Things Could Be Worse

OK Homeowners, here's a quick poll for you. What is the worst time to re-roof your house?
a) When it is on the market
b) When it is 15F
c) During the snowiest winter for several years
d) During a "dangerous winds" advisory

If your answer is all of the above, you must be our poor neighbor whose house has been in the process of being re-roofed since last year and still isn't done. Feel better about your renovations now?
