Shingle Roof Replacement in South El Monte from $7. Composition on a century of different decks. Free inspection and a written quote.
On the residential streets this is ordinary post-war shingle work. What is worth checking here more than elsewhere is the layer count, because a fair number of these roofs have been overlaid once already -- and a second overlay is not on the table, which turns a cheap quote into a tear-off.
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. Start with which city, because it changes the permit and it changes the building type. South El Monte carries a large share of light industrial, and a large-area low-slope roof with plant on it is priced by the square foot and by the number of details -- nothing like a house.
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.
The single most useful fact about working here is that this is a DIFFERENT CITY with its own building department. A contractor who files an El Monte permit for a South El Monte address loses you a week, and it happens constantly because the names are so close. The industrial share also means large-area low slope with plant on it, which prices nothing like a house.
South El Monte is a separate incorporated city with its own building department -- the most commonly muddled fact about permitting roofing work in this area.
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.
First, the permit: this is a separate incorporated city with its own building department, and filing an El Monte application for a South El Monte address costs a week.
The state law is the same but the department is not, so the conversion permit and any roofing work with it go through South El Monte rather than El Monte.
Tile is a minority covering on the residential side and essentially absent on the industrial side, so a South El Monte tile job is usually a one-off rather than a tract standard.
This is where the genuinely commercial low slope is.
On a light-industrial roof, partial usually means working in sections around plant that cannot be shut down.
Oldest settlement in the valley. Rarely one roof.
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.
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.
You can, and on a parcel with several structures it is often the right answer, because each structure has its own 50% test. What nobody volunteers is that the fixed costs -- permit, mobilization, waste, a crew day -- do not shrink. Phasing one house roof over two years usually costs more than doing it once.
Re-roofing is permitted work and we pull it. Which city matters more here than almost anywhere: El Monte and South El Monte are separate incorporated cities with separate building departments, and an application on the wrong desk costs a week. The inspection that comes with the permit is your independent check that the specification you paid for is what went on.
Free inspection -- house, garage, addition and patio cover, not just the one. A written quote against a written scope, itemized by structure.
