# Roofing Guides for California Homeowners

Roofing guides for California homeowners: plain answers to the questions that decide what goes on your roof, from the rules to the materials and the timing.

**These roofing guides answer the California-specific questions homeowners ask before a re-roof**: whether the Title 24 cool-roof rule applies, when a Class A fire-rated roof is required, what a permit involves, how tile underlayment is replaced, how metal compares with shingles, and whether to replace the roof before solar. Each one cites the code or public source it relies on, with the date it was read.
