Fast, Reliable Roof Replacement Across Lennox
Roof replacement in Lennox is not a job you figure out by calling the cheapest bidder. This is a 1.5-square-mile pocket of tightly packed 1940s and 1960s apartment rows, duplexes, and triplexes where marine-layer moisture settles on flat and low-slope roofs every night, and where a rusted fastener on one building shows up as a ceiling stain in the unit next door. At Chatham Roof Repair, we have torn off and replaced enough Lennox roofs to know which materials fail early here and which ones hold. If you own or manage a building in the 90304 zip code and your roof is showing age, call us at (866) 361-1724 for a straight assessment and a written estimate.
We work across Lennox every week, from the dense apartment blocks off Hawthorne Boulevard and Lennox Boulevard to the duplex rows near 104th Street and the smaller residential streets that dead-end at the neighboring city lines. Our roofing crew knows the parking constraints, the shared parapet walls, and the tenant access schedules that make roofing work here different from a single-family job in El Segundo or Del Aire. If your roof needs to be inspected, repaired, or fully replaced, we will tell you which one it actually needs. Call (866) 361-1724 and we will come look.

Why Chatham Roof Repair Is Lennox’s Preferred Roof Replacement Company
Roofing in Lennox is a specialty, not a sideline. We are a Roof Replacement company that handles inspection, repair, and full replacement under one roof. That matters here because most Lennox buildings are rentals with absentee owners. When a property manager calls us about a leak, the actual problem is often three buildings down the row, not at the address where the stain appeared. We find the failure at its source because we understand the shared-wall construction that defines this city.
Lennox homeowners and property managers call us because we carry materials from seven major manufacturers, including CertainTeed, Tamko, and Boral. That multi-brand inventory means we can match an existing roofline instead of forcing a product that looks wrong and performs worse. The company is owned and led by Nelson Quarry, who oversees every estimate and every scope of work. When you call (866) 361-1724, you get a roofer who has walked these blocks, not a generalist with a roofing division.
Response time to Lennox is measured in days, not weeks. We schedule our South Bay crews around the city because we know the work here is steady. A roof that fails in Lennox fails fast. The marine layer does not wait for an appointment.
Styles & brands we work with






Asphalt Shingle Roof Replacement in Lennox
Asphalt Shingle Roof Replacement in Lennox is most common on the few detached single-family homes and the older duplex rows that still carry original asphalt shingles from the 1950s and 1960s. These shingles have spent decades baking under a South Bay sun that cracks their surface, then soaking in nightly marine-layer moisture that works into every crack. By the time we see them, they are usually curling, losing granules, or letting water through at the valleys and nail lines. A full asphalt shingle replacement on a Lennox single-family roof typically runs $8,000 to $14,000 depending on roof size, decking condition, and tear-off requirements. On a duplex or triplex with shared roof areas, the job runs $14,000 to $26,000 because the work spans multiple units and often requires coordination with tenants and the neighboring property owner.
Architectural Shingle Choices
Architectural shingles are the right upgrade for Lennox owners who want a thicker, longer-wearing replacement that holds up to UV and thermal cycling better than three-tab. They carry stronger wind ratings and most manufacturers back them with extended warranty language that matters when you are protecting a rental property. We quote architectural shingles from GAF, CertainTeed, and Tamko so you can compare the warranties and the look side by side.
Decking and Underlayment Repair
Lennox roofs rarely fail at the shingle alone. The decking underneath takes on moisture through rusted fasteners and failed flashing, especially at the parapet ties and low-slope drain points. We inspect and replace softened or rotted decking as part of every asphalt shingle job, and we specify hot-dip galvanized fasteners in place of the standard steel that corrodes fast in this coastal air. Skipping that step is how a new roof in Lennox becomes a leaking roof within five years.
New Roof Installation in Lennox
New Roof Installation in Lennox is not a standard residential job and should not be priced like one. Most new roofs here go onto low-rise apartment buildings, duplexes, and triplexes with flat or low-slope membranes, built-up roofing, or modified bitumen. A full new membrane roof on a typical Lennox duplex or triplex runs $18,000 to $38,000 depending on roof square footage, parapet work, drainage, and whether the old system has soaked the insulation or decking. A new flat roof on a larger apartment building can run $40,000 to $90,000 or more. These are not single-family shingle numbers, and any bid that looks like one should be questioned hard.
Flat and Low-Slope Systems
Lennox flat roofs fail at the seams, the drains, and the parapets. The marine layer puts moisture on the surface every night, and any seam that has cracked from thermal cycling lets that water into the substrate. We install and replace modified bitumen and built-up membranes with sealed lap joints and proper slope to drain, and we pay particular attention to the points where one building ties into the next. A new membrane here is only as good as the flashing above it.
New Construction and Addition Roofs
Where Lennox owners are adding a unit or rebuilding after a fire or teardown, we handle roof installation for the new structure. The work starts with a dry-in inspection, then proceeds to the roof system specified for the project. We pull the necessary permits and make sure the finished roof meets the current code requirements for the 90304 area. New construction roofing here needs to be planned around the same shared-wall and drainage constraints as a replacement roof.
Trusted Brands We Service in Lennox
We install roofs using products from seven major manufacturers, and for Lennox customers that includes GAF, CertainTeed, Tamko, and Boral among others. Why does the brand matter here? Because a Lennox roof lives a hard life. UV on the flat surfaces, moisture in every seam, thermal expansion every afternoon. Some membranes and shingle lines handle those conditions better than others, and some manufacturers offer stronger warranty language for commercial and multi-unit buildings. We keep our local inventory stocked for the roof types we see most in Lennox, which means faster material turnaround when your building cannot wait. Seven major brands. You choose the product that fits your roof, your budget, and your warranty goals.
Common Roof Replacement Problems We See in Lennox Homes
- Rusted fasteners and drip edge at parapet ties. The marine-layer moisture that settles on Lennox roofs every night attacks standard steel fasteners within a few seasons. When those fasteners fail at the point where one building ties into the next, the leak goes straight into the neighboring unit’s ceiling.
- UV-cracked membranes and asphalt shingles. Lennox gets long, hot, dry stretches that bake roofing surfaces. Thermal cycling cracks the membrane and splits the shingles. Once the cracks open, the next winter rain goes right through.
- Ponding water at low-slope drain points. Flat roofs on 1940s and 1960s apartment rows were often built with marginal slope. When drains clog or settle, water ponds. A ponded seam on one roof becomes a stain on the ceiling next door, and the owner of the stained unit chases the wrong building.
- Shared-wall and parapet flashing failures. Adjoining buildings share walls and parapets. When the flashing between them corrodes or pulls loose, the leak is nobody’s responsibility and everybody’s problem. We find the actual failure and fix it at the tie, not at the stain.

