Ridge Runs Into A Higher Roof

Rob haddock a metal roof consultant and director of the metal roof advisory group responds.

Ridge runs into a higher roof.

But here it will be different since the hip rafter doesn t lie at 45 degrees to the commons. The ridge board runs the length of the building and provides support for the tops of the rafters helping the whole roof structure work together as a system. Where the porch roof extended over the shed roof we installed a 2x6 ridge that ran from the top of the dropped structural ridge to the apex of the sleepers. Part of a roof s frame a ridge board runs horizontally along the peak of a sloped roof.

The ridge board must be set as perfectly as possible so take your time and use careful measurements. Essentially the spine of a conventional stick framed roof the ridge board is sandwiched between the meeting ends of the roof rafters. The dutch gable hip roof is a hybrid of a gable and hip type of roof. This style also improves the look of the roof providing a more unique and interesting design than the very common simple hip roof.

To scribe the angle we placed a length of stock on top of the rafter peaks and leveled it across using a scrap block to trace the angle. Roof ridge vents and other forms of roofing ventilation work better when homes are in colder climates. For example in an equal hip roof with an 8 12 pitch the pitch of the hip rafter would be 8 17. Expect the installation of a ridge vent to run about 500 on average if you re not touching the rest of the roof.

With this design the ridge beam bears much more load weight than the ridge board on a standard stick framed roof. A roofing contractor can install the ridge and soffit vents that a properly ventilated roof should have. In a hip roof with equal pitches the unit run of a hip or valley rafter is 17 inches for every 12 inches of run in the main roof. A full or partial gable can be found at the end of the ridge in the roof allowing for a greater amount of internal roof space.

Complete replacement may be over 1 000 on some roofing types. A timber frame roof has rafters and a ridge beam as with stick framing but the ridge is a large structural beam that the rafters sit on top of or sometimes fit into notches cut into the beam. Face it towards the area of the roof that gets warm and run it whenever there is any snow on the roof. The culture of fastening through the ridge crest or through the valley of the metal roof profile seems to vary in the continental u s.

It doesn t work well in warmer climates. The ridge is the peak where two sloped roof sections meet.
