Questions

How accurate are the estimates?

Quantities follow manufacturer coverage rates and standard building practice. Prices start from national averages, so enter your local price for the closest total. Always check with a pro before structural work.

Do I need an account?

No. Every calculator is free and works without signing up. An account is only needed for Pro features like saved projects and PDF quotes.

Can I use metric units?

Yes. Every calculator switches between feet and meters, and the results convert with it.

Does solar still pay off in 2026?

It depends on your electric rate and sunshine. The federal homeowner credit ended in 2025, so payback is longer than it used to be. Our solar calculator shows the numbers with and without incentives.
