The vertical line to follow for the correct installation


An easy way to find a vertical line is to use an asphalt shingle and your eyes.  Adequate on small gazebos. On homes, you will need to find the exact 90 degrees angle as small differences will show over distances. You will need to use a right-angle triangle calculator to find the measurements for this.  Snap a second chalk line at 165mm  and you have your vertical lines to follow.
