Shingle Roof Replacement in El Monte from $7. Composition on a century of different decks. Free inspection and a written quote.
What is under the shingle decides the price, and in the oldest settlement in the valley that could be almost anything. Skip sheathing on the earliest stock, board sheathing on the post-war bungalows, plywood on recent infill -- three different decks, three different prices, and none of them visible from the street.
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.



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. Two things move an El Monte quote more than the roof does: how many structures are being counted, and whether there is anywhere to work. A house built out to the line with no side yard costs more to strip than the same roof on an open lot, and a quote that does not say which structures it covers cannot be compared with another one.
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.
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.
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.
Two things recur on nearly every parcel. There is almost never only one roof -- a house, a detached garage, a rear addition and a patio cover is the normal count -- and an increasing share of those garages now have somebody living under them, which changes the roof from a rain question into a ventilation one.
El Monte is the oldest settlement in the San Gabriel Valley, which means its housing spans more building eras than almost anywhere else in the region.
That is not a detail, it is thousands of dollars, and it cannot be established from the street. Any quote that has not said which deck you have has not established its own cost.
On most parcels here there is more than one answer, and the expensive mistake is replacing the wrong one.
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.
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.
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.
A single figure on an El Monte quote quietly decides what it covers, and on most parcels here the honest answer is four roofs: the house, a detached garage, a rear addition and a patio cover.
No replacement parking is required to convert a garage here, and a valid application gets a 60-day review -- which in the valley's densest city has produced a lot of conversions.
The constraint on a tile relay here is space, not skill.
There is more low slope per property here than in most of the valley, and the reason is the added-on structures.
Separate structures have separate 50% tests, and on an El Monte parcel that is unusually useful because so many have three or four.
A different city, with a different department.
Room to work, which makes a tile relay cheaper.
Same stock, more space, its own conversion rules.
Mature canopy. Debris in every valley.
Old stock and skip sheathing. Check the deck.
Hillside split levels and short low-slope links.
Small apartment blocks and the logistics they bring.
The questions this job turns on, answered up front.
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.
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.
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.
In this city the commonest reason is that they are not counting the same structures -- one included the detached garage and the addition, the other priced the house. After that it is a tear-off versus an overlay, and how sheathing replacement is priced. Ask both for the price itemized by structure and the difference usually explains itself.
Usually yes, and not for the reason people expect. A garage roof has no insulation and minimal ventilation because neither mattered over a car. Put a bedroom under it and you get condensation that behaves exactly like a leak. Doing it before the ceiling is lined is much cheaper than after.
Free inspection -- house, garage, addition and patio cover, not just the one. A written quote against a written scope, itemized by structure.
