The danger of a house fire may be one valid reason to make sure your roof stands a good chance against fire. Fire-rated metal and asphalt roofing materials, for instance, make good replacements for
re roofing in Palo Alto homes. Homes with slate roofs are often reported to have been spared in neighborhood conflagrations where fire leaps from roof to roof.
This is why it is important to check the ratings of the roofing materials to learn the level of protection you can expect from the material. Class A roofing has the highest fire resistance rating as it can withstand even severe exposure to fire, while class B can tolerate moderate exposure to fire. Class C materials, with only minimal exposure, can be defenseless against fire.
