Summary: asbestos shingles have much lower fire danger

I would strongly recommend that you not replace the roof with cedar
(or any other wood) shingles--there is a very high danger of fire
with a wood roof which can be greatly reduced by using asphalt or
asbestos shingles.  The danger arises not so much from your house
catching fire and the roof burning but from a neighboring fire spreading
to your house when hot embers land on your roof.  Even in non-forested
areas this can be quite a problem.

When I last replaced my roof, I used 15 year guarantee materials.  The
roof is actually expected to last a little longer than the guarantee time
and the installer told us 15 year lasted about 20 and 25 year about 35.
So, I was 30 at the time and in 20 years would be 50; in 35 years I would
be 65 and maybe retired.  Better I should have to replace the roof a second
time when I was 50 and still gainfully employed than have to do it when I was
near retirement.
