tallysquare とは？

Most free roof calculators ask you to measure your own roof yourself — which most homeowners can't do accurately, so the estimate is only as good as a guess. tallysquare pulls real roof area and pitch from Google's Solar API using just your address, then shows a cost range (never one fake-precise number) with the full breakdown: materials, labor, tear-off, permits, access. No signup, no email gate. 2026 pricing by state and material.
