AfterFast, Reliable Roof Replacement Across Downey
A full roof replacement on a Downey home typically runs between $12,500 and $28,000, depending on size, pitch, decking condition, and material. Most tear-offs on houses built between the 1940s and 1970s take three to five working days once permits clear. Our crews serve Downey every week, and we scope every job before signing so the number on your written estimate is the number on your invoice. Call (325) 246-5075 and we’ll walk the roof with you, no charge.
Downey’s housing stock is a specific animal. The postwar tracts off Lakewood Boulevard and Paramount Boulevard, the older blocks near Furman Park and Rio San Gabriel Park, the hillside-adjacent streets around Stonewood Center – these houses were framed a certain way and roofed a certain way, and you can’t bid them like a new build in Orange County. We know what’s under the shingles here because we’ve torn enough of them off.
Why Crestview Roofing Is Downey’s Preferred Roof Replacement Company
Crestview Roofing has replaced roofs in Downey since our founding in 2000. Homeowners across the city – from the 90241 and 90242 ZIP codes to the quieter streets near Wilderness Park – keep calling us back because we put everything in writing before the first shingle comes off. The price we quote is the price you pay. Not a number that grows when the foreman finds something under the felt paper.
Dylan Pace runs every Downey job the same way. You get the trade name of your material, the line-item cost, the permit schedule, the crew arrival window, and before-and-after photos of the work surface. No four-hour window. No phone tag. A live person answers our phones 24/7, which matters when a Tuesday morning tear-off in Downey gets rained on.
We schedule replacement work into Downey on a fixed calendar, not a “we’ll get there when we get there” basis. Our Los Angeles office coordinates dispatch, and the Downey crews know the streets, the inspectors, and the weird roof transitions on the older stucco boxes near Downey High.
Roof Replacement Contractor in Downey
A Roof Replacement Contractor in Downey does the full scope: removing the old roof down to the framing, hauling off debris, repairing or replacing the decking, installing new underlayment and flashing, then laying the shingle or membrane system with a manufacturer-backed warranty. When we act as your Roof Replacement contractor in Downey, the bid includes permit pull, passes inspection, and leaves the job site swept and magnet-raked for nails. Most full replacements in Downey run $12,500 to $28,000 depending on square footage, roof complexity, and any structural surprises under the old material.
Your roof replacement in Downey starts with a written estimate that scopes the deck before we sign anything. Not after. That’s the difference between a bid that says one thing in the driveway and another thing on the final invoice. We’re part of the Relay Home Co. family, and every job runs on The Relay Visibility Guarantee: written price before any work begins, photo documentation before and after, live trackable arrival, and a digital invoice sent by text.
Full Roof Replacement
A full tear-off is the only honest option on most Downey homes. You’re not layering new shingles over old ones and trapping the heat this city already deals with in July. You’re starting clean: new deck, new underlayment, new valley metal, new ridge cap. We price it that way from the first conversation, not as a “discovery” after the first dumpster leaves.
New Construction
Building an ADU off the garage, adding a room behind the kitchen, or doing a full ground-up build on a lot near Downey Landing? We handle new-construction roof systems from truss inspection to final cap. Same written scope, same visibility guarantee, same expectation of a clean pass on the first inspection.
Asphalt Shingle Roof Replacement in Downey
Asphalt Shingle Roof Replacement is what 8 out of 10 Downey tear-offs end with, and for good reason. Asphalt shingles hold up to Southern California sun, they install efficiently on the low-pitch ranch and mid-pitch tract roofs common from Downey’s 1940s-1970s boom, and they hit a reasonable price point. A standard architectural shingle replacement on a typical 1,300-1,800 square foot Downey home with normal decking conditions runs $13,500 to $22,500, including tear-off, disposal, permits, and a 30-year GAF, CertainTeed, or Owens Corning material warranty.
Architectural Shingles
When your Downey roof is visible from the street – which is almost every house here – architectural shingles buy you a deeper shadow line and a dimpled texture that the old flat 3-tab never had. On the ranch houses off Florence Avenue, that visual difference isn’t a luxury. It’s the difference between a roof that looks like 1987 and one that looks like it belongs on the house.
