Unilock Roofing: The Huntington Beach Owner’s Guide
We stock and install Unilock-compatible roofing components in Huntington Beach, with most replacement parts running $400-$1,800 installed depending on scope. Many Unilock roofing failures show up first as lifted coping stones or separations at the parapet wall, especially after the Santa Ana wind seasons we get here. If you’re seeing gaps or water staining on an interior ceiling below a Unilock roof area, the coping, membrane flashing, or drainage assembly is likely the culprit.
Homeowners usually catch this during our dry, windy springs, when displaced stones or visible membrane edges become obvious from the ground. In Huntington Beach, the salt air and thermal cycling between marine layer mornings and 85-degree afternoons accelerate the adhesive and sealant fatigue that Unilock systems rely on at their joints.
Which Unilock Models This Applies To
Unilock’s roofing line centers on pedestal-set paver systems and integrated coping assemblies, not traditional shingle or tile roofs. The specific parts we replace most often are the adjustable pedestal heads (Series PH-1 through PH-4, identifiable by the gray polymer body and stainless-steel threaded stem), rubberized paver spacers, aluminum perimeter edging with integrated drip flashings, and the EPDM or TPO membrane strips that seal parapet-to-coping transitions.
To identify your exact part, look for the stamped code on the pedestal base, usually visible if you lift one corner of an adjacent paver. The PH-2 and PH-3 heads are not interchangeable, the PH-2 uses a broader circular flange that won’t seat properly in a PH-3 base. For membrane work, Unilock specifies either 60-mil EPDM or 45-mil TPO depending on the original install year, pre-2016 systems are almost always EPDM.
We source OEM Unilock pedestals and coping profiles through their regional distributor in Anaheim, but for membrane and fastener hardware we often specify Carlisle or Firestone equivalents that meet the same ASTM specs at lower cost. The Haven Standard requires us to document the substitution in writing before installation, so you know exactly what you’re getting.
Signs Your Unilock Roofing Is Failing

- Loose or rocking pavers underfoot. The adjustable pedestal head has stripped its threads or the self-leveling gasket has compressed past recovery. In Huntington Beach, UV exposure degrades the polymer faster than inland climates, we typically see this at 8-12 years instead of the 15-year design spec.
- Water staining on interior ceilings near exterior walls. The coping-to-wall seal has failed, usually at the membrane termination bar or where the EPDM meets the stucco weep screed. Salt accumulation at the parapet accelerates the adhesive breakdown.
- Visible gaps between coping stones. The thermal expansion joints have lost their backer rod and sealant, allowing wind-driven rain to penetrate. Santa Ana events in Huntington Beach will push water through gaps as small as 1/8 inch.
- Pedestal bases sitting in standing water after rain. The drainage mat or weep holes in the perimeter edging are clogged with debris or corroded shut. This is more common on roofs near Pacific Coast Highway where airborne particulate is heavier.
- Aluminum edging pulling away from the wall. The expansion anchors have backed out of the substrate, often because the original installer missed the structural deck and fastened only into the fascia board. We check this with a sounding hammer on every inspection.

Most Unilock roofing repairs in Huntington Beach fall between $400 and $1,800, with the upper end covering multi-section membrane work or pedestal replacement across a larger terrace area. The range moves with access difficulty, roof height, and whether we need to match discontinued paver colors. Under Clause 1 of the Haven Standard, you get a written line-item quote before we start, no exceptions. The 365-Day Done Right Promise covers both parts and workmanship.
DIY or Call Us?

There’s a clear line here. A homeowner can safely lift a paver to check the pedestal code, clear debris from drainage channels with a shop vac, or photograph damage for our review. What you should not attempt is membrane welding, pedestal adjustment under load, or coping removal on a parapet wall. The fall hazard is obvious, but less obvious is that improper membrane sealing traps moisture in the wall cavity, we see $8,000-$20,000 in rot remediation behind botched DIY roof repairs annually in Orange County.
We carry PH-series pedestals, compatible membrane rolls, and sealants on our Huntington Beach service trucks, so most Unilock roofing repairs complete in one visit. Call (657) 288-3368 and we’ll schedule a free inspection with a written price before any work starts. Measure twice, price once, and put it in writing.
FAQs
In Huntington Beach’s coastal climate, expect 12-18 years on pedestals and coping assemblies, 15-25 years on membrane if properly maintained. Salt air and thermal cycling shave roughly 20% off inland lifespan projections. Call (657) 288-3368 for an exact condition assessment, estimates are free.
Membrane patches and pedestal re-leveling work in some cases, but we won’t patch a pedestal head with stripped threads or a coping seal that’s failed across multiple joints, the repair costs more than replacement within two years. We document what’s repairable and what isn’t in your written quote. Call (657) 288-3368 for a line-item breakdown, estimates are free.
Most pedestal or membrane repairs complete in 2-4 hours. Full coping re-bed on a typical Huntington Beach residential terrace runs one day. We bring the parts on the first visit, so there’s no return trip delay. Call (657) 288-3368 to schedule, estimates are free.
We stock PH-series pedestals, compatible membrane, sealants, and perimeter edging on our Huntington Beach trucks.
