Roof Replacement in Century City, CA: What It Costs and What to Expect
Roof replacement in Century City typically runs $9 – $16 per square foot for flat membrane work on commercial and luxury condo buildings, with most mid-rise projects landing between $40,000 and $180,000 depending on decking condition, parapet detailing, and design-review mandates. That’s the honest number: the flat, low-slope roofs that dominate Century City are not shingle jobs, and pricing reflects the class of building, the equipment access constraints, and the membrane system specified. At Marquis Roof Repair, we plan for the real jobs Century City throws at us, and we price the upgrades in writing before the first square comes off.

Fast, Reliable Roof Replacement Across Century City
Century City is not a typical Los Angeles roofing market. It’s a dense cluster of high-rise office towers, luxury condo towers, and rooftop amenity decks packed into a few square blocks east of Beverly Hills, and almost every roof here is a flat, low-slope system built over a concrete deck. That changes how a roofer works: hoisting membranes up service elevators, coordinating with building management around tenant schedules, and navigating design-review rules that don’t apply to houses in Culver City or West Hollywood. Our team knows the buildings along Century Park East, Century Park West, and Avenue of the Stars. We know the property managers, we know the loading dock protocols, and we know which buildings require plan approval before a warranty is even discussed. When you call Marquis Roof Repair at (866) 705-2978, you reach a crew that has actually opened roofs in Century City, not a contractor reading the address for the first time.

Why Marquis Roof Repair Is Century City’s Preferred Roof Replacement Company
Most roofing companies in Los Angeles sell one brand. That’s fine until the wrong membrane gets recommended because it’s the only one on the truck. Marquis carries an authorized line from seven manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That breadth matters in Century City, where a building’s design-review board may specify a particular membrane color, thickness, or fire rating. We match the material to the building, not the building to the material.
Century City building owners and HOA boards call us because we do the full roof lifecycle: diagnostic inspection, targeted repair, and full Roof Replacement under one name. We investigate before we recommend. On more than a few Century City buildings, what started as a leak call ended with a written report that saved the owner from an unnecessary tear-off. Ron Thibodeau, our founder, set that standard from day one: diagnose honestly first, replace only when the roof actually needs it. It’s a repair-first philosophy that has earned Marquis a strong reputation from Avenue of the Stars to the towers fronting Century Park West.
Flat Roof Replacement in Century City
Flat Roof Replacement is the bread-and-butter of Century City roofing. Nearly every building in the 90067 zip code runs a modified bitumen, TPO, PVC, or built-up membrane over a concrete or gypsum deck, and the job means removing the old system, correcting deck defects, and rebuilding flashing at parapets, curbs, and drains. On a small condo tower in Century City, a flat roof replacement typically runs $12 – $16 per square foot installed. On a larger Class A office building with heavy mechanical screens and extensive terrace detailing, a full project can comfortably exceed $150,000. The governing factor is rarely the membrane itself; it’s the deck condition underneath and the design-review requirements above.
Membrane Systems for High-Rise Decks
Century City buildings demand membranes that handle ponding water between rain events and intense UV during the long dry season. TPO and PVC dominate for their weld-seam reliability and reflectivity; modified bitumen remains common on older towers with heavy foot traffic. We recommend based on the building’s specific deck composition and drainage capacity, never on what’s in stock that week.
Parapet and Drain Rebuilding
On a Century City flat roof, the membrane is only half the system. Parapet flashing, scupper liners, and drain bowls take the real abuse. When we replace a roof on Century Park East, we rebuild the parapet detailing to original-height or design-review-approved specs, not just a slap-over. That’s what prevents the December storm from sending water down through the mechanical penthouse into units ten floors below.
Roof Installation in Century City
Roof Installation in Century City covers both full replacement tear-offs and new construction on podium decks and mechanical penthouses. New construction work here is typically attached to renovations of 1960s-era towers, where a rooftop amenity deck or a re-roofed mechanical housing is part of a larger capital project. A full new installation on a Century City podium deck runs $14 – $18 per square foot, driven by the need for tapered insulation, drainage re-sloping, and heavy-gauge walkway pads. These are engineering-heavy jobs, and we coordinate with the structural engineer, the waterproofing consultant, and the building’s design-review committee from the first submittal.
New Construction and Podium Decks
High-rise podium decks over occupied space need a roof assembly that functions like a waterproofing system, not a residential shingle roof. We install layered assemblies with reinforced membrane, protection board, and drainage matting. The goal is a dry slab the day we leave, with a warranty the building board accepts.
Mechanical Penthouse Re-roofing
Century City towers hide HVAC units, cooling towers, and elevator machinery under rooftop penthouses that get re-roofed far less often than they should. When we open one, we document the curbs, the pipe penetrations, and the deck condition in full before pricing the replacement. That documentation is what property managers and HOA boards use to approve the scope, and it keeps the job moving without mid-project arguments.
Trusted Brands We Service in Century City
Marquis is authorized to install materials from seven major manufacturers, including GAF, CertainTeed, and Owens Corning. For Century City customers, that means the right membrane spec is always available, not the one a single-brand roofer pushes because it’s all they carry. We keep local supply relationships for TPO, PVC, and modified bitumen systems across the 90067 area, which shortens lead times when a building’s design-review board approves a replacement and the clock starts. Whether your board requires a specific CertainTeed PVC for its reflectivity or a Boral tile for a terrace accent, one point of contact handles the whole scope. From first inspection to final shingle, we’re built to the Marquis standard.

