Important limitation. This score is not a roof inspection, moisture survey, structural evaluation, warranty opinion, or recommendation to repair or replace. Unsafe conditions, active water entry, structural concerns, loose materials, major storm damage, or suspected hazardous materials require prompt professional review.

Planning estimate only.

Calculator results are conceptual ranges, not bids, guarantees, engineering opinions, or financial advice. Actual requirements depend on verified scope, existing conditions, selections, access, market pricing, design, and approvals.
