If you’re a landlord or homeowner staring at water stains after the first winter rain, call (855) 597-2817 for a free estimate. We’ll tell you what’s wrong, what it costs to fix, and which materials actually make sense for your roof.
Why Seacrest Roofing Is Lennox’s Preferred Roof Replacement Company
Lennox isn’t an incorporated city, and that changes everything about how a roof replacement gets permitted and inspected. We’ve pulled enough LA County permits here to know which details trigger a correction notice: scupper sizing on flat roofs, flashing details at shared property lines, and the wind-rated nailing pattern the inspector checks before signing off. That’s the work we do every week, and it’s why local landlords and homeowners keep our number.
Our Roof Replacement team is led by Noel Chambers, who has spent years working on the exact housing Lennox has: 1940s and 60s stucco boxes, small apartment buildings, low-slope roofs packed tight against the neighbors. We carry seven shingle brands so we never have to force a single product line onto a roof that needs something different. When you call us for an estimate, you get options, not a pitch.

Roof Replacement Contractor in Lennox
Seacrest Roofing is the roof replacement contractor Lennox property owners call when a roof has reached the end of its service life and patching no longer makes sense. The job starts with a full inspection of the existing roof deck, underlayment, flashing, and drainage, then we map out whether a full tear-off is needed (it usually is on Lennox’s older stock) and what the replacement system should be. A single-family asphalt shingle replacement here runs $9,500 – $16,500, while flat and low-slope rental roofs typically come in at $11,000 – $22,000 because of the membrane systems, scuppers, and drainage work involved.
Full Tear-Off vs. Layover
On a Lennox roof built in the 1950s or 60s, we almost always recommend a full tear-off. Laying new material over saturated underlayment is the single most common cause of recurring leaks we see here, especially on flat and low-slope rental buildings. The cheap bid that promises a re-roof without removing the old material is hiding the exact problem that’s causing your leak.
Flat and Low-Slope Systems
Most of Lennox’s rental stock sits under flat or low-slope roofs, which means the replacement conversation is about membrane systems, scupper drainage, and parapet flashing, not just shingle color. We install low-slope systems with rebuilt drain points and drip edge so each unit on a multi-unit building sheds water independently. That detail matters when one clogged scupper can send water into two or three units at once.
Asphalt Shingle Roof Replacement in Lennox
Asphalt shingle roof replacement is the most common job we quote on Lennox’s single-family homes, most of which date to the 1940s and 60s and still sit under the original or second-generation shingle roof. For a typical one-story stucco home in the 90304 zip code, expect to pay $9,500 – $14,500 for a complete tear-off and re-shingle with architectural shingles, depending on roof size, pitch, and decking condition. The coastal-influenced climate means shingles here take direct sun most of the year, so UV resistance and a proper ventilation setup are non-negotiables in our quotes.
Wind-Rated Nailing Patterns
Lennox sits close enough to the coast that wind uplift is a real factor in roof longevity. A compliant replacement has to meet the nailing pattern and fastener spec listed in the manufacturer’s wind rating documents, which the LA County inspector may ask to see. Cheap bids skip this step, and the first winter storm with real gusts is when the difference shows up as missing shingles and a denied insurance claim.
Architectural Shingle Options
We stock and install architectural shingles from Owens Corning, IKO, and Atlas, among others, so Lennox homeowners can choose the warranty tier and aesthetic that fits their budget. You don’t have to accept whatever single brand a dealer happens to carry. We’ll show you the material options side by side, with the actual warranty differences spelled out.
Trusted Brands We Service in Lennox
We install Owens Corning, IKO, and Atlas systems on Lennox roofs regularly, along with several other manufacturer lines. That breadth matters here because Lennox’s mix of flat rental roofs and shingle-roofed single-family homes often requires entirely different product families on the same street. We stock the accessories, underlayments, and flashing components for each system locally, so your replacement doesn’t stall waiting on parts from a distant distributor. When you call us, we can talk materials honestly because we’re not tied to one brand’s catalog.
Common Roof Replacement Problems We See in Lennox Homes
- Saturated underlayment hidden under old roofing: On Lennox’s flat and low-slope rental roofs, water sits longer after rain, and any small tear in the membrane soaks the underlayment below. A layover buries that moisture and the leak returns within a season or two. We cut into the roof and check before quoting.
- Failed flashing at shared property lines: So many Lennox buildings sit just feet from the next structure. The flashing along a party wall or shared parapet takes constant expansion and contraction stress, and a single failed seam can leak into multiple units at once. Replacing it properly requires pulling back the adjacent material and reseating the metal with the right sealant.
- Improper drainage on packed parcels: Tight side yards and closely spaced buildings mean drain scuppers and downspout points get overloaded during heavy winter rain. A replacement that doesn’t address scupper sizing and pitch is leaving the roof half-finished. We rebuild drainage points as part of every flat or low-slope replacement.
- Wind damage from skipped fastener patterns: Ocean-adjacent gusts test every shingle seam. We’ve seen roofs less than five years old with shingles stripped because the installer used fewer nails than the manufacturer’s wind rating requires. That’s a code violation and an insurance problem waiting to happen.

FAQs About Roof Replacement in Lennox
LA County Building & Safety issues roof replacement permits for Lennox because the area is an unincorporated county island, not a city with its own building department. We pull those permits on your behalf, schedule the inspection, and make sure the work passes before we call the job complete. Call (855) 597-2817 and we’ll walk you through the permit process for your specific property.
A Lennox roof replacement should meet the wind rating specified by the shingle or membrane manufacturer’s published installation instructions, which typically requires a specific nailing pattern and fastener count per shingle. The rating is earned by installing exactly to that spec, not by using a particular product. We document the fastener pattern and material spec on every replacement, and the county inspector verifies it during the final inspection.
A flat roof replacement quote on a Lennox rental building should include full tear-off of the existing membrane, replacement of any saturated underlayment, new membrane install per manufacturer spec, rebuilt scuppers and drip edge, and flashing replacement at all penetrations and shared walls. If a quote skips the tear-off or the scupper work, it’s leaving out the two things that actually stop leaks on a multi-unit flat roof. Call us for an itemized quote that shows every one of those components.
Start by comparing what each bid includes: tear-off or layover, underlayment replacement, flashing work, scupper and drainage rebuild, permit fees, and the specific manufacturer and product line being proposed. Then compare the warranty: a system with manufacturer-backed coverage is worth more than a vague workmanship promise. We give you a line-item bid that makes that comparison straightforward.
Yes, a documented, permit-inspected replacement gives you a record that the roof meets current county code and manufacturer spec, which matters when you file an insurance claim or review your policy. Insurers often ask for proof of roof condition and age after a weather event, and a permit-inspected replacement is the strongest documentation you can hand them. If your roof was replaced before you bought the property and you’re not sure of its history, call (855) 597-2817 and we can inspect it.
