Bullnose Roof Sheeting Calculator   Enter roof run and angles to calculate sheet dimensions. Drag Sliders to animate.

Total Run
Roof Angle
Curve Radius
Curve Sweep Angle  
?
Adjust Sweep Angle so Roof Angle + Sweep Angle = 90° (curve end is perpendicular)
Straight End
The Curve Radius is the distance from the curve surface (Red) to the centre of the circle it forms. The smaller the radius, the tighter the curve. The Sweep Angle determines the 'length' of the curve, and is the section of the circle that forms the curve.

Roof Angle + Sweep Angle must not exceed 90 °. Check Radius ~ Sweep to show the radius lines to centre and sweep angle.

DON'T BREATH THE DUST 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!

How should we spell it?
