Measure and mark length on horizontal level to vertical level. Then mark height on vertical level to roof surface, remove levels and measure marked height.
Enter Length and Height measurements and hit Calculate to find roof pitch and angle.
Drag the slider to animate, or with phone or tablet, measure directly from roof surface.
Visit this calculator with Tablet or Phone and lay your device on an angle (the roof) to directly measure Pitch and Angle, and speak results.

If you're cutting blocks, concrete, stone or ANYTHING and there's DUST - DON'T TAKE THE RISK
Don't cut it, or cut it wet so there's NO DUST - Silicosis Sucks
And if you're cutting wet, wear a mask - theres dust in the spray mist too!

What do we think? - They're 2 different things:
A Meter is a device to measure things - like a Volt Meter or a Parking Meter
A Metre is about 3'-3~3/8"
Although diameter and perimeter as measurements - don't seem to fit very well
If the US ever goes Metric, you'll be able to use a Meter to measure Meters - A Meter Meter
(And when we go back to the moon, let's go Metric, ay?)
