I received the following note from Eric Coons regarding cedar shingles:
I am writing in response to your knowledge of shingles. You have none!! I have been in the roofing industry for over 12 years and am now a Cedar shake and shingle broker with extensive knowledge of cedar roofing. You said that asphalt shingles are more durable than cedar shingles. You could not be any further from the truth. Cedar shingles will stand up to every different type of weather better than any other kind of roofing material on the market today. Cedar has undergone extensive testing for wind and hail ratings, not to mention fire rated cedar shakes and shingles. Homeowners have been able to obtain an class A fire rating with Fire Treated cedar shakes & shingles for quite a long time now. They can carry a hail rating of class 4 if required in specific areas. I sell my products in mostly the mid western United States and when hail storms do happen the only roofs that survive are Cedar shake roofs. The asphalt roofs are totaled out by the insurance companies!
Cedar is also the only product that has its own insulation properties, which will keep your house cooler in the summer and warmer in the winter thus reducing the your heating and cooling costs. I personally have cedar shakes on my barn that have been there for 45 years and still do not leak. If that alone does not tell you that cedar is not durable I don't know what will. Good luck with that two tone asphalt roof it should last you about 8 to 10 years.
I don't suppose that last bit about "two-tone asphalt" was meant to be sarcastic, but I will say that my personal experience with asphalt is closer to 20 years.
