Built on contractor quotes. Not assumptions.
Most online calculators pull from outdated national averages. Ours use regional data. Solar irradiance by state, roofing labor rates by market, material costs updated annually — so your estimate reflects what you'd actually pay.
“We tried five different quoting tools. None gave us regional numbers. So we built our own — with the data contractors actually use.”
