How to determine the length of the ridges on a hip roof and how to lay out the wall on a hip roof.
Howto determine where roof ridge lies.
How to measure a roof.
When you reach the top of the roof run your last row long photo 6 and drape the paper over the peak top ridge onto the other side.
If you know the slope x in 12 you want to use for your roof framing design you can use it along with the run r to determine the height of the ridge beam for example if the slope is 4 in 12 and the run is 12 feet the ridge beam height m will be 4 feet.
The walls of a hip roof are laid out from the center of the first common rafter.
The finished ridge beam height z above the top of the wall will be m plus the y height.
First we need to step off the distance to the theoretical center point where the hip meets the ridge.
This free roofing calculator estimates the area of a roof and the amount of materials required to replace or build said roof.
The first common rafter is the one on the end of the ridge.
Determining the ridge beam height.
How to determine hip ridge length and wall layout.
Step 2 determine the surface area of the roof by first measuring the distance along an imaginary horizontal line from the edge of the roof to a spot vertically beneath the highest point.
When you reach the top on the other side of the roof run that paper up and over as well.
The 15 type is most commonly used and one roll of 15 underlayment covers 4 squares.
If the slope is between 3 12 and 4 12 double the amount and put down 2 layers.
How to find a leak in a roof may be the hardest part of fixing a leaky roof.
If you re determined to tackle a roofing job yourself it will be important to calculate the exact square footage of your roof in order to know how much material you ll need.
Finding the actual spot where the roof leaks is difficult because water can enter the roof in one place and run down to another before it starts soaking into the ceiling.
As a reminder please don t forget to add height of rafter thickness of roofing material and ridge vent to the number that you ll get using our calculator.

If the same house had a central roof ridge dividing the roof into two sloping areas each would cover 300 square feet or half the house.
Take the run of the main roof 9 feet and using your square and the pitch of the hip in relationship to the main roof 8 inches and 15 5 8 inches step off this distance in the conventional manner.