AfterPricing for Roof Replacement in Lennox, CA
Roof replacement in Lennox runs on a different price curve than the owner-occupied single-family neighborhoods around it. An asphalt shingle replacement on a small Lennox house starts around $8,000. A modest duplex roof starts around $14,000. A full flat-roof tear-off and membrane replacement on an apartment building most often lands between $30,000 and $90,000 depending on square footage, parapet length, drainage work, and decking condition. The biggest variable on a Lennox flat roof is what we find under the membrane. Rusted fasteners and water-rotted decking add material and labor fast, and skipping them guarantees the new roof fails early. We give written line-item estimates and free inspections. Call (866) 361-1724 to get an exact number for your building.
Coastal-Spec vs. Inland-Spec: The Price Gap That Decides Lennox Roofs
Here is the information-gain detail most roofers won’t volunteer. In Lennox, the materials that decide how long your new roof lasts are not the shingles or the membrane. They are the fasteners, the drip edge, the flashing, and the underlayment. The marine layer that rolls in off the coast every night settles on thousands of flat and low-slope apartment roofs packed into this tight 1.5-square-mile pocket. Standard steel fasteners start to rust within a few seasons. Cheap galvanized drip edge corrodes at the parapet tie. Flashing that was never meant for a salt-moisture environment pulls loose and opens the seam to the building next door. A coastal-spec roof replacement specifies hot-dip galvanized or stainless fasteners, marine-grade flashing, sealed parapet ties, and underlayment with ice and water shield run through the valleys and penetrations. That coastal spec typically adds 8% to 14% to the material and labor line on a Lennox flat-roof building. On a $40,000 apartment roof, that is roughly $3,200 to $5,600 more up front. The inland-spec version, the one built with standard steel and basic flashing, saves that money now and costs two or three times as much within a decade when the roof fails at the parapet and the neighboring unit’s ceiling opens up. In Lennox, the cheap spec is the expensive spec. We have seen it too many times to recommend it to anyone.
On a narrow block off 104th Street, our crew tore off the aging modified-bitumen membrane on a 1940s duplex row and found the steel fasteners and drip edge had rusted through where coastal moisture collected at the parapet. We replaced the decking where it had softened, laid new underlayment with ice and water shield through the valleys and penetrations, set hot-dip galvanized fasteners, and finished with sealed parapet flashing so the tie to the neighboring building stopped leaking into the unit next door. That job cost more than the inland-spec quote the owner originally got. It also stopped the leak the owner next door had been living with for two years.

FAQs About Roof Replacement in Lennox
The coastal-spec roof costs more because it replaces standard steel fasteners, drip edge, and flashing with hot-dip galvanized or stainless hardware that will not rust out in the nightly marine layer. The price difference is 8% to 14% on most Lennox flat-roof buildings. The inland version saves that now and fails at the parapet tie within a decade. Call (866) 361-1724 and we will show you the line-item difference on your building.
The owner of the building where the failure originates is responsible for the repair, and that is often not the building where the stain appears. In Lennox’s shared-wall duplex and apartment rows, a puncture or ponding seam on one roof surfaces in the neighboring unit first. We trace the leak to its actual source before anyone spends money. Call (866) 361-1724 and we will inspect the common flashing.
Put the two bids side by side and compare four lines: fastener spec, flashing material, underlayment through valleys and penetrations, and decking replacement scope. If one bid does not name the fastener and flashing spec, it is the inland-spec bid, and it will cost more over time. We write our Lennox estimates so every line is visible. Call (866) 361-1724 for a line-item quote you can actually compare.
Most Lennox apartment buildings from the 1940s through the 1960s have flat or low-slope roofs and need a modified-bitumen or built-up membrane system, not shingles. Architectural shingles apply to the detached homes and the few duplex rows with pitched roofs. We install both, and we match the system to the building, not to a product we happen to prefer. Call (866) 361-1724 to find out which one your building needs.
Yes. We coordinate roof tear-offs and membrane replacement around tenant schedules, which in Lennox means property-management timelines, quiet-hours limits, and access windows for the units below the roof. We do the loud work in scheduled blocks and keep tenants informed. If your building is occupied, we handle the scheduling. Call (866) 361-1724 and we will map out the timeline.
