Fast, Reliable Roof Replacement Across Covina
Roof replacement in Covina typically runs between $11,500 and $22,000 for a standard single-family home, with most mid-century ranch and tract houses landing around $14,000 to $18,000 for a full tear-off and architectural shingle install. That range shifts once we pull the old roof off, because Covina’s 1940s through 1960s housing stock hides decking and framing issues you can’t see from the ground. We’re familiar with those houses, those streets, and what tends to be waiting under the shingles. If you’re looking at a roof that’s 20-plus years old or one that just took a beating from Santa Ana winds, call (866) 650-8319 and we’ll schedule a roof inspection first, before any replacement quote is written.
Why Gable Roof Repair Is Covina’s Preferred Roof Replacement Company
Covina homeowners call us because we don’t open with a replacement pitch. That’s not our default. Our repair-first philosophy comes from experience: a lot of Covina roofs don’t need a full tear-off, and some absolutely do. We tell you which one you’re looking at only after an inspection. Neil Drummond built the company around that separation of diagnosis from sale, and it’s why Covina customers keep referring us to neighbors on their block. We work with seven shingle manufacturers – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral – so the material conversation starts with what your roof actually needs, not whatever brand we happen to be pushing that quarter. Our Roof Replacement team handles the full scope, but we’ll tell you plainly when a repair makes more sense.
Local knowledge matters here. We know the difference between a 91722 tract roof and a 91724 hillside build, and we know what the city of Covina’s building department requires once a re-roof permit is pulled. That’s not generic roofing talk. It’s the difference between a quote that holds and one that balloons three days into the job.
Styles & brands we work with
Roof Replacement Contractor in Covina
A Roof Replacement Contractor in Covina takes on the full tear-off and re-roof scope, and that’s the work we do when the existing roof has reached the end of its service life or when hidden damage makes patching a losing game. In Covina, that typically means a full replacement on a mid-century house where the original or second roof has cracked shingles, failing underlayment, or decking that’s no longer sound. This is major work, not a repair call. It involves pulling every layer down to the sheathing, inspecting and often replacing sections of decking, then rebuilding the roof system with new underlayment, flashing, shingles, and ventilation. Permit fees in Covina, inspection scheduling, and disposal costs are all part of the job, and we write them into the estimate so you’re not surprised.
Expect a full re-roof in Covina to land between $13,000 and $20,000 on most single-family homes once mid-century decking replacement and code-triggered upgrades are factored in. Smaller homes with a simple gable footprint can come in under that. Larger or steeper roofs go over.
Full Tear-Off and Re-Sheathing
We don’t install new shingles over rotted decking, and on Covina’s older houses, rotted or delaminated decking is common. When we pull the old roof and find original 1×6 skip sheathing that’s cracked or water-damaged, we re-sheath before underlayment goes down. That’s a scope change, but it’s also a structural necessity, and we’ll get your written approval before we proceed.
New Construction Roofing
For Covina homeowners building new – whether it’s a full custom build in the 91724 hillside areas or a rebuild on an older lot – we take the roof from bare framing to finished shingle field. Working with seven manufacturers means you’re not locked into one brand’s system or one price tier.
Asphalt Shingle Roof Replacement in Covina
Asphalt Shingle Roof Replacement in Covina is the most common re-roof we do, largely because the city’s postwar housing stock was built for it. The majority of homes in 91722 and 91723 have low-pitch or moderate-pitch gable roofs sized for asphalt shingle systems, and when those original roofs hit 25 to 30 years, the shingles are typically granule-bald, cracked, and losing their wind rating. A standard architectural shingle replacement in Covina runs $12,000 to $17,000 on a typical 1,400 to 2,000 square foot house, including tear-off, underlayment, shingles, flashing, and new drip edge. Upgrading to a premium shingle line pushes it higher.
Architectural Shingle Systems
Most Covina homeowners choose architectural shingles for the next roof because they carry a higher wind rating than the old three-tab they’re replacing. Wind rating only holds if the installation matches it, though. On older Covina houses, the nailing pattern behind those shingles matters just as much as the shingle itself, and that’s where installation quality separates a roof that lasts from one that fails in the next Santa Ana season.
Decking Replacement and Flashing Work
Decking is the foundation under the shingle field, and Covina’s older homes often need sections replaced once we tear off. We also replace all flashing at valleys, walls, chimneys, and penetrations rather than reusing old metal. Flashing is where leaks start on mid-century homes, and reusing it on a new roof is a false economy.
