In wildfire situations, the construction of roofs poses the biggest problem for structures due to the materials commonly used and their susceptibility to ignition. Roofs are often the first point of contact for embers carried by wind, which can ignite combustible materials found on or around a roof surface. Specifically, flammable roofing materials such as wood shakes or shingles can catch fire easily, potentially leading to the structure becoming fully involved in flames. Additionally, if the roof structure has gaps or openings, it can allow embers to enter and ignite the interior of the building.

By contrast, while window materials can also contribute to fire spread, particularly if they are single-pane glass or made of flammable materials, roofs generally represent a more extensive surface area that can ignite and spread fire rapidly. Landscaping patterns can influence fire behavior but are often more manageable through proper design and maintenance. Proximity to water sources is essential for firefighting efforts; however, it does not directly affect the vulnerability of the structure itself to burning during a wildfire. Thus, the construction characteristics of the roof make it a critical factor in assessing fire risk during wildfires.
