💡 How to use: Measure your roof from the ground in feet, then draw the footprint on the grid. Each square = 2 ft.

💡 Tip: For simple gable roofs, draw a rectangle. For L-shapes or complex roofs, add more corners.

1. Pick your grid scale. Choose how many feet each grid square represents. For typical homes, 2 ft/square works well. For large properties, use 5 or 10 ft/square.
2. Measure your roof from the ground. Walk around your house and measure each side with a tape measure or measuring wheel. Sketch the shape on paper first.
3. Click corners on the grid. Start at one corner and click each corner in order. The shape snaps to the grid for clean measurements.
4. Close the shape. After 3+ corners, click your starting point to close the polygon. Area calculates instantly.
5. Get the actual roof surface area. The drawn area is the footprint. Multiply by your pitch factor for true roof surface area.
