Roof certification is a professional assessment of a roof's condition, typically provided by a licensed roofing contractor. It includes an inspection of the roofing materials, structure, and any potential issues, with an estimate of the remaining lifespan of the roof. Roof certifications are often required by homebuyers, sellers, or insurance companies during real estate transactions to ensure the roof is in good condition and unlikely to cause problems in the near future. If you are buying, selling, or insuring a property, you may need a roof certification to satisfy the requirements of the involved parties.
