Tile Roof Underlayment Replacement

In Arizona, the tile isn't the waterproofing — the underlayment beneath it is. When that layer ages out, replacing it stops leaks without replacing the whole roof.

Is your tile roof leaking even though the tiles look fine? In Arizona tile systems, the actual waterproofing is the underlayment beneath the tile — not the tile itself. Tile sheds water to the underlayment, and that underlayment typically lasts 20–30 years before Arizona heat and monsoons break it down. Roof Pros Arizona replaces the underlayment while preserving and reusing your existing tiles — a mid-life service that stops leaks at a fraction of full replacement cost.
