How To Measure A Roof With Hips And Valleys

For many people being able to get the right kind of hip roof calculator is very important as knowing how to measure a hip roof is going to be vital to making sure that it turns out well.

How to measure a roof with hips and valleys.

Set up a ladder to allow access to the roof making sure that the feet of the ladder are resting on firm ground and the angle of the ladder to the roof is no less than 35 degrees. To measure a roof start by measuring the length and width of the building s exterior walls and multiplying them to get the area. The heel height overhang and ridge and fascia boards for both roofs will be the same. You can measure the ridge while you are getting the length of the roof.

If you are trying to undertake this all yourself then you should really be looking for the most effective way of working out things like the hip roof square. For trapezoidal roofs measure the bottom edge the top edge also known as the ridge and the distance between the 2 edges. Then calculate the pitch of the roof by placing a level against it angling the level so the bubble is centered and measuring the distance between the end of the level and the roof. The length l times the height h of a triangle is twice its area a2.

Divide the rise by the run the run is 12. To measure the length of a hip roof you will need to hook your measuring tape up to the eave at the ridge rafter run it up all the way up the ridge rafter over the length of the entire ridge and then back down the opposite ridge rafter down to the opposite eave. The blind valley roof can be used to calculate valleys for roofs with unequal slopes. Have a helper hold the bottom of the ladder while you work from it to measure the roof.

In this video i will look at how to calculate the length of the ridge on a simple hip roof. Find the dimensions of each of the roof s faces. Valley roof the valley roof option is used to calculate valleys for 90 degree intersecting roofs with equal slopes and wall plates at the same height. So if you divide your answer of a product of length times height by two you will get the area of a triangle.

This will be the second of a series of three videos if you like t. 1 roof square 100 square feet. The hip and valley factor varies according to the slope of the roof as shown in the table below. Find the square root of the result.

If the roof has a triangular shape stretch your tape measure along the bottom edge then measure from the peak point down to the center of the bottom edge.
