Fast, Reliable Roof Replacement Across Temple City
Roof replacement in Temple City means tearing off 40 to 70 years of layered roofing on 1940s and 1950s ranch homes, most of which have low-slope or flat sections that have never been properly re-decked. We replace those roofs the right way: full tear-off to the sheathing, code-correct re-decking where the framing demands it, and a new membrane or shingle system installed over a clean substrate. If you’re dealing with a cracked built-up roof, ponding water, or granule loss from decades of San Gabriel Valley sun, call us at (866) 942-4187. We’ll inspect it, tell you exactly what you’re dealing with, and give you a line-item quote that doesn’t fall apart once tear-off begins.
Orange County Roofing Co has been replacing roofs on Temple City’s mid-century homes long enough to know what’s under them. We carry seven major shingle and low-slope brands, so the recommendation you get is based on your roof, not on what we happen to stock that month.
Why Orange County Roofing Co Is Temple City’s Preferred Roof Replacement Company
Homeowners in Temple City call us for the same reason they call a mechanic who’s worked on their exact model of car: we know the houses here. The 1940s minimalist traditionals south of Las Tunas Drive, the 1950s ranches near Live Oak Avenue, the 1960s tracts that push up against Rosemead and Arcadia – they all have specific roof conditions. We’ve torn off hot-mop built-up roofs on Trecany Avenue, El Monte Avenue, and the streets around Temple City High, and we know what to expect when the layers come off.
One thing that sets us apart locally: we don’t bid a Temple City roof replacement off the top layer. We scope for what’s underneath. That changes pricing, but it keeps the quote honest. Kurt Hensley, who leads our team, insists that every Temple City estimate includes an explicit sheathing contingency because he’s seen too many homeowners get handed a change order for re-decking after the tear-off starts.
And we don’t treat roof inspection as a sales pitch. If your Temple City roof needs an objective assessment before you decide anything, we schedule a standalone inspection. You get a written report with photos, measured wear, and a repair-versus-replace recommendation. No obligation to use us for the work.

Flat Roof Replacement in Temple City
Flat Roof Replacement is the bread-and-butter roofing job in Temple City because so many of the city’s original 1940s – 1960s homes were built with low-slope or flat sections finished in hot-mop asphalt or built-up roofing. We replace these systems by tearing off every layer down to the structural deck, repairing or replacing rotted framing, re-decking to solid plywood where needed, and installing a new low-slope roofing assembly with positive drainage so water stops ponding. A typical flat roof replacement in Temple City runs $14,000 – $22,000 for a standard single-story ranch depending on roof size, number of layers to remove, and decking condition. Full tear-off with re-decking puts it at the higher end.
Built-Up Roof Tear-Off and Re-Decking
Most flat roofs in Temple City carry two or three generations of hot-mop asphalt, and the original decking underneath is often 1×6 skip sheathing that was never meant to carry modern roofing systems. Once we strip the layers, that skip sheathing frequently fails inspection because the gaps between boards can’t support a warrantable membrane. That’s why our Temple City flat-roof quotes include a sheathing contingency line. If the decking is solid, you don’t pay that line. If it’s not, you already know the cost.
Ponding and Drainage Correction
Low-slope roofs in Temple City were built with minimal slope to begin with, and 60 years of settling hasn’t helped. We regularly see roofs off Elm Avenue and Baldwin Avenue where water stands for days after a storm, which accelerates membrane breakdown and causes leaks at penetrations. Correcting drainage – whether through tapered insulation, new crickets, or reframed scuppers – is part of the replacement work, not an add-on.
Roof Installation in Temple City
Roof Installation in Temple City means more than nailing shingles over old felt. For a 1950s ranch that’s never been properly re-roofed, it’s a full assembly: tear-off to decking, sheathing repair or replacement, ice and water shield through valleys and at eaves, new underlayment, new flashing at every penetration, and a shingle or low-slope system chosen for this specific roof. A complete architectural shingle installation on a typical Temple City ranch home runs $18,000 – $28,000, and low-slope or flat installations run $14,000 – $22,000 as noted above. The spread comes down to decking condition, number of layers, roof complexity, and which of our seven brand lines you select.
Architectural Shingles for Temple City Ranches
Temple City’s single-story ranch homes look right with an architectural shingle that adds dimension without requiring a steep pitch. Owens Corning and IKO both make architectural lines we install regularly here. They hold up better under the valley’s prolonged sun exposure than older three-tab designs, and they come with strong manufacturer warranty backing when installed to spec.
Decking and Substrate Work
The decking is where a Temple City roof installation succeeds or fails. We don’t layer new roofing over rotted or questionable sheathing. If the existing deck is solid 1/2-inch plywood or OSB and passes inspection, we proceed. If it’s original skip sheathing or has water damage around the existing penetrations, we re-deck. That’s a cost we identify in the quote so you’re never surprised mid-job.
Trusted Brands We Service in Temple City
We’re authorized to install Atlas, IKO, Owens Corning, and several other major roofing lines, and that access changes what we can recommend. If a Temple City homeowner needs a flat-roof system with a strong manufacturer warranty, we can quote it. If a neighbor wants a dimensional shingle at a different price point, we can quote that too. You don’t get steered to one brand because we carry one brand. You get the material that fits your roof, your budget, and the warranty tier you want – and it’s installed by a crew that works on Temple City roofs every week.

