Easy Methods To Tie Two Parallel & Different Gable Roofs Together
A gable roof is extremely simple geometrically, however, when two gable roof lines intersect or lies across each other, the geometry gets more complicated. The framing that is needed at the intersection of two roof lines is easy to understand, provided you are familiar with the basic framing components of a typical gable roof. If you are looking to tie two gable roofs together, then you can go through the below-mentioned methods carefully & achieve the desired result of your work:
Method 1: Ridges
- The ridge board is the parallel & straight framing member that usually defines the roofline in a gable roof. Ridges generally stretches & elongates from one gable end to the other at the top of the roof. In a gable roof having a level of quality or attainment, the ridge board does not provide structural support for the roof & is used essentially as a nailing surface when it comes to the upper ends of the rafters.
- When two gable roof lines lie across each other, the ridge boards of each roof line touch or join. The method for joining the ridge boards varies in accordance with the local building codes, however, when nonbearing ridges lie across each other, the intersection generally needs no special consideration.
Method 2: Common Rafters
- Rafters are regarded as the sloping members that usually run from the roof ridge down to the peaks of the walls. Rafters generally function as the primary support for the roof, & they move the weight load of the roof downward to the walls and, finally, the ground.
- Common rafters are the full-length rafters that stretch or elongate completely from the ridge to the exterior walls of the building. The upper ends of the rafters are generally nailed to the ridge board. However, when there is no ridge board, then the upper ends of the rafters butt in opposition to each other at the peak. In this case, a gusset plate is often used in order to reinforce the connection.
Method 3: Valley Rafters And Valley Jacks
- The intersection where the two gable roof lines meet form inside corners, usually known as valleys. The crosswise rafter that runs from the intersection of the ridges down to the peak of the walls at the inside corner is known as a valley rafter.
- Shorter rafters that generally run from the ridges to the valley rafters are known as valley jacks. The valley jacks moves or transfers the roof's weight load from the ridges to the valley rafters, transmitting the load downward to the walls.
Method 4: Structural Ridges
- In conventional roof framing, the rafters carry or support the weight of the roof and the ridge board does not carry out or perform a structural purpose. However, in some framing designs, the ridge must hold up some of the roof's load; in these cases, you can replace the ridge board with a structural ridge beam that is supported by columns at the gable ends or in the interior of the building. A ridge beam that lies across another ridge line must be supported at the intersection.
