Measuring a roof can be both easy and very difficult. Of course it mostly depends on the roof type, but even a simple roof can be measured in many different ways. Most accurate way would be to climb up on the roof and physically measure it with a tape measure, recording the length of the gables, ridge, and possibly hips / valleys, etc.
If the roof is on a simple, one story ranch type house, with a rather shallow slope, it would be easy to do so. But what if your roof is three stories above the ground and it has a 12 pitch, and best of all it is a slate roof (which is extremely slippery). I would not climb on that roof without a full fall protection system already set up for me, and even then, I would only climb that roof if staging was already installed.
Roof pitch multiplier make your job so much easier, because you can get nearly exact roof measurements by just standing on the ground.
When and who can use Roof Pitch Multiplier
Measuring the roof with pitch multiplier can be be done by both home owners and roofing contractors alike. If you are a homeowner, you can quickly measure your roof to see how much your roofing contractor is charging you per roofing square (100 sq. ft.)
