To keep the soffit level on an unequal slope roof with an equal overhang, it is essential to adjust the wall under the major roof based on the height difference created by the varying slopes. This is accomplished by raising the wall under the major roof by the difference in rise of the roofs over the run of the overhang. By doing this, the overhang remains uniform, ensuring that the soffit fitting is consistent across the entire structure, which not only contributes to the aesthetic appeal but also to the structural integrity and drainage of the roof system.

In achieving this uniformity, adjusting the wall under the major roof aligns the height of the major roof’s eaves to match the minor roof, thus maintaining a consistent soffit plane and the overall architectural design. This technique is fundamental in construction, especially in scenarios involving unequal slopes, where precise measurements and adjustments prevent potential issues with drainage or visual discrepancies.
