How we think about this work in Los Angeles.
Exterior work is moisture management, full stop. Roofing, siding, stucco, decks, and concrete all exist to move water away from the building before it has time to soak in. We detail every transition — roof-to-wall, wall-to-deck, deck-to-door — as if it will see a hose test, because in winter it will.
California climates are deceptively hard on exteriors. UV is brutal. Marine air corrodes fasteners. Wildfire embers land on debris in valleys. We default to WUI-compliant materials (Class A roofing, ⅛" mesh vents, ignition-resistant siding) on every exterior job, even where it's not yet required — it's $2–6K extra and it's the difference between a saved house and a lost one.
The schedule, written out.
Every project varies, but the cadence below holds for most roofing jobs in Los Angeles. We publish it on purpose — the schedule is the contract.
Week 0
Inspection + scope
Roof + flashing inspection, moisture probe of siding, deck post + ledger check, photo documentation.
Week 1–2
Permits + material procurement
Permit (most cities require for re-roofs, additions, decks > 30" off grade); material delivery scheduled around rain forecast.
Week 2–4
Tear-off + dry-in
Selective demo, sheathing inspection, replace rotted decking, install underlayment + flashing.
Week 4–6
Install
Roof, siding, stucco scratch + brown + finish, deck framing + decking, concrete forms + pour.
Week 6–7
Trim + paint + seal
Trim, paint, sealant on penetrations, deck stain or color.
Week 7–8
Inspection + warranty
Final inspection, manufacturer warranty registration, owner walk.
Materials & assemblies.
These are the defaults we write into the contract before you change a thing. They're the floor, not the ceiling — every spec can be upgraded; none should be downgraded without a serious reason.
| Component | Default spec | Why |
|---|---|---|
| Roofing | 30-yr architectural shingle, standing-seam metal, or single-ply TPO/PVC for low-slope | Standing-seam metal wins lifetime cost in most CA climates. |
| Underlayment | Synthetic underlayment + peel-and-stick ice-and-water at valleys and penetrations | 30-lb felt is no longer the right baseline. |
| Siding | Fiber cement (Hardie), engineered wood (LP SmartSide), or stucco with weep screed and 2-layer WRB | WRB layering is what controls 90% of stucco failures. |
| Deck framing | PT lumber for posts, joists, ledger; stainless or coated fasteners; flashing at ledger | Galvanized fasteners on PT lumber corrode in 5 years. |
| Decking | Composite (Trex, TimberTech), thermally modified hardwood, or kiln-dried IPE with hidden fasteners | Composite is the lowest-maintenance default for CA sun. |
| Concrete | 4000 psi mix, #4 rebar @ 16" o.c., proper expansion + control joints | Cracks come from poor jointing, not from the mix. |
Hidden costs we flag up front.
A Los Angeles project budget that ignores the items below is a budget that will go over. We surface them in the first walk-through — not after a wall is open.
| Line item | Range | When it hits |
|---|---|---|
| Sheathing replacement | $8–$22/sqft | tear-off reveals rot or delaminated OSB |
| Deck ledger flashing repair | $1.5K–$6K | ledger was nailed, not bolted with flashing |
| Stucco crack repair (full re-skim) | $6K–$18K | 1980s synthetic stucco has reached end of life |
| Tree removal / overhead clearance | $1.5K–$8K | roof or wall access requires it |
| Permit (re-roof + structural) | $300–$2.5K | many cities now require for re-roof + decks |
Why building in Los Angeles is its own thing.
Climate & building stock
Greater Los Angeles is a warm-summer Mediterranean climate (Köppen Csa) with long dry summers, Santa Ana wind events, brushfire exposure on the WUI, and an annual rainfall window concentrated between November and March. Building stock skews to single-story stucco bungalows, post-war ranches, and 1960s–80s wood-frame on raised perimeter or slab — many of which were built before today's Title 24 envelope and ventilation rules.
Seismic & soils
LA sits on the Newport-Inglewood, Santa Monica, Hollywood, and Sierra Madre fault systems. Soft-story apartments and pre-1980 cripple-wall single-family homes are the two biggest seismic liabilities; the Soft-Story Mandatory Retrofit Program (Ordinance 183893) is the framework most multifamily clients deal with, and FEMA P-50 / Brace+Bolt is the standard for single-family.
Code & amendments
City of LA uses the 2023 California Building Code / CRC / CMC / CPC / CEC + 2022 Title 24 Part 6, layered with LA-specific amendments and the LA Green Building Code. ADU rules follow LAMC §12.22 A.33 plus statewide AB 671 / SB 9 / SB 1211 updates current for 2026.

