Roofers in Montclair, CA
Roof inspection in Montclair usually starts with a specific call: a homeowner found water staining on a hallway ceiling after a Santa Ana wind event, or a patio cover seam has been dripping for weeks and they want to know if the main roof is next. Gable Roof Repair has served Montclair since 2016, and most of what we find on the city’s 1950s and 60s ranch homes comes down to three things: shingles that gave up years ago, flashing that was never detailed correctly at the roof-to-wall junctions, and flat-section patio covers where the rolled roofing has baked through. We inspect first, recommend second. Call (866) 650-8319 when you’re ready for an honest read on what your roof actually needs.
Why Montclair Homes Are Different
Montclair sits in the Pomona Valley at the foot of the San Gabriel Mountains, and the roofs here don’t fail the way they do in coastal towns or mountain communities. There’s no snow load, and rain is seasonal. What Montclair gets instead is relentless inland heat and wind-driven dust channeled down from the canyons. Roof-deck temperatures on a July afternoon in the 91763 zip code push well past 140 degrees, which accelerates shingle aging and stresses every flashing joint and vent boot on the roof. Thermal cycling – the daily expansion and contraction from hot days to cool nights – is what eventually separates flashing from walls and breaks the seal strips on composition shingles.
The housing stock makes it worse. Montclair is dominated by post-WWII single-story ranch and tract homes, most built between 1950 and 1975. A large share of these roofs are on original or second-generation shingles that are well past their design life. On the older ranch tracts especially, the low-slope rear patio covers and flat-section additions from the 60s and 70s are where leaks show up first. Hot-mop or rolled roofing on those sections fails long before the main shingle field does, and by the time water reaches the interior ceiling, the substrate underneath is usually soft. Dry rot at the roof-to-wall junctions on these 1950s-era homes is a pattern we see weekly, not occasionally.
Styles & brands we work with






Our Main Montclair Services
Most Montclair homeowners reach us for one of two reasons: something is leaking and they want it fixed without a full-roof pitch, or the roof is clearly at the end of its life and they want a straight answer on replacement. Both start with the roof itself, not a sales script.
Roof Repair in Montclair
Montclair roof repair typically means chasing a leak at a pipe boot, a valley, or a roof-to-wall flashing on the back side of the house where canyon winds have worked a corner loose. We match the repair to the existing shingle brand and profile where possible, which matters on the mid-century tracts where the roof lines are visible from the street. One condition we see constantly in Montclair is cracked and separated flashing at the low-slope patio cover junctions, which lets water into the framing long before anyone notices. We repair when it makes sense, replace when it’s right. Full details are on our Roof Repair in Montclair page.

Roof Replacement in Montclair
A full replacement in Montclair is a bigger decision, and it’s usually driven by age. When the shingles on a 1960s ranch have lost their granule layer and the sheathing is soft at the edges, patching buys time but not much. We walk the roof with you, show you what we’re seeing, and quote the job at the material tier you choose – from value lines to premium shingles from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. The roof’s job is to protect everything underneath it, and a replacement has to be done as a system: deck, underlayment, flashing, shingles, ventilation. Read more about how we approach it on our Roof Replacement in Montclair page.

Roof Inspection in Montclair
Roof inspection in Montclair is most valuable on the 1950s-to-70s ranch and tract homes where the original sheathing, fascia, and flashing are all aging at once. The inland heat here bakes composition shingles until they’re brittle, and the flat patio cover sections from the 60s and 70s fail years before the main shingle field does. An inspection separates what’s actually wrong from what can wait. That’s the whole point of our standalone Roof Inspection service – the diagnosis isn’t tied to a replacement quote, so you get a straight answer about the roof you have.
Roof Inspection Services
Signs you need it
Curling or missing shingles, granule buildup in gutters, water stains on ceilings or at wall junctions, and daylight visible through the attic sheathing are the most common calls we get from Montclair homeowners.
What it costs in Montclair
A standard single-family roof inspection in Montclair runs $150 to $350 depending on roof size, pitch, and the number of flat sections that need attention.
How we do it
We walk every slope, check flashing points and vent boots, assess the patio cover membrane, and document findings with photos before giving you a written summary of what needs work now and what can wait.
Hail Damage Roof
Signs you need it
Hail in the Pomona Valley is sporadic but does occur, and it leaves circular bruise marks on shingles where granules have been knocked off, along with dents on soft-metal vents and flashing.
What it costs in Montclair
A hail-specific assessment in Montclair is part of a full inspection, which runs $150 to $350, and includes a documented report you can use if an insurance claim is warranted.
How we do it
We inspect the roof for hail impact patterns, test the shingles for granule loss and bruising, check soft metals for denting, and photograph the evidence for your records or insurer.
What Roof Inspection Costs in Montclair
| Item | Typical range in Montclair |
|---|---|
| Standard roof inspection (single-family ranch/tract home) | $150 – $350 |
| Inspection with written photo report | $200 – $400 |
| Inspection including flat patio cover / rolled roofing assessment | $200 – $450 |
Prices vary with roof size, pitch, and how many separate flat sections or additions the home carries. Every inspection quote is given before we start, and the price doesn’t change once we’re on the roof.
Do I need a roof inspection before selling a home in Montclair?
Most Montclair home sales move faster when the roof’s condition is documented in writing, and a $150 to $350 inspection can prevent a last-minute negotiation reset. Buyers here ask about the patio cover membrane specifically, since those fail before the main shingle field does. Call (866) 650-8319 to schedule one before listing.
What does a Montclair roof inspection check that a general home inspection misses?
General home inspections look at the roof from the ground or a ladder edge. We walk the entire surface, check the flat patio cover seams, verify flashing at every wall junction, and assess the attic ventilation from inside. That’s where the mid-century ranch homes in Montclair hide their real problems. Call (866) 650-8319 to book an inspection.
Brands We Service in Montclair
We work with roofs from seven major shingle brands, which matters in Montclair because the mid-century tract homes carry everything from original wood shake conversions to modern architectural laminates. We routinely match and repair shingles from GAF, CertainTeed, and Tamko, with additional product lines from Owens Corning, IKO, Atlas, and Boral available for replacements. Parts for common profiles are stocked locally, so a repair isn’t held up waiting on a distributor. See the full material range on our brands page.

What Montclair Customers Say
"Quality work on the repair. There were a few nails left in the driveway that the magnet missed, so check yours before driving over it. Otherwise no complaints."
— Eduardo Torres"Added a ridge vent and cleared the blocked soffit vents. Attic temperature in the summer dropped noticeably and the upstairs is livable now."
— Kevin Wong"Roof is solid and the price was competitive. The job ran a day over because of weather, which is nobody's fault, but I would have liked a call about it rather than noticing the crew hadn't shown up."
— Beatriz Guzman
