No one can deny that cedar shakes and shingles burn; for that matter, so do asphalt fiberglass shingles. Since over 95% of all residential fires originate in the interior of the home, it is logical to relate "Safety" to the reduction of interior fires. However, "Safety" begins inside the home where carelessness, smoking, over-taxed electrical and heating equipment, plus other causes provide the true danger to the homeowner. It seems far more logical to provide fire-resistant furnishings (carpets, drapes, furniture, etc.) than fire retardant exterior building materials, such as various roofing materials.
Wood shake and shingle roofs, which are normally installed over "spaced" sheathing, "self ventilate" in the event of an interior fire, which is where 95 percent of all home fires originate.
Asphalt fiberglass roofing, on the other hand, is applied over "solid" decking, which severely restricts the ventilation of toxic gases and smoke to the outside. Loss of life in fires is often the result of suffocation from super heated smoke and gas, not the fire itself. It is little consolation to the homeowner that his roof was saved if he died from smoke inhalation.
National figures are not available, but an intensive study was made in Dallas during a 30-month period. During that time, no one died in a home with wood roofing. However, 88 people lost their lives in homes with asphalt shingled roofs.
