A roof tear-off in Rosemead removes every layer of old roofing, felt and flashing until only the wood deck remains. It is the first stage of most roof replacement projects we take on, and it is the only way to see the condition of the sheathing before a new roof seals it in for decades.
Houses built in the 1950s often hide more than one roof. We regularly strip two layers of composition shingle, and sometimes a layer of old wood shake underneath, before reaching the original skip sheathing or plank deck.
What a roof tear-off in Rosemead involves
Removal is heavy, loud work, and it is where most of the surprises in a reroof show up. A complete tear-off covers:
- Shingles, tile or shake, plus every layer beneath them.
- Old felt underlayment, cap sheet and any tar patches.
- Rusted drip edge, valley metal, step flashing and pipe jacks.
- Every old nail pulled or driven flush so the new underlayment lies flat.
- Loading debris straight into a dumpster or trailer, then hauling it away.
We tear off and dry in one section at a time when weather is uncertain, so the house is never left open to a passing shower. Each evening any exposed deck is covered with underlayment or tarps.
Removing multiple layers of old shingles
Each extra layer adds labor, disposal weight and dumpster space. It also hides the deck from view, which is why a second or third layer is the most common reason we quote a tear-off instead of an overlay.
| Layer found | What it means for the job |
|---|---|
| Single shingle layer over plywood | Fastest removal; deck often only needs spot repair |
| Two shingle layers | Roughly double the debris; long nails may have split older boards |
| Shingles over wood shake | Shake must come off; deck is usually skip sheathing that needs solid plywood over it |
| Tar and gravel or rolled roofing over a low-slope addition | Separate removal method and its own replacement system |
Skip sheathing, the spaced boards used under original shake roofs, cannot support shingles. When we find it, the quote already includes a line for solid sheathing so the decision is not made in a rush on tear-off day.
What happens when the deck under the old roof is rotten?
Wood around chimneys, valleys, pipe boots and eaves rots first, because that is where old leaks ran. Once the roof is off we walk every sheet and probe any dark or soft areas.
- We mark and photograph each damaged sheet or board.
- We show you the photos before replacing anything beyond the allowance written into your quote.
- Rotted wood is cut back to sound framing and replaced with plywood or OSB of matching thickness.
- Damaged rafter tails or fascia found at the eave are priced separately and repaired before the drip edge goes on.
When rot reaches the framing itself, rafter sistering and structural fixes fall under roof deck and dry rot repair.
Signs of deck trouble you can spot before tear-off
- Dips between rafters, visible when you sight along the roofline from the street.
- Spots that feel soft or bouncy when a roofer walks them.
- Dark stains or pinholes of daylight on the underside of the boards, seen from the attic.
- Rusted nail tips in the attic ringed with old water marks.
- Shingles that will not lie flat because the wood under them has cupped.
Any one of these lets us raise the deck allowance in the quote before work starts, instead of surprising you on tear-off day.
Tear-off day by day: dumpster, crew and haul-away
On a typical single-story shingle home in the San Gabriel Valley, the schedule runs like this.
- Before day one: the permit is issued, the dumpster is placed where it will not crack your driveway, and materials are ordered.
- Day one: tarps go over plants and walls, the crew strips the roof and replaces damaged sheathing.
- Day one or two: drip edge and underlayment go down so the house is dry overnight.
- Following days: flashing, roof covering and ridge are installed, then the inspector visits.
- Last day: dumpster removed, yard swept with a magnet, gutters cleared of grit.
Most tear-off and reroof jobs on a single-story home take 2 to 4 working days. Two-story homes, tile roofs and several layers stretch that. Next comes new roof installation or, on tile homes, a tile underlayment replacement where the original tile goes back on.
Rosemead's Building and Safety Division issues the reroof permit before the dumpster arrives, and LA County Public Works Building & Safety does the same for unincorporated pockets. A tear-off is permitted work, so California requires a CSLB-licensed contractor in the C-39 roofing class, and CSLB has required C-39 roofers to carry workers' compensation from 2017 on, even with no employees. Check both at cslb.ca.gov before the first shingle comes off.

