Fast, Reliable Roof Replacement Across Covina
Roof replacement in Covina runs $9,800 to $22,400 for a typical 1,200 – 2,200 sq ft single-family home, with most full reroofs landing between $12,000 and $18,000 once tear-off, decking repair, and permit work are priced in. We work throughout Covina’s 91722, 91723, and 91724 ZIP codes, and we know exactly what opening up an older tract roof here turns up. Two layers of dried shake over the original deck, failed valleys, and flashing patches that quit working a decade ago. Call (866) 282-5070 and we’ll tell you what your roof actually needs, not what’s easiest to sell.

Why Buena Park Roof Repair Is Covina’s Preferred Roof Replacement Company
We’re not a general contractor dabbling in roofing. We do three things: repair, replacement, and inspection. That focus matters when you’re standing in a Covina living room asking whether the 1962 original shake over your head needs to come off or just needs targeted work. Our inspection process is built to distinguish one from the other, so you never get pushed into a full replacement when a repair would hold for years. Rick Dunnigan has built the company around that repair-first standard, and it’s why Covina homeowners call us back when the second or third roof on the block needs attention.
We also work with seven major shingle manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That means when we match a partial reroof on a Covina tract home to the existing field, we’re not forcing one brand’s color line onto your roof. We pull from whatever manufacturer actually matches. For a city full of post-war and mid-century housing where curb appeal and resale value ride on a clean, consistent roofline, that matters more than most roofers admit.

New Roof Installation in Covina
New roof installation in Covina usually means one of two things: a full tear-off and reroof on an existing home, or a fresh roof on new construction. For the existing-home market that dominates Covina’s 91722 and 91723 tracts, the work starts with removing every layer down to the deck, inspecting what’s underneath, then building back up with new underlayment, flashing, shingles, and ventilation. A straightforward tear-off and new architectural shingle roof on a 1,500 sq ft Covina home typically runs $11,000 to $16,000. If the decking is shot, add $2,000 to $4,500 for repairs.
Full Tear-Off and Replacement
Most Covina homes built between 1955 and 1975 are on their second or third roof layer. Some are still on original wood shake with composition nailed over it. A full tear-off gets everything off, exposes the deck, and lets us fix what’s rotted before it spreads. We pull permits and inspect the deck for shear nailing, because Covina’s older tract stock often fails current fastener requirements once the roof is opened.
New Construction Roofs
New construction roofing in Covina is a smaller piece of the market, mostly ADUs and occasional infill lots near downtown. We handle those with the same manufacturer selection and the same written scope as our reroof work. If you’re building near Citrus or Badillo, we’ll spec the roof to the plans and price it line by line before the first delivery.
Reroofing in Covina
Reroofing in Covina is the bread and butter of this trade, and it almost never means slapping a new layer over the old one. It means pulling off what’s there, finding what’s broken underneath, and rebuilding it properly. On a 1960s tract home off Badillo near Citrus, our crew pulled two layers of dried, curled shake and the composition layer nailed over it, and found soft decking at the valleys and at several penetrations where the flashing had been patched twice over the decades. We priced the decking repair and a new ice and water shield in the valleys in writing before any underlayment went down, then set new architectural shingles with a proper starter strip, drip edge, and ridge vent. The homeowner approved the addendum in the driveway before the first square went on.
Tear-Off of Multiple Layers
Covina’s reroof jobs are routinely two layers deep. The shake goes on in 1962, the composition goes over it in 1989, and now both have to come off. That doubles the tear-off labor and disposal, and it’s the single biggest reason a Covina reroof quote moves once the roof is opened. A two-layer tear-off on a 1,500 sq ft home adds $1,800 to $3,200 over a single-layer job.
Decking and Structural Repair
Once the old layers are off, we walk the deck with the homeowner or send photos if you can’t be there. Rotted plywood at valleys, dried-out boards around vents, and water-damaged edges at the eaves are common in Covina’s older tracts. We price decking replacement per sheet, in writing, before any new roof goes down.

Trusted Brands We Service in Covina
We’re authorized to install and warranty products from seven manufacturers, and when we work in Covina we spec the brand that fits the house and the homeowner’s priorities. Owens Corning architectural lines hold up well under the San Gabriel Valley’s dry inland UV. IKO and Atlas give solid mid-range options where budget drives the decision. Tamko’s color range works well when we’re matching a partial reroof to an existing field and preserving the roofline’s consistency. You choose the material, not us. We’ll show you the differences in cost, life expectancy, and warranty, then you decide.

AfterCommon Roof Replacement Problems We See in Covina Homes
- Two-layer shake-over-composition tear-offs. The original 1950s-60s shake gets covered with a second layer in the 80s or 90s, and now both have to come off. That exposes rotted decking and failed valleys that an overlay bid never accounted for.
- Inland thermal cycling and UV damage. Covina sits east of the coastal marine layer, so roofs take heat and sun without the moisture buffer Los Angeles gets. Shingles and shake here dry out, crack, and shed granules faster than coastal roofs.
- Permit-triggered code upgrades. Once a Covina reroof permit is pulled and the old layers come off, the deck must be re-nailed to current shear requirements, bathroom and kitchen vent penetrations corrected, and ice and water shield added at valleys. These fixes surface only after demo starts.
- Failed valleys and flashing on foothill-adjacent homes. Covina’s position near the foothills adds wind-driven rain and occasional ember exposure, which stresses valley flashing and roof penetrations on the north and east sides of homes in 91724.

FAQs About Roof Replacement in Covina
We won’t overlay a third layer on a Covina roof with two layers already in place. The weight’s too much, the deck’s too old, and the shake underneath is already curling and splitting. We recommend a full tear-off, which lets us fix the decking and valleys properly. Call (866) 282-5070 and we’ll give you the straight answer on your specific roof.
Because Covina’s post-war tract roofs hide their damage under multiple layers. Rotted decking, failed patch jobs at vents, and valley framing that’s been wet for a decade all surface only after the old shake and composition come off. We price those fixes per sheet or per linear foot in writing, and you approve the addendum before any new work starts. (866) 282-5070 for a quote that accounts for what’s actually under your roof.
We give you a written line-item quote: tear-off, disposal, decking repair allowance, underlayment, flashing, shingles, ventilation, and permit fees. That way you can compare our number against other Covina roofers’ numbers apples to apples. A typical Covina reroof priced this way runs $11,000 to $18,000. Call (866) 282-5070 and ask for the line-item breakdown.
Current Code requirements for Covina reroofs include re-nailing the deck to shear standards, correcting vent penetrations, adding ice and water shield at valleys, and sometimes upgrading attic ventilation. These are required once the old roof is opened, and we build them into the quote so they’re not a surprise. (866) 282-5070 to get a quote that includes permit work.
We install metal valley flashing and ice and water shield membrane at every valley, plus new flashing at all penetrations: vents, pipes, and any chimney. Covina’s foothill-adjacent homes get wind-driven rain that finds old flashing fast, so we don’t reuse old metal. Call (866) 282-5070 for a free estimate on a full reroof with proper valley work.
