Well due to an ice storm way back there is a hole in the sun room. Did
not see it nor did it leak till I blew the debris off.

The quote for replacing the shingles and sheathing and using ice and

That seems down right good to me.

I know it will clash with the rest of the house, but it could be a good start for when you are going to have to have your shingles replaced. Have them use a metal roof. They are guaranteed for 50yrs and, unless you have very large 4"+ hail, you do not have to worry about it. The cost is not much more, and in year of service life, less than shingles. IF you do go that route, sometime in the future, when they do the rest of the house, make sure they use 1x4's for the mounts and not 2x4's, for the simple reason squirrels can get in between the metal and your existing room with 2x4's. Do not, under any circumstances allow them to put the metal flat on the roof, it will the underlayment to sweat, which destroys it.
