Whether you have a garage (vehicle-access) door that is made from a combustible or noncombustible material, you can probably improve its ability to resist an ember attack. Any gaps that exist at the top, sides, and bottom of the door when it is closed are places where embers can easily enter the garage, potentially igniting some of the many combustible materials that are typically stored in a garage. Given the importance of embers, plugging these gaps will significantly improve the ability of your garage door to resist wildfire. You should also make sure that dead leaves and pine needles do not accumulate at the base of a combustible garage door, where burning embers could ignite this debris and pose a more significant risk of igniting the door. And remember to check those areas at the bottom corners where debris (leaves, needles, etc.) may collect and ignite from embers.
