Fast, Reliable Roof Repair Across Sherman Oaks
Roof repair in Sherman Oaks usually runs between $350 and $950 for most pitched-roof fixes, and $500 to $1,400 when the work involves re-coating or re-detailing a flat or low-slope section. We get calls from the 91403, 91423, and 91413 ZIP codes every week, and most are about sun-cooked membranes and pulled flashings rather than wind-torn shingles. Our Roof Repair crews know the Valley’s heat cycle and what it does to older ranch homes, and we quote honestly before touching anything. If you’re seeing stains on a ceiling or cracked coating on a garage roof, call (866) 321-6172 and we’ll schedule an inspection.
Why Van Nuys Roofing Co Is Sherman Oaks’s Preferred Roof Repair Company
Sherman Oaks homeowners keep our number because we don’t steer them toward a brand we happen to stock. We work with GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, which means the recommendation you get is based on what your roof actually needs and what your budget can handle. Not on supplier kickbacks. That matters when you own a 1950s ranch with architectural shingles on the pitched section and a deteriorating modified-bitumen flat over the garage addition. One roof, two completely different failure modes. Most crews are only really fluent in one of those.
Rick Dominguez runs our crews, and he’s walked hundreds of Sherman Oaks roofs from Magnolia Boulevard up into the hills above Ventura. The common thread: UV damage and thermal cycling, not rain. That’s why we start every repair with an inspection, whether you hire us for the fix or not. You get a straight condition assessment first. Repair or replace, we’ll tell you which one actually makes sense.
Styles & brands we work with
Metal Roof Repair in Sherman Oaks
Metal Roof Repair in Sherman Oaks is mostly about seam and fastener work on standing-seam panels over the mid-century moderns and rebuilt hillside homes south of the Boulevard, plus the metal patio covers and outbuildings on the acreage lots. Metal doesn’t rot, but it moves. Long 95°F summers expand panels and fasteners loosen, gaskets flatten, and water finds the seam. The metal itself is fine. The connections aren’t. A loose fastener left alone becomes a drip that looks like it’s coming from the ridge when it’s actually eight feet down the panel.
Typical metal roof repair runs $450 to $1,300 depending on how many seams need re-tooling and whether we’re re-packing fasteners or replacing panel sections. We inspect the seam profile, the fastener gasket condition, and the transition flashing at walls and curbs before we quote.
Standing-Seam Fastener and Gasket Service
On long panel runs, the real leak source is rarely visible from the ground. We work seam by seam, checking fastener torque and gasket compression. Sherman Oaks afternoon heat hardens rubber gaskets faster than coastal air does, which is why we replace them rather than just snug the fasteners and hope.
Metal Roof Flashing and Transition Repair
Where a metal roof meets a stucco chimney or a wall, the transition flashing takes the full thermal movement. We pull the old counter-flashing, re-detail the transition, and re-seat the panel edge. This is the fix that actually stops the leak instead of chasing it with caulk.
Commercial Roof Repair in Sherman Oaks
Commercial Roof Repair in Sherman Oaks mostly happens on the 1960s and 70s apartment buildings and storefronts along Van Nuys Boulevard, Ventura Boulevard, and the side streets between them. These buildings carry built-up and rolled roofing, old wood-deck flat sections, and years of previous coatings that may or may not be compatible. When a tenant reports a ceiling stain, the actual membrane failure is often twenty feet from the stain because water travels between the roof deck and the insulation before it finds a seam in the drywall below.
Commercial repair scopes run $800 to $2,800 for targeted membrane and flashing work, and more when we’re re-coating a full low-slope section. We scope the roof in person, map the wet insulation with a moisture meter, and give you a line-item quote that separates membrane work from flashing work from coating work. No mystery bundles.
Low-Slope Membrane and Coating Repair
The built-up roofs on Sherman Oaks apartment buildings fail at seams and scuppers first. We cut back the alligatored membrane, patch the base layer, re-seat the flashing at drains and parapets, and then coat the section to match what’s still holding. The patch without the coating is a temporary fix.
Parapet Wall and Scupper Flashing
Parapet walls bake all day in the Valley sun, and the flashing at the parapet-to-roof junction pulls loose as the wall and deck expand at different rates. We re-detail those junctions properly, which is the difference between a repair that lasts ten years and one that leaks again next winter.
