What does a roof certification cover?
Usually: an inspection, any repairs needed to get the roof watertight, and a written statement that the roof should remain free of leaks for a stated term. Terms vary by roofer, so read what is and isn't covered (for example, damage from storms or other trades).
Who asks for one?
Buyers and their agents, sometimes lenders, and increasingly insurers looking at older roofs. From January 1, 2028, an independent inspection confirming at least five years of useful roof life will stop an insurer from refusing coverage solely because of roof age (SB 1301).
How is it different from a home inspection?
A general home inspector reports what they see; a roof certification comes from a roofing contractor who repairs and stands behind the roof for the stated period. Make sure the roofer holds a C-39 roofing license (CSLB C-39, license check).
What if the roof can't be certified?
Then replacement or a credit is usually the answer. See new roof before selling.
