Interactive FAQ
What if my roof has a complex shape?
For complex roof shapes, you may need to divide the roof into simpler shapes (like rectangles) and calculate each section separately. Then, sum up the areas of all sections.
How does roof size affect energy efficiency?
A larger roof provides more surface area for solar panels or insulation, which can improve energy efficiency. However, it also exposes more of your home to heat gain or loss.