Trusted Brands We Service in Sherman Oaks
Seven leading brands, one crew that knows them all. Sherman Oaks homeowners ask us to work on GAF Timberline shingles, CertainTeed Landmark, and Owens Corning Duration on the pitched sections, plus IKO and Tamko products on the flatter sections. Because we install and repair across all seven lines, we know the installation tolerances, fastener patterns, and warranty requirements for each. Your roof, your material choice. We keep common flashing profiles, vent boots, and coating systems on the trucks, so a Sherman Oaks repair doesn’t wait on a week of parts ordering.
Common Roof Repair Problems We See in Sherman Oaks Homes
- Alligatored flat-roof coatings. The modified-bitumen and elastomeric coatings on garage additions and low-slope sections cook in the Valley sun until they crack in a pattern that looks like alligator skin. The leak usually shows up inside far from the actual membrane failure, which is why a visual inspection from the ground tells you almost nothing.
- Wall and penetration flashing pull-out. The decking and coating on low-slope roofs expand and contract through long 90°F+ summers. Flashing at the wall junction and around pipes and vents pulls loose from that movement. The first hard winter rain finds it.
- Brittle drip edge and dried underlayment. Older ranch roofs in the 91403 and 91423 flats often have intact-looking shingles hiding dried-out felt and cracked drip edge along the eave. These fail silently until water shows up at the fascia board or inside the wall.
- Heat-damaged metal seams on patio covers and outbuildings. Standing-seam metal on accessory structures heats and cools hard in the Sherman Oaks sun, loosening fasteners and flattening gaskets. The panels are fine, but the seam integrity is gone.

AfterPricing for Roof Repair in Sherman Oaks, CA
Shingle replacement on a pitched Sherman Oaks roof runs $400 to $900 for a typical repair section. Flashing repair is $350 to $800. Flat roof patches and re-coating work run $500 to $1,400 depending on square footage and coating system. Vent boot replacement is $200 to $450. Valley repair sits between $400 and $900. The spread exists because a 1940s ranch with a single flat garage section is a different job than a hillside lot with a long material haul, an outbuilding, and no staging room. We give written line-item quotes after an on-site inspection, and the estimate is free. Call (866) 321-6172 to schedule one.

FAQs About Roof Repair in Sherman Oaks
The coating keeps cracking because the membrane underneath is still moving. Sherman Oaks afternoon roof-surface temperatures routinely exceed 140°F on flat sections, and the decking expands and contracts every single day. If we re-coat without first cutting out the alligatored base membrane and re-detailing the wall flashings, the new coating inherits the same failure points. The fix is section removal, flashing re-work, and then a compatible coating system, not another layer on top of the cracked one. Call (866) 321-6172 and we’ll tell you what’s actually under the coating before you spend another dollar on it.
It depends on the scope and which jurisdiction governs your property. A like-for-like repair on an existing roof, shingle section replacement, or flat-roof patch generally won’t require a permit in the City of Los Angeles. But if the work is on a detached ADU, a converted garage, or an outbuilding that was permitted under county rules, or if the repair involves structural decking replacement, you may be in Los Angeles County permitting territory and a permit could be required. We check that before we quote and we’ll tell you plainly what applies. Call (866) 321-6172 and we’ll sort out the jurisdiction question for your specific lot.
We walk the property before we quote anything. On Sherman Oaks hillside and acreage lots, that means checking where the material can be staged, how far the crew carries rolls and bundles, and whether a ladder can be safely set on the slope. Haul distance and staging change labor time, which changes the quote. We factor it in up front so the number we give you is the number on the invoice. Call (866) 321-6172 and we’ll come scope the access and drainage on your lot as part of the free estimate.
We inspect both sections independently, because they fail independently. On the pitched section we’re looking for cracked shingles, granular loss, brittle drip edge, and lifted flashing at valleys and walls. On the flat section we’re looking for alligatoring, seam separation, and pulled flashing at the wall junction. On a ranch home off Magnolia Boulevard, we often fix the flat section and leave the shingles alone because the shingles still have years left. We’ll tell you which section is actually failing and leave the rest alone. Call (866) 321-6172 for an inspection that separates the flat work from the shingle work.
Yes, in two ways. First, roof runoff has to go somewhere, and if your lot is graded toward the foundation or the drainage swales are clogged, water backs up against the fascia and finds its way into the roof assembly at the eave. Second, on open Sherman Oaks lots with outbuildings and detached structures, we have to account for where the downspouts discharge and whether a clogged drain line is the real source of what looks like a roof leak. We check grading and drainage as part of our inspection because a roof repair that ignores the runoff path fixes only half the problem. Call (866) 321-6172 to have us look at the roof and the lot together.
