Thorne v. White

White (plaintiff) contracted with Thorne (defendant) to install a new 4-ply roof over White's existing roof for $225, but Thorne began the work and then abandoned the project; White hired Koons Roofing Company to finish it for $582.26, though the Koons contract called for a 5-ply roof and required entirely replacing the old roof rather than simply covering it, increasing the cost. White sued Thorne for $357.26 -- the full difference between the two contract prices -- and the trial court ruled in his favor; Thorne appealed.
