No one /needs/ a flat roof ;-)


But is it the wrong time of year to be doing this? Will having it done
in cold weather shorten the life time of the new roof? I am thinking of
expansion and contraction throughout the year.

I can't see it making any real difference to the finished product. Might
make it more difficult to install if it's wet though.
