Hi tex, The 3/4 makes sense now. The clay tiles are they the real McCoy or the manufactured ones?
Get three bids to compare. I don't know the roof pitch ans Sq ft.
A bit confusing here.
This bid was $4500 labor for 3 days effort,
is that the guessed time to install?
I don't know the size of roof here but it sounds OK to a point, I would not allow staples to hold sheeting down ever.
Get 2 more bids to check price here.
The other thing I see missing here is roof felt and what pound. Code here is 30lb felt. Old days 15lb was fine I do wonder of overkill. I think its more for safety walking the roof shingling and not tearing as quick and loose footing. Other then that 15# has worked fine for as long as I can remember
