Why Brennan Roofing Is Altadena’s Preferred Roof Inspection Company
Altadena homeowners hire us because we speak the local trade fluently. We know the difference between a 1923 Craftsman bungalow off Mariposa Street and a mid-century ranch near Lake Avenue. We know that west-facing slopes at the base of the San Gabriels take wind scouring that east-facing slopes never see. That local knowledge changes what we look for and how we price it.
Brennan Roofing operates under The Garrison Standard, and that means something specific. Every technician who arrives at your Altadena home is background-checked and in uniform. You know who is on your roof. The price goes on paper before any work starts, and it does not move at the door. If we miss something and it fails within a year, the 365-Day Done Right Promise means we come back and fix it at no charge. In writing, for one full year.
Our Roof Inspection crews are dispatched from our Los Angeles office and serve Altadena locally. We are part of the Garrison Partners family, founded in 2000, and each location is independently owned and operated to the same standard. Travis Oakley leads our team, and he holds every inspection to the same bar: probe it, document it, price it honestly.
Hail Damage Roof in Altadena
Hail Damage Roof assessments in Altadena are less common than wind and heat damage, but when a hailstorm does roll off the San Gabriels, it hits steep historic slopes hard and leaves damage that is easy to miss from the ground. What we look for: bruised shingles, cracked cedar shakes, dented flashing, and granule loss that signals the protective surface is failing. On a 1920s Craftsman with original wood shakes, hail often shatters edges that were already micro-cracked from years of Santa Ana wind.
What a hail inspection actually involves
We walk the entire roof, not just the street-facing slope. We probe suspect shakes and shingles, check valleys and penetrations, and document everything with photos tied to a written report. If we find hail damage, we price the repair or replacement on the spot, in writing, before any work starts.
What hail damage costs to fix in Altadena
A localized hail repair on an asphalt roof in Altadena typically runs $400 – $900. If hail has damaged cedar shakes or underlayment on a steep historic roof, the number climbs toward $1,500 – $3,000 depending on slope access and decking condition. We never start work until you have approved that number on paper.
Roof Estimate in Altadena
A Roof Estimate in Altadena is where most roofers lose homeowners. They quote a number, start the job, and then “discover” problems that double the bill. We do it differently. Our estimates are built from a physical inspection plus local knowledge of how Altadena homes fail, so the number on paper reflects what we actually expect to find. For a standard asphalt roof replacement on a typical Altadena home, expect $14,000 – $22,000. For a steep historic home requiring full tear-off with Class A fire-rated materials, $28,000 – $45,000 is realistic.
Allowances for what we cannot see
On older Altadena homes, the decking underneath is often undersized or rotted at penetrations. We write allowances into the contract for this, so if we open the roof and find bad decking, the repair cost is already agreed upon. No surprise change orders. No pressure at the ladder.
Compare our bid to any other
Bring us any competitor estimate and we will walk through it line by line. We do not compete on being the cheapest. We compete on the number being real, the materials being named, and the crew showing up on time, in uniform, background-checked.
Trusted Brands We Service in Altadena
We install and service materials from GAF, CertainTeed, and Owens Corning, among other manufacturer lines. For Altadena homeowners, that matters because local supply houses stock these brands consistently, which means faster turnaround when we need materials for a repair or replacement. We explain the differences between brands plainly: what holds up better under UV at elevation, what carries a better wind rating, and what makes sense for a home in a wildfire-prone area. You choose with the facts in front of you.
Common Roof Inspection Problems We See in Altadena Homes
Roofs in Altadena fail in predictable ways, and a ground-level look misses most of them. Here is what our inspections most often turn up:
- Wind-scoured cedar shakes on west-facing slopes. The Santa Anas hit those slopes harder than anywhere else in the foothill corridor. Shakes crack and lift at the edges, letting water in years before a leak shows inside.
- Heat-damaged underlayment after the Eaton Fire. Even roofs that look intact from the street often have underlayment that got brittle and cracked from fire heat exposure. Patching over it just delays a bigger failure.
- Undersized original 1920s decking. Craftsman and Spanish Revival homes of that era often used thinner decking than modern code requires. Add decades of heat and dry cycles, and it rots at chimney penetrations and ridge vents long before the field of the roof shows problems.
- Failed flashing and drip edge on steep historic roofs. Altadena gets little rain, so when it does come, old flashing at chimneys and soffits lets water in quietly. The leak shows up a floor below, months after the storm.
Pricing for Roof Inspection in Altadena, CA
Inspection pricing in Altadena breaks down like this: a standard walk-and-probe inspection on a single-story home runs $250 – $350. A two-story or steep historic home runs $350 – $500 because it takes longer and requires more safety rigging. If you need drone imaging of a complex roofline or post-Eaton Fire underlayment sampling, add $100 – $200. Every inspection includes a written report with photos and line-item pricing for anything we find. The inspection fee is credited back if you hire us for the repair or replacement. Call (361) 320-9467 for a free estimate on the inspection itself, and we will put the exact number in writing.

FAQs About Roof Inspection in Altadena
Yes, because on a west-facing slope, what looks fine from the ground often is not fine once we probe it. We lift shaken edges, check valleys, and sample underlayment at penetrations. If we find micro-cracks from wind scouring or heat-brittled underlayment from the Eaton Fire, we document it with photos and price it before any work starts. Call (361) 320-9467 to schedule an inspection that actually looks.
We write allowances into the contract before we start. If we open the roof and find rotted decking, undersized framing, or failed waterproofing that was not visible from the surface, the allowance covers it at an agreed price. You approve the additional work in writing before we touch it. Nothing gets sprung mid-job, and the price does not move at the door. That is the Garrison Standard.
If we are doing a full replacement on a home of that age, yes, the permit process will likely require bringing the roof assembly up to current code. That can mean new decking thickness, improved ventilation, and Class A fire-rated materials. We pull permits, we pass inspections, and we factor those upgrades into the estimate from the start, so there is no surprise line item later. Call (361) 320-9467 for an exact quote on your home.
In some cases, yes. If the damage is localized and the surrounding underlayment is sound, a patch may be enough. But after the Eaton Fire, we have seen many roofs where underlayment was heat-damaged well beyond the visible burn area. Patching over that just means another failure in a year or two. Our inspection determines whether a patch is honest or a band-aid, and we will tell you plainly which one it is.
We quote it line by line: tear-off, decking allowance, underlayment, ice and water shield, flashing, drip edge, material cost by brand, and labor. Every line has a dollar amount attached. You can hold our estimate next to any competitor’s and see exactly what is included and what is not. Most Altadena homeowners tell us it is the first estimate they have received that actually makes sense on paper.
