Here’s a step-by-step guide to measuring with blueprints:
- Open the app and select “Measure Your Roof.”
- Select “Sketch My Roof.”
- Retrieve your blueprint image by tapping “Load,” then selecting the source of the file, i.e., your email, Dropbox, etc.
- Select the blueprint you wish to measure.
- Roof Type
- Roof Materials
- Roof Ridge Covering
- Roof Ventilation
- Roof Overhang
- Roof Pitch
While it’s possible to create your own roof blueprint using software or online tools, this is a task that is often best left to the pros – especially for new roof construction.
Many roof designers and architects now create roof plans in 3-D. 3-D blueprints will provide a complete roof visualization that includes bridges, rakes, eaves, intersections, and runoff calculations for inclement weather conditions. A roof blueprint can also be used to diagram proper venting to protect a home or business from moisture buildup that can lead to mold growth.
The formula to find the slope of a roof is:
Slope = Total Rise/Total Run
Roof Slope = Rise (in inches)/12 (inches per foot of run)
Roof Slope = (Total Rise/Total Run) x 12
