Fast, Reliable Roof Inspection Across Montclair
A roof inspection in Montclair typically costs $190 – $390 for most single-family homes, and our crews are on roofs across the city within a few days of your call. If you own a 1950s – 1970s ranch or tract home in Montclair, your roof has been baking under Inland Empire sun for decades, and the underlayment under those shingles may already be failing. We inspect the whole system, not just the surface: shingles, underlayment, decking, flashing, drip edge, and the drainage that carries water away from your foundation. Call (341) 208-3988 to schedule yours. The phone is answered by a live person, any hour.
Why Brennan Roofing Co Riverside Is Montclair’s Preferred Roof Inspection Company
We inspect roofs in Montclair the way a roofer inspects a roof: by walking every slope, lifting shingles where they meet flashing, and looking at what’s underneath, not just what’s on top. Homeowners in Montclair call us because the inspection report they get is written in plain English, includes the dollar ranges for anything we find, and comes with a written price before any repair work starts. Our Roof Inspection team works from a defined standard, The Garrison Standard, and it does not change from job to job. Travis Oakley leads our crews, and every technician who steps onto your Montclair roof is background-checked and in uniform.
We know the housing stock here. Original composition shingle roofs on 1970s northside Montclair tracts are not the same as newer builds in Rancho Cucamonga or Upland. Brittle shingles, dusted underlayment, failed eave flashing: these are the things we look for first on older Montclair homes. And when something is wrong, we tell you exactly what it costs to fix, in writing, before any work begins. That’s how we operate in every neighborhood we serve across Montclair, from the tract streets east of Central Avenue up toward the I-10.
Styles & brands we work with
Commercial Roof Inspection in Montclair
Commercial Roof Inspection in Montclair covers flat and low-slope roofs on shops, offices, and industrial buildings along Holt Boulevard and the corridors near Montclair Place, as well as outbuildings on the city’s larger acreage parcels. A commercial inspection in Montclair runs $450 – $1,200 depending on roof size, access, and how many penetrations the building has. We check membrane seams, parapet flashing, scuppers, and any equipment curbs where water pools or wind pulls seams apart.
Built-Up and Modified Bitumen Roofs
Older commercial buildings in Montclair often have built-up roofs with gravel surfacing or modified bitumen membranes that crack at seams after decades of heat. We look for blisters, alligatoring, and any area where the surfacing has worn thin enough to expose the membrane to UV.
Metal and Standing Seam Roofs
Warehouses and shops along the industrial corridors east of Central Avenue frequently use metal roofing. We check fastener gaskets, panel laps, and ridge caps for wind-driven water entry, then match any repair to the existing panel profile so it does not look patched.
Roof Inspection Services in Montclair
Roof Inspection Services in Montclair start with a walkover of every accessible slope, then move to the details: pipe boots, valley metal, chimney step flashing, and the drip edge at every eave. A standard residential inspection in Montclair costs $190 – $390. We inspect the decking and underlayment by lifting shingles at the roof-to-wall and roof-to-valley intersections, because that’s where rot hides on 1950s – 1970s tract homes.
Acreage and Detached Structure Scoping
Montclair lies within San Bernardino County, and detached workshops, studios, and ADUs on larger parcels often fall under county roof permit review. We scope their roofs separately during the inspection and note any setback issue where a structure sits too close to a septic tank or well. That changes the repair path, and we include it in the written quote instead of discovering it after work starts.
Grading and Drainage Review
Every inspection we do in Montclair includes a look at how the roof drains into the lot. On open land, a roof replacement that ignores slope and gutter fall can send runoff toward a septic drain field or well head. We measure the roof’s drainage discharge points against the lot’s grade and flag regrading or re-sloping when it’s needed.

AfterCommon Roof Inspection Problems We See in Montclair Homes
- Dusted underlayment on 1950s – 1970s composition roofs. The felt under shingles on older Montclair tract homes breaks down into powder after forty or fifty years of heat. When shingles are lifted, the underlayment crumbles to the touch, which means any shingle failure becomes a direct leak into the decking.
- Dry-rotted decking at roof-to-wall intersections. Cheap overlay reroofs from previous owners often skipped lifting shingles at the eave flashing. Water wicked in over decades, rotted the plywood edge, and left a hidden failure that a surface-only inspection misses. We lift shingles there specifically.
- Outbuilding roofs skipped entirely. Detached workshops, studios, and old garage roofs on Montclair acreage parcels rarely get inspected during a main-house roof check. Their composition shingles fail unnoticed until a Santa Ana wind storm lifts whole sections.
- Santa Ana wind damage at south and east eaves. Gusts from the Cajon Pass hit Montclair from the northeast, driving rain sideways under old drip edges. We inspect the east and northeast eave lines carefully on every Montclair roof, because that’s where wind-driven water does the most damage.

FAQs About Roof Inspection in Montclair
An acreage inspection in Montclair includes scoping the roof’s drainage discharge against your septic tank and well setbacks, plus inspecting outbuildings that a standard tract inspection skips. That adds $100 – $200 to the inspection cost in most cases. Call (341) 208-3988 and we’ll walk the whole site before quoting, not just the house roof.
Yes, and we recommend it. Detached structures on San Bernardino County parcels often need their own permit path for roof work, and their roofs fail faster because they are rarely maintained. We inspect them as part of the site scope for an additional $75 – $150. If the structure sits within a septic setback, we flag that in the report so the repair quote includes the right permit approach.
We look first at the east and northeast eaves, where Santa Ana gusts drive rain sideways under old drip edges and into roof-to-wall intersections. In Montclair, that’s the standard failure start point on 1950s – 1970s tract homes. A surface-level inspection that skips lifting shingles there will miss rot that leaks into the wall months after a reroof.
Yes. We lift shingles at roof-to-valley and roof-to-wall intersections and at any visible fungal streaking or granule loss. On older Montclair homes this is where dry-rotted decking and dusted underlayment hide. The inspection report notes what we found and what it costs to fix, in writing.
Open lots sloped toward a septic drain field or well head can make a roof replacement worse than useless if the runoff path is not fixed at the same time. We inspect the lot grade against each downspout and scupper discharge before quoting, and we add regrading or gutter re-sloping to the written scope when needed. The goal is water away from the house, not toward it.
