Shingle Roof Replacement in San Gabriel: what actually fails

An overlay is a worse idea in old San Gabriel than almost anywhere nearby, because of what is underneath. On skip sheathing there is nothing solid to nail into between the boards, so a second layer ends up with loose courses in its first windy season. Tear off, see the deck, then decide.

The variable that decides a shingle price here is what is under it. On the oldest El Monte stock the deck can be skip sheathing -- spaced boards laid for wood shake -- which a modern covering cannot be nailed into reliably and which has to be overlaid or replaced first. On a post-war bungalow it is board sheathing, and on recent infill it is plywood.

  • Which deck you have, because the oldest stock is skip sheathing
  • Whether the tile profile is still manufactured
  • The junction between the original roof and any addition
  • Whether an overlay is even viable on what is up there

What it costs

Shingle roof replacement cost in San Gabriel

Composition runs $7 to $11 per square foot in Los Angeles County against roughly $4 nationally, which is why an online calculator never matches a local quote. On the housing here the number that actually moves it is what the old covering is sitting on, and there are three possible answers in this city depending on when the house was built. The deck decides the price on the older streets. Skip sheathing has to be overlaid before a modern covering can go on it, and that is a real cost a curbside quote will not contain -- which is how two neighboring houses end up thousands apart on the same roof.

01

Three decks, three prices

Skip sheathing on the earliest stock, board sheathing on the post-war bungalows, plywood on recent infill. Only the third takes a modern covering without being overlaid first, and none of them is visible from the street.

02

Layer count is a hard limit, not a preference

Two coverings is the practical ceiling. If you are already at two, the next job is a tear-off whatever anybody quotes -- so a cheap overlay price on a twice-covered roof is not a price, it is a misunderstanding.

03

What makes it cheaper

A simple gable, room to get a conveyor to the roof, and a deck that needs nothing. On a straightforward valley-floor house this is the most predictable job on the list.

Roofs in San Gabriel, and what that means for shingle roof replacement

San Gabriel has the oldest building stock covered on this site after El Monte itself, and on the older houses the deck is the variable that decides everything. Skip sheathing laid for wood shake cannot take a modern covering until it is overlaid, and that is a real cost a quote written from the street will not contain.

Roof Replacement in San Gabriel

Before you replace

Which roof is finished, and which one just looks it

On most parcels here there is more than one answer, and the expensive mistake is replacing the wrong one.

01

The test is the field, not the failure

Look away from the leak. If the covering across the rest of the slope still has granules, still lies flat and is not brittle, that roof has life in it. A failed flashing, a split upstand or a slipped course is a repair costing hundreds -- and each is routinely presented as proof the whole roof is done.

02

On tile the gap is the widest of all

A tile roof quoted at $30,000 to $60,000 for replacement is very often an $8,000 to $22,000 lift and relay, because the tile is fine and only the felt beneath it has failed.

03

Damp is not always water from outside

In a converted garage, damp that is worse in dry weather is condensation, not a leak -- a room built under a roof that was never insulated or ventilated. Replacing that roof without fixing that is money spent on the wrong problem.

The questions this job turns on, answered up front.

Questions

What homeowners here ask

Why is the local price double what the calculator said?

Because the calculator is national. Composition is about $8.50 per square foot here against roughly $4 nationally. A local quote that does match a national average is usually missing the tear-off, the sheathing allowance, or both.

Half the slope looks bald. Patch or replace that slope?

Be careful what that is telling you. Composition here tends to finish across a whole slope at once rather than in patches, so a bald section usually means the slope is done rather than damaged. We will tell you which one you have instead of selling a patch that fails.

Will I be forced into an expensive cool roof?

Not on a pitched roof here. The steep-slope cool-roof requirement applies in Title 24 climate zones 10 to 15, and El Monte is in zone 9. Low slope is different -- an aged SRI of 75 applies in all sixteen zones once you replace 50% or more of the roof area in a rolling year. Anyone telling you a pitched El Monte roof must be a cool roof is quoting the wrong zone.

How long will the work take?

Two to four days per structure once it starts: tear-off and dry-in on day one, covering after. Tile takes longer than composition, and a sectional relay on a tight lot longer again. Weather moves it, and we will not dry-in a roof we cannot finish.

How much does a roof replacement cost here?

A house in Los Angeles County is estimated at $10,000 to $25,000 for most jobs. Composition runs $7 to $11 per square foot locally against about $4 nationally, which is why online calculators read low. The inspection is free and the quote is written, because pitch, access, covering and what the old roof was hiding all move it.