AfterCommon Roof Replacement Problems We See in Temple City Homes
- Multiple buried hot-mop layers. Homes built in the 1950s often have two or three layers of built-up roofing sitting on top of the original. Bidding that job without accounting for the added tear-off labor and disposal is how cheap quotes happen. We scope for every layer before we quote.
- Original 1×6 skip sheathing under the old roof. Once the built-up roof comes off, that skip sheathing can’t carry a new membrane or achieve the flat, solid surface manufacturers require for warranty coverage. Re-decking to plywood is the fix, and we include it as a contingency so the number doesn’t move on you.
- Ponding water and failed drainage. Low-slope sections around Temple City hold water after rain because the original built-up drainage was marginal to begin with. Standing water shortens membrane life and finds its way through seams and penetrations. Replacement is the time to correct the slope, not just cover the old problem.
- Sun-baked asphalt and granule loss. The San Gabriel Valley sun is rough on exposed roofing. We see cracked blisters and bare asphalt on south-facing slopes all over town, and once the granule layer goes, the waterproofing under it is next. A pre-rain inspection catches this early.
Pricing for Roof Replacement in Temple City, CA
If you’re pricing a full roof replacement in Temple City, plan for $14,000 – $28,000 on a typical single-story ranch. Flat and low-slope replacements run $14,000 – $22,000. Steep-slope architectural shingle replacements run $18,000 – $28,000. The two biggest cost drivers here are the number of layers to tear off and the condition of the roof decking underneath. Homes that have never had their original built-up roof removed almost always need decking work, and that’s exactly why our Temple City quotes include a sheathing contingency line. We also pull permits and coordinate the inspection so the job passes the city’s visible-roof-condition standards the first time. Call (866) 942-4187 for a free, itemized estimate on your specific roof.

FAQs About Roof Replacement in Temple City
Because you can’t see the decking until the old roof is off, and most Temple City homes built from the 1940s through the 1960s have original 1×6 skip sheathing under their built-up roofs. That sheathing often can’t support a warrantable modern membrane or shingle assembly, so re-decking is frequently required. Rather than surprise you with a change order, we write the sheathing line into the quote. If the decking is solid, you don’t pay it. If it’s not, you already know the cost. Call (866) 942-4187 and we’ll walk you through how this applies to your home.
The permit is for the roof replacement itself, not the material type, and Temple City enforces building code on visible roof condition. Any full replacement – flat or sloped – requires a permit and inspection. What changes is the scope of the work on the permit application: a flat-roof replacement that involves re-decking and drainage correction is a larger scope than a simple shingle overlay, and it’s written up accordingly. We pull the permit, schedule the inspection, and make sure the job passes. Call (866) 942-4187 for a quote that includes the full scope.
Tear everything off to the structural deck. There’s no shortcut. The old built-up layers and any rotted sheathing come off, the original skip sheathing is replaced with solid plywood where needed, the deck is dried in with ice and water shield through the valleys and at the eaves, and then a modern low-slope assembly is installed over the corrected deck. That’s what we did on a 1950s ranch off Live Oak Avenue where we stripped three hot-mop layers and found original 1×6 skip sheathing. We re-decked, laid ice and water shield through the valleys, and set a new flat-roof assembly with fresh drip edge. The result is a roof that can actually carry a manufacturer warranty. Call (866) 942-4187 to get your roof to the same point.
Before the November rains hit, check for cracking, blistering, and granule loss on any exposed asphalt or built-up surfaces. On a nearby Elm Avenue home, a pre-rain inspection caught blistering and granule loss near the penetrations, so we scheduled a dry-season replacement before the rains arrived. Low-slope sections with ponding water, rusted flashing around vents and pipes, and any soft spots you can feel underfoot are all warning signs. A standalone inspection costs less than a leak repair. Call (866) 942-4187 to schedule one.
Yes, roofing is measured in squares – one square is 100 square feet – but we don’t quote solely on squares. In Temple City, the square count tells you the area of new roofing. What it doesn’t tell you is how many layers you’re tearing off, whether the decking is solid or needs re-decking, and what the drainage correction requires. Those items change the price as much as the square footage does. That’s why our quotes are line-itemed, so you can see exactly what you’re paying for. Call (866) 942-4187 for a free estimate measured to your roof, not to a formula.
