The first of which is that you don t even have to go up on the roof.
Roof measuring worksheet.
How to calculate your roof square footage first measure the length and width of each surface on the roof then multiply these values to get the square footage of that surface.
What is a roofing estimate.
It could be useful to make rough freehand sketches of measured areas for later reference.
The sketch is a dynamic fully editable drawing that you can customize with inspection photos and notes and use to create an estimate in roofsnap.
Picture of the roof with its materials to be used either concrete or fancy should be mentioned and the experience that you have attained in the field.
This can make it even safer to do your measuring and it also removes a level of guessing to your calculation.
If you have a complex roof shape breakdown the plane to make a two dimensional figure.
In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches.
And do the same for the second side.
It is often compared to slope but is not exactly the same.
Make sure to document the number of chimneys skylights or other obstructions and include dormers in your measurements.
Measuring the slope from the surface of the roof.
For instance a 7 12 roof pitch means that the roof rises 7 inches.
To measure the area of the roof use your measuring tool and start from a tip ending to another tip of one side.
A roofing estimate is a process that lets a contractor and a client know what types of materials will be needed for a project.
There are many great benefits to using google earth to measure your roof but nothing is as good as using diy s satellite roof measurement.

The length l times the height h of a triangle is twice its area a2.
You can order roof measurements from roofsnap and our sketchos technicians will create the measurement diagram for you.
Before taking any measurements you must first confirm that it s safe to walk on your roof.
1 roof square 100 square feet.
We ll use satellite imagery and trigonometry to calculate your roof s measurements.
Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.
Take the measurement of the vertical distance from the rafter to the level.
So if you divide your answer of a product of length times height by two you will get the area of a triangle.
Give each area a recognizable name so it makes sense when you look at it a few days from now.
It lists the scheduled.
