Tile is one of the longest-lasting roofs you can buy — but it was engineered for dry, sunbelt climates, and Vancouver and Portland throw the opposite at it: relentless rain, moss, and freeze-thaw cycles.
Here's what most homeowners miss: on a tile roof, the tile rarely fails first — the underlayment underneath does. Skip proper flashing or ventilation and leaks show up two ceilings from the real damage. Moss makes it worse, cracking tile and trapping moisture against fasteners.
You don't need a roofer who "also does tile." You need one who treats it as a specialty.
