Shingle Roof Replacement in Glendale

It is allowed up to a limit and it is usually the wrong call on a roof this age. An overlay hides the deck, adds weight, and sits on a surface that is no longer flat, which shortens the life of the new covering. Check the layer count at the rake before anyone quotes you an overlay.

Look at the field rather than the failure. Composition here tends to go across a whole slope at once -- granules gone, tabs brittle, seal lines broken -- rather than in patches. A bald section on an otherwise sound slope is a repair; a whole slope like that is a replacement.

In Los Angeles County most replacements are estimated at $10,000 to $25,000. Composition shingle runs $7 to $11 per square foot here and clay tile $15 to $25. Glendale sits at the tile end of that more often than most of the county, which is why the relay question matters so much locally.

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.

For composition on an average house, yes, and you should get another quote. For a full clay tile replacement in Los Angeles it is a normal number -- tile runs $15 to $25 per square foot, so $30,000 to $60,000 is the range. The question worth asking first is whether you need a replacement at all, because a relay of your existing tile is $8,000 to $22,000.