AfterCommon Roof Replacement Problems We See in Century City Homes
- Design-review scope changes after the contract is signed. Century City’s strict design-review and view-corridor standards can mandate low-profile mechanical screens or altered parapet heights once plans are submitted. These changes turn a like-for-like membrane swap into a permit-driven scope negotiation, and they’re the single biggest reason a Century City roof quote moves.
- Failed parapet and terrace flashing during the first winter rain. Wind-driven water at parapet walls and terrace door thresholds is a classic Century City failure. Water enters at the flashing, travels through the mechanical penthouse, and shows up as a ceiling stain in a luxury condo unit many floors down.
- Ponding on low-slope membranes from undersized drains and clogged scuppers. Many 1960s-era towers in Century City have drain systems that were marginal when new and are now partially blocked. Ponding only shows up after the first December storm, and by then the membrane has been sitting in water for weeks.
- Dry, split decking hidden under an old built-up membrane. On Avenue of the Stars, we opened a 1960s office-tower roof to find the original built-up membrane bonded to a dry, split deck and corroded flashing at every penetration. Our tech documented the framing and wiring in the mechanical penthouse, wrote a TPO replacement with a $12k code-upgrade allowance for new drip edge and ice and water shield, and priced the surprise curb rebuild in writing before tearing off the first square. That’s the Century City reality.
Pricing for Roof Replacement in Century City, CA
Expect to pay $9 – $16 per square foot for a commercial flat roof replacement in Century City, with smaller condo tower jobs starting around $40,000 and larger office building work exceeding $150,000. What moves the number: deck condition once the old membrane is stripped, design-review conditions that force parapet-height or screening changes, and whether the building’s drains and scuppers need enlargement to eliminate ponding. We price each scope with a written allowance for code upgrades and we put any surprise in writing before we touch it. Estimates are free, and they’re line-item specific. Call (866) 705-2978 for your Century City quote.

FAQs About Roof Replacement in Century City
Yes, in nearly every Century City building, even a like-for-like membrane replacement must clear a design review before the city issues a permit. That review can require low-profile mechanical screens, altered parapet heights, or specific membrane colors, and those conditions change the scope and cost of the job. Marquis handles the submittal and prices the changes in writing before work starts. Call (866) 705-2978 to talk through your building’s review requirements.
The most common surprises are dry, split decking hidden under an old built-up membrane, corroded flashing at penetrations, and rotted curb structures inside mechanical penthouses. We document every one of these in a written report and price the repairs as a specific line item, not a vague “additional work” clause. That’s how we protect Century City owners from mid-project cost shocks.
We inspect the drain bowls, scuppers, and slope before we quote, and when ponding is evident we write drain enlargement or taper-system correction into the replacement scope. Clearing a clogged drain is a repair; fixing the drainage profile so water never ponds is a replacement decision. In Century City, where a single failed drain sends water through a mechanical penthouse into units below, we treat drainage as part of the roof, not an afterthought.
No, architectural shingle work is rare in Century City. The building stock is almost entirely high-rise commercial and luxury condo towers with flat, membrane-roofed decks. While Marquis installs asphalt and architectural shingles throughout Greater Los Angeles, the realistic scope in the 90067 zip code is flat roof replacement and roof installation on podium and mechanical-penthouse decks.
A “square” is a roofing unit equal to 100 square feet. When we price a Century City flat roof at $12 per square foot, that’s $1,200 per square. Most condominium towers in Century City run anywhere from 40 to 200 squares depending on building footprint, so the per-square number directly scales your total project cost. We break down your quote by square and by line item, so you can verify the math before you sign. Call (866) 705-2978 for an exact quote on your building’s footprint.
