Does San Rafael really require my wood shake roof to be replaced?
Yes. Ordinance 2009, adopted by the City Council on May 16, 2022, amended the city's building code so that every roof covering that is not at least Class A must be replaced with a Class A covering by May 31, 2027. The city says financial assistance may be available and asks owners to contact Wildfire Prevention in the Fire Department.
Can I treat my shakes with a fire retardant instead of replacing them?
The city's report behind the ordinance found that spray-on and brush-on treatments lose their fire resistance as they leach and weather, and that pressure-treated shakes reach Class A only over a solid underlayment, with no later test to confirm the treatment remains. The ordinance was written around replacing wood roofs with a Class A covering; ask the Building Division before relying on any treatment.
My San Rafael house isn't in the wildland-urban interface. Does the Class A rule still apply?
Yes. San Rafael's Class A requirement covers roof coverings throughout the city, not only in mapped fire areas, and the city has extended other requirements that once applied only to WUI parcels to every parcel. A repair or a partial re-roof needs Class A material wherever the house is.
How many layers of roofing are allowed on a San Rafael house?
The city's online re-roof permit allows only one overlay. If the roof already carries a layer over the original, expect a tear-off before the new Class A covering goes on. Removing and replacing rooftop equipment also takes the job out of the simple online minor permit and into a fuller review.
Do I need a permit to replace my roof in San Rafael?
Yes. A residential re-roof is a minor permit you can apply for online, with conditions on overlays, roof drains, attic ventilation and the stated value of the work. Since January 1, 2023, minor permits have been valid for 180 days, so plan to have the roof finaled within that window.