Los Angeles — inspection cadence
From permit to occupancy.
- 1.Pre-construction: permit issued, NOC posted, dust + erosion control set
- 2.Underground: plumbing + electrical + grounding before slab pour
- 3.Foundation: rebar + hold-downs + anchor bolts before concrete
- 4.Framing: rough framing + shear nailing + strap inspection (often combined)
- 5.Rough MEP: rough electrical, plumbing top-out, mechanical, T-24 envelope verification
- 6.Insulation + drywall: HERS verification of duct leakage + envelope tightness
- 7.Final: building, electrical, plumbing, mechanical, planning — same-day clustering preferred
Los Angeles — how locals fund this
Financing instruments.
- HELOC against primary residence — most common ADU funding (60–80% CLTV)
- Cash-out refinance — preferred when current first mortgage rate is above market
- Renovation construction loan (one-time-close 7/1 ARM)
- RenoFi / ADU-specific second loans — based on after-completion appraisal
- Property-tax-assessed PACE financing for HVAC, panel, envelope upgrades
cheaper alternatives & their tradeoffs
What we'd consider — and what we wouldn't.
Overlay re-roof (shingle over shingle)
30% cheaper but voids most warranties + traps moisture; never on a building you plan to keep.
EIFS over stucco
Better thermal but historically a moisture-management nightmare — only with rainscreen detail.
Pressure-treated decking
60% cheaper than composite but requires re-staining every 2 years to last.
pitfalls — what we fix on takeover jobs
Mistakes to avoid.
- Skipping the moisture probe of stucco before scope-of-work — a 'paint job' turns into a $25K re-skim
- Mounting a deck ledger to siding without flashing — #1 source of catastrophic deck failure in CA
- Not detailing kick-out flashing at roof-to-wall — drives water behind the siding for years
- Installing concrete without proper joint spacing — random cracking that no patch will hide
- Skipping a soils report on hillside lots — Hillside Ordinance triggers caissons and import fill that double foundation cost
- Under-sized service panels — most pre-1990 homes are 100A, not enough for ADU + heat pump + EV
- Mis-reading R1 vs R1V1 zoning — height + FAR rules vary by hillside designation
- Ignoring the LADWP separate-meter rule when renting the ADU long-term
- Building over a sewer easement — requires LASAN encroachment letter before plan check

When to do it yourself — and when not to.
| Situation | DIY-defensible | Call a licensed GC |
|---|---|---|
| Single-layer tear-off, no fire-zone overlay | Permit is owner-builder-eligible if you can document Title 24 compliance. | Cool-roof reflectance + manufacturer warranty math typically pays for the GC. |
| Parcel inside a Very High FHSZ (Bel Air, Topanga, Mandeville) | Stop. Class A + 7A vent and underlayment compliance is a hard inspection gate. | Always — we document each Chapter 7A component on the permit card. |
| Hillside Ordinance lot needing skylight + new vent stacks | Not realistic; BHO triggers extra plan-check rounds. | We bundle BHO + Title 24 + 7A in one submittal to skip multi-round review. |
| Flat roof recoat (e.g. Spanish-style parapet roof) | Defensible for small areas under 200 sqft. | Warranty + reflectance verification is usually worth the upgrade to a certified installer. |

In short.
- How long does an LA composition reroof take?
- 3–5 days on a 2,000 sqft house.
- Composition vs tile — what lasts longer in LA?
- Tile 40–50 years vs composition 25–30. Tile costs 2x but lasts a lifetime.