Roof Decking Replacement
This is the line item that separates a real Downey bid from a cheap one. If your home still has its original wood shake, you’re almost certainly walking on skip-sheathing – spaced 1x boards, not a solid deck. California code requires a solid, code-compliant deck before new underlayment goes down. We scope that replacement into the original bid, because we already know it’s there.
Trusted Brands We Service in Downey
We install and repair roof systems with manufacturer-backed materials from GAF, CertainTeed, and Owens Corning because these three dominate the Downey market for good reason: they hold their granules in the LA basin heat, they carry strong wind ratings, and their warranties actually pay claims. When a Downey homeowner wants a specific color or profile – a CertainTeed Landmark in charcoal, a GAF Timberline HDZ in weathered wood – we can pull samples and line up exact material availability. No generic substitutions. Roof Replacement crews working Downey stock what’s specified, order what’s not, and document every skid that shows up on your driveway.
Common Roof Replacement Problems We See in Downey Homes
- Hidden deck rot along the rakes and valleys. The old wood shake breathed a certain way, and when a previous owner roofed over it, moisture got trapped at the edges. By the time a new tear-off happens, the fascia and deck boards at the rake are often soft and need sistering before the new roof can go down.
- Bids that price only the visible shingle field. A contractor quotes the field, the cap, and a dumpster. Then the deck is rotted, and the change order shows up. We write deck repair into the original Downey bid because we’ve seen it on this exact housing stock for years.
- No ice and water shield at valleys and penetrations. Downey may not get snow, but wind-blown rain driven into an eave or a valley is real. If the original roof never had a peel-and-stick membrane under those transitions, it needs one now. Code says it, and our scope says it.
- Roofing over an existing layer to save money. On an older Downey home, a second layer of shingles traps attic heat and adds dead load to framing that was never engineered for it. The city’s summer temperatures already push those attics to 140 degrees. We don’t layer. We strip to the deck.
Pricing for Roof Replacement in Downey, CA
Here’s what a full replacement actually costs in Downey. A straight re-shingle on a small 900-1,100 square foot home with clean decking runs about $12,500 to $16,000. A typical 1,400-1,800 square foot ranch runs $14,000 to $22,000. A larger two-story, a steep pitch, or a tile-to-shingle conversion pushes $22,000 to $28,000. The single biggest variable is deck replacement: if we’re pulling skip-sheathing and laying OSB over the whole roof plane, add $2.50 to $4 per square foot of roof area. Every estimate includes the tear-off, disposal, permit, materials, and labor. Call (325) 246-5075 for a written price. You’ll get it before any work starts – that’s the rule, not the exception. And our 365-Day Done Right Promise covers every repair for a full year, including a free second visit if something fails.

FAQs About Roof Replacement in Downey
Yes. The City of Downey requires a building permit for any full roof replacement, and the permit triggers at least one inspection at the deck stage and a final at the shingle stage. We pull the permit, schedule the inspections, and pass them – this is included in every written estimate, not billed as a surprise after the fact. Call (325) 246-5075 and we’ll tell you exactly what your address triggers at the permit counter.
Line up the line items side by side: deck removal, deck replacement (per square foot), underlayment type, valley material, permit fees, disposal tonnage, and shingle brand and line. If one Downey bid is $5,000 lower, it almost always omits the deck work on an old shake roof. Ask for the written deck scope before you sign. We give it to you in the first estimate because we already know what’s under the old roof on these blocks.
If your home was built between roughly 1945 and 1975 and the current shingles are the second or third layer, there’s a good chance the original layer was wood shake on skip-sheathing. You’ll see spaced 1x boards with gaps between them once the old material comes off. That deck must be brought up to code with solid sheathing before new underlayment installs. We scope this before signing, not as a change order.
Most architectural shingles from GAF, CertainTeed, or Owens Corning carry a 110 to 130 mph wind rating when installed to the manufacturer’s spec, which is more than enough for what Downey experiences. What matters locally is proper nail pattern and the right uplift resistance at the rakes and ridges on those older roof geometries. We install to the manufacturer’s high-wind detail on every Downey replacement as standard practice.
Most complete tear-offs and replacements on a typical Downey ranch home take three to five working days from the first shingle up to the final inspection, with permit approval adding a week or two on the front end depending on the city’s current plan check queue. If deck replacement is extensive, add a day. We give you a written calendar at signing, and you get photo updates as the work progresses.
