How Much Does It Cost to Replace Underlayment on a Tile Roof?
Replacing the underlayment on a tile roof typically costs somewhere between $4 and $8 per square foot, or roughly $400 to $800 per roofing square (100 square feet), though the final number depends heavily on roof pitch, accessibility, tile type, and local labor rates. For an average home with 2,000 to 3,000 square feet of roof area, total underlayment replacement generally runs from about $8,000 to $24,000 — a wide range that's worth understanding in more detail before getting quotes.
