Fast, Reliable Roof Replacement Across Rossmoor
Roof replacement in Rossmoor typically costs between $14,000 and $32,000 depending on size, material, and what we find under the old roof. Most jobs take 3 to 7 working days once the architectural review clears. If you’re calling from Rossmoor, you’re likely dealing with an original 1960s wood shake roof that’s finally given up, or a composition shingle roof that’s baked past its useful life. We know these homes. We know the skip sheathing underneath them, the low-slope additions, and the HOA rules that govern what you can put back on. Call (562) 512-7366 for a written price before any work starts.

Why Birchbark Roofing Long Beach Is Rossmoor’s Preferred Roof Replacement Company
Rossmoor homes are different from what we see in most of Orange County. The original 1950s through 1970s construction means roof decks were built with skip sheathing, not solid plywood. That changes how a replacement has to be done. Our crews work in Rossmoor regularly and know the street patterns, the lot sizes, and the way the county inspection office operates for unincorporated areas. We coordinate tear-off around the architectural committee’s calendar so your home never sits exposed to a Santa Ana wind or a winter rain front. Homeowners here appreciate that we name what will be protected before we start: shoe covers at the door, drop cloths through the hallway, all debris cleared and photographed before we leave. That’s the Cedarwell Care Promise, and it’s stamped on every Birchbark job.
We’re part of the Cedarwell family of roofing companies, independently owned and operated since 2000. Erik Lindgren leads our team, and every replacement carries the 365-Day Done Right Promise. If the work isn’t right, we make it right. You’ll also get a written price in dollars before the first shingle comes off, which matters on a big-ticket project like this. Call (562) 512-7366 any time; a live person answers 24/7.
Styles & brands we work with






Reroofing in Rossmoor
Reroofing in Rossmoor means removing the old roof down to the framing and rebuilding the entire system: underlayment, decking where needed, flashing, drip edge, and new shingles or shakes. It’s not a layover. A layover hides what’s underneath, and on these 1960s homes, what’s underneath is usually the problem. Most full reroofing projects in Rossmoor run $16,000 to $30,000 including tear-off, decking repair, underlayment, and new roofing material. You’ll see your exact number in writing before we start.
Addressing Hidden Decking Rot
The original wood shake roofs on Rossmoor ranches were installed over skip sheathing: spaced 1×6 boards with gaps between them. Fifty-plus years of salt air and occasional rain seeping through cracked shakes rots those boards silently. We find dry rot along eaves and chimneys on nearly half the tear-offs we do here. Replacing it adds $2,000 to $6,000 depending on how much is compromised, and adds one to two days. We’ll walk you through it with photos before any additional work is approved.
Scheduling Around Rossmoor’s Architectural Review
Rossmoor’s architectural standards mean your roof replacement has to be submitted and approved before the first shingle is ordered. We prepare the full submittal packet: material samples, color options, roof profile changes if any, and work schedule. Review typically adds one to three weeks. We plan the tear-off date for immediately after approval so there’s no gap between demolition and dry-in.
Flat Roof Replacement in Rossmoor
Flat Roof Replacement in Rossmoor most often happens on the 1970s additions and enclosed patios attached to the original ranch homes. These low-slope sections fail differently than pitched roofs: ponding water, seam separation, and rusted edge metal. A flat roof replacement here typically runs $9,000 to $18,000 depending on square footage and whether we’re tearing off a built-up roof or a single-ply membrane. The job takes two to four days.
Ice and Water Shield on Low-Slope Sections
Wherever the pitch drops below 3:12, we install ice and water shield across the entire surface – not just at the eaves. This is mandatory in our book, and it’s a common point of confusion when homeowners compare quotes. Some crews skip it on flat sections to lower the bid. We don’t. Heavy winter rain against those valley intersections will find every gap. The shield is what keeps the interior dry.
Matching the Original Mid-Century Profile
Flat roof additions on Rossmoor homes were usually designed with specific edge details and parapet heights. Changing that profile can trigger a re-review by the architectural committee. We match the original details whenever possible, and when you need a material change, we include the samples and spec sheet in the submittal so it’s approved before we start.

Trusted Brands We Service in Rossmoor
We work with GAF, CertainTeed, Owens Corning, IKO, and Atlas materials and keep a strong stock of architectural shingles, underlayment, and flashing in our local supply channels, so Rossmoor replacements aren’t delayed waiting on shipped product. If you want CertainTeed Presidential Shake to echo the original wood shake look but with a fire rating and a warranty, we can price it. If you’d rather have Owens Corning Duration in a mid-century palette, we’ll get samples to you fast. Every material choice goes into the architectural submittal, so the committee sees exactly what’s going on the roof.

AfterCommon Roof Replacement Problems We See in Rossmoor Homes
- Original wood shakes over rotted skip sheathing. The 1960s shake roofs look weathered but intact from the ground. Once we tear off, the spaced boards underneath are often crumbling. You’ll get a photo of every bad section before any decking is replaced.
- Layover roofs that failed inspection. Some Rossmoor homeowners had a cheap re-nail done years ago. The new material changes the roof profile, and Rossmoor’s architectural standards reject it when the profile shifts. We replace it properly, full tear-off, so it passes.
- Color mismatches with the mid-century palette. Rossmoor’s HOA has a defined palette of approved colors. Picking the wrong shingle color means a stop-work order while new samples are submitted and approved. We bring the approved color board to the estimate and match from it.
- Leaks at the flat-roof valley intersections. The 1970s flat additions tie into the main roof at shallow valleys. Without ice and water shield, that seam leaks during the first heavy winter storm. We install shield full-width on every low-slope section.

FAQs About Roof Replacement in Rossmoor
It typically adds one to three weeks, depending on whether the committee needs clarification or additional samples. We file the submittal as soon as you approve the material choice, and we schedule your tear-off to begin right after approval comes through, so the review time doesn’t leave your roof open to weather. Call (562) 512-7366 and we’ll walk you through the current review calendar.
You don’t have to be home, but you will get a call and photos before anything changes. We stop work when we find rot, document it, and send you images along with a written change-add for the additional decking replacement. Nothing gets approved or added to your bill without your written go-ahead. We’ll coordinate the county inspection on the new decking as part of the job.
Rossmoor’s architectural committee approves a mid-century palette of charcoal, greys, browns, and muted earthen tones. Bright or highly variegated colors usually get rejected. We bring the approved color board to your estimate and match samples directly to it, so the submittal passes the first time. If you’re not sure what’s allowed on your street, call us and we’ll check the specific restrictions for your lot.
Yes. We prepare and file the entire packet: material specs, shingle samples, color confirmation, roof profile notes, and project schedule. You just sign. This is one of the biggest differences between us and an out-of-area crew that doesn’t know Rossmoor’s rules. Call (562) 512-7366 and we’ll start the submittal before we even order materials.
Because the low-slope sections on those 1970s additions need full-width ice and water shield to survive winter rain and coastal moisture. It’s not an upsell; it’s the difference between a roof that leaks at the first storm and one that stays dry. Some contractors leave it off to lower the bid. We’d rather give you the honest number up front. Call (562) 512-7366 for a written, itemized quote that includes everything your roof actually needs.
