Hip roof is a roof with a sharp edge or edges from the ridge to the eaves where the two sides meet.
How to find the area of a roof.
Work out the area of the remaining triangular sections.
Hip roof area calculator.
Be sure to find the area of any dormers on your roof as well.
Climb to the top of your roof.
The roof area is simply 114x18x2 plus 30x18x2 giving 5184 square feet which is perfectly adequate for estimating materials.
The calculated area is only an estimation.
Our roof calculator uses base length and base width to find the estimated area.
So in this case for every 12 inches the roof goes across horizontally b while rising 6 inches a there s actually 13 416 inches of roof c.
The base width is the distance from one corner of your roof to the other at its base on the short side of your house.
This isn t as difficult as you might think.
To do that you need to accurately calculate the area of your roof.
In cases where a roof has a complex shape such as in the image to the right measuring the dimensions and areas of each part of the roof to calculate total area will result in a more accurate measurement of area.
You need only a level and a tape measure to find the rise of your roof.
First use your measuring tape to measure 12 inches on your large level and make a mark at the 12 inch line.
Calculating area is easy in two dimensions but nearly all roofs slope up to a peak which adds a third dimension.
Fortunately you don t have to know complicated geometry to factor in the slope of your roof.
Here is the online hip roof area calculator which helps you calculate the hip roof parameters such as roof rise common and hip rafters length and roof area based on width height of roof base and the roof pitch identical for all sides.
Once you know the roof slope multiplier for a particular slope you can use it to find the actual area of any size sloped roof with the same slope.
To calculate the area of your roof first you ll need to calculate the pitch of it.
Next place your ladder against your house at the gable end.
