Fast, Reliable Roof Repair Across Century City
Roof repair in Century City most often comes down to one thing: water finding a path through a flat or low-slope membrane, a parapet flashing, or a choked scupper. That’s the reality of a district built almost entirely as high-rise towers and luxury condos on the old Twentieth Century Fox backlot. We know these buildings because we work them nearly every week: the tower penthouses off Avenue of the Stars, the condo terraces along Century Park East, the mechanical chases that drop through occupied floors. When you call Marquis Roof Repair at (866) 705-2978, you get a crew that understands Century City roof systems from the membrane up, not a generalist who has to figure out your building on your dime.
Why Marquis Roof Repair Is Century City’s Preferred Roof Repair Company
Century City property managers and HOA boards call us because the roof surface is rarely the whole story here. The leak staining a unit on the 18th floor usually starts at a parapet cap, a terrace-door threshold, or a clogged drain on the amenity deck. Ron Thibodeau built Marquis Roof Repair around that diagnostic discipline: we investigate before we recommend. In a district where one bad flashing detail can send water through multiple occupied levels, that approach saves buildings real money and spares residents real disruption.
Our crews have worked towers along Century Park West, condominium buildings near the Westfield mall, and office rooftops across 90067. We know what the Los Angeles Department of Building and Safety expects on a commercial re-roof and what Century City’s design-review boards demand on exposed rooftop decks. That local fluency means fewer surprises and smoother inspections.
We are authorized to install products from seven major roofing manufacturers, including Roof Repair systems from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. Seven manufacturer lines, one point of contact. That breadth matters in Century City, where the right material might be a TPO membrane on one tower and a modified bitumen system on the next. We don’t push whichever brand happens to be sitting in the warehouse. We specify what the building, the climate, and the budget actually call for.

Commercial Roof Repair in Century City
Commercial Roof Repair in Century City is a specialized discipline, not a scaled-up house call. The buildings here, mostly 1960s-onward towers, carry modified bitumen, TPO, PVC, or built-up membranes over structural decks, with extensive mechanical penthouses, rooftop amenity spaces, and parapets that have to shed water while keeping it out of occupied floors below. A commercial repair might mean re-flashing a penthouse curb, re-sealing expansion joints, patching a membrane breach, or resetting a drain assembly that has pulled away from the deck. Ron Thibodeau’s crews arrive ready to match the existing system, because a mismatched patch on a Class A tower is a warranty dispute waiting to happen.
Typical commercial repair scopes across Century City run $1,800 to $7,500. Small targeted membrane patches at isolated penetrations sit near the lower end. Parapet flashing replacement with new termination bar and sealant runs higher. Full drain replacement or multiple penetration re-flashings on a large tower roof push toward the top. We provide written line-item pricing with no change orders, and we pull permits when the scope requires them.
High-Rise Parapet and Terrace Detailing
The parapet is the most common failure point we repair on Century City towers. UV and heat cycling open the sealant joints at parapet caps and counter-flashings, then winter wind drives rain back under the metal and into the building. On a condo tower along Century Park East, our crew traced a recurring leak not to the TPO membrane field but to the parapet flashing and terrace-door threshold. We reset the flashing with hot-dip hardware, re-sealed the joints, cleared the scuppers, and stopped a leak that had been staining units several floors down.
Terrace and rooftop decks add a second layer of exposure. The deck surface itself may be fine, but the transitions at door thresholds and perimeter curbs are where water gets in. We inspect those details whenever we’re on a Century City roof, even if the service call was for something else.
Drain and Scupper Clearing
A single clogged roof drain on a Century City high-rise sends ponding water through the penthouse level and into units many floors down during the first December storm. We clear scuppers, overflow drains, and primary roof drains as part of our preventive service. The membrane may have years left in it; the drain is the actual problem. We would rather clear a scupper in October than chase a leak through six floors in January.
Roof Leak Repair in Century City
Roof Leak Repair in Century City starts with patience and a good investigation, because leaks here travel. Water enters at a parapet cap on the roof, runs along a conduit, and shows up as a ceiling stain in a condo three floors down. Our Century City leak calls usually involve flat-membrane penetrations, terrace-door thresholds, or failed sealant joints, not missing shingles. We trace the water path, not just the stain, before we cut into anything.
Typical Century City leak repairs run $450 to $2,800. A simple penetration re-seal at a pipe boot or vent stack sits at the lower end. A parapet flashing repair with new metal, termination bar, and sealant runs higher. When the leak has been active through multiple winter cycles and has compromised the membrane over a wide area, the repair grows accordingly. We give honest pricing before work starts, based on what we actually find, not a guess from a photo.
Terrace Door Threshold Leaks
Terrace and balcony door thresholds on Century City condo towers are a chronic leak point. The original sealant ages out under year-round sun, and the threshold flashing, if it was ever installed correctly, lifts under thermal movement. Wind-driven rain then pushes water back under the door and into the interior flooring. We remove the old sealant, reset or replace the threshold flashing, and re-seal with marine-grade product. It is a small repair that prevents large interior damage.
Vent Boot and Pipe Penetration Repairs
Every mechanical penthouse on a Century City roof has a cluster of pipe penetrations, vent stacks, and conduit supports. The rubber or TPO boots that seal these penetrations crack from UV exposure, and the sealant around the base lets go. We replace boots, re-seal the base, and check the surrounding membrane for drying or splitting. The fix is usually quick; the damage it prevents is not.
Trusted Brands We Service in Century City
Marquis Roof Repair is authorized to install products from seven major manufacturers, including Atlas, Tamko, and Boral, so we can handle GAF repair in Century City when your building specifies it. That is a wider portfolio than most local roofers carry, and it means we can match the existing system on your Century City building instead of forcing a different brand into the repair. We keep common flashing components, sealants, and membrane accessories available for quick turnaround on 90067 jobs. The right material for your roof, not the material that is easiest for us. That is the Marquis standard, and it applies to a $450 sealant repair or a $75,000 membrane replacement.

