Fast, Reliable Roof Repair Across North Tustin
Roof repair in North Tustin usually costs between $350 and $1,450 depending on what failed, and most small-to-mid repairs are done the same week we inspect. That number is not a guess. It is a written price you get before any work starts, and it does not move at the door. Our crews work in Lemon Heights, Cowan Heights, and the hillside lots along Newport Boulevard and Foothill Boulevard, where original cedar shake and low-slope roofs from the 1950s through 1980s fail in very specific ways. Call (559) 258-5703 and a live person answers. Always.
North Tustin is not a generic Orange County suburb. The housing stock here skews older, larger, and more custom than what you find across the 55 in Tustin or Santa Ana. Ranch-style homes on half-acre lots. Original wood shake. Wide low-slope sections over patios and additions. When those roofs leak, the fix is not always a simple patch. It takes a roofer who knows what a 60-year-old cedar roof in Cowan Heights does after two decades of sun and Santa Ana wind. That is the work we do every week.
Why Brennan Roofing Co Orange County Is North Tustin’s Preferred Roof Repair Company
We operate under something called The Garrison Standard. It is not a slogan. It is a written set of rules our crews follow on every job, in every neighborhood, on every roof. Price goes on paper before work begins. Technicians are background-checked and arrive in uniform. If the repair fails within one year, we come back and fix it at no charge. That is the 365-Day Done Right Promise, in writing, on every repair and installation we do in North Tustin.
Homeowners here have been burned before. A roofer quotes one number on the phone, then finds “additional rot” once the shingles come off, and the price doubles. That does not happen with us. The price you approve is the price you pay. If we find hidden damage during the repair, we stop, show you photos, and put the new number in writing before we proceed. No surprises at the door. No change orders you never approved.
Travis Oakley runs this location and enforces The Garrison Code on every job. Dispatch and scheduling are coordinated from the brand’s Los Angeles office, and our crews serve North Tustin directly. That means when you call to schedule an inspection, you are not routed to a call center. You reach someone who knows which roads run into the hills and which homes still have original shake.
Styles & brands we work with
Flat Roof Repair in North Tustin
Flat roof repair in North Tustin typically runs $450 to $1,100 for a localized patch, and $1,800 to $4,200 if large sections of the membrane need to be cut out and replaced. Many homes here were built with low-slope sections over patios, carports, and family room additions, and those sections fail at the transitions. Water pools where the slope is too shallow, then works its way under the membrane at seams and flashing. In Lemon Heights and Cowan Heights, we routinely find the original built-up or torch-down layers are long past their useful life.
What the job involves: we locate the leak (often nowhere near the water stain on your ceiling), cut back the failed membrane, replace any rotted decking, then patch and seal the area with compatible material. On old low-slope sections, the real problem is often the transition to the steep slope. Improperly lapped underlayment and missing drip edge let Santa Ana-driven rain run backward under shingles. We fix the transition, not just the hole.
Cedar Shake and Low-Slope Transition Failure
On 1950s and 1960s custom builds around Cowan Heights, we see this constantly. The flat roof over the patio meets the pitched shake roof at a valley or wall, and the flashing detail was never done with enough overlap. Moisture gets behind it, rots the decking, and leaks into the living space below. Repairing just the membrane without fixing the transition means you will call us again next winter. We fix both in one visit.
Santa Ana Wind Uplift on Flat Sections
When Santa Ana winds gust through the canyon foothills, they create negative pressure that lifts poorly fastened membranes and edge metal. If the drip edge is missing or the last row of fasteners is too far back from the edge, the wind gets under the membrane and peels it. North Tustin’s exposed hillside lots are particularly bad for this. We re-secure the perimeter and replace edge metal where it has pulled away.
Shingle Roof Repair in North Tustin
Shingle roof repair in North Tustin generally costs $350 to $900 for a standard repair (a handful of torn, cracked, or missing shingles), and up to $1,450 when underlayment, decking, or flashing replacement is involved. The age of your roof matters more than the size of the visible damage. North Tustin has a high concentration of original roofs from the 1960s and 1970s, and shingles on those roofs are often so sun-brittle that even walking on them can cause new cracks.
What it involves: we match your existing shingle as closely as possible, remove the damaged section without disturbing the surrounding shingles, inspect the underlayment beneath, and nail the replacement to the manufacturer’s pattern. On architectural shingle re-roofs where the nailing pattern was sloppy, whole starter strips can lift along the eaves during Santa Ana gusts. We repair the fastening, not just the visible shingle.
