Failed underlayment under intact tile
Why it happens here
Most Woodbridge tile roofs are 30 to 50 years old. The tile can last 50 to 100 years, but the underlayment beneath it dries out and cracks after 20 to 30 years. Once it fails, water gets through even though the tile looks fine from the ground.
Our approach
We inspect underlayment condition on every roof, not just the tile. If the tile is sound, we recommend a lift and relay instead of a full replacement. That saves money and adds decades of life to the roof.
