Quikrete Roofing: The Los Angeles Owner’s Guide
Quikrete roofing products installed in Los Angeles typically run $470 to $2,125 for repairs and $9,440 to $23,600 for full replacement when handled by a licensed contractor. We stock the common Quikrete repair materials and can usually match what’s already on your roof within one site visit. Most homeowners discover a problem the same way: a brown water stain on the ceiling, granules collecting in the gutter after a rain, or a visible crack in the roof coating after a hot Santa Ana stretch. Here’s what you need to know before you call anyone.
Which Quikrete Models This Applies To
Quikrete makes three main roofing product lines, and each one uses different materials. The most common in Los Angeles is the Quikrete Roof Coat line, a white or gray elastomeric coating usually applied over flat or low-slope roofs common on 1950s and 1960s ranch homes in the Valley. There’s also Quikrete Roof Sealant, a thicker repair compound for patching cracks, seams, and flashing joints, and Quikrete Concrete Roof Tile products for tile roof applications.
Here’s the compatibility gotcha most people miss: Quikrete Roof Coat is formulated for specific substrates. If your roof was originally sealed with an acrylic-based coating, you need an acrylic-compatible product. If it was sealed with a silicone or solvent-based product, applying Quikrete Roof Coat over it without proper prep means the new coating peels within one season. We check the existing coating before recommending anything. That 15-minute material check saves you from a $3,500 mistake.
On the OEM versus aftermarket question: Quikrete doesn’t run its own branded installation network, so there’s no “factory-authorized” installer to chase. What matters is that the product matches your roof’s existing material and the manufacturer’s spec for coverage rate per square foot. We use genuine Quikrete products when the job calls for them, and we’ll tell you if a different material will actually last longer for your specific roof slope and sun exposure.
Penhallow Remodeling is an independent contractor, not affiliated with Quikrete. We work with their products because they’re widely available and consistent, but the warranty on our labor comes from us, not from Quikrete.
Signs Your Quikrete Roofing Is Failing
- Ceiling stains spreading after rain. Water is getting through the roof membrane somewhere, and in Los Angeles it’s often along a seam, around a vent pipe, or at a parapet wall where the coating has pulled away from the flashing.
- Granules in the gutter or downspout. If your flat roof has a mineral-surfaced coating, the granules are the UV-protective layer. Once they wash off, the underlying material degrades fast under LA sun.
- Visible cracks or blistering in the coating. Heat expansion and contraction causes the coating to crack, especially on roofs that get full afternoon sun in places like Woodland Hills, Canoga Park, or Northridge. Small cracks let water in; blisters mean moisture is already trapped underneath.
- Standing water still pooled 48 hours after rain. Low spots on a flat roof hold water. Quikrete Roof Coat is designed to handle some ponding, but persistent puddles slowly break down the coating and eventually find a seam.
- You feel soft spots when walking the roof. That means the substrate below the coating is saturated. By the time you feel it, the sheathing or decking underneath likely needs replacement, not just a recoat.
Replacement Cost & What’s Included
For Los Angeles homes, Quikrete roof coating and sealing work breaks down like this:
Small crack and seam repair: $470 to $825. Includes cleaning the area, applying Quikrete Roof Sealant or patching compound, and a written one-year labor warranty on the repair.
Partial recoat (up to 400 sq ft): $825 to $2,125. Includes pressure washing, spot priming, and applying one or two coats of Quikrete Roof Coat, depending on the existing surface condition.
Full flat roof recoat (up to 1,500 sq ft): $4,130 to $8,260. Two full coats, seam reinforcement, flashing detail work around penetrations.
Roof replacement including Quikrete materials: $9,440 to $23,600. This depends heavily on whether the decking must be replaced, the roof’s slope, and access difficulty. A 900-square-foot Valley ranch house roof with good access will land on the lower end. A steep-roof craftsman in Echo Park or Silver Lake with limited access lands on the upper end.
Every quote from Penhallow Remodeling includes the part cost and the labor cost as separate line items. You see exactly what Quikrete material costs and exactly what we charge to put it on. The number we give you in writing is the number you pay. We don’t send change orders once the roof is opened.
DIY or Call Us?
Here’s the honest split. If you see a hairline crack in the coating near a roof edge and you can reach it safely, a homeowner can apply Quikrete Roof Sealant to that crack as a temporary measure. What you should not do is get on a ladder and try a full recoat yourself. Los Angeles flat roofs are often 15 to 25 feet up, with parapet walls and soft spots that give without warning. Falls from roof height are the most common serious injury on residential job sites, and a roofer’s crew has the harnesses, the training, and the insurance to handle that risk.
The other reason to call us: matching the coating chemistry. If your existing roof was sealed with a solvent-based product and you apply an incompatible coating, you’ll be back on that roof in six months scraping your work off. We confirm compatibility before any material goes on. Call (936) 259-2607 for a free roof inspection and a written quote, including the exact Quikrete product we’ll use and what it costs.
FAQs
A properly applied two-coat Quikrete Roof Coat system lasts 5 to 7 years in Los Angeles before it needs recoat, though roofs with heavy full-sun exposure in places like Granada Hills or Sylmar may show wear closer to the 4-year mark. The critical factor is coating thickness at application and whether the underlying surface was properly cleaned and primed.
If your roof is past year 6 and the gutters are collecting granules, call (936) 259-2607 for an inspection and an honest read on whether you need a recoat now or can wait another season.
Most Quikrete-coated flat roofs can be repaired with spot patching and sealant if the damage is localized and the decking underneath is still sound. If water has already saturated the decking or the coating is peeling across more than 30 percent of the roof’s surface, replacement is the only fix that will hold.

A crack and seam repair typically takes 2 to 4 hours on-site. A full recoat on a 1,000-square-foot flat roof usually takes one to two days, depending on weather and how much prep the surface needs. Full roof replacement runs three to five working days.
