InspectorD, the roofing God, handyguys, CraigFL
Perhaps this photograph will explain my situation a little more. InspectorD's advice to not replace since it is not leaking is likely good advice.
In my earlier posts I described my flat (much flatter than this) front porch roof. This link is too a photograph of the roof over the bay window which is the same construction and in similar shape. This is metal with black material over it.
Again no leaks. I did not like the contractor proposal to shingle this and the front porch for nearly $1200 and thought that covering with a sealant for $550 wasn't such a good idea either, because I think that I could do it myself.
What appeals to me is yanking the metal roof off and having a roofer put a new metal roof on. Maybe that doesn't save much and maybe it is hard to do. Neither contractor suggested that drastic a step though, but I do like the idea of having the opportunity to look at the wood underneath and determining if replace of any part of it is needed.
