Fast, Reliable Roof Replacement Across Citrus
A full roof replacement in Citrus typically runs between $12,000 and $28,000 for a standard ranch or bungalow, with flat roof sections adding $8 to $12 per square foot. Most jobs take 3 to 7 working days once permits clear through LA County Building and Safety. If your roof is at the end of its life or the shingles are lifting after another Santa Ana season, call (424) 766-4937 and we’ll walk the property with you, measure everything, and hand you a written price before any work starts.
We know Citrus well because we work here constantly. The unincorporated county side of the San Gabriel foothills has its own permitting path, its own fire-code requirements, and its own set of roof problems that you will not see 25 miles west. We plan every Citrus job around those conditions from the first measurement, not after the tear-off starts.
Why Birchbark Roofing Is Citrus’s Preferred Roof Replacement Company
Citrus homeowners call us because we show up knowing the difference between a county inspection and a city inspection, and we quote the job for what it actually is: a Class A fire-rated assembly permitted through LADBS, not a generic shingle swap. That specific local knowledge saves homeowners from re-quotes, stop-work orders, and surprises at inspection. Our Roof Replacement team includes technicians who have torn off and rebuilt roofs from Citrus Avenue up toward the mountain interface streets, so the conditions on your specific block are not new to us.
Every job is led by a background-checked, uniformed technician. You will know who is walking onto your property before they arrive. Shoe covers go on at the door, drop cloths go down through the hallway, and the crew photographs the completed clean-up before they pull away. If your dog needs to stay inside during tear-off, we coordinate the door schedule with you. If you have kids playing in the yard, we stage materials and dumpsters where they will not wander into the work zone. These are not extras. They are part of how we run a Citrus roof replacement, on every single job.
Birchbark Roofing is part of the Cedarwell family of roofing companies since 2000, with each location independently owned and operated. Every replacement carries our 365-Day Done Right Promise: if the work is not right, we make it right. That promise is stamped on your job file, and Erik Lindgren, the owner, stands behind it.
Flat Roof Replacement in Citrus
Flat Roof Replacement in Citrus is a different job than the pitched shingle work most roofing companies lead with, and it is common here because so many mid-century ranch homes and bungalows have low-slope or nearly flat rear additions, carports, and detached structures. On a flat or low-slope section in Citrus, a replacement usually involves tearing off the old membrane or built-up layers, inspecting and often replacing the sheathing underneath, repairing any sag or ponding points, and installing a new membrane system, typically with tapered insulation to restore positive drainage. In Citrus, flat roof replacement runs $8 to $12 per square foot, so a 300-square-foot rear addition flat section typically lands between $2,400 and $3,600 before any decking replacement.
Built-Up and Membrane Systems
On older Citrus homes, flat sections were often built-up roofs: layers of felt, asphalt, and gravel over wood decking. When those layers fail, water ponds and finds the seams. We tear off to the decking, check the framing for rot, and install a modern membrane system, usually with a Class A fire-rated cap sheet if the structure sits within the foothill hazard zone.
Decking and Drainage
Flat roofs fail most often at the low points. If the original framing has sagged or the scuppers are undersized, we correct the slope before laying anything new. On Citrus lots with open acreage and older outbuildings, we regularly find flat sections that were never properly drained in the first place. That gets fixed during the replacement, not ignored.
Roof Installation in Citrus
Roof Installation in Citrus covers new construction, additions, and full tear-offs where the sheathing and framing are exposed and built back from scratch. Whether it is a new ADU going up on an acreage lot, a detached shop, or a full replacement where the decking is too far gone to salvage, the process in Citrus starts with a county permit and a fire-code review. A full new roof installation on a standard Citrus ranch home runs $14,000 to $25,000, depending on square footage, pitch, and whether we are adding new sheathing. New construction and ADU roof installation runs $10 to $14 per square foot for a complete assembly with Class A materials.
New Construction and ADUs
Citrus has a growing number of detached ADUs and shop structures going up on existing acreage lots. We install the roof assembly to the same fire-rated standard as the main house, with an eye on how the ADU’s roofline ties into the main structure at the valleys, because that is where wind-driven rain and embers collect. We also stage the material drops and dumpster placement around whatever else is happening on the lot, so the build stays moving.