Trusted Brands We Service in Covina
We install and service roofs from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, which means your Covina home gets the material that fits its pitch, exposure, and budget – not the one brand we happen to stock. If your current roof is GAF and you want to stay with GAF, we’ll quote it. If CertainTeed’s wind-rated architectural line fits your Santa Ana exposure better, we’ll quote that. We work with your roof’s brand, not ours. Material availability for Covina jobs is handled through our supply channels, and we’ll tell you upfront what’s in stock and what has a lead time. Seven brands, one standard of installation.

AfterCommon Roof Replacement Problems We See in Covina Homes
- Deteriorated original decking on mid-century tract houses. Homes built in the 1940s through 1960s around 91722 and 91723 often have 1×6 skip sheathing that’s cracked or delaminated after decades of heat cycling and occasional water intrusion. We don’t know until tear-off, which is why our estimates include a written allowance for likely decking replacement.
- Failed flashing at valleys and penetrations on low-pitch roofs. Covina’s inland heat dries and cracks sealants faster than coastal LA, and the low-pitch geometry on many older homes means water hangs around flashing longer. By the time a roof is due for replacement, the flashing is usually shot.
- Santa Ana wind damage on older nailing patterns. The first generation of architectural shingles on Covina roofs often wasn’t nailed to the manufacturer’s wind-rated spec. After a few hard Santa Ana seasons, shingles lift, tear, or lose their seal strip, and the whole field needs to be redone.
- UV-degraded built-up flat sections on 1940s and 1950s homes. Many Covina houses have flat or low-slope sections – over additions, porches, or carports – that were built-up roofs. Inland heat bakes these membranes faster than coastal climates, and by the time the main roof goes, the flat sections are usually checked and leaking too.
Because Covina’s original 91722 and 91723 blocks are still largely on their first or second roof, tear-offs here tend to fail in clusters. A single Santa Ana wind season or first hard winter rain can put an entire mid-century street into simultaneous leak calls, which means scheduling and decking-delivery logistics matter as much as the shingle spec. That’s a Covina-specific reality we plan for, and it’s why we don’t treat every city’s re-roof the same way. Nearly all of Roof Replacement in Covina that we handle includes some level of framing or decking repair once the old roof comes off, because these houses are all hitting the re-roof window at roughly the same time.

FAQs About Roof Replacement in Covina
Because the decking and framing underneath mid-century Covina roofs are often in worse shape than the shingles above them suggest. Your quote changes only if we find something during tear-off that couldn’t be seen before – rotted decking, damaged rafter tails, or failed flashing hidden under old layers. We handle this by writing an allowance into the contract before we start, and we get your written approval on any pricing adjustment before we proceed. Call (866) 650-8319 to see how we structure an estimate so you’re never surprised mid-project.
Yes, Covina requires a building permit for a roof replacement, and it triggers a city inspection before final approval. On older homes, the permit can also trigger code upgrades – most commonly adding or verifying attic ventilation, confirming the roof-to-wall connections meet current wind standards, and sometimes bringing the decking up to nailing spec. We pull the permit, schedule the inspection, and build these items into the estimate upfront.
That’s a familiar pattern in Covina’s older neighborhoods. The original roofs on mid-century tract homes were installed around the same time, so they fail around the same time. A hard Santa Ana wind season lifts shingles and breaks seal strips on roofs that were already near the end of their service life, and suddenly every house on the block has a leak. If your neighbors are re-roofing, your roof is likely not far behind. Call (866) 650-8319 and we’ll inspect yours before the next wind event.
Architectural shingles are the right call for most Covina homes, but the wind rating only holds if the installation matches the manufacturer’s spec. On low-pitch roofs, that often means a different underlayment requirement, and on older homes, it means the nailing pattern has to be upgraded from the original. We inspect the roof-to-wall connections and decking condition before quoting, and we’ll tell you honestly whether architectural shingles make sense on your specific roof geometry. Call (866) 650-8319 for a straight answer on your roof.
We write line-item estimates with the same categories any homeowner can compare across contractors: tear-off and disposal, decking allowance, underlayment, shingle material with brand and product line named, flashing, ventilation, permit fees, and labor. If a competitor’s quote is missing the decking allowance or the permit line, you’re not comparing the same job. We’d rather show you the full scope up front than win a bid with a low number that moves later. Call (866) 650-8319 for a free estimate you can actually compare.
On a postwar tract house off a mid-century 91723 street, our crew pulled the second-layer three-tab down to original 1×6 skip sheathing and found two rafter tails softened where a valley had been leaking behind the old flashing for years. We sistered the damaged framing, added ice and water shield through the valleys and at penetrations, then set a new Owens Corning architectural shingle field over fresh underlayment with a ridge vent and new drip edge – and the homeowner approved the framing repair in writing before we nailed a single shingle. That’s how we handle every Covina roof replacement: inspection first, recommendation second, and no scope change without your signature.
