tallysquare

About

Unlike most free roof calculators that rely on homeowners to provide their own measurements, which often leads to inaccurate guesses, tallysquare uses your address to obtain precise roof area and pitch data directly from Google's Solar API. It then presents a transparent cost range, avoiding any misleading single figures, with a complete itemization covering materials, labor, tear-off, permits, and site access. The service requires no signup or email submission and provides pricing estimates for 2026, broken down by state and material type.
