Estimating Roof Slope and Roof Area

NOTE--We retired MacNail in 2000, and replaced it with Goldenseal construction estimating software. There are still die-hard MacNail users out there, so we keep the manuals online for them! Goldenseal is a complete small-business software package that also includes accounting, job costing and project management features. All roofing quantities in Goldenseal Estimates are calculated, based on a few simple measurements you enter into the Roofing Dimensions screen.

Roof Slope

Type in the slope of the roof, measured in inches of vertical rise per foot of horizontal run. If there is more than one roof slope, type an average slope into the MacNail construction estimating software.

Roof Area

The total area of roof that will get new roof materials is calculated for you. It is measured in squares (100 square feet per square). You can change the calculated value if it seems wrong.

NOTE: Choose Calculate Now from the OPTIONS menu to see the latest calculated value.
