Underlayment matters more than the shingle

On tile and metal roofs, the underlayment is what actually keeps water out.

Tile sheds most water — but anything that gets through has to land on the underlayment. Felt-paper underlayments fail in 15–20 years. Synthetic and self-adhered underlayments go 30–50.

When we lift tiles to replace underlayment, we can usually reuse 90%+ of the tile.

Cheaping out on underlayment is the single most common mistake we see on otherwise-nice tile installs. The labor to redo it later is the same; the material upgrade is a few hundred bucks.

What people say after James walks their roof

Three roofers wanted $32k after the June hailstorm. Roof Doctor NM walked the roof, took 84 photos, and said the hail was cosmetic. Saved me from a fraudulent claim.

Under contract on a Corrales house. The pre-purchase report caught two hidden layers the seller's disclosure missed. Got an $18k credit at closing.

Bid review flagged that the 'lifetime warranty' voided if we used the wrong underlayment — which the contractor had specced. Renegotiated the whole scope.
