The roof area is simply 114x18x2 plus 30x18x2 giving 5184 square feet which is perfectly adequate for estimating materials.
Measure roof area.
Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.
First use your measuring tape to measure 12 inches on your large level and make a mark at the 12 inch line.
To accurately calculate the area of your roof you must first determine its slope or pitch.
Climb to the top of your roof.
A 12 in 12 pitch is a.
So you re thinking of reroofing the house yourself and want an estimate for how much roofing material you.
The roof area for a hip end is the same as for a gable end the intersection is equivalent to a hip slightly conservative so there is usually no need to consider triangles when measuring a roof.
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 calculated area is only an estimation.
To measure a roof start by measuring the length and width of the building s exterior walls and multiplying them to get the area.
Next place your ladder against your house at the gable end.