How do we keep nails and debris out of the yard?
- Tarps or plywood screens over flower beds, AC condensers, pool edges and windows below the eaves.
- Debris chutes or direct dumping into the bin, rather than throwing roofing onto the lawn.
- Gutters cleared at the end of the job, since loose granules collect there.
- A rolling magnet sweep of the lawn, driveway and street edge every evening and again at the end.
What sets the cost of a tear-off?
Manta's 2025 calculator, useful only as a planning figure, runs from $5,582 to $7,555 for an LA County asphalt shingle job with removal included, not counting permits and fees. Disposal is a real share of that number: shingles are heavy, and dump charges rise with every extra layer. Real quotes vary with the items below.
- Number and type of layers coming off.
- Roof size, pitch and number of stories.
- Dumpster access, especially on narrow lots or homes with a long rear driveway.
- Sheathing replacement once the deck is exposed.
- Tile handling, which takes more care and labor than shingles.
Tear-off is also where bids differ most in what they leave out. Check that each one states the number of layers it assumes, the dumpster size and trips, and the per-sheet deck price. A bid that assumes one layer on a house carrying two will grow once removal starts.
Payment options are worth raising as we go through the numbers.

Where we handle roof tear-off
- Rosemead
Post-war homes where two composition layers, and sometimes old shake, sit over plank or skip sheathing that has to be exposed.
- Alhambra
Older homes with long rear driveways and detached garages, where dumpster placement and debris runs need planning.
- Montebello
Hillside streets where steep driveways limit dumpster placement, so trailers and smaller loads keep removal moving.
- Monterey Park
Sloped lots where tarps and plywood screens protect retaining walls, plants and pools below the eaves during removal.
- El Monte
Tract homes with low-slope rear additions, where tar-and-gravel or rolled roofing comes off by a different method than the shingles.
- San Gabriel
Older homes where shingles were laid over original wood shake, so removal reaches skip sheathing that needs solid plywood.
- Temple City
Closely spaced houses on narrow lots, where debris chutes and side-yard protection matter more than open-yard dumping.
- Pico Rivera
Post-war tracts near the Rio Hondo where decking under repeated reroofs often shows rot at the eaves and valleys.
- Whittier
Older homes on hillside streets where shingle layers sit over board decking and dumpster access shapes the schedule.

Roof Tear-Off questions
How many days does a full tear-off take?
Removal itself usually takes a single day on a one-story shingle house. The full tear-off and reroof typically runs 2 to 4 working days, depending on layers, pitch and how much sheathing needs replacing. Tile and two-story homes take longer. We give you a day-by-day outline with the quote.
What happens if rotted decking is found under the old roof?
Work pauses, and you see photos of the damaged wood before anything beyond the quote's allowance is replaced. Each sheet is priced in writing ahead of time, so there is no guesswork. Rotted wood is cut out to sound framing and replaced with new plywood or OSB before underlayment goes down.
How do you keep nails and debris out of the yard?
We cover plants, AC units and pool edges with tarps, drop debris straight into the bin, and run a rolling magnet over the lawn, driveway and curb every evening. A final sweep and gutter clean-out happen on the last day, and reviewers often mention clean job sites.
Will the tear-off damage my driveway or lawn?
A loaded dumpster is heavy, so we place it on boards to spread the weight and avoid soft lawn or thin concrete edges. If access is tight, we use a smaller trailer and make more trips. We discuss placement with you before delivery.
Can we stay in the house during a tear-off?
Yes. Expect loud scraping and hammering for most of the first day, and some dust in the attic. Move fragile items off shelves on walls that share the roofline, keep pets inside, and park on the street. The roof is closed and dry at the end of each workday.
Is a permit required for a roof tear-off?
Yes. A tear-off is part of a reroof, and reroofs need a building permit in Rosemead and surrounding cities. We pull it, price it on a line of its own, and book the inspection once the new roof is on. If your address is in an unincorporated pocket, your permit is issued by the Building & Safety team at LA County Public Works rather than a city.