Full Tear-Off and Re-Deck
When the existing roof has been re-covered once or twice, or the sheathing under an old shake roof has softened, the right installation is a tear-off to framing. We strip everything, inspect the rafters, replace damaged sheathing with code-compliant material, and build the new assembly up from there. On a Citrus home that has never had the original 1950s or 60s decking replaced, this is where hidden rot gets found and fixed before it becomes structural.
Trusted Brands We Service in Citrus
We install and service roofing systems from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Citrus homes in the Very High Fire Hazard Severity Zone, we commonly spec GAF’s Class A shingle assemblies and Atlas fire-rated systems, and for flat sections we favor Boral’s fire-rated cap sheets. Because Citrus sits close to our Los Angeles dispatch and supply coordination, we can have materials staged on your lot quickly once permits clear. We do not push a single brand; we write the spec for your roofline, your fire-code requirements, and your budget, and you see the exact product names and line-item pricing in writing before you sign anything.
Common Roof Replacement Problems We See in Citrus Homes
- Ember intrusion at ridge vents and boxed eaves. On the upper streets of Citrus nearest the mountain interface, wind-driven embers do more damage than direct flame. We inspect and seal ridge vents and boxed eaves with ember-resistant mesh as a standard part of any replacement in the hazard zone.
- Fastener pull-out after Santa Ana wind events. The San Gabriels funnel fall winds hard through Citrus, and a lifted shingle edge is a fast path to a blown-off section. We re-nail and seal every edge course during replacement, and we check the fastening pattern on the old roof to understand what was failing.
- Poor ventilation on mid-century low-slope rooflines. Homes built in the 1950s and 60s often have little or no attic ventilation, which bakes the decking in foothill heat and accelerates sheathing rot. We correct intake and exhaust ventilation during replacement so the new decking does not fail the same way.
- Re-covered old wood shake. Many Citrus homes still carry the original wood shake with a once-over composition layer on top. That hidden second layer complicates the tear-off, adds disposal weight, and often hides rot at the valleys. We tear off to the decking and rebuild from a clean substrate.
Pricing for Roof Replacement in Citrus, CA
A standard composition shingle roof replacement on a Citrus ranch home runs $12,000 to $18,000 for a typical 1,500 to 1,800 square foot roof. Larger homes and those with multiple roof planes, flat sections, or steep pitch run $18,000 to $28,000. Flat roof replacement on a rear addition or detached structure adds $8 to $12 per square foot. If the old roof is a re-covered shake that requires a two-layer tear-off and full re-deck, expect the higher end of the range. If your lot has open acreage with long material hauls, tight equipment access, or septic and well setbacks that limit staging, we scope those before quoting so the price you see is the price you pay. Call (424) 766-4937 for a free estimate. You will get a written line-item price, not a range over the phone.

FAQs About Roof Replacement in Citrus
If your property sits inside the Very High Fire Hazard Severity Zone, which covers most of upper Citrus, you legally need a Class A fire-rated roof assembly permitted through LA County Building and Safety. A cheaper shingle assembly that passed in an incorporated city next door does not meet code here. We check your parcel’s hazard zone status before we quote, and we spec the assembly to the county’s standard. Call (424) 766-4937 and we will look up your property while you are on the phone.
Because Citrus is unincorporated LA County, your roof replacement permit is pulled through LA County Building and Safety’s unincorporated division, not through any city hall. Inspections are scheduled with the county, and the inspector is enforcing county fire and building codes, including the Class A requirement for properties in the hazard zone. We handle the permit application and the inspection scheduling as part of the job.
Yes, it changes the quote because each structure needs its own scoping. We measure the shop and the ADU separately, check their slopes and decking conditions, and factor in the additional material runs and dumpster capacity. You will see each structure as a separate line item in the written price, not bundled into a blurry total. Call (424) 766-4937 and we will walk the whole lot with you, outbuildings included.
It means the existing roof likely has two layers: the original wood shake under a once-over layer of composition shingles. That is a full tear-off to the decking, not a shingle-over. We strip both layers, replace any rotted sheathing, rebuild the valleys with ice and water shield, and install the new Class A assembly from a clean deck. It costs more than a single-layer tear-off because of the extra disposal weight and the hidden damage we almost always find underneath.
Yes. On any Citrus home in the foothill hazard zone, we install ember-resistant mesh over ridge vents and boxed eaves as a standard part of the replacement. Ember intrusion through those openings is the primary ignition path in this area, not direct flame contact. We treat that detail as part of the job spec, not an upsell you have to ask about.
