Hips and valleys roofing.

The hip and valley roofing shear is the optimal metal roofing tool for cutting hips and valleys on your metal roof panels. This type of roof is also called broken back hip and valley roof because the main hips are intconeected by the rafter of gables on one side and the rafter of the valley on the other. The hip and valley factor varies according to the slope of the roof as shown in the table below. A dutch hip roof is a combination of both the hip roof and gable roof features.

Every common rafter is the same length brown and each hip rafter is the same length too red. The green arrows above show every side is equal we ll assume 2 metres for this example. The hips are in red common rafters yellow and for hips to work on a square roof like above each member is equal. A hip and valley roof may be part of an irregular structure.

You can see in our roof valley photo left that there has been a history of. Hip roofs are thus much more resistant to wind damage than gable roofs. It is sometimes also referred to as a dutch gable roof precisely because it contains both roof style features. The gable portion of a dutch hip roof is usually placed at the end of the roof ridge and sits on top of the plane of the hip roof.

Today where laminate products are the overwhelming shingle of choice specific shingles are manufactured for the hips and ridges. A hip roof is self bracing requiring less diagonal bracing than a gable roof. Overlap metal roof valley sections by 12 inches and seal the lap with a flexible sealant such as polyurethane or butyl on roofs shallower than 5 12. Ideal for shearing heavy gauge exposed fastener panels with the ability to shear straight at 90 degrees and up to a 9 12 valley.

A hip roof on a varied plan h denotes a hip v denotes a valley. For any roof slope expressed as x in 12 rise in run the hip and valley factor is determined by finding the square root of rise run 2. Where two roof valleys meet for example above a gable dormer a soldered joint is likely to break from the movement. Such buildings may have more than four hips in the roofs and they form valleys at the inside corners.

Eliminates burred edges and flying metal.
