch susceptible to winter problem because the slope is less steep and therefore more accumulated snow and ice. You will need a ladder to get safe access to the roof to measure the pitch. Remember that you will not have to walk the entire length of the roof, but you will need to work with at least 12 inches of the roof driving. A 3 12 roof pitch is safe to cross, but if your roof is unstable or has shingles, try to measure from inside the home.
