You really dont get it do you , it IS a pressing issue that needs to be
addressed. You cant sell it like that. And soon you WILL have rot.

After reading the info about venting attic, I gradually become
convinced that I need to greatly improve the ventilation of my roof
(there is no ventilation currently). In other words, what the roofers
proposed will not work because they only want to replace the roof
cover, but not improving the ventilation. They probably were misled by
the vent holes in the gable ends (they look OK outside; but actually
they were sealed in inside; now they become a part of the wall).
Therefore, they may not realize that the roof is not being vented in
anyway.

I will call them back to make clear to them that the roof is not
currently being vented, and see if they may come up with a different
proposal.

I will also ask other general remodeling contracter to see if
rebuilding the roof (by increasing the pitch to create a real attic)
is feasible and for how much.

Thanks.
