Tile Roof Replacement in Montrose

Because the leak is under it. Clay and concrete tile outlast the felt beneath them by decades, so the underlayment tears and goes brittle while the tile field above still looks new from the street. That is the commonest tile failure in Glendale and it is not visible from the ground.

Not from a supplier -- that profile has not been made for generations and the color variation across ninety years of weathering cannot be matched from a pallet. What works is salvaging your own: a relay puts the original tile back, and where some has to be replaced the sound pieces go on the street elevation.

It is a real rule and it is not California's. Several states apply a 25% threshold, above which a repaired roof has to be brought up to current code. California uses 50%: replace more than half the total roof area within any one-year period and the whole roof has to comply. If you have read about the 25% rule, that is why it does not match what a Glendale contractor tells you.

If the property is identified as historic, yes -- roof form and roof cladding are explicitly within scope. The part that catches people out is the order: a Design Review Exemption has to be approved BEFORE a building permit application will be accepted, not at the same time. Check your own address with the City of Glendale before anyone specifies a covering.

Not automatically. Age is a prompt to look, not a verdict. Composition at twenty years is usually near the end; clay tile at twenty years has decades left in the tile even if the felt underneath is finished. That distinction is most of the roofing decisions made in this city, and it is settled by a survey rather than by the calendar.
