Unilock Roofing: The Los Angeles Owner’s Guide
If you’re searching for Unilock roofing parts in Los Angeles, you’re likely dealing with a specific failure: a cracked cap, a lifted edge unit, or a failed underlayment seam under your roof deck pavers. We stock Unilock-compatible roofing components and install them throughout Los Angeles, with most residential repairs running $590 to $2,360 including labor and materials. You’ll usually know something’s wrong when you spot water staining on a ceiling below a roof terrace, or when a paver shifts underfoot after rain. Here’s what to know before you call.
Key Takeaways:
- Most Unilock roofing failures in Los Angeles involve the pedestal system or edge restraint, not the paver itself.
- Installed repair pricing runs $590 to $2,360 depending on access, linear footage, and whether the pedestals need replacement.
- We’re an independent service provider. We’re not affiliated with Unilock, but we work with their roofing components every week.
- Isaac Pruett, owner of Mason Remodeling Co Los Angeles, has worked residential and light commercial projects across Los Angeles County for nearly two decades.
Which Unilock Models This Applies To
Unilock’s roofing line differs from their ground-level pavers in one critical way: the units are designed to sit on adjustable pedestals, not on a sand bed. That means the compatibility question isn’t just about paver dimensions. It’s about pedestal height range, paver thickness, and edge restraint profile. If you’re holding a cracked paver and hoping to swap it, we need to know whether it’s a 2-3/8″ thick roof paver or a thinner architectural unit, because the pedestal tabs are sized to the paver thickness. Mixing a ground paver into a roof system is a common DIY mistake, and it fails within a season because it isn’t rated for the uplift and drainage patterns of an elevated deck.
On the OEM-versus-aftermarket question: we generally recommend OEM Unilock components for the pavers themselves and quality aftermarket options for pedestals, shims, and edge restraints from manufacturers like Bison or Hanover. The aftermarket pedestals often offer finer height adjustment than older OEM pedestals, which matters on Los Angeles roof decks where drainage slope is already set and you’re matching existing elevations. We stock common 2-3/8″ roof pavers, pedestal ranges from 1/8″ to 18″, and edge restraint clips on our trucks for same-trip repairs.

Signs Your Unilock Roofing Is Failing
- Water stains on the ceiling below the deck. This almost always means a seam in the waterproofing membrane has failed, or a pedestal has punctured it. The paver above may look completely fine, which is why roof deck leaks confuse so many Los Angeles homeowners. The problem is under the pavers, not on top of them.
- A paver rocks when you step on it. In Los Angeles, thermal cycling plus occasional heavy rain compacts the pedestal shims over time. A rocking paver means the shim stack has compressed or the pedestal head has cracked, not that the paver itself failed. Ignoring it leads to edge chipping and eventually a broken corner.
- Cracked or spalled paver surface. Unilock roof pavers are dense, but they’re not immune to point loads. A dropped patio table, a heavy planter set down hard, or a pressure washer held too close can spall the surface. A cracked roof paver is a safety issue because it can break further under foot traffic.
- Gaps opening at the paver joints. Roof pavers are installed with small, consistent gaps for drainage and thermal movement. When gaps start widening unevenly, the edge restraint has loosened or a pedestal has settled. Left alone, pavers drift, and the whole field can shift toward the drain.
- Standing water that doesn’t drain after rain. Your Los Angeles roof deck should drain within an hour after rain stops. Puddles that linger mean the pedestal heights were set wrong from the start, or the membrane has developed a low spot. Standing water is the number one accelerated killer of roof membrane systems.

If we discover membrane damage while the pavers are up, we stop and show you before any additional work proceeds. Our written price covers parts and labor. No change orders without your sign-off. Work is covered by our written guarantee for 365 days from completion, and if a repair fails in that window, we return at no charge. That’s the deal, stated plainly.
DIY or Call Us?
What you can safely do yourself: pull up a loose paver and photograph the pedestal underneath, check for standing water after rain, and note where the deck drains. Those three observations save us time on the first visit. What you shouldn’t do yourself: disconnect or adjust pedestals without knowing the paver weights involved. A 2-3/8″ Unilock roof paver can weigh 50+ pounds, and when they’re wet they’re heavier. If one slips out of your hands over a membrane, you’re dealing with a puncture repair that costs far more than the pedestal you were trying to fix. Roofing systems are not ground-level paver patios. The membrane is a waterproofing layer protecting the living space below, not a sand bed that forgives mistakes. If you’re uncomfortable lifting pavers or the area is near a roof edge, call us at (213) 632-5711 and we’ll take it from there.
FAQs
The pavers themselves can last 25 to 50 years in Los Angeles because they’re dense concrete units, but the pedestals and edge restraints typically need replacement every 12 to 20 years depending on sun exposure and drainage. The membrane below is usually the first thing to fail, not the Unilock paver on top. Call (213) 632-5711 and we’ll assess what’s actually failing before recommending any replacement.
No. Concrete roof pavers can’t be patched in a way that restores structural integrity. The repair always looks worse than the replacement. Replacing a single paver is usually the least expensive part of a roof deck repair, often $118 to $354 installed. Call (213) 632-5711 for an exact price on your specific paver size and color.
Single paver or pedestal replacements are typically done in one visit, usually 2 to 4 hours on site. A full roof deck re-set takes 1 to 2 days. We’ll give you the timeline in writing with your quote.
We stock common Unilock roof pavers in Los Angeles in standard colors and sizes, plus pedestal components and edge restraints from Bison and Hanover.
