Fast, Reliable Roof Repair Across Montclair
Roof repair in Montclair typically runs $350 – $950 for targeted fixes like flashing, vent boots, and shingle patches, while a full sheathing replacement on an older tract home can range from $4,500 – $9,800 depending on square footage and decking condition. Most repairs on the city’s 1950s – 1970s single-story homes wrap up in a single day once materials are on site. That last part matters here more than in coastal cities: Montclair’s position along the 10 freeway in the Inland Empire thermal belt means our crews plan material runs for 100°F-plus surface temperatures, not just rain.

Why Hollywood Roofing Co Is Montclair’s Preferred Roof Repair Company
We’ve repaired enough roofs across the 91763 zip code to know what Montclair throws at a shingle. The work profile here is different from the steeper, older housing in LA or the foothill cities. Homes off Monte Vista Avenue, around the Montclair Plaza area, and throughout the tight post-war tracts east of Central Avenue are overwhelmingly low-slope, single-story, stucco ranch designs with original wood sheathing. That changes how we scope every job before quoting.
Roland Vega, our owner, has built Hollywood Roofing Co around a simple rule: know exactly what your roof needs, nothing more. That’s why we offer a standalone Roof Repair assessment that isn’t a sales funnel disguised as a free estimate. You get an honest condition report. You decide what gets fixed and when. For Montclair homeowners, that means no pressure to replace a roof when a valley repair or flashing fix is all that’s actually failing.
Styles & brands we work with






Metal Roof Repair in Montclair
Metal Roof Repair in Montclair usually addresses detached garages, patio covers, and outbuildings rather than the main home, since most of the city’s original tract houses were built with asphalt shingles. A metal panel replacement or fastener re-tighten on a detached structure typically runs $400 – $1,200 depending on panel length and whether purlins need reinforcement. On a 1950s ranch off Monte Vista Avenue, our crew repaired a detached garage roof with metal panels after Santa Ana winds loosened the fasteners, then replaced the main roof’s shallow-pitch decking with GAF architectural shingles.
Loose Fasteners and Wind Damage
Santa Ana events rattle metal roofs on Montclair outbuildings more than homeowners expect. The issue is rarely the panel itself. It’s the fastener pull-out from decades of thermal cycling. We inspect the full fastener pattern, not just the visibly lifted area, because one loose section usually means the whole roof has lost tension.
Panel Replacement on Low-Slope Covers
Patio covers and flat metal sections over additions collect heat and ponding. When we replace panels on these, we check the underlayment and pitch first. A panel swap on a patio cover in Montclair is usually $350 – $650, assuming the frame is sound.
Commercial Roof Repair in Montclair
Commercial Roof Repair in Montclair is concentrated on the retail and warehouse buildings along the 10 corridor and the industrial stretches near the Montclair Transit Center. Flat and low-slope commercial roofs here fail in predictable ways: membrane splits from thermal expansion, ponding at scupper locations, and failed sealant around rooftop units. A targeted commercial patch runs $600 – $1,800, while re-coating a full retail roof typically falls between $3.50 and $6.00 per square foot installed.
Ponding and Membrane Failures
Montclair’s summer heat softens single-ply membranes enough that standing water after winter rains accelerates seam failure. We map ponding areas with a simple water test and identify the low spots before quoting. Fixing the leak without addressing the ponding just means the same repair repeats next season.
Rooftop Unit Re-Sealing
Most commercial leak calls in Montclair ending up being failed HVAC curbs or exhaust vent flashings, not roof-wide failures. We re-seal penetration curbs with compatible sealants and, where needed, install new pitch pans. It’s a smaller job than a full roof, and it’s one we quote honestly rather than upselling into a replacement.
Trusted Brands We Service in Montclair
We’re authorized installers across seven major roofing brands, including CertainTeed, Owens Corning, IKO, and Atlas. That matters in Montclair because no single shingle line handles the thermal belt heat equally well at every price point. We stock common parts for all of these brands locally, which means a repair on a CertainTeed roof doesn’t wait for an out-of-town order. The recommendation is matched to your home and your budget, not to whichever supplier inventory needs moving that month.

AfterCommon Roof Repair Problems We See in Montclair Homes
- Cupped 1x sheathing on shallow-pitch roofs. Decade after decade of 150°F summer roof-surface heat dries and curls the original wood decking. A shingle patch turns into sheathing replacement the moment we strip the old layer and see what’s underneath.
- Aged flashing around low-slope patio additions. Those flat rolled-roof sections over back patios and sunrooms collect water during Montclair’s intense winter rains. The leaks almost always trace back to failed flashing at the transition point.
- Dry-rot fascia and soffit from UV exposure. Original wood trim on 60-year-old tract homes is often soft inside the paint. We find it when we pull drip edge loose, and it changes the repair scope right there on the ladder.
- Granule loss and thermal cracking on south-facing slopes. Montclair’s inland sun blasts asphalt shingles harder than coastal zones. Cracked shingles on south and west exposures are the single most common repair we do in this city.

FAQs About Roof Repair in Montclair
Because the original 1x decking on 1950s – 1970s tract homes has been baking under 150°F summer surface heat for decades, and it cups, splits, and dries out underneath shingles that look fine from the ground. You can’t see it until the shingles are stripped. Once we expose cupped or split decking, code requires replacement before new roofing goes down. We include a sheathing inspection in every Montclair repair quote so you know the real scope before we start. Call (833) 589-7971 and we’ll walk the roof with you.
Montclair’s inland thermal belt bakes shingles at sustained surface temperatures over 150°F, which accelerates granule loss, causes thermal cracking, and dries out the asphalt mat years earlier than in places like Long Beach or Santa Monica. Coastal roofs die from moisture and salt. Montclair roofs die from heat and UV. That means south and west slopes in the 91763 zip code typically need replacement shingles 5 – 8 years earlier than identical products install in Los Angeles coastal zones. We factor this into our repair recommendations so you aren’t patching a roof that’s already structurally tired.
Yes, we do metal roof repair on detached garages, shop buildings, patio covers, and ADUs throughout Montclair. These are often the most neglected roof surfaces on the property. We re-tension fasteners, replace isolated panels, and re-seal seams. Metal outbuilding repairs in Montclair typically run $400 – $1,200. For a specific number on your structure, call (833) 589-7971 and describe what’s leaking or lifting.
Most targeted roof repairs in Montclair, like shingle patches, flashing replacement, and vent boot fixes, fall under standard repair allowances and don’t require a permit. A full re-roof or sheathing replacement does require a building permit through the City of Montclair’s building division. We pull the permits, schedule the inspection, and include the line item in your written quote. If your property sits on acreage in an unincorporated pocket, permitting shifts to San Bernardino County, which can add a few days to scheduling. We scope that before quoting, never after.
We start by identifying the pitch at the transition point and checking whether water ponds or drains. Low-slope rolled-roof sections over patio additions usually fail at the flashing where the flat section ties into the main roof. We cut a test patch to inspect the sheathing underneath. If the decking is cupped or soft, the repair includes a small decking replacement, not just a rolled-roof patch. A patio addition repair in Montclair typically runs $400 – $900, but if the transition flashing has been leaking for years, expect the number to rise once the framing is exposed. Call (833) 589-7971 for a line-item quote on that patio roof.
