A roof that has many hips and valleys is said to be cut-up.

What that means is that the roofing contractor will have to cut the roofing panels to fit as opposed to just installing the panels as they come from the supplier.

Other roof features that affect labor include the amount of flashing a roofer has to use if there are chimneys, skylights, or the like.Rotten plywood that needs to be replaced, and old shingles that can’t be installed over will also affect the price of a new metal roof. The best thing to do is to have a roofing contractor come out to give you an estimate and to see what he has to say about what it would take to install a new metal roof.
