We have used monier sentry classic roof tiles for sale. these tiles are no longer made in california so if they match your roof, get some extras just in case.
the tiles weigh about 10 pounds each so keep that in mind for rafter / truss loads and for transportation.
• flat tiles $0.50 ($0.25 in quantities of 100 or more)
• rakes $2.00
• ridges $1.50

over 2500 flat tiles available, very limited number of rakes and ridges.
ridges will need to be repainted. all can be painted to match existing tiles.
pictures of the rakes and ridges are available upon request.