AfterCommon Roof Repair Problems We See in Century City Homes
- Failed parapet and terrace sealant joints. Year-round UV and heat cycling open sealant at parapet caps and terrace-door thresholds, letting winter rain track back under the metal. We re-seal with marine-grade product and reset flashing with hot-dip hardware where needed.
- Clogged roof drains and scuppers. The first December storm backs up debris-clogged drains and sends ponding water through mechanical penthouses into units floors below. Preventive clearing ahead of the rainy season is the cheapest repair you can make on a Century City tower.
- Membrane punctures at mechanical penthouse penetrations. Vent stacks, conduit supports, and HVAC curbs create dozens of penetrations on a single high-rise roof. Each one is a potential entry point once the boot or sealant ages out. We inspect and repair them as a set, not one at a time.
- Corroded rooftop deck and terrace hardware. The near-coastal marine air corrodes inland-spec fasteners and non-marine finishes within a few years. Cheap hardware fails early; stainless and hot-dip hardware last decades. We specify the marine version because it costs less over ten years.
Pricing for Roof Repair in Century City, CA
Roof repair in Century City runs a real range because the buildings vary from 40-story Class A towers to smaller low-rise condo structures. Here is what we see in the 90067 market:
- Sealant joint re-sealing at parapets or terrace thresholds: $450 – $1,200 per detail
- Scupper or roof drain clearing (preventive): $300 – $900 per visit
- Vent boot or pipe penetration replacement: $350 – $850 per penetration
- Parapet flashing reset or replacement: $1,800 – $5,500 per run

What moves the price is access, not just materials. A roof that requires a crane or swing stage costs more than one with direct elevator access. A penthouse detail with a 20-story drop on one side costs more than the same detail on a two-story structure. We give free estimates with line-item pricing, so you always see the actual scope before you approve anything. Call (866) 705-2978 to schedule one.

FAQs About Roof Repair in Century City
Rooftop terrace work in Century City costs more because of access and building requirements, not material markups. Towers near Avenue of the Stars often require crane or swing-stage access, which adds thousands before a single flashing is touched. Century City design-review boards may also require specific finishes or hardware on visible deck details. The marine-grade fasteners and sealants we specify cost more than inland-spec alternatives up front, but they last two to three times longer in the coastal air. Call (866) 705-2978 for an exact quote on your building.
Check the roof drains and scuppers first. A clogged drain backs up during the season’s first heavy rain and sends ponding water through the penthouse and into units below, while the dry summer shows no sign of it. After the drains, inspect parapet flashing and terrace-door thresholds. Those are the failure points our crews find most often on Century City towers. We offer preventive drain clearing and parapet inspection ahead of the rainy season, which is significantly cheaper than chasing a leak through six floors in December. Call (866) 705-2978 to schedule a preventive inspection.
No. Ice and water shield is a steep-slope, shingle-roof product designed for winter ice dams. A low-slope membrane roof in 90067 uses the membrane itself as the waterproofing layer, bonded to the insulation or cover board underneath. There is no underlayment in the residential shingle sense. If a roofer is quoting underlayment for a flat membrane roof in Century City, that is a sign they don’t work this building type. Marquis Roof Repair knows the difference. Call (866) 705-2978 and we’ll look at your roof honestly.
Compare the scope line by line, not the total price. One Century City repair bid may include parapet flashing reset, drain clearing, and penetration re-sealing; the other may only cover the membrane patch. Look for hot-dip or stainless hardware on any exposed detail; if the bid just says “fasteners”, ask. Check whether the bidder is authorized to install the membrane brand your building already has, because a mismatched patch voids some manufacturer warranties. Marquis Roof Repair provides written line-item pricing, so the comparison is apples to apples. Call (866) 705-2978 for a bid you can actually read.
No, and you shouldn’t install one. Architectural shingles are designed for steep-slope residential roofs with gravity drainage. A Century City high-rise has a flat or low-slope membrane roof, and shingles on that deck would pond water and fail almost immediately. The roof type dictates the material. Century City buildings need modified bitumen, TPO, PVC, or built-up membranes, installed by a commercial crew that understands high-rise detailing. Marquis Roof Repair works all of those systems. Call (866) 705-2978 if you need an honest assessment of what your building’s roof type actually requires.