Cedar Shake Replacement in the Hills
In Lemon Heights especially, we never recommend generic patching on an original cedar shake roof. Sun-baked shakes there split and curl. Walking them for an inspection can crack six more while you are looking for the one that leaked. The right fix is replacing the damaged shakes with new cedar and installing ice and water shield along the valleys. That is a different skill set than nailing down an architectural shingle, and the repair lasts instead of failing the next winter.
Architectural Shingle Fastening Failures
North Tustin’s exposed hillside properties get hit harder by Santa Ana winds than the flatlands of Orange or Costa Mesa. When a re-roof was nailed wrong, the starter course is the first thing to go. We see it along the eaves. The whole strip lifts, and once it goes, water gets under the first course of shingles. Fixing it properly means reseating the starter strip with a correct nail pattern, not adding roofing cement and hoping.
For this kind of work and everything else under it, our Roof Repair team handles shingle replacement, leak repair, flashing repair, flat roof patches, vent boot repair, and valley repair across North Tustin.
Trusted Brands We Service in North Tustin
We install and repair roofs using materials from GAF, CertainTeed, and Tamko, among others. When a North Tustin homeowner needs a repair on an existing CertainTeed architectural shingle roof, we can source the matching shingle locally. When a cedar shake repair requires new shakes in Lemon Heights, we order true cedar, not a fiber-cement imitation, unless the homeowner asks for that option. We stock common flashing, drip edge, vent boots, and fasteners, so most repairs do not wait on parts. You get plain options explained plainly: what each material costs, what it lasts, and whether it makes sense for a home on an exposed hillside lot versus a shaded street in Cowan Heights.
Common Roof Repair Problems We See in North Tustin Homes
- Sun-brittle cedar shake in Lemon Heights and Cowan Heights. Original shake roofs from the 1950s through 1980s are so dry that shakes split when walked on. Leaks show up every winter rain and get worse each year.
- Low-slope transition failures on 1960s custom homes. Sections over patios and additions fail where the flat roof meets the pitched roof. Improperly lapped underlayment and missing drip edge let wind-driven rain run backward under shingles.
- Poorly fastened architectural shingles on re-roofs. When nailing patterns are not followed, starter strips lift along the eaves during Santa Ana winds. Exposed hillside lots get the worst of it.
- Flashing failures at chimneys and valleys. Original flashing on 50- to 70-year-old roofs has corroded or pulled away. Water gets behind it and travels far from the visible gap before dripping onto your ceiling.

FAQs About Roof Repair in North Tustin
Because the underlying problem is not just the visible crack or missing shake. The shakes are sun-brittle, the felt underneath is shot, and water is entering at the valleys and flashing, not only where you see the gap. A patch fixes one symptom. The roof keeps leaking because the valley underlayment and flashing were never replaced. In Lemon Heights and Cowan Heights, where original shake is dense, the only lasting fix usually involves replacing the damaged shakes and installing ice and water shield along the valleys. Call (559) 258-5703 to have us inspect it properly.
You need someone who has seen how these 1950s and 1960s low-slope additions fail. The transition from flat to steep is where the damage happens, and a roofer who mostly works newer tract homes will miss it. That is not a knock on other roofers. It is a fact about how these specific roofs are built. Our crews work those transitions regularly across North Tustin.
In two ways. First, the wind finds shingles that were nailed too high or with too few nails and lifts them, leaving bare spots. Second, on exposed hillside lots, the wind drives rain sideways under shingles and flashing. A repair done without accounting for wind-driven rain will fail in the next Santa Ana event. We fasten to manufacturer spec and check the starter strip and edge metal, not just the visible damage. Call (559) 258-5703 for a free estimate on any wind-related repair.
A square is 100 square feet of roofing. A bundle is one wrapped package of shingles. Three bundles typically cover one square, depending on the shingle. Some quotes list shingles by the square, others by the bundle. When you are comparing numbers, make sure both quotes are priced the same way. Our written estimates in North Tustin state exactly how many squares or bundles we are replacing, so you can hold the number against any other quote.
Because months of heat and UV dry out the roofing material and shrink it. Wood shake splits. Membrane seams pull apart. Flashing expands and contracts until the sealant fails. By the time the first winter rain arrives, the roof has multiple entry points that were not there in spring. That is why a pre-winter inspection in North Tustin catches leaks before they show up on your ceiling. We offer free inspections for homeowners who suspect they have this problem.
