Making one or two simple straightline measurements from the ground along with clever use of a folding rule or other methods discussed in this article series can give us accurate measurements of the church roof dimensions, slope, and area. The attractive New Zealand slate roof shown here protects the beloved Catholic Church of St Werenfried in Waihi Village, at the edge of southern Lake Tekapo, in New Zealand (South Island). We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need. This article series gives clear examples just about every possible way to figure out any or all roof dimensions and measurements expressing the roof area, width, length, slope, rise, run, and unit rise in inches per foot. This article shows how simple measurements can give the roof area without having to walk on the roof surface. We include on-roof measurements, roof measurements or estimates that can be made from ground level, and several neat tricks using a folding ruler to measure roof angle or slope. Here we describe various methods for measuring all roof data: roof slope or pitch, rise, run, area, and other features.
